    It is generally accepted that macOS is immune to viruses and malware. In general, this is true, because, for the entire history of the operating system, viruses written for it can be counted on the fingers.

     

    I want to understand why this is happening and what to do in order not to get infected with those rare instances of malware.

     

     Among my acquaintances who use Mac device, there is no a single person who has an antivirus or someone who would say that he got a malicious code or any virus. There are several reasons for this. Of course, one can argue that macOS X is a Unix-like operating system and, therefore, it is invulnerable. We reject this primitive thought since there are some viruses for macOS, which means that the system, like any other, is vulnerable.

     

    The main reason why there are so few viruses written for Mac is that there are very few Mac devices themselves. If we compare the number of Windows personal computers and Macs that exist today in the world, it turns out that the Mac devices make only 7%. Attackers who want to steal credit card numbers are more likely to be interested in the audience of Windows PC users because of their large number.

     

    Some say that to protect your Mac from the hypothetical possibility of installing malicious software, you need to install an antivirus. This is the most logical solution, according to most users.

     

    Here is the list of viruses that I found information about:

     

    1982: Elk Cloner

    1987: nVIR

    1990: MDEF

    1995-1996: Concept / Laroux

    1998: SevenDust 666 / AutoStart 9805

    2004 and 2006: Renepo / Leap-A

    2007: RSPlug-A

    2009: iWorkS-A Trojan

    2011: MacDefender

    2012: Flashback / SabPub

     

    What we have here: only 10 malicious programs. In my opinion, only MacDefender represented a real threat to users of macOS - stealing credit card numbers. As you understand, security updates have already come out for these viruses, and they do not represent threats.

    Let's return to antiviruses. What do you think, given the information written above, how often do you need to update the antivirus database for Mac? The answer is once a year or less.

     

    Antivirus software for macOS is more harmful than useful. There is convincing evidence that Kaspersky AntiVirus very actively collects information about the user and sends it to its servers. There is information that computers with Kaspersky AntiVirus can participate in DDoS-attacks at the discretion of the developer of this antivirus. It's worth thinking about whether you need a Trojan program and also pay for it.

     

    You still have to be careful not to get malware on your Mac device. Some malicious software tools like Safe Finder may also collect your data or show unwanted ads.

  3. I recently purchased an R9 Fury X off of eBay for a couple reasons, the first being for the giant performance increase from my 380X, and the second being that I can mine with my 380X.

    And if any of you are interested on how the new card performs, I made a video on the topic:

    Answer: no 

    reasoning: the App Store has about 6 or 8 split window browsing apps. One of the most popular is Split by Savy soda. The issue is that you have to go back and forth typing new searches. Ideally the app would mirror the first search to get both windows to the first google page, then un-mirror allowing the user to tap through multiple links without pressing the back button which wastes loading time. Then re-mirror and un-mirror. Maybe with some ai or something. A solution to the "back load time" is another app which promises zero latency back presses. That app is called "fastback." But there is no practical purpose for split windows. Searching time actually goes down going back and forth. For background music there are other apps that play in the background. You do not need to sacrifice half your screen to play music.

  5. The other day I found a Gamer's Nexus video in my subscription feed. It was Steve Burke criticizing a magazine's article on how PC building is "hard" and to prove it wasn't, would do a speed build.

     

    Admittedly I didn't watch the whole video, nor did I read the article in question. But my overall takeaway is this: to all you people who build or built their machines, stop saying it's easy as if building a PC is like operating an elevator or using a phone.

     

    Now ignoring the other aspects of building a PC that conveniently get ignored, like identifying your needs, planning your budget, researching parts, testing, and if needed, troubleshooting, of course it's easy to build a PC if you've done it before. But to a fresh newbie, it still may be a nervous experience that really isn't all that easy for them.

     

    To put in another way, I think about the time I was leaning how to ride a motorcycle vs when I ride now. I was nervous about shifting gears around except up when accelerating and down when coming to a stop, I had trouble with the clutch, hills were a problem, going down even past 45 MPH scared me, lane splitting was something I dared not to do with moving traffic.

     

    Now, all of that no longer matters. I can shift just by my gut feeling. I have competent control of the clutch. I can manage most hills (though I'm sure San Francisco will humble me in a second). Highway speeds feel normal. I even lane split in moving traffic (and I survived LA).

     

    These are all more or less "natural" to me. I don't have to think about how to do the action, but merely when to do it. So riding a motorcycle is easy to me. I think it's easy. But it's not.

     

    Granted building a PC isn't this complex, risky, or what have you, but I wanted to illustrate a point. I'm sure most of you who built their own PC consulted the internet a few dozen times throughout each step of the process. I'm sure you spent a lot of time mulling over what's good for you or what's not. Or maybe you didn't and just copied someone else's build (though I'd argue you're sort of cheating). I'm sure when something went wrong, you nearly needed a change of underwear or blew a few blood vessels.

     

    If PC building were really easy for anyone, nobody would need to do or worry about any of this.

  6. This is a perhaps a more eloquent and elaborated presentation of what I was wanting to speak in the thread 7-times Microsoft MVP finds Windows 10 Enterprise collects too much data at minimum, calls for legal action.

     

    The relevant links from that thread are these:

     

    Windows, Spying, and a Twitter Rant

    Screenshots showing high levels of contact with Microsoft servers after employing all efforts to stop data-transmission

    Additional screenshots of further Microsoft server activity, discovered later

     

     

    I would like to give some personal commentary to the subject that those links are about.

     


    If a politician steals millions of taxpayer dollars, which is only a few cents from each person, they go to jail. So what about when Microsoft is continuously piggy-backing on everybody's PC systems to enrich themselves? Microsoft is using people's own hardware, software licenses, electricity, computing power, data, time, and private activity for non-sanctioned business use, and the profit of Microsoft's executives.

     

    Microsoft's data-mining is no different than a virus that is distributed to people's PCs to min mines digital coins using their CPU and CPU power, with the earnings being deposited in the e-wallet of the virus' creator. You could also look at it like someone setting up a mining farm, but connecting all their systems to their neighbour's electricity supply - except that in the case of Microsoft's data-mining, they are not using their own hardware, software licenses, and everything else, but those of the people whose systems are sending data to Microsoft... and so the coin-mining virus is a more suitable analogy.

     


    Every aspect of Microsoft collecting data from people's PC systems and personally-owned Windows licenses is already established in law as being illegal. But some people are taking a bit of time to work through the understanding that leads to that recognition, because software-license owners are traditionally just not on the lookout for stuff like this and usually just focus on using their software, and not technical legal aspects or ethical implications behind its operation. Also, Microsoft being a well-known company whose products people have used for years throws a lot of people for a loop, I think, because they are used to just assuming that whatever they're doing must check out, somehow. Well, this doesn't. It's illegal from head to toe.

     

    It's theft, but it's also Unjust Enrichment - which is the situation where one party is making profit for itself at the unjust expense of others. A current UE case involves ZeniMax targeting Samsung for Unjust Enrichment over VR technology that ZeniMax claims belongs to them but is profiting Samsung.

     

    If you unilaterally utilize somebody property, or copyrights to make yourself money, who is legally entitled to the proceeds? Legal entitlement goes to whom the required property and rights that the profit is dependent upon belong to. 

     


    A person who argues that by using Windows 10 a person agrees to send Microsoft their data would be wrong, because sending Microsoft data is not essential to making use of the software functionality that was paid for when buying a Windows license, and so conditioning usage of the paid-for functionality on unrelated and Microsoft-profiting access to personal and private data would not pass the Reasonable Person test.

     

    Also, such an argument would be in ignorance that the data sent to Microsoft doesn't come from only the owned software license, but also a person's personally-owned  hardware, electricity, computational time, uniquely-generated data, and personal / private activity - things for which there can be no entitlement for Microsoft to use any more than a car salesperson can claim that if you buy a vehicle from them, then they have access to use your garage and everything in it, including the power source hooked up to it.


    Additionally, the idea that Microsoft could exert any authority over an instance of the Windows OS after they've sold the license that represents the OS instance to somebody is a violation of the first-sale doctrine, which makes clear that such authorities and privileges pass to the owner of the property, in this case, the owner of the software license and the instance of the OS it represents, once it is sold. And the SCOTUS has just made a unanimous, 8 - 0 in favour, re-affirmation that decision-making rights leave from the seller to the buyer at the first-sale of an item.

     


    I fully believe that seven-times Microsoft Most Valuable Professional award recipient Mark Burnett is right when he says "What we need to do is fix this, even if that means getting lawmakers involved. It can only get worse from here". Though, I believe it is important for big reasons beyond simple control and security of the OS.

     

    Microsoft is stealing digital property, computational power, and electrical resources from everybody, and is making non-licensed usage of people's hardware property, the housing of that hardware, and are exploiting people's personal behaviours while those people are staying within their personal and private spaces (non-online activities). And in the process of violating Windows license-owners' rights over their property, resources, time, and behaviour, Microsoft is unjustly enriching its company and executives.

     

    If action is not taken against those who commit these violations, then all established societal and legal notions of what property is, who possesses decision-making rights over it, how much a person can use their position to unfairly exploit others against their natural desire... then all existing understanding of those things becomes argued against, and a precedent is established where a person's property is anyone's to use by unilateral decision, and a seller of goods can enslave and overrule aspects of people's own private lives and property as part of their conditions for their sale. Effectively, a sale becomes not a transaction of goods for money, but a mechanism for enslavement and subjugation, with the seller acting as if they held a commercial license over a plethora of the buyer's possessions and entitlements.
     
    A person whose personal and private PC system environment (non-online spaces) is sending data to Microsoft through telemetry, data-collection, and analytics of their behaviour is an employee of Microsoft who does not get paid, or receive any company benefits.

  7. Hello,

     

    So the other day, I was bored and thought, "You know what, I want to learn how to design a working instruction set," and thus I have been working out the details for a simulated processor using my own custom instruction set rather than getting some homework done that I really should be doing.

     

    Here is what I currently have worked out:

    Welcome to the first edition of my Lyft blog series. In this series I will tell you some interesting stories from my Lyft rides. Some of these are personal stories customers tell me while I drive, others are events that occurred in the car itself while I was driving. This volume represents the most interesting stories from my first 100 rides (excluding two special ones I'm saving for a top 10 list later this year).

     

    Before we get started, I'd like to offer a disclaimerAll guest's names will be changed, as well as any other personal details such as location, age, etc. This little blog series is intended to entertain you, not to embarrass the customers. Additionally, I do not know these people beyond my meeting them during their ride, so I can not confirm all personal stories are accurate; all back seat stories are accurate as they occurred in my car during the ride itself.

     

    I don't know yet how many of these entries I'll make or how popular they may or may not become, but to maintain a clean appearance each story will be enclosed within a spoiler tab. Some stories are longer than others, so this should help keep things looking clean and organized. 

     

    Enjoy!

     

    Ride #3, a warm up for what's to come...

    Spoiler

    This is my third ride, ever. My first two went pretty well, I was able to drive them to their destination without killing anyone, my customers in both rides were happy with my 'fancy' phone charger setup and my WiFi, and the app navigated me without any major issues. I ignorantly believed all my rides would be fast, easy, and mildly entertaining. Then I got my third ride, and reality came crashing down on my hopes and dreams... ok, it wasn't that bad, but this is when I realized my rides were not all going to be calm and peachy.  

     

    I picked up a young woman (18) and a young man (similar age) at a house in the suburbs of Sunnyslope, WA. When I arrived I saw several bags and luggage items in the front yard, so my first guess was "Oh, I must be taking this young couple to the airport." No, not at all. When the couple came out of the house I got out of the car and helped them load their items in the trunk. I could immediately see the young lady was upset, but the male, presumed boyfriend, was not. I wasn't sure what to make of that, but I didn't say anything.

     

    The ride was very quiet at first, I welcomed them to my car and answered the lady's question about which charger worked with her phone, but otherwise no conversation. This silence only lasted about 5 minutes though, as shortly after leaving the neighborhood the female passenger began crying. I offered her some tissues, and she opened up about her whole situation to me. Apparently her step father doesn't approve of her decision to become a professional cartoonist, so he beats her. Today he was drunk, got into some sort of fight with her, and kicked her out of the house. She feels powerless because she doesn't have enough money to move out but she's 18 now so she can't report child abuse. Of course I listened to her and let her vent, but I kept my opinions to myself. 

     

    She got really emotional. The man didn't do much, but eventually offered her a "Blueberry & Chocolate Cheesecake W/ Truffle Oil" vape. I don't allow smoking or vaping in my car but she was so upset, I didn't say anything. The vape didn't calm her down though; she kept going on and on about how this step father was ruining her life and how she wanted to be left alone but she couldn't afford to move out, etc. I keep a few tiny teddy bears in the front of my car for children, so I gave one of them to her and she appreciated it. Now, her story changed to how much she missed her biological father, and how he would give her teddy bears all the time, and how she lost him too early, and I could see there was no way to make this girl happy!

     

    When we finally got to her destination (which turned out to be the man's home) the couple thanked me for listening to the story, and for giving her the bear and the tissues. I helped them move their luggage, the woman realized she had dropped her vape oil somewhere, searched my car for a few minutes, then gave up and told me she would give me a "huge tip" and asked that I call her if I found the oil.

     

    The next week I got my paycheck, and saw that there was no tip on her fare. Nice!

     

    The Worst Kind of Revenge

    Spoiler

    This story takes place on a cold, rainy Friday evening. I picked a man in his late 30's and a child, an eight year old girl. The girl was too short for my seat belts in the back seat, but dad had a small folding contraption with him that lowered the seat belt height. (I usually turn away parties with small children if they don't have a child seat, I don't need a ticket or worse, and Lyft's policy is clear: it's the parent's responsibility to provide a child/booster seat, not the driver).

     

    The journey was about 2 hours. The girl kept to herself, playing with some sort of foam tablet (maybe a kid's fire tablet or something) and dad was talking with me about simple stuff, like traffic, cars, life in WA, nothing to heavy or serious.

     

    Then about an hour in, the girl had fallen asleep and dad changed the subject to his personal life. He told me about her mother, and why mom wasn't in their life. I'll spare you the details, most of it was the typical stuff that drives couples apart, but there was one part that stuck out: she was pregnant with their second child and tried to use that child as leverage for a marriage. Dad wasn't ready for that yet, and when she saw that he was not going to 'pop the question' she broke up with him, left the then 3 year old child with him, and aborted the second child just shy of the end of the 1st trimester. 

     

    Now, I have my personal feelings about abortion, but I think most sane people, pro choice included, would agree that aborting a child as an emotional attack on the father is not acceptable. From what he explained their relationship was great at first, but it was on again off again for a while, then they had the first girl, stayed together for a year, then he raised her alone for a while, then mom came back, got pregnant, and demanded they be married or she would abort the child. He thought that was a bad idea, because they had "serious shit" to work out, and he didn't think marriage would be appropriate. 

     

    This was all five years ago, and today dad says his daughter has no meaningful relationship with mom. She knows who her mom is, and has seen her a few times but dad tried to keep them apart. Dad justifies that mom had her own husband and children now, her own life, and it's better to avoid breaking his daughter's heart then allow them to regroup just for mom to leave her like she did him. I understand that logic, but without knowing more details I can't say if that's right or not. 

     

    Dad showed me some photos at different red lights, and along with how he speaks about his daughter I believe that she is incredibly important to him. He has fears that mom will try to regain custody in the future since mom and dad never took legal action to secure custody, but I told him that's not too likely when he can show a court evidence that he's been a major part of his daughter's life and that mom has had little interest in reconnecting up to this point. 

     

    It was an interesting ride. I gave his daughter a teddy bear and he tipped me $10 cash. I hope he can find a new mother for that girl! I can't imagine being a single parent is easy... and that mother aborting the child under those circumstances, if they are just as he said, is absolutely horrible. 

     

    Attempted Exhibitionism in the Back Seat

    Spoiler

    Ah, Saturday night. 1 AM. Drunk people in almost every ride. My kind of night! Drunks can be really entertaining, and this is just one example. 

     

    I pick up two young woman and an older man (I'd say the woman were in their 20's and the man was probably 50 something). They were all drunk, and babbling about their plans for later that night. Talking about what kind of cocktails and mixes they could make, who would be there, etc. Typical drunk ride. But then, one of the ladies tries to pull down the man's pants. She wasn't doing too well, so he helped her, but driving all I knew at that moment was there was a lot of bumping and shifting around going on in the back seat. He was in the middle seat, but the road was too curvy for me to take my eyes off the road. 

     

    When I did get a chance to look back I saw the man in his shirt and underwear with one of the girls rubbing his, bulge, and the other filming vertical video. I didn't say anything. I just looked at them and they stopped. He put his pants back on and they remained silent for remainder of the short trip. The girls were embarrassed but the man didn't seem to be.

     

    I dropped them off at their destination and they said nothing, not even goodbye. I received no tip. But the story doesn't end there. The next day I was woken up by my cell phone ringing. When I answered it was one of the girls saying she left her portable battery pack in my car last night. I asked her who she was, since I had many rides that night, and she responded with her name, then clarified "I was in the group that pleasured the man in your back seat." That was hilarious.

     

    P.S: I was not able to locate her battery.

     

    The Magic Drill (My favorite on this list)

    Spoiler

    It's Wednesday afternoon. I receive a request to pick someone up at an extended stay hotel. When I get there a man in his 40's gets in the car, with a drill. He asks for a bottle of water and I give him one. As I drive him to his stop he explains to me that he works as a private detective, and often works with the Seattle PD. He told me he didn't have much time because he's on his lunch break right now (from the hotel? As a PI? Ok...) but that he needs to see his friend. All this time he's cleaning this drill he brought with him. It wasn't new, it has scuff marks and sharpie on it, but he sure seemed proud of it. 

     

    I get to his stop and a woman gets in the back. She honestly looked like Wendy from Breaking Bad. Seriously. Basically, this is his friend:

    Image result for wendy breaking bad

     

    He now wanted me to take him to a second stop, then a third. He only requested me for one stop though, so I asked him to re-request me after I ended the ride. He did, and as I waited for him to re-request his friend started talking to him about the drill. She thought it looked "good", and that it was "pretty cool". She even wondered how he got "such a nice drill". For his second stop I took him to a 2nd friend's house. The first friend, Wendy's doppelganger, stayed in the car and played with my phone chargers while the man ran up to this 2nd friend's door. He spent a whole 12 minutes talking to this friend, presumably about his drill. He showed it off and was holding it as they talked. About 6 minutes in Wendy started eating my strawberry suckers. (I have some candy in the back seat for my guests) It sounded like some wild animal... loud and unorganized slurping and crunching sounds. And as the time elapsed she ate them faster and faster. 

     

    Finally the man got back in my car and I took him and his 1st friend, back to the first friend's house... Why did this woman get in my car to begin with? What is the logic in this ride? How long is his lunch break? WHAT IS SO SPECIAL ABOUT THE DRILL? This guy defies all logic! Who is the lady to him, beyond being a friend? Why does she gobble up candy like those kids in Invader Zim?

    Living In A Box

    Spoiler

    A short and sad story. I picked up a man at a house and took him home. The ride itself was not very interesting, but the destination was. His 'home' consisted of a wooden box, roughly 4' x 10' x 6' kept under the gap in some stairs at an abandoned hotel. I'm serious, he built himself a little shack just big enough to lie down in and sleep, with no windows and a heavy duty lock on the outside. I hope he can get a better home! I wish I could help but I don't have that kind of money. He seemed fairly healthy, in the mind I mean, not like some homeless individuals. But clearly he has enough money to afford a smartphone with service and a Lyft ride. I don't know, maybe it's just an act to get money out of sympathetic Lyft drivers.

     

    The Trekkie

    Spoiler

    This one is pretty fun. Not a drunk or a sad story, just an interesting one. I picked up a man at the mall and took him to the hospital. He was buying some gifts for a loved one recovering from a car accident. He was very nice and talkative, and he told me about all the Star Trek actors he's met. I went back to my dash cam footage from that day to get this list for you, he claims to have seen: Peter Weller, Jeri Ryan, Kate Mulgrew, Carolyn McCormick, Wil Wheaton, Jennifer Lien, Eric Menyuk, and Marc Alaimo. There were a few more I couldn't make out well enough. 

     

    He talked about how he met these actors at various events, and some he followed to non star trek shows or conventions. The man told me about some of his trips, like his one to Las Vegas. He and his family went to Las Vegas for a convention and on the strip. There were woman dressed in BDSM outfits whipping men's rears as they passed on the sidewalk, and one of them hit his daughter in the back of the head. After dealing with that, he and his daughter went to the convention where they got pictures with a few different actors. He says his "Jr. Trekkie" felt meeting her favorite character made the night worth it. A nerd's dream I suppose!

     

    I like star trek myself, but I think this guy was one of the biggest fans in the community. I think I would skip the show if someone assaulted my daughter...

     

    That's it for now! Some of these are more interesting than others, but like I stated above I'm keeping my 2 best stories for a top 10 list... hope you found at least one of these stories interesting!

  9. I know it's been ages since I did a blog about SpecsBoss and so I decided to tease what's gonna arrive in SpecsBoss 1.0 .

     

    So, in no particular order are a bunch of changes coming soon....

    • I've updated the specs detection library, AluminiumCore Library,
    • I've added GPU Codename support for select GPUs (Mostly GPUs from GTX 600 series or Radeon HD 5000 series or newer)
    • The SpecsBoss application has been modularized SpecsBoss so that it can support more languages in the future
    • Changed to a new offline installer to allow an easier installation process
    • Added a custom and up to date build of AutoUpdaterDotnet library to SpecsBoss to allow for easier checking for updates. AutoUpdaterDotNet has not recently been updated or maintained by the original author and thus I thought it'd be a good idea if we improve upon it to ensure it provides a good updating mechanism for SpecsBoss
    • Added CefSharp.WinForms dependencies so that we can hopefully provide a more seamless experience if the user needs to see a webpage such as the SpecsBoss Wiki.
    • Translating SpecsBoss into Korean
    • Separated themes so that there is a fully implemented Light and Dark Theme as well as a theme customization tool.
    • Added Advanced OS Detection
    • Added BIOS Detection
    • Added ability to install CSMark alongside SpecsBoss and able to be run it from within SpecsBoss.

     

    And that's it for now. I don't know when this'll come out cos I'm bust. A lot of what's on the list of to do has been done but there's still some work to do. I can't promise that there'll be frequent updates initially but hopefully when I'm less busy, iId like to push out updates.

     

    If you'd like to see builds before the 1.0 release then do check out the GitHub SpecsBoss page -> https://github.com/AluminiumTech/SpecsBoss/ and if you'd like to check out the releases then go here -> https://github.com/AluminiumTech/SpecsBoss/releases  . I'll probably push out a few more builds before release 1.0 ,

     

    That's it for now :).

  10. Where do I begin..

     

    Having been a member here for over four years and a forum user for many more, I might know how the communities work. Smaller ones are tight-knit, larger ones are one big family with the groups the like to talk together. It's simply how our big, digital families work. But we're still family even with our differences, right? Not all of us get along 100%, some of us disagree almost absolutely with others, I know I'm one of them but we all have our opinions and reasons (or beliefs) for them. Yet very rarely, even here, does it get out of hand to the point there needs to be a talk.

     

    So what is the point of this blog entry you might be asking? Well, some of you guys are a real riot. The more veteran members know what I've written above. Newer ones however, it's not always the case.

     

    Aphexxis, Aphexxis, Aphexxis..

     

    You lovable ball of.. well.. something. I'm not sure what to classify you as yet, it'll come in due time though I'm sure.

     

    Today you posted an interesting thread, it's still up so hell, I'm posting about it here because I can, otherwise mods would have removed it completely and then I can't "officially" talk about it. But I will, so here we go.

    As this thread as been so gloriously nuked while I was typing up my reply (shown below, if I remember), there's something all new forum members should know when they sign up to any forum. Read the forum. Get a feel for it. Know the community. It's a good practice! There's many popular forums out there, but we're not all the same. Some are nicer, others totalitarian, but all one big family in their own way. The first forum I joined was not as large as this community, but still had a very healthy amount of members when I joined. But the thing you always have to know is: am I among like minded individuals? Not in the sense that we all agree Corsair power supplies are based-firestarters, but that you can have discussions in the same flow of thought you would want to have. "Can I interact with them? Are they too edgy? Too soft and unwilling to have a hard discussion with disagreements?" Etc.

     

    So what do you do? Read the forum.

     

    Go through the Tech News section, see what people talk about, how they interact with each other. You're a stickler for builds? See the build sections and look at how our big happy family works. Because that's what we are, one big happy family*.

     

    *Terms and Conditions may sometimes apply just a little bit

     

    Maybe you'll go think "hey, I like these people, they're friendly enough and don't toss people immediately under the bus!" And you would be right, until you do something like you did.

     

    See, heated discussions happen. Ask the people that don't like me not because I will aggravate you the moment you show how easy it is, but because I will disagree with you with reasons and tell you why. They'll decide whether or not they think I'm right or wrong, and that's okay. That's not what me and others are always here for. Some people like me sit in the back until we feel like poking your brain in the way we see fit, it's fun. It gets discussion going. And maybe somebody might think a little bit more about what they believe. In a good way, thinking is always good.

     

    Our big, happy family does not agree on everything. In fact you might say it's split down the middle sometimes. AMD? Intel? Nvidia? Apple? Google? Microsoft? The list goes on, and it repeats many times, many weeks, all the time.

     

    Check our Tech News section, you'll see how we interact. When we agree, and when we don't.

     

    But you might see something peculiar about our interactions, there's not a lot of mud flinging without any basis. Opinions more than "I said so" exist and are spoken. Intelligent discussion happens and unintelligent discussion happens in tandem like the dance we always go through. And at the end of the day we can still end a thread peacefully without going down the OP's throat that the thread should have never existed.

     

    So, Aphexxis, why you, you might ask?

     

    Good question!

     

    You've made it too easy. I've managed to get you to lock your own thread quicker that most of the low post wonders that come through this side of the internet, and you succeeded spectacularly at doing what I wanted. I poked your brain, and you responded. Congratulations, you win a redeemable coupon for a digital cookie expired already.

     

    We've had plenty of threads about AMD and Intel, Ryzen and Bulldozer, Intel with their Core series. But few have been like yours. You don't even know what side you're on half of the time in your own original post and yet you want some sense of intelligent discussion? Here's a forum tip: you did it wrong.

     

    Threads about our opinions on things like Bulldozer have come up time and time again, and even though there are rules for not going "which is better, FX8 or an i7?!" not all of them get locked. Because not all of them are.. you guessed it.. asinine.

     

    What makes your thread asinine? Why do you think I believe you went about this the wrong way? Well it's simple, you were hostile from the very beginning. Is idiotic rhetoric a thing? Yes, most ideas are concepts are all true to an extent. What you did wrong is instantly assuming any amount of disdain or displeasure with a CPU is instantly "idiotic rhetoric." Oh and that goes back to you not even knowing what side you're on. You didn't have an opinion, just ramblings without basis. On one hand you have people blaming Intel for Bulldozer not meeting expectations and letting consumers down, and on the other hand you have people blaming AMD for Bulldozer not meeting expectations and letting consumers down.

     

    At least try to give an angle we can respond to, that's the least you can do. "Why do people think Bulldozer sucks? Go!"

     

    Then we could have had something. My morning could have been made better by the brain pickings of what people think, even though there's a general consensus on Bulldozer by 2017. *psst* It had problems.

     

    But, when you are told your thread does not make sense, you attacked other members. See, here we might disagree, but we don't do what you did. Veteran members are around for a reason, we've gone through these scuffles before without being banned. We might know there's a line not to cross, and so should you. If someone thinks your thread is pointless, tell them like the adult you say people like me should be. Why should I be held to a higher standard when I just sit back and watch you ramble and sling names? I'm just going to sit here and hand you a shovel to continue digging your own hole deeper. Give us reason your thread is not pointless to us. You might have a rocky start, many of us do, but give us substance. You did not. And you got everything back in full.

     

    My reply to you if the thread wasn't nuked by mods is below.

    Ahh let us see here..

     

    define asinine.PNG

     

    I think I'll go with "foolish" to describe the contents of your original post. So to start, you create a post on a forum that has very heated discussions about the performance of AMD products without any attempt to create positive, intelligent discussion. Where should I start?

     

    "Did in any of the FX 81xx FX 83xx life time get what the community rambled on about?"

     

    Low hanging fruit:

    ### Blog edit. The low hanging fruit section is not to demean you or insult you in any way. It's a little nudge of "Hey, maybe give this a shot and we'll respond better." ###

     

    Slightly higher hanging fruit:

     

    The FX8 series has been discussed heavily here on the LTT forum, its died down in the past two years or so but crops up every now and then but there has been a general consensus on the topic. It was a solid CPU with some major pitfalls in the architecture design. It was ahead of its time and poorly implemented, not to mention software was simply never made to make full use of the architecture.

     

    Two cores per module is great for when you want to run workloads in parallel but the general consumer doesn't use software that could benefit a lot from it. That's mostly in servers, completely different things for users. 

     

    Running software on it such as games only came in to problems with the architecture because of the two core per module design, sharing resources just creates delays because one thread might have to wait on another. Things of that nature. It can become a real headache in the performance department. General consensus? If you can get it cheap (2014 era, $200 and dropping) then it's okay for a light build, but it's worth getting something like an i7 if you need more processing power.

     

    "how Windows is unoptimized, not the CPU being designed how it is."

     

    The only people who thought the problem was Windows, same as this latest bout with Ryzen, are the ones who are die-hard fans of AMD and can't take "no" in a sense for an answer. The fundamental problem with Bulldozer was its architecture, not Windows. Windows ran perfectly fine with Bulldozer, it assigned work correctly and as efficiently as it can, the problem is you're trying to run heavily serialized code on something made for parallel work, it ain't gonna happen.

     

    "How intel is putting code in games to slow FX down.. yeah they went there."

     

    Same situation as above, and debunked all the same. Intel cannot change how x86 runs. The FX8 series is great for some things, but not most.

     

    "How everyone is transpiring against AMD and are now victims to intel owners."

     

    See above, this is just repeating the same thing in a different way, again.

     

    "How FX has 8 cores so it's bettererererer."

     

    In a roundabout way, the FX8 is better because of having more cores, the IPC was never near Intel with their Core series but if you could parallelize code it would run leagues better on the FX8 chips, that's why encoding was so much faster. Unfortunately for the majority of the consumer market that one metric is not enough to change buying opinions.

     

    "And yeah Ryzen is an awesome success"

     

    Yes it is! Ryzen is fantastic! AMD has made leaps and bounds in their IPC and created a chip that's as fast as Intel for half the cost, or less! However, there is something off about the design. AMD's "Infinity Fabric" has serious latency problems and it's slowing down gaming performance which is what a lot of us use our computers for, and that's because AMD wanted games to run on more cores. By having a game run on more than four threads AMD has shot themselves in their own foot. Having one core communicate with another and having threads hop a thousand times a second across that interconnect adds up those 140 ns real quick. Had AMD not done that Ryzen would have been an absolute knockout, but it isn't.

     

    People thought the problem is the Window's Scheduler, it isn't. People thought the problem is software, it isn't.

     

    You can work around the interconnect by forcing threads to stay on one CCX or not have as much cross talk between CCXs but the fundamental problem is AMD created another flaw in their architecture that seriously hurts them. The biggest market they need right now is the gaming market, not HEDT-lite, and they missed that opportunity a bit because you're still better off buying an Intel product unless something can change in the near future.

     

    "not what this thread is really about"

     

    So what is it about?

     

    "just wondering if these people changed their idiotic rhetoric."

     

    Ahh, so you don't like the opinions of others. And suddenly your thread has become what now?

    You might ask yourself again, why you? Well, you've amused me enough to be the first exhibit in my reasoning for not liking people. There's nothing about you particularly, you fit in with the rest of the drops in the ocean. But you're amusing and I'd like for you to stay around for a while, see what else we can pick from your brain. You said that I have an ego and need to mature, and you're correct on both, but not for what you think the reasons are. I'll start with the second. Everyone needs to mature, and you are never done maturing. You're only given a certain amount of time on this rock and you should use it to gain as much knowledge and wisdom as you can. Where you are also correct. However, I am not going to spend every waking minute of my life appeasing people like you who can not show a little maturity in response. So I won't either. It's not petty because I'm not acting like this because of you. I simply don't have the energy to care about you specifically, because then I need to devote that energy to everyone else fairly. So I'm not going to, I'm going to give myself a smile and watch you be you and do your thing. And the second, my ego. You're damn right I have an ego, and I have one for a reason. I have experiences you may never understand. You might have experiences I will never understand. The difference is that I spend my time not making dumb little mistakes in my life where they can be avoided. I don't want to create headaches for myself, it leads to having happier days and a happier forum experience.

     

    But wait, you dislike people, you can't be happy!

     

    Of course I dislike people! Because of my ego. Each day I see people making the same mistakes and complaining when negative things happen to them. You are Exhibit A in my documentation for what I dislike about people.

     

    Steak is good until you cook it too much, then it needs some kindness.

    Have a nice day.

     

    Update 1:

    Sad news, may you find peace where you rest.

    aphexxis.PNG.14ead58e1e3859f716ce4531d2c55561.PNG

  11. This is the review of the Shure SE215, not to be confused with the SE215LTD which is a variant of the SE215 introduced at a later date.

    At first

    Coming from basically using <$40 earphones i did not know what to expect from this. I was utterly disappointed in the how the earphones fit in my ears and how lackluster they sound, i really thought that the sounds quality would have dramatically changed after switching from low grade entry tier audio products. Low bass response, confused mid and highs.

    Which leads to the next point, after a period of 5 months, i learnt how to use the included foam and silicon tips properly to obtain a great seal, the included silicon tips provided provide a balanced sound and as i would like to rate it 7/10 in terms of noise isolation and with the included foam tips, 9/10 in terms of noise isolation. (Medium sized comply eartips are 8.5/10)

     

    After my stock cable was damaged with the right side being faulty, i replaced the stock cable with the FiiO RC-SE1 replacement cables.

    I found these to be more detailed and less warm in terms of audio quality than the stock cables, with slight but noticeable treble boosts probably because of a higher Silver content in the SPC(Silver plated copper) wires.

    However, the micro-phonics on this particular cable are downright atrocious. If the stock cables would have 7/10 in terms of micro-phonics, these new replacement cables would have gotten a 1/10.

    I straight up discourage anyone who gets annoyed easily when music is not playing and the cables rubs with each other. Otherwise, when playing music the micro-phonics can barely be heard and the cable is of great quality and certain to last for a long time.

     

    I am going to try out the ATH E40s in a few weeks time and maybe i can provide a comparison of that when i get myself on them :D.

    This build should mark as low as it should be how a gaming build should at least be like.

    With this build, any game will be playable. Upgrading would be possible.

    The included hybrid drive makes the system overall more pleasant to use with increased boot times similar to of an SSD but without the hefty price tag of one.

    With no upgrade however, this build can last you 1-2 years fairly well.

  14. The 'wonders' of 802.1D... This is just a quick blog to discuss the CCNA level of the process of how switches in an ethernet LAN will elect the root bridge and a few other details.

     

    Firstly, Spanning Tree Protocol (STP) is? Simply, a way to create a logical 'loop free' network in our LAN by blocking specific ports that could cause a frame to loop indefinitely in our network. I'm assuming you have a basic understanding of STP because that would be required to understand the basic root bridge election.

     

    Getting straight into it, when you connect 2 or more switches together they will begin the process of the 'root bridge election' which can change the way frames are sent in the network or even in different VLAN's. Take a look at the example below:

     
    de28d7_c17c0a7dd18045dead4c66ba3bbcbbb9~

     

     

    Imaging we had no such thing as STP, the basic example shown is a broadcast has been sent from PC0 to SW1.

     

    SW1 with basic switching functionality, will broadcast the frame out of all ports except the one that received the original frame, this seems very normal so far. In short story, the switches will broadcast the frame out of ports the original wasn't received on so it will be going back and fourth until someone literally comes over and literally turns the switch off, it seems extreme but remember that the switch will not broadcast that frame out of the port it was received but SW1 received a broadcast from both SW2 and SW3 (so SW1 will then broadcast the frame from SW2 out fa0/2, and the frame from SW3 to fa0/1)

     

     

    So in a short story, STP will block redundant links to stop these frames from looping. You could have the switches daisy chained but that defeats the whole purpose of redundancy and that if we had multiple switches (SW1 -> SW2 -> SW3 -> SW4), if SW3's link were to go down, people connected to SW1 and SW2 wouldn't be able to talk to people on SW3 or SW4.

     

     

    So what is this 'Root bridge election' or what is a root bridge?

     

    When I first looked at the root bridge, I thought to myself does all the traffic need to go to the root bridge before being forwarded to the destination? Because that seems impractical! Of course, it was the first time I've encountered STP and I wasn't 100% wrong sort of... (but close to it!).

     

    The path towards the root bridge from other switches are commonly the fastest (or least cost) which can be changed. The easiest way I would explain why the root bridge is needed would be along the lines of: "The root bridge allows other switches to have a destination to decide which ports to put in forwarding and which ports to block, by default the least cost (fastest path/speed) would be a preferred path to the root unless you manually configure things like costs and priority...."

     

    Traffic will not need to travel to the root bridge first, unless it needs to travel in that direction or is the only way to get to the destination. We will talk about the different port roles and types for STP a little bit later.

     

     

    Bridge Election Process

     

    The bridge election process begins with switches exchanging messages, the Hello BPDU (Bridge protocol data unit) formally known as a configuration BPDU (a lot of people may call it a hello, because it is being sent over and over again like most Hello's in other protocols, excuse me while I refer to it as a hello BPDU for now...).

     

    The Hello BPDU will be used to compare on each side of the link and exchange information such as:

     

    Root Bridge ID, Sender Bridge ID, Path cost to root, Port ID and Timers (MaxAge, Hello and Forward Delay). The BPDU does contain more fields, but these are the important ones for now.. (Protocol ID will be 0x000 for IEEE 802.1D)

     

     

     

    I believe the main focus in the CCNA is firstly focusing on the Bridge ID (BID) and what forms it. The BID is a field in the BPDU which is 8 bytes. Split into 2 parts:

     

    • Priority = 2 bytes (divided into 2 parts: 4bit Priority + 12bit VLAN ID) (interesting fact (2^12 = 4096 VLAN's anyone?)

    • System ID Ext (MAC Address) = 6 bytes

    Without no configuration, we have some default values in our BPDU that are generated on switches. Such as:

    1. Each switch will think it is a root since no root has been elected yet...

    2. Each BID priority will be 32768 (VLAN1 = 32769 etc...)

    3. Hello Timer is 2 seconds default

    4. Forward Delay is 15 seconds by default

    5. Max age is 20 seconds by default

     

    So upon BPDU messages being exchanged, what will happen since the BID priority is the same? If that ties, then it will move onto comparing the System ID (MAC Address) and will always elect the switch with the lowest MAC address as the root as shown in the example below:

     

     

     
    de28d7_9c623d59e9794541a6a023eba9f1ce8f~

     In this example, we see that SW3 actually has a lower BID which then tells us that it will become the root in this election process. Ok so are BPDU's still exchanging after this simple process? Yes of course! BPDU's are actually generated from the root and will be sent down the topology similar to the picture below:

     

     
    de28d7_a06c2efcd0e247fca38911be76230a41~

     

    You can see that the path cost is added to as the basic 'BPDU' is sent down(logically) from the root but where do these numbers come from? STP (1998) has values which I believe you may need to remember for the CCNA exam such as:

     

    10Mbps cost 100, 100Mbps costs 19, 1Gbps cost 4, 10 Gbps cost 2

     

     

    Now that the root election process has finished, that is pretty much all done? You'd be wrong in not wanting to learn more! Since the previous examples don't really show STP's capabilities of making sure the network is loop free, let's add a redundant link in our switched LAN from SW1 to SW. The image has been changed slightly to make it easier to talk from the logical topology view (remember SW3 is still the root!).

     

     
    de28d7_af8aaf26015e48179cfa77bf66e41e19~

     

    So a redundant link has been added and BPDU's have been exchanged but wait... It seems that we understand one of the first values compared in the BPDU is the root bridge ID. SW3 and SW2 will both send a BPDU with the same Root Bridge ID?? Is the switch going to freak out? Is STP going to break? Of course, that would be a poor design if it did but it simply moves onto the next value to compare...

     

    Sender Bridge ID - Is the Senders BID lower than mine? No.... Simply move onto the next parameter. Cost....

     

    SW1 root path cost using gi0/1 will be 4

    SW1 root path cost using fa0/1 will be 23 (because it needs to also add the cost to get to the root from the SW2 gigabit connection)

     

     

    Port Roles and States

     

    After the switch has completed this new election process with the new redundant link, we can move onto the next stage of the STP process. STP defines port roles and states to be used by root and nonroot switches. The root switch will simply put all ports in the designated role and states will be in forwarding mode (FWD), so lets focus on non-root switches.

     

    Every non-root switch must have a root port which essentially is the lowest cost to reach the root switch. SW1 has made g0/1 the root port since it is a STP cost of 4 rather than f0/1 which would be a cost of 23.

    (sorry about hostname, this was issued on SW1)

     
    de28d7_ff6c5aab54e44ea8a94e153f560cc187~

     Because the Root switch will generate BPDU's that are then sent down from the topology, each switch will add the cost on the BPDU before sending it out.

     

    • The BPDU sent from SW3 to SW2 is 0 then SW2 will add a cost of 4 then will be resent to SW1. SW1 will receive it on port f0/1 and will add a cost of 19 creating a total of 23.

    • The BPDU sent from SW3 to SW1 is 0 then SW1 will add a cost of 4 then will be sent to SW2. SW2 will receive it on port f0/1 and will add a cost of 19 (23) which is a worst path than g0/2 to root.

    As you can see in the #show spanning-tree. It also lists on SW1 that interface fa0/1's role is Desg (Designated).

     

    The designated role will be the port that advertises the lowest path cost to a LAN segment. Of course, ties will occur which will result in the BID's being compared and the lowest BID will be chosen. All other ports that are not a Root or Designated will be transitioned into the 'Blocking'(BLK) state as shown on SW2:

     

     
    de28d7_8d61e0173d0b4d6480b9b7444fa61aa3~

     

     

     

    In the next blog on STP, we will talk about STP convergence, 802.1w (RSTP), PVST+, Configuring them all and tweaking STP values such as priority, cost, also I will go into depth on STP port roles and states etc.. I will be replicating this topology with 3 Cisco 2950's instead of using Packet Tracer. (PS, I wrote this on my actual blog but thought I might aswell upload it here, sorry if any formatting issues occur!)

  15. A software without Testing is like a body without soul. Chill... I mean to say that Testing is like you can feel but can not see. Software reliability and security can be check only by the software testing. If you want that your software as per your goal you need software testing no matter either its manual or automation.

     

    But Automated software testing is the majorly using testing services nowadays. Test Automation make your testing work easy to test web and software. It is very useful in case of repeat testing. It will repeat till all the bugs removed. 

     

    Automated software testing has many pros but their some cons also. It is very is for testing proficient persons but hard for non-skilled persons. Automation testing process is quick but the documentation process is very hard. It is good in performance, and better than manual testing but debug script is difficult, procedure is little expensive, little change may cause damage in software.

    Some Pros of Automated Software Testing are like

    • No coding knowledge require
    • Time saving
    • Accuracy 
    • Multi Platform supporting

  16. Loungin was the third and final single released for LL Cool J's sixth album, Mr. Smith. Released on June 25th, 1996, it proved to be a large smash, thanks to the remix produced by the Trackmasters and featuring Total on the chorus.

    The song is, very simply, LL finessing a woman in a loveless relationship with another man. Sampling Bernard Wright's 1985 hit Who Do You Love? (which focused on a topic not unlike LL's I Need Love), its instrumental is still one of the best aged ones.

    An app is an unreasonable amount of work to implement, and aside from push notifications it would bring very little benefit. In the future, following a lot of work (though still a lot less than a full app), push notifications may be supported here without an app (it is now supported by Chrome and Firefox), but it's not something that you can expect to see soon.

    LMG makes money, but the forum certainly doesn't. Making an app that is actually worth having is very expensive, and there would be no return on that investment.

    Aside from the editor, which is an issue, are there any other reasons that the mobile site is a joke?

    All the major desktop browsers support notifications, but the site doesn't support push notifications, which don't require the site (and sometimes even the browser) to be open, and which work properly on mobile.
