  1. I regularly go lan-parties. anything wireless becomes a messy pile of s**t there. Way too many sources on 2.4ghz, headphones, mouses, keyboards, the sorry piece of WiFi under all that, the neightbours using same wireless item and getting their input and vv and whatnot. I don't think "lightspeed" will work much at those shitty conditions.

    No Dollar Wasted PC Build Guide

    Ehm, @mariushm , you missed some... static discharge works both ways. Touching ground can charge or discharge you with an amount. The idea of using a wristband is to be connected at all times to keep the charge DIFFERENCE as close as can be at all times. You touching a grounded surface can discharge you, or charge you, doesn't matter, it's bout the difference of charge between you and the electronic component you're working on, so you charged or discharged, but the electric component will be a different charge anyhow. This is why the wristband with wire is connected to the antistatic mat. The antistatic bag does give off the charge, but it basically insulates the content from external influences. Once you grab the component.... it's charge will be equalized with you, Every time after that that you touch ground and the component again, it will have to re-equalize with your charge. As for the 1 megaohm resistor between you and the mat, that will invite charges to go through your hands instead of via the wristband off to the mat. I've set up a lot of workplaces for this, generally you better use a low value resistor between you and the mat if absolutely needed, couple kiloohm's at best. Only exception is when you work with live high voltage equipment... you don't want to become the pathway to ground then...

    The ESD / Antistatic is useless as shown there. You as a person being directly "grounded" means that the anti-static mat below on the desk isn't and that the motherboard on top of the box for sure is NOT as well. The ESD wristband should lead to a connector on the anti-static mat and (often) from the other side of the mat to the ground THROUGH a 1 megaohm resistor. Why the resistor? Because if some is put on it with a high charge, the 1 megaohm resistor will slowly dissipate the charge to protect the equipment. Also, any charge coming from ground is also attenuated, because there is other equipment on the ground connected, you'd gain charge from it if not through a large resistor. The idea is that it's all at the SAME charge (the difference in charge is what the "static" electricity is making it flow). Basically you have in this video a different charge all the time because you're wrongly grounded. So in short: [your wristband] ----> [Anti static mat] ----> [1 megaohm resistor] ----> [ground connector at socket] Sometimes a floormat is also being applied for higher sensitivity.Those are connected commonly together before the resistor. If multiple workplaces have to be setup, those should all be connected together so no one can charge someone else due having different charge. Also, it does happen that the ground in a socket is not connected, I've had issues in buildings where they put 20 cm cable of "ground" in the pipe, but didn't connect it through.... so that needs to be checked.

    Windows 7 On UEFI

    https://blogs.technet.microsoft.com/askcore/2011/05/31/installing-windows-7-on-uefi-based-computer/ Quote from it: Note: One of the common issues we see is that users try to install X86 version with UEFI enabled in the bios. X86 does not support UEFI so you would have to configure the machine for Legacy boot to install X86 versions of Windows. If you do try to install X86 version setup will run but on the 1st reboot you will get BIOS error similar to “No bootable devices –Strike F1 to retry boot, F2 for setup utility. Press F5 to run onboard diagnostics” So that means you MUST run a x64 version of Win7 on it, but the 2GB ram on it will not be enough for it to run properly imo. You'd need to expand / replace that to at least 4 GB ram, but with that expense, i'd consider to look for 8 gb ram for it. (as a follow up on our convo on discord)

    Wipe Any PC in 2 Minutes!

    Yeah, correct. In a FAT (8/12/16/32bit) partition its stored in the FAT (File Allocation Table, often 2 copies on a partition depending implementation/version) In a NTFS (New Technology File System, many versions over the years since Windows NT 3.x) partition its stored in the MFT (Master File Table, can be multiple parts over the drive, has journallling, tiny files that are smaller than I believe 4kb will be stored inside the MFT itself instead of outside with a pointer) And so every filesystem has its own "table" or system with where files are being located and managed with. Seems like somebody didn't do their homework writing for the video. The point of that key is to wipe the entire drive, which includes the partition table and the partitions with their filesystem on it.

  7. You're mostly right, such security will only be there if you'd use a VPN along with it, but most VPN's will require/recommend that you use their DNS along with it... If you configure it locally on windows, it will override the router's configuration that it distributes. The router responds to the client's DHCP requests for an IP configuration. The client does NOT have to take that whole, it can choose to ignore 1 or more parts of that configuration. (mostly because windows doesn't need it, but for example a BIOS network boot need different information for knowing where to get boot images etc) ================ Aside from that, the load times is only influenced if a website has a lot of different domains to load, and only minimally. For once the IP is know, it has NO influence on downloading resources (script, images, whatever the browser or service you use needs). Its nice and all that the IP is known to the client (read browser or other application) knows a tiny bit earlier the IP, but then the work just starts, and the browser then has to start requesting the webpage, which consists of dozens of files (JavaScript, images, CSS, videos and whatnot). Those ALL depend on the server(s) hosting those on download speed, and only at a certain point the browser will start rendering the website for having enough data to do so. Along with that. a DNS cannot know what page you are visiting on a website. It knows you looked up "failbook.com", but that's it. it doesn't know if that was requested because there was a "like" button on a random site that was looked up, or that you visited failbook. With some careful trend analysis they might be able to find out what someone visited. To me, a DNS change has various reasons to consider vs whatever is default at that point: - Is the current DNS being attacked often by DDoS attacks? - Is the current and/or proposed DNS stable/responsive within reasonable times (under 0.05 sec or some) ? - Is the proposed DNS less or more censorized? (ISP's in-country DNS vs for example Google's DNS) - Is the proposed DNS providing more features? (secure encrypted dns requests, privacy, options to select or choose, manual adjustments, etc) Speed of DNS is only secondary, the domain is already been looked up before you lift your "Enter" key anyhow.
  8. Ehm... how to start this, some concepts given out in the video isn't correct. Windows will query only 1 DNS. The Alternative address given will only be used in windows if the primary one didn't work at boot of the system, or a LONG time after the one its using to try the other. Its not a "dead and instant rollover to alternative" approach. for clarification, windows will start looking up the IP like this: - Browser will check if it already has connection or recent connections made to it (dependent on browser). - Query the hosts file (http://winhelp2002.mvps.org/hosts.htm READ b4 doing any) - Query the DNS caching process in Windows. - if all those didn't produce it, the at boot "selected" dns will be queried. - After x time of failing to get an answer, it will finally turnover to the OTHER dns provided. That time will be more then half an hour. Yes, that means if a DNS fails that you currently use, it will take over half an hour before you have internet again, or you have to restart your computer. As for using this particular DNS... I prefer https://www.opendns.com/ where I can put on some security features and configure added manual domains and block domains of my choosing via their configuration panels etc.

    PC shuts down when playing specific games.

    In order of most likely first: Try memtest86+ http://www.memtest.org/ (make a usb boot stick with Rufus and boot from it, and let at least a full pass go over it. if errors found, try reseating memory into motherboard and test again. What wattage is your PSU? If a low wattage like less then 600 watt PSU, your Motherboard could be starving to deliver the 65 watt power over the PCI-E bridge to the card. if say 650+ watt, then it could be that power delivery by the motherboard has issues (see point 4), due capacitors being bad etc. e Do you have windows 10? if so, download and install the newest driver (again). every "mayor" update M$ is messing with the drivers of NVidia, and problems ensue. Can you test the video-card in another computer with the same game(s) that gave issues?
  11. Hmmm, direct answers to direct questions... Define first "valuable" in this context for yourself: - Valuable to whom? LTT? the other members in general or those with technical or non-technical (!?!?) questions/problems/subjects etc? - What value? Forum to become better by your posts, and in what way? Informative/helpful? fun? keeping discussions flowing? - Role? is it some "badge" you're after? In generic its just: think before you write something, has your point already been said, does your input alter other replies on a subject enough to warrant even posting? A lot can be chalked up onto "mindless noise". I've been there, I've been on forums where I've had over 20k replies. The number doesn't mean any, it just means you've been this active on this forum for so much since you started. So, only you can define what more valuable means. Each of the different answers you could make up for that has their own path to follow. The way the question was formed was more a hidden quest for making sure that the time you sunk into it was for some "use" to something is my guess. To that I can say: you could have used your time in other ways, so make sure that what triggered you for each of your next replies, is some you deem worthy of a reply.

    How Dolby Cinema works. Pretty cool with 6 different color lasers, almost 100 kilowatt in audio etc. Tip for tests: Full audience, sit in outside corners or center. They say it doesn't matter, but it does. But if you sit near center, the experience is FAR better then any other cinema tech (IMAX etc) Contrast ratio is a lot higher vs IMAX (Imax requires reflective surface due it being polarized, Dolby cinema is standard projection screen) IMAX you need to sit horizontal with the glasses, Dolby cinema you can have your head tilted without problems, for its not polarized, its chroma-keyed (or whatever its called)

    HARD DRIVE Mining? This is getting ridiculous...

    He says higher temperatures is a problem to hard drives, its actually not: Usage isn't a problem either. quote: other notable patterns showed that failure rates are indeed definitely correlated to drive manufacturer, model, and age; failure rates did not correspond to drive usage except in very young and old drives (i.e. heavy data "grinding" is not a significant factor in failure); and there is less correlation between drive temperature and failure rates than might have been expected, and drives that are cooled excessively actually fail more often than those running a little hot. https://www.engadget.com/2007/02/18/massive-google-hard-drive-survey-turns-up-very-interesting-thing/ So keep your drives in a nice warm place
