    Eigenvektor got a reaction from SenKa in Word 5.1a Not Enough Disk Space Mac OS 9.1   
    I've seen this issue before with older applications that couldn't handle disks that were too large (or rather too much free space). Basically they calculate the free space e.g. using a 16 bit number and a too large value causes an overflow and results in a negative number. So… try filling up the disk first? 😄

    Here's an article that mentions the key points: The technology aboard the Mars rover Perseverance: An inside look
    And, as @tikker said, the mission started over a decade ago. You're not going to use the latest stuff that just came out, because the would mean redoing all the tests and validation steps beforehand. If you discover a critical flaw in the CPU after launch, you can't just swap it out for a different one like you could do here on earth. So you're going to make absolutely sure that stuff you're working with has been tested and tested again to be as reliable as possible.
     
    This. Some high energy particles you can't really shield against plus you'd need a (literal) ton of shielding. All of the extra weight means you lose out on other payload stuff. Shielding doesn't help you do science, so it's not something you want to carry along unless you absolutely have to.

    The rover mostly just has to collect data. All of the heavy processing will happen on Earth.
     
    And yeah, it does have different requirements:
    Be as reliable as possible Use as little power as possible Be resistant to space, radiation etc. Using bleeding edge technology is no good if you need something that is ultra reliable, because you haven't had decades to fix all the kinks. And smaller process nodes are much more susceptible to stuff like radiation and high energy particles. You don't have a magnetic shield on Mars like you do on Earth.

    Eigenvektor got a reaction from Luxzio22 in Want to start a blog with wordpress.org, don't know where to start   
    A server is simply a computer that provides some kind of service. The number of components (or applications) you need to install to provide that service depends on what exactly you want the server to do. In the case of Wordpress that would be the aforementioned LAMP. Wordpress is an application build on top of other applications, so you need to install them to be able to run Wordpress.
     
    As I said, LAMP is short for Linux, Apache, MySQL, PHP. I mainly mentioned this in case you find that term somewhere, so you know what it is. Sometimes tutorials will simply say "you need a LAMP environment", because it's a fairly well known acronym.
     
    Linux is the operating system everything gets installed on. You could also use Windows, but most hosters want more money for that (due to licensing costs). Apache is a web server, needed to accept requests coming on over HTTP(S), process them and then send a response (i.e. the contents of your blog)
     
    MySQL is a database. This is used by Wordpress to store e.g. your blog posts and user accounts. PHP is the programing language Wordpress is written in and the "runtime environment" needed to run its code. Apache needs the associated plugin installed to be able to run this code during the processing step, so Wordpress can interact with the database and generate HTML based on the posts it find in the database.
     
    Maintaining a blog can be fair amount of work, so you don't necessarily want all of that technical stuff on top. If you have a hoster that provides all of this for you, ideally you don't need to know/learn any of this. You just sign in and start writing and let someone else worry about the technology behind it. Of course you still can, if you want to, but you don't have to.
     
    Definitely doesn't hurt to check what exactly the hoster provides for you though. Do they take care of (security) updates? Do they take care of backups? How can you restore your blog in case the site goes down/is hacked etc.

    Wordpress is a web application. To host it yourself, you need a server somewhere on the internet. This server needs a host name (aka domain name) and (preferably) a valid SSL certificate for HTTPS. You want HTTPS so sign in is encrypted.
     
    The server needs an operating system (e.g. Linux), a web server (e.g. Apache2), a database (e.g. MySQL) and PHP installed. This is often referred to as a LAMP server (Linux, Apache, MySQL, PHP). You could possibly replace Apache2 with nginx and MySQL with MariaDB, but it's probably best to stay with Wordpress defaults if you don't know what you're doing.
     
    You can find instructions on their website: https://wordpress.org/support/article/how-to-install-wordpress/
     
    If you don't know what you're doing, either find a hoster that offers both a domain name and Wordpress out of the box, or ask/hire someone with experience to set it up for you. I think you can also host on Wordpress and use your own host name for a fee.
     
    You shouldn't need to know any HTML/PHP to get started with Wordpress, but you should know a little about servers and keeping them secure if you want to self-host. Hosting on Wordpress has the benefit that they will take care of updates and backups.

    Eigenvektor reacted to Mark Kaine in What are the equipments those are needed to repair graphic card?   
    soldering iron, reflow machine, parts, lead (free) lead... 
     
    That'll be about 20k $ if I'm not mistaken? 
     
     
    I would have thought that too, but then I learned there are parts, like the VRAM where an iron doesn't cut it - because there's no soldering points on the back side of the card, hence you need a *very expensive* reflow machine, technically.

    Eigenvektor got a reaction from Middcore in I finally got a RTX 3080 in a laptop   
    Which contradicts your initial statement that there is no chip shortage for big companies. You managing to buy a laptop with a high end GPU doesn't proof or disproof anything. Governments getting involved to assess/address the situation is.
  8. Agree
    Eigenvektor got a reaction from Radium_Angel in What are the equipments those are needed to repair graphic card?   
    You'd need:
    The knowledge/skill to identify the broken component An appropriate spare part A soldering iron and a (very) steady hand But as @Albert F said, depending on what exactly is broken you won't be able to repair it even if you have the skill. Either because you can't buy the component separately and/or because the cost of diagnosis and repair is higher than the cost of a replacement card.
  9. Agree
    Eigenvektor got a reaction from wkdpaul in I finally got a RTX 3080 in a laptop   
    Big manufacturers have contracts in place, so they get priority over individual consumers. Nothing suspicious about that. The mobile 3080 also isn't the same as the desktop variant, it's a cut down chip.
     
    Doesn't mean HP doesn't feel the silicon shortage as well. Buying a single (premium/overpriced) laptop doesn't exactly tell you how many laptops are available overall and how many customers are going to wait a long time for theirs to be delivered.
  10. Agree
    Eigenvektor reacted to Albert F in What are the equipments those are needed to repair graphic card?   
    Usually when graphics cards die they go straight into the trash can. If it is a blow up capacitor it takes soldering equipment and a bit of skill in this branch. If it is the graphics chip it's D.A.G (Dump it And Go), you cannot really repair those.

    Eigenvektor reacted to Middcore in I finally got a RTX 3080 in a laptop   
    No, we're calling it a conspiracy theory, because that's what it is. An assertion of a malevolent plot by covert actors unsupported by any evidence. 

     
     
    There are no merits to argue. 
     
     
     
    Ah, "dO yOuR oWn rEsEaRcH," the mantra of anti-vaxxers, flat-earthers, and people who believe the world is ruled by reptilian aliens. I guess by comparison ranting about GPU manufacturers is pretty harmless, anyway. 
     
    BTW, if you were willing to blow over $3000, for that price you could have just bought a real RTX 3080 (as opposed to a crippled mobile version) from a scalper, built a desktop around it, and gotten much better value and performance.

    Eigenvektor got a reaction from MrDBD in What’s the smallest SSD possible?   
    Do you want the drive to be usable in combination with a regular operating system?
     
    I that case, I think you may be limited by the smallest addressable unit for storage devices (a "block"). The smallest one supported by modern operating systems is a 512 byte block size. You also need a little room for the file system's metadata and metadata for each file (e.g. 1024 byte on NTFS). So you'd probably need a couple of kilobytes to make it usable in a practical sense.
     
    If there's no such limitations then theoretically you could go as small as a single bit, as others have mentioned.

    Eigenvektor reacted to Archer42 in Chkdsk says "Free space verification is complete". What to do next?   
    Worst decision ever. A way to damage/destroy data even further, making it completely unrecoverable.
     
    What you have to do each time you are trying to recover data is, first of all, create full hdd image. Then depending on circumstances you can either work with original hdd (if it is not broken/damaged) or create a copy and work with it (working with broken hdd makes no sense as it is huge waste of time).
    There are different tools which can be used in such cases to try and fix partition table/filesystem or extract whatever files are there, like testdisk for example.
    But again - you never write anything or run any tools on hdd before you've imaged it.

    Eigenvektor reacted to Mling in Why is my ram full   
    You do have a lot of applications running. Click on performance, then click on memory. I'm guessing the cache value will be high and if it is there is nothing to worry about. Also click on resource monitor and see what that says.

    Eigenvektor reacted to porina in EU to start with a "Digital Euro" within 5 years   
    I'm also struggling to see the point in this "digital euro". What advantage does it offer, or problem solved that can't be met with existing means? Existing banks and credit cards already serve a large part of that, and there are some loadable cards for those who don't want to tie to a bank.
     
    As a cash alternative, the cost to implement another parallel infrastructure on top of that would be massive.

    Eigenvektor reacted to Master Disaster in Want to start a blog with wordpress.org, don't know where to start   
    To add a little to ^this^
     
    The vast majority of hosts will offer Wordpress as a preinstalled option (or at least give you a way to auto install it with a few clicks).
     
    By far the easiest way to self host is by using Docker. I haven't actually looked but I can almost guarantee there will be a container with everything inside, presetup and ready to deploy. I've found full docker images for things MUCH more obscure than Wordpress.

    Eigenvektor reacted to guitargirl15 in I want to run my program (java) on cmd, but an error occurred.   
    JDK should include runtime. Also, you don't need to 
    import anything for this particular program.
     
    I would assume there is an older version of the JRE installed along with the new one that came with the JDK, and the system is defaulting to that one for running compiled Java bytecode, even though it is using the new JDK for compilation. 
     
    You can check Programs and Features (under Control Panel) to see if there is an old version of the JRE installed. If there is, you can uninstall the old one (assuming you don't need it), or follow this StackExchange answer to specify which version of Java you wish to use.
     
    Compiling Java programs via CMD should work just fine even if Java is installed on the C drive, the problem here is likely multiple versions of the JRE.

    You could enroll your phone with an MDM (e.g. Android Enterprise fully managed) use it to only allow the apps that you want and then set a random password on the MDM so you can never modify it ever again 😄
