  1. Cable testers are fun. Though, the capabilities of a given cable tester can vary greatly. Some can do simple stuff like check for continuity and see if the wires go where they should. Others can test the isolation and see if the cable has some flaw, like a wire pinched in some housing or the like. (These testers can be expensive.) Some will current test the cable, by sending a good amount of amps through it and see how much voltage is dropped over it. (Not always a practical test, especially for long cables.) Some can test data rate by simply clocking data through them
  2. Seems like a fairly decent phone. Though the lack of a headphone jack is a major disappointment. Though maybe they will make an alternate case in the future. But until then I will continue rocking my 8 year old Sony that magically works despite literally falling apart by now... Though, personally I would have gone all torx screws, since philips ones are fairly easy to round out the head, especially these small screws. And one rarely needs to apply force to do such. In other words, I suspect that people will get more problems in regards to broken screw heads than much else. However,
  3. A lot of AI workloads can be made far more efficiently with regular code. There is however certain things that an neural network is the easier solution compared to making code. (Generally anything that is sufficiently complex for one to not logically figuring out any suitable way to approach the problem logically. This simple "check" is however not indicating that a neural network is suitable for the application, the programmer/development-team can just be dumb/unskilled and not know how to approach the problem logically to start with.) However doing detection of people in a room i
  4. The time it takes for an LED to burn "out" is mainly dependent on the temperature of the LED itself. Warmer temperatures makes them die faster. And yes, the time it takes for an LED to die also follows the magical "twice as fast for every 10 degrees C increase in operating temperature." Though, this gets whacky when looking at an array of LEDs sitting tightly spaced to each other on a rather lack luster thermal conductor. Since the actual screen itself is typically built on a sheet of glass and glass isn't an all that great thermal conductor, so sucking out the heat is likely not a
  5. There is far more than just AVX to be fair. Though, a given application can be compiled for CPUs that even consider SSE1 as a new fancy extension. And this is a thing that a lot of CPU manufacturers have to consider, when a new feature gets made it rarely gets used due to default settings in most compilers and such. So running benchmarks on new CPUs rarely gives a good picture of the true uptick in performance, only as the software gets updated to make use of the new instructions will it actually impact performance as the manufacturer had planed for.
  6. I will try to keep myself short.... But having studied computer architecture design for over a decade makes one opinionated when it comes to oversimplified videos like these. First off, IPC as a term is a bit stupid at the moment. Since it conflicts with the term IPC. Ie, Inter Process Communication, a topic that is fairly central to more multi threaded workloads. The instruction rate per cycle could use another term instead of Instruction Per Cycle. I think IR for Instruction Rate works better, since it isn't conflicting with anything else in computer architecture desi
  7. The "we might already need the 64 GB" part I can relate to. Upgraded my main rig to 64 GB for that reason myself a while back and have room to double it if needed.... Though, a second reason I went higher in memory were so that I could tell Windows to stop using the OS drive as additional memory, since it really bogs down overall system performance. (Don't know why windows decides it is a good idea to do even if one doesn't even use 6% of the memory... I can understand if one is up above 60% or even 80, but it always migrates "inactive" stuff out from RAM...) Though, seems lik
  8. I have long been curious to the pros and cons of flash storage, especially in long term storage applications. I will give a quick heads up here in the beginning that I will get technical in this little write up. Due to the way that a Flash cell stores data, it is inherently not persistent long term. As I explained here: This means for an example if we put a USB thumb drive or SSD into a time capsule for even 20 years, it is likely fairly corrupted or even empty by the time it gets uncovered. (There is also a difference depending on the exact manufacturing
  9. VGA weren't a standard in the 60's, took until 1987 before any computer on the market supported VGA. But the large mainframe computers could have a fair bit of IO, and at times better IO expandability than even a lot of modern systems. It weren't all that uncommon to have systems with 10's of hard drives, or whole office floors of terminals interfacing with the system all in parallel. And to be fair, the idea of mainframe computers is still around, all though not that common even in more computer heavy industries.
  10. I work in industry, connecting with Ethernet to various production equipment is fairly common. Dragging around USB to Ethernet dongles is not all that practical in a lot of cases. A dedicated Ethernet port is generally preferred. It isn't really about file sizes or transfer rate, most industrial equipment uses 100 Mb/s Ethernet or slower, the wire is more for the fact that WiFi is fairly "abhorrent" to deal with in an industrial environment. In short, I have a somewhat niche application, but a modular laptop is also something that could relatively trivially scale to various niche applicat
  11. To be fair here. The framework laptop is a very nice concept. BUT, I honestly hate that the modules weren't 1cm wider as to ensure that they could have 2 USB type A ports on them. Secondly, the base machine should have had a type C port on each side so that we don't have to waste a module on something that we Must have for the thing to even work in practice. Minor gripes I have with it is the lack of a Scandinavian keyboard layout, but they do promise a clean ISO one in the future (and I own a laser cutter and can engrave my own prints), so this is only a minor gripe
  12. I would more worry about congestion as far as wireless bandwidth and all the background heart beats keeping the network up and running "smoothly" being the main drawbacks. Being alone in the local area, then wifi is wonderful. Add a handful of devices and suddenly the experience is a lot more lackluster. Even if those other devices aren't actually doing anything. And this is why I at least try to run as much as possible over network cables, especially things that aren't going to be moved all that often, like a TV, game console, IoT devices, or computers in general. And having
  13. Personally I have never really enjoyed wifi as a technology to be fair. Yes, it does save a lot of cable clutter at times, but to be fair. Cables are way more reliable in my experience. All though, wifi is nice for certain things, like phones, laptops and other portable devices. But anything that is more permanent tends to benefit from a wired connection. (all though, I can see how some "upgrades" can be easier if using wifi instead of wires, like Linus' thermostat situation. All though, I myself would have just pulled out the old wiring and put in new, considering how th
  14. Editing the content of webpages for fun is something I have done more than once. Though, usually for learning how different webpages are composed, HTML coding can be fun after all... And in regards to "hidden" content on webpages, yes, some webpages do hide the content on the client side.... Some websites though do things correctly and don't send over the content, or only gives a short preview. Though, I have stumbled over the occasional website that were at least making an attempt by using a bit of scripting checking if the end user is logged in or not before load
  15. Pencil manufacturers have used vertically stacked graphene sheets for centuries without including it in their marketing! (this is a joke, but graphite is stacked layers of graphene, so it is actually true.)
