https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.
For updates refer the kernel tree: https://git.kernel.org/…/ke…/...

Pc wouldn't boot. Went to the service center.
The guy at the shop : what's the problem?
Me : pc won't boot, just starts beeping
The guy : I see. It could be a hardware or a software problem.
Me : (trying to keep a straight face) oh?
Him : oh yes... It's always either a software or a hardware problem.
Me : thanks I guess?9 -
So, I'm programming a control system for a prototype aerospace vehicle. You know, the stuff that needs to work to prevent falling out of the sky.
Anyway, test day was today (was -- not anymore). Wiring all the electronics, everything is actuating and works well. Except for one part, a little thruster for stability.
I spent hours - literally, fucking hours - trying to fix the problem. Wrong address? Wrong syntax? I had absolutely no clue what was wrong. Queue the hardware guy, $stupid:
$stupid: "How have you not got it working yet?!"
$me: "I don't know, everything I'm trying isn't working. I've spent hours digging through this code and nothing is fucking working."
$stupid: "Well have you set it up for the new thruster?"
$me: "What...What new thruster?"
$stupid: "Oh, the one we installed this morning, did noone tell you?"
WHY WOULDN'T YOU TELL ME THIS?! COMMUNICATION 101!6 -
So. A while ago I was on OkCupid, trying to find the Pierre to my Marie Curie (without the whole brain getting crushed under a horse carriage wheel obviously) and I decided the best way was to have my profile lead with my passion for technology. It turned out pretty unique, if I do say so myself.
At the end of it, I amassed some interesting and unique messages:
- A Java pickup line (that I never responded to. Yes I'm a very basic Devranter)
- A request to turn the man's software into hardware (to which I politely informed him that this was scientifically impossible unless a reader proves me wrong)
- Another impossible request to turn his floppy disk into a hard drive (how outdated too, why not HDD to SSD for faster speed amirite? That was awful don't mind me)
- A sincere request to help troubleshoot a laptop (Honestly I would've helped with help requests but this is a dating site...)
- A sincere request to help debug a student project followed with a link to a GitHub repo
- Another sincere request with studying for a computer exam
- And lastly, my favourite: a sincere job offer by a guy who went from flirtatious to desperate for a programmer in a minute. He was looking for *insert python, big data, buzzwords here* and asked me for a LinkedIn. I proceeded to inquire exactly what he wanted me to do. He then asks me to WRITE a Python tutorial and that he would pay a few cents per word written so he could publish it. Literally no programming involved.
Needless to say I went to look elsewhere.26 -

I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

I got a used computer case in a second hand hardware store and it still has the sticker with the specs of the computer they wanted to sell it with on it. It was going to be a moderate to shity pc. I built an absolute computing monster in it (i7 6900k, 32GB ram, 23TB storage). I like having visitors over and telling them this is the primary computer I use to do my high particle count fluid simulations and little bigdata projects with.

Never thought I will be hired by Chinese software/hardware company located in NYC to code in languages I don't know so well. Instead of lying and saying I know everything about C, PHP and SQL, I said that I suck pretty much at everything, but I'm a quick learner and will study day and night to catch up with their practices. Now I see they have no regret about me, but I still suspect them in hiring me because there is another guy who is Russian too and we all communicate well. Our current squad is 17 Chinese, 2 Russians, 1 Americans. Guess what, I learn Mandarin quicker than PHP. Sometimes a small lie is OK, but sometimes honesty is better.3

Our software uses a lot of video/audio hardware. But this hardware goes away when we deliver to the customer.
So everyone was asked to think of a way to be less depended on hardware.
I thought of a very clever idea and I told it to two senior software engineers who both saw much potential in it.
I've only worked here for close to 2 months. And I feel like this is a major contribution if they'll use my idea
Next week at the brainstorm session I'll have to present my idea (informal meeting)
I'll make an update when I know more3 -
As a software engineer, I decided to participate in a hardware Hackathon. I went in not knowing much about the subject, but by the end of the weekend, we made a fully functioning (somewhat janky) jacket that could roll up or roll down its own sleeves depending on what your body temperature was (inspired by Back to the Future 2). We also created a remote, so you could control the length of the sleeves as well. It was the most off-the-wall, ballin project I've ever been a part of.10

My laptop started making faint high-pitched noises - I hope I misheard and it's actually just some coil singing inside the power-supply and not one of the disks/something else - also, I seem to have dropped 4GB of RAM suddenly where there should be 8GB.
(Also, I should really wipe the messed up dual-boot still residing on disk from last semester and replace it by a fresh arch-only install. (No time and joy in debugging that right now.) Probably something for tomorrow evening.)
The device is ~8 years old by now and starting to fall apart - nothing duct tape can't fix - but I'm somewhat worried about the rest right now. D:
Meh, I really need that laptop during the next two weeks, I just hope the hardware doesn't die on me in the meantime because I can't wait for an order to arrive, let alone afford some cheap replacement.11 -
devRanters, especially the linuxers, unusual request/question, especially coming from @linuxxx!
I just found two very old netbooks which still contain windows xp (I didn't even know I still had them at all) and I'm obviously going to turn them into Linux netbooks.
Does anyone know any good looking linux distro's that run well on low-end hardware? This is not my specialty since I either deal with servers or higher-end computers :).
Please pass me some suggestions!55 -
I'm a web developer and know jack about hardware. My wife's personal laptop was going very slow so decided to upgrade to a SSD. How hard could it be?
Turns out to be very fiddly trying to disconnect and reconnect 4 ribbon cables. To get to the HD and replace it.
Restarted laptop and thought it was all good, but only certain keys worked and the mouse pad moved but didn't click?!?
Had to take it apart and reconnect twice more but now it's fully functioning once again.
Sticking to software in future. Massive respect to hardware specialists!6 -
A PCB I designed on the job over the last weeks shipped today! A benefit of hardware is the haptic element you have at the end of the design process - you made something touchable. (I am proud.)
Also, errors made earlier in the design process are permanent now. But other than on my software my design got reviewed, so I'm optimistic it'll not contain many if any.
I'm on vacation right now for moving stuff but I'm looking forward to do the "pick'n place" on monday. Soldering manually is quite relaxing for me, you should try it, too! ;)
In other news, I'm no longer sleeping on the floor in my home-office while the paint is drying in other rooms.
I already moved the most of my stuff - books and tech equipment are the worst - and I moved my furniture yesterday.
My new roommates are considerably quieter and my sleeping rhythm is slowly shifting back to normal.10 -
Atother story about PC hardware and being... Not so careful.
A friend complained about his PSU fan being too loud. I said "well, maybe bearings are dying already".
The next day he messaged me and asked to suggest a new PSU. Ok, I threw him some links.
Leter, he told me what happened:
He decided to clean the PSU, because he thought the noise could be because of dust. So he turned off his PC and removed PSU cover with a screwdriver. While doing this, he accidentally hit the circuit board itself. Then "Puff", black smoke and smell of sth burning. Turned out he didn't switched the PSU off. Luckily, the screwdriver handle was rubberized. I'm glad he is alive ._.1 -
Hardware of laptops today.
Displays: Glossy screens everywhere. "Hurr durr it has better colors". Idgaf what colors it has, when the only thing I can see is the wall behind me and my own reflection. Make it matte or get it out.
Touchpads: Bring back mechanical buttons. Haptic feedback dying with touchscreens/surfaces is a tragedy. "But we can have bigger touchpad area without buttons" ...why? the goal shouldn't be 1:1 touchpad vs. display ratio. It ain't a bloody tablet.
Docking stations: Some bright fucker figured out that they can utilize USB C. That thing keeps falling out with slightest laptop movement disconnecting all peripherals (guess why microUSB had those small hooks?). Also it doesn't have sufficient throughput, so the 5 years old dock can feed 3 full HD monitors just fine and the new one can't.
Keyboards: Personally I hate chiclet. And it's everywhere, because "apple has it so we must too". But the thing I hate even more is retardation of the arrow keys (up and down merged into size of one key), missing dedicated Home/End/PgDwn/PgUp buttons and somebody deciding the F keys are not needed and started replacing them with some multimedia bullshit.
My overall feeling is that this happens when you give the market to designers and customer demand. You end up with eye candy and useless fancy gadgets, with lowered ergonomy and worse features than previous generations of the same hardware. My laptop dying is my daily nightmare as I have no idea with what on the current market I would replace it.5 -

A few hours ago I decided it was a good idea to to clean up my keyboard. I did so and took a walk leaving the keys to dry.
After I came back I hoovered the -board and decided to put back the keys. I started with the special keys since they were the easiest to find (and some required a metal thing).
Now, I was quickly made aware of something that I had never known nor noticed before. Bear with me here as I'm not a person that cares too much about hardware unless I need to. (Hardware here meaning stuff like mice, keyboards, headsets, and stuff like that). But I learned that
Not all keys are the same size. They look really similar to someone like me. But I manned up and put the keys back.
A little under 1.5 hours later and I now posses a keyboard that is in uncanny valley. It doesn't feel like it though, and it shouldn't be that big of a problem since I never look at my keyboard anyway.
Messaged one of my m8's about and this was his reply
"nope
one kind per row
usually says the row on the underside"
Now fantasize about the elasmobranch fish which is characterized by a cartilaginous skeleton of which I am the proprietor at what he said. I pulled a key out and, sure enough, "C28 R1".
Now I am not sure about the 28th column, but it did fit in the first row.
Fuck me

Client: i'd like to develop for this particular device named the hololens. And i want 2 of those to communicate over LAN as well (holo lense specific data)
Dev team: If you can provide us with 2 holo lenses to try some stuff out, we can do that.
Client: Well i only got one but i need that for my presentations to my clients. Can't you just research something and make it happen without the hardware?

When working with hardware some mistakes can be literally painful. Thankfully this was all during undergrad and I'm only around computer hardware now lol.
>Misprogrammed a software kill switch so a sensor that should not have been sending data was actually sending data which caused the system to activate a piston that went WHAM! into the face of a teammate working on replacing some part of it...
>Misprogrammed a controller so it drew too much power from the supply and the puny supply wires literally burst into flame and fell across my arm.
>Spun a 9000rpm CNC spindle the wrong way and caused an attached screw to go rocketing upwards instead of downwards and almost break the (pretty expensive) thing (uh...we were trying to use it as a power screwdriver essentially but I set the rpm to about 100x what I wanted and the direction wrong so yeah).

This freaking laptop.
The WiFi randomly stops working -- and by that, I mean the hardware is no longer detectable, let alone functional. It simply disappears on boot, even from dmesg.
The same happens with audio and bluetooth: on some boots they simply do not exist.
The power usage is also ridiculous: the battery dies in about two hours, and it gets soo hot. Toasty wrists unless I use my tiny bluetooth keyboard ☹ So I need to fiddle with powertop a bit more.
nVidia drivers are also a bloody pain, and having two graphics cards this is even more difficult to set up. I still haven't managed. (nvidia-driver, bumblebee, optimus, official driver messes, manual xorg configs, ...). So I have a beautiful 4k built-in display running at 4-18 fps, and a non-functional 4k external. That's fine for now, but >.>; frustrating.
In better news! I just managed to get the sound to work by backporting the new 4.19 kernel (yay!) -- I have never been so happy to hear an ad. but fixing the sound killed my bluetooth. (The `bluetooth` utility reports the adapter is present, but nothing else can seem to see it 🙄) So now I'm going to have burning hot wrists all day and want to cry because terrible sweaty awfulness.
Just. It's frustrating.
It's fast, though.

A classmate's earphones once stopped working, I went to go look at it. After a bit of tinkering, I said, "The speakers on these are toast, you'll need a new pair." Then, some random kid grabbed the tablet mind you, and not the earphones, played in the settings, and said "Fixed." I then told them, "This is a hardware issue, not a software issue." What's worse? Some people said "So, software and hardware are the same thing."

Damn maintenance windows. I mean, I get that the SaaS product my boyfriend works on can't go out in the middle of the day. But he just spent weeks on a business trip, with an absolutely mad sleep schedule because he's redesigning their data center (or something. Don't ask me, it's a hardware problem...) and now he's finally coming home today and I'm super excited but all he's going to want to do this weekend is sleep. Even though I'd love to spend Sunday going to this yearly event, or finally getting another round of DnD in (everyone else in the group is available). But nope. Bloody all-hours work is taking away his (and thus my) weekend too.2

Working at my company for one year with two old 20 inch monitors. My boss asked my what would improve my productivity. I said give me two fucking huge and nice monitors. I got the approval that he ordered for all of us new monitors.
One of the support guys told me the we will get the monitors today. Yeah but that was two weeks ago..
Now all of us are only taking about new monitors.. kinda funny that you can get excited for hardware so easy. Love the IT <31 -
Why is it that software has gotten so hardware heavy these days?
I get that some things require more ram, larger screen resolutions and games.
But even calculator apps are now in the hundreds of MB when the entire Microsoft office suite used to come on a couple of floppies.
Is it laziness and relying on ever higher level languages or is there some reason that stuff gets unnecessarily large now.14 -

Sometimes I have to work with physical hardware. There are over 300 machines in our lab, split among two subnets. But for some reason, I can never access my machines by hostnames.
Every other week, there's an IP conflict on this network, requiring me to log into the active directory server and delete old DNS entries. This usually happens because someone decided to deploy 64 VMs on a huge server, all at once, didn't boot them with a delay, let alone with with a warning to IT.
Then when my superior asks how my progress has been and I respond with "I can't even get the machines to ping each other by hostname, there's something wrong with the DNS:, I get the following response: "HOW COME NOBODY ELSE IS HAVING PROBLEMS WITH THIS. YOU'RE FULL OF SHIT", from someone who spends 90% of the year abroad, working remotely.5 -

So I'm working our remote build/testing server, and all of a sudden my computer just turns off. No crash message, no error, just turned off. My co-worker tries to help troubleshoot the problem.
Nothing.
I take the computer downstairs to the hardware department. They plug it in and it starts no problems.
After it finishes updating, I take it back upstairs and plug it back in.
Nothing.
I suggest that it is the power cable, and my co-worker looks under his desk. Turns out he had kicked the switch on the surge protector. 😑1 -
Hey hardware hackers, just wanted to let you know that seeedstudio offers free PCB assembly. I got 5 pieces of the PCB in the picture for 30 USD manufactured, assembled and shipped (including BOM costs), the also included 5 additional empty PCBs. However I paid another 30$ for customs and DHL customs handling (I'm inside Europe) ... But still, for assembly it's a great price, took around 4 weeks. Just upload the BOM and you get an instant quote. If you are curious, it's a simple board for an ESP32 with some mosfet drivers and two DC-DC converters.

Why people think that Mac is better than pc? Im Mac user and I like Mac. I think Apple just uses better hardware and charges extra for it. If you build windows with better hardware then windows will work really fast too. On Mac gradle build takes really less time because of SSD it does not mean Mac is faster. Get SSD for windows and see the difference yourself.

Coding chalenge.
So... Spent almost two hours to put this little device to work with the keypad.
The device is a arduino micro, special one that can work as mouse /keyboard or any kind of input on most devices (pc, Android phone,...)
The objective is to make a macro keypad to:
- Fast insert text
- Play sounds in games over voice chat.
Think of it like this, you start a new html file, press one key and all the base code is inserted.
So... Why so long? Tought was the hardware, tought the keypad could be set differently that most, code mistakes...
My error was all here, masked from the debugger by a if:
char keys[ROWS][COLS] = {
{'1','2','3','4'},
{'5','6','7','8'},
{'9','10','11','12'},
{'13','14','15','16'}
};
Easy to figure right? Only saw it after reading all the code twice.

Briefly blending amoung holiday tech consumers at Micro Center waiting for key-holder assistance @SSDs.
Rando: "they finally have a sale on *X, rebranded, price++* for my *ref'd only by part names* setup! What are you getting?"
Me: "replacement SSD, laptop's finally failing"
Rando: "Yeah, I totally get you, I hate that. How old is it? Hopefully you got a couple years outta it?"
Me: "over 7yrs old."
Rando: "Wow! Mustve not used it too much, still that's pretty long."
Me: "Actually, it's been my primary device, heavily used, as I'm a dev. I just know what/when to use SSD vs the HDD."
Rando: "Duuude, that's awesome!...wait...why haven't you just bought a new laptop yet?"
Me: "I'm not for hardware abuse or burning money"

When I was younger I had a decision to go into hardware or software. I chose software and have loved it.
Recentily I just spent 5 hours trying install a Linux distro on an old server. I made no progress.
I made the right decision. Hardware freaking sucks! You spend hours working on outdated pieces of crap and find that to fix your problem you need to sell you kidney to finance your project. Not to mention you have to wait for literally everything! It's like gradel builds everywhere! Want to install a new distro on your USB? Bam, 5min gone. Want to boot into bios and change one setting? BAM! more time wasted...

I am trying to reverse engineer a fingernail hardening device for rapid hardware prototyping (becoming some kind of hardware developer I guess)

It would help a lot but no. And messing around with high voltage is no fun.
I'm unsure if this fits as a dev rant since most/all I've read so far are software-related.

One of our servers had a disk fail this week. Luckily it's 1 of 3 in a RAID5 array. And, luckily, it was our mostly-dev box and didn't have any production stuff on it, except for some support things. We scheduled a disk replacement with the hosting company, took everything down, waited. Somebody at the hosting company apparently didn't know we'd scheduled the replacement, saw the machine was down, and brought it up again. Sigh. Finally they did the replacement, got it back up, but now we're seeing an ethernet port flapping, suggested they have someone go in and make sure all the jacks are fully seated, maybe one got loose when they were doing the disk switch. Bureacracy reared up again and we got the boilerplate "if there's a hardware issue suspected please boot into rescue mode and run the tests"... sigh...8

None - It's a Hardware Problem -
So, was testing a classic Mac an old friend sent over and realized an interesting convergence had occurred in my office.
In the attached shot you can see the following:
Center: A Macintosh LC III - effectively the last of the 68k Mac line
Right: A PowerMac G5 - one of the old cheese graters, and the last major release of the PowerPC line
Left, under the monitor: A 2020 Mac Mini - effectively the end of the Intel Mac line
The LC III gives a startup chime, but I wasn't able to get a video signal out of it using the Apple-to-VGA adapter I was using. Otherwise I'd be posting a shot with all 3 up and running.

Hardware Developing.
My current school project where I build a gps thief lock for my moped had me realized one thing. I don't want to go into Hardware Developing. The first problem took me about 4 months until I finally gave up and solved it differently. And this goes on and on and on. You fixed something and the next day it doesn't work anymore for some reason. I never had this problem when coding. It's fun to do stuff with electronics but coding is just way more rewarding.

And I was wondering why the fuck nothing happened... because that method got executed every second or so and should've moved the motor.

The evolving of software engineering is highly dependent on hardware engineering.
If only software engineering would evolve then there would eventually be a point where theres nothing more to do due to the lack of hardware to develop software for.
So its more a question of how you see hardware engineering evolving.
I expect that there will be a point in the future where we have techology which in big scale does dangerous or time consuming tasks. Like for example at nuclear reactors or at other high level security and high risk locations. This of course requires highly sofisticated ai software. -
Acer vs MSI Laptops.
Five years ago I bought an acer aspire vn7-591 laptop in Redcoon. It was the expensive laptop I bought ever in those days. My experience at the beginning was really bad because the battery laptop crashed after few months and the screen had some vague/dead pixels, but the worst was the imminent bankruptcy of Redcoon. So I couldn't use the warranty. Anyway, It didn't bother so much I have been enjoying this laptop and still doing it. However, last year the screen put me on alert since it started to fail with vertical bars and color changes.
It was time to buy a new computer and due to the problems with some of the components, I've decided to buy a laptop from a company with a better reputation than Acer in aspects as the reliability of the components.
My choice was a Msi Prestige 15 because of the thunderbolts, since the rest of specs are 'more or less similar', although it has more updated hardware, it is lighter, battery holds up to 4-5 hours etc... But... It is really noisy compared to my Acer computer. 2 CPU fans are around 3000 rpm in idle state... Acer seems to be working without using the fans if you are doing intensive work. I google it as I thought it was a factory problem, but it seems to be not a malfunctioning... In fact I found other users complaining about the same and the community proposed to reduce the fan speed through software.
Right now I have both laptops working and since the new boy is in house, Acer is working flawlessly. I am preparing the Acer for my girlfriend as a gift, otherwise it is a pitty to shut it down and store it in a wardrobe.
So, this is my impression about ACER and MSI. I m still experiencing with the new laptop, but I find weird things like the fan speed or how hot it gets in idle despite it uses a new generation of intel i7 cpu with lower consumption... I should monitor the power consumption...8 -
Modern hardware is rubbish. I recently donated a load of computers from the 1970s and 1980s to a technology museum, they all worked well and could still be used and set up in the museum's displays. My more recent stuff, from the last few years, I decided to sell on eBay. Some of it just had to be thrown out, mostly due to non-replaceable batteries that would no longer charge. What nonsense is this? Why is it easier to use a 35-year-old computer than a 3-year-old Chromebook or 5-year-old iPad?5

What's with so many developers using shitty hardware? It's literary the one tool you need for your profession, there should be absolutely no objection to having the best one available. Stop bitching about some software using 50% of your CPU when you're on the bare entry-level HW ffs! And don't give me that "can't afford it" bullshit. If you take your car to the repair shop, you're also paying for the tools needed for the job; the same way, your customers need to pay for the tools you need as a developer. If you can't afford that, there's clearly not enough demand for the work you do, so go find a different job.11

Hardware dying again as of last night. Tried each RAM stick individually and my two original ones seem to be the cause so far. If it dies again with the extra sticks I had in, them I'm going to assume motherboard is packing up. Already tried a spare PSU and ruled that out.
Memtest died midway at random points several times and once it tried to boot around 10 times and died at various points along the way.
I just wish there was a more reliable way to test motherboards and power supplies on the PC itself. Also, I'll be stuck with only 4GB RAM from me new sticks 😭 -

I am looking at replacing my Dell XPS 15 from 2019, but because I work 100% remote I am considering building a desktop developer rig instead of getting a new laptop. I have only had laptops since early 2000s, but thought it would be fun building something from scratch again. The problem is I have fallen tragically behind on everything hardware, and therefore looking for some pointers.
I don't want an RGB rainbow unit with 6 loud fans requiring a noise cancelling headset to work on. I want a top spec, stealthy thing that has all the goodies but also runs quiet. A decent graphics card that can run the latest games at a decent frame rate, but not the top of the line either.
Any tips on cases, motherboards, RAM, drives, fans and grahpics cards appreciated. The budget is roomy, comparable to a top spec Dell XPS 15 or ThinkPad X1 Extreme.12 -

Hardware classes for software dev student?
Hey guys. Currently getting into second year of a 5 year curriculum to get an 'Integrated Master of Computer Engineering & Informatics' Degree here in Greece.
I'm already into software, I'm fooling around with java, go and php, making some games, web services and anything I find interesting in general. Recently, with the logic design class, I started liking hardware stuff (I didn't really like them before).
We're getting to a point where we might have to decide between picking hardware-centered or software centered subjects. I'm thinking that I can probably learn whatever is taught on the software side by myself (with a bit more studying of course), whereas hardware would be more difficult to study alone.
That said, I'm considering picking hardware, but I am skeptical. What do you think? I'll certainly miss out on the concurrent processing, data structure and how-a-compiler-works classes.
What do you think?

Microsoft announced a new security feature for the Windows operating system.
According to a report of ZDNet: Named "Hardware-Enforced Stack Protection", which allows applications to use the local CPU hardware to protect their code while running inside the CPU's memory. As the name says, it's primary role is to protect the memory-stack (where an app's code is stored during execution).
"Hardware-Enforced Stack Protection" works by enforcing strict management of the memory stack through the use of a combination between modern CPU hardware and Shadow Stacks (refers to a copies of a program's intended execution).
The new "Hardware-Enforced Stack Protection" feature plans to use the hardware-based security features in modern CPUs to keep a copy of the app's shadow stack (intended code execution flow) in a hardware-secured environment.
Microsoft says that this will prevent malware from hijacking an app's code by exploiting common memory bugs such as stack buffer overflows, dangling pointers, or uninitialized variables which could allow attackers to hijack an app's normal code execution flow. Any modifications that don't match the shadow stacks are ignored, effectively shutting down any exploit attempts.5 -

Here is where it gets tricky: obvioisly it would be easy to build a dedicated system for this purpose but I want to use an existing system with an existing psu. I still want to use the pc normally at home with the standard psu but don't fell like switching every single power connector everytime I take the pc into or out of the van. Do you have any idea how to make some sort of switching mechanism so that I can leave the Hardware as it is and just power it of any of the two psus?

Bonus will come in soon and its time for a new laptop. Had my xps13 since ~2016 and I absolutely loved it - the keyboard is amaaazing.. But the display is broken and as its a touch, its ridiculously expensive to replace so that's not an option..
Want to keep it around 1k$ and mostly care about the keyboard being nice, robust case (not plastic), size (no bigger than 13") and storage (at least 1TB SSD).
Ideally it would have an integrated SD slot and at least 1 USB-A...
Any suggestions? I'm gonna put Linux on it anyway so performance just has to be medium.
Thinking about getting another xps but they got a good bit more expensive and I know there's other devices our there nowadays that check the boxes, like thinkpad for example.
