Well that was a fun call I just had.

Owner of the company I freelance for: Hey I forgot to tell you something.

Me: What?

Owner: I bought you a plane ticket to fly to Puerto Rico. You're heading out in a month.

Me: What?! Why????

Owner: To set up cryptocurency mining rigs.

Me: Just because I know a bit about mining doesn't make me an expert.

Owner: We have $80k in our pocket in investments from outside parties, with another $20-30k on the way. You get 20% of the coins mined for as long as you manage it.

Me: So we're gonna set up several rigs, utilizing a b250 motherboard, g4400 CPU, 8GB of RAM and 10 GPUs each. We'll have AMD rigs for monero and Nvidia rigs for Ethereum and others. We'll use awesome miner for profitability switching on the fly. Each machine is probably going to be $5k each, possibly $4k with bulk discounts. We'll need at least 1500W per rig for power, 2000W to be safe, so we need to make sure we have ample power delivery to the mining warehouse.

Owner: I thought you weren't an expert?

Me: I'm not, but when there's money involved my motivation to Google goes into overdrive.

Is java reaching multiple dimension to pull extra cpu power?

My wife = Best wife

Her: Is that the motherboard and CPU you wanted?

Me: Yes, you get alot of power for the money (Ryzen 7 1800)

Her: Alright, you should order thoose things next week if they are not on sale this friday

Dad calls:
D: Hai, so, um, my pc's not booting up.
Me: So?
D: What do I do now?
M: You tried fixin' it?
D: That's why I'm calling you.
M: I'm 400km away from you. Does it do anything by pressing a power-on button?
D: No. But I touched it, it's really hot.
M: When was the last time you cleaned that shit up?
D: I have to clean it?
*PC is located at dusty environment at work. 5 years old and is being turned on 6 days a week*

Clean. Your. Pc.
Oh, and yeah, it overheated, burned the mbo, power suply, and cpu cooler stopped spinning.
It's like Satan threw a curse on a pc, and took a piss on it.
The best part? He's mad because I "never help him nor have time when he needs something to be fixed".
He can fix the PC in a pc shop that is across the street.

So, you doin' any better this week?

At age of 20, I got hired as junior dev at a mobile gaming company. We were 2 junior devs hired at the same time and one of our senior colleagues made a prank: he came in the office before us and rearranged our offices in a "funny" manner.

Two days later I waited for him to go home. I opened his PC case, removed the power button cable from the motherboard and then re-arranged everything back to normal. Well, I couldn't resist...

Next day he came into the office and, well, surprise... the PC was not starting. He went to the IT department and they spent 4 hours trying to figure out why it was not working. They replaced the CPU, RAM memory, including the PSU.

I had to go and tell them: "maybe it's the power button jack?!".

I got into some problems for that prank. Indeed I crossed a line, but what the hell... that was a bad IT department.

one of our computers at work suddenly shut down. our boss panicked like it was the end of the world cause he knew we couldnt buy a new one and we desperately need the computer. when i came in he started telling me he's gonna pay me extra if i fix the computer

me: *checks cpu and finds out it was unplugged* u sure bout that?
him: hell yea, id rather pay u that buy a new one

*30 mins later*

me: *plugs it back in and pushes power button* its done

>> guess who's got extra money without any extra efforts yay

I'm getting ridiculously pissed off at Intel's Management Engine (etc.), yet again. I'm learning new terrifying things it does, and about more exploits. Anything this nefarious and overreaching and untouchable is evil by its very nature.

(tl;dr at the bottom.)

I also learned that -- as I suspected -- AMD has their own version of the bloody thing. Apparently theirs is a bit less scary than Intel's since you can ostensibly disable it, but i don't believe that because spy agencies exist and people are power-hungry and corrupt as hell when they get it.

For those who don't know what the IME is, it's hardware godmode. It's a black box running obfuscated code on a coprocessor that's built into Intel cpus (all Intell cpus from 2008 on). It runs code continuously, even when the system is in S3 mode or powered off. As long as the psu is supplying current, it's running. It has its own mac and IP address, transmits out-of-band (so the OS can't see its traffic), some chips can even communicate via 3g, and it can accept remote commands, too. It has complete and unfettered access to everything, completely invisible to the OS. It can turn your computer on or off, use all hardware, access and change all data in ram and storage, etc. And all of this is completely transparent: when the IME interrupts, the cpu stores its state, pauses, runs the SMM (system management mode) code, restores the state, and resumes normal operation. Its memory always returns 0xff when read by the os, and all writes fail. So everything about it is completely hidden from the OS, though the OS can trigger the IME/SMM to run various functions through interrupts, too. But this system is also required for the CPU to even function, so killing it bricks your CPU. Which, ofc, you can do via exploits. Or install ring-2 keyloggers. or do fucking anything else you want to.

tl;dr IME is a hardware godmode, and if someone compromises this (and there have been many exploits), their code runs at ring-2 permissions (above kernel (0), above hypervisor (-1)). They can do anything and everything on/to your system, completely invisibly, and can even install persistent malware that lives inside your bloody cpu. And guess who has keys for this? Go on, guess. you're probably right. Are they completely trustworthy? No? You're probably right again.

There is absolutely no reason for this sort of thing to exist, and its existence can only makes things worse. It enables spying of literally all kinds, it enables cpu-resident malware, bricking your physical cpu, reading/modifying anything anywhere, taking control of your hardware, etc. Literal godmode. and some of it cannot be patched, meaning more than a few exploits require replacing your cpu to protect against.

And why does this exist?
Ostensibly to allow sysadmins to remote-manage fleets of computers, which it does. But it allows fucking everything else, too. and keys to it exist. and people are absolutely not trustworthy. especially those in power -- who are most likely to have access to said keys.

The only reason this exists is because fucking power-hungry doucherockets exist.

Sell a 2000€ laptop with all the ram cpu power 4k display you name it.
Throw in a 5400rpm mechanical hdd as standard.

Sooo, in my 5 years of high school, I had 5 different IT teachers...
Now, in Italy Highschool goes from 14 to 19 years old, I started programming some days after becoming 13, and "programming" classes begin on the third year, so I had quite a headstart on my classmates...

Now, for the third year, I had an awesome teacher, he noticed I was ahead and... Bored, so he gave me some extra stuff to study, he's the only teacher I've learnt anything from, it was awesome, very stingy with grades, but getting a perfect score with him was so satisfying.

Fourth year, the new guy was old, very old, at least 70, his lessons were just him talking about how programming was when he was young.

But then... During the second half of the fourth year I changed class due to bullying under a teacher's advice, and HE happened...

My new IT teacher, one of the most ignorant, awful people I ever met...
He's literally the reason I only went back to that school once, because another teacher needed help with a course...
One day I made the HUGE mistake to say that his "while(i <10000000000000);" wasn't very efficient for making a delay, because it didn't free the CPU, and since then:
- I never got more than 7 out of 10 at his tests
- He insulted me in front of the whole class
- He sabotaged the oral part of my final exam, shouting that he hated D'Annunzio when he saw he was in the literature part of my thesis (needed him to connect to WW2, and the Memex, that then allowed me to start talking about PCs and programming, my thesis was about the influence of lisp on modern programming languages), loudly chatting with other teachers when I was trying to keep calm (a teacher who knows me quite well, and was there to see my "performance" thought I was going to snap at some point), distracting the english teacher when I was exposing the english part of my thesis and pressuring the commission to give me 99 instead of 100 out of 100

So yeah, he almost made me hate the only thing I'm good at, undervaluing my work and my skills, undervaluing and humiliating me as a person, and I think that if I meet him again I might spit on his face...

So yeah, my biggest "programmer enemy" was a person that then did everything in his power to make my last year and a half of highschool hell

Now I can gladly say that with the help of my tutoring, some of my university colleagues are starting to appreciate programming, and my engineer friends ask for my help when they need advices about their code, and it's giving me motivation to keep doing it and becoming a better programmer to keep up with their expectations

3 rants for the price of 1, isn't that a great deal!

1. HP, you braindead fucking morons!!!

So recently I disassembled this HP laptop of mine to unfuck it at the hardware level. Some issues with the hinge that I had to solve. So I had to disassemble not only the bottom of the laptop but also the display panel itself. Turns out that HP - being the certified enganeers they are - made the following fuckups, with probably many more that I didn't even notice yet.

- They used fucking glue to ensure that the bottom of the display frame stays connected to the panel. Cheap solution to what should've been "MAKE A FUCKING DECENT FRAME?!" but a royal pain in the ass to disassemble. Luckily I was careful and didn't damage the panel, but the chance of that happening was most certainly nonzero.
- They connected the ribbon cables for the keyboard in such a way that you have to reach all the way into the spacing between the keyboard and the motherboard to connect the bloody things. And some extra spacing on the ribbon cables to enable servicing with some room for actually connecting the bloody things easily.. as Carlos Mantos would say it - M-m-M, nonoNO!!!
- Oh and let's not forget an old flaw that I noticed ages ago in this turd. The CPU goes straight to 70°C during boot-up but turning on the fan.. again, M-m-M, nonoNO!!! Let's just get the bloody thing to overheat, freeze completely and force the user to power cycle the machine, right? That's gonna be a great way to make them satisfied, RIGHT?! NO MOTHERFUCKERS, AND I WILL DISCONNECT THE DATA LINES OF THIS FUCKING THING TO MAKE IT SPIN ALL THE TIME, AS IT SHOULD!!! Certified fucking braindead abominations of engineers!!!

Oh and not only that, this laptop is outperformed by a Raspberry Pi 3B in performance, thermals, price and product quality.. A FUCKING SINGLE BOARD COMPUTER!!! Isn't that a great joke. Someone here mentioned earlier that HP and Acer seem to have been competing for a long time to make the shittiest products possible, and boy they fucking do. If there's anything that makes both of those shitcompanies remarkable, that'd be it.

2. If I want to conduct a pentest, I don't want to have to relearn the bloody tool!

Recently I did a Burp Suite test to see how the devRant web app logs in, but due to my Burp Suite being the community edition, I couldn't save it. Fucking amazing, thanks PortSwigger! And I couldn't recreate the results anymore due to what I think is a change in the web app. But I'll get back to that later.

So I fired up bettercap (which works at lower network layers and can conduct ARP poisoning and DNS cache poisoning) with the intent to ARP poison my phone and get the results straight from the devRant Android app. I haven't used this tool since around 2017 due to the fact that I kinda lost interest in offensive security. When I fired it up again a few days ago in my PTbox (which is a VM somewhere else on the network) and today again in my newly recovered HP laptop, I noticed that both hosts now have an updated version of bettercap, in which the options completely changed. It's now got different command-line switches and some interactive mode. Needless to say, I have no idea how to use this bloody thing anymore and don't feel like learning it all over again for a single test. Maybe this is why users often dislike changes to the UI, and why some sysadmins refrain from updating their servers? When you have users of any kind, you should at all times honor their installations, give them time to change their individual configurations - tell them that they should! - in other words give them a grace time, and allow for backwards compatibility for as long as feasible.

3. devRant web app!!

As mentioned earlier I tried to scrape the web app's login flow with Burp Suite but every time that I try to log in with its proxy enabled, it doesn't open the login form but instead just makes a GET request to /feed/top/month?login=1 without ever allowing me to actually log in. This happens in both Chromium and Firefox, in Windows and Arch Linux. Clearly this is a change to the web app, and a very undesirable one. Especially considering that the login flow for the API isn't documented anywhere as far as I know.

So, can this update to the web app be rolled back, merged back to an older version of that login flow or can I at least know how I'm supposed to log in to this API in order to be able to start developing my own client?

- If I buy x amount of ram | hard drive space | cpu power I will never need more.
- No need for version control | Tests. This is a small project
- git commit -m "changes" (its a small change. I will remember why I did it)
- It is too obvious that I put a lot of personal time in this so my boss will definitely notice!
- Why comment this simple method? Anyone should know what it does. Especially me!
- "this should never happen"
- This call can't be from work. Everyone knows I am on vacation.
- I will back up next week. It's not like it is going to crush today.
- It’s 11:30 already? I will work on this for only a half hour more and then I will definitely go to bed!
- This project will take x amount of time!

I fucking hate it when I see videos or read articles saying "you don't need a powerful laptop for development"

Do you even code?
From mobile to web Dev. Every tool now demands a lot ram and cpu power to run.

You at least have an ide and chrome open. These with the OS can reach the 8gb ram limit.

Also the screen, you need atleast a 1080p! I had a 15in 768p laptop for 5 years. I hated development on that.

Fucking hate people who think we can develop on a potato.

Doing linguistic research where I need to parse 2000 files of a total of 36 GB. Since we are using python the first thing I thought was to implement multi threading. Now I changed the total runtime from three days to like one day and a half. But then when I checked the activity monitor I saw only 20 percent of the CPU usage. After a searching process I started to understand how multi threading and multi processing works. Moral of the story: if you want to ping a website till they block you or do easy tasks that will not use up all power of one core, do multi thrading. If you need to do something complicated that can easily consume all the powers of a single CPU core, split up the work and do multi processing. In my case, when I tried to grab information from a website, I did multi thrading since the work is easy and I really wanted to pin the website 16 times simultaneously but only have 4 cores. But when it come to text processing which a single file will take 80 percent of cpu, split it up and do multi processing.

This is just a post for those who are confused with when to use which.

I wish people that made desktop apps would consider cpu and ram usage. "Oh I've just opened... ...let me index your vendor folder and check that I need to update at the same time whilst you only have 20% cpu left and 2GB of RAM remanding :D" no; fuck off. Why don't you wait until there's enough CPU power left to check for your update?

So I saw an article where in the author mentioned that "how will we earn money when there are so many adblock users, indirectly blocking out income, so we had to take some measures and that how we initiated coinhive on our websites, where in, it uses minimal cpu power for coin mining of every user that visits that webpage"

WTF, saying minimal, some users commented their saying they experienced sudden over usage of cpu cores and rise in temps while visiting the websites.

How do you justify such behavior, I feel kinda biased as I feel bad for them, but on the other hand, they just shouldn't rely on writing articles as a job/source of income

I do not like the direction laptop vendors are taking.

New laptops tend to feature fewer ports, making the user more dependent on adapters. Similarly to smartphones, this is a detrimental trend initiated by Apple and replicated by the rest of the pack.

As of 2022, many mid-range laptops feature just one USB-A port and one USB-C port, resembling Apple's toxic minimalism. In 2010, mid-class laptops commonly had three or four USB ports. I have even seen an MSi gaming laptop with six USB ports. Now, much of the edges is wasted "clean" space.

Sure, there are USB hubs, but those only work well with low-power devices. When attaching two external hard drives to transfer data between them, they might not be able to spin up due to insufficient power from the USB port or undervoltage caused by the impedance (resistance) of the USB cable between the laptop's USB port and hub. There are USB hubs which can be externally powered, but that means yet another wall adapter one has to carry.

Non-replaceable [shortest-lived component] mean difficult repairs and no more reserve batteries, as well as no extra-sized battery packs. When the battery expires, one might have to waste four hours on a repair shop for a replacement that would have taken a minute on a 2010 laptop.

The SD card slot is being replaced with inferior MicroSD or removed entirely. This is especially bad for photographers and videographers who would frequently plug memory cards into their laptop. SD cards are far more comfortable than MicroSD cards, and no, bulky external adapters that reserve the device's only USB port and protrude can not replace an integrated SD card slot.

Most mid-range laptops in the early 2010s also had a LAN port for immediate interference-free connection. That is now reserved for gaming-class / desknote laptops.

Obviously, components like RAM and storage are far more difficult to upgrade in more modern laptops, or not possible at all if soldered in.

Touch pads increasingly have the buttons underneath the touch surface rather than separate, meaning one has to be careful not to move the mouse while clicking. Otherwise, it could cause an unwanted drag-and-drop gesture. Some touch pads are smart enough to detect when a user intends to click, and lock the movement, but not all. A right-click drag-and-drop gesture might not be possible due to the finger on the button being registered as touch. Clicking with short tapping could be unreliable and sluggish. While one should have external peripherals anyway, one might not always have brought them with. The fallback input device is now even less comfortable.

Some laptop vendors include a sponge sheet that they want users to put between the keyboard and the screen before folding it, "to avoid damaging the screen", even though making it two millimetres thicker could do the same without relying on a sponge sheet. So they want me to carry that bulky thing everywhere around? How about no?

That's the irony. They wanted to make laptops lighter and slimmer, but that made them adapter- and sponge sheet-dependent, defeating the portability purpose.

Sure, the CPU performance has improved. Vendors proudly show off in their advertisements which generation of Intel Core they have this time. As if that is something users especially care about. Hoo-ray, generation 14 is now yet another 5% faster than the previous generation! But what is the benefit of that if I have to rely on annoying adapters to get the same work done that I could formerly do without those adapters?

Microsoft has also copied Apple in demanding internet connection before Windows 11 will set up. The setup screen says "You will need an Internet connection…" - no, technically I would not. What does technically stand in the way of Windows 11 setting up offline? After all, previous Windows versions like Windows 95 could do so 25 years earlier. But also far more recent versions. Thankfully, Linux distributions do not do that.

If "new" and "modern" mean more locked-in and less practical and difficult to repair, I would rather have "old" than "new".

I had spent the last year working on a online store power by woocommerce with over 100k products from various suppliers. This online store utilized a custom API that would take the various formats that suppliers offer their inventory in and made them consistent. Now everything was going swimmingly initially, but then I began adding more and more products using a plug-in called WP all import. I reached around 100k products and the site would take up to an entire minute to load sometimes timing out. I got desperate so I installed several caching plugins, but to no avail this did not help me. The site was originally only supposed to take three to four months but ended up taking an entire year. Then, just yesterday I found out what went wrong and why this woocommerce website with all of these optimizations was still taking anywhere from 60 to 90 seconds to load, or just timing out entirely. I had initially thought that I needed a beefier server so I moved it to a high CPU digitalocean VM. While this did help a little bit, the site was still very slow and now I had very high CPU usage RAM usage and high disk IO. I was seriously stumped the Apache process was using a high amount of CPU and IO along with MYSQL as well. It wasn't until I started digging deeper into the database that I actually found out what the issue was. As I was loading the site I would run 'show process list' in the SQL terminal, I began to notice a very significant load time for one of the tables, so I went to go and check it out. What I did was I ran a select all query on that particular table just to see how full it was and SQL returned a error saying that I had exceeded the maximum packet size. So I was like okay what the fuck...
So I exited my SQL and re-entered it this time with a higher packet size. I ran a query that would count how many rows were in this particular table and the number came out to being in the millions. I was surprised, and what's worse is that this table belong to a plugin that I had attempted to use early in the development process to cache the site. The plugin was deactivated but apparently it had left PHP files within the wp content directory outside of the actual plugin directory, so it's still executing scripts even though the plugin itself was disabled. Basically every time I would change anything on the site, it would recache the whole thing, and it didn't delete any old records. So 100k+ products caching on saves with no garbage collection... You do the math, it's gonna be a heavy ass database. Not only that but it was serialized data, so when it did pull this metric shit ton of spaghetti from the database, PHP then had to deserialize it. Hence the high ass CPU load. I had caching enabled on the MySQL end of things so that ate the ram. I was really desperate to get this thing running.
Honest to God the main reason why this website took so long was because the load times made it miserable to work on. I just thought that the hardware that I had the site on was inadequate. I had initially started the development on a small Linux VM which apparently wasn't enough, which is why I moved it to digitalocean which also seemed to not be enough, so from there I moved to a dedicated server which still didn't seem to be enough. I was probably a few more 60-second wait times or timeouts from recommending a server cluster to my client who I know would not be willing to purchase it. The client who I promised this site to have completed in 3 months and has waited a year. Seriously, I would tell people the struggles that I would go through with this particular site and they would just tell me to just drop the site; just take the money, just take the loss. I refused to, this was really the only thing that was kicking my ass. I present myself as this high-and-mighty developer like I'm just really good at what I do but then I have this WordPress site that's just beating the shit out of me for a year. It was a very big learning experience and it was also very humbling as well, it made me realize that I really don't know as much as I think I might. It was evidence that there is still so much more to learn out there, I did learn a lot from that experience especially about optimizing websites the different types of methods to do that particular lonely on the server side and I'll be able to utilize this knowledge in the future.
I guess the moral of the story is, never really give up. Ultimately things might get so bad that you're running on hopes and dreams. Those experiences are generally the most humbling. Now I can finally present the site that I am basically a year late on to the client who will be so happy that I did not give up on the project entirely. I'll have experienced this feeling of pure euphoria, and help the small business significantly grow their revenue. Helping others is very fulfilling for me, even at my own expense.

Anyways, gonna stop ranting. Running out of characters. If you're still here... Ty for reading :')

Continued from previous post.

The man with hoodie walked down a dark alley. At distance, a house which looked haunted stood. As he entered the house he sighed a relief. Once inside, he descends to the basement where an old computer sat. He turned on the computer and smiled. The screen showed a prompt. With fews keystrokes, a series of scripts begin to execute. Finally at the bottom, a text blinked.
"Awaiting Connection........"

The CPU was recovered from rubble and brought to General's office as per his order. It was connected to a power source and it started to boot. A prompt showed up. A man in suit, suggested perhaps it expected a login. The General sat on his chair smoking a cigar thinking on what action must be taken next.

While men in suit discussed about the CPU, someone plugged in a LAN cable. The General who was lost in thought, saw this from corner of his. A moment passed. General sprang from his chair, hurling his cigar to the floor. As men in suits, looked at the General's display of athletic behavior they sensed the tension. Everyone turned to the CPU now connected to LAN now.

Far way, the screen on hooded man computer showed. "Connected".
A series of scripts started to execute.
Cold wind was all that could be heard out side the General's office building and the house, where hooded man sat in the dark.

Incredibly drunk last night.

Decided to take the CD/DVD drive out of my old PC (now a server) and put it into my new gaming PC.

Required a partial rebuild because:
1) GPU was too close to PSU to plug in a new SATA power line
2) CPU cooling lines were directly in the way of the space for the DVD/CD bay
3) Had to route the new power cables of course

Incredibly, even though I couldn't stand, I was able to perfectly execute the maintenance on both machines and I'm even using the new PC to write this rant now.

I must be a God.

Got my new PC up and running!

CPU: AMD Ryzen 5 3400G (APU)
Cooler: Scythe Mugen 5
Mobo: Asus B450-F Gaming ROG Strix
RAM: Crucial Ballistix 2x16GB
SSD: Samsung 2TB M2 Evo 860

PSU: Bequiet Straight Power 11 550W
Case: Lancool PC-K58 (10 years old)
Case fans: Bequiet Silentwings 3 140mm (front), Silentwings 2 120mm (back)

The cooler is massively oversized for the CPU, but perfect for a silent PC.

OS: Linux Mint 20 Cinnamon

As much as I loved Win 7, but it's over, and Win 10 just isn't acceptable.

This is why I hate Windows:

For about a month now, I've been learning/working on salesforce, so my Macbook was enough for me.
Today there was a bug in something I built in iur Python backend, and since it has a dependency on windows, I booted the old guy up.

And this is what I see. For about 1.5 hours this went on.

Then it started, but system consuming 100% disk and 80+% CPU. Can't do a thing.

And when zoom finally opened (for a quick meet), the camera turned on halfway down the meeting, and then the system restarted on it's own.

Old man showing that same screen again for more than 30 minutes.

Since I have dual boot on this one, I hard-shutdown it using power button, and now boot into ubuntu 20. This works so beautifully (although it froze for about 5 seconds before popping up the updates panel, something I CHOSE to keep enabled). I try going back to Windows, and it's hell again.

Here I am now trying to set up a ec2 instance and setup the app source there so that I can debug with RDP.

And yeah, Component Object Model is a motherfucking bitch. Person who invented it should die. People who build apps leveraging this should die. Business leaders who say "Hey this app (built with COM) can solve the problem easily, so use this" should die choking on their own phallus. And developers like me who keep using this because "the last guy did this" should die too.

Microsoft and it's products are the death of sane people.

Fucking Gates. Its the same damn hardware.

I haven't built a new computer in 9 years, but I finally, finally got together enough money to go big.

POWER: Seasonic Focus Plus 850W 80+ Gold

I can't fucking wait for it to arrive.

Any idea how to make a fan in an HP laptop spin at lower temperatures? The fan in my Pavilion dm-1 only starts spinning when CPU reaches 75°C and enters full speed when the GPU also becomes 75°C. Which is strange because this CPU and GPU are one and the same thing.. an APU. And overheating freezes often happen at around 75-80°C.. which isn't too much of a headroom really. I'd rather have it kick in at 50-60°C already, but would like to avoid using the power of the soldering iron for it.. I've already lost a fan to that previously (current one is a spare part from AliExpress). Granted, my soldering experience was much less back then.. nowadays I can probably even solder 1206 SMD packages comfortably. But I don't want to risk it, and I've got experience with custom kernels anyway.. are there any fan speed governors in the kernel that you know of?

FWIW, fancontrol doesn't seem to be supported on this laptop, and neither is pwmconfig. Perhaps I'll have to stick to the electronics method after all? Given that it's just a 5V fan, I guess that I could feed it power by tapping some power from a USB rail and controlling its speed from an ATtiny85.. but inside the laptop there isn't enough space for that and I don't feel like freeing this hardware out of its laptop chassis yet (though that is on the list). Either way running at 60°C under no load is terrible.. some HP certified enganeering "feature" I guess...

what fucking system has a coprocessor after 2002? (My laptop is a 2008 HP something or other)

Hey Hey!

Have a look at my latest Ubuntu theme.

Displaying CPU-Power Manager where i can overlock, take control of my processor.

Drop down Terminal with a transparacy Gnome theme.

Quite far to go for someone with limited knowledge at the moment.

Any advice and feedback is welcome! :)

EDIT: !rant, forgot tags, sorry :(

Tfw your new laptop CPU gets the same performance as your 10y.o. desktop and is 10x more power efficient.

Ryzen 5 2500U (2018):
> 4c/8t
> 2GHz base / 3.6 turbo
> 15W TDP

Xeon W3520 (2009):
> 4c/8t
> 2.7GHz base / 2.9 turbo
>130W TDP

Running new hardware feels great.

WHY THE FUCK DOES THIS ALWAYS HAPPEN TO ME!
My system wont FUCKING POST! IT HAS POWER! IT HAS A CPU! IT HAS A GRAPHICS CARD! AND ALMOST ANY FAN IS FUCKING SPINNING! BUT NO FUCKING POST LED! FUCK THIS!

This is a guide for technology noobies who wants to buy a laptop but have no idea what the SPECS are meaning.

1. Brand
If you like Apple, and love their !sleek design, go to the nearest Apple store and tell them "I want to buy one. Recommendations?"
If you don't like Apple, well, buy anything that fits you. Read more below.

2. Size
There are 11~15 inches, weight is 850g ~ 2+kg. Very many options. Buy whatever you like.

//Fun part coming

3. CPU
This is the power of the brain.
For example,
Pentium is Elementary Schoolers
i3 is Middle Schoolers
i5 is High Schoolers
i7 is University People

Dual-core is 2 people
Quad-core is 4 people

Quiz! What is i5 Dual-core?
A) 2 High Schoolers.

Easy peasy, right?

Now if you have a smartphone and ONLY use Messaging, Phone, and Whatsapp (lol), you can buy Pentium laptops.
If not, I recommend at least i3

Also, there are numbers behind those CPU, like i3-6100
6 means 6th generaton.
If the numbers are bigger, it is the most recent generation.

Think of 6xxx as Stone age people
7xxx as Bronze age people
8xxx as Iron age people
and so one.

4. RAM
This is the size of the desk.
There are 4GB, 8GB, 16GB, 32GB, and so one.
Think of 4GB as small desk to only put one book on it.
8GB as a desk to put a laptop with a keyboard and a mouse.
16GB as a normal sized desk to put some books, laptop, and food.
32GB as a boss sized desk.
And so one.

When you do multitasking, and the desk is too small...
You don't feel comfortable right?
It is good when there are spacious space.
Same with RAM.

But when the desk becomes larger, it gets expensive, so buy the one with the affordable price.

If you watch some YouTube videos in Chrome and do some document words with Office, buy at least 8GB. 16GB is recommended.

5. HDD/SSD
You take out the stuffs such as books and laptop from the basket (HDD/SSD), and put in your desk (RAM).

There are two kinds of baskets.
The super big ones, but because it is so big, it is bulky and hard to get stuffs out of the basket. But it is cheap. (HDD)
There are a bit smaller ones but expensive compared to the HDD, it is called SSD. This basket is right next to you, and it is super easy to get stuffs out of this basket. The opening time is faster as well.

SSDs were expensive, but as times go, it gets bigger as well, and cheaper. So most laptops are SSD these days.
There are 128GB, 256GB, 512GB, and 1024GB(=1TB), and so one. You can buy what you want. Recommend 256GB for normal use.
Game guy? At least 512GB.

6. Graphics
It is the eyesight.
Most computers doesn't have dedicated graphics card, it comes with the CPU. Intel CPUs has CPU + graphics, but the graphics powered by Intel isn't that good.
But NVIDIA graphics cards are great. Recommended for gamers. But it is a bit more expensive.

So TL;DR

Buying a laptop is
- Pick the person and the person's clothes (brand and design)
- Pick the space for the person to stay (RAM, SSD/HDD)
- Pick how smart they are (CPU)
- Pick how many (Core)
- Pick the generation (6xxx, 7xxx ....)
- Pick their eyesight (graphics)

And that's pretty much it.
Super easy to buy a laptop right?

Guys, we need talk raw performance for a second.

Fair disclaimer - if you are for some reason intel worker, you may feel offended.

I have one fucking question.
What's the point of fucking ultra-low-power-extreme-potato CPUs like intel atoms?

Okay, okay. Power usage. Sure. So that's one.

Now tell me, why in the fucking world anyone would prefer to wait 5-10 times more for same action to happen while indeed consuming also 5-10 times less power?

Can't you just tune down "big" core and call it a day? It would be around.. a fuckton faster. I have my i7-7820HK cpu and if I dial it back to 1.2Ghz my WINDOWS with around lot of background tasks machine works fucking faster than atom-powered freaking LUBUNTU that has only firefox open.

tested i7-7820hk vs atom-x5-z8350.

opening new tab and navigating to google took on my i7 machine a under 1 second, and atom took almost 1.5 second. While having higher clock (turbo boost)

Guys, 7820hk dialled down to 1.2 ghz; 0.81v
Seriously.
I felt everything was lagging. but OS was much more responsive than atom machine...

What the fuck, Intel. It's pointless. I think I'm not only one who would gladly pay a little bit more for such difference.

i7 had clear disadvantages here, linux vs windows, clear background vs quite a few processes in background, and it had higher f***ng clock speed.

TL;DR
Intel atom processors use less power but waste a lot of time, while a little bit more power used on bigger cpu would complete task faster, thus atoms are just plain pointless garbage.

PS.
Tested in frustration at work, apparently they bought 3 craptops for presentations or some shit like that and they have mental problems becouse cheapest shit on market is more shitty than they anticipated ;-;
fucking seriously ;-;

its been there since many years, but:

When did we turned the wrong way and made it acceptable that Windows can blantly say in my face that i cannot deactivate the transmission of data unless i have the "Business" Variant of their Software. Its called Windows 10 PROFESSIONAL. Why are there no international Laws against that? Where was the molotov throwing mob when this became the norm?

Additonally. that cute telemetry service consumes a considerable amount of cpu and disk power from time to time.

and no, Linux is not an alternative. It never was. There is proprietary software and driver sets used for lab equipment and machines that cannot run under linux, noone will ever have the time to tool something for it and the user base is too specific to hope for any community solution.

sidenote: even Level 0 STILL transmits data. I want mode -1

What if people, life, humanity, the universe is just a cluster of CPUs running a giant Recurrent Neural Network algorithm? 🤔

-Sun and food == power source
-People == semiconductors
-Earth/a Galaxy == a single CPU
-Universe == a local grouping of nearby nodes, so far the ones we've discovered are dead or not what same data transport protocol/port as us
-Universal Expansion == the search algorithm
-Blackholes: sector failures
-Big Bang == God turns on his PC, starts the program
-Big Crunch == rm -rf

- a split keyboard with a touchpad in the middle that will let you control all gestures on a computer

- a set of desk/monitors that adjusts perfectly for ergo for anyone

- a vertical laptop dock that is modular so you can add extra memory/video processing power and only using your laptop as a CPU/secondary graphics card

- a set of kitchenware and plates that would be so easy to clean and would never get stained

-an insect home alarm system that tells you where the fucking insect is so it doesn't take you by surprise/you can call someone to remove it

- a clothing brand that has a buy one gift one operation mechanic, where you buy a shirt and an article is donated to a local charity

- a restaurant

- a simple, yet robust database option that walks users through creating good databases that is super user friendly

- an app that takes tattoo designs in any format, converts them, allows for editing, and then can hook up to a special printer that gives you the transfer you will use on the client

As a guy with a Intel 6800K I now really feel robbed of my money by Intel.

For over 10 years they knew of the heavy design flaw and put it through.

The ironic thing is, that every country will set up a penalty for Intel, but the Customers with the CPU's wont even see a buck.

It sucks that I have up to 30% less CPU Power after next weeks patch.
I will banish Intel now forever!! You should never come again in my Business!!!

Even my newly ordered Tablet with a Intel chip will suck d*ck now...

So for a while I have wanted to build a raspberry pi cluster. In the spirit of shia labeouf I got started last saturday.

I had two pies lying around so I figured I'd run some experiments before I invested in a lot of hardware. After about a day I had turned the two pies into a shared cluster when disaster struck....

I had completely ignored the fact that you cannot run 32 or 64bit software on an arm processor (I know... I'm a java developer). So when I booted my service and the load balancer, I found that nothing worked. So pretty bumbed out, I quit the project.

Later that day I found a crazy guy who had bought a batch of 400 small form factor PSUs (300W) and internally I laughed at him a little. I mean, who's gonna sell 300W irregular power supplies. Then, just as I was about to go to bed I found this guy, he was selling from a batch of CPU-onboard motherboard for 10 bucks each and everything clicked!

I did some quick calculations and decided I could probably gather enough cash to get: 10 motherboards, 10 2GB ram dimms, 10 Sata disks and 14 PSU (in case some fail) and some misc hardware for networking and such.

So... Long story short, I am going to build a cluster computer, the first version is going to have 10 nodes and I am waiting for delivery right now!

Gotta make a decision matrix like the one in the picture. It's for a recommendation report concerning whether or not to distribute laptops to the CSCE students at my university and what kind of laptop if so.

I need help determining the weights for my matrix, because my personal preferences may not reflect the majority. As a programmer, how would you weigh the following three (very broad) categories?

Power(CPU, GPU, memory, HDD, I/O, etc..)
Quality (Durability, material, aesthetics, etc..)
Comfort(Weight, size, shape, keyboard, screen-eye comfort, OS familiarity, etc..)

Please write an integer 1-10 in the following format:
Power/Quality/Comfort ex: 7/4/9

Thanks, everyone!

I am sick of misrotated videos.

Sometimes, the phone camera software saves a video vertically because the user hits "record" before the software has detected that the user is holding the smartphone horizontally, because the software stupidly launches in vertical orientation by default.

So the software wants the user to wait until it has finally detected horizontal orientation, which causes the user to miss out on a moment.

How about the camera software actually saves the video in the orientation it was recorded in for the most time, rather than only the beginning of the video?

If I can think of this idea, billion-dollar companies surely can.

In the meantime, misrotated videos can be fixed using this ffmpeg command on Linux or Windows:

ffmpeg -i input_file.mp4 -metadata:s:v rotate="0" -c copy output_file.mp4

And if the phone was held with the home button to the left side:

ffmpeg -i input_file.mp4 -metadata:s:v rotate="180" -c copy output_file.mp4

This solution is superior compared to using -vf (video filters) because it only touches the metadata of the video. No re-encoding. This means no quality loss and no CPU/GPU power needed to process the video again. It just passes through.

What was supposed to be a simple HDD to SSD upgrade for my brother ended up taking 3 fucking days.

His computer's idle temp was fucking 90c because of fucking YEARS worth of dust preventing fans from breathing, one of them was even dead so I had to go to best buy to get a new one.

Had a power outage happen in the middle of cleaning the damn dust out before replacing the bad fan. It took close to 24 hours for it to come back, and I just didn't bother until the day after cause fuck that.

When I go back to it, I finish cleaning the dust, clone the old HDD to the new SSD, do the swap out, replace the thermal paste on CPU cause why the fuck not at this point. Then turn it on to test, yeah from 90c down to 20c : |

Yeah... so I charged him for the new fan, and the hour-ish it took me to clean the damn dust and replace the fan... (drive was agreed to be done for free as a favor) Yeah not really worth charging for but I was pissed and that was the 'nicest' way I could show how annoyed I was with him not properly caring for the PC. Like honestly 90 degrees celsius. I refuse to believe he didn't notice impacted performance in his games

So happy about being about to convince management that we needed a large refactor, due to requirements change, and since the code architecture from the beginning had boundaries built before knowing all the requirements...

pulled the shame on us, this is a learning lesson card.. blah blah blah

Also explained we need to implement an RTOS, and make the system event driven... which then a stupid programmer said you mean interrupt driven ... and management lost their minds... ( bad memories of poorly executed interrupts in the past).... had to bring everyone back down to earth.. explained yes it’s interrupt driven, but interrupt driven properly unlike in the past (prior to me)... the fuck didn’t properly prioritize the interrupts and did WAYYY too much in the interrupts.

Explained we will be implementing interrupts along side DMA, and literally no message could be lost in normal execution.. and explained polling the old way along side no RTOS, Wastes power, CPU resources and throws timing off.

Same fucker spoke up and said how the fuck You supposed to do timing, all the timing will be further off... I said wrong, in this system .. unlike yours, this is discreet timing potential and accurate as fuck... unlike your round robin while loop of death.

Anyway they gave me 3 weeks.. and the system out performs, and is more power efficient than the older model.

The interrupting developer, now gives me way more respect...

Can't wait until I'm done at my current workplace (about a month left). I've had enough of this fucking shitty ass ancient ASP.Net ERP-system and employer.

For the system:
1. The build times are horrendous and eats up all CPU power.
2. The "classic" UI and UX is absolute garbage. If I was an accountant, I would go nuts trying to invoice someone. Companies pay millions to use this garbage.
3. Besides the "classic UI", there is a mishmash of different JS frameworks plastered on top.
4. Absolute no fucking technical documentation whatsoever
5. The in-house relational database is a mess, no relations, entirely denormalized, no documentation.
6. The frontend is structured in HTML tables with iframes inside <td>

The company:
1. If you're a implementation consultant and you quit your job, you get stripped off all your projects, you won't get to join anything social and you're placed on 1st line support for three months. They might as well force them out.
2. Anyone can work from home anytime they feel like it without any valid reasons, and believe me they do.
3. The senior devs are overworked as all hell. By the end of the year, some of them have hundreds of flextime hours and won't get anything in return.
4. The CEO seems like a jolly guy, but when you quit, he doesn't like you at all. He also acts like a bigshot, always getting driven around meetings when there is literally a very good metro network in this city.

Here, a full retrospective of my Apple products ownership.

iPhone SE – after Android, I was absolutely amazed by how fast it worked. No UI lags, camera works absolutely instantly no matter the light conditions, all the GPU-heavy games work butter smooth.

After camera and charging port failures on Xperia flagship and CPU literally melting through screen rendering it unusable on Meizu, it was enough to make me interested in Apple products.

When I was using Meizu, I actually got a twitching eye which was triggered by UI lags. After two months of using iPhone, I noticed that something was missing – my eye wasn't twitching anymore.

iPhone actually cured me.

MacBook 12 – a 900 grams laptop with passive-cooled mobile CPU running many Chrome tabs, heavy Webpack HMR build, VSCode and Slack just fine. Yes, you can't play games, but I don't even require it from a laptop this tiny.

Butterfly keyboard that internet hates so much actually increased my typing speed and comfort compared to MX Red mechanical keyboard, and ForceTouch trackpad made me forget about mouse. I learned how to disassemble the Butterfly keyboard if I ever need this but the keyboard never failed.

I use this laptop to this day and it still even smells like the day one, a beautiful smell of a new Apple product.

iPhone X – got it because of the camera, stayed for great battery life and amazing OLED display. I use telephoto lens exclusively and it made me lay off my Canon DSLR with Helios lens which stays on my bookshelf covered in dust to this day.

True black of OLED display which is undistinguishable from the screen bezel is stunning. To this day, battery surely works for one and a half days and I watch youtube really often.

I sometimes struggled to unlock iPhone SE with wet fingers, but with FaceID, as soon as I look at the screen the phone is unlocked. Works perfect every time, never had an issue with this.

Stainless steel body feels premium compared to aluminum. Stereo sound is a major selling point if you're like watching videos and playing games on your phone. Overall amazing product and a huge improvement over SE.

Apple Watch series 4 – really comfortable fit. Nice battery life, once I forgot about it for like ten days during lockdown and it was still working, even though on power reserve mode. Really reliable in terms of battery life and liquid protection. Very satisfying Taptic Engine crown clicks. I run every day and Apple watch always measure my heart rate correctly, and the running app is well designed and a pleasure to use. Overall a nice accessory to have if you use iPhone.

Powerbeats Pro – great sound and battery life. I switched from Shure SE215 which was great, but it had wires. I listen to a lot of music so the sound quality is important for me. When I was choosing earphones I visited a store where you can listen to them all. I listened through earphones like Noble Audio Kaiser Encore and JH Audio Layla, and of course $4000 Laylas sound better than $249 bluetooth earphones, but the difference in sound doesn't justify the difference in price to me.

Powerbeats pro is the Apple H1 chip true wireless earphones with largest driver of them all which makes them sound better than AirPods Pro – it's just physics. Bass in Powerbeats is amazing, which is also true for my Shures, but Powerbeats also win in clarity.

It connects seamlessly to both my MacBook and my iPhone, and everyone in voice chats can hear me really good.

Huge case is a major throwback compared to AirPods, but the battery life of earphones themselves is so great that I just leave the case at home and only carry earphones and it works for me.

Apple Link bracelet in space black – really better than I expected. Intricate detailing, literally the steel that Rolex uses, top-notch finishing and polishing – all that for just 450 dollars. I only used it for several days now, but it already feels like a really satisfying product.

Before all that I was using Linux. It took a year for elementaryos devs to fix wifi for my laptop. Ubuntu looks and feels ugly. Pop OS felt like garbage. Manjaro was also just that – garbage. KDE Plasma – I don't even want to talk about that. A monstrocity where you accidentally click a wrong switch in the settings and your system won't boot up again. Also, PulseAudio. Struggles with proprietary drivers and software updates.

Windows? I serviced a lot of Windows PCs through my career and it never, never worked as intended. I'm no dumbass, I always managed the rights correctly and never installed sketchy apps. My latest ryzen gaming build with a lot of ram also lags somehow even in Windows 10 UI.

Before I switched, I defended Linux.

My life was a lie.

I'm sorry to everyone who I offended based on their opinion on Linux.

Just discovered Roccat Power-Grid!
It's so awesome and useful!
Mapped all Makros I use while programming to it.
I also have some CPU/RAM info and media buttons (play/pause/next/...).
You can even add website buttons. For example for Github or Stackoverflow!
Not sure if it's faster to use it but it's way cooler :)

Check it out!
Just search for it on Google/DuckDuckGo.

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...

So today my company was removing most workspaces with USB 2 connections, DP cables and magsafe 2 power cables. This means that my MBP mid 2014 can't connect to the keyboard and monitors anymore. It already struggled with 4K, so my 2K options were already limited, but now the last few spots are mostly gone. In short: I'm being forced to upgrade.

But tell you what: I don't want to. It feels like a waste to recycle my laptop (even if it's company paid and owned) while it's perfectly acceptably fine. And mind that I will get the latest and greatest i9 for free. Yes, that overheating, throttling failure of hardware design piece of shit. 2 coworkers already own the beast and confirm that it gets really hot really quickly. One of them even has daily crashes (the laptop just turns off) and random reboots. A total waste of money. And my future time. As if it's not enough work to migrate to a new laptop (even with Time Machine).

So, fellow ranters, what do I do? I hope I can leverage the second best MBP (CPU-wise) from this situation, unless there already is a bunch of i9s in the office ready to be used. I really, really don't want one. And I think my current computer is great for what it is, even if it's old. It's a really pro machine for my needs (I'm very efficient, except for Android Studio).

I even consider asking for a Linux machine, but then a whole new world opens to me that may be a step too big (since I barely have hands-down experience).

Enlighten me with your ideas, muggles!

I make a mistake today.

The incident happens when I opened my computer, open Vivaldi, and after all tabs are loaded, I update my Linux distro.

Unfortunately, when it updates the kernel, it got lagged, really lagged. My CPU load goes up to 14,56 (which is also the PB of CPU load of my computer). I barely can move my mouse. I decided to Ctrl-C, nothing happened. Then I decided to turn off my computer by pressing the power button once, nothing happened. Then I hold the power button for a few seconds, don't really hesitate or think of anything.

When I start my computer again, it goes to the GRUB. I realized that the GRUB load is slower than usual, but I don't really think of anything. When I choose the 'Alter Linux' option (which is the name of my distro), the GRUB says that it cannot find the kernel and thus it cannot boot. At this point it's pretty fucked up.

2 lessons that I have learned after this incident:
1. Turn off every single other window (except the Update window) when you are going to update.
2. Never turn off the computer while it's still updating, especially if there is kernel update in it.

(Luckily, I have an old version of the distro burned to a Kingston USB, so I can run the live environment of the distro from the USB, and then install another distro to that USB)

Decided to open htop in another terminal window while running a small python script on my works server.

I started running a Database benchmark yesterday morning, with my system configuration, expected time to complete was 36hrs(arround), so I left it and made sure no one disturbs (I stuck a note in the monitor) because it was on common system in the lab.
Then I went to my other work.
Evening ,I came to check the progress, my monitor was switched off, I thought its in power saving mode!
Fuck, I bend down and see the CPU is off!
Wtf!! Who shut it down ,even after the note.
Then I saw the electric outlet was off!
Then after wards asking ppl in the lab, they told ,the cleaning person was cleaning the switches, so yeah she could have by mistake!
* I facepalmed *
So again, I set it up with frustration!
Today morning ,I came to see the progress
FML, from no where ,
" It's in Windows automatic repair loop! "
It's been 3hrs, trying to get out of that loop without loosing the data.
1TB of data is there, took 1month to setup all the things
Fuck Microsoft for adding these kind idiotic stuff in windows.

Is there a spirit in the lab not allowing me to do benchmark?

7:37 PM here, it's very very hot and I'm warming like a fuckin' AMD CPU

@th4t is now running in low power

Hey guys,
I was wondering what setup (especially laptop/tower) you would use for coding at work it you could chose freely (I know some of you can).
I like the Lenovo thinkpads and like to have at least 16gb of ram (32 are better) and some powerful cpu like an i7. Usb type c, power delivery and useful Linux driver support are must-have.

How about you?

Sigh...this is kinda stupid.

I'm getting a new ThinkPad at work after 4 years. At first I was like "oh yeah...a new machine!". But they are replacing my quad core T540p with a dual core T560. The T560 CPU has a 30-40% less multi core benchmark score (surprise).

So...dear IT: We are not a small 50ppl company that builds some console apps or small shiny hipster web sites. We are developing fucking large business applications with dozens of projects. Our IDEs and our compiler platform are benefiting from raw CPU power and multiple cores. So can I pls not getting A FUCKING DOWNGRADE AFTER >4 YEARS FFS? THANK YOU!

(before anyone asks: keeping the current notebook is not an option because of warranty/support contracts)

I hate the feeling when the processes maxing out all my cpu cores are processes I thought were long since terminated. I guess even when I rm -f I don't really let go and still have the tar.gz in the back of my mind somewhere, and somehow zcat pipes those seemingly tidy archives all over my cwd at the worst possible times like some systemd transient timer that I can't recall the syntax to check... This is when the shell becomes unresponsive and I can't cd away, or even ps aux | grep -i 'the bad thoughts' to get their pid to figure out why this is happening again. Is it really time to hold down the power button? I'm so afraid of loosing unsynced data, I'll wait a little longer...

What tools do you have access to at work?

I don't work a tech company, far from it. I love it but both the hardware and software at my disposal are so shitty I'm starting to lose it.

Running Windows locally, I'm not allowed any Linux distro because "security." Indeed, I don't even have admin rights on my machine. It was rejected. The excuse being that I am sudoer on a server, which (and can only be) physically located in our headquarters.

Today I found out this server's CPU from the dark ages does not support tensorflow, so here I will be building that shit from source tomorrow (no GPU of course).

And thanks for 4G of RAM on what you refer to as a "power" machine.

Fucked up my old phone (picked up an overheating phone with super cold hands and the screen exploded) and my new one is way faster despite having almost exactly 1/2 the CPU power (8-core 2.13GHz in old, 4-core 1.4GHz in this one) due entirely to the Android build not being dogshit. They both only have 2GB of RAM, so i'm still sitting at like 300MB of free RAM with nothing running, but it's a start.

They dont mention it in any reviews but dell has cooling problems. Yesterday I bought a brand new g5 from a shop and fans were not spinning until 80c from which it started spinning at 4900rpm like a vacuum. Note that I have latest bios so its not temperature table problem in bios.

I found out that there is a driver for thermal power which you can install and for most people it does the work (runs 2200 rpm silent cooling for most of time and 4900 rpm when cpu gpu temp goes above around 60c which is annoying)

So I had to spend entire day on figuring out how to control cooling fans myself. And even then dell limited available speeds in bios at 0, 2200 and 4900 rpm.

Anyways now my cooling fans run at 2200 rpm until 70c and 4900 after. So i get some nice silent performance for 90% of what I do and as for gaming, full fans after 75c is fine. I ran DOOM from steam and max temps Ive got were around 85-90c which is pretty high, so Im thinking of doing a repaste event though im afraid of voiding the warranty.

This happened to me sometime back.

I want to try out a WordPress plugin in my local machine before installing on a production server. It is an Ubuntu machine. Downloaded and installed Xampp, then setup WordPress with MySQL. Now tried uploading the plugin zip file, it throws some permission error, asking to fix permissions or use FTP. I thought of just chmod 777 recursively for the WordPress directory to fix this easily.

Ran the command, looks like it is hung. Terminated using Ctrl+C and then ran the same command. Again it is taking much time. It should not take so much time to recursively change the permission of just a WordPress directory. Thought something was wrong. Before I realized the damage is already done.

Looks like I ran the command

sudo chmod -R 777 /

instead of

sudo chmod -R 777 ./

Fuck, I missed a dot in the command and it is changing permissions of everything in my machine. Saw the System monitor, CPU usage spiked to 100%. I can't close or open any program. Force shutdown the machine using the power key. It didn't boot again. Recovery mode didn't help. Looks like there is no easy way to restore back from this damage. Most of the files I need are backed up in the cloud, still, need a few more personal files so that I can format and reinstall Ubuntu. Realised I have Windows in dual booting. Boot into Windows and used some ext4 reader to recover the files, formatted and reinstalled the OS. Took a few hours to get back to my previous setup.

Lesson Learned: Don't use sudo unnecessarily.
Double check the command while executing.
Running a wrong command with root permission can fuckup your entire machine.

Is anyone on here a proud owner of one of the current gen enthusiast platforms? (Threadripper or i9)

I am seriously wondering how much impact that brute power has on my build times. I just tried a ramdisk for my maven build and it seems that the faster storage did not increase build times much. So I am assuming there is a cpu bottleneck?

Keyboard, mouse, cpu, monitor, extension power cable😂

This is a massive tossup between RandNoRepeat( from TI-BASIC (returns an int between 2 passed params but tracks what's been given from that range this power-on, meaning if the range is too low IT ENDS UP HANGING THE FUCKING CPU IF YOU RUN OUT OF NUMBERS and it also rolls over and over so it's slow as shit in general) or Python forgetting how the fuck if statements work.

I'm fucking tired of my computer having random
2 seconds latency on any basic action and being slow as fuck regardless of powerful processor, ssd and 32GB RAM. Music via bluetooth is basically unusable since every few seconds the music stops for a 0.2s then plays again. I installed this system (opensuse tumbleweed) in February this year and it's just sad that I have reinstall again (any ideas for distro) ?

I made a dummy mistake of buying a CPU without internal graphics and this resulted in having to buy a GPU. So I got myself Nvidia(another mistake) since i though i would be using CUDA on the university. Turnes out CUDA cannot be installed for some retarded reason.
With Nvidia GPU the screens on my two monitors are swapping every time I use a hdmi switch to use other computer. On AMD GPU this problem does not exist. AMD GPU pro drivers are impossible to install. Computers barely fucking work, change my mind. Shit is breaking all the time. Everything is so half assed.

The music player that i use sometimes swaps ui with whatever was below it like for example the desktop background and i need to kill the process and start again to use the program. WTF.

Bluetooth seems to hate me. I check the bluetooth connected devices on my computer, it says headphones connected. BULLSHIT. The headphones are fucking turned OFF. How the fuck can they be connected you dumbass motherfucker computer. So I turn on the headphones. And I cannot connect them since the system thinks that they are already connected. So I have to unpair them and pair them again. WTF. Who fucking invents this bullshit?
Let's say i have headphones connected to the computer. I want to connect them to phone. I click connect from the phone settings. Nothing happens. Bullshit non telling error "could not connect". So I have to unpair from computer to pair to phone. Which takes fucking minutes, because reasons. VERY fucking convenient technology.
The stupid bluetooth headphones have a loud EARRAPE voice when turning them on "POWER ON!!! PAIRING", "CONNECTED", "DISCONNECT". Loudness of this cannot be modified. The 3 navigation buttons are fucking unrecognizable so i always take few seconds to make sure i click the correct button.

Fucking keyboard sometimes forgets that I remapped esc key to caps lock and then both keys don't work so i need to reconnect the keyboard cable. At least it's not fucking bluetooth.

The only reason why hdmi switches exist is because monitor's navigation menus have terrible ui and/or infrared activated, non-mechanical buttons.
Imagine the world where monitors have a button for each of it's inputs. I click hdmi button it switches it's input to hdmi. I click display port button - it switches to display port. But nooo, you have to go through the OSD menu.

My ~ directory has hundred of files that I never put there. Doesn't feel like home, more like a crackhead crib.

My other laptop (also tumbleweed) I click on hibernate option and it shuts down. WTF. Or sometimes I open the lid and screen is black and when i click keyboard nothing happens so i have to hold power button and restart.

We've been having computers for 20 + years and they still are slow, unreliable and barely working.

Is there a cure? I'm starting to think the reason why everything is working so shitty and unreliable, is because the foundations are rotten. The systems that we use are built with c, ridden with cryptic abbreviated code, undefined behavior and security vulnerabilities. The more I've written c programs the more convinced I am, that we should have abandoned it for something better long ago. Why haven't we? And honestly what would be better? Everything fucking sucks. The rust seems to be light in the tunnel but I don't know if this is only hype or is it really better. I'm sure it can't be worse than c or c++. Either we do something with the foundations or we're doomed.

My current "file/media server" is a crappy old falling apart windows box with a stupid mismash of internal and external drives with no redundancy. That sucks for a number of reasons, so planning on dropping around a grand or so (including drives) on doing it properly.

Space requirement would be around 20TB-ish of usable space, with 1 disk's worth of redundancy. That can include a newish 5TB drive I have lying around however. Would also run either Plex / Jellyfin, so some horsepower for transcoding would be nice (but no need for more than a single 1080 stream at once.) 24/7 operation, so don't want anything too power hungry.

Current (loose) thinking on the hardware side is an AM4 board and a reasonably low end CPU, 3x8TB WD golds. Software side, probably CentOS, then mergerfs + snapraid. Anyone got any insight as to other options? Hardware not my speciality in particular, so open to suggestions.

-- Have you ever self hosted a Linux/Free Bsd server at home?
-- What was the maintenance like in terms of operation and cost compared to an online service?

I and my partner are planning to self host our Ubuntu server locally because currently though we spend less than $1100 a month on Azure with moderate CPU usage but we plan to scale out with believes that the server cost might sky-rocket.

We made a budget of $25k for the setup which includes cost of hardware, bandwidth and power.

We also made some research concerning most used hardwares for home servers because we really are newbees talk of hardware. What we found are options related to the Intel Xeon as CPU, some others say use NAS, while some are more of advertising.

$25k on the desk,
we care more about speed than of space. How can we make the setup totally worth it? You don't have to spare us a change, just some headlight and way to go.
Your advice are needed. Thank you.
