So my USB DVD drive needs more power than a normal USB port can deliver.
Normal Person: I'll bring it back to the store and get a diffrent one.

Me:

6pm - arrive home from work, log into my computer and start working on side projects.

4am - Finally go to sleep after staying up all night setting up arch in a vm.

7am - Start drive to work in the snow and ice.

7:20am - car runs out of wiper fluid.

7:30am - round corner so that I’m driving towards the sun, windshield is covered in mud and I have 2% visibility.

7:35am - take off ramp towards gas station so I can buy fluid and wash window.

7:36am - Car mysteriously parked in center of off ramp, nearly smash it but have a narrow miss.

7:40am - can’t find the freaking pully in new car to pop hood

7:41am - found it.

7:50am - drove the back way to work because it cuts out traffic, but includes many steep hills that I forgot existed, come to a skid at bottom of one and am pushed out into the main road, luckily nobody is coming and I’m able to continue on my merry way.

8:01am - sit down in desk, lead staff person comes over evoking Lumbergh from Office Space and lets me know I need to be on time to work and that the snow doesn’t give me an excuse. I agree and smile and suck up and he leaves.

8:02am - pull out phone to write down notes about personal project that I thought of on drive here, phone dies. I forgot to plug it in last night.

8:04am - found power bank charger thing in desk but it uses a micro-b type usb and I only have usb type c on me.

8:10am - borrow usb from old headset in office surplus.

8:11am - writing notes. Have sudden realization that I didn’t shut down my vm and that when my computer went to sleep and subsequently locked it probably halted virtualbox and everything would be lost for the second time.

8:12am - got on devRant.

Went to go help someone with their wireless printer.

Client: my printer doesnt work.

Me: okay let me take a look at it.. (took a look at it and saw the power core wasnt plug in)
So it seem like you forgot to plug in the powercord. Do you by any chance have it with you?

Client: well it said it was a wireless printer so i didnt think i would need it. I threw it away.

Me: well yeah wireless as in you dont need a usb core to connect it to your computer you can just do it through wifi.. but it needs a power source in order to turn on..

Client: well then why did it said that its a wireless printer if it needs a cord? Thats false advertisement.

Me: Sir the printer is a wireless printer but you cant get power wireless you need a power source in order to turn on the printer.

Client: you probably dont know what youre doing.

Me: *its okay hes only 79 years old*

Long rant ahead. Should take about 2-3 minutes to read. So feel free to refill your cup of coffee and take a seat :)

It turns out that the battery in my new Nexus 6P is almost dead. Well not that I didn't expect that, the seller even explicitly put that in the product page. But it got me thinking.. why? Lithium batteries are often good for some 10k charges, meaning that they could last almost 30 years when charged every day! They'd outlive an entire generation of people!

Then I took a look at the USB-C wall charger that Huawei delivered with this thing. A 5V 3A brick. When I saw that, I immediately realized.. aah, that's why this battery crapped out after a mere 2 years.

See, while batteries are often advertised as capable of several amps (like 7A with my LiitoKala 18650 batteries that I often use in projects), that's only the current that they can safely take or deliver without blowing up. The manufacturer doesn't make this current rating with longevity in mind. It's the absolute maximum in current that a given battery can safely handle.

The longevity on the other hand directly depends on the demand that's placed on the battery. 500mA which is standard USB 2.0 rating or 1A which is standard USB 3.0 rating, no sweat. The battery will live for at least a decade of daily charges and discharges like that no problem.

But when you start shoving 3A continuous into a battery, that's when it will suffer. Imagine that your current workload is 500mA and suddenly you get shoved 6 times that work upon you. How long would you last?

Oh and not only the current is a problem, I suspect that it also overvolts the battery to maintain a constant current all the way till the end. When I charged my lithium cells with my lab bench power supply, the battery would only take a few milliamps when it got close to the supply voltage. Quick bit of knowledge: lithium cells are charged at constant current first, then when the current drops below that, it continues at constant voltage - usually 4.2 or 4.35V depending on the battery. So you'd set your lab bench power supply at 4.2V 500mA. But in that constant voltage mode, as the battery's voltage and the supply's voltage equalize, the current drops because the voltage difference becomes lower. Remember, voltage is what causes current to flow. Overvolting at the supply to stay in constant current mode all the way till the end speeds this process up but can be dangerous and requires constant monitoring of the battery voltage.

So, why does Huawei and a bunch of other manufacturers make these 3A power chargers? Well first it's because consumer demands ever more, regardless of the fact that they can just charge at 500mA for the night (8h of sleep) and charge a 4000mAh battery from 0 to 100% no problem. Secondly it's because sometimes you need that little bit of extra juice fast, like when you forgot to plug the damn thing in and you've got only 30 minutes in the morning to pour some charge into it.

But people use those damn fucking things even when they go to bed, making that 3A torture a fucking standard process!! And then they complain that their batteries go to shit?!

Hopefully this now made you realize that the fast charger shouldn't be used as a regular charger ^^

New job, started two months ago. Forced to use a MacBook. First time using iShit in my life.

- Laptop reboots randomly every three weeks or so "because of an error" (thanks, very informative error message).

- Sometimes if I use two screens and I lock my laptop, only one screen gets locked.

- The most simple tasks require a fucking large number of clicks. There are almost no keyboard shortcuts. My hand hurts because of this, and after two months the pain is getting worse and worse.

- Yes, I know there are apps that give you extra keyboard shortcuts, but those don't help much. I never used a mouse in 10 years.

- Window management sucks. It's so broken and poor in so many ways, I don't know where to start.

- Random errors and pop-ups are the norm.

- I have only four fucking USB Type C ports. I can somehow understand having only Type C because it looks cool, but fuck at least give me 6 of them, or 8. Do you really have to force me to use a USB hub, in addition to a shitload of adapters?

- Multiple monitors don't work unless the laptop is connected to the power adapter.

- The above point means, in practice, that I have exactly zero USB Type C ports available to me: one is used for the power adapter, two are for the two monitors, and one for the USB hub. Whenever I have to connect something that has Type C, I have to choose between monitors and going fuck myself.

- I don't want to comment on performance, cooling system or battery life. This would be a waste of time. Let's just say that it's shit.

Now, dear Apple fangirls and fanboys, please downvote this rant. I want your downvotes, so please don't hesitate to press that (--) button. But please let me say that these products are shit, pure shit. Fuck Apple and their overpriced products.

I recently learned why you shouldn't delete your linux partition by just pressing the 'delete volume' button.

I currently own a SP3(i7, 256gb).
I got bored of windows and installed Linux Mate. It ran quite fast and snappily. All was good.

Then I looked on the internet. Apparently fedora runs really well on the SP3. So I deleted my Linux partition by pressing 'delete volume'.

Turns out, thats a bad idea. Grub was in that partition, so when I restarted my tablet, it booted into the 'grub rescue>' prompt.

After messing around, I finally found that pressing the Volume Down button and power button at the same time seemed to boot into my Fedora Live USB.

All the while, I was quite worried I'd lost all of my assignments(I knew I could have used the minitool of gparted live cd).

Finally I got it to install, and all was good again. Has anyone else made this mistake?

Good morning everyone^^
I just heard my company is doinig some weird shit.
1. We RECOMMEND doing backups on a USB stick (our customers get a cheap giveaway when they purchase our products).
2. We sell farm controllers with less power than a fucking arduino as "Top Notch technology". (single core 1Mhz, 128MB RAM)

We Devs are not supposed to understand this logic. We shall only "make it faster". If proper solutions are suggested it gets shrugged off as "expensive".

TL;DR: check polarity before plugging your DIY circuits into others!!!

*goes off to watch some Lucky Star and drink some booze*
*notices phone battery dying after 3rd pint*

But my charging cable that Huawei delivered with this thing is way too short... Well that ain't no problem, I can make one of my own 😎

But I'm tipsy.. sound I really enter the workbench in this state?

*goes off to build a charging cable anyway*
But what was USB-A male connector's polarity again? Oh, there's the fan's USB connector that I've made in the past. Let's check on that one. So, left is positive and right is negative?

*solders the wires on*
Snip, strip, stick, done! Well that was easy. I guess that all those failed soldering attempts and lost pads in the past as a means of training did pay off in the end!

*plugs phone into Raspberry Pi media center through new charging cable*

Strange sounds coming from the speakers.. well that's odd. Reverse polarity or maybe the Pi can't handle a 1A load from my phone?

*plugs phone into the 5V 5A charging hub that I've made earlier*
That oughta do.. current limits should be no more in that thing.

*charging hub makes high-pitch noise similar to the Pi speakers*
Definitely a reverse polarity, isn't it :') let's check on the Gargler...
Oh shit! It is a reverse polarity mistake!!! Should've checked this earlier >_<

*resolders wires properly*
Alright, finally done.. as I'm writing this post, my phone's charging from the Raspberry Pi through my fixed charging cable now...

Lesson learned. Always check on the internet what the pinout is before soldering anything, don't solder while tipsy, and be fucking grateful that this phone has reverse polarity protection in it.

Nexus 6P with all its shortcomings regarding power delivery and battery management, luckily it's got reverse voltage protection features built-in. Otherwise it might've costed me my phone. Always double-check before plugging anything into something else!!!

You can kill me for this...
I've one old printer and and I wanted to print some pages. So I did following steps

1. Plugged printers power cable and turned it on.
2. Connected included cable to printer.
3. Opened PDF and tried to print
4. Did step 3 for fucking 20minutes

What went wrong?
I fucking forgot to connect USB cable to my fucking laptop. FML...

Technology never stops to amaze me.

I bought hdmi stick with nes emulator, connected it to power using usb on my tv directly no power adapter needed - only cable, it has 2 remote pads powered by batteries, all fits into my pocket and it has removable sdcard that I can connect to my computer and upload games.
I can go to someone’s house, bring up this little fella and we can play games together. It only took 40 years to do it.

Damn I remember playing, mario, contra or micro machines as a kid.

Spent 8+ hours playing great old games already lol.

I just need portable 60 inch tv screen or projection screen and battery that would power it for at least 8 hours and fit to my pocket and my life is complete.

Imagine you go to the bar, sit, grab a beer and play mario with random people all night.

Just disassembled 2 €5 desk fans because they were shit.. and so is their design apparently.

What I found inside was actually surprisingly simple.. a toddler could build it. It's just a DC motor, a 3PDT switch, DC barrel connector, some wires and screws to hold stuff in place. Oh and the plastic thingie with the fan blades, as well as the USB cable of course.

5 fucking euros. The combined cost of the components would be less than 3, certified motherfuckturers. Time to build it, injection moulding, transportation, sure.. but still.

And if you think that being salty about €5 is cheap shittalk, expand that to every fucking piece of electronics that doesn't cost a small fortune.. at all price ranges. Could be radios, alarm clocks, heck even phones. Shit's way too expensive for what it's worth. Perhaps because so many people in the industry are just here for a quick buck.. motherfuckers 😒

Anyway, back to the design.. the hole in the fan blade thingie is supposed to get the motor's shaft shafted in, to turn the blades. I'd use glue there.. but not these designers. They just shove it in and hope that friction takes care of everything. And one of the fan blade modules' hole was so wide that inserting the motor is like throwing a sausage down the hallway. No contact at all! Make it tight already like the Chinese designer's glory-...
Nah let's not get into Chinese tightness just yet.

Oh and also a resistor for slow mode. Consumes just as much power except the fan turns slower. Because fuck efficiency, right?

Goddammit, next time I'm just gonna build my own again.. at least that wouldn't be a certified piece of shit 😑

I just had a brainfuck moment...

Why do I charge my phone via PC USB at work (slowly) when I actually have a power bar on my desk...

Just now I realized that for some reason I can't mount SMB shares to E: and H: anymore.. why, you might ask? I have no idea. And troubleshooting Windows.. oh boy, if only it was as simple as it is on Linux!!

So, bimonthly reinstall I guess? Because long live good quality software that lasts. In a post-meritocracy age, I guess that software quality is a thing of the past. At least there's an option to reset now, so that I don't have to keep a USB stick around to store an installation image for this crap.

And yes Windows fanbois, I fucking know that you don't have this issue and that therefore it doesn't exist as far as you're concerned. Obviously it's user error and crappy hardware, like it always is.

And yes Linux fanbois, I know that I should install Linux on it. If it's that important to you, go ahead and install it! I'll give you network access to the machine and you can do whatever you want to make it run Linux. But you can take my word on this - I've tried everything I could (including every other distro, custom kernels, customized installer images, ..), and it doesn't want to boot any Linux distribution, no matter what. And no I'm not disposing of or selling this machine either.

Bottom line I guess is this: the OS is made for a user that's just got a C: drive, doesn't rely on stuff on network drives, has one display rather than 2 (proper HDMI monitor recognition? What's that?), and God forbid that they have more than 26 drives. I mean sure in the age of DOS and its predecessor CP/M, sure nobody would use more than 26 drives. Network shares weren't even a thing back then. And yes it's possible to do volume mounts, but it's unwieldy. So one monitor, 1 or 2 local drives, and let's make them just use Facebook a little bit and have them power off the machine every time they're done using it. Because keeping the machine stable for more than a few days? Why on Earth would you possibly want to do that?!!

Microsoft Windows. The OS built for average users but God forbid you depart from the standard road of average user usage. Do anything advanced, either you can't do it at all, you can do it but it's extremely unintuitive and good luck finding manuals for it, or you can do it but Windows will behave weirdly. Because why not!!!

I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3

Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.

I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.

So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.

So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.

That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3

Microshaft WanBLowS.

I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.

Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.

At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.

So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.

Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.

That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.

(looks like my rant is too long, continue in comments)

From 3 decades of operating system development, yesterday Windows shat itself (for the so many'th time) with the ACPI power button (how one can possibly fuck up interacting with a goddamn fucking pushbutton, I have no idea) and this morning I got back to my PC, only to notice that the USB driver (again one of the easiest and most ubiquitous protocols out there) shat itself as well. So wiggling the mouse to activate the screen? Of course, no says Windows. I can't possibly do that much, even though I'm developed by a team that could easily outnumber most distributions' development teams, and am part of a company that turns over fucking billions of dollars each year.

I feel that Microsoft offends the words "operating system" to the point that it should be changed (call me SJW 🙃), just for Windows. Shouldn't be too much of an effort considering that Microsoft never follows common standards anyway. I'd like to introduce you to the term "operating shitstain" 😜

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".

FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.

Well, I was Always into Computers and Games and stuff and at some point, I started wondering: "why does Computer Go brrr when I Hit this Button?".

It was WinAPI C++ and I was amazed by the tons of work the programmers must have put into all this.

13 year old me was Like: "I can make a Game, cant be too hard."

It was hard.
Turns out I grabbed a Unity Version and tried Things, followed a tutorial and Made a funny jet Fighter Game (which I sadly lost).

Then an article got me into checking out Linux based systems and pentesting.
*Promptly Burns persistent Kali Live to USB Stick"
"Wow zhis koohl".
Had Lots of fun with Metasploit.

Years pass and I wrap my head around Javascript, Node, HTML and CSS, I tried making a Website, worked Out to some extent.

More years pass, we annoy our teacher so long until he opens up an arduino course at school.
He does.

We built weather stations with an ESP32 and C++ via Arduino Software, literally build 3 quadrocopter drones with remote Control and RGB lighting.
Then, Cherry on the top of everything, we win the drone flying Contest everyone gets some nice stuff.

A couple weeks later my class teacher requests me and two of my friends to come along on one of their annual teacher meetings where there are a bunch of teachers from other schools and where they discuss new technology and stuff.

We are allowed to present 3D printing, some of our past programming and some of the tech we've built.

Teachers were amazed, I had huge amounts of fun answering their questions and explaining stuff to them.

Finally done with Realschulabschluss (Middle-grade-graduation) and High school Starts.
It's great, we finally have actual CS lessons, we lesen Java now.
It's fuckton of fun and I ace all of it.
Probably the best grades I ever had in any class.

Then, in my free time, I started writing some simple programs, firstvI extended our crappy Greenfoot Marsrover Project and gave it procedural Landscape Generation (sort of), added a Power system, reactors, Iron and uranium or, refineries, all kinds of cool stuff.

After teaching myself more Java, I start making some actual projects such as "Ranchu's bag of useful and not so useful stuff", namely my OnyxLib library on my GitHub.

More time passes, more Projects are finished, I get addicted to coding, literally.
My days were literally Eat, Code, sleep, repeat.

After breaking that unhealthy cycle I fixed it with Long Breaks and Others activities in between.

In conclusion I Always wanted to know what goes on beneath the beautiful front end of the computer, found out, and it was the most amazing thing ever.
I always had constant fun while coding (except for when you don't have fun) and really enjoyed it at most times.
I Just really love it.

About a year back now I noticed that I was really quite good at what I was doing and I wanted to continue learning and using my programming.
That's when I knew that shit was made for me.

...fuck that's a long read.

My brother came to me with his phone today to ask me if I could turn it on with my computer, because his power button is broken so I proceeded to attach it to my lappy and boot it with adb just to find out I can't do anything because he hasn't turned on USB debugging!
I managed to get into his recovery which helped nothing because in order to navigate in the menu the power button has to work
Uuuugh I hate this ...

I just bought a USB mobile power pack... Here my thought:

-It's on sale!
-But do I really need it?
-.... Will I could give it to my dad if I don't...
-but what it's it been... Chinese products are cheap...
-this isn't cheap... It's just on sale!
-hm....
-you know you'll need it.. at the rate my phone's battery gets used in a years time it won't be able to leave half a day...

It's not too late to cancel.... Should I cancel?

Shootout to my 2.5GB Maxtor hard drive, that I heavily used between 1997 and 2001. There were no USB drives, and CD burners were too expensive for consumers. So I used to open my PC case, remove the drive (along with Windows and my software), bring it around at my friend's house and have fun while copying hundreds of mp3s, patiently downloaded from filesharing and 56k modems or ripped from CD audio, in and out.

One time it fell out from my desk, hitting hard floor big time. I thought I lost it forever, and basically my whole PC in it. Then I tried plugging again its IDE and power connectors, and it was still working! ... well, half of it. That badass still continued to work with one of its two platters crashed, and got some more mp3s with it.
Maybe I still have it...

Gotta love Linux!

Wanted to install Arch on my Rasperry PI yesterday, but don't have a cardreader on my PC. Still had an SD with a different distro (RasPlex) lying around. Popped that in, connected power and ethernet only, looked up the default SSH credentials and got to a blinking terminal on my desktop PC.
Well, how am I gonna format my microSD? Rasplex comes without fdisk, and I booted it from the only microSD slot.
Well, here we go - Extracted arch to a usb thumb drive, chrooted into it, switched microSD cards, partitioned and formatted it from the USB-Arch, installed Arch on it, chrooted from Arch to Arch (😁), set up drivers, network and ssh access, rebooted to my why-the-hell-not distro.

Everything worked!

Got my first soldering project working. Looks trash and horribly done but it does power the RPI from my 3d printers power supply using a buck converter to drop the voltage

Thankfully I got 2 pack of the usb c breakout boards. The first attempt is horribly mangled 😅😅😅 did i mention i suck. Lol

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...

Windows 10 wanted to restart my XPS due to some updates, said will do it during idle hours but I still restarted. Boots back , couldn't. Tried again, same. Removed all USB devices , HDMI monitor, mini display monitor , still no luck. Removed power cable & it starts.

Slowly and carefully added all back one by one. Working for now ...

am i missing anything?

Well, it took me 7 hours but I finally made it.

I have a functional Arch Linux installation on my new laptop.

oh except the audio fails from time to time but it'll work eventually
and my hard disk starts clicking whenever I reboot even though I keep disabling its "power management"
and for fucks sake will you please mount my usb when i tell you to
and my touchpad doesn't work

but I can code and play games on it so whatever it's functional

Hey guys, wanna install Linux first time, but had some doubts.
Config - core 2 duo 2.93GHz, 2GB ddr2 ram, 320 hdd, AMD graphics card.
Doubts :
1. After writing it on usb and setting it in usb boot mode, the system didn't read the pen drive data ... is it because of the writing software ... I used power iso.
2. What about the partitions ? Do they still remain and will the install guide only ask to format the c drive or the whole hdd ?
3. Which distro do y recommend... I had kali/debian/fedora/mint in mind
My friends complained about fedora taking 45 seconds to boot up, I don't know about the other distro's ..
Thanks in advance

So last week I got my second 3D printer. I have done a few prints with it and this weekend I wanted to connect it to an Octoprint instance on my Raspberry Pi. Yesterday everything went great, got some plugins installed, changed all settings within octopi, connected it to my network and this morning I thought let's connect it to my printer and try to print something with it. But everytime I executed my gcode it gave an error about the heated bed not being able to heat up. Even though I did see all communication between the printer and octopi, on both ends.
I've disassembled the build plate to see what could be causing the heating issue. Did not see anything. Strange...

I assembled the whole thing again and then turned on the printer and tried printing again. Hmm, now it does work, why? Me thinking a bit and then realizing that before I didn't hit the power switch on the printer and apparently the Pi gave enough power through USB to turn on the display and do basic logic like doing beeps on touches and changing variables on the screen. The worst thing is that octoprint gave me warnings about low voltage on the Pi even though I was using the official Raspberry Pi power adapter...

Dear laptop vendors, stop wasting so much precious device estate on nothing!

This wasted physical space could easily fit in six USB ports, or four USB ports and two HDMI ports, or four USB ports and one HDMI and one LAN. Or four USB ports and two SD card slots.

> "Who the heck needs 6 USB ports?"

You don't need more USB ports… until the day you do need them comes.

> "HDMI and LAN are feature creep!"

It's "feature creep", until you need it.

> "Ever heard of USB hubs?"

While better than nothing, they are tedious to carry around and can hardly support more than one external high-power device such as an external hard drive or blu-ray drive, except if you have an external power adapter, which is even more tedious to carry.

Also, have fun closing programs until the operating system stops whining "volume is busy" just so you can unmount your external SSD and then reconnect it through a USB hub. Sounds like fun, huh?

You were playing audio from your external SSD? Too bad. Now you need to close the media player to be able to unmount the SSD, then later restart it and seek the last position. And all of that could be avoided if your laptop happened to have one more USB port.

...Aaaand it's built!
Couple problems though:
- The power supply has massive coil whine when the computer is shut down
- I can't seem to get a windows installation on my USB drive

Stories like the one I'm about to tell you are just another reason why people hate Windows. I know I usually preach 'Don't hate everything' and shit, but this is a real big fucking deal when it hits your desktop for no reason.
Now, onto the actual story...

Background: Playing with my Oculus, fixing issues like forgetting to use USB3 and stuff. I learned about an issue with Nvidia GPUs, where in Windows, they can only support 4 simultaneous displays per GPU. I only have the one GPU in my system, Nova, so I have to unplug a monitor to get Oculus and its virtual window thingy working. Alright, friend gave me idea of using my old GPU to drive one of my lesser used monitors, my right one. Great idea I thought, I'll install it a bit later.

A bit later...

I plug the GPU in (after 3 tries of missing the PCI-E slot, fuckers) and for some reason I'm getting boot issues. It's booting to the wrong drive, sometimes it'll not even bother TRYING to boot, suddenly one of my hard drives isn't even being recognized in BIOS, fuck. Alright, is the GPU at least being recognized? Shit, it isn't. FUCKFUCKFUCK.

Oh wait. I just forgot the power cable Duh. Plug that in, same issues. Alright, now I have no idea. Try desperately to boot, but it just won't I start getting boot error 0xc000000f. Critical device not found. Alrighty then. Fuck my life, eh?

Remove the GPU, look around a bit while frantically trying to boot the system, and I notice an oddly bent SATA cable. I look at it and the bastard is FRAYED AT THE END! Fuck, that's my main SSD! I finally replace the SATA cable and boot, still the same error... Boot into a recovery environment, and guess what?

Windows has decided to change my boot partition, ya know, the FUCKING C: DRIVE, from NTFS to RAW format, stripping it of formatting! What the actual fuck Microsoft? You just took a shit on yourself while having a seizure on the fucking MOON! Fine, fuck you, I have recovery USB! Oh, shit, that won't boot... I have an old installation! Boot ITS recovery, try desperately to find a fix online... CHKDSK C: /F... alright, repairing, awesome! Repaired, I can see data, but not boot. So now I'm at the point where I'm waiting for a USB installer to be created over USB 2.0. Wheeeeeeeeee. FML.

THESE are the times I usually hate Windows a lot. And I do. But it gets MOST of my work done. Except when it does this.

I'm already pissed, so don't go into the comments and just hate on Windows completely. Just a little. The main post is for the main hate. Deal with it. And I know that someone is going to come at me "Ohhhhh, you need FUCKIN LIIIIIIINUUUUUUUXXXXXXXX!' Want to know my response to that?

No.

Oh no AI can destroy hummanity in the future! It is like skynet and such... Bad! It will be the end! FEAR THE AI!

Yeah so i cant sleep now so im writting a rant about that.

What a load of bullshit.

AI is just a bunch of if elses, and im not joking, they might not be binary and some architectures of ML are more complex but in general they are a lot of little neurons that decide that to output depending on the input. Even humans work that way. It is complicated to analyse it yes. But it is not going to end humanity. Why? Because by itself it is useless. Just like human without arms and legs.

But but but... internet.... nukes... robots! Yeah... So maybe DONT FUCKING GIVE IT BLOODY WEAPONS?! Would you wire a fucking random number generator to a bomb? If you cant predict actions of a black box dont give it fucking influence over anything! This is why goverment isnt giving away nukes to everybody!

Also if you think that your skynet will take control of the internet remember how flawless our infrastructure is and how that infrastructure is so fast that it will be able to accomodate terabytes per second or more throughput needed by the AI to operate. If you connect it to the internet using USB 2.0 it wont be able to do anything bloody dangerous because it cant overcome laws of physics... If the connection isnt the issue just imagine the AI struggle to hack every possible server without knowing about those 1 000 000 errors and "features" that those servers were equiped with by their master programmers... We cant make them work propely yet alone modify them to do something sinister!

AI is a tool just like a nuclear power. You can use it safely but if you are a idiot then... No matter what is the technology you are going to fuck shit up.

Making a reactor that can go prompt critical? Giving AI weapons or controls over something important? Making nukes without proper antitamper measures? Building a chemical plant without the means to contain potential chemical leak? Just doing something stupid? Yeah that is the cause of the damage, not the technology itself.

And that is true for everything in life not only AI.

The default USB voltage hould have been specified to 6 instead of 5 volts.

Six (6) volts would allow for longer cables than five (5) volts do, since the spare voltage compensates for the resistance of cables. This is even more crucial for USB hubs. USB hubs are highly dependable upon these days due to laptop vendors dropping the number of USB ports down to two or even one. I am looking at you, Medion.

If several devices are connected to a USB hub, the voltage can quickly drop below 4.5 volts due to the resistance between the USB hub ports and the computer's USB port, causing some devices to restart themselves even if the computer's USB port is not over capacity. If it were over capacity, it would just regulate down its output voltage to prevent overcurrent.

Lithium-ion batteries need at least 4.3 volts arriving at the battery terminals to fully charge, and mobile devices are typically not equipped with a boost converter. Even if they were, they are rather inefficient, meaning they would produce significant heat and waste a power bank's energy. Other USB devices such as flash drives and peripherals might power off below 4.5 volts. However, 6 volts have solid 1.7 volts of margin to 4.3 volts, more than twice the margin of 0.7 volts that 5 volts have. On the way from the power supply to the end device, the voltage has to pass several barriers which weaken it, including the cable, connector endings, and the end device's internals such as the charging controller.

Sure, there are quick charging standards such as by Qualcomm and MediaTek which support elevating voltages to nine (9), twelve (12), and even twenty (20) volts. However, they require support by both the charger and mobile device. If six (6) volts were the default USB voltage, all devices would have been designed to accept this voltage, and longer cables could have been used anywhere. Obviously, all USB devices should be able to run on five volts as well.

Six volts would have been more stable, flexible, and reliable.

Okay, so yesterday was crazy. So crazy, in fact, that I'm not even typing this on my phone. I'm typing it on an LG G4.

So, I took an Uber out to a Sprint store I'd been told did repairs. My phone's vibrator was broken. So, basically I thought just like that R&M episode "20 minutes adventure in and out" - only to find out they'd need to wipe my goddamn phone, and then send it to Texas. I now have to wait 6 days for my phone lmfao.

So, in the meantime, they took an hour to get me this G4 which makes me miss all the finer things in life - I miss my USB-C and not having to give a damn about how I plug it in and I miss my fingerprint reader (I know, I'm a lazy fuck with first-world problems. I don't care to hear about how fucking stupid I am for either of those thoughts, STFU). Also the G4 is prone to hardware failures, so they said they weren't too happy about giving me this, but it's the only one with NFC.

So in the middle of setup, the Sprint store's power went out. FUUUUUUCK. The phone was pretty much at 5% battery and was being slow as hell, so you can just about imagine the irritation me and this guy had when the phone died in the middle of setup.

The next thing is an unrelated story, but I'm sure some of you older guys here will love this. I was at a place called Triangle Park last night. I go there for burgers, but they also have a bar. Sometimes I get sent to the bar and the bartender gets me my food. So last night I went to pick the food up from the bar for takeout.

The bartender must've had an accident and messed something up, so she told me to sit at the bar. I thought it was obvious I was only 19, so I barely sat. I'm literally not old enough to sit at the bar, even though when I was younger my dad and his friends used to let me sit with them because I had a history of saying stupid shit that made his friends laugh. Nonetheless, I sat with my ass hanging off the edge because I knew it was wrong :/

She comes back and asks what type of drink I want. I had to tell her that I was 19. I wasn't gonna sit here and lie because I'm pretty sure she could've lost her job for serving a minor. I exited and waited in the lobby.

But are we at the point where 19-year-olds look like 25-year-olds? I don't want to think about this because it means I'm getting older. That's a lot to take in. Later in the night it was still gnawing at my gut.

Yesterday was one hella day man.

I know "windows 10 bad" rants already have been done enough and are kinda redundant at this point.

But it's so frustrating for me when doing event stuff.

like yesterday during a quieter part I wanted to pull a USB thing. I knew I've turned of system sounds at least two times one this machine last year and sureley it didn't turn them on again, that'd be silly ...
"de dung"
shit!

And today I did some stuff and realized somehow the energy settings are at "balanced".
In the past I had went through every neccessary box to go Full Power, checked every neccessary box, but nOOooOo - lets randomly be balanced again. WTF?

And it's not like shit didn' work already - I remember the times when bluetooth actually was intuitive to use and settings didn't randomly change - is that what they think " progress" means?

Hey guys.
This was my project for today.
Power supply, 5v USB 25A x2; 12V 10A x2; extra power standard cables to power HDDs and such.
Plus a sand paper whatever it's called :p

Ps: Need to know how to power it without the standart power supply, with cables direct to the brush motor pins. Anyone knows? Have arduinos, l293, easy shields, uln2003a... Would one of this work?

Hope you guys like my 🤪 ideas

This is incredibly interesting. How the frikkin-frik did the WiFi and Bluetooth die on my Raspberry Pi 3. Yes, I realize they work in tandem but how does something like this just die after just sitting around and performing light duty tasks for just a few months.

Reinstalled Rasbpain 2 times, nothing. USB WiFi dingle works great.

Not really a rant but I wonder how shit like this happens.

The Pi is in a case away from my cats, in a temperature controlled environment and adorned with the official power adapter.

Things that make you go hmmmmmmm.

TLDR; windows sucks donkey balls

Sometime ago I started to get battery issues on my laptop using windows. Even with 100% charge it would soon display 0% when unplugged.

A few months back I switched to linux on my laptop and on my desk station. And to my surprise, battery issues dissapeared while using linux (manjaro i3). Anybody had that same problem?

Anyway I dual boot win 10 and linux just in case I'd need windows, and this week I noticed my root parition didn't have any space left.

For the next few hours I'm in a car so I thought hey great time to reinstall linux with a bigger root partition. I already had reinstalled windows, and with all the bloat removed, I could shrink my windows partition to make more space for linux.

Now all I need to do is prepare a usb stick with the manjaro iso. I could do that in linux, but since reinstalling windows killed my grub bootloader I couldn't boot up manjaro.

Right, so in windows I go and want to create this bootable EFI usb stick from the manjaro iso. Now the battery issue kicks in again, stating 0%. But with luck, the usb creation finished without my machine dying. Now I just need to restart my laptop and boot from the usb and .... Crap. my Laptop doesn't boot up anymore
-_-

Now i need to wait for a plug to be able to power it up again. Once I boot from the usb I'm sure I could use the laptop some more hours until the battery is actually dead. Fuck windows

Resently I was messing around with USB extender cables that I had lying around. And I made this.

And I got it to ba able to go pretty far but then I realized that I could spider man my external battery from outlet to outlet.

I am calling it spideemanning.

MacBook Usb power is 500mA if I plug an Android and 2000mA for iphone... I hate it, anyone knows if this can be controlled? The usb ampers? Or is another Apple "feature"

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 spent two hours trying to find out why the wifi dongle on a new device we're building doesn't start (it's detected by linux and all so technically everything works) tried the scripts we use on a raspberry pi they work perfectly. I just noticed someone (most likely the cleaning lady) unplugged power or the usb hub I'm using.

Nice

Alot of hacks around here!
An extract of some of those:
-Couldn't time the shutter right when photographing lightning. Used my oscilloscope to measure its electrical influence and anytime a peak is detected, it actuates the shutter.
-Using a lock as a heatsink for a overheating display driver ic.
-Hacking two USB ports together to get more power.
-Display module was too tall with header pins. Moved its back components to the main board and soldered the module flat onto it by flowing solder down its connecting holes.
-Not me but still interesting: Back on ye olde times when paid tv contained a disruptive H or VSYNC signal only their paid tv box could filter, my electronics prof. analyzed it and built the required comb filter on his own. Even sold some on the black market.

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)

it just dawned on me I could modify the fs on my arch installation usb.

i could include the passphrase for the wifi I'll be using, and a script that runs:
* wpa_supplicant and dhclient
* setfont for a bigger font (so i can see shit)
* most of the install commands that i rarely customize
* installs all my dotfiles on the target partition

i am trying out different configs for my laptop that has shitty optimus (like which one draws more power using powertop).

so i would appreciate testing these things from scratch, and automating the install helps with that

Going to sound sarcastic but for once I'm not...

It's hard to really appreciate how set and forget Linux distro's actually are, I have no internet at the moment and have to use a USB wi-fi dongle, windows rerquires I install a driver yet and so does a USB-C cable (Don't ask why a fucking cable needs a driver to transmit power but hey), I connect both up to my Linux install (Elementary OS) and boom, straight out the box they both work perfectly .-.

When you buy a HAMA USB power adapter and it fails after one week... Raspi down.

Only today have I realised that laptops will run slower if the power supply is not sufficient. If batt or the charger is too weak. And sometimes a charger slows the laptop the fuck down. Or even freezes it (for some reason) to halt.

I need a more powerful USB-C charger

I always thought laptops and charge controllers/batteries were tuned to ensure the power the device needs and disconnect the charging or leak energy from the battery if a charger is too weak. I stand corrected

Back in 2005, I had quite a few bits of music I was working on (just as a hobby). A lot of these had not been finished, but I'd sent excerpts in medium-quality MP3 format to a friend. I had an external backup drive - a regular hard drive in an USB enclosure. After a while, this drive started making unpleasant whining sounds so I sent it off for replacement.

During that time I made the foolish decision to try and plug a floppy drive in while the PC was powered on. Something touched the bottom of the hard drive and the power went off. I powered it back on again and heard a fizzing sound, there were some flashes from the hard drive and a burning smell. Yep, the disk was dead - and my backup drive was gone.

I'm still not entirely sure what happened, my best guess is that I had an exposed piece of wire from one of my hacky case mods (I had a thing for blue LEDs) which touched the circuitry of the hard drive. Almost every project, piece of software I'd created, every photo I'd taken, and most unfinished music I'd made up until that point - gone. I was pretty devastated about it. I only had a handful of things survived which I'd burned onto CD previously.

I managed to get some excerpts back from my friend, and re-created my favourite pieces of music based on those. I've moved on to other projects and write much better code now, so mostly I am no longer bothered. I do wish I could re-listen to some of the music I had made back then though.

Needless to say, I no longer fiddle around with the innards of my computers while they are on, store everything on mirrored drives and also ensure I always have a backup somewhere (and am working on remote backups and having several days of backups...)

I never want that to happen again

Tried to boot ReactOS on real hardware.

ALL the driver issues, and no way to fix them (USB had drivers assigned but only had power, not even my mouse worked.)

God I wish ReactOS was laughed at less. There's so much here that could grow into a full Windows replacement, but people are too busy laughing to help.

It's like comparing Windows 2.x to Windows 7 or 10. There's something there, it's just not progressed far enough to get up to where it could be. (Not literally ofc, metaphorically)

Need advice. I run all my development on a desktop that I have been happy with for years. Now it keep crashing (probably due to forti client which I need for a contract).

I am frozen in looking for a replacement. Will a laptop give me the freedom I want but not enough power and USB options? Will I be wasting 1000k buying one?

I do all sorts of dev: visual studio, eclipse, PHP, c#, Apache, IIS, SQL server, MySQL.

I pretty much have to be prepared for anything.

But I keep thinking a laptop will give me this mobility that I may never use.

I probably should stick with a desktop.

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?

Has anyone else found that not all USB C inputs are the same? You can't just buy an cable and expect it to plug into any socket.

1. I replaced the cable for a power pack, but the new one didn't fit my OP6 socket well, no clicking and have to push it in very hard to get it to charge, and still eat to fall out
2. The pixel 2 cable fits it nicely and all cables are ready to plugin and work
3. I tried charging my new Pixel 4a with ur though but very hard to plug in. Had to install the charger and cable that came with.
4. Amazon Fire takes all of them nicely and send all the others can use the cable that came with it too

I‘ve now my first smart home device. It is only a power outlet, but the story behind it is a bit special.
Because Apple trapped me in there ecosystem I wanted to have a HomeKit compatible outlet. The problem with that: Either to expensive or to big. So my ne mission: Connect a non HomeKit device to HomeKit, but without a too expensive proprietary gateway/bridge.
After a bit of googling I found a software called "Homebridge", build to run on a Raspberry Pi. Fortunately I had one old RasbPi 1 B. So I installed a new Raspbian and installed Homebridge. I forgot how slow it was.
Then I bought a cheap (but good) ZigBee outlet and a ZigBee USB Dongle. With a plugin for Homebridge it was very easy to connect the ZigBee Dongle.
Then I tried to connect the outlet, but the log said "Unrecognized device". After a bit of research I found out that the outlet is not supported by the homebridge-zigbee plugin. As a software engineer I tried to find a solution for it, so I reverse engineered the device recognition (very easy because Homebridge is a node application). After a while I managed to add the configuration for the outlet to the plugin.
And see, it became light.

#eletrónics, #power suply
Hey guys, I have a question about power.
I converted a 400w power suply into a power suply for my projects.
With more than 10amps per wire can I use the 5 volts to power stuff like my phone or Will it burn?
Also it gives 5.3v is that a problem?

Just found out that I can share power using USB OTG

!dev (kinda)

Warning: Might contain (be) stupid rambling.

So I got my new toy and want to play around with it. Just in case I have to return it I first want to make a full disk backup, so I try to boot clonezilla. I press the power button and mash F2, F8, F9 - and it boots straight into the windows setup. Nope, not what I wanted. Try again. And again. Eventually I look it up and apparently I have to hammer the ESC key to get where I want to. Alright, now it works. Boot from USB. Failed. Try again. Failed. Check the BIOS, disable secure boot, reboot. I need to type 4 digits to confirm disabling secure boot. Alright. Reboot, try again, failed. Secure boot is on again. Wtf? After some more infuriating tries I see that NumLock is disabled. AAAARGH. BIOS: Enable NumLock on boot, disable secure boot, enable legacy boot. Input the 4 digits - works! Try to boot from USB: Failed! Grab another USB stick, did the clonezilla image, try again: Finally! It! Works!

Format disk, install Qubes OS. Success!
