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.22 -
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.6 -

This is what I've been putting up with on my personal machine for months.
tl;dr: Suggestions for a wlan card/adapter for Debian9? My current RealTek wnic is barely functional, and my replacement (a TPLink... something) is completely incompatible.
I don't need anything super fancy, though I would ofc love support for AC/AD if at all possible.
I don't care (too much) about price, since I'm only going to buy one and very likely won't replace it for years.
------
I'm running Debian9 and have a have a RealTek card. Even when it's not arbitrarily dropping packets like in the screenie, it randomly caches them for up to 90 seconds and dumps them hilariously out of order. I can't play games like that. I can barely even browse devRant. Steam goes offline about once every 30 seconds, and therefore spams all of my friends with online/offline notifications. Streaming "works" on good days. Git works fine, however, so most days I don't notice the connection issues.
And yes, I'm using a community-patched driver (rtl8188ce) that's supposed to fix some of RealTek's more major screwups and increase the transmit power by ~20x. The driver helps, but only a little.
I've done some reasearch on wlan linux support, but haven't found anything very reassuring. Mostly just forum posts saying things like "Intel cards usually work fine!" I don't want to gamble. I just want to buy a card that will work and be done with it. :(
Suggestions? Insight?10 -
It says "There was no battery found."
This laptop was not connected to a power adapter, but Windows also said that there is no battery. Did I missed the update where Microsoft implemented magic wireless energy?7 -
This freaking laptop.
The WiFi randomly stops working -- and by that, I mean the hardware is no longer detectable, let alone functional. It simply disappears on boot, even from dmesg.
The same happens with audio and bluetooth: on some boots they simply do not exist.
The power usage is also ridiculous: the battery dies in about two hours, and it gets soo hot. Toasty wrists unless I use my tiny bluetooth keyboard ☹ So I need to fiddle with powertop a bit more.
nVidia drivers are also a bloody pain, and having two graphics cards this is even more difficult to set up. I still haven't managed. (nvidia-driver, bumblebee, optimus, official driver messes, manual xorg configs, ...). So I have a beautiful 4k built-in display running at 4-18 fps, and a non-functional 4k external. That's fine for now, but >.>; frustrating.
In better news! I just managed to get the sound to work by backporting the new 4.19 kernel (yay!) -- I have never been so happy to hear an ad. but fixing the sound killed my bluetooth. (The `bluetooth` utility reports the adapter is present, but nothing else can seem to see it 🙄) So now I'm going to have burning hot wrists all day and want to cry because terrible sweaty awfulness.
Just. It's frustrating.
It's fast, though.
and ever so pretty.28 -
Working on my Lenovo x1 carbon. Akku warning "less then 6%" appears. No problem, I will connect the cable just after I finished this function... "Will shutdown in a view moments" message appears. Ok, I connect the cable. Nothing happens. Maybe power adapter is broken or something more worst. Panic. Try to commit and push as fast as I can (around 2000 LOC from today, made big changes on my project today). While pushing to github laptop powers off. Fuck. Check github on smartphone to see if commits had been pushed. No. I do not have a power adapter for replacement. FML.4

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".12 -
Who decided it was a good idea to use this as a desktop PC's adapter?
Yeah lets change the kind of cable you need to power on our pc to one that apperently nobody sells. Profits guarenteed.4 -
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.14 -

All of a sudden the Macbook Pro power adapter was broken yesterday. Guess how much does it cost just to replace it?
Fuck you Apple. If you're gonna overprice, it make it durable and good quality dammit.9 -
Fuck..I lent someone my laptop and they returned it with a different power adapter and most of the keyboard keys don't respond when I press them. Now I can't code or do anything coz all I ever do is code, really.4

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...2 -
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.10 -
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. -
The contractor/developer sitting next to me asked for a power adapter for the MacBook the company issued him (it's an older MacBook that currently connects to his monitor with one of those 2-in-1 power and display port cables).
They told him it was not company policy to provide power adapters to contractors.
They also wouldn't give him a license for a Windows VM for some Windows specific stuff he needed to work on for an outside vendor, stating it was a "security risk"
They've also talked about taking Linux off my laptop (which I run natively outside a VM cause fuck MacOS).
I hate our IT department. They're the least competent and least helpful bunch I've ever met. -
So Igot that Samsung DeX thing a while ago. So far, it was just a nice gadget to have at hand, but I didn't get to use it properly since my laptop was always the better option sort of.
Now.
My power adapter for the laptop died last friday. I have a second one at home, but of course, I pack the wrong one for work.
Ended up working the entire day on the DeX. Thankfully, I just needed to do some web and office based stuff, and all the necessary documents are online anyway.
So that thing just saved my butt today, which is nice. Took a while to get used to, but it does it's job quite nicely.
To be honest: Iam suprised it works the way it does. Oh what a time to be alive...
Now the question is...
Can I get Ubuntu on here somehow? I did find a Tmux? shell and was able to download some ubuntu onto it, but it had gpg issues.
Anyone got more references? Ubuntu on Android 8.13 -
Fucking windows updates...
Went to do a job on a tank in 18 deg F Weather with snow on the ground. One guy brought an ice fishing tent (very nice). This is next to petroleum tank. We got guys on top of tank waiting for me to get data using a Windows 10 lappy.
Lappy comes up and tries to get into bios to do a firmware update. WTF! I reboot and it does it again! Go to look for power adapter as it wont do update without power. Not in bag. It has to have power to do update.
So I drive back to shop (with guys waiting on top of tank) which is 5 miles away. I am pissed. Its snowing and I have to drive slow. I find that adapter. I get back to the tank and plug it in. The AC source (battery based) starts alarming as the lappy takes too much power. Fuck! But somehow it boots Windows without doing firmware update. Fuck you Windows!
I get my job done, but don't fucking trust windows at all. Had this been a field tech he would be pissing his pants. Useless shitty software you have zero control over. Now considering changing their OS to Linux for field work. I am rewriting their software anyway with something can run Windows or Linux.4 -
Waiting for the call I scheduled with Apple Support regarding my faulty power adapter. What is your experience with Apple Support? Any pointers you wanna give?2
