Long rant ahead.. 5k characters pretty much completely used. So feel free to have another cup of coffee and have a seat 🙂

So.. a while back this flash drive was stolen from me, right. Well it turns out that other than me, the other guy in that incident also got to the police 😃

Now, let me explain the smiley face. At the time of the incident I was completely at fault. I had no real reason to throw a punch at this guy and my only "excuse" would be that I was drunk as fuck - I've never drank so much as I did that day. Needless to say, not a very good excuse and I don't treat it as such.

But that guy and whoever else it was that he was with, that was the guy (or at least part of the group that did) that stole that flash drive from me.
Context: https://devrant.com/rants/2049733 and https://devrant.com/rants/2088970

So that's great! I thought that I'd lost this flash drive and most importantly the data on it forever. But just this Friday evening as I was meeting with my friend to buy some illicit electronics (high voltage, low frequency arc generators if you catch my drift), a policeman came along and told me about that other guy filing a report as well, with apparently much of the blame now lying on his side due to him having punched me right into the hospital.

So I told the cop, well most of the blame is on me really, I shouldn't have started that fight to begin with, and for that matter not have drunk that much, yada yada yada.. anyway he walked away (good grief, as I was having that friend on visit to purchase those electronics at that exact time!) and he said that this case could just be classified then. Maybe just come along next week to the police office to file a proper explanation but maybe even that won't be needed.

So yeah, great. But for me there's more in it of course - that other guy knows more about that flash drive and the data on it that I care about. So I figured, let's go to the police office and arrange an appointment with this guy. And I got thinking about the technicalities for if I see that drive back and want to recover its data.

So I've got 2 phones, 1 rooted but reliant on the other one that's unrooted for a data connection to my home (because Android Q, and no bootable TWRP available for it yet). And theoretically a laptop that I can put Arch on it no problem but its display backlight is cooked. So if I want to bring that one I'd have to rely on a display from them. Good luck getting that done. No option. And then there's a flash drive that I can bake up with a portable Arch install that I can sideload from one of their machines but on that.. even more so - good luck getting that done. So my phones are my only option.

Just to be clear, the technical challenge is to read that flash drive and get as much data off of it as possible. The drive is 32GB large and has about 16GB used. So I'll need at least that much on whatever I decide to store a copy on, assuming unchanged contents (unlikely). My Nexus 6P with a VPN profile to connect to my home network has 32GB of storage. So theoretically I could use dd and pipe it to gzip to compress the zeroes. That'd give me a resulting file that's close to the actual usage on the flash drive in size. But just in case.. my OnePlus 6T has 256GB of storage but it's got no root access.. so I don't have block access to an attached flash drive from it. Worst case I'd have to open a WiFi hotspot to it and get an sshd going for the Nexus to connect to.

And there we have it! A large storage device, no root access, that nonetheless can make use of something else that doesn't have the storage but satisfies the other requirements.

And then we have things like parted to read out the partition table (and if unchanged, cryptsetup to read out LUKS). Now, I don't know if Termux has these and frankly I don't care. What I need for that is a chroot. But I can't just install Arch x86_64 on a flash drive and plug it into my phone. Linux Deploy to the rescue! 😁
It can make chrooted installations of common distributions on arm64, and it comes extremely close to actual Linux. With some Linux magic I could make that able to read the block device from Android and do all the required sorcery with it. Just a USB-C to 3x USB-A hub required (which I have), with the target flash drive and one to store my chroot on, connected to my Nexus. And fixed!

Let's see if I can get that flash drive back!

P.S.: if you're into electronics and worried about getting stuff like this stolen, customize it. I happen to know one particular property of that flash drive that I can use for verification, although it wasn't explicitly customized. But for instance in that flash drive there was a decorative LED. Those are current limited by a resistor. Factory default can be say 200 ohm - replace it with one with a higher value. That way you can without any doubt verify it to be yours. Along with other extra security additions, this is one of the things I'll be adding to my "keychain v2".

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".

Proxmox team, go fuck yourselves.

Now I'm sure that I'll receive a lot of flack for this, but hear me out.

I've tried Proxmox and was quite pleased with its web UI. But I hate how much it locks me into their own little ecosystem.

I want to use btrfs on my drives. Why is this impossible, yet the hack that is ZoL is your obvious alternative? An alternative wherein I can't even compile and run my own kernel, because then ZoL suddenly fails? And don't you tell me to compile your stock config, when it's well over 15GB large in your source tree.

Proxmox is literally the MacOS of Linux distributions. Which was even more so made clear by me being called an idiot by possibly wanting to run Same on the PVE host. Because why on Earth would sysadmins want to?! Why on Earth would sysadmins be competent for wanting to?!!

You know what? I'll just convert those Proxmox servers to Arch and say fuck you to all the bells and whistles that's Proxmox' web UI. Because at least Arch allows me to make my own fucking choices, limited only by what's supported by the Linux operating system.

Perhaps Proxmox will consider btrfs stable in 2021. Because you know, despite it being stable today in 2018, Debian and Proxmox alike live 3 years in the past, i.e. 2015. I hate the Debian ecosystem because of that, but boy do I hate Proxmox even more so. Bloody fucking piece of shit it is!!! 😡

Linux experts, please read if you have time

Seeing all the posts ranting about Ubuntu, I'm starting to wondering : I have a laptop on Ubuntu that I set for my courses at school, I took Ubuntu because I could try at school with VMs, liked it and because between this and Linux Mint, I wasn't aware of all those distributions.

So my reflexion is : Since I've started my internship, which would be the final semester (I'm in last year of studying), I use this computer mostly for personal coding projects, which aren't ambitious and I sometimes use my Windows too, so my computer is a kind of switch-not-so-often.
Should I keep it to Ubuntu or should I try to install something else ?

I've heard of Solus, which got my curiosity, and Arch Linux, but this one is not want I think I need. But seeing all those distributions here made me confuse, I dunno if I should upgrade something that's a kind of placeholder for coding and do stuff when the Windows (which is my main laptop) is busy doing things.

Have any suggestions ?

I'm learning Kotlin while trying out Android Things and that sparked my interest in learning more about Java platform again. I tripped upon the news that Oracle had change their commercial plans for the platform by going with the rolling release model and limiting LTS releases for paying customers.

Java SE 8 was one of those former LTS releases that was on my computer, leaving me vulnerable, despite that version still being the most compatible with many applications, and that's been on my computer well passed the date they cut off public support. And I'm, like, "WTF!?"

Luckily this is when open source shines at it's brightest. Both the home brew and corporations, such as Amazon and IBM, alike - mostly the latter - both agreed to create their own LTS releases using the OpenJDK code and all disturbing to the public FOR FREE with no strings attached and the sources opened. I'm sure Richard Stallman is smiling with glee.

It isn't a total finger towards Oracle. Java SE is based on OpenJDK with no difference between the two anymore aside from loss of LTS support from the public - that's it. So Oracle still benefits despite the retaliation. Probably?

Did Oracle learn nothing from OpenOffice? If the point was to get users to pay for security then they've failed in the long run because Java is open source. People have used that fact to create their own free distributions that bypass their paywall, making the need to go through Oracle pointless. And I'm glad. Open source aside, security is a big issue these days and the last thing people need is yet another thing to subscribe too.
