Not sure if "good" is the right word, but at least cool.

Torrenting, high speed mobile data modem (especially with manual selection of frequency bands on MediaTek), local OpenSpeedTest server (available as app), WiFi analyzer (most used channels), VNC client, the slowest x86 emulation in Qemu-based Limbo PC emulator, SDR receiver software (SDR++, SDRAngel, Welle.io, dump1090, SatDump), RTL-TCP server, SSTV decoder and encoder, HTTP proxy server, Kiwix server, NGINX web server/proxy, Navidrome server, Cloudflare proxy client, SSH server, VNC server (only for Termux's desktop), satellite tracker, Mifare Magic NFC card programmer (MCT), audio spectrum analyzer, serial terminal.

I wanted to attach screenshots, but realized it's way too much stuff.

If you are also white, not only will you be granted entry, you'll also immediately get citizenship.

I am sure there would still be someone who'd want to play online chess with you.

 

TTL

The default TTL for Android is 64. Default for Linux is 64. Default for Windows is 128.

When a packet passes through the router, its TTL is decreased by 1. So a packet from your phone will have TTL of 64, while one from device on hotspot will get decremented to 63 when passing your phone, acting as a router.

Unless it starts with 65, then gets decremented to 64, the same as with your phone directly.

On Linux you can temporarily change this with

sysctl net.ipv4.ip_default_ttl=65

as root.

If the carrier just checks the TTL, congrats.

I haven't played around with IPv6 hop limit.

HTTP proxy

If that doesn't work, you can try to proxy traffic through the phone. I like to use Tinyproxy in Termux.
The config is pretty simple, and also supports (unencrypted) authentication with username and password.

Another option is an all in one app like TetherFi. It creates WiFi Direct group (without direct internet access), and has a built-in HTTP proxy.

Both ways allow also using your phone's VPN.

The HTTP proxy can be easily configured in Firefox, for example. For Android, there is a pretty cool app called NekoBox which is a proxy client for many different protocols. It uses the VPN interface to pass everything through the proxy, thus giving you full device connectivity on the other device.

TinyProxy: https://tinyproxy.github.io/ (can simply be apt installed in Termux)

Termux: https://f-droid.org/en/packages/com.termux/ (terminal emulator for Android)

Slovakia

Notify my employer that I won't show up, go to doctor and wait in the waiting room. When the nurse shows up, give her the insurance card and wait for your turn. They'll check you, and if it's nothing special (requiring a specialist), you'll probably get prescription for some meds to pick up.
Then you get those in a pharmacy. Either it's electronic, or if the system is once again broken, you hand them the Rx paper that the Dr. gives you in that case. And then you figure out what you're about to pay. A lot of things will be fully covered by insurance, but potentially you'll have to copay. There's also a chance the Dr. tells you to get something that isn't covered, like some specific eyedrops, cough meds, probiotics (if you have antibiotics for example), etc.

The pharmacist may recommend a cheaper alternative, will likely tell you recommended dosage, tell you that once again this specific Dr. prescribed something that hasn't been manufactured for the past 30 years, and in the rare case, tell you the prescription seems dangerous and to contact the Dr.
And also decrypt any handwriting/encoding.

wait until it’s below 20%

Not quite the same. No reason to discharge it before topping it up. If you do want to top up from 70% to 80&, that's not a problem for the battery, just perhaps the charging connector if you do that a lot.

I had luck with VNC, although it's still worse than RDP. There's also some RDP implementations on Linux that are apparently better, but VNC works well enough for me.
But there's no sound, I don't know if RDP has that. I've used VLC for sound forwarding. I also tried PulseAudio TCP module, but that didn't quite work. With VLC I can do lossy compression.

What I wish would work better is X11 forwarding. That could be so awesome, just having the remote windows local-like. But from what I can find, in the past, programs used X11's drawing features which would save a lot of bandwidth, while now they just draw pixel by pixel.

To give you some idea, I've tried it on LAN with gigabit ethernet, ping below 1ms. It would saturate the port and still be kinda slow.

I also found it OK-ish, at least after my usual disabling of BITS and SuperFetch (SysMain now, I think), and disabling auto-updates, I think in gpedit.msc, and using the provided BypassNRO.cmd to create local account.

Alright, maybe not that OK, but after the initial setup it ran fine even on officially unsupported computer made in 2007. Just had to modify the installer by merging W11 image into W10 installer.

Anyway, the Windows store or whatever isn't that used, and I got tired of updating every random program coming from .exe files. But similarly I don't like the large hops in versions like Windows 10 -> 11, or similarly with Linux Mint, so I went with Arch.

Anyway, I'll be a smaller minority. I most liked Windows 8.1. It was really well optimized.

But the "No refuge could save the hireling and slave, From the terror of flight, or the gloom of the grave" gets louder.

~~^test^~~

Eh.

I like them. It spins, it makes a sound when being used, it looks cool, I have to be a bit more gentle with it.

[–] user224@lemmy.sdf.org 2 points 3 days ago

I think this could rather be related to power saving if the screen is locked.

I prefer to use a dedicated internet radio app. VLC also works if you obtain the direct stream (check online or play around with element inspector).

 

I worked the night in Budapest, and stayed longer. My father tried to call me thrice, twice of which did actually get to me (loss of signal), but I didn't pick it up. Apparently he also sent me a few messages, but I didn't retrieve those*.

When I got home, of course that was the first thing I heard of, along with the stupidest reason yet.
(approximate from memory) "Why don't you pick up phone or reply to messages? We were really worried about you. There's pride over there right now desbite Orbán banning it. It's full of LGBT perverts, anything could have happened to you."

And the first time I told them I'll work the night (I don't know if I can use "nightshift" when it isn't shift work ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯), they were very strong on disagreeing with that, stating that if I'll be outside at night, I could "get raped by a homosexual".

* Calls are forwarded to my current number, but that's not an option for SMS. I updated my current number where relevant, leaving out just my family, which is basically just my parents and aunts spamming me with christian stuff or telling me to tell my mom to call them (why?). Retrieving SMS thus refers to switching the SIM card for like 2 minutes (switched to eSIM for convenience).

 
 

Just because I can.
But it also proves 2G is still at least somewhat usable.

I would just switch my phone to 2G only and then continue the download in Termux using wget because that's most reliable way to download files.
I let it run overnight, then stop it when I needed my phone during the day, then let it run again at night when not needed anymore.

However, 2G is quite inefficient, so this actually drains the battery a lot.

I wonder if the carrier just sees a weird spike in 2G data usage.

Anyway, calculation time. Wikipedia Kiwix ZIM file is approximately 110GB. 109,886,078,976B to be precise. With average speed of say 21KB/s, it would take around 2 months to download the whole English Wikipedia with low res pictures over 2G EDGE.

But also EDGE is quite better than original GSM Data (CSD), which offered breathtaking 9600bps.

 

Better photo available here: https://english.nv.ua/russian-war/ukraine-begins-treating-soldier-scarred-with-glory-to-russia-phrase-from-russian-captivity-50522497.html

The words, written in Russian, were branded into the right side of the body alongside the letter "Z," a symbol of the full-scale invasion that many Ukrainians and critics of the war liken to the Nazi swastika.

According to the United Nations, more than 95% of freed Ukrainian POWs have said they were tortured during their captivity. Survivors have recounted harrowing treatment, including being brutally beaten, electrocuted, and forced to endure painful stress positions.
Many have faced mock executions, threats of rape or death, and were denied basic medical care. Some were left without food, locked in isolation for weeks, or permanently marked with burns or scars.

For Turkevych and his team, seeing the scars left by Russian captivity on Ukrainian POWs has become a routine part of their work.

[...] Turkevych and his team have treated several released defenders bearing swastika-shaped scars, some even on their foreheads [...]

 

Usually they're tolerable, just annoying.

The screenshot is from one I found installed outside Lidl (supermarket) now, above the entrance. Probably loud enough to "cover" the entire parking lot. Loud enough to get painful after a few seconds. Sweeping between 15.5kHz to 18.7kHz. For comparison, a CRT TV is around 15.7kHz.

I wonder if not caring about loudness of these higher frequencies contributes to hearing damage among people.

Lower frequency, but also awfully loud buzzers can be found in trains near doors, working as a warning when the doors are closing. Thankfully, this probably annoyed some of the staff enough for them to start taping these over.
But those are loud enough to sound distorted.

Anyway, I just hid behind a corner where I couldn't hear it that much while waiting for the manager to call us in.

 

Preface

My bank blocked my card due to a "high risk transaction"... again. This time they told me unblocking isn't possible, and issued me a free replacement.

And as the title says, as a kid I wanted to try putting a cut-out bank card chip into a phone. Yes, I grew up in 2FF era.

The... thing

I also stripped the front foil because I was curious what's under it. Nothing. The card is just flimsy without it, and the chip contacts raise above the card.

The abomination in comparison to real SIM cards:
The thing next to T-Mobile and GiffGaff SIMs

I have contactless and magnetic payments blocked. Only chip + PIN, thus the wear.

Attempts
  1. Samsung GT-S5830i (Android 2.3.6) - "Insert SIM"
  2. D-LINK DWM-222:
 -----------------------------
  Status   |             state: failed
           |     failed reason: sim-missing
           |       power state: on
  -----------------------------
  1. Alcatel 1066G:
    This is the only device with observable difference.
    Without SIM:
    Display saying "Insert SIM"
    With the... thing:
    Abomination inserted Display saying "Searching network"

At least it detects something. Contact and SMS storage says "SIM not initialized"
The "Searching network" eventually fails (what a surprise), and switches to "Insert SIM" after a few minutes.

About the blocking (unrelated to post)

Bureaucracy

Apart from what's in the preface, the documents I signed still mention the standard 10 EUR charge. I asked to see what I am signing this time rather than just issuing the signature on their tablet and trusting the employee.
This time around, there is "fee will be individually assessed and charged" as well, and if I do get charged, I was told to dispute it at the bank.

Last time when giving me a card at the bank they just charged me anyway. Interestingly, that time the official reason was given as "card not delivered after 2 months". If that were indeed true, why should that be my problem?

That was when I just opened the account. They told me that I could get the card immediately ("free") rather than wait for it to arrive by mail.

Blocking process

Message from automated system approx. 12 hours before card blocking:

Plus, the payment worked on second attempt.

OH, FUN FACT: I didn't even use the physical card, but a digital single-use card generated in the bank app.

So, they blocked physical card, after suspicious payment made using digital card, and even if that made sense, they waited 12 hours and let my second attempt through.

The other 2 times the blocking happened after donating to archive.org

Ironically, it worked with one of Mullvad VPN servers.

 

Previously I just played around with a faulty DVD burner to make some lame stripes: https://lemmy.sdf.org/post/28673131

Used software

https://github.com/arduinocelentano/cdimage
It creates an audio track with carefully placed data to create visible images with pits and lands.
Quite crazy when you realize that this is a 5.38km long spiral

So... yeah... did I say I don't know to use GIMP? Well, how about some LibreOffice tomfoolery?

The presets needed a bit of fine-tuning since it isn't exactly the same Verbatim disc, but it was close enough already.

Other attempts

1st attempt with default values


Thankfully it was pretty close, and I only had to change 1st track length. Although it still doesn't look quite perfect. I am not sure what "Track delta" could be, and honestly not even the 1st track. Maybe the former refers to exact track pitch? Dunno.

A regular photo

Looks good. The photo source is X (formerly known as Twitter), so that sucks source-wise.
But an alternative is here: https://railcolornews.com/2023/11/20/cz-finally-bolt-the-railway-dog-reveals-locomotive-name-after-himself/

As the URL hints, this is a photo from Czech Railways' introduction of Siemens Vectron locomotive named "Boltík" after Bolt's fursona.
Unfortunately, it's missing the name after being repainted, I don't know what's up with that, but that's also off-topic.

Sound sample

So, the images are cool, and they are quite crisp (if I don't use LibreOffice as image editor xD), but how does it sound?

You see, it's just an audio track.

Here you go: https://files.catbox.moe/kjhumj.flac

And for Lemmy WebUI users, an embed should work too:

Maybe. It's FLAC, I've used it with MP3 successfully, will depend on browser too.

Most apps try to display this audio as picture, but there is no picture. Well, I mean, technically a few meters of it.

 

Original post: https://lemmy.sdf.org/post/34817172

Previous post summary: I wanted to activate foreign (Czech) eSIM, it didn't work, so I traveled to Czech Republic (neighboring country), it didn't work there either

So now I just tried it again (in home country). I just got the idea that, perhaps, I can try different LPA software. Can't lose anything. I downloaded the profile, enabled it, AND IT FUCKING WORKS.

But OK, I tried the previous software with the second SIM. It... worked too?

To be fair, I still had the alternative installed, so maybe it did something in the background. (Like in terms of profile download notification.) I am not going to try a 3rd SIM.

The software

So, at first I tried EasyEUICC (https://gitea.angry.im/PeterCxy/OpenEUICC), or rather the rebranded JMP variant since that's the same thing but also available on F-Droid.

Now I tried NekokoLPA (https://github.com/iebb/NekokoLPA) and that worked, but so did EasyEUICC so no idea if it is related.

I originally chose EasyEUICC because I like the UI more, and also Nekoko says "super unstable, use at your own risk"

AAAAaaah...
