tl;dr:
The Debian 10 live disc and installer say: Heavens me, just look at the time! I’m late for my <segmentation fault
—————
tl:
The Debian 10 live cd and its new “calamares” installer are both complete crap. I’ve never had any issues with installing Debian prior to this, save with getting WiFi to work (as expected). But this version? Ugh. Here are the things I’ve run into:
Unknown root password; easy enough to get around as there is no user password; still annoying after the 10th time.
Also, the login screen doesn’t work off-disc because it won’t accept a blank password, so don’t idle or you’ll get locked out.
The lock screen is overzealous and hard-locks the computer after awhile; not even the magic kernel keys work!
The live disc doesn’t have many standard utilities, or a graphical partition editor. Thankfully I’m comfortable with fdisk.
The graphical installer (calamares) randomly segfaults, even from innocuous things like clicking [change partition] when you don’t have a partition selected. Derp.
It also randomly segfaults while writing partitions to disk — usually on the second partition.
It strangely seems less likely to segfault if the partitions are already there, even if it needs to “reformat” (recreate) them.
It also defaults to using MBR instead of GPT for the partition table, despite the tooltip telling you that MBR is deprecated and limited, and that GPT is recommended for new systems. You cannot change this without doing the partitions manually.
If you do the partitions manually and it can’t figure out where to install things, it just crashes. This is great because you can’t tell it where to install things, and specifying mount points like /boot, /, and /home don’t seem to be enough.
It also tries installing 32bit grub instead of 64bit, causing the grub installer to fail.
If you tell it to install grub on /boot, it complains when that partition isn’t encrypted — fair — but if you tell it to encrypt /boot like it wants you to, it then tries installing grub on the encrypted partition it just created, apparently without decrypting it, so that obviously fails — specific error: cannot read file system.
On the rare chance that everything else goes correctly, the install process can still segfault.
The log does include entries for errors, but doesn’t include an error message. Literally: “ERROR: Installation failed:” and the log ends. Helpful!
If the installer doesn’t segfault and the install process manages to complete, the resulting install might not even boot, even when installed without any drive encryption. Why? My guess is it never bothered to install Grub, or put it in the wrong place, or didn’t mark it as bootable, or who knows what.
Even when using the live disc that includes non-free firmware (including Ath9k) it still cannot detect my wlan card (that uses Ath9k).
I’ve attempted to install thirty plus times now, and only managed to get a working install once — where I neglected to include the Ath9k firmware.
I’m now trying the cli-only installer option instead of the live session; it seems to behave at least. I’m just terrified that the resulting install will be just as unstable as the live session.
All of this to copy the contents of my encrypted disks over so I can use them on a different system. =/
I haven’t decided which I’m going with next, but likely Arch, Void, or Gentoo. I’d go with Qubes if I had more time to experiment.
But in all seriousness, the Debian devs need some serious help. I would be embarrassed if I released this quality of hot garbage.

In my day off I was eager to try overclocking in my pc and this is how it went:
- Fucked up overclocking parameters for cpu and ram speed.
- BIOS is broken, had to take out gpu to do a reset taking out the bios battery.
- BIOS is up again, default values loaded, bla bla
- Did not try to fuck off anymoar with overclocking, just kept playing star wars and went to sleep safe and sound like a baby.
- Gotta work now. docker does not start, closes itself after tried to start, docker panic, I panic, tried to uninstall, tried to update. nothing works
- Then I remember bios default values leaves virtualization off. enables it again, docker still not working. I panic again, restarted pc like 10 times between disabling/enabling hyper-v in windows.
- Docker dies. not gonna change my overclock options again. silly me 🤦♂️9 -
So, funny story with a bit of self promotion at the end.
I was recently checking out some apps on playstore and found that my first ever , "launched just to experiment" app (released 1.5 years ago) has received more than 5k downloads . I was very happy about that so posted a small message on LinkedIn .
Now , my LinkedIn profile consists of 98% people who are totally strangers and never met me ( is it just me or do you also get a lot of stranger connect requests there?). So my usual post rarely ever goes beyond 5 or 6 likes.
Bit idk how there too my post got 35+ likes and now i was on cloud9.
So i finally decided to kick my ass and release some update to that app ( it had around 70% pity comments like "nice first app,but it should have this x feature",. "overall nice but it could use an x feature " etc.
And boy what my journey was in the last 72hours.
Firstly my madhead laptop started killing me with the battery failures and constant hang.
Then my past asshole self tried to give me a middle finger. So i have this whole partition in my memory where i keep my Android stuff and apps. It has a special folder named published zone and i keep all my published app codes and related files there.
I was fairly certain that this app's code eill be also there,so i opened it, found the code and tried running it.
Turns out my asshole self had tried to mess around the code so much that all the db layer WAS fucked up, all the ui WAS changed and no code was working.
"Not to worry", i thought. I always use git and there would be a correct version some commits before. WRONG. I HAD CHANGED THE WHOLE FUCKING WORKING PRODUCTION CODE AND DIDN'T MAINTAIN A VCS!
Also this was the verbose and shitty java code my 1.5 year before self so loved to write, so it was taking me way more time to figure out what's happening in an already fucked up code.
So i tried a couple of ways to get back my working code :
- I tried looking for a google recommended solution. Those guys take my whole app code build and distribute via playstore, but they provide no means to retrieve back the original code.
- i checked my (occasionally) back up hard disk but no. My hard disk would have 100s of movies from 2016 , but not a useful piece of fuckin code.
- i also tried to get my apk and decompile it via some online decompiler. Here the google again fucks up and don't allow me to get my apk directly. Meanwhile i found a ton of shady websites which are hosting an apk of my app without my knowledge O_o . I tried to decompile on of them but code was even more non understandable than my fuck up code.
So i ended up looking at both the mess up code and decompiled code and coded the whole app from scratch ( well not scratch, i extracted the resources and some undamaged activities from the mess up code . Also github was down for more than 3 hours yesterday , at the same time when i was trying to look onto some repositories)
Lessons learned:
- DON'T FUCK UP WITH THE PRODUCTION CODE
- MAINTAIN VCS
- Your laptop is shit reliable, github is also shit reliable , so save code at multiple places.
- there are way more copies of your code lying on the internet than you think.

v0.0005a (alpha)
- class support added to lua thanks to yonaba.
- rkUIs class created
- new panel class
- added drawing code for panel
- fixed bug where some sides of the UI's border were failing to drawing (line rendering quark)
v0.0014a (alpha) 11.30.2023 (~2 hours)
- successfully retrieving basic data from save folder, load text into lua from files
- added 'props' property to Entity class
- added a props table to control what gets serialized and what doesn't
- added a save() base method for instances (has to be overridden to be useful beyond the basics)
- moved the lume.serialize() call into the :save() method on the base entity class itself
- serialized and successfully saved an entities property table.
- fixed deserializion bugs involving wrong indexes (savedata[1] not savedata[2])
- moved deserialization from temp code, into line loading loop itself (assuming each item is on one line)
- deser'd test data, and init()'d new player Entity using the freshly-loaded data, and displayed the entity sprite
All in all not a bad session. Understanding filing handling and how to interact with the directory system was the biggest hurdle I was worried about for building my tools.
Next steps will be defining some basic UI elements (with overridable draw code), and then loading and initializing the UI from lua or json.
New projects can be set as subfolders folders in appdata, using 'Setidentity("appname/projectname") to keep things clean.
I'm not even dreading writing basic syntax highlighting!
Idea is to dogfood the whole process. UI is in-engine rendered just like you might see with godot, unity, or gamemaker, that way I have maximum flexibility to style it the way I want. I'm familiar enough with constructing from polygons, on top of stenciling, on top of nine-slicing, on top of existing tweening and special effects, that I can achieve exactly what I want.
Idea is to build a really well managed asset pipeline. Stencyl, as 'crappy' as it appeared, and 'for education' was a master class in how to do things the correct way, it was just horribly bloated while doing it.
Logical tilesets that you import, can rearrange through drag-n-drop, assign custom tile shapes to, physics materials, collisions groups, name, add tag data to, all in one editor? Yes please.
Every other 2D editor is basic-bitch, has you importing images, and at most generates different scales and does the slicing for you.
Code editor? Everything behavior was in a component, with custom fields. All your code goes into a list of events, which you can toggle on and off with a proper toggle button, so you can explicitly experiment, instead of commenting shit out (yes git is better, but we're talking solo amateurs here, they're not gonna be using git out the gate unless they already know what they're doing).
Components all have an image assignable to identify them, along with a description field, and they're arranged in a 2d grid for easy browsing, copying, modifying.
The physics shape editor, the animation editor, the map editor, all of it was so bare bones and yet had things others didn't.
I want that, except without the historic ties to flash, without the overhead of java, and with sexier fucking in-engine rendering of the UI and support for modding and in-engine custom tools.
Not really doing it for anyone except myself, and doubt I'll get very far, but since I dropped looking for easy solutions, I've just been powering through all the areas I don't understand and doing the work.
I rediscovered my love of programming after 3-4 years of learning to hate it, and things are looking up.2
