Hi all,

There is a tar.gz whose contents I would like to access. The file itself is quite old, last being updated ~20 years ago if I had to guess (I am not sure if this is relevant). The file contains legacy scientific code that I would like for archival purposes and can be found via the "code site" link here. However:

• When I download the file and run tar -xvzf radpack.tar.gz I get an error: tar: Error opening archive: Unrecognized archive format.
• Likewise, if I try to gunzip it I get gunzip: radpack.tar.gz: not in gzip format.
• Running file radpack.tar.gz only yields radpack.tar.gx: data, indicating file cannot find anything out about it.
• head radpack.tar.gz outputs a string of unintelligible unicode.

These are the different solutions I have come across after searching this problem, and to me is good evidence that the file has been corrupted in some way and that may very well be the case. However, for archival and historical purposes it would be great if I could access the contents, so I am compelled to search out other solutions. Are there other options I can try here? Is there some way to confirm that the file is in fact corrupted beyond recovery? Any help on this point would be greatly appreciated. I posted this on stack exchange as well but figured maybe the smart folks here might know.

EDIT:

Just to be clear this has been solved — a functioning copy of the archive was found.

What have you been watching and reading this week? You don't need to give us a whole essay if you don't want to, but please write something! Feel free to talk about something you saw that was cool, something that was bad, ask for recommendations, or anything else you can think of.

If you want to, feel free to find the thing you're talking about and link to its pages on Anilist, MAL, or any other database you use!

I'm in the market for another EV. I have a Leaf currently and love it for in town driving. I want something with more range for longer trips.

I've looked at Hyundai, Tesla, VW, and Ford vehicles. No vehicle is perfect. I like the HUD of the Hyundai and the full self driving of the Tesla. I don't like the look of the Ford Mustang, and the Lightning is comfy but enormous. And since Tesla has been around for a while, there's the option of a used Model S compared to a new Model 3 (for instance).

This doesn't necessarily have to be an advice thread - trying to find the best vehicle for me. I'm more looking for your personal pros/cons of vehicles in the EV market from your perspective.
Like the title asks, what would you buy in today's market?

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

Find yourself watching tons of great videos on [insert chosen video sharing platform], but also find yourself reluctant to flood the Tildes front page with them? Then this thread is for you.

It could be one quirky video that you feel deserves some eyeballs on it, or perhaps you've got a curated list of videos that you'd love to talk us through...

Share some of the best video content you've watched this past week/fortnight with us!

Well, a few minutes ago I finally pushed the button, the game is released. So I wanted to write a short write up of some things that I had to do to release the game. I won't really talk about making the game itself too much, more about the part of actually releasing the game, if you are interested in more of that you can see my posts from Timasomo (1, 2, 3, 4, showcase).

Steam

I have already created many games in the past, I've been making games for more than 5 years, but always as a hobbyist. So I never experienced releasing a game on a platform like Steam. I have to say working with Steam and Steamworks is very pleasant and streamlined, but it is still much more complex than for example releasing a game on itch.io, which is what I did before for all my other games. I'll try to summarize how the process looks like.

First, before you can even get on Steam, you have to register, fill out a ton of paperwork, wait some time for it to be manually approved. Afterwards, you have to pay the 100 dollars for Steam Direct. At this point you finally get a Steam app id, which you can use to start integrating Steam features into your game. For example, having achievements, Steam cloud integration (so the saves get synced between devices), leaderboards and potentially more, especially if you are making a multiplayer game. To make my game I am using Godot, and I found a C# library called Facepunch.Steamworks which made this all quite easy, I'd definitely recommend it if you are using Unity or Godot with C# and want to release your game on Steam.

Before releasing a game on Steam you also have to finish everything on a gigantic checklist, including things like: uploading 10 various header, capsule and other images which are used on the store page and Steam library. An icon for the game. What are the minimum requirements required to run the game, whether the game has adult content, whether it supports controllers, how much the game will cost, screenshots, a trailer, there are just so many things to do! And when you complete parts of this checklist you have to have your game go through manual reviews. Each review could take about 3 days to get done. I failed one review first so I had to resubmit it too and wait again. Let me tell you, if you plan to release a game on Steam, reserve at least a month to do it, and start going through the reviews as soon as possible -- actually I think there even is a minimum of a month before you can release the game from the day you get an app id.

Trailer

Creating a good trailer is super hard. I am not a video creator/editor at all, but luckily I at least own a solid program for creating videos -- Vegas 14 pro, that I got for super cheap in some Humble bundle about 8 or something years ago, so I at least had a good start there. I ended up with not that complex of a project and Vegas still kept crashing when rendering, so I am not sure if I'd recommend it though.

The hardest thing for a trailer is deciding what to put in it for me. I know that a trailer should be super short, should showcase how the gameplay looks, what are the features and so on, but when I got to actually making it, it was still super hard to decide what to put there. How do I even start? I watched a ton of other indie game trailers to get some inspiration and that also didn't help that much. There are some trailers which are really just gameplay, some trailers which are actually just incredible with editing I could never do as a pleb... So I started with something that I know a bit more. I created a very short music track, and decided that I will just edit the trailer to fit the music.

The music track basically splits the trailer into 4/5 very short sections:

• Basic gameplay, how the game looks when you start playing it
• Explaining the roguelite part of the game, selecting spells and items
• More complex gameplay, how some combinations of spells and items can look later in a run
• List of features
• Special bonus ending section showing a "Legendary" spell, which should show how insane spells can get, followed by the logo of the game

I think the trailer ended up being not too bad, but I still had some feedback that it isn't flashy enough. And it's true, but I am not really sure how to improve it easily. When watching the Vampire Survivors trailer for example I can see that they did a much better job: it's so much more dynamic, the music really pumps you up, it's overall better edited, it has cool transitions, camera movement and so on.

End

Releasing a game on Steam was a great experience. I learned so much! I basically made this game over weekends and evenings, since I also have a job. To try maintain my productivity I tried to do at least some work on the game every single day. I have to say that towards the end I started losing some steam (haha), some days scrambling to do at least something late in the evening before I went to sleep. But, if at least someone plays the game I think I want to keep updating it more, I still do really like the game!

Thanks for reading! Feel free to ask me anything about the game, or the game dev process, or about anything basically haha.

Here's the Steam store page, the game costs 5 dollars, I'd love it if you checked it out. If you want to play the game but can't afford it PM me and I'll send you a key for the game (at least once I get the keys I requested -- did you know that Steam has to approve the creation of keys manually? Edit: the keys are now ready)

Have you watched any movies recently you want to discuss? Any films you want to recommend or are hyped about? Feel free to discuss anything here.

Please just try to provide fair warning of spoilers if you can.

Recently on here someone recommended a game called travle, which is a lot of fun even though I suck at it, as do my friends who play. Can anyone recommend other similar "one puzzle per day" style games?
