Fick detta på mailen eftersom jag är prenumerant, det var lite utförligare än den publika artikelt så jag kopierar några delar.

...

Länge ägdes Råd & Rön av Konsumentverket, men för 20 år sedan togs bolaget över av organisationen Sveriges Konsumenter. Och nu är det alltså dags för ett nytt ägarbyte. Det innebär dock inte att Råd & Röns inriktning kommer att förändras.

Annonsfriheten och oberoendet ska bibehållas. Råd & Rön ska även fortsättningsvis ha en egen ansvarig utgivare, som alltså fortsatt fattar besluten om vad det är som ska publiceras.

...

En viktig bakgrund till Sveriges Konsumenters beslut att sälja tidningen är den mycket svåra ekonomiska situation organisationen befunnit sig under flera år. Men det har också varit helt avgörande vem som velat köpa.

Dagens Nyheter och Bonnier är en långsiktig medieägare som delar Råd & Röns publicistiska grundvärderingar kring trovärdighet och oberoende. Med en stark ägare i ryggen får Råd & Rön också utökade utvecklingsmöjligheter och också förutsättningar att nå ut ännu bredare.

Svenska konsumenter möts i dag av ett ständigt hårdnande bombardemang av aggressiv reklam, luriga shoppingsajter, bedrägeriförsök och ett enormt utbud av kassa prylar. Mot den bakgrunden är Råd & Röns oberoende journalistik viktigare än någonsin.

...

Självklart säger de att inget kommer förändras (de delarna jag inte tog med var ännu mer intygelser om att så var fallet), hur mycket litar ni på det? Det är lätt att påstå att Bonnier Group har bra "publicistiska grundvärderingar kring trovärdighet och oberoende" men hur långt brukar företags värderingar räcka i praktiken om det plötsligt skulle bli mer lönsamt att göra något annat? Jag litar inte på att ett företag står upp för konsumenters rättigheter mot företag för fem öre. Fast det som kanske förbättrar situationen lite i det är fallet är att Bonnier huvudsakligen håller på med media, medan Råd & Rön har mer fokus på fysiska produkter, matvaror och tjänster.

When buying your first car, would you pay extra to get a worse car so you have to learn mechanics in addition to learning how to drive? :)

It's definitely about finding the least bad printer if shopping the budget stuff, they all have issues as you say. Personally I think it's best to buy the printer which is the least likely to have severe design and/or manufacturing flaws and focus on learning how to get good prints out of it. When you're a complete beginner it's difficult to know if your print turns out bad because you're doing something wrong or if it's caused by a hardware issue.

Creality made good printers in the beginning, i.e. original Ender and Ender Pro. They used high quality components and offered good value for money compared to what else what available at that time. However, when they had cornered a large part of the market and got known as the brand that made the best beginner printers, things started going downhill. They switched from Meanwell power supplies etc. to cheap noname components, quality control seemingly became non-existent, and they released several poorly designed overpriced printers (E.g. the E3v2 - my first printer - and everything with "max" in the name).

I think there's a combination of different reasons for why there always have been so many people who believe that Creality make good printers:

  1. People who have bought their Ender 3/Pro before 2020 actually have good printers, and give them honest praise on forums.
  2. Fake reviews on the internet, which hype up the product since their only goal is for you to click their amazon affiliate link and buy it.
  3. Creality paying content creators for positive reviews, including several well known and otherwise respected within the community.
  4. Buyers who got lucky with the QC and don't own any other printers to compare with, might think their printers are the best.
  5. Buyers who are now happy with their Ender after having spent €100+ on "upgrades" and/or days of troubleshooting the printer. I've even seen a guy insist that an Ender is a better first printer than a cheaper more reliable alternative, because the 20 hours he spent on his Ender to get a decent print out of it gave him "an invaluable learning experience".
  6. And I've also seen people who haven't yet bought any printer claim that Enders are the best beginner printers, just because they've read that statement so many times they've come to accept it as a fact, and now they're "helping" others looking for a first printer by answering their questions.

I think my E3v2 is good now, but I've replaced the hotend, extruder and part cooling fans. I've added a second Z lead screw to fix gantry sag, and I found a manufacturing error where the X belt tensioner wasn't straight because tightening the screw into the aluminium extrusion bent the plastic (difficult to find, but luckily easy to fix with a metal shim). I've replaced the firmware with Klipper, controlled by a Raspberry Pi. And I've probably spent at least 50 hours just trying to fix and improve the printer, which I didn't mind btw, but I think most would prefer a printer which just works out of the box.

In retrospect, I wish I had joined some 3d printing discords and talked to experienced users before deciding on which printer to buy, and not relied so much on google, websites and random comments.

 

Jag tror jag ligger någonstans uppe i vänstra hörnet, vad tycker ni?

Semla and they are delicious

I was basically wondering if position and acceleration were considered different degrees of freedom, but I had it a bit mixed up. I've seen cheap 6 DoF boards with accelerometers plus something else to measure rotation IIRC, but these don't have absolute position and I was thinking if you add that maybe it would increase the degrees of freedom

[–] fhein@lemmy.world 3 points 2 weeks ago (1 children)

I don’t know about you, but lighting greatly impacts how the surface quality of my prints look. Hard/direct light at a steep vertical angle makes the faces look pretty rough, but more diffuse light coming from the side makes the parts look great.

It's normal, but I think it's more visible the thicker your layers are. I've also seen a respected 3d printing content creator use this effect to make his sponsored brand (Creality) look like it has higher print quality than the competitor.. If you're printing with ASA, perhaps you could use some light acetone smoothing if you want a more even surface?

[–] fhein@lemmy.world 1 points 2 weeks ago

If you enjoy building the Voron that's definitely a better deal (and I think I would) but if you're doing it to save money you have to factor in that time in the cost as well. I was briefly considering buying a Core One L after they become available with INDX, because it would be nice with a printer which includes everything and just works. But the VFA problems discouraged me, Prusa's suggestions to overtension belts and modified slicer profiles which try to avoid certain speeds feels like a bandaid solution to what is fundamentally a hardware design flaw IMO.

[–] fhein@lemmy.world 1 points 2 weeks ago (3 children)

Are we talking 3x acceleration and you're adding 3x position? I've heard the terms a lot but haven't really thought about which DoFs they're referring to.. Can't these devices also measure absolute rotation, so wouldn't that make them 9DoF?

[–] fhein@lemmy.world 2 points 2 weeks ago

Can't remember if it was Gnome 3 or Ubuntu Unity, but I think at least one of them had the intention of creating a unified UI for all types of devices.

[–] fhein@lemmy.world 5 points 3 weeks ago (2 children)

Very important. I spend a lot of time at my computer and my desktop environment is like my home. I want it to look in a way that I find aesthetically pleasing and it mustn't try to force me to change the way I work because some UX designer decided that their way was much better than everybody else's. Perhaps you can guess where this is going :D but I've tried to like Gnome 3 since it was first announced. I've given it multiple chances but it just doesn't work for me. It feels like they're going down the same road as all "modern" UIs, where only the most basic features are visible and everything else is either dumped into the "advanced" category or removed entirely. On the other hand, I have a coworker who only uses his PC like a tool, and he thinks Gnome is the best DE ever and can't understand why anyone would want something else.

Currently I use KDE and I'm pretty happy with it. It's highly configurable, and I've made it look and feel the way I want. I used mainly Xfce for a long time but now I prefer KDE.

It's funny if you know that it is parody, but it's so widespead in this day and ago so I tend to unconsciously filter it out. Tbh I probably wouldn't have clicked the link if I hadn't seen your comment, since I thought this was the original title of the video

[–] fhein@lemmy.world 1 points 1 month ago

I think you missed the part where it said "[...] cannot be overridden or otherwise defeated by a user with significant technical skill." I.e. either the printer will only allow flashing with signed firmware containing the detection algorithms, or it would have to be done by a separate chip which isn't affected by flashing firmwares.

But also detecting firearms in gcode is a ridiculously complex task, and if companies actually try to comply they might opt for building the algorithms into their closed source slicer instead, and then only allowing their printer to print encrypted/signed gcode. Or they might do the analysis using some AI algorithm on their cloud servers, requiring an always on internet connection to print things. It might be tempting to think that nobody would buy a printer like that, but I think that enough people will do if they make it convenient and cheap enough.

[–] fhein@lemmy.world 7 points 1 month ago* (last edited 4 weeks ago)

For a printer to be compliant, it mustn't be possible to bypass the restrictions. So your printer might not even be legal if it allows you to flash custom firmware.

identify and reject print requests for firearms or illegal firearm parts with a high degree of reliability and cannot be overridden or otherwise defeated by a user with significant technical skill.

 

Svårt att vara medveten konsument i dagens samhälle.. Inte nog med att många företag säljer varor av tvivelaktig kvalitet och/eller har dålig kundtjänst, dessutom har det blivit en stor industri att lura folk att köpa saker för att tjäna pengar på Amazon affiliate-länkar. En av de få saker vi konsumenter kan göra är att betygsätta och kommentera varor och företag, men vilka konsumentsajter litar ni på?

Pricerunner - Om jag inte minns fel så var väl Pricerunner den första sajten för att hitta de bästa priserna? Men jag tycker den har blivit väldigt dålig för att jämföra olika produkter, så det är väl mer när man vet exakt vad man vill ha som man kan hitta var den är billigast. Känns mer som en reklampelare för företagen som betalar för att vara med, men det kankse inte är så konstigt nu när den drivs av Klarna. Betyg: 2 av 5.

Prisjakt - Kommer ihåg när prisjakt först kom så var den ett grymt bra hjälpmedel att välja tekniska prylar genom att att filtrera på alla tänkbara egenskaper. Sen gick det väl inte så bra ekonomiskt, så den bytte ägare ett par gånger. Längs med vägen bytte de till ett mer "modernt" UI, dvs. mer ett flöde av produkter du ska köpa, och mindre fokus på att ge detaljerad info om dem. De tog de bort möjligheten för användare att rätta och komplettera produktinfo, så många saker saknar eller har felaktiga specifikationer. Lite då och då ger de också felaktiga priser pga. länkar till fel produkter. Ursprungligen en klockren femma, men nu ger jag den betyg: 3 av 5.

Råd&Rön - Svensk klassiker men kostar lite pengar att prenumerera på. Känns som de över lag har seriös testmetodik men de verkar inte bry sig om anti-features, t.ex. om en produkt kräver molntjänster för att fungera även om den inte borde det. Begränsade möjligheter att filtrera/söka produkter, man får lägga dem i en stor tabell och göra det manuellt. Betyg: 4 av 5.

Rtings - Väldigt teknisk testning av ett ökande urval av produktkategorier. Allt som går att mäta på en produkt mäts. Jag använde sajten för att hitta en datormus som passar mitt grepp, och de har till och med 3d-scannade modeller av alla möss vilket var väldigt användbart för mig. Tyvärr en betalsajt, men man får läsa 10 detaljrecensioner samt använda jämförelseverktyg gratis. En nackdel är att den har väldigt stort fokus på USAs marknad, och många testade produkter går inte att köpa här, samtidigt som europeiska märken kan saknas. Betyg: 4.5 av 5.

cpubenchmark - Inte riktigt samma sak, men väldigt användbar för att välja vilken CPU man ska köpa så den får ett hedersomnämnande.

 

I have installed CUDA Toolkit, which comes with its own Nvidia drivers etc. However, since the Nvidia drivers and tools from rpmfusion-nonfree-updates are slightly newer, Fedora tries to install those instead, which fails due to conflicts.

How can I prevent Fedora from trying to overwrite packages from the cuda-fedora42 repo with similar packages from rpmfusion-nonfree-updates? I would prefer not having to lock the package version, as I want updates when available in the cuda repo. I would also prefer to not remove rpmfusion-nonfree-updates entirely, since I get Discord and some other packages from there too.

 

A few years ago my wife and I built a computer out of old parts for her friend's then 10 years old son. Last month we were visiting them, and I heard the wife's friend say something funny that I thought I'd share with you.

They live on the other side of the city, this was the kid's first computer, and his mom doesn't have much computer experience either, so our goal was to build something that was easy to use and hard to break from the beginning. Originally I choose ElementaryOS since it seemed to fit the bill, but after a year or two it turned out that it couldn't be upgraded to a new major version without a full reinstall so it got stuck with an older version. We didn't visit that often, and the kid's games still worked so it wasn't a major issue until Factorio broke due to glibc incompatibility.

When his birthday was coming up last month we bought him a SSD to make the computer a little bit zippier without a major upgrade, and I thought I'd give him a brand new Linux experience too, so I asked for advice here and in the end chose Bazzite. While I was helping the kid with the installation, I overheard his mom saying in the other room:

This Linux thing.. We've never had any problems with it, he just clicks something to install it and it works. Unlike normal computers, where you always have to do things and fix them.

Perhaps not the most eloquent, but I consider it a very good review.

Couldn't find a dedicated community for distro recommendations, I hope it's ok to ask here.

A couple of years ago my wife and I built a computer and gave it to a friend's kid. We put ElementaryOS on it since that seemed pretty fool-proof, but it appears to require a re-install to upgrade major versions so it has been stuck with an old glibc and because of that he can't play Factorio.

For his 13:th birthday we bought him a SSD so it would be a good time to reinstall Linux, but is there perhaps some better choice than ElementaryOS? They live quite far away so I can't easily pop over to fix his computer if something breaks, we don't spend enough time there for me to teach him to fix things himself, and he doesn't seem very interested in learning how computers/operatings systems work either.

  • Hardware: Some old Intel CPU with 8GB DDR3 and a GTX1080
  • Usage: Gaming through Steam+Proton, Lutris and browsing.
  • Requirements: Games work, OS never breaks on updates. Doesn't need to be "kid proof", I don't think he touches any stuff he doesn't know what it does.
 

In case anyone isn't familiar with llama.cpp and GGUF, basically it allows you to load part of the model to regular RAM if you can't fit all of it in VRAM, and then it splits the inference work between CPU and GPU. It is of course significantly slower than running a model entirely on GPU, but depending on your use case it might be acceptable if you want to run larger models locally.

However, since you can no longer use the "pick the largest quantization that fits in memory" logic, there are more choices to make when choosing which file to download. For example I have 24GB VRAM, so if I want to run a 70B model I could either use a Q4_K_S quant and perhaps fit 40/80 layers in VRAM, or a Q3_K_S quant and maybe fit 60 layers instead, but how will it affect speed and text quality? Then there are of course IQ quants, which are supposedly higher quality than a similar size Q quant, but possibly a little slower.

In addition to the quantization choice, there are additional flags which affect memory usage. For example I can opt to not offload the KQV cache, which would slow down inference, but perhaps it's a net gain if I can offload more model layers instead? And I can save some RAM/VRAM by using a quantized cache, probably with some quality loss, but I could use the savings to load a larger quant and perhaps that would offset it.

Was just wondering if someone has already done experiments/benchmarks in this area, did not find any exact comparisons on search engines. Planning to do some benchmarks myself but not sure when I have time.

 

Update: Bug fixed in Plasma 6.3.1


Just posting this since I spent over an hour trying to figure out why I couldn't open my desktop today.. After booting and logging in I got a black screen. Switched to a terminal but did not see any obvious errors in the logs.

Not fixed for Fedora 41 KDE yet, so I installed plasma-workspace-x11 to use in the meanwhile. Anyone who hasn't updated to 6.3 yet could probably change their display settings to not use ICC profiles to avoid it.___

 

I just spent half an hour trying to figure this out so I thought I'd write it down somewhere in case it helps someone else in the future.

Aslain's modpack contains a whole lot of quality-of-life mods for WoWs, for example Battle Expert (formerly known as Navigator) which shows the exact relative angles between your ship and the enemy's. Almost feels like cheating to me, but Wargaming has endorsed this modpack and it even has a dedicated channel on the official discord server. Theoretically you have the same information without the mod, but it can be difficult to see how a ship is turning or changing speed by just looking at it.

These instructions are for when the game is installed through Steam, which looks like it uses some kind of overlay filesystem. This led to that the game install folder didn't show up for the modpack installer when I tried other methods.

  1. Install protontricks, I used the version available in Fedora's repos.
  2. Download the modpack installer from the official site
  3. Find the WoWs install folder in Steam. Right-click World of Warships in the Steam games list, select Manage and "Browse local files" and the folder should open in your default file manager.
  4. In a terminal, run the modpack installer .exe file in the game's Wine prefix. I'm not entirely sure this makes any difference compared to running it in a new prefix as long as it can access the game files, it mostly seemed convenient to me. The app id for WoWs is 552990 and it should never change, but you can get it with protontricks -l if you're curious. Change the file path so that it matches the file you downloaded and run:
    protontricks-launch --appid 552990 ~/Downloads/Aslains_WoWs_Modpack_Installer_v.13.6.1_01.exe
    It will print a lot of "failed to create" error messages for system dlls and exes, but that appears to be normal, and the setup window should open after a while.
  5. After some release notes etc. the installer will eventually ask you for the game's install dir. As far as I can tell, the game files do not show up anywhere on C:, but Steam mounts your Linux file system on Z: so we can use that instead. Browse to the game install folder, which we located in step 3, and select it. My install folder on Linux is
    /mnt/faststore/SteamLibrary/steamapps/common/World of Warships/ so I select
    Z:\mnt\faststore\SteamLibrary\steamapps\common\World of Warships in the modpack installer.
  6. Either manually select the mods you want or use the recommended selection. As I wrote before, many for these mods feel like they give you an in-game advantage over other players, but WG has said they're legal...
  7. The first time I ran the installer it hung on "Finishing installation". It appears to happen to a few Windows users too but the mod dev doesn't know what causes it. I noticed that there was a cleanup process running in Wine C:\windows\system32\cmd.exe /C DEL /s /f *.orig which shouldn't take so long time so I killed it (in Linux) and the installer continued. The next time I ran it this didn't happen, and it only took a few seconds to finish the installation.

If you have the game installed as standalone, e.g. Lutris, then I think you can just run the modpack installer in the same Wine prefix, and you should see the game's install folder under C:\Program Files as you would on Windows. I.e. select the game in Lutris, click the tiny arrow next to the wine glass button and select "Run EXE inside Wine prefix" and then choose the installer you downloaded. But I haven't done this so I promise nothing.

Please don't take this as an endorsement of World of Warships, I borderline hate this game and only play it because some of my friends are obsessed with it. The gameplay is a bit too slow paced for my taste, there are a lot of hard counters which you can't do anything about in random matchmaking, and carriers (planes) can turn any game into pure suffering. I also dislike the game's monetization scheme, lootboxes are expensive and most have a tiny chance to give something really good and a big chance to give you complete garbage. The game might be f2p, but at higher tiers it becomes unplayable without a premium subscription (€10/month) since ship maintenance gets more expensive than your earnings. To maximize your ship's performance you need a high level captain, expensive modules and also buffs which are consumed each game. My friend tries to argue that the game is not pay-to-win because you can also grind ingame resources to buy those, but you'll spend many hours playing at a disadvantage if you don't buy your way past it. Just my personal opinion of course.

If you despite my warnings felt an urge to try this game (honestly I thought it was quite fun at lower tiers) then check if any of your friends are already playing it and ask them for a referral code. Both of you get free stuff from being recruited by someone else and once you've created an account it's too late, unless you stop playing completely for 3 months. If you do that it is possible for your friend to send you a recruiting link if you want to start playing again.

Just a heads up, I've read that it's impossible to connect an existing wargaming.net account to a Steam account on Linux, so make sure you authenticate through Steam when you create the account if you plan on playing it through Steam. Though if you have Windows dual boot then I think you can link the accounts there if you need to.

 

Going through some boxes and found a stack of old White Dwarf. I'll keep the first issue I ever bought as a memory but planning to get rid of the rest. Just wanted to check if there are people collecting these before they go into the recycling bin. If anyone's interested I can make a list of which ones I have, and I'll send them to anyone willing to pay for postage. Located in Sweden.

 

Any games with less than 1000 total Steam reviews you've enjoyed and thought more people ought to know about? Not a hard limit, just a guideline for what could be classified as "undiscovered" on Steam, assuming it wasn't released yesterday.

I would recommend:

  • Full Bore, a cute block-based puzzle platformer. Solid mechanics, level designs and even a somewhat engaging story. ~~Unfortunately hasn't been on a sale since 2021 according to steampricehistory.com, while it was frequently reduced to €2-3 before that. Not sure I'd recommend it to everybody at full price, but IMO it's one of the best indie platformers I've played.~~ edit: Did someone email the creator of Full Bore or something? It's suddenly on sale again, for the first time in ages :) Go buy it!
