  • It is an absolute crock of shit.

    There is plenty of research on magnetism and humans and it doesnt need a new title and niche “research” from a frankly failed state like Russia.

    We use high Tesla fields routinely every day worldwide in hospitals in Magnetic Resonance Imaging. Safety of this technology has been and is continuously investigated. There has also been extensive investigation of magnetic fields related to power lines and other use cases.

    There does remain some uncertainty and controversy around potential effects of long term exposure to low T electromagnetic fields but its long established that short term exposure is safe.

    This “research” is more on the realm of autism vaccine science. A lot of money can be made in niche fake sciences both in the industry of research itself and then the crap they can sell to ignorant people as a result.

    Russia as a state has been systematically destroyed over the past few decades and most of its institutions have a terrible reputation now. While there are undoubtedly still good scientists in the country, they are working in a gangster state and many of the best minds have long fled for better opportunities abroad.


  • Most people expect a GUI interface to get into their desktop. But you dont have to use one if you dont want. SDDM can log into any desktops you have - KDE but also Gnome or XFCE etc. It can also help select X11 vs Wayland sessions.

    There are alternatives like LightDM if you dont like SDDM. Or TTY is fine too. But generally they’re not large pieces of software and while they are undoubtedly bloated from what they could be, they are still small and lightweight in the era of Tbs of storage and Gb of memory. The savings you’d get in not using them would be small on the scale of the rest of the OS. Obviously they’re useless for none GUI machines / servers.

    They’re called display managers because historically the concept was added to X11 system where you’d have a stand alone X terminal running locally for the end user with an X server which would then connect to an X display manager on a central machine. This was in the Unix days and shared spaces like governments, universities or corporations and the set up was potentially less hardware intensive allowing cheaper X terminals and an expensive central server.

    The concept has gone now - PCs are vastly more poweful and can easily run the entire OS locally, and thin clients are the modern set up if you do want terminals/clients and central servers. The most common scenario is now the display manager running on your local PC, alongside everything else and essentially replicates the TTY login in a GUI form. So yes its basically a session manager but the name is historical and probably won’t be going anywhere fast.



  • I’m not sure this true - PDF is an open standard. The issue isn’t generally with layout and reproducibility - a good PDF maker and a good reader will give you an accurate representation of how it looks on all devices once the PDF is created.

    Certainly there isn’t a dedicated FOSS tool for make PDFs; Libre Office and Inkscape do a decent job but not perfect which may be what you’re referring to. And they’re not dedicated PDF makers plus the real problem is building fillable forms and signature tools.

    But there is a proprietary alternative called Master PDF that is a dedicated and supports all the PDF standard features I believe; one perpetual license is $80 compared to Adobe subscription based charging. I’m not aware of other options myself but they may exist. But it’s a viable alternative to the “adobe tax”.

    Also of course if you have Office 365 from Microsoft, you can use Word to export docs to PDF reliably (in my experience). Obviously as far as you can get from FOSS, but it is an option on Linux via web browser if you have it from work for example; at least you don’t have to pay Adobe but it’s scraping the bottom of the barrel for this threat I know!


  • Firefox can do basic annotating, adding text and adding pictures but it can’t make a new PDF from scratch.

    You may be confusing Adobe Acrobat Reader with Adobe Acrobat? Full Acrobat is the proprietary tool to make a PDF file from scratch including some of the more complex functions.

    PDF is an open standard and has been for a while, so there are now plenty of alternatives for most of the functions. LibreOffice Draw and Inkscape can do a lot of PDF creation functions but not all. There are also “print to PDF” options to create basic PDF documents too.

    However some of the more niche functions are not widely supported or well supported; and there isn’t really any opensource dedicated PDF maker that I’m aware of. Layout tools are abundant but I think it’s things like building forms and document signing that is less easily replicated. There is Master PDF - a fully functional PDF maker which is proprietary and available for Linux; it $80 for a perpetual license. I’m not aware of any other alternatives myself.

    If your linux OS supports secure boot then it does help improve security.

    The differing opinions on it are often because it can cause issues in some set ups and in a default set up its only a marginal security gain.

    It will add a layer of security at boot by preventing 3rd party unauthenticated processes / software from running and creates a secure boot chain from your BIOS up to the OS. But the default set up also means other authenticated OSes like Windows can be run, so its not as secure as it could be.

    To really secure it you could create your own keys and then only your OS could boot. But as a linux newbie thats likely way more than you need and there are risks if you fuck up, to the point of accidentally locking you out of your own machine

    So your choice is really just the default set up being on or off. On is a bit more secure but if you experience any issues then turn it off and don’t worry about it.

    Its not doing nothing. Linux uses a Microsoft provided key for initial BIOS authentication and then has its own tree of keys that it uses for security. So it does have the benefits of locking out malicious code/processes evenninna default set up.

    Using your own secure boot and TPM keys is certainly more secure, but it doesnt follow that secure boot with the default set up is doing nothing to help secure your system at boot.

    Linux supports secure boot so if a distro supports it it’s worth using it.

    Linux can use a key signed by Microsoft in a preboot loader and then itself perform its own key authentications for all other processes and software (a shim), forming a secure chain from the BIOS up during boot. You dont have to play with creating your own keys.

    So if your OS supports secure boot it is worth using it for added security at boot. Its far from perfect in this set up (as there are plenty of windows OS that also have permission to boot) but it is better than a free for all without it even if the risk is low for most desktop users.

    You can go further and generate your own keys and use secure boot and TPM together to lock down the system further but you dont have to to get some benefits from secure boot.

    So I dont own one but was interested in what could be done.

    As far as I can see the 3rd gen model is less versatile than the 1st and 2nd, because its so locked down and has very limited storage. Its more like an iPhone than a PC.

    However apparently it can be jailbroken and Kodi installed onto it: https://github.com/NSSpiral/Blackb0x

    Jail breaking means “unlocking” the restrictions apple put on the is on the device so you can do more with it.

    But this project is last updated in 2021 and from the looks of it online, fundamentally there isn’t much more that can be done. Jail breaking it would be a first step to do anything with it if you want to experiment.

    Kodi would certainly give it a new lease of life but that still keeps it as a media consumption device. Kodi is an open source media tool that has a good TV friendly interface, and a huge range of plugins for streaming video and audio (legally but also illegally; kodi itself is perfectly legit and legal but there are plenty of plugins that essentially allow media piracy). You could then sell it on eBay if its working? Someone might want it even if only for cheap?

    Other than that, recycle it? If your local refuse centre doesnt recycle it some companies might?



  • It honestly seems very unpredictable. Anecdotally the worst behaviour seems to have been at the most republican states but not exclusively.

    For example the Australian who had a work visa and lived in the US for years flew in to Texas where it was arbitrarily nullified. There are plenty of stories of people crossing southern and northern borders and being detained by ICE. Thats included British, German, Australian and French cirizens that ive seen in the UK press coverage anyway.

    As a US citizen you shouldnt have an issue but I’d probably travel through a major hub like JFK in New York to be safer. I wouldn’t re-enter through Republican states like Florida, Texas, nor probably Washington DCs airports. Obviously travel on your US passport.

    You should he OK as a US citizen but it does look like there is a breakdown in the rule of law in the US. People imagine that means riots and the police not able to keep control, but in this case its the government and government agencies doing whatever they want and the legal system unable to stop them.

    I’m a UK citizen and am not intending to travel to the US - I often cone for a major conference but having seen what happened to the French scientist who had his phone searched and then was denied entry for criticising Trump I won’t be risking it. I’m sure a lot of other UK and Europeans feel the same way.

    Sadly the only 100% safe option for you is to not leave the country. Its madness as youre a US citizen but at this point things are still going through the courts and its not clear where this will stop.



  • You can’t directly convert the app to make it natively android; android is too different for that. The app is built to use the whole android OS, not just the kernel (which is forked from linux). That means the android app is designed to run on mobile processors (usually ARM), and will be making calls to the android OS for everything.

    You can’t repackage it directly as a linux app. However there are emulators and translation layers that cannbebused to run android apps within linux.

    Waydroid for example allows android apps to run using android containers in linux. Anbox is also a container approach to running android apps. Both these approaches essentially translate for the android apps, and reduce the overhead asnthey dont have to emulate everything and can directly pass instruction to the linux host system. You can also use full virtualization to emulate an android device and run a whole virtual device. This would have a bit more overhead though.

    I’m not aware of tools that can be used to compile android apps from source in to linux apps. It could be done in theory but would be complex due to the degree of translation of android APIs needed. Again compiling into some kind of container approach (I. E. Compile to include anbox or waydroid) might be doable but would bloat the app. I dont think there is the demand for that kink of approach when building in containers into Linux (and Windows) allows direct reuse of the android apks.


  • If youre new to linux, then I’d say Linux Mint is the place to start. Use it with XFCE if light weight is what you want.

    Not having cutting edge packages is a red herring - you really dont want bleeding edge as thats where the errors and breakages happen. Mint is reliable and secure which is what you need when starting out. You dont want to be a beta tester. Dont confuse latest packages for most secure on linux - plenty of packages have stable older versions which get security patches.

    Mint is also very popular, with a huge range of easy to find resources to help set it up the way you want it.

    Wayland is also a red herring - its the future but its just not really ready yet. Yes its more secure due to how its built but the scenario you’re using linux in the particular security benefits you’re hearing about are not really going to impact you day to day. And the trade off is that Wayland is still buggy, with many apps still not working seamlessly. Most apps are designed for X11 and x-wayland is an imperfect bridge between the two. I’m not saying Wayland is bad - it’s actually good and is the future. But you dont want to be problem solving Wayland issues as a linux newbie. Dont see Wayland as essentialnfor an good stable and secure linux install.

    Personally I wouldn’t recommend Fedora - it has a short update cycle and tends to favour newer bleeding edge tech and paclages. Thats not a bad thing but if what you want is a stable, reliable low footprint system and to learn the basics, in wouldn’t stray into Fedora just yet. It has a 13 month cycle of complete distro upgrades and distro upgrades are the times when there are big package changes and the biggest chances of something breaking. The previous version loses support after a month so you do need to upgrade to stay secure. Most people won’t have issues between upgrades but with any distro when you do a big upgrade things can easily break of you’ve customised things and set up things differently to the base. It can be annoying having to fix thongs and get them back how you want them, and worse can lead to reinstalls. Thats nor a uniquely Fedora problem, but the risk is higher woth faster updating and bleeding edge distros. And in fairness there are lots of fedora spins that might mitigate that - but then you risk being on more niche setups so support can be harder to find when you need it.

    For comparison the latest version of Mint supported through til 2029, and major releases also get security patches and support for years even after newer versions are released. There is much less pressure to upgrade.


  • I work in a hospital and the worst days to work are weekends. The hospital is still full of patients but most staff are off so its busy. And its much harder dealing with sick patients and emergencies on a weekend as a result. Also all your friends and family are off on the weekend so you can’t see them.

    Meanwhile if you have days off in the week, it’s great because everything is open (unlike a sunday) and all the kids are in school. So you can go out an enjoy the parks, or venuesnlike gyms or shop freely etc. But most of your friends and family are also at work so that limits things.

    I would definitely take 2 days off together, not split them. If I were to have 2 days off and work every weekend I’d either take Mon/Tue off or Thu/Fri. I think its just preference and howbbusy your job is. It could suck being in work on a Friday while everyone else is gearing up for weekend off and discussing their plans, plus also people head off early where they can - I’d probably take Thu/Fri off so I didn’t have to put up with all that.

    I personally work 80% of full time and do 3 long days plus oncall. It works out 3x 10 hour days and 2 hours pay per week is for my weekend oncall work every 16 weeks. I end up with 4 days off every week and its glorious. So aiming for a 5 day week may be a mistake. When I was 100% full time I did 4 long days for a bit - it was OK but I had Tue off, worked the other days and had the rhythm of weekend off then on/off/on - it didn’t feel like i was really off for 3 days a week. I’d definitely recommend always stick off days together.

    But it may be longer daysnis the real best option if available. Even working 100% hours you have 1 less day commuting on 4 days, and if you work 10 hours so you start early and finish late you can even miss rush hour. I used to stay late or come in early to miss traffic when i was doing normal 9-5 work so switching to 10 hour 8-6 was easy. Depends what your role is and your own stamina for long days is though.


  • I’m a UK based professional and I come to the US for a conference each year. I won’t be coming again.

    I dont want to have my phone searched at the border, I dont want to risk arbitrary arrest and detention without legal representation, and frankly I dont want to spend my money in the US anymore (its a week long conference and costs a couple of thousand pounds including conference fees, flights, hotel and expenses). I’m already trying to buy European because of trumps other behaviour, so not spending mony in going to theUS is an easy win too.

    Now multiply that out - even if its a small percentage overall there are lots of people who are no longer going to want to visit the US in the current climate. Expect a downturn in US tourism guvent the horror stories that are coming our of US ICE detention centres.
