Google Maps can now navigate inside tunnels, like Waze does, using Bluetooth beacons
A new feature spotted by SmartDroid allows the Android version of the app to use Bluetooth beacons to track your location in areas where GPS signals typically can’t reach.
These beacons transmit Bluetooth signals that give location data to your phone, according to the Google-owned Waze, which already supports the feature. The app then uses this information along with the device’s mobile connectivity to “provide real-time traffic data as it would with a typical GPS connection.”
The only caveat is that the feature will only work if the tunnel you’re travelling through has Bluetooth beacons installed.
So, this is going to depend on whether these beacons exist in your tunnels and whether there is a partnership in place. But for commuters that regularly travel through long tunnels, this could be pretty useful. It does seem, too, that Waze on iOS already also has this functionality.
I would think though that any static Bluetooth, or even Wi-Fi SSID, could be used to determine locations, if the app knows which of those beacons are located where.
Why would you actually need to know where you are inside a tunnel? I'm not sure, but it sounded like an interesting way of using existing technology to fill some empty gaps.

PicPlanner: Open-Source Linux app for Calculating the position of the Sun, Moon, and Milky Way to plan the perfect time to take a Picture
People who love to photograph know, that the biggest problem is being at the right spot at the right time. Therefore, landscape pictures should be planned before visiting the place of choice. To plan the location it is important to know the position of the sun, moon, and sometimes also the Milky Way. Where to find the sun at which time is most of the time easy to guess, but when (and in what direction) is the sunset? And for the Milky Way, normally nobody knows where to find it in the night sky at which time at a specific location. This small program should answer all these questions.
But it is not just for landscape photos, as portrait and night photographers will be just as interested in this information.
It is a GTK app that can be complied from source, but I also see some repos, such as openSUSE and the Arch AUR, have already included it. There is also a Flatpak file supplied. It should also run fine on any Linux phones.
Being open source, it may also be of interest to many, to see how the insides work. The source code does have quite a bit of commenting explaining what is going on.

Guide to lossless audio: Everything you need to know from a smartphone user perspective
Lossless audio is essentially just audio that's presented in its purest form, exactly as the artist intended it to be heard. Vinyl records are a great source of lossless audio, as the records themselves are nothing but analogue media that capture every part of an analogue wave in their grooves. The analogue sound of these records sound closer to how artists sound live, and is significantly different from the digital audio that most of us listen to these days. Modern-day solutions offer a convenient way to access huge libraries of music from anywhere at any given time. But this added convenience affects the overall quality of the music.
Most of the music we listen to these days is heavily compressed to save space on our devices or consume less mobile data while streaming. This compression can significantly degrade the audio quality. If you wish to listen to music in its highest quality, just the way the artist intended, lossless audio is the answer. But what is lossless audio anyway? Is it significantly superior to MP3 and other compressed audio formats?
Most audio files you download from the internet these days are generally in MP3 format. This format is popular since it's widely supported across multiple devices without any compatibility issues. However, MP3 is a compressed audio format, which basically means you're losing out on some information that you may otherwise hear on a lossless audio file. The reason we say may is because even some audiophiles claim they cannot differentiate between 320kbps MP3 and a lossless format like FLAC. Audio streaming services also use a format known as AAC which will usually sound better than MP3 at the same bitrates.
And not all lossless audio you hear is uncompressed...
Quite an interesting post, and it shows too, that a lot will depend on the actual music/audio service you're subscribing to, or when you source your digital audio from. That source largely decides what quality audio you're going to be able to access.
And the article also explains why your lossless audio source is not going to be experienced that way on any true wireless Bluetooth earbuds, no matter how expensive they are.

Casy Newton's Platformer is leaving Substack for Non-Profit Open-Source Ghost Publishing Platform
Ghost is a powerful app for professional publishers to create, share, and grow a business around their content. It comes with modern tools to build a website, publish content, send newsletters & offer paid subscriptions to members.
Publishers can deliver posts by email newsletter to their audience, so they’ll be in the loop whenever something new goes live. They can segment their audience and send multiple different newsletters based on preference. In others words you can have topics handled separately from each other for better focus.
Ghost makes it easy, with native signup forms that turn anonymous views into logged-in members. It allows people to sign up for free, or purchase a paid subscription to support a publisher's work across monthly and yearly premium tiers.
Ghost's main service is a paid service, this is how they keep the service sustainable and keep innovating the product. Many publishers also do not want to self-host as this also costs some money (hosting, fast CDN service unless you use Cloudflare, e-mail management, backups, updates) and some additional effort by the person self-hosting. I'm guessing too why they don't offer free publishing is because then they follow the "Google" route of including intrusive adverts and 3rd party tracking ("free" has to be paid for by someone!).
However, you can self-host Ghost on your own server, computer, or Raspberry Pi to have full control over your production environment.
Ghost uses Strip as the payment partner for reader subscriptions so you'll need to be sure you can access/withdraw funds from there if you want paying readers.
Ghost has provision for a wide array on integrations with services such as Zapier, Stripe, Discord, Slack, YouTube, X, PayPal, Mailchimp, Disqus, Google Cloud, LiveChat, Giphy, Twitch, SurveyMonkey, Amazon S3, Buffer, and many more.

US FTC bans data broker from selling Americans’ location data - Only Americans?
"Geolocation data can reveal not just where a person lives and whom they spend time with but also, for example, which medical treatments they seek and where they worship," said FTC Chair Lina M. Khan.
It's a reminder again why so many are very sensitive about their metadata. Geolocation is only one form of metadata, and it is not about where you are right now. It's about all the places you visit and what the associations are with those places. When matched with other people's geolocation data, it shows who your friends are, who you work with, when you go to what religious institutions, where and when you shop, and it goes on and on.
These data brokers specialise though in putting lots of different metadata together to form the fuller picture. That information is worth a lot of money.
"As AI models further incentivize firms to vacuum up people's personal data, placing limits on how firms can track and use sensitive information is paramount," FTC Chair Lina Khan said.
I get that the FTC only has jurisdiction over US companies, but if these brokers are on US soil, or are owned by US companies, then the ban should extend to everyone's data not being sold in this manner?
As of October 2023, Outlogic (formerly X-Mode Social) no longer exists as a separate company. It was acquired by Vertafore, a United States-based insurance technology company, in March 2023. However, Vertafore's headquarters are located in Denver, Colorado, making the US the effective "country" of the data broker, albeit indirectly through its parent company.
It appears then to be a US owned company that is gathering and selling this data. The big question then is why is it being implied that they can still sell non-Americans data?

Atuin is an open-source shell command history app for Linux with syncing, unlimited history, and with contextual search
Atuin replaces your existing shell history with a SQLite database, and records additional context for your commands. With this context, Atuin gives you faster and better search of your shell history!
Additionally, it provides optional and fully encrypted (E2EE) synchronisation of your history between machines, via an Atuin server, or you can self-host your own server. There is a single command to easily delete your data from the server too.
It supports zsh, bash, fish, and nushell shells right now.
The search is as easy as pressing the up arrow in the terminal and then scrolling back, or typing to search. But you could also type something like this to do a search [search for all successful `make` commands, recorded after 3pm yesterday
atuin search --exit 0 --after "yesterday 3pm" make].
Atuin offers configurable full text or fuzzy search, filterable by host, directory, etc. As it has context around dates, times, exit code, and even the directory location form where a command was executed, you could use the -c flag to just search for commands run in a particular directory.
The sync function allows you to have the same history across terminals, across sessions, and across machines.
There is a quick start script that can be run to install it, otherwise you can also install from the various Linux repos. For manual installation, the steps I found to get going were:
* Install Ble.sh and add it to your .bashrc (or other shell) file
* Install Atuin and add it to your .bashrc (or other shell) file (after Ble.sh)
* Restart your shell and run 'atuin import bash' to import my bash history into Atuin
* Press up arrow to see if Atuin interactive search triggers
The link below has some good documentation as well a link to their source code.

Mbin is a fork of kbin: a decentralized content aggregator running on the Fediverse network
Mbin is a decentralized content aggregator, voting, discussion and microblogging platform running on the fediverse network. It can communicate with many other ActivityPub services, including Kbin, Mastodon, Lemmy, Pleroma, Peertube. It is an open source alternative to other link aggregator services like Reddit. The initiative aims to promote a free and open internet.
Mbin is focused on what the community wants, pull requests can be merged by any repo owner (with merge rights in GitHub). Discussions take place on Matrix then consensus has to be reached by the community. If approved by the community, only one approval on the PR is required by one of the Mbin maintainers. It's built entirely on trust.
It seems its claim to fame is being more open and accepting of community changes and improvements. It can install as either bare metal/VM or as a Docker container.
Although anyone can install it and self-host it, their project page also contains a link to various instances that already exist and which anyone can register on.

Possibly true on that last prediction, but I predict we're going to lose a lot of what is being created right now by then. I think our generation (between vinyl records and memory crystals) that will have lost a lot of memories. A lot of them sit on hard drives in private homes, and at businesses that go out of business, etc.
Dutch startup Nuwa claims to have invented the world's most advanced smart pen that writes on plain paper
Nuwa plans to launch the device this March. The Groningen-based company today announced a fresh cash injection of €1.5mn to boost the development of the product, which uses an inbuilt camera system, motion sensors, and algorithms to capture text written on paper.
Nuwa is targeting the product at people who still enjoy writing with a pen and pad, as the device writes on plain paper using regular ink cartridges. So, it is a fully normal writing experience.
To digitise the text, the system uses three tiny cameras with 2mm x 2mm sensors. All the data is then processed directly on the device. It exports to PDF, SVG and more formats will be announced.
So, like my previous post today, many will wonder where the data goes. Does is export directly from the local device/app to where you want it, or is someone watching the cameras? If I point my pen at someone, will it take spy photos? We'll probably only know more of this detail after the device has been released and tested by others.
Their website's privacy policy does though state that they collect and process personal information in strict compliance with Dutch law (i.e. EU laws). This is stated as personal sales and contact information, not the data that you produce with the device.
But with its normal price being US$373 it's possible also that it pays for itself through the sale of the device, and not the sale of the data.
The Nuwa Pen does not require a subscription to work. However, the optional subscription (priced at $2.99/month) covers the costs associated with advanced features like Augmented Notes and Text Conversion, and this will likely require data to be passed to a cloud service for processing. So, it's important to note that what you are getting locally is merely a digital scan of what is written. The subscription cost covers any conversion to text.

Open source's new mission: To boldly go where no software has gone before and expose where the data goes
An interesting read (linked below) in that often the code used to run an application is available as open source, but not always understood by users. The thing that users worry about more though is where their data actually is, and where is it flowing (in plain simple to understand language and pictures).
It's true that many FOSS apps are completely open, and the data is stored locally only, or sometime synced via a 3rd party service that the user chooses themselves. But Big Tech has also found ways of gaming the FOSS environment to the point where their solution is FOSS in name, but the server/cloud side is not open sourced, and the users' data is stored in that cloud service somewhere without the user really knowing where it is, who/what else has access to it, etc.
It is being proposed that a truly open system should also extend to the user's data, and not need a programmer to try figure out what is happening. In most cases the client side open source app is not going to give any ideas as to what is happening with data on the server/cloud side.
Usually, such data also does not conform to open data standards, and even when it does, it certainly can't easily be re-used elsewhere by the user. Yes, you could export your Google+ user data from Google, but there was nothing you really could do with that data.
Contrast this with a simple example of say a cloud hosted RSS reader service. You can export the OPML file and import that into any other RSS reader as the data conforms to an open standard.
To be truly FOSS the whole system needs to be able to be self-hosted by the user, and the location and the access to the data needs to be understood by users. The user's experience is the total sum of the application software, the server/cloud side software, as well as their data.

7 Tips and Tools to Improve Your Gaming Experience on Linux
Thousands of games now work on Linux, thanks to all the new tools available and user experience improvements by the distributions. However, there are certain tools, tips, and techniques that you should follow to get a seamless gaming experience.
These are pretty practical tips. It's true you don't want bleeding edge brand new hardware as driver compatibility on Linux often takes 6 to 12 months to catch up. I've always found that narrowing my selection of new hardware to devices that are open standards compliant, or already well supported, goes a long way to a trouble free experience.
On the software side, Steam Games have worked well for me as you can buy once and play the game across different platforms. But the higher end games I've enjoyed such as Snowrunner and Red Dead Redemption 2 have worked quite well (despite neither being produced for the Linux platform).
Tip 7 is quite interesting for those who have Razer, Logitech, etc devices and would like GUI support for button and light mapping. One thing where Linux beats Windows though is its built-in support for button and key remapping. It works right out of the box without having to figure out Windows PowerToys.

What’s the Value of 3 Million LPs in a Digital World? Easy! They can be Played still in 50+ Years' Time!
The ARChive of Contemporary Music has one of the largest collections of vinyl records in the world and is in danger of losing its home. Its champions are making a case for the future of physical media.
If someplace like a university starts a digitization program for someone’s papers or recorded work, they might end that work when a grant or allotted funds run out. At that point, George says, you have to worry about not just where that material goes, but also how you might be able to play it in the future.
Vinyl records are likely to always be playable, but as tech companies come and go, access to a lot of digital archives can feel precarious. “We joke with the people at the Internet Archive about who’s going to last longer, and we’re all pretty sure it’s us,” George quips. “If you’ve got a bicycle wheel, a rubber band, a bundle of sewing needles, and a cone of paper, you’ll always be able to play an LP, but you can’t make a chip at home.”
The ARC has given itself until Valentine’s Day to come up with the additional funds it needs for a new space. Though no one has come through yet, the group has solicited everyone from Quincy Jones to Discogs. “There’s interest, but no one’s actually said yes,” George says.
This is also where copyright, which some love to invoke to protect rights, may end up losing us a lot of the music that is created today. Digital needs to be backed up, transformed, replicated elsewhere, etc continuously to protect it. Just look at the flak that Google had around scanning of books. And even Google loses interest at some point, and that repository of creative works is gone in the blink of an eye. Storage space costs money in the long term, whether physical or digital, but I'd venture to say digital can cost more with its required refreshing, transforming to new types of mediums (storage and players), backups, etc.
Digital represents here-and-now convenience, but it is really not an effective long-term archive for mass storage of creative works.
Our generation probably needs to lose a large amount of its memories before the world wakes up to the fact that digital photos, books, music, etc are risky to keep in digital only format for long term archiving. That encrypted hard drive at home sounds like a great thing for its owner to have, but what does it mean to that person's children or grandchildren one day when it is inaccessible and holds the family photos, recipes, scanned documents, etc which can never be accessed by anyone?

The Mystery of the Apple Zero-Day Vulnerability CVE-2023-38606
I just finished listening to the analysis by Steve Gibson in Security Now episode 955, and it is very interesting. No surprises actually at all, but it does put things more in perspective and out in the open. Unless Apple actually spills the beans, which is most certainly not going to happen (and possibly legally they may not be able to anyway), we will not know for sure why this happened.
The technical explanation in the podcast is worth listening as it gives context as to why this was no ordinary accidental vulnerability that was discovered. It also explains quite clearly why this was not a debugging back door as Apple claimed. The very final conclusion is rather chilling, though: A new such vulnerability could be introduced in newer models, and we cannot be certain that there is actually a Plan B and C backdoor that still exists.
The end discussion included a possibility that China and/or Russia may have mandated such a backdoor to be put in place, but they have also started to ban the use of the iPhone by their own officials as far back as two years ago. If this were the case, two other possibilities then exist: Apple as a US company could not be legally mandated not to mention what had happened, and secondly that Apple products are no safer than any Android products and maybe worse off if it were an OEM introducing secure back doors.
Marketing hype about security and privacy seem a bit thin now, given the type of vulnerability this is. In fact, it would have put many other countries and governments at their ease by believing what was being claimed.
Even if the claims about the backdoors being put in place for Russia/China, I'm pretty sure that the US legislation around the Patriot Act and the CLOUD Act would have allowed this to have been kept away from the US NSA. Those Acts place a muzzle over any US owned company too, so that they are not allowed to mention or report any such access.
So, it is all very interesting and the facts are we will probably never know who or why, and we can now safely assume that all mobile devices are insecure by nature and due to their complexity (no surprises). What we don't know, just has not been discovered yet. We also cannot trust any government to not spy on its own citizens, or other governments (including their own allies) - again so surprises at all as we've seen the evidence over the last 10 years of this as well.
But, I did find this analysis very fascinating, as it just demonstrated the depth and extent that these measures actually go to. We live in intriguing times as we have also been learning last year we cannot trust video and images that we see posted online. All this makes the 20th Century censorship, propaganda, and spying look like nursery school stuff. Today's propaganda and spying is extremely technical, and is being performed by nation level actors. Citizens have very little hope of figuring out for themselves what is what with all the deflection going on.

Hacking BLE to Liberate your Exercise Equipment eg for the Domyos EL500 elliptical trainer
It’s a story we’ve heard many times before: if you want to get your data from the Domyos EL500 elliptical trainer, you need to use a proprietary smartphone application that talks to the device over Bluetooth Low-Energy (BLE). To add insult to injury, the only way the software will export your workout information is by producing a JPG image of a graph. This just won’t do, so Juan Carlos Jiménez gives us yet another extensive write-up, which provides an excellent introduction to practical BLE hacking.
Yes, the process may seem like a bit more effort, but it could have three major potential advantages:
* If the supplier decides to no longer support the app or device, or goes out of business, this won't affect the hack.
* It looks like some additional data may even be able to be extracted.
* Your data need not be captured and read by the app any longer, meaning increased privacy.
The project is not yet completed though, as it seems the data capture and analysis is still being worked on. Looks like a project well worth keeping an eye on.
The unpacking and analysis of how the BLE GATT comms works is also very interesting.

ExifTool by Phil Harvey is an open source cross-platform tool for reading, writing and editing image metadata
I was looking for a utility to do a batch run through subdirectories of JPG files I have, and create an XMP sidecar file for each. Exiftool is one of the best tools to do this, and it has been around now for nearly 20 years.
It can do just about any EXIF manipulation you can think of, and is actually used in the background by many other applications, such as digiKam. In fact, you could write your own application in Python, or another language, to manipulate EXIF data with Exiftool.
It is a very powerful way of doing a metadata search through all your digital photos to find photos taken with a specific camera, time of the day, location, or any other metadata saved in the image. For example, say you edited some photos a day or two after you took them, Exiftool can help do a single batch update to change those creation dates back to the original photo dates. Of if your camera's date was incorrect, you could batch update the date of hundreds of photos, or you could strip out the metadata before uploading photos to a social media site. It should be possible, too, to search thousands of your photos for those taken at your home location, and then to strip out the geolocation data.
If the command line seems a bit daunting, there is also an excellent GUI app written in Java called jExifToolGUI that runs across the various desktop OS's too. This post's featured image shows what that application looks like.
Both Exiftool and jExifToolGUI have been receiving regular updates, so are both actively maintained.

Tetris Has Finally Been Beaten After 34 Years
Blue Scuti has cleared that fabled 'final' level and crashed Tetris, beating it after over three decades. Because the game has no story, levels, or any form of progress beyond high scores and increasing speed, you 'beat' the game by crashing it, AKA reaching the "True Killscreen".
Bizarre things started to happen at the highest levels, showing this game was probably never intended to go so high. It's incredible though to see such a classic and simple game having such a cult following, and level of competitiveness for so many years.
The video in the linked article gives a good overview of the history of Tetris high scoring and why it broke through new levels (the speed-up caps at level 29). It shows, too, that you need to shift your paradigm a bit to get different results.
It does seem though that it's not a hard crash and that some variables contribute to when it happens, so it may be possible to push things even a bit further.

Open-Source Desktop Publishing App Scribus Gets Huge Update
When it comes to free, open-source desktop publishing (DTP) there’s little as capable, as fully-featured, or as widely used in professional settings as Scribus.
Now a brand new stable release of this powerful page-making tool is available, the first since 2019.
Scribus 1.6.0 ships with “thousands of enhancements and fixes across all areas of the program”, with its development team noting it’s more featured, faster, and more stable than all versions prior.
Used to create everything from newsletters to books, Scribus provides scores of features commonly found in paid-for, proprietary DTP software, allowing users to design and create complex layouts, manipulate text, insert images, manage colours, and export documents for free.
Interestingly, Scribus is now around 23 years old, so it is a solidly mature product. Yet it can work on macOS Apple Silicon and also has a distro-independent AppImage installation available. It's the perfect tool to design once and use across all desktop OS's.
Scribus has many unexpected touches, such as powerful vector drawing tools, support for a huge number of file types via import/export filters, emulation of colour blindness or the rendering of markup languages like LaTeX or Lilypond inside Scribus.
The Scribus file format is XML-based and open. Unlike proprietary binary file formats, even damaged documents can be recovered with a simple text editor – sometimes a challenging problem with other page layout programs.
Reliable PDF creation is the key to a successful print run at a commercial printing house, and it has been a pillar of Scribus development since the early days of its development. Scribus was the first DTP program in the world that supported the demanding PDF/X-3 specification. Scribus also offers a wide range of options with respect to PDF export.

How to maximize anonymity when accessing the Internet on mobile
Some interesting tips and ideas, but what becomes very clear, is the irony that the ordinary citizen is going to be way more identifiable than most criminals will be. It costs money and/or effort to anonymise your mobile phone usage. And, certainly, if you want to actually connect to mobile networks at all, that blows much of the anonymity you may have been trying to achieve.
The article does give some insight though into what identifies you on the networks. If you don't want to be tracked, the simple advice is, don't carry a phone.
Interesting, too, to read that the mandatory registration on SIM cards has not shown any evidence of actually preventing or solving crime. In South Africa this year, we just heard that the whole system is a shambles, as many SIM numbers get recycled after not being used for a while, and someone else gets the number that was already linked to someone. I made the comment at the time, that this was just inconveniencing law-abiding citizens, whilst criminals were still easily procuring cheap SIM cards on the streets. It seems that most politicians/officials want to be "seen to be doing something" without any interest at all whether it is effective or convenient.

Immich Self-Hosted Photos and Videos Solution - My Warts and All Video Review
Immich is a really modern looking and responsive self-hosted solution for your photos and videos. It has a number of similarities to Google Photos and is often promoted as being the closest alternative right now to Google Photos. I've installed Immich on my VPS, connected it to my 13,000+ Piwigo photos, and been testing it out for the last week.
My review shows what is working well, and what I see as some potential shortfalls (as at Dec 2023) compared to Piwigo and other solutions. Immich is under very active development, so I'm sure some of these issues will be addressed in the coming year.
But if you are considering Immich, and are wondering how it compares to something like Piwigo, this video may be of help to you. Likewise, if you're trying to get Immich to connect to external libraries.

How to turn an old PC into a NAS
A dedicated NAS may be highly functional but they are often pretty pricey... You often also don't get a decent resale value on your recently replaced, but perfectly functional, PC.
There are a few reasons that you may want to use an older PC, but the biggest is simply just the act of recycling. If you have a perfectly good PC lying around not doing anything, why would you go out and buy a NAS instead of just putting your old computer to work? Especially because older computers like those are probably going to be more powerful than most NAS devices that you would pick up, it's really just a no-brainer.
There is also some quite nice 3rd party NAS software to choose from, that also helps make the device quite flexible in terms of functionality.
