  • Worth noting is that “good” database design evolved over time (https://en.wikipedia.org/wiki/Database_normalization). If anything was setup pre-1970s, they wouldn’t have even had the conception of the normal forms used to cut down on data duplication. And even after they were defined, it would have been quite a while before the concepts trickled down from acedmemia to the engineers actually setting up the databases in production.

    On top of that, name to SSN is a many-to-many relationship - a single person can legally change their name, and may have to apply for a new SSN (e.g. in the case of identity theft). So even in a well normalized database, when you query the data in a “useful” form (e.g. results include name and SSN), it’s probably going to appear as if there are multiple people using the same SSN, as well as multiple SSNs assigned to the same person.





  • I’ve personally lived in places where the closest convenience store was 2.25 km, and the grocery store was nearly 18km, as well as places where a convenience store was literally a part of my building, and grocery stores were walkable distances.

    The U.S. is enormous and varied. Take a look at truesizeof and compare the U.S. and Europe (don’t forget to add Alaska and Hawaii - they won’t be included in the contiguous states). Consider how different London is from rural Romania.


  • This ignores the first part of my response - if I, as a legitimate user, might get caught up in one of these trees, either by mistakenly approving a bot, or approving a user who approves a bot, and I risk losing my account if this happens, what is my incentive to approve anyone?

    Additionally, let’s assume I’m a really dumb bot creator, and I keep all of my bots in the same tree. I don’t bother to maintain a few legitimate accounts, and I don’t bother to have random users approve some of the bots. If my entire tree gets nuked, it’s still only a few weeks until I’m back at full force.

    With a very slightly smarter bot creator, you also won’t have a nice tree:

    As a new user looking for an approver, how do I know I’m not requesting (or otherwise getting) approved by a bot? To appear legitimate, they would be incentivized to approve legitimate users, in addition to bots.

    A reasonably intelligent bot creator would have several accounts they directly control and use legitimately (this keeps their foot in the door), would mix reaching out to random users for approval with having bots approve bots, and would approve legitimate users in addition to bots. The tree ends up as much more of a tangled graph.

  • I think this would be too limiting for humans, and not effective for bots.

    As a human, unless you know the person in real life, what’s the incentive to approve them, if there’s a chance you could be banned for their bad behavior?

    As a bot creator, you can still achieve exponential growth - every time you create a new bot, you have a new approver, so you go from 1 -> 2 -> 4 -> 8. Even if, on average, you had to wait a week between approvals, in 25 weeks (less that half a year), you could have over 33 million accounts. Even if you play it safe, and don’t generate/approve the maximal accounts every week, you’d still have hundreds of thousands to millions in a matter of weeks.


  • Are they Bluetooth headphones? If so, check the protocols supported by your phone, and by the headphones, e.g. aptX vs LDAC vs SBC. It’s possible that it’s not a “downgrade” on the new phone, but rather an upgrade to a better protocol, but unfortunately not one compatible with your headphones, so you end up using a low quality fallback.

    You may also want to check your settings, and see if you can select a specific protocol. Sometimes a lesser protocol is chosen by default, if the better protocol uses more battery. This may be available to you in the phone settings, or as an option in an app for the headphones (e.g. my Anker Soundcore app allows choosing between two protocols).



  • My first thought was similar - there might be some hardware acceleration happening for the jpgs that isn’t for the other formats, resulting in a CPU bottleneck. A modern harddrive over USB3.0 should be capable of hundreds of megabits to several gigabits per second. It seems unlikely that’s your bottleneck (though you can feel free to share stats and correct the assumption if this is incorrect - if your pngs are in the 40 megabyte range, your 3.5 per second would be pretty taxing).

    If you are seeing only 1 CPU core at 100%, perhaps you could split the video clip, and process multiple clips in parallel?



  • “Desktop publishing” is the category of software you want. I’ve not used it, but I believe Scribus is the standard FOSS tool for this. If you want a simple graphical way to make your album, this is the way.

    Many people have metnioned LaTex - I would not recommend it for this purpose. LaTex, while powerful, will have a steep learning curve, and isn’t really made for artistic tasks - its purpose is for writing technical papers. From literally the first two sentences on the project site:

    LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents.

    It’s probably possible to make a beautiful photo album with LaTex, but without a lot of work, it’s more likely to come out looking like a calculator manual.


  • Considering that you are not using their software, was the laptop worth the premium you paid for it, vs buying from Clevo directly?

    I figured the hardware and software coming from the same vendor would yield the best results, and wanted to support a company that supports right-to-repair, and Linux in general. But ultimately I found Pop!_OS buggy and had performance issues, so I’m not using their OS, and their firmware is causing issues with my SSD, so I’d like to be off of it as well (but was told "there’s no process for reverting to the proprietary firmware“ for the specific model I have). I could have bought a Clevo directly, saving hundreds of dollars, and probably had a better working machine.

    Would not recommend System76. I’ve had many issues with my machine (primarily software, related to their buggy custom firmware, and Pop!_OS, until I ditched that for stock Ubuntu). Their support has been terrible - rather similar to OP’s, actually. I’ve had the laptop for about 2.5 years, and I’m checking practically daily for something to replace it.



  • My usb-c ports can be a little touchy, too. The SD card slot is also really bad - the card has to be positioned perfectly to slide in, or it jams. I’m also upset that the usb-c port can only be used for charging after a full boot. It cannot be used to perform firmware updates, or even to do a ram test. This means day-to-day, usb-c can be used, but I have to keep track of the barrel charger, just in case. This, of course, was not specified on the product details page (nor, I think, that only one of the two usb-c ports could be used for charging - it’s possible I overlooked that, but still frustrating on an expensive laptop that lists usb-c charging as a feature).

    I currently have a System76 laptop, and sincerely regret my purchase. When I purchased it, the Framework was not out yet - I wanted to support a company that supports right-to-repair, and figured since they controlled the hardware, firmware, and software (Pop!_OS), it would be a good, stable experience. It has not been, and support has generally been poor. I know other people have had better experiences than I have, but personally, I won’t be buying from them again.

    I haven’t personally used Purism, but former co-workers spoke really poorly of them. They were trying to buy a big batch for work, and said the build quality was awful. Additionally: https://youtu.be/wKegmu0V75s

    The battery life and speakers will certainly be model dependent. The quality of the machine I received and the lackluster support, given the price I paid, are what I find most frustrating. The computer would be fine for ~$600, but I paid over $1000. I paid a premium expecting System76 to hold themselves to a high standard, and so far, they’ve let me down in multiple ways.

    I do recognize with a different model, the experience could be 180°, but if buying from them is a roll-of-the-dice, for me personally, that’s enough to buy from someone else next time.
