Which of theirs is the most comparible to the flipper zero? Besides the cool looking Cardputer it is quite hard to make sense of their product lineup and compare features.
That case is even worse as it rested fully on the testimony of the other robber, which he made to get a lesser sentence and later rescinded:
> Prosecutors had no forensic evidence connecting Allah to the shooting. Surveillance footage at the store showed two masked men with guns, but they were not identifiable.
The state’s case rested on testimony from Allah’s friend and co-defendant, Steven Golden, who was also charged in the robbery and murder. As their joint trial was beginning, Golden pleaded guilty to murder, armed robbery and criminal conspiracy and agreed to testify against Allah. Golden, who was 18 at the time of the robbery, said Allah shot Graves.
> Golden said he agreed to plead guilty and testify when prosecutors assured him he would not face the death penalty or a life sentence – a deal that was not disclosed to the jury.
> “I substituted [Allah] for the person who was really with me,” he wrote, saying he concealed the identity of the “real shooter” out of fear that “his associates might kill me”. He did not identify this person.
If your friend is wrongly facing the death penalty and you know they’re innocent there’s no reason to not name the person you claim is the real shooter.
I run my own nextcloud server now for over 5 years. There are some frustrations like the photo app which is uselessly slow.
But for the files sync, contacts/calendar and some other apps it works well.
It _does_ offer a million different things and some of those are half baked but the core functionality (a dropbox-like file storage) is decent in my experience.
Updates have never been an issue. And honestly I am always a bit surprised by that. I don’t update to a new version right away but when I’m ready, I change the version in the docker compose, pull, re-up the container. It performs the database migration and brings up everything.
Never had an issue after using it for years. Not sure what your exact setup is, but it’s certainly not a nightmare to use.
The file syncing is not very good either. It's based off WebDAV and very slow. If you only have a few files it's workable, but it isn't competitive with Dropbox, SyncThing or any of the popular alternatives.
I've noticed issue with older hardware. After a recent upgrade to modern hardware (LAN based), all performance issues have been resolved. Currently serving to >30 devices, including 4K media to multiple endpoints and 100Ks files.
It is also workable if you have more than just a few files. I sync several GB of data, books, papers, notes, photos, videos, etc. Constantly changing and it has been pretty fast. Webdav is just the interface used for external services that support the protocol. Which may not be the best tech but it certainly is supported by many, many apps and services. I cannot connect a random e.g. pdf reading app with Syncthing and maybe not with Nextcloud directly but certainly via webdav.
That microscope is amazing. Commenters debate whether it costs 30k or more around 100k so it is further out of reach for most hobbyist.
A few years ago I had quite a lot of fun with one of those cheap $30 wireless USB microscopes with up to 1000x magnification that connects to some app. My family and I always came up with new ideas about what we should look at next. Incredible fun. Unfortunately it broke down rather quickly. But it opened up the world much more than traditional backlight microscopes I am used to. They are basically “just” specialized cameras with bright flash lights.
I wonder if prices have come down a bit and if there are good options out there for such a portable microscope that doesn’t break so quickly. Better quality and magnification in the $200 range?
I believe that's a Keyence microscope, and yes, way outside the scope of a hobbyist! They have a range of microscopes for this kind of thing. Some are also able to perform accurate dimensional measurements (sort of like the old optical comparators machinists used to use but far better). They're typically used for incoming inspection in manufacturing processes.
I bought this microscope that has HDMI port for connecting monitor. Cost me little over 100€. Has no lag. Quality worse than what in video but better than some I see on youtube that also lags. This microscope is not perfect but capable to do smd soldering.
I am using 1500€ Amscope for soldering tasks. It does not have such amazing magnification. Such magnification is also not needed for daily work. But it replaced 10k Olympus device from a decade ago. Optical devices got radically cheaper in last 20 years. SMD rework is not possible without them.
Such amazing scope is built in into 70k professional SMD rework station I use sometimes for complex repairs. Replacing RAM and processor chips is easy, but slow. Honestly I don’t think, that the scope in video is extraordinary expensive. Definitively cheaper than my old Olympus gear.
I bought one of those pore cleaners when I had some pores and quickly realized it was a microscope camera basically, so removed the pore thingy tip and started using it as such (which seems to be the same as you from the description). It was so interesting to explore all sort of stuff! From checking a small cut I got in my head, moles and other parts of my skin, to electronics, different kinds of fabrics, woods, etc.
Wait so the people were pulled into the magnetic field? Were they wearing ferromagnetic metal items that were pulled in? And what does that have to do with the vest that the patient is wearing? If that is ferromagnetic, would that not just simply be stuck inside the MRI?
The nurse was wearing a weighted vest. Presumably the weights were metal of some sort. I can only imagine the sort of metal gear the security guards were wearing. Those guys love dangling stuff from their belt.
To me there are either two ways: when you are trying to learn the thing XYZ you are seeking, drill down to the first thing you don’t understand and consult a lower level resource. Continue until you reach a level you understand.
And the second way is: Re-learning “all” of essential math and then going back to XYZ.
I don’t think the second step is feasible, as you cannot possibly learn everything in a breadth-first kind of way until you are deep enough to learn the (now level-adjacent) topic XYZ.
But for strategy 1, the question is 1) how to identify the problem that you are lacking (e.g. how to isolate math gibberish into a concrete concept) and 2) how to find a good resource to learn and practice this concept at this level?
I do struggle with this and sometimes randomly learn some lower concept again but notice later it did not help me in the end and just left me with a million untied knots that were infeasible for me to entangle.
What I like for USB-C cables is not only a tester that tests how much power it can transmit but also what data rates. I wish I could get a device where I could plug in all my cables and it would rate them for me. Such a device probably exists and it probably costs thousands of dollars.
You might be able to get partway there by setting up thunderbolt networking between two endpoints. The caveat is that USB 4.x is still new enough it may require a significant time sink to get working at ~40Gbps et al, so your testing wouldn't be able to scale that high. But you can go to 10Gbps without too much effort: https://news.ycombinator.com/item?id=39003469
USB is quite the rabbithole, with a lot of functionality often hidden: https://news.ycombinator.com/item?id=39470381 - my takeaway from this is that "the PHY in the controller is 99% of the SERDES you wish you had, you just have to figure out how to make it cooperate"
The chipsets found attached to ARM devices and SoCs etc may be easier to poke around at, but they are likely to either be expensive or just USB 3.0. :)
Then there are devices like the FNB58 and the Power-Z KM003C that interrogate the controller chip in the cable and tell what charging protocols the cable supports, and also measure practical charging voltage and current (and you can acid test chargers using USB charger dummy loads). These devices don't test the cable's speed though. (On that note, https://old.reddit.com/r/UsbCHardware/comments/1b5wgc6/how_t... - that subreddit may also be interesting)
Would plugging in your fastest external SSD and then using a hard drive read/write tester achieve some of the same ends? I've done that before with Blackmagic's disk speed test app and found it useful
Here is hope that they will add a motherboard with the new Qualcomm arm chips in the future. Although I can already see that the whole architecture may be too different to make it fit?
