I feel like this is the approach that Mathworks [1] (Matlab/Simulink -> FPGA) and Intel [2] (OpenCL -> FPGA) use. [1] https://www.mathworks.com/solutions/fpga-asic-soc-developmen... [2] https://ww

This was a good episode and really showcased how the standards were forced to evolve by various stakeholders (protestors, execs, govt, etc). I think I recall one them pointing out that a lot of challenges came from Facebook trying to be eve

Getting a license is your first step if you want to transmit. If you are in the US, the ARRL produces the training material for the various tests. There are free apps that go over the test questions but I like having a little more context t

I would love to have an advanced file system that works on portable drives across multiple OSes. ZFS is not designed for this use case, but at least it is something. Having compression, encryption, integrity checking, and data duplication o

Pretty sure some of the Harmonic Drive patents have lapsed. Cone Drive is now making some very similar products.

I use alot (to view and send mail) + notmuch (to index) + mbsync/isync (to retrieve mail). It was painful to configure, mostly due to needing scripts for syncing up tags with IMAP folders. So far its been worth it. Instantaneous search

Some experts believe those bans are an over reaction. The Wikipedia article on the topic is pretty US-centric, but I get the impression allergy rates are lower in other parts of the world. Peanuts are cheap and nutritious. I'm sure tha

While I look forward to a faster desktop and mobile browsing experience with HTTP/2 I do worry about the complexity. I hope that the simpler protocols remain supported for a long time to enable implementations on low resource embedded

Unrelated but this article is a diamond in the rough for hams. I have to applaud the fairly concise writing style and actual use of math. I've recently gotten in to amateur radio and it has been exhausting reading the wordy and anecdot

I would like a "pricing" and a "privacy policy" link on the front page. Probably won't spend time trying it out due to the omission. Luckily there are interesting self-hosted / local options mentioned in this t

Unfortunately not all of us have alternative ISP's to switch to. I hear upgrading to a business account can help with certain providers but that's not always available at all locations.

I understand your criticism but the Columbia Accident Investigation Board released a full report with recommendations for changes 6 months after that accident. Not too shabby. Right now we have a press release that is pretty thin on details

I would also like to be able to receive these stations. Especially when hiking or otherwise in an remote area with no cell service. Minor nitpick, its a narrow band FM signal around 160MHz not AM.

HD Radio really grinds my gears. They hijacked the HD acronym for marketing: it stands for Hybrid Digital. As you mention the quality is not comparable when you have a strong analog FM signal. On top of that the encoding is proprietary and

Instead of hacking think of it from the other side: If no computer connected to the Internet has a reasonable expectation of privacy then law enforcement must develop a system to manage all of their data and IT needs that is not connected t

The Planet Money podcast #677 (The Experiment Experiment) discussed an effort to reproduce some experiments. One of the methods they discussed to both increase reproducibility and reduce experimenter bias was to register the experiment proc

You can get better performance using the proprietary driver because you get access to all the device parameters. Depending on your application this can be critical.

While I don't like that FTDI is pushing their brick-making drivers out over automatic updates, I think the folks calling for everyone to ditch their chips are a little over the top. Personally, I would love to have a reliable way to de

3-6 months is not that bad. Especially if it means you can guarantee that you get genuine parts. Most real projects can easily handle this lead time for production.

"I have worked with a few embedded SDKs (by Microchip, Keil and Espressif), and all of them have a really dumb built-in implementation of the heap." Many embedded systems allocate just once at startup and these "really dumb&q

Just guessing, but I don't think this system controls the robot with the computer. It may command it, but the closed loop control is probably not happening on the Mac. At that point your interfaces have much looser requirements. Th

Not sure SpaceX rockets count as cutting edge technology. They are based on rather mature technology developed by NASA. This does highlight the difficulty of manufacturing a complex system in small quantities without the opportunity to do a

Electric motors do have a constant power region and its ideal to operate there. I would expect teams to modify their transmissions to better fit their motor as more parts of the car are opened up for modification.

Everyone is driving the same car only for the first season. Second season they are opening up the motor and inverter for improvement and modification. In the third it sounds like the battery will be opened up as well. My guess is that they

Very interesting. Will definitely look into this. All of our tests right now are implemented as VHDL/Verilog testbenches. We automate building and running in ISim with a simple Python tool which generates xunit output. It works but its
