jdboyd··on Woodworking for Engineers
Get Hands Dirty https://www.youtube.com/channel/UCETeXD_3awsQv-9rSdCYXQQ

I'm in the US, but I find a tend to like european woodworking channels better.

jdboyd··on Haiku R1/beta2 has been released
Because she really wants something fringe and not really Unix. I'd be surprised if there was any user or developer that didn't do Haiku as a hobby. I've never heard of a single person making money from it.
jdboyd··on Success Stories of Internet of Things
From article: "Coca-Cola was one of the first to introduce IoT to customer service and in 1982 one third of vending machines were connected to the Internet."

That seems really unlikely. Assuming it was a typo, does anyone know what they meant to say, and/or have a source?

jdboyd··on macOS in QEMU in Docker
Only if you do it on a non-Apple comoputer. If you install linux on your mac, then follow the guide I believe it should be fine.
jdboyd··on Building a Gaming PC for 100$: Is It Possible?
It seems likely that Doom Eternal would also run acceptably on that machine, but that CPU generation and GPU are definitely on their way out.
jdboyd··on Building a Gaming PC for 100$: Is It Possible?
I like sff machines like the Dell Optiplex. The problem with them though is the lack of compatible graphics cards.

Email: jdboyd@jdboyd.net

Bio: I am a software engineer with 20 years of experience. I've been contracting for 3 years (usually short term projects for small companies), but finding new projects has been rough for the past 3 months.

jdboyd··on Ask HN: Any resource on how to repair MacBook logic board?
That is what people said, and yet still repair techniques are devised. The cryptographic storage is not tamper proof and thus is all the more reason to repair a board at least well enough to recover your data.
jdboyd··on Ask HN: Any resource on how to repair MacBook logic board?
A number of top apple repair places, like Rossman repair group and iPad rehab, clearly do not use an oscilloscope, logic analyzer, reflow oven, or vacuum chamber on any if the repairs I've seen. You do need a reasonably good soldering iron, hot air tool, multimeter and magnification. The most used tools could probably be assembled in cheaper starter form for $1k, but some repairs would only need a subset of those. And Rossman repair guides will step you through anything that can be done with the smaller art of tools.

I don't know how stay or not your hands are. I've learned that you don't need rock steady hands for most fine hand soldering, but you likely would need them for putting dmm or oscilloscope probes on fine features. I find that good magnification makes it easier to steady my hands.

jdboyd··on RISC OS and NetBSD running on the same SoC
Here is a forum thread on doing this that looks to be from the same guy (based on screen caps included), but gives a little more detail: https://www.riscosopen.org/forum/forums/5/topics/15128
jdboyd··on Ask HN: Where do you find software development freelance work?
For Craigslist list, if it isn't popular in your area, you can use it to search larger cities as well.
jdboyd··on The Qt Company is stopping Qt LTS releases. KDE is going to be fine
Only mentioned in passing, but I think the lack of offline installer will hurt open source users.
jdboyd··on City Roads – Draw all roads in a city at once
It's really simple looking, but I entered my city, and I just love the graphic that was rendered. Is there any chance of making it produce SVGs to download?
jdboyd··on For tech-weary Midwest farmers, 40-year-old tractors now a hot commodity
I think that you would have a hard time getting EPA approval if you starting making brand new copies of legacy engine designs. A new diesel tractor engine has to meet EPA Final Tier 4/ Stage IV standards. I don't know what would stand in the way of making a knock off of the 4440 chassis and transmission that uses a new Cummins or other crate engine though.
jdboyd··on Rhasspy is an open source, fully offline voice assistant toolkit
AES67 microphones exist. Shure, Audio-Technica, and Audix are just 3 manufacturers that make them. Some of them are called Dante mics and you have to turn on AES67 in a confirmation menu. I don't know that there are any good AES67 drivers in stock Debian or Raspbian, but a lot of AES67 devices can be used with any software that supports rtsp. Whether one install of rhasspy can handle multiple streams at once is a different question. Also, even the cheapest AES67 equipment is expensive enough that a new raspberry pi or odroid h2 per room would be cheaper.
jdboyd··on The “mail is hard” myth
In my experience of over 15 years, the "rules" have only changed 3 times since I started. First to require good reverse DNS, then to require SPF, last to require DKIM. The transition on each of those was generally several years with plenty of publicity.
jdboyd··on The Surprising Number of Programmers Who Can’t Program
If they take that shortcut in Python, it tells you that they probably know Python, which also likely suggests they could think it out if they had to. If they think it out the harder way, that shows they can do that, which suggests they can get some things done. It isn't rare to find applicants who have more than 10 years of experience who somehow can't do either.
jdboyd··on People love working remotely
> a 15 minute fact-to-face is better than a multi-day email chain

What if it takes you 4 hours to come up with a good answer?

jdboyd··on A $5,600 Electric Makeover for Old Diesel Cars
I wonder what that £20k would turn in to if you could commit to your suppliers that you would be buying a thousand units worth? What about only 100 units worth?
jdboyd··on How is China able to provide enough food to feed over 1B people?
How does that help? I'm being serious in asking.
jdboyd··on Prime Video on Chromecast and Android TV, YouTube on Fire TV
If you can't find the YouTube for Fire TV app on your device, here is the link on Amazon's website:

jdboyd··on YouTube bans content “showing users how to bypass secure computer systems”
Good luck explaining that to their robots that don't know how to listen and aren't too think logically.
jdboyd··on FreeDOS's Linux Roots
Thanks for posting that. Sounds like SeaBIOS or FreeDOS.
jdboyd··on FreeDOS's Linux Roots
I suspect that when we get computers that are pure EFI and completely free of legacy BIOS, it will be possible to use something like SeaBIOS to continue to add back BIOS compatibility for use with tools like FreeDOS.
jdboyd··on Raspberry Pi 4
I think that aside from versatility and community, the other big thing these have been great at is long term availability. Just look at how many other Pi "killers" have come and gone pretty rapidly, or never ended up getting good OS support.

I will say, I suspect that for a media box, USB3 storage may be good enough.

jdboyd··on “I’m sorry we’ve given the impression that we're dropping support for i386 apps”
It seems impractical to drop support then re-add it. Probably less work to keep building and testing it all along then to have to fix 2 years of 32 bit specific bugs all at once.
jdboyd··on “I’m sorry we’ve given the impression that we're dropping support for i386 apps”
Fwiw, 18.04 is promised security updates until 2028 instead of the normal 2023.
jdboyd··on “I’m sorry we’ve given the impression that we're dropping support for i386 apps”
They will still be shipping 18.04lts, with security updates, for years to come. This will be increasingly outdated. I'd like to hear specific examples of where that would be a problem though, besides Wine. More specifically, I don't understand what Valve is so upset about since Valve already supplies their own run time that games are recommended to use, and I hope that would apply to their photon system.
jdboyd··on What Happens After Amazon’s Domination Is Complete? Its Bookstore Offers Clues
Many other websites are turning themselves into fairly open accrss market places as well, meaning you have to increasingly go through the same steps on them. A few examples: Newegg, Walmart, Lowes. Now, perhaps those 3 examples are better, but they seem to be determined to head the same way as fast as they can.
jdboyd··on Buy a Raspberry Pi 4 Model B
It took a few years for me to accept this, but the ongoing commitment to continuing to make available most Raspberry Pis is a pretty compelling argument for many business purposes over using a random old used PC or a more powerful SBC that may not longer be available in a year. The development of specialized OS distributions for some of these tasks only furthers the strength of the choice for going with what could be otherwise under powered hardware.
