Check out my site: https://ShieldDigitalDesign.com I put blog posts there, and there's a small but growing hardware design knowledge base as well (at https://wiki.ShieldDigitalDesign.com).

Additionally, feel free to contact me any time, I love chatting about hardware, signal/power integrity, and high-speed digital design.

The subheading to this article seems a little extreme: "To fill the talent gap, CS majors could be taught to design hardware, and the EE curriculum could be adapted or even shortened."

The article is more in the area of chip design and verification than PCB hardware, so I kinda understand where it's coming from.

`sl` is my favorite first package to install in any distro to get see if the package manager works :)

I put together some of my thoughts on the latest generation of AI tools. Whether you love to use these tools, or actively avoid them, nearly everyone is most certainly intrigued by them. Personally, I'm super conflicted. I've seen some really awesome ways they have been a help, but I'm honestly a bit worried about the society-wide impacts they may have.

Same here. I spent a good chunk of the evening just today messing around with Steam to see what I could get running on Linux. It's been a while since I tried in earnest, but I got all the games I wanted running (minus VR, but that felt like it was close). Even though I barely play any games anymore, it's the last reason I haven't wiped my Win10 drive.

Wow, the web version is neat in its simplicity! Thank you for the work on Solvespace. It's far and away my favorite MCAD program and always my first go-to when I need to crank out a quick fixture to test PCBs. It's really so pleasant and easy to work with as long as my geometry is relatively basic (which it almost always is given my limited scope of work with mechanical design). I'm sorry I don't have any comments on the relevant topic of the fonts, just was excited to see Solvespace mentioned.

I think this was already discussed recently, but I find this quote in the article very interesting:

"Passengers don't listen, a lot of them think the TSA is a joke. The fines are a way to enforce the rules for the REAL ID," the former TSA officer told TheTravel.

I've got one very concrete reason why I do think the TSA is a joke. They list a Veterans Affairs health ID card as valid ID even after this new Real ID rule. Despite that, I was forced to go thru "extra screening" in Austin because a bunch of agents were not aware of this (even though I had a print out of the website). Even in the TSA press release announcing this new fee still lists the VA ID as sufficient, but I'll forever just recall the complete lack of professionalism and knowledge of these agents.

As I looked at the chart my first thought was regarding how many women were working a few decades ago compared to now. It's nice to see that the comments below the chart pointed out the same thing. One of the saddest things about today's society is how many 2nd parents are forced to work even when they would prefer not to.

Thank you so much for sharing this! My kids all play instruments and I'm a bit jealous of their skill (I never played anything growing up). Over the last few weeks I've taken to borrowing my son's guitar at night and working through one of his books. I've been looking for more information on music theory, and this is so perfect. I'm excited to go through it. Thanks again!

I had a similar pleasant experience with Skype. Back in 2009, I was deployed to the Persian Gulf. This was before ubiquitous cell phones (at least, I left my cell phone back in the US). Phone cards worked to call home, but my cheap solution was to use Skype from my handheld PSP using Wi-Fi from a cafe. It worked out great for me at least, and I'll always appreciate that.

Skimming the map, I see many listed are in parking lots for Home Depot and Lowe's. I assume that's because of high dollar items and common theft issues? I'm wondering if those cameras are specifically operated by this Flock company, or others as well.

That was a neat video, I wasn't aware of the FX architecture in that detail. I loved my FX series... I had a 6300 that got me through engineering school, and now the same basic desktop serves as my kids' gaming computer (though I was able to upgrade to a cheap 8350). It definitely still holds it's own with the older games that I let the kids play!

You exactly describe my journey! After undergrad, I went right to industry doing hardware design. Given a complex PCB, I was confronted with this field of signal integrity and I fell in love with it. My undergrad didn't explicitly require EM courses, but I learned on the job (lots of reading plus guidance from some experienced RF engineers). Eventually I went back for my master's, and it was so nice knowing exactly which niche I wanted to focus on (and finally get a ton of EM fundamentals under my belt). It truly feels like EE is an infinite field with no limit to the possible type of work...

Haha yeah, last year I replaced my wheel bearings in my van. I ended up with a frustrating ABS code (long story short: faulty magnetic encoders on both of the new bearings). I ended up spending about the same as the job would have cost at a shop, but with a slew of new tools.

I also did a USB switch project for fun, and ended up spending probably $250 for something I could have just bought for $15, but it was a great experience. (Here if anyone is interested: https://shielddigitaldesign.com/posts/2021/susb/ )

"Balking at the $50+ charge for turnkey assembly, I opted to take the financially responsible route and pay $200+ for a hot-air rework station to solder it myself."

Yeah, I feel this :)

Came here to check if this was the case, I'm seeing issues on the Android application. Thank you for confirming that it's not just me!

The other day, I was just remarking how my minivan makes a better pickup than most pickups for most tasks. For years I've wanted to get another truck (had an old Dakota that I had to sell when kid #3 was on the way). Practicality reigns, though, and I'm extremely satisfied with the usability of the van.
