I picked up this half keyboard for $30 at an embedded conference in Boston probably 15 years ago. It's amazing how quickly your brain 'gets' it and your typing speed ramps up: https://matias.ca/halfkeyboard/

I'm guessing at some point they got approved as an assistance device, because now they sell for $500. Presumably it's insurance companies that are paying at this rate.

Yes, and a couple of other things- the water acts as an RF ground plane, so different sea states experience this differently; the humidity in the first few inches off the surface is enough to affect signal performance; and mist and spray from splashing affects things more.

The ocean's a big place, and really hard to operate in. I'm looking forward to seeing how low power the terminals end up consuming!

I'm reminded of an old mentor's saying: One is an anomaly, two is a coincidence, three is a pattern. I'd be interested to know the causes and the effects of the temperature rise that makes you think this one is no big deal. There is a lot of evidence to indicate it's a very big deal.

Characterizing the effect of near-surface humidity and wave action on Ka/Ku band satellite transmissions from a surfboard-sized autonomous swimming vessel. I have a little sensor platform, and customers that want it to do a whole lot more. Bandwidth can be hard to come by 6000 miles from the nearest human.

Also, working on how to integrate a small team of hackers into a big team of production oriented engineers. Making the first of something is such a different skill set to making thousands more.

I got here by getting headhunted for a neat-sounding job after a project elsewhere ended, and then assuming more and more duties until my title had to change to match my responsibilities.

"not unusual" is a little facetious, don't you think? Vinther was studying a drastic loss of polar ice in reaction to a historical (unexplained?) sudden rise in temperature, and raising an alarm in light of our current warming.

From NOAA:

"In the 200-plus years since the industrial revolution began, the concentration of carbon dioxide (CO2) in the atmosphere has increased due to humans burning fossil fuels (such as car emissions) and changing the way land is used (such as deforestation). During this time, the pH of surface ocean waters has fallen by 0.1 pH units. The pH scale, like the Richter scale, is logarithmic, so this change represents approximately a 30 percent increase in acidity."

This was 14.04 as well, on a Tegra (armhf) system.

eta: looked up the ticket, customer reported "when trying to delete any files, even as root, btrfs says "cannot remove"", field engineering observed the same.

Good trick, I'll save that one. Thanks!

I've had one issue with btrfs that took it off my radar completely. A customer had a runaway issue that filled a btrfs device with unimportant things. We found the errant process and killed it, but apparently if a btrfs device is completely full, you can't delete anything to free up space. File removal requires some amount of free space. Bricked the device, annoyed a customer, back to ext4.

That makes sense, good luck with it!

Interesting idea! The name is a little hard to take seriously with the misspelling.

Some of the reviews are very detailed with expected salary ranges and career progressions, and others are really sparse- the Sales Engineer for example, or the Flight Nurse which is basically an anecdote that tells you nothing about the field, how to get into it or what it's like. I'd have a template or guidelines for your reviewers, and reject anything that doesn't match the quality of, for example, the Investment Banking VP or the Crane Operator.

Liquid Robotics | Sr. Software, Sr. Systems, Systems, Manufacturing | Onsite | Full Time | U.S. only

Liquid Robotics builds autonomous, wave- and solar- powered maritime sensor vehicles that return real-time data from the open ocean to customers on shore. We have nearly 500 vehicles out in the world working in science, oil and gas, and defense. Work is located at our engineering office in Sunnyvale, CA and our field test facility in Kawaihae, HI.

Core vehicle and shoreside software is Java, sensor payload software is in Java, C, Python, Lua and anything else that's appropriate. The newest vehicle uses an Nvidia Tegra running linux. Multi-discipline engineers are encouraged- my 4th day as a software engineer 5 years ago I had to go buy some tools and a butane-powered soldering iron. More info at https://www.liquid-robotics.com/

I work around RF sources professionally. I'm intensely interested in any biological effect of the radiation I work around. I have access to journals through work and my old university, and I read primary sources with great interest (and some knowledge, being an electrical engineer). I have yet to find any credible link between gigahertz RF and health problems (except the neck problems that come from staring at a phone).

I feel like the most damning lack of evidence is the lack of correlation between cell phone adoption and the purported ill effects. In the last 20 years pretty much the whole world started holding RF transmitters up to their head, from basically zero beforehand. If there was an effect, it would be epidemic.

Only a third of Americans -have- a 401k, and only 13% have pensions.

Liquid Robotics creates autonomous wave-powered ocean vehicles- remote sensor platforms that are used in oceanography, oil and gas, defense and communications. The platform doesn't require fuel for propulsion, and can operate for up to a year in the ocean which creates unique engineering challenges for durability, fault tolerance and remote sensing. Engineering happens in Sunnyvale, field testing at our Big Island field site. We're building out some new project teams and some new capabilities.

If you're in Las Vegas, the National Atomic Testing Museum is very worth a visit. The last time I was there they had a traveling exhibit of Soviet nuclear propaganda that was fascinating, and there's a lot of info on Trinity and other testing sites. I found the quality of the exhibits to be very high.

I liked it for the perspective of someone who grew up here, went to Silicon Valley elementary and high schools, saw the toll the culture took on her peers. Then left for college and came back for work. I think that perspective: "I should love this place, it's home, but damn is it broken" is valuable. Maybe more for me than you- I'm raising 2 daughters here.

Do you have any examples of such negative consequences, regulations for problems that went away (that became inconvenient after the fact), or dangerous and abusive regulations? Your objection sounds dogmatic, but if it's founded I'd love to hear on what.

I think educational standards are saying this: To be a functional member of our society, you need to be well grounded in certain subjects. Reading, arithmetic, basic chemistry, basic physics, basic biology, history (local, your country, and global), economics (personal and global), classic and world literature, and so on. Many subjects you may not find on your own. An elementary education seeks to expose you to an overview of human knowledge so you can, if you choose, pursue the bits that interest you further. It also seeks to give you the foundational skills to operate in the society we've created.

I mostly object to homeschooling, charter schooling, unlearning and anything else that takes children out of their community and away from community standards of education. I understand some people object to their local school systems; I think it would be more beneficial for everyone if they put their work into improving them instead of opting out of them.

The "Paper Feed" section has 2 articles from 2018 and 2 from 2017. The most recent, "20 Years of Escaping the Java Sandbox" [1] is exactly what 16 year old me loved about phrack back in the day.

400k doesn't sound so rare. The entire population of Tulsa OK, Wichita KS, or New Orleans, LA just drops dead every year?

I do. It's a good way to set expectations, see if they've gotten any interesting recommendations from coworkers, and see if we know anyone in common.

The concern, as expressed by the FCC, is that the satellites are so small they are hard for U.S. Space Command to track them. Which means we could approve a rocket launch where one of these rapid little beasties knocks out a window or causes other catastrophic damage because we didn't know where it was precisely.

And you could argue it's too small to do damage (not true) or to low to be a real concern (maybe true), but the precedent is dangerous to allow.

46 here, well employed and not worried. There are a lot of positions in Silicon Valley for older engineers. On the bias- most of the engineers who are my peers are men. The female engineers I've worked with in my 15 years in California have mostly been in project management, product management and test. Over 40 you may not get hired by any underfunded startups, but the 'old money' is still here and values experience over alma mater and 'dumb enough to work cheap'.

Where do you live? I've never had a bad experience with Kaiser in northern CA. Both of my children cost me $250 total for their entire pre-natal care and birth, all preventative care is free of co-pays, any time I call for an appointment there are multiple slots that day or in the next 3, prescriptions are filled in the in-clinic pharmacy or mailed to you if you prefer, consultancy can happen by phone, e-mail or in person... it seems way better than any other insurance I've had.

The first few are. If you can't pass them, you don't get to waste anybody else's time.

Unfortunately the CS trivia is necessary. In a previous job I interviewed people who snuck past the phone screen and would have wasted a ton of interviewer time if some CS-101 questions hadn't exposed near total ignorance of the highlights on their resume. My favorite was the guy who applied for a job as an air traffic routing researcher and after 20 minutes of computational geometry questions said, "Wow, tough, do you do a lot of math here?" Yeah dude. This is NASA. We do a lot of math here.

Same story here. I never would have known about my company if their internal recruiter hadn't reached out to me on LinkedIn. I blew him off the first time he reached out, saying 'not now, check back next year' and when he called a year later I was ready for a move.

So I still won't be able to see my kids awake because of a 1.5 hour commute each way, but I'll be able to read the newspaper on the way to work? No thanks.
