fswd··on A 165-Mile Drone Superhighway Will Soon Be Built in the UK
... obviously then a floating canal train, would beat both of them. The best of both worlds!
fswd··on Teams is killing my Mac every day
I remember... I had half dozen chat clients open, 100+ open tabs in Mozilla Phoenix browser, editors with large projects open for weeks,... compiling, building kernels, running SQL servers, running multiple window VMs, ... all with 100-200 day uptimes. This was back in 2004-2006. AMD Athlon 64, RHEL 3. 512mb of ram... dual 19" LCD displays.

fswd··on Satellites can now find the sources of methane leaks
On a different subject... So Windy.com recently added some more data (click Additional Data/More Data on the side)

One of them is CO2.

In my heavily forested area it reads 79 PPBV. I'm confused because I've always thought we're in the 300-400 PPM for CO2. But if I got this right, 79 PPBV converted to ppm is .079ppm CO2... No? I was expecting a higher number. Something wrong about the V here in the number, volumetric meter I am assuming?

if you click around in the metro areas around the country it does read what I think is 200-400ppbv as expected.

Maybe somebody here can explain: What's the difference between ppbv and ppm?

fswd··on Tell HN: I DDoSed myself using CloudFront and Lambda Edge and got a $4.5k bill
Last weekend I went on a code marathon doing a bunch of CDK AWS stuff.

Soon as I saw this headline, I was completely shocked and dropped everything to check my usage. Luckily I had 'cdk destroy' the big projects, but I had dozens and dozens of lambda and S3 buckets it failed to clean up. I spent probably 1 hour clicking through the web interface deleting them in fear of what happen to OP

I think I'll just stick to LocalStack and VPS.... actually my datacenter friend said I could bring up my deep learning station to this DC might just abandon AWS idea.

fswd··on Alzheimer’s amyloid hypothesis ‘cabal’ thwarted progress toward a cure (2019)
I will take a really risky guess on the premise that there are many different types of causes for Alzheimer's. But one type of them might be caused by parasites. And it's either the body's response or an intended affect of the parasite to enclose the parasite in a type of plague. Kind of like biofilm... or both. Reducing the plague or biofilm could allow the immune system to respond to it by "seeing" it... in some cases. It might also allow the parasite to grow faster if the immune system isn't successful or can't see it. Based on my guess, a treatment plan would involve biofilm/plague "breakers", fasting or behavior changes to reduce and eliminate parasite's life cycle, and anti-parasite medicines that can reach the blood brain barrier. Again, I think there are different types of causes for Alzheimer and this is just one cause.
fswd··on GitHub Copilot is generally available
Anyone know where I can find the source code for the extension itself? Thanks
fswd··on Ask HN: Is there a TV on the market without “Smart TV” features?
Already happening. I bought a new excavator, and it has hidden GPS/LTE modem in it. The only way I knew is that the dealer told me to disconnect the battery when parking it, or it'll eventually drain due to the modem. Of course, they only told me after I bought it. It's the new norm. I guess if I miss a payment they'll remotely shut it off?

fswd··on Code quality only matters in context (2019)
I accidentally discovered something similar 10 years ago in my coding. At one point I had crippling procrastination. My mind was protesting me. New frameworks, languages, etc were just becoming "how many nuances can I remember", and I wasn't learning or going anywhere.

To get over the procrastination I would set up a Pomodoro timer and set it to 20 minutes, and just write something, any code. I made it a joke to write the crappiest code I could, to make it fun, as long as it works. Inline copy pasta, etc. Later on it turned into the goal of the most understandable code, over everything. I would never have done this out of the university, but this was 10 year later. Before I would come up with a "plan" or "design", but at that point, I would just hack something up.

What I found was with starting with an excellent blank CI/CD project, and a good BDD end-to-end testing strategy, I could write "dirty code first" to "just get it done" ... then once I got into a OODA loop, refactor it into amazing products and services while having fun. This reduced my cognitive load and emotional overhead. Coding is actually 5% of the work, the rest is QA, requirements gathering, meetings, UX/UI designs, and overhead.

fswd··on Ask HN: What developer tools would you like to see?
An open source, downloadable and fine-tunable github copilot openai codex model that I can use locally and offline, if I wanted to.

So far I can't rely on copilot because at any time for any reason they can cut off access or change the functionality. Also, the waitlist.

A requirement of the GPL is that they are supposed to release the model but so far I have been unable to find it. There's some kind of "debate" about this but the GPL is absolutely clear in this regard. I'm confused.

copilot is awesome for (lazy) senior devs who want the no-code experience, meaning not having to look up easily forgettable things. How many times have you've forgotten RegEx or how to check for a file exists in bash? Simple put "#Check if file 'filename.txt' exists if not error" and it will complete the bash line. Convert dates in javascript without going to the mdn docs, etc.

fswd··on Show HN: Remult – a CRUD framework for full-stack TypeScript
agree. "inversion of control" doesn't work well for the backend. Had an issue with the frontend due to what I thought was CORS. Putting a simple 'console.log' in nestjs doesn't work... had to write an 'inversion of control' custom logger to find out it wasn't a CORS error but double slashes '//auth/me' vs /auth/me because of environmental variable. A simple console.log could have fixed this but instead it took several hours of research. Really? Why? makess me think nestjs is built for billable hours and frustration... Asking for help you get treated like a jr developer.
fswd··on Deno.js in production
node.js nowadays is a total disaster. I've been able to hold down the fort with turbo repo, but even then it's been a touchy strategy. I want to switch to Deno, and I'm interested in articles like this. Either that, or, because of the state of nodejs/NPM modules, and it's ever-increasing surface area of doom and resume driven development node modules, either somehow switch to deno or go back to just HTML and vanilla js. I just can't get any work done. I'm saying this as a developer with 27 years experience and who has written my own server side spidermonkey solution pre-nodejs.
fswd··on Writing HTML sucks and No-code doesn't help
remix.run, a replacement for next.js, is react framework with vannilla js like abilities, a simple and powerful CSS setup (that makes sense!), a "just html5" escape hatch (or html5 first and react second), and official tailswind support.

It's almost exactly what the author is describing to want!

fswd··on Endemic Pathogens Are Making You Crazy and Then Killing You
my doctor and I had a recent discussion about exactly this. Just incredibly bizarre behavior from people with no explanation. I asked if it could be caused by parasites. She brought up a study in LA where they tested the homeless for Babesia, and many people tested positive. Sorry I did not get the link for this study, but it is plausible. I'm not even sure how we can as a society even address this. One of the treatments is now so politically polarized during the pandemic, even mentioning it out loud is a conversation killer.
fswd··on Dude, where's my fuel?
The theranos vibes you're feeling I believe is from a "flaw" they make an assumption solar is 1 or 2 cents a kilowatt-hour. This isn't true (maybe with subsidies IDK) but it costs more to ship solar panels, and the wiring, fuses, breaker box, charge controller, adds a huge significant cost. You can't just take a panel cost and divide it by the watts without this in consideration. And the land cost. And unless you live in Arizona you will have very low utilization.

BUT... when I lived on the grid I paid $.13/kwh. At 77kwh per gallon that puts us at $10.01/gallon. It is unknown if this is just syn gas or ethanol, or what the BTU of that gallon is. And this definitely isn't diesel, which would have the biggest impact. I know when my friend did bitcoin mining he was able to get $.03kwh so... let's use that 77 * .03 = $2.31. So between $10 and $3 a gallon is actually possible.

With gas over $5 or $6 (the company is in Santa Cruz? Their gas is probably $7 or $8 at this moment, I bet) ... this will work

The other issues are... United States uses 30TW of oil a day (convert barrels of oil to BTU and convert BTU to watt hours... to convert oil used per day in watts to speak of)... and 10TW of electricity a day.

To replace 'fossil' fuels we'd need ...70TW of electricity after inefficiency conversion.

There isn't enough copper, nickle, and silver to make all those solar panels. There isn't enough public support or political capital to build nuclear reactors either. This is another flaw.

Another commentor suggested, just replacing Russian's oil at 4 million barrels a day. That's possible. And it makes it exciting.

fswd··on Preventing Burnout: A Manager's Toolkit
I've had pretty bad burnout earlier in my career and this is what I am doing now

* Better frameworks. If a framework adds complexity, it needs to enhance the feature set and developer experience by 2x. Otherwise, I just stick with the basics. Example: I was working on a react codebase with insane level of hooks, contexts, 7 layers of abstraction. Solution: Axios/Fetch right next to the form, entire backend functions in the controller: no f's given.

* Business requirements first: I hack off 90% of Agile methodology and just do what makes sense. Which is a balance of acceptance criteria and user stories, or contract driven development to pull the features into production and deliver.

* Thursday and Fridays I don't work, and if it do, it's on something completely new or exciting. Last week I played with DallE as an API. Unfortunately this means less pay.

* In the winter if its sunny out, I leave around 2pm. And come back and work 7pm-10pm.

* One meeting a day, or every other day. And Monday's meeting I come in fresh and excited, cite what I am grateful for, and talk about how incredible everyone's effort is. It can sound cheesey but it works for me.

Last burn out was right before the pandemic. I took a position at a startup that told me they were light on meetings, but I ended up spending all of my time in meetings and getting absolutely nothing done. So I left, and took a big break. I forgot a lot of things but realized what I forgot were skills didn't matter. Attitude matters over skill. I am not interested at all in React 18 and instead focusing on Vanilla JS, HTML5, just regular CSS, and just SQL. Day in day out skills. Stuff that won't change in 10 years. If I forget something like a new feature in React 18, then my mind is telling me it is useless in the long term.

fswd··on Potential Gains in Life Expectancy Associated with Diabetes Treatment Goals [pdf]
only one mention of metformin, and it's a title to a paper in the references. however, diabetics who take metformin live longer than diabetics who didn't and nondiabetics in general. the paper didn't take that in consideration that some of the people could be on this seemingly diabetic drug

fswd··on Stabilization of gamma sulfur enables 4000 cycle Li-S batteries [pdf]
You might be surprised researching the current product offerings. Google "server rack battery". I am off grid with a 5.1kwh server rack lithium phosphate battery. Basically it's all I need. $2200 shipped with accessories, built in BMS with temp sensor and high grade terminals, bluetooth plus RS-485/CANBUS.
fswd··on Stabilization of gamma sulfur enables 4000 cycle Li-S batteries [pdf]
the difference between 600 cycles (best 18650) and 4000 cycles is night and day. There's already Lithium Phosphate that is warranted for 6000-8000 cycles. That's 19 years. With 600 cycles your battery will hit the landfield in 2 years. A Lithium Phosphate battery will last 19 years before it has to go to the landfield. Nobody takes the environmental cost in consideration until you take away the subsidies and look at the real numbers.
