sgwizdak··on Italo Calvino: A traveller in a world of uncertainty
Great article - "Invisible Cities" was my introduction to his work and remains a favorite.

Awesome, happy for your father!

Think of it this way - once you're in a state of obesity, resolving that situation is quite difficult. Eating healthy may not be enough, particularly if there are other metabolic issues going on.

The imbalance of fat to muscle leads to insulin resistance. Insulin resistance gets in the way of weight loss. After a long time of trying other means, I decided to directly tackle the insulin resistance problem. And it's been the only thing that's worked.

Sorry - I think there's complexity with insulin at play that you're overlooking. When I did caloric restriction, I was constantly battling hypoglycemic events that made me not want to exercise. I don't get that with the GLP-1s. In online discussions, people tend to conflate GLP-1 with appetite suppressants - but there's also insulin stabilization that occurs.

I started a GLP-1 in October. I've been eating healthy and exercising for a decade, but I was still in the obese category and blood sugar tests indicated I was at the edge of pre-diabetes. If I pushed hard on calorie reduction or exercise, I could gain 10-20% improvement, but it seemed like that would always reverse itself when I'd hit an injury or got sick. I'm hitting my mid-40s and decided it was time for a drastic change. I could have continued yo-yo dieting or opt for a solution that gets me to a healthy BMI within a year.

I gained a lot of weight during puberty, coupled with a less healthy diet in my youth. I suspect many folks are in the same boat - by the time they realize they need to eat/exercise, it's too late. Their metabolic system has been compromised by either diet, hormones, genetics, whatever.

In four months on a GLP-1, I've dropped about 18kg and since I coupled resistance training, I've increased on various strength parameters. The sudden reduction in weight has benefited my activity level substantially. There tends to be two classes of folks - those who need to stay on this drug forever and those who don't - I'm hoping in the end I fall into the don't, but I'm going to let the data from my continuous glucose monitor decide that.

I highly recommend the book "Ozempic Revolution" if you're considering the pros/cons of this path.

sgwizdak··on Ask HN: How do you learn Spanish guitar?
I've been playing classical guitar for a bit. A teacher who specializes in that style is your best option, but teacher quality can vary quite drastically and can be hard to manage if you're a busy professional. For an online, asynchronous resource, https://classical.guitarcorneracademy.com has been great for along with occasional check-ins with an online teacher.

The ability to load up an on call schedule would be handy.
sgwizdak··on Busy Status Bar
The mode where it sits on a monitor and displays a status ("on call") is very interesting. I think that could be simplified into a product unto itself -- but it would need to priced at "office toy" level -- so around $20-$40 USD.

Give me text boxes and arrow connects and I'll be happy to use this for system diagrams.

sgwizdak··on Congress wants AM radio in all new cars – trade groups say that’s a mistake
There are areas in the US that do not have cell/data coverage where important road information updates (think mountain pass conditions) are broadcast over AM radio.
sgwizdak··on Ask HN: Laid off folks, are you getting hired?
It's an estimate based on both the average severances coupled with how long it takes to work through the Blind 100 LC grind with a bit of reset time thrown in. If you're in a position where you can handle 2 LC-hard questions in about an hour with near perfect execution, good for you! But most folks need to prepare for that.
sgwizdak··on Ask HN: Laid off folks, are you getting hired?
One note from personal experience -- it'll likely take about 12 weeks or so for a laid off dev to come back up to speed with interview prep to feel confident to start the interview grind again. One thing that can likely help is being upfront with the evaluation process.
sgwizdak··on Ask HN: Suggestions for working effectively with junior devs?
Clear out what your obligations are with your management.

I've been in positions as a senior software engineer where it's my job to carve up projects and have make sure juniors can get things done. That means checking in with them, make sure they understand stuff, make sure quality is high, and ensure they're not getting blocked. Your management looks to you get the project done. You are not measured by your IC but by your ability to force-multiply to knock out projects.

In these situations, your individual IC contributions go down, but you effectively get to claim delivery of the project under your belt based on ensuring delivery success. (It may be critical in these situations to track how you made that happen.)

sgwizdak··on Ask HN: Do you use a physical calculator in your day job, and why?
I still use my HP-32sii [and more recently, the remake, the HP-35] for dev work. I use it mostly for calculations involving hexadecimal values when I'm in a debugging session.
sgwizdak··on Schools should be using open source software
This article discusses end user applications, but nothing regarding the classroom experience. (E.g., how does the teacher monitor individual screens to ensure they're staying on task?) My wife is a teacher and google classroom is what most of the districts in this area leverage.
sgwizdak··on The Beautiful Mind-Bending of Stanislaw Lem (2019)
There was a recent publishing of Lem's lesser known short stories that is excellent: "The Truth and Other Stories" https://www.amazon.com/Truth-Other-Stories-Stanislaw-Lem/dp/...

There is a translation of Solaris by Bill Johnston that is available as a Kindle e-book that is a direct translation from Polish. IIRC, there are licensing issues with providing a print version of it.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
I used the stock charging cable which is USB A -> micro-USB. That either connected to a laptop with a USB-A or through the apple dongle.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
The QC-35 II's were great for concalls. You can connect multiple devices at once via bluetooth and the mic quality was quite good. For music, I agree there's lots of better options. I've now using an external microphone and some wired DT-770's, however it's not a great portable solution.

It was more like a $20 discount. It took a bit of prodding for them realize this was a safety issue and get connected to the right team, but I had no complaints on that. No comment regarding the rest of the process, it's still too early. The intent of the article was to highlight a potential issue with a pretty common pair of headphones that's used in the tech world, and one that I used to personally recommend to people.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
Yes. That's exactly what I did. Doctors think this significantly helped, but we'll know more in a few weeks.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
Some of the safety issues could be alleviated through different product design. For instance -- the charge system is a USB cable direct to the headphones. A fireproof cradle might be one option to handle to at least mitigate for unattended thermal runaway. In fact, a fireproof box in which to charge portable devices might not be a bad product idea.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
I actually never cared for the noise cancellation on the QC-35 II. I did use it on planes though. I liked the feature a bit better on the earlier wired model. I think Sony has a comparable product where it has a finer grained toggle of the inverse wave.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
Thank you, filed.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
Things happened very quickly. I managed to get the headphones out of the house in under 10s. I may have been screaming obscenities at the time. I just recall a sticky residue somehow ended up on my hands and that's what burned. There was also some burning from thermals. I obviously tried to hold my breath to some extent, but the smoke persisted in the house for a while.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
I never thought that my wireless headphones had enough juice to fill my house with smoke, to burn for 15 minutes, or result in chemical burns to the user.
sgwizdak··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
I never thought it would happen to me either. I knew the risks. I took care of my devices. I treated my devices with lithium ion as a loaded gun. But it happened. It happened suddenly, and if I wasn't present, it would have taken out my home and killed my pets and possibly my wife.

I wrote this not to shame Bose. But to highlight the risk of personal wearables and lithium ion technologies.
