These kinds of theories along with "you just need to acclimate to it" always hit a wall when they meet me, someone in great shape who grew up around Houston (where it's miserable) and sweats all day unless it's <80F with no humidity.

Right now I live on a beach that's 85F outside and I will be the only person profusely sweating tonight while most people don't even seem to have a sheen. I first noticed it when I moved to this beach newly single and was going on dates—it's a little confusing/embarrassing looking like you swam to the date yet nobody else is sweating.

Every once in a while I meet someone like me with a body made for the Swiss mountains. And every once in a while I meet the polar opposite: someone who can walk around in the Texas summer with pants and a polo.

I think it's 90% genetic. And muscle mass only makes you sweat more.

Almost 10 years ago (damn...) I reverse engineered my air conditioner IR protocol and wrote a lengthy article about it. That being said, I was new to electronics and was doing it all on a raspberry pi instead of something embedded. Since then I've also made an ESP32 version, and many others have as well. If you're interested in more of the actual reverse engineering part, I tried to explain it from more of a beginner's perspective, because I was a beginner at electronics then:

> 63 percent of US households owned the home they lived in in 1960

Wouldn’t measuring dynamics of home ownership using a unit “households” cause all sorts of problems? Consider two people who would get married and become a “households” except they’re too poor to live together so they each cohabitate with their parents. Every household in this example that owned a house in 1960 (the two sets of parents) still does, but the example shows a pretty serious housing problem.

Oh, I hope I didn't come off as talking down to you! As I said in another reply here, the intention behind this comment was pretty narrow --- there's a certain perspective on this stuff that I see pretty often on HN that I think is missing some insight into what makes mathematicians tick, and I may have been letting my reaction to those other people leak into my response to you. Sorry for math-splaining :).

Anyway, yeah, if this scenario does come to pass it will be interesting to see just how impenetrable the resulting formal proofs end up looking and how hard it is to turn them into something that humans can fit in their heads. I can imagine a continuum of possibilities here, with thousands of pages of inscrutable symbol-pushing on one end to beautiful explanations on the other.

The solar panels installed in China during the past 2 years produce as much electricity as all of their nuclear plants combined.

Finland spent 18 years and 11 bn euros to get 1.6 GW of nuclear, the US spent 7bn in subsidies and got some 20 GW of solar in 2022 alone.

Countries going for nuclear will wait decades to get the same power that solar can add in weeks.

Nuclear basically makes no sense at all in 2025.

(For nighttime use dirt-cheap batteries and natural gas now, even cheaper batteries and generated hydrogen gas later).

> I wonder how the equivalent to the "station wagon full of tapes hurtling down the highway" looks for batteries.

Looks terrible.

I think the best are only about 500Wh/kg, so a shipping container* full of them would be 28870kg * 500Wh/kg = 14.44 MWh, so if it takes an hour to the destination it's about the capacity of one not particularly thick cable.

Cables are great for electricity. If the (aluminium) cable had a cross section of one square meter, you could get all the way around the planet and back to where you started with just 1Ω of DC electrical resistance.

If you have an expectation of privacy in any of those, you are mistaken.

One of the first things I told my daughter when I gave her her first cell phone is never text anything you don’t want someone to screenshot and send it to everyone you know.

Sure enough, literally yesterday she got a text from friend A asking if my daughter liked her more than friend B.

Friend B sent the message from friend A’s phone as a test.

The year is 2025 and sadly the only place I have an expectation of privacy anymore is inside my own house verbally speaking to my family. And even then I expect my location to be available to more people than I care to admit.

27 years in solitary confinement for collecting his tools before probate had cleared is both unconscionable and extremely American.

Solitary confinement is torture. 27 years of torture for this man who, as far as I can tell, engaged in a victimless procedural crime.

Deeply fucked up and unsurprising story if you're familiar with incarceration in the US.

Nuclear is cost competitive if you have a reliable cadence of building plants and if folks get out of the way of location permits and waste storage and people can actually make decisions about them without endless debates and lawsuits. The problem is one-off designs and the decades long gap between project inception and when investment returns start coming in. As opposed to solar where I could order a few panels and accessories online and start producing energy within a week. Obviously larger solar projects take more planning but if you've got a roof, a credit card, and an electrician on hand you can start producing electricity or expand your production in a very short time achieving break even in a few years.

Yikes. I get they're trying to push an anti-inequality agenda, but some of the statistics are only tenuously related to inequality. For instance:

>0 Number of student wellness centers in the San José Unified School District that opened in 2024, despite the growing mental health crisis in youth

>0 Number of Narcan kits stocked at San José Unified School District schools, making SJUSD the only major Bay Area school district that does not stock Narcan or train staff to administer Narcan in case of a fentanyl overdose.

What's the implication supposed to be? That if it weren't for AI tech bros, there would be student wellness centers and narcan kits?

Hard agree on pumped hydro and other forms of grid-scale storage, but can you understand concerns around batteries? There are environmental ones on the mining/metals side, but producing and disposing of them in a clean manner is often hard. Getting them from anywhere save mostly china is hard (if you want large, dense, affordable, and grid-scale options) and depending on somebody who's nobody's geopolitical friend is probably a bad idea.

Ditto for the panels themselves.

I grew up in the 90s and I agree: I shared a room with my older brother until high school.

We shared EVERYTHING. And strangely, it didn't kill us! In fact: it just motivated us to go to sports and clubs and stay out of the house.

Obviously less extreme, but I do not understand this "every child must have their own room" thing. They don't! And I grew up in an incredibly poor rural area, imagine living in a city where there was actual shit to do.

> but at least there's a fairly straightforward explanation: "`x += y` acts in-place if-and-only-if `x` is mutable".

This is the explanation. By definition it is only possible when the left-hand side is mutable; and in these cases, it's also typically convenient.

This was apparently seen as "although practicality beats purity" rather than "special cases aren't special enough to break the rules".

That is not true. Please don't spread misinformation that could lead to deaths or people losing everything they own.

You can put out a Lithium battery fire with a class-D fire extinguisher. If you don't have one available, you can isolate the burning battery by surrounding it with sand or other inert, dry substances to keep it from spreading until the fire department arrives with proper equipment to dispose of or extinguish it.

For me it's not so much a conspiracy as the natural flow as a society becomes more fascist (as most Western government are leaning) and more "police state". It's inevitable, they want to be able to spy on every aspect of our lives and keep it recorded indefinitely as technology and public sentiment will allow. Cops want to make their jobs as easy as possible, politicians want to be able to get as much dirt on everyone as they can.

Ever look at PA-RISC?

It does delay slots by turning the PC into a two element queue so the behavior of JMP x/JMP y is well defined if mostly useless.

It also makes relatively heavy use of hi/lo splits for address constants with something like 21/11 bit splits being typical.

Also has a mechanism where most ALU instructions can conditionally trigger a skip of the next instruction based on the computed value.

And as more of a local concern that just adds friction to everything touching an instruction -- constants are sliced and shuffled into smaller bitfields within the instruction in a seemingly arbitrary way (only thing that makes sense is that the sign bit of signed constants is always in the same place in the instruction).

This is great, thank you! Python's asyncio has certainly confused me more than other languages' async-await implementations.

Nit in [1]: When timing durations inside of a program it's best to avoid the system clock as it can and does jump around. For Python, prefer time.monotonic() or time.perf_counter() over time.time() in those situations.

3D Touch was amazing for typing alone, I miss it basically every day when I type more than a couple of words on my phone. It was so great to be able to firm-press and slide to move the insertion point, or firmer press to select a word or create a selection. It was like a stripped down mobile version of the kind of write-and-edit flow of jumping around between words that I can get on a proper keyboard with Emacs keybindings drilled into my brain.

Anyone with access to them. You can absolutely not read my postcards, for example, because you don't have a key for my mailbox.

Just because it's legal doesn't make it a great thing to happen.

> Is anyone surprised by `(1 > 0) < 1`?

This is presumably meant as a setup for the fact that the result of `1 > 0 < 1` differs from the result with parentheses set up either way (because this is a chained comparison), and furthermore that such chained comparisons are legal even when they don't have the operators all "pointing" the same way (like in mathematical notation). And that operators like `in` and `is` are allowed to participate in this system on equal footing.

My cynicism of NG photography is that you can't go look at the thing yourself and see it the way they show. The pictures are effectively faked though fancy camera tricks. Yea it's fascinating to see beyond our usual senses, but it's also obvious that those things are going to be strange and otherworldly so it doesn't even need to be said. Truly amazing otherworldliness would be something you can (in principle) stand there and ogle with your own senses.

Not sure what you have had to deal with but that is not my experience at all. More often than not any issues I have had with suppliers is my purchasing department was the one trying to get lower cost goods without getting engineering and Vendor QC involved.

I have never had to deal with an American supplier "downsizing" wire from one guage to the next smaller for example.

Nor as linked above, including extra electronics to exfiltrate credit card data from terminals.

I know it's popular to dump on Microsoft and there are some valid reasons, this is not one of them.

There are so many companies and businesses that rely on offline data, or silo'd data than will be tied through their AD LDAP account permission, M365, teams included, is such a better option than hand rolling all of them and praying you configured every service correctly.

Fertit actually leverages the best of both worlds through our SMTP integration approach:

Use Established ESPs for Delivery: Fertit connects to your existing SMTP provider (SendGrid, Mailgun, Amazon SES, etc.) - so you still get their deliverability infrastructure and IP reputation.

Save on Interface & Features: Instead of paying $50-300/month for ConvertKit or Mailchimp's full platform, you pay $5-10/month for Fertit's management layer while using a cheaper transactional email service for actual delivery.

Cost Comparison: Traditional ESP: $79/month for 5,000 subscribers Fertit approach: $9.99/month (Pro plan) + $15/month (SendGrid) = ~$25/month total

Your email address is actually firstlast@gmail.com.

GMail doesn't care about dots, so you could say your email address is f.i.r.s.t.l.a.s.t@gmail.com for all the good it does. Using the dot probably does more harm, as it makes people think it's a legit differentiator.

This is a valid story, and I have no doubt it’s real. I’ve heard and seen many stories like this that have happened.

But… I’m going to say the dirty, quiet, and unlikable thing out loud.

That had nothing to do with DevOps or its philosophies, processes, or patterns. That was bad leadership from the top down plain and simple. It’s likely not even the individual engineers faults. It’s leaderships fault for not setting clear objectives, implementing them, ensuring that the engineers had a real plan before beginning, and making sure no individual was too in charge of things.

Leadership in your case was likely career management who knew very little about technical items. Managers who were technical were probably shot down for not playing politics properly, not producing the correct “metrics” and “kpis”. So they moved on.

That’s a company culture issue that has little to do with tech.

You know that even inside EU, you won’t get the same thing under the same name with the same parameters in different countries, right? For example, the car which you get in Eastern Europe will have worse components than what you get in Western Europe for the same exact model. This is also true for most of the stuffs which you can get in grocery stores in multiple countries. My guilty pleasure Milka whatever has better ingredients, and the packaging contains more in Western Europe than in Eastern Europe, but the name, and even physical size of the packaging are the same. There are news also about this in Eastern Europe all the time, that groceries, cleaning stuffs, etc are worse there for the same brand and product. But it’s true also with gasoline for example. On paper, you get the same thing in Hungary, and Austria, but at the end your car will go about 10-25% more with the Austrian one, and at the end it costs the same per km, just your car will die sooner from the worse eastern gas. Every public parameter is the same, the reality is completely different.

I built my own MCP server for Outlook precisely because I didn't understand all the hype: https://github.com/Norcim133/OutlookMCPServer

With a few days coding, it was a better email assistant than any person or software I've worked with over the last decade.

I've added it to Claude Desktop and use it alongside MCPs for Notion (for DB), OpenMemory (knowledge layer), fetch (web scraping), and Xero (accounting software).

I love the general shape of this, of having some semantic record of what you browse. It's been a long goal/dream and this is an interesting neat hack to get there, a path towards that future that hasn't been open until recently.

I haven't run this yet/don't know what the UI looks like (nudge nudge), but looks like this is less for record-keeping? More for finding similar thing to what you are seeing now, although it does have a cached view?

A lot of the compensation is in stocks, sure, but a lot of compensation is also, well, in compensation. HN users have been posting -- for years -- about salaries and cash (or cash equivalent) bonuses for starting level software engineering positions at some companies exceeding $250K annually. The salary inflation in Silicon Valley's tech fields has far outpaced both general inflation and wage increases of non-tech workers in the area, so even if you're seeing San Jose Panda Express locations paying $20/hr, it's just not closing or even maintaining the gap. (And we're setting aside how many of those sorts of positions aren't actually full-time.)

For full disclosure, when I was working in Silicon Valley as a tech writer a few years ago, I was making over $200K in salary and bonuses, no stock options. Now I'm working remotely in Florida, contracting with a "managed services" company who's placed me with a much bigger tech company (one you've definitely heard of) which uses this structure to keep salaries down, and I'm making $35/hr -- and the company only pays for benefits in the most technical sense, e.g., I can buy health insurance with pre-tax money but they don't contribute any of it, there's a 401(k) but it effectively has no corporate matching, I get 10 days of PTO a year, etc.).

recently, i bought a full economy fare on an international flight. When i went to check in, they offered a really cheap upgrade to first. it was a no brainer and i was excited since the flight was gonna be ~6 hours.

i had a rude awakening when i got to the airport. This "first class" ticket was actually more like a premium economy ticket. I didn't get access to the first class check in line, no access to the lounge, no priority boarding, and the seats themselves had no extra bonus other than being in the front of the plane and slightly wider.

it was at that moment i realized there was no beating airlines and good deals aren't really that good unless you got the money to spend.

SharePoint is primarily written in C# [.NET Framework 4.8] and leverages ASP.NET; there would be no reason to rewrite the majority in another language. There is some C++ in SharePoint Search (and a few other components here and there).

IIS which SharePoint runs atop of is written in presumably primarily C.

You can decompile most of SharePoint if you ever need to peek at the code. That's a huge advantage to figure out how it works.

Yep. Anything I get from China, even from a vendor I have done lots of business with in the past gets at minimum random samples inspected and tested when appropriate. Every single shipment, zero exceptions before use.

So many things are caught. At best there is a lack of QA on the Chinese side, but it's definitely worse than that. They have no qualms sending you known-bad items, and just see it as "maybe the customer won't notice" and worth a try. It's definitely a giant pain in the ass, and adds a ton of expense and friction to the process. Lots of stuff you simply cannot source from any other country though - even if you do, the supply chain usually traces back to China anyways so all you're doing is adding a middleman layer to the problem.

It's extremely important to set very explicit and strict quality parameters and specifications prior to any deal you do with a vendor. Even then you will miss things that will later be argued about. The more you can specify the better, otherwise it will be seen as negotiable/changeable.

A lot of folks used to living in a high trust society get really taking advantage by this. Any vendor sourcing from China and not implementing an extreme level of QA to the process is being negligent, and I assume that's quite a lot if not the vast majority.

The obvious answer would've been to create a secure public API and have defender use that. But like always, corporations throw a hissy fit and implement the worst possible version of the ruling. Then people hate the EU instead of the corporation for no good reason.

It's the exact same thing as with Google Maps in Google Search. The EU did NOT say "Remove Google Maps" it said "Give competitors equal opportunity". The most user-hostile choice was removing the Google Maps integration entirely (because "no access" is still "equal access"), instead of offering users the choice.

Personally, the digital policies are one of the few things the EU generally gets right, and (as unrealistic as it is) I hope all the Googles and Apples go choke on it and di...solve.

Interestingly, one of my two big observations of LLM failure was also on an accounting task.

I thought it would be easy to do this, which is why I was surprised:

I had a folder full of bills, each of them with the VAT amount. Some were pictures, and some were PDFs. I asked for the total VAT for all 19 bills.

It took an immense number of prompts to get it to find the numbers correctly. It would get confused about reading the images as binary, that kind of thing. Or it would forget that it had to continue once it had found a few numbers. I got a total out in the end, but it took far too many prompts.

This is the only time I've come across a task a child could do that LLM failed at.

They're using Microsoft because all of the alternatives have the same issues.

FOSS isn't magically immune to vulnerabilities.

It doesn't help that the FOSS community generally prefers the C programming language over more modern and safer alternatives as a cultural thing. The result is just as many vulnerabilities, if not more, per line of code or per feature. Keep in mind that SharePoint is an enormous product with a 3.6 GB ISO image used to install it. If you think anyone is able to develop that volume of server code and have zero vulnerabilities... I have a bridge to sell you.
