I was able to find a preliminary datasheet on Google, it looks like it has 2x CAN (called TWAI in the datasheet). I can't find info on whether it has an FPU or not

It's 20+ years of Microsoft fucking with it and bringing Eternal September to our inboxes.

In years prior the email/usenet etiquette was simple: The '>' sign as the first character indicated a quote block in a reply with new content added after the quoted text.

Then came Microsoft with its Outlook and Outlook Express. First they fucked with everyone just for the hell of it by making their client top post by default. Then they brought in html into emails and usenet posts. Then they worked hard at it to make everything the mess it is today.

"That's a very defeatist and intellectually lazy point of view. "

In my opinion it is the opposite. Claiming we understand life and quarks and quarks can therefore not be part of subatomic life is the lazy approach to me. I am open for it. That doesn't mean I see indications for it, just that I am open for the concept. If I would not be open for unexpected ideas, I would never get them.

And correct me if I am wrong, but I never met a scientist who claimed to really understand quantum mechanics. Well, I heard of some who do, but they are mostly not taken seriously by the rest. So sure, we do know a lot. But understanding it?

> I think what they're saying is that you have to "save as" in order to be allowed to edit.

The issue is that roundtripping between Office 2007+ and Office 2003 is unreliable and will often result in corrupted files.

Using Office 2003 (with Compatibility Pack add-on to open xlsx and docx) is ok for isolated work but can be unreliable for collaborative back & forth editing depending on what features are used. E.g. cell colors used in Excel 2007 xlsx get corrupted in Excel 2003 xls.

I’ve been using urtext as a “Second Brain” for several years now and love it. Miles beyond any other personal knowledge and notes system.

Simply the ability to place, edit, and sort by timestamps sets it apart from other notes/knowledge systems.

Requires some familiarity with Sublime Text and ST’s quirks, and eventually an ST license is basically a necessity.

I'm not sure the end result would be lower scoring/smartness than an LLM could achieve in the same duration.

It probably wouldn’t with current models. That’s exactly why I said we need smarter models - not more speed. Unless you want to “use that for iteration, writing more tests and satisfying them, especially if you can pair that with a concurrent test runner to provide feedback.” - I personally don’t.

> Sure that's good for consumers, but its bad for competition.

So we want competition that's bad for consumers?

I have to admit I get the logic of the remedy being proposed, but something seems off to me and I can't put my finger on it. It seems different from the days of Microsoft, not just technically but in terms of the economics and consumer choice.

There's definitely stagnation in search, but I'm not convinced it has anything to do with Google paying browsers per se.

Part of me feels like there's kind of a shadow competition (in terms of browser market) that's really between Apple and everyone else, that's not being recognized by the DOJ in this. It's not this browser vs that browser, it's how you access the internet in mobile versus another way of doing so, and who controls that.

Maybe. I can't quite figure out what I think about all of this.

> Anything sent with Signal needs to be treated as published with an unknown delay.

Oddly they have thought of that already, to the point all encryption systems in use in the gov are thought of in these terms.

All that matters are the different assumed times to publication (weeks to years), and then treating the strength of measures involved differently based on what is reasonable for the given use.

If you absolutely need something to never be published then encryption isn't the solution, and nor are computers generally.

Europe has tried this in the past and the US has vetoed it. The dirty secret is America wants Europe to spend more money with American companies, not just spend more on defence. America would rather 80% of a 100b defence industry than 20% of a 300b defence industry, both from a financial point of view and from a strategic point of view.

Sad but true. If you run Teams you're more likely to be what some people would consider a slow death corporate hell hole. Thankfully last place I had like that was a husk of a company so I enjoyed a flexible work schedule since literally no one knew what I was doing and no one cared. I logged in, ran an offshore stand up, did the days activities to maintain schedule, and left whenever I wanted to. Liminal office spaces aren't so bad when you can leave anytime and get decent fast food for lunch. Good times!

The way Linux kernel stuff works, is you do a Linux internship with GSoC or Outreachy or LKMP , and then core Linux contributing companies like Intel, AMD etc gobble you up. Or you join FOSS consultancies Like Igalia, Bootlin, Collabora etc. Or you go the rockstar Patreon way like Asahi folks, trading off money for independence.

https://lwn.net/Articles/997959/ https://github.com/fossjobs/fossjobs/wiki/resources

Igalia is probably the best option for getting into core browser/etc work, they are hiring for WebKit/Chromium and are also working on Servo.

I never know if people are new to the topics or if they know the basics and want something else?

Anyway, the conventional resources were basically lists of top questions by various youtubers, they would say something like “do these 75 questions and you will be ready for most things that can come up in an interview”

Nowadays leetcode has learned about this pattern and has a study plan feature including some of those original lists: https://leetcode.com/studyplan/

Now that LLM’s can act as a tutor for these problems, I would say a study plan directly on the platform and a decent “tutor” prompt in your llm of chice will get you really far.

If the article is true, it would be worse than a cartel, it would be effectively a monopoly with a few sockpuppet competitors.

In an actual cartel or oligopoly, you'd expect at least the cartel members be relatively equal in power. But if the article is right, then Google has basically all the power to decide the course of web tech going forward, as the other browsers devs can't meaningfully deviate from whatever vision Google has for the web, without risking their funding.

It is actually View -> Toolbars -> Customize -> Notebookbar but within that there is only "Tabbed" option which doesn't really show a way to change themes.

This is a perfect example of actions that make adoption harder. This should have been at most 2 clicks and prominently displayed assuming LibreOffice wants to be a great alternative to MS Office and make the transition easier. I have been using Linux daily for over 20 years now and it is not intuitive to me - it doesn't make me very optimistic about the experience for a new user.

Like this one from the first days of the war:

"Ukraine has honoured 13 soldiers who were killed defending a tiny island after reportedly swearing at a Russian ship that ordered them to surrender.

In unverified audio clips, the borders guards defending Zmiinyi Island in the Black Sea are told to "lay down your weapons" or "be bombed".

"Russian warship, go to hell," they respond.

Ukraine says they were then killed by air and sea strikes. Russia denies the account, saying they all surrendered.

Ukraine's President Volodymyr Zelensky has awarded each of the guards the posthumous title of "Hero of Ukraine".

"On our Zmiinyi Island, defending it to the last, all the border guards died heroically," Mr Zelensky said." [0]

This senseless slaughter in response to a verbal insult was used to the maximum extent by the Ukrainian regime propaganda to convince the population and the army to fight.

All of it was a lie, of course. [1]

I believed it too and was deeply shocked by the horrible news. Of course, this trick works only once.

What an attractive opportunity: The next several quarters will suck no matter what. The PE ratio is around 150 when it could be 15. If it gets there, it will be due to a stock price collapse. For which the new CEO will have to answer to a board stacked with loyalists and relatives of Elon.

I'm sure they can find a really smart person for that gig.

I used to work at a company that had a management interface that used sqlite as database, its multi-node / fallover approach was also just... copying the file and rsyncing it. I did wonder about data integrity though, what if the file is edited while it's being copied over? But there's probably safeguards in place.

Anyway I don't think the database file size was really an issue, it was a relatively big schema but not many indices and performance wasn't a big consideration - hence why the backend would concatenate query results into an XML file, then pass it through an xml->json converter, causing 1-2 second response times on most requests. I worked on a rewrite using Go where requests were more like 10-15 milliseconds.

But, I still used sqlite because that was actually a pretty good solution for the problem at hand; relatively low concurrency (up to 10 active simultaneous users), no server-side dependencies or installation needed, etc.

You can write great code in notebooks; it all depends on you. Eg if you use vscode and not the browser for jupyter notebooks, you will have the same type checking and formatting as in the editor itself if you have it enabled.

For interactive development, repl is a joke. Sketching out a fully working prototype of a few hundred lines of code (possibly depending on some data and context you don't want to reload) is impossible in repl.

As an ex-Microsoft SDET who worked on Windows, we used to test for those things as well. In 2014.

Then Microsoft made the brave decision that testers were simply unnecessary. So they laid off all SDETs, then decided that SDE’s should be in charge of the tests themselves.

Which effectively made it so there was no test coverage of windows at all, as the majority of SDE’s had not interacted with the test system prior to that point. Many/most of them did not know how to run even a single test, let alone interpret its results.

This is what Microsoft management wanted, so this is what they got. I would not expect improvement, only slow degradation as Windows becomes Bing Desktop, featuring Office and Copilot (Powered By Azure™).

It does a lot of things, though many are somewhat subtle, like screen locking timeout and stuff with networking and a bunch of utility programs and so on. I like to start off Xfce Debian and plaster i3wm over it, it's the best 'power user' setup I've come across.

I wouldn't hesitate to put a 'regular' computer user in front of Xfce, it strikes a nice combination of simple and discoverable with very few annoyances. It's also where I go when I want to use some many-windowed application that doesn't fit into tiling.
Ask HN: Email Client
by gabeyaw | 2025-05-01 12:04:51+00:00
I'm looking for an email client for my mac. I find outlook to be too bloated, here are my requirements: 1) Multiple email address support (outlook and gmail accounts), ideally can show all inboxes in one place 2) Calendar 3) Sensible shortcuts - I'm considering learning/slowly dipping in and out of vim so would be open to similar shortcuts 4) Optional: Suggests events based of a message. If someone says lets make a meeting at 14:00-15:00 1/6/25 , I don't want it to hyperlink a phone number that is +14001500162025, I want to click once to make the meeting.

I'd rather stick with a client that will last the test of time that I really learn, than a new start up client. I really got into Arc Browser but now there aren't any more updates other than security.

I don't even use email a lot, I'm just a regular student, but find that I want to use outlook less each time I use it

The integration might be the best real reason, but IMO the real reason is branding and good marketing.

A lot of FOSS and other non-US software has at least as good UI and often better responsiveness.

However for many people particular apps they need are Windows only. Lots of industry vertical stuff.

With regard to marketing and branding, a lot of people use AWS because of the brand. Its not a particularly good provider of VPSs but I have lost count of how many people use AWS as a VPS provider (not using other services) and even worse most of them buy and instance plus storage rather than saving money by using Lightsail. I have had people argue that potential acquirers might be put off by using smaller providers.

It is due to the fact EVs relatively freeload via using roads without paying fuel taxes, and take from everyone else using ev federal subsidies.

Of course 18-wheelers and large trucks are probably worse. Small passenger ICE cars end up paying way over their share because they don't do much wear on the road but still get hit for a disproportionately large gas and use taxes.

I wasn't referring to knowledge of the Paninian sutras or pratyayas, to be clear, when I said "the basics".

For this story, you don't need to know the pratyayas but you do need to know the tenses, the ktva-lyap forms, etc to fully understand what is going on. With only an incomplete knowledge of those aspects, one can sort of intuit the overall meaning but eventually would find that they had the wrong idea altogether when reading the corresponding translation in a language they know.

Hopefully Google will keep sending half a billion a year to Mozilla (now with no strings attached). It was a good arrangement for everyone, especially for us. (Mozilla's not without controversy these days but hey, that's not on Google). I don't get why so many people are using fancy logic to argue, implicitly, that Firefox would be better with less funding. It won't be.

But it was very trashy of Apple to rent-seek off of their market power. $20 billion a year, to adopt a search engine that Apple insists, in court, they would have used anyway for free, is pure rent-seeking. Profiting off of the fact that Safari is preinstalled and has a high market-share floor (since other browsers have very limited competitive advantages on iPhone compared to Windows/Mac). Companies should be forced to compete for every dollar they earn.

Suppose you lost your phone. How would you cope with this situation? What is your laptop failed to start up? Would you have backups? Have you tried to restore them? Do you have a plan on how to get back up and running quickly?

There are a lot of things that can (and will) go wrong when it comes to computers, life, work, holiday and cats. This project will send you disaster drills when you least expect it to see how well prepared you are. It contains tips and tricks and you can score yourself and match against others on your preparedness level.

I've set this up as a small weekend side-project for two reasons: first, because i fail too often when it comes to disaster prepping myself, and secondly, I was very curious to see if I could use LLM systems like chatgpt and deepseek to "generate" apps/sites. Turns out that it wasn't too bad, although i wouldn't fire my whole development team just yet.

I’m somewhat surprised to see that they use a KVM to switch between back and forth between a JWICS and SIPRNET. I would imagine it’s a special KVM as it’s essentially bridging the airgap between the two.

If you're regularly syncing from an older version to a new version, you can likely optimize further using gzip with "--rsyncable" option. It will reduce the compression by ~1% but make it so differences from one version to the next are localized instead of cascading through the full length of the compression output.

Another alternative is to skip compression of the dump output, let rsync calculate the differences from an previous uncompressed dump to the current dump, then have rsync compress the change sets it sends over the network. (rsync -z)

The cheapest source of synthetic inertia is batteries. In places where they create a market for this the batteries win.

Solar might also enter that market strongly during daytime if the alternative is curtailing it completely.

This article from before the blackout suggest Spain is trailing other nations on BESS because they have more Hydro (and thermal? which might mean solar concentrating power) and haven't been as driven to set up the necessary regulatory environment.

https://www.rabobank.com/knowledge/d011476239-backup-power-f...

> Along with the lack of urgency around battery storage on the Spanish grids, key regulatory and market fundamentals have been lacking for the BESS business in Spain. The Spanish market has primarily relied on pumped hydro storage and thermal storage. As a result, the regulation required for BESS projects to participate in energy and ancillary services markets has been lacking, and progress in the necessary regulatory updates has been slower than in other European countries.

"Ancillary services" here mean grid inertia and similar.

Just have it suspend to disk and shutdown on lid close.

I do this for arch Linux on my framework and it's fine. Startup time is under ten seconds, essentially zero battery drain, right back in your session with all apps/docs open.

Hibernate is definitely better but still finicky even on Mac/Windows, machines can and do fry themselves, or require a hard reset if you unplug a device at the wrong time. Or unexpectedly continue draining the battery.

It's a terrible, funky, poorly documented, exception filled world down in the low power states for hardware.

I wish companies would go back to building fast apps, but alas. Everything is feature-packed and requires you to download half the internet.

My intellij license just expired so today I'm back using Sublime Text, and honestly it's a breath of fresh air / relief - and it's not even the fastest editor, iirc it uses Python under the hood. I've installed Zed but getting plugins and keyboard shortcuts all lined up is always challenging. That one took ~2-3 seconds to cold start.

>I can't believe I'm still arguing this in 2025, but here we are, from the dictator himself

Politicians often say a lot of provocative things in interviews. What matters is what they actually do and whether they do it consistently. You pick one quote from an the interview and think it is more important than all the legislative framework and all the peace proposals that were written on paper. I disagree and will not continue, since you are apparently arguing based on beliefs not based on knowledge of the facts.

>It's not complicated at all, they kidnapped children from Ukraine, their state.

As I said, your number of 700k children is wrong by order of magnitude. That number comes from a Russian source, Ukraine has a database of 20k confirmed cases (could be higher by now). Russia annexed Ukrainian territories and offered citizenship to inhabitants. Russia also hosted a number of pro-Russian Ukrainian refugees, some of them children who left the war zone with their parents and preferred to stay in Russia (yes, those people do exist and there's a lot of them). I do not deny abductions, I just say that that number includes very different cases and taking them into account will paint very different picture from "genocide".

Despite the ongoing problem of LLMs passing as human (and before that, https://xkcd.com/1019/ etc.), it is entirely possible they're 100% sincere.

First, remember that a lot of people voted for Trump despite all thay he said in the election and all that he did last time around. What he says must resonate with a lot of people, or that would not have happened.

Second, anecdotally, there's someone I used to know back in the UK who was absolutely convinced that Brexit would be a success, to the extent that at one point me simply saying "no" to some claim he made resulted in him shouting "that proves we should do it!" (or similar, it's hard to quote exactly from memory, especially 9 years later). Cambridge graduate, did the maths olympiad in their youth, still acted that way.

And third, it's very easy to get anchored on something that was once true, and not update as the world moves on. When I was a kid, "made in China" or "made in Taiwan" was not a sign of quality, but "made in Japan" was; but one of the films of my youth was Back To The Future, and one if the few things you can allow even fiction to inform you of are cultural beliefs, like 1955 Doc Brown being written to expect "made in Japan" to justify component failure.

> quarks can therefore not be part of subatomic life is the lazy approach to me

For the record, I wrote "very hard to imagine". If you claim it can be possible, it is you who must produce at least a suggestion on how it could be possible.

> And correct me if I am wrong, but I never met a scientist who claimed to really understand quantum mechanics.

I know that's a popular trope, but what they usually mean is that they don't understand it on an intuitive level. You can understand the math of it just fine.

QM is by far the most successful theory we ever had and laid the foundations for the transistor, lasers, CCD chips, solar panels, MRIs, and much more. It's responsible for arguably the biggest transformation of society of all times. You don't get there without understanding even the smallest nook of that theory.

Maybe we have different definitions of what it means to understand something, but that's not a discussion I'm interested it.
