Cellular networks.

I specialize in computer networking in my day job. Most of what I do is Cisco routers, Cisco switches, and Cisco firewalls. I would be interested in learning more about cellular networks. I haven't put any effort into exploring this for myself. If there is a track similar to CCNA → CCNP → CCIE then it isn't well-known (well, not known to me).

Autocrats don't believe in immunity -- they instated it, and they understand others can repeal it at any time later.

Case study -- Kazakhstan leader, Nazarbayev introduced all kinds of immunities before leaving. Didn't help later, all the titles and privileges got stripped. The only chance is to lose power and money and become harmless (and whole family as well), or get unreachable (keep the money).

PS: Autocrats like "small" wars, something that keeps people occupied and centralized. Not a large risky wars though, with unpredictable outcomes. "Small" is relative, e.g. for China a war with Taiwan very well might become "large", if India expresses an opinion on that. So they're reluctant to start it. For Russia, war with Ukraine anticipated to be "small", although grew up larger than expected.

So as I see it for Trump, a small war would be desirable, he envies Ukraine president, as they cannot conduct an election during war (and some territories occupied), that'd be nice for Trump.

Gemini is the best model in the world. Gemini is the worst web app in the world. Somehow those two things are coexisting. The web devs in their UI team have really betrayed the hard work of their ML and hardware colleagues. I don't say this lightly - I say this after having paid attention to critical bugs, more than I can count on one hand, that persisted for over a year. They either don't care or are grossly incompetent.

Claude has been particularly bad since they released 4.0. The push to remove 3.7 from Windsurf hasn’t helped either. Pretty evident they’re trying to force people to pay for Claude Code…

Trusting these LLM providers today is as risky as trusting Facebook as a platform, when they were pushing their “opensocial” stuff
Ask HN: Best cheap tablet for home dashboard

I built a little web application for my home showing today's calendar, weather etc.

I was using an old iPad for display but noticed today the battery swelling.

Any recommendations for a cheap Android tablet (10 inch) that's only purpose will be to show a very simple PWA?

I've found a few in the $40-$60 range but they're all generic brands.

All costs are not equal. There is a classic pattern of dogfights for winner-take-most product categories where the long term winner does the best job of acquiring customers at the expense of things like "engineering to reduce costs". I have no idea how the AI space is going to shake out, but if I had to pick between OpenAI's mindshare in the broadest possible cohort of users vs. best/most efficient model, I'd pick the customers.

Obviously, lots of nerds on HN have preferences for Gemini and Claude, and having used all three I completely get why that is. But we should remember we're not representative of the whole addressable market. There were probably nerds on like ancient dial-up bulletin boards explaining why Betamax was going to win, too.

"/bin/sh does not point to bash" is not the same as "does not use bash for scripting"

On my system there are 42 scripts in /bin -> /usr/bin (merged) that start with some variant of `#! /bin/bash` and at least two that do `bash -c`, but that's excluding who-knows-how-many scripts that look slightly different or are in other directories.

And keep in mind that on Debian, almost all first-party software is implemented in Perl, with a small minority in Python.

Legs? To jump into the workshop pit, among other things. Palms are needed to hold a wrench or a spanner, fingers are needed to unscrew nuts.

Cars are not built to accommodate whatever universal repair machine there could be, cars are built with an expectation that a mechanic with arms and legs will be repairing it, and will be for a while.

The same thing that happens to every OS, features and bloat.

That said, Pixel devices all the way. No gross UI reskin, no having multiple copies of the same type of app (Samsung camera vs android camera, dialers, keyboards, etc.).

Fast, stable, good features.

If it's not a pixel device, you're probably going to have a "mid" experience.

ChatGPT 4o waffles a little bit and suggests the Microsoft Entertainment pack (which is not productivity software or MS-DOS), but says at the end:

>If you're strictly talking about MS-DOS-only productivity software, there’s no widely known MS-DOS productivity app that officially had a built-in Connect Four game. Most MS-DOS apps were quite lean and focused, and games were generally separate.

I suspect this is the correct answer, because I can't find any MS-DOS Connect Four easter eggs by googling. I might be missing something obscure, but generally if I can't find it by Googling I wouldn't expect an LLM to know it.

A critical step in the researchers' protocol is reacting molten titanium with yttrium metal and yttrium trifluoride or a similar substance...

A limitation of this work is that the resulting de-oxygenated titanium contains yttrium, up to 1% by mass; yttrium can influence the mechanical and chemical properties of titanium alloy. After solving the yttrium contamination problem, applications to industrial manufacturing will be straightforward.

Any thoughts how they'll do that?

Your linked article is specifically comparing two different versioned snapshots of a model and not comparing the same model across time.

You've also made the mistake of conflating what's served via API platforms which are meant to be stable, and frontends which have no stability guarantees, and are very much iterated on in terms of the underlying model and system prompts. The GPT-4o sycophancy debacle was only on the specific model that's served via the ChatGPT frontend and never impacted the stable snapshots on the API.

I have never seen any sort of compelling evidence that any of the large labs tinkers with their stable, versioned model releases that are served via their API platforms.

Well, I'm have a little guilty bias towards spacetime non-substantivalism and I've always been interested in getting back to physics in this area. I've particularly found the Shape Dynamics program to be at least somewhat interesting and while I have a sort of ok grasp of the language and mathematics of GR translating that to the SD world has been a persistent challenge. If I had time I'd try to figure that out.

Briefly, one usually formulates the theory of gravity in terms of a a 4d spacetime with curvature but you can also formulate it as a theory of curved 3d shapes if you allow the lagrangian to carry more structure. This is often performed in GR, in fact, by decomposing the metric into a "spatial" and "temporal" part but shape dynamics kind of runs with this idea in an attempt to formulate a totally relational version of the theory of gravity.

Shape Dynamics apparently produces a reasonable theory of gravity which agrees with GR in many situations but forbids, I believe, closed timelike curves, and may be more amenable to quantization since it re-separates space and time.

Anyway, it all seems very beyond me, maybe even if I had the time, which I do not.

I can't say I'm surprised, TBH. I had a rough idea of where the problem might lie just by reading the title of the post. But I was fortunate enough to do an undergraduate degree where concurrency was actually taught, plus I've learned a lot over the years working in highly-concurrent, asynchronous environments.

Concurrent programming has been mainstream for some time now, but I don't think the level of expertise of most engineers has kept up. That becomes most apparent when software starts hitting concurrency pitfalls: performance problems, deadlocks, UAFs, and so on...

Sounds like a typical blurring of responsibility through bureaucracy. "If Zak is a billionaire, then he is responsible, but since he essentially did nothing wrong, then no one will be held accountable." Total nonsense.

There are specific crimes, and there are specific people who planned this crimes, specific peoples who ordered them to be carried out, and who carried them out. And these people should be held accountable for these crimes. Even if they work 60 hours a week for minimum wage and would have been fired if they hadn't committed them. They should have quit in such cases, not committed crimes.

And on the other hand, if your employees, without your knowledge, somehow decided that the only way they could reach their targets was to commit a crime, why should you be held responsible for that? Even if you have 20 megayachts and your employees work 60 hours a week for minimum wage.

The person you're responding to didn't mention "feeling". They made a moral statement. Feelings are something we deal with, morals are something we work to build. Confusing the two will lead to a very confusing life.

Additionally, your examples are passive. A more appropriate comparison would be "Would you not be more sad about killing a human child instead of a cow?" Of course you would be! But what if you didn't have to do either?

Same background as me, however I moved into cellular/mobile - not really any official routes I know of in the industry, certainly not like a Cisco track.

Typical route is work at a Telco or IoT company as Network Eng or Developer and naturally pivot into telco learning on the job.

Vendors will run training courses when you buy their kit which helps a little, but it’s mostly self learning or on the job.

I've used an Android and Apple phone on and off since the first phones were available with the respective OSs. In general, I've found the Android UI to be more intuitive (although they've both had their boondoggles).

But lately it does seem like spinning wheels on the UI front for both. Without a distinct new feature to build the UI around, most UI changes just seem like change for the sake of change (ie. resume/executive driven design). Both OS seem to be approaching a very similar paradigm (Apple becoming more androidy IMO lately). Minor changes aren't going to cause major changes in popularity. "Liquid Glass" does seem to be uniquely disliked, and probably for good reasons, but Apple generally has ecosystem and brand lock-in that will put the brakes on much ship jumping.

Learning just enough for your needs is a valid approach to learning electronics design, unless you're planning on becoming an actual EE.

It provides a huge amount of self-motivation and as much as I hate to admit it (as a one-time electronics design engineer), you can skip a lot of the middle-layer concepts. Sure, you should understand Ohm's law and what basic components (resistors, capacitors, transistors) do, but you can jump from that right into understanding how a battery charger works without having to understand how the components actually work.

The hard part is finding good tutorial material that starts at the right level: most of the professionally written stuff presupposes that you're either already an EE, or have one at your disposal to translate things for you.

I wish we had a dozen phone companies instead of just two.

Please write your legislators and demand antitrust action against Apple and Google for the following:

- Lack of One-Tap Web Installs (without scare walls or buried settings menus). This is the biggest stranglehold they have. Web installs can be done safely and securely via app signing, permissions, and signature blacklists.

- First-party defaults for all the platform pieces: Messaging, Payments, Photos, Music, Media, Navigation, etc. Every single one of these lets Apple and Google squeeze another industry and forces us into a pit of no-innovation.

- Default search, in the case of Google, which ropes you into their search / ads funnel. They've also bought it out on Apple's end.

- Default browser tech, in the case of Apple. It prevents innovation on app runtimes and deployment and forces you to develop using Apple technologies.

Winning the mobile rights battle will not only liberate us from the "promo cycle" plague, it'll stop the tax on innovation and introduce healthy competition.

If American legislators and the DOJ / FTC won't act, then every other country should. If enough countries put pressure on Apple and Google, we'll start to see competition reemerge. Right now it's impossible to develop a new smartphone entrant. Even Meta and Microsoft with their nearly-unlimited capital couldn't fight off Apple and Google.

YCombinator would probably be happy if smartphones became open platforms. They'd see healthier margins for startups and less direct platform competition. a16z is pushing for this. Just because Apple and Google were there first twenty years ago shouldn't give them an eternity to rule the entire category.

years ago, a friend of mine built something functionally equivalent to Denuvo in his spare time over the span of a few years. I think his original idea was "DRM for the little guy", recognizing that indie games probably lose massive revenue from initial release piracy.

He had no idea how to sell it. After it sitting around for awhile, I tried pitching the technology to few friends in VC, who had absolutely no idea what I was talking about.

It bothered me for a long time to see such a culmination of talent and effort get 0 reward for it. I've wondered if such technology would be interesting to some large publisher to just buy outright, bringing their anti-piracy in-house rather than relying on Denuvo. Any ideas/help appreciated :)

I've wanted for years to take the research paper "Coq: The World's Best Macro Assembler" through several of its more and less obvious next steps, including re-implementing it on top of a formal specification of ARM (or RISC-V) machine code, and introducing a concept of virtual registers on top of a (light weight) register allocator. I really feel like there's a path here to a system in which low-level non-portable code can be written comfortably (if perhaps at a somewhat slower pace than C), with arbitrary correctness properties proven on it; but the learning curve to get there (through Coq, etc) has been a struggle. Every few years I set myself the goal of a proven-correct implementation of a min/max heap in assembly built on this approach, and every few years I give up.

> You follow a religion because you want to be given the word of God to follow. Not the word of a man who pretends he is at the same level as God so his reinterpretation weights the same.

. . .

> You take God's word at face value, no interpretation, no exceptions.

But your judgment that god's word must be understood in this way just reflects your own belief about how god has chosen to communicate with us.

And it's actually a belief that does not give god very much credit. Great books convey meaning in numerous different ways at the same time. Why would you assume that god has written a text that operates on the level of an Ikea instruction manual when he could have used all of the tools available to great literature — and, through his omniscience, used them perfectly to speak to the needs of different readers in different times and places?

Ask yourself this: when you read scripture, does does it seem more like an instruction manual or a piece of literature?

The day after Kent State, a Gallup poll found 58% of polled Americans blamed the students for being shot. 31% had no opinion, and 11% blamed the National Guard.

After the National Guard shot a few kids for literally no reason (nobody had ever been given orders to fire), they told the student standing around "Disperse or we will shoot again"

This has never been a problem for the party of Roger Stone who literally has a large back tattoo of Nixon and is one of the primary reasons we had Bush Jr as president even though Al Gore won the votes when the count was allowed to finish

To be clear, not necessarily sentiment analysis of the email (the pre-LLM kind, like are they angry, aggressive, etc.); but sentiment tally about voting on the legislation, like a phone operator might do, which might only be identifying which bill/issue is being talked about, and whether "vote for" vs. "vote against".

The limitations of that is part of why I suggested that following up with review of the email by a human later, for nuance. The other part is so they know they're reaching a human at their representative's office, not just talking to a machine.

I don't know much about politics other than Sorkin-esque TV dramas, but the original Web page said that timely tallies could help a politician avoid being in the situation of having to walk back a stated position on something. So I'd guess that's one way a real-time tally could still be very valuable, and I think an LLM is up to the hard parts of it.

Yes, yes, Excel is the Blub tool. Plenty of other options which are better typed, performant, intuitive, whatever.

Every F500 company has accountants, FPNA, auditors, likely even the CFO who are doing their analysis in Excel. They live and breathe it. It is their everything app which they run 40 hours a week. They know Excel, they are the 10x rockstars of their field.

It is a common refrain here that you should absolutely invest in SAAS tools at $/month if it makes your workers more productive. Even if they are not slinging code, these people already have the best tool for their job. Making them all switch to save a few bucks to a less feature complete option is hamstringing yourself.

Could many people switch without issue? Sure, but it is foolhardy to imagine a 100% cut over without enormous pain to the elite staff.

This knee-jerk reaction is correct more often than not (see the terrible iOS redesign announced earlier), but in this case it seems like it might be incorrect?

I looked through the highlights linked here and the full "What's New" page [0] and am pleasantly surprised to see a few new features but no major overhauls of existing ones.

This gotta come up with a project you want for yourself and make it. I remember soldering one of those 2x16 LCD screens and it had a short so it would start smoking to designing/3D printing my own quadruped with an IMU/navigation. I did cheat and not use inverse kinematics, I watched videos on other insect-style quads walking and I programmed it manually.

I think main gotcha is power distribution and shared ground eg. using a boost converter or regulator to boost/downgrade voltage and which servos/sensors uses what. Later have to be concerned with too much current being drawn but yeah.

I used these green proto boards you can solder onto as a step up above breadboard but not my own PCB.

Agreed.

I find it interesting that LLMs seem pretty good at spitting out SQL that works well enough. But on the other hand LLMs seem pretty awful at working with CSS. I wonder if this is due to a difference in the amount of training data available for SQL vs CSS, or is this because CSS is a finicky pain in the ass when compared to SQL.

Yes. Make them a front end to project database you pay someone to host. There is one source of truth for the whole team, front ends are tailored to design disciplines, and development branches are created as needed. This is an obvious product that would be a major improvement that doesn’t exist.

Bentley and Autodesk have a Frankenstein version of this because they can’t disrupt their revenue stream for CAD software that stopped improving 20 years ago. iTwin (yes, the branding is that bad) is an attempt to link cloud to local-file-based work. ProjectWise was a first stab at that, which is worse than plain network storage in every way except that CAD managers don’t have to be responsible for configuration scripts.

I think it's more accurate to say that Socrates was improperly sensitive to the climate spartan dictatorship had brought about, esp. that he had been a mentor to some of those involved. If he had been more politically-minded, he'd have given some actual apology or shown at least some sensitivity. Instead, of course, he resented being forced to attend to non-philosophical matters.

If this device will be sitting on your home network constantly, I'd be considering another device from a trustworthy brand that gets updates.

If it shows the same thing constantly, I wouldn't want OLED.

An iPad (basic) 8th gen or newer is still supported by the next OS release and likely will last longer than a generic device.

It would likely be worth buying a tablet from a large brand with good battery controls & settings like battery life longevity management. I'd recommend using a smart outlet to cycle the tablet on and off of battery regularly in addition to using the 80% battery rules.
