Many people don't use semicolons (;) in English but many do, and they are certainly part of correct grammar.

Semicolons are generally alternatives to periods, when you want more connection between the two sentences. Like periods, semicolons must have two full sentences—that is, what could be full sentences—on either side of them; the potential 'full sentences' are properly called independent clauses. (A dependent clause needs the rest of the sentence to form valid grammar; it can't function on its own. For example, in this paragraph's first sentence, when you want more connection between the two sentences is a dependent clause. Often they follow commas.)

Another use of semicolons is for lists in a paragraph where one of the list items has a comma in it (similar to the parsing problem for CSVs where some records contain commas): I only like wine; beer, but only ales; and orange juice.
For an animal example with pretty specific niches, various kinds of tenrec look and behave very similarly to various types of hedgehogs and shrews, to the point that they can be mistaken for each other at a glance, but are in a completely different order of species.

I worked at the Gap and Banana Republic all through high school and college. This was well known amongst the sales staff. There's a small amount of variation between each pair of jeans because of how they're cut and how the material stretches during cutting. Also just different people on different sewing machines makes a difference. We always advised customers to try on a few pairs of the size they were looking for to get one that fit best.

Here's a quick shot of what the cutting machine looks like: https://youtu.be/oBt85Jgjvng?si=UAU0Jj4q_Vztmi5K&t=680
The problem with CSS selectors (at least in scrapers) is also that they change relatively often, compared to (html) document structure, thats why XPath last longer.
But you are right, CSS selectors compared to 20 years old XPath are realy worse.

"Couldn't find much relevant from an internet search. Sounds like..."

Maybe that is why AI barfs on it. But, yes, performance is something users universally care very much about even if many businesses aren't willing to accept that, so the question remains highly relevant. Another way a good interviewer, who has a background in performance, to consider this is to start asking performance questions that a candidate could answer from AI and the asking the candidate why some performance techniques work better than others and by how much. Then you can really see if they have a high confidence AI answer that they cannot quality.

At any point, AI answers aren't a challenge for people who are confidence enough in the craft to ask more qualified questions and determine honesty from the resulting nonverbal signals.

It looks like it's time for a government-specific form of signal, version of signal, that preserves all communications through signal for greater transparency.

The problem with doing that is governments will force us to use that version of signal as well.

> The inverted pyramid is almost always the correct format for your text. I often put the tweet-length version of the post in the title or first paragraph. Get to the point quickly, then elaborate. Means you can bail out at any point of the text and still take home most of what mattered, while the meticulous crowd can have their nitpicks addressed toward the end.

This sounds similar to what I was taught, in high school ~30 years ago, about journalism. When you write an article for the paper, the first sentence should have the who, what, when, where. The reader should be able to get the basic, relevant information from the first sentence then start giving more details as you go along. This is not only for the reader but to make it easier for the editor if/when they need to cut an article short then they can just cut text from the end.

> Elements are for data. Attributes are evil

This is like, your opinion, man... ;-) You can devise your schema any way you want. Attributes are great, and they exist in HTML in the form of datasets, which, as usual, are a poorly-specified and ill-designed rethinking of XML attributes

> Documents without a schema should not make your tools panic or complain

They don't. You absolutely don't need a schema. If you declare a schema, it should exist. If not, no problem?

Oh, I see Gemini can run code as part of the thinking process. I suppose the sandbox that happens in was the target of this research, while code editing in Gemini Canvas just has a button to export to Colab for running. The screenshots in the research show a "run" button for generated code in the chat, but I'm not seeing that exact interface.

In any case, I share your excitement.

This requires the assumption that your location and your car's location are always one and the same.

If you care about your privacy consider leaving the vehicle with tracking numbers on it at home sometimes. It's not just cops that have ALPRs and you cannot prevent this technology from existing.

> Turns out he needs an expert to hold it properly and from the coworker's point of view he would probably need to hire an expert to help automate the task, which will likely only be marginally less expensive than it was 5 years ago.

The LLM wrote the code, then used the code itself, without needing a coder around. So the only negative was needing to ask it specifically to use code, right? In that case, with code being the thing it's good at, "tell the LLM to make and use code" is going to be in the basic tutorials. It doesn't need an expert. It really is about "holding it right" in a non-mocking way, the kind of instructions you expect to go through for using a new tool.

If you can go through a one hour or less training course while only half paying attention, and immediately save two hours on your first use, that's a great return on the time investment.
> I reckon if you wanted to choose just a single rule it should be, "Write something that you yourself would actually read."

This is a good rule, and I think the first test of it is "have you suffered through proof-reading it three times?"

The garbage people write when they don't even proof-read it themselves! I find that by the third time I read through my writing (ideally spaced out over a few days) I have worked out most of its kinks.

And read it out loud! If you cannot, at least get an AI voice actor to read it for you. You catch so many more problems that way.

" It took the concepts Apple pioneered (timeslot synchronization... "

Pioneered does not mean inventing, never seen before concept.
Pioneered means in this context - taking concepts already used in other radio networks and using them in their "wifi stack". Concepts used for decades before Apple even had iphone.

I am not sure what / why is there difference between speeds of AWDL vs NAN in that table, my understanding was it can transfer at same speeds. Speed being limited by upload capability of "wifi chip".
That isn't an AI image. This thread is people winning an argument in their own heads.

It actually very much looks like the kind of ads for chemical companies you see in Japanese airports. (A funny contrast to the UK, which has decided it doesn't need to have an economy anymore so literally every ad in the London subway is for a musical.)
Sales may be falling in Canada, but lots of people own teslas in Toronto. I was just there last week and saw more Teslas and cyber trucks on the road than I've ever seen in the US.
There's generally a strong preference for those basic chips to use planar nodes. This limits them to 28nm for TSMC and 22nm for GlobalFoundries (22FDX+ fab is actually in Dresden, but they announced plans to add a second 22FDX+ fab in New York).

I do agree that more fabs in the US is better than fewer though.
I don't think some larger system wants cops ignorant, as much as it's the dynamics of corrupt self-preservation.

If corrupt sheriff Moe Carpaio is accepting bribes or selling drugs out of the evidence locker, Moe needs to hire juniors who are less likely to blow the whistle. Much of that involves in trapping them into the perpetuating cycle of crime, and that's easier when they don't have lots of other employment options.
Only if you ignore Smalltalk and Lisp environments.

There is still some catching up missing from other programming stacks.
I agree. "Planning" means we come up with alternative sets of steps or tasks which we then order into sequences or acyclic directed graphs and then pick the plan we think is the best. We can also create "Plan B" and "Plan C" for the cases that the main plan fails to execute successfully.

But as far as we know does AI internally assemeble subtasks into graphs and then evaluate them and pick the best one?

Is there any evidence in the memory traces of the executing AI that there are tasks and sub-tasks and ordering and evaluating of them, then taking a decision to choose and EXECUTE the best plan?

Where is the evidence that AI-programs do "planning"?
When COVID was spreading around china the state govt was putting out public announcements about this disease and what symptoms to watch out for.

Granted it may not be rich as other states but it leads other states in a lot of other markers
Homebrew supports both Mac and Linux

I definitely encountered packages available in homebrew but not nixpkgs, so the idea that if not in nix not in brew is wrong. Another package I use has been out of date for months, again it's quality over quantity and nix lacks the quality that i deem more important for myself

Someone else published a nixpkg for my project, but it is wrong. As an OSS maintainer, I have reduced the number of places I publish, too many packages managers these days for my limited time

Typical scientist behavior, really.
The article mentions a hydrophobic coating, like a fence around the plastic: once breached by a scratch (or by being crushed) the coating no longer keeps salt water out.

I wonder whether the coating itself is made from something terrible. In principle, though, there's your "push of a button": throw the plastic bottle in a trash compactor, break through the coating, now it dissolves in the sea.

IBM puts the number of COBOL devs at around 2 million, others around 1 million. Full-time experienced people is placed at around 200,000.

Total embedded devs are around 2-2.5 million, but embedded driver devs are a much smaller subset. Hard to find numbers but probably around again 200,000 full time experienced so roughly the same amount.

> At 60 an inheritance doesn’t move the needle much.

My in-laws gave my me and my wife about $20,000 to help with the down payment on our house when we were 35. They said to consider it an advance of our inheritance for that exact reason. $20K at that time would make a lot more of a difference to us than $20K + the interest it would have earned in 20-30 years.
If you’re running inside AWS us-east-1 then docker hub will give you direct S3 URLs for layer downloads (or it used to anyway)

Any pulls doing this become zero cost for docker hub

Any sort of cache you put between docker hub and your own infra would probably be S3 backed anyway, so adding another cache in between could be mostly a waste
Yeah but now the AI can do it! /s
I keep reading people complaining about this but I can't understand why. Gemini can 100% set timers and with much more subtle hints than assistant ever could. It just works. I don't get why people say it can't.

It can also play music or turn on my smart lamps, change their colors etc. I can't remember doing any special configuration for it to do that either.

Socialism with Kerala characteristics? I'm a bit skeptical of that, people often point to the Scandinavian model as especially successful but when you look into the data, that actually combines redistribution (funded by higher taxes) with a lot of economic freedom and a light-touch attitude from government that are all ideologically counter to "communism" or "socialism" of any kind.

> Intel should have been allowed to fail, its fabs spun off and many of its unprofitable ancillary products shut down or sold

If Intel had failed, the fabs would have shut down, not been spun off. Intel's fabs are the primary reason Intel has poor financials - continually running on a loss. Intel's Product division makes a profit - always has - and can survive.

The Bailout is all about propping the fabs, not the products. Letting Intel fail really does equate to losing semiconductor capability in the US. There's no other US company that comes even close to Intel's fabs.

The market is harsh to Intel - it's essentially saying "There's no room for number 2"

I don't think the service that 23andMe was selling to consumers was truly
scientifically based. They needed a way to attract customers, so they taylored it to be as attractive to customers as possible. 23andMe was never a business where people were the main customers. The idea was for people to use the service and then sell the collective genetic data to businesses that could use it for research and create products. $99.00 per buyer did not cover the true costs of running the business. The failure was that 23andMe could not execute on the commercialization of the generic data.

For whoever can commercialize the data that's in the vaults, the collected data can have great value.
You don't have to burn anything. You can store energy and release it later with batteries and hydraulic pumps (maybe not enough to take ypu all the way just yet, but a lot further than where we currently are).

Although, if you do want to burn something, you can burn biofuel (basically wood). The UK's only company that does this, Drax, are really not great ecologically, but just focusing on cost, diversifying from gas to a mix with more biofuel would have huge benefits.

Show HN: TalkToSales makes websites voice-controlled
Hi folks, Alex Kolchinski here - I'm a YC alum (W21 with Mezli) and Stanford AI Lab alum from before that.

Today I'm launching something new with my friend Alec Bell (a W23 YC alum) that we'd love to get your thoughts on.

TalkToSales adds AI assistants to websites: they can answer visitors' questions, give them live tours of the website or app, and even help them book follow-up calls and buy things right in the conversation.

Unlike traditional websites, which are the same for everyone who visits them, the TalkToSales assistant customizes the conversation and content shown to every visitor, whether the content is dynamic slides, a website/app tour, or both.

TalkToSales also lets the people behind a website offer to "drop in" in place of the AI assistant and talk with visitors directly, when visitors accept.
Shopkeepers in physical stores have always been able to talk to customers as they browse, but it hasn't been possible to do this on the web until now.
We think this could be quite useful for companies that do business online to have more personal engagement with web visitors.

We think TalkToSales assistants can be helpful for a number of use cases:

Software sales: the website itself can become the first sales call, answering visitors' questions, qualifying their good fit and intent, and booking follow-up calls for good leads.

Software onboarding and support: Imagine a Clippy that actually worked, talking to you over voice and actually taking actions in a web app for you as you ask it for how to do things.

E-commerce: Imagine having a personal shopper on e.g. the Home Depot website, where a virtual man in an orange apron could show you different dishwasher models and help you pick between them.

Real estate: Imagine going to an apartment building's website and having a virtual real estate agent answer your questions, give you virtual tours of apartments, and book you for a real-world tour.

(Any other ideas? We're all ears!)

We think TalkToSales assistants can also be very helpful from an analytics point of view - instead of just seeing who visits your page and for how long, imagine being able to see which questions people have, what objections prevent them from engaging deeper, etc. TalkToSales logs transcripts of conversations and the AI can surface patterns from those conversations from you.

Please try it out and let us know what you think! And if you know anyone else who'd be interested in this, I'd appreciate you sharing it with them.

If you're interested in talking about using TalkToSales for your business, or just have any more questions, please reach out - I'm at alex@talktosales.com
