We do Otel metrics for the main things needed in dashboarding
1. Requests (Counter)
2. Tokens (Counter) (Seperate metric for Prompt Tokens, Completion and Total Tokens)
3. Cost (Histogram)

I did attach a Grafana dashboard too (Works for Grafana Cloud, Ill get something for OSS this week)

Since Otel doesn't yet support Synchronous gauge + Users wanted a trace of the LLM RAG application, We opted to Traces which is quite standard now in LLM Observability tool.

Lemme know if you had something more in mind, Love getting feedback from amazing folks like you!
Doesn't matter what conductor you use to move heat, the same amount of energy will have to be dispersed. And watercooling just implies more intermediate steps between the heatshield of the die and air. So I don't believe the heat signatures can really be helped.
> No more so than "vaccinations cause autism" or "homeopathic medicine works" or "the stars direct your fate".

For extra fun/rage/narrative-catalyzing: negate your claims and re-ask the questions.

> It's an unsubstantiated, novel claim about causation that has no peer reviewed research to support it.

Do claims of nonexistence have a burden of proof, and if not:

a) why not?

b) can you cite any authority that explicitly asserts that they do not (as opposed to only pointing out the epistemic difficulty (teapots, etc))?

And even setting aside those rarely considered details:

> "It's an unsubstantiated, novel claim about causation that has no peer reviewed research to support it."

...even if we assume this to be true, do any specific necessarily correct conclusions derive from that observation? (And if not...actually, I think we have enough to chew on for now).

> But to present it as fact requires[!] extraordinary evidence.

I bet this isn't actually true, but let's see.
I believe it's just ergonomics. There's no reason to use the arrow keys if your fingers are already on hjkl. The pinky motion is highly impractical, and moving your whole hand is also. Therefore the only reason to use them is because you have the habit, and the idea is to replace that habit while editing with the hjkl keys.
Medicare only comes in if the recipient is over 65 (or some edge cases of disability).

Paying for health insurance premiums with pre tax dollars is tied to employers, or you can do it if you are self employed.

By and large, you can purchase the same health insurance that an employer offers on healthcare.gov, that meets the minimum ACA coverage standards.

However, there is no reason for employers to be able to compensate employees with pre tax dollars via subsidizing health insurance, but an individual cannot buy health insurance with pre tax dollars. That is just a handout to big businesses to give them an advantage over smaller businesses.

Also, employers compensating employees only in straight pay only also makes it easier for employees to compare compensation offers.
> Do words evolve by mistake, or do they evolve because we need to say something and we don't have the right word for it?

Both, I believe. See also linguistic descriptivism versus prescriptivism. And the words cromulent and embiggen.

It’s really cool. Have it integrated with other projects in the landscape?
You can of course get plenty of "refactor" plugins for vim out there but I've never found a need for one. Even in more complex codebases with multiple instances of a local variable like you mention, I tend to do more "find-and-replace in selection": V to Visually select a block, then just :s/foo/bar/g
Bemused (https://www.merriam-webster.com/grammar/can-bemuse-mean-amus...) is another word that is often understood "incorrectly".
Funny. In my head, nonplussed was near-synonymous with unimpressed. So in my interpretation they were neither not paying attention, nor in over their head -- but the blank stare remains nonetheless. That still closer to your interpretation than "baffled, perplexed" as it apparently originally meant.
The benefit of hjkl is that it keeps your fingers on home row. I see your point that it could be considered dogmatic, though. Personally, I'm a fan of hjkl.
This isn't authoritative in the slightest, but having lived in China I got a general feeling that Chinese see themselves as a third world country that's kinda backwards and trying it's best to catch up. This was my sense talking to normal people that sell noodles and whatnot. There is a kinda separate ultra nationalist crowd that probably see things different, but they don't really represent the majority. I think landing on the Moon is symbolic of that zeitgeist of "catching up" with the West and Japan

By contrast Indian colleagues seem extremely nationalistic - in a way that's a bit scary
> TikTok ban bill could make it impossible for most ByteDance apps to operate in the U.S. unless the Chinese firm sells them to U.S. companies.

Factually incorrect. The sales must simply be to a non-foreign adversary country buyer.
> Seems like a logical progression of technologies to me. You could throw FAX machines in there.

The implicit assumption seems to be the latter technologies in the list are strictly superior to the former, which is completely false. The article says this:

> Technological leapfrogging occurs when an industry or market (usually an outmoded industry or emerging market) skips a step along the technology transformation chain.

> Instead of learning to use a personal computer and then a mobile phone, you skip right to mobile. In many emerging markets, mobile is the dominant computing paradigm.

That kind of leapfrogging actually seems like a massive handicap. Mobile phones have severe limitations compared to PCs as devices for productive work.
I always love how the new "shiny" AI will help an industry, despite the fact that old "boring" AI has not even penetrated yet.

The article specifically mentions agriculture, where machine vision has barely been deployed, and the company that is making the automatic pest / weed killer using lasers and MV is still in a "trial".

A case of: When AI is your hammer, everything starts to look like a nail.
> When you come to spend it, that amount is transferred to another bank, that they can then offset against their own magic money.

No. The other banks demand settlement in outside currency. In the olden days, they shipped gold around every so often. Nowadays, in the end you settle in central bank deposits.
JavaScript's behaviour in this case is consistent if we accept that JavaScript would always rather compute the next-best gibberish than throw an error.

While `1 / 0` is not a valid operation, it can be interpreted using limits. If `x` approaches 0, then `1 / x` will approach `Infinity`, hence JavaScript's result of this operation.

But with `0 / 0`, there is no unambiguous interpretation, so JavaScript defaults to `NaN` as its indicator for when a number is expected, but not received in valid form.

I'm not defending this behaviour of the language, just pointing out that there aren't "two different ways" of wrong behaviour at display here.
I think you're on the right track but not quite there.

The incentivized behavior for insurance companiese right now isn't fast review, it's fast denial (which saves money on both review time and insurance payout). We need to make a coverage denial take an order of magnitude more time and effort than an approval, so insurance companies are forced to think real hard about denying access to care, and are incentivized to only deny care in relatively extreme cases.

Raise the bar for denial reasons, and forbid generic denial templates.
Do you really think hackers don't know about the User-Agent header?
> Imagine a conversational interface with much less latency

With current models the latency comes from processing, not from the network — going from a high-power remote server to a low-power local phone is likely to increase latency more than it reduces it
Cigna denied my claim for an ER stay for a broken leg because it "wasn't medically necessary". This whole "click and close" thing is so obviously happening that I find it hard to believe that the company is even bothering to deny that they do that.

One of the worst parts about this for me was that while I was dealing with trying to get my life back together from that kind of injury, I thought I was also going to go bankrupt as well.

In my case, everything did turn out fine because apparently the hospital has an entire department dedicated to dealing with insurance claim denials. This whole system is an absolute joke.

Can that be assumed? A lot of people retiring may not be very productive in those last years, and if they're replaced by automation it could very well be that total productivity goes up when they retire. I wouldn't assume that either, my point is that I don't think either of these scenarios is a given.

You should have read the article, they explained it in the second paragraph, and I have no idea why anyone would assume it's because of AI.
This definitely is the case for medical procedures and surgeonts carry high insurance for this. Not sure how this would work for diagnosis though. It's harder to know you were misdiagnosed and even harder to proof they could have done better with the information available at the time.
I always read it as meaning something like "unfazed" before seeing someone get corrected on it.
The Texas case is a great example of the hysteria. The risk was to the child, which had a low likelihood of survival after birth, but not a zero chance. There is a woman in her 40s with the condition. Drs. Could not show how it would reasonably harm the mother to carry to term. The abortion guaranteed the death of the child.

I don’t mean to make light of the situation, and knowing your child will have a serious condition prior to birth is devastating and heartbreaking. Learning your child has a serious condition after birth is the same. Only in one of those situations is the option given to end the child’s life without further care.
Has anyone solved this problem?

Yes, many here use aliases a.k.a. canaries in this case on mail providers that support this or on their own mail servers they self host.

- One can change their email with each vendor to use a specific alias. Fastmail is an example of one of the mail providers that supports this. Create unique aliases for each vendor and put the vendor name in the comment field of the web interface but keep the alias generic and realistic enough that the vendor does not reject it or realize that it is a canary. Once you are confident you have done this for ever thing you interact with, create a rule to dump all emails from your previous email address into a folder, mark as read and maybe check it once a week or month, flagging the UCE as spam. Fastmail have several domains you can create aliases on, and/or you can also use your own domains.

When a company starts abusing one of your aliases, you now know who leaked or cross-marketed your email address. You can create a rule to move emails to that alias into a folder and mark as read. Or if its 100% garbage, a rule to move emails sent to that alias to Trash and set the retention policy on Trash to a month. Optionally contacting them and voicing your dissatisfaction and that you have voted with your wallet.

- Specific to your Unsubscribe request, mail providers like Fastmail also support making rules on email content, so one could add a rule saying if the Body contains "unsubscribe" to move it to Trash and mark as read.

- Another method which only a small set of people here use is to self host email which is a big topic in and of itself then create DISCARD rules in Postfix and/or block CIDR blocks of email campaign providers yes, this is heavy handed and can drop non UCE. On my self hosted mail servers I can REJECT an email and give the spammer a friendly message of my choice. So if the body contains "unsubscribe" I can REJECT the email, at the risk of that company deleting my account which saves me the time of deleting it.

I'm a boomer, so I see things differently than younger generations. Nevertheless, I think that solid, heartfelt advice to young people looking to advance in this rapiy changing environment should consider the following:

1. Become an expert in using and augmenting AI tools to accomplish your work, whatever that may be. There is a difference between average and expert in the results that can be obtained. AI expertise will be important at least for the next 10 years.

2. Commit to lifelong learning and adaptation. The constant for the remainder of this century will be continuous, exponential change. When change has a slope near vertical, this should be apparent.

3. The closer you can be to hard science and technology in education and work, I believe the better chance you will have to make significant professional contributions. The CEO of Nvidia said as much in a recent interview.

4. Make a plan by looking at every professional career option and ask this question: "what is the likely result for this field when AGI becomes real and commonplace?" Then choose to examine more closely those fields where you believe you can thrive in the midst of change.

I hope this is helpful, and enjoy the journey!

I don't understand what the "publicly available" means. I tried some of them and they seem to require logins or paying accounts. Does this mean that for such streams, I'm in a geo-restricted area? I wonder where some of these would _not_ be geo-restricted (especially e.g. "Canal+").
The key factor is the line width, or the range of frequencies over which the transition can be stimulated. The ratio of the stimulus frequency and line width is one way of expressing the resonator Q factor. In general, the lower the line width for a given transition, the higher the Q, the better the signal-to-noise ratio, and the more stable the resulting clock. (Imagine how much more precisely the frequency of a large bell could be measured compared to a cymbal or something else with a broader acoustical spectrum.)

Cs or Rb clocks give you a line width of a few hundred Hz at 9 GHz (Q=roughly 100 million), while quantum transitions in optical clocks can achieve line widths on the order of 1 Hz in the PHz region (equivalent Q in the quintillions.) There is a lot more to building a good clock than high Q, but it's a very important consideration ( http://www.leapsecond.com/pages/Q/ ).

What caught my eye is the ringdown time of the stimulated optical resonance, apparently in the hundreds of seconds. They talk about line widths in the GHz range, but that seems to refer to the laser rather than the underlying resonance being probed. It would have been interesting to hear more about what they expected regarding the actual transition line width. Probably the information is there but not in a form that I grokked, given insufficient background in that field.
This is one of those areas where money can solve your problem. It's a lot harder to rebuild if you're not making good money. Especially for those who are on the hook for alimony & child support.
The risk in a call center is generally that someone won't have their issue fixed and will have to call again tomorrow. I would say the risk in denying treatment to a cancer patient is a bit higher than that, so every patient should be entitled to a review of their case that is not skewed to increase the insurer's profits or rushed to meet some "productivity" metrics. Of course doctors shouldn't spend infinite time on a case, but if the only way to not fall behind is to quickly deny cases, then something is wrong...
In the sense that the outcome was not maliciously intentional, yes. Doesn’t mean they bear no responsibility, of course, or that their egregious actions didn’t cause it—just means they didn’t set out to do it.
Can you name a provider? I personally use Stripe Tax for my business and while they will calculate the taxes you owe in each municipality it is totally on you to create an account with each country/state's Department of Revenue and fill out a form quarterly to submit your payments.

This paperwork is what I believe a marketplace like the App Store or Amazon do for you under their own entity that you have to do yourself if you bypass their stores.

Please correct me if I'm wrong.
Many people who advocate for technologies appear to have zero capability of understanding that the world exists outside of their own understanding, so aren't even capable of forming questions like "how was this done in the past?" or "are these problems real?"
And probably the only real at-scale deployment of the Western Electric 32000 (Bellmac 32) processor. Sadly that chip wasn't very popular.

As LeoPanthera said above, Bell's exchange for the ability to make PCs was a bit of a bad swap in retrospect. It's pretty easy to see they were going for some kind of convergence of computing and telecoms (the 3B1 has an internal 1200 Baud modem) but they didn't do well on that bet.
Even when we had Internet forums (PHPBB and whatnot) the admins would assert their influence and moderate unfairly. Only turning back to an ecosystem of individually owned sites would counter the over moderation, but even then, you still have the issue of SEO and Search Result manipulation to battle. :/
As someone with ADHD, I concur.
Yeah, sure. I guess you can say that a driver who hadn't slept the night before and was super stressed out about work could've fallen asleep while driving on a monotonous and boring highway, but he also might not have. Yet, at the end of the day, it's far more likely that he would've fallen asleep either way.

I feel like this distracts from the fact that the self-driving feature was probably safer than falling asleep at a manual car for everyone involved.
Ask HN: How do you give developers database access?
We want to keep our databases secure, but sometimes developers need access (think migrations, debugging, business information queries).

Ideally, database access is:

- Connected to existing developer authentication (single sign-on)

- Time limited

- Requires approval

- Leaves an audit trail

How do you achieve these conflicting goals?

Some approaches:

- Put the database in a public subnet and give developers database credentials. This is strongly discouraged by AWS etc (why?). No audit trail or approvals process.

- Put the database in a private subnet with a VPN in a public subnet. Give developers database credentials. This requires credential management for the VPN and you need to pay for an additional server. Access is not time limited. No audit trail or approvals process.

- Something else... ?

Here in europe it is a government database where all the clinics and pharmacies are connected to, so doctor essentially creates a record in the database.

When you visit pharmacy they ask for id and enter your id number system shows them all your active prescriptions and past ones as well, which sometimes helps when your prescription is not renewed for some reason they can give you a week supply while you sort it out.
I ran a couple container-ponds for a year at my old apartment. It was great until the racoons discovered it. They would dig up the bottom and try to eat the fish and shrimp. Otherwise it was a rewarding experience.

I used medaka(ricefish) and a couple airline filters fed with a single air pump run into a splitter to control mosquitoes. I used an aquarium heater for a bit but the electric bill ended up being quite high because it ran too often. You're better off moving the fish inside in the winter if you're in a colder climate. I'm in San Diego and probably could have kept white cloud minnows all year but I was into medaka at the time. I also had a large population of neocaridina shrimp and aquatic snails that I hoped would control algae(they did not).

I got plenty of birds visiting, and the ponds became a favorite watering hole of the local bees. For whatever reason, SoCal bees are not aggressive, so I didn't mind the 20+ bees constantly filling up while standing on my floating plants.

I did end up buying daphnia and moina online since they never colonized the ponds naturally.

I also had a couple "pond jars" to maintain the daphnia/moina population. Those regularly attracted mosquito larvae which ended up as food for the medaka as well as my indoor aquarium fish. I figured the jars were a form of mosquito control since the larvae never reached adulthood.

I initially topped off the ponds with 0ppm, deionized water that I used for my indoor aquarium(I ran a hippie tank with 0 water changes so I needed pure water to top-off). Eventually I switched to using a filter housing filled with "catalytic carbon" which supposedly handles both chlorine and chloramines. I was scooping out enough floating plants regularly to balance the incoming minerals from the tap water used to top it off.

I'd do it again at some point when my daughter is old enough to appreciate it. But next time I'll use some protection against critters digging up things. One nice companion to all of this is a $300 chinese microscope. It's fun to see the pond life under magnification.

The article is super confusing. The anecdote about the drifting meaning of "nonplussed" is interesting, but the way it's framed as an example of mistake related to prefixes just doesn't make sense.

I mean they don't give any evidence of a connection between the "wrong" usage of nonplussed and the "wrong" understanding of "non"?
I'll advice against keycap labels and printing a cheat sheet.
