Summary:

1. Fermat's Little Theorem: if p is prime, then b^p = b (mod p) for all integers b. i.e. b^p - b is always a multiple of p. 8^3-8 = 512-8 = 504 = 168 x 3.

2. Is the inverse true? Does b^n - b = 0 (mod n) mean that n is prime? No. Sometimes n is non-prime (like n=561, divisible by 3). We call these n, Carmichael numbers.

3. Okay, so these numbers exist. How common are they? For primes we know they're common. Bertrand postulated (Chebyshev proved) that for any n>1, there is a prime p between n and 2n. That's cool!

4. Is it true that there is such a bound for these pretend-primes? Well, we have an interesting fact that there are x^(1/3) of them below any x, once we pass a certain point (i.e. there exists an X such that there are x^(1/3) of them below any x > X) so that makes us think it could be true! Worth seeing!

5. But what about this common-ness measure like the B-C result for primes? Well, it turns out that it exists. It ain't as pretty as just between straight integer multiples, but the fact that it exists in some shape at all is cool! That's what this kid proved. Absolutely rollicking fact. https://arxiv.org/abs/2111.06963

Sugar alcohols, also known as polyols, are a type of carbohydrate naturally found in fruits and vegetables (10Trusted Source).

Popular sugar alcohols used as sugar alternatives include erythritol, xylitol, and maltitol.

The bacteria in your mouth don’t ferment sugar alcohols, so they don’t damage your teeth the way that regular sugar does. Plus, they have substantially fewer calories and don’t significantly affect blood sugar levels, making them a smart alternative for those with diabetes (10Trusted Source).

Erythritol contains just 0.2 calories per gram, while xylitol provides 2.4 calories per gram. For reference, sucrose — or table sugar — packs 4 calories per gram (14Trusted Source).

Although sugar alcohols are considered generally safe, some may cause digestive upset when eaten in large amounts.

For example, sorbitol may trigger laxative effects in doses of 20–50 grams, while erythritol may cause stomach upset if you eat over 455 mg per pound (1,000 mg per kg) of body weight (14Trusted Source).

Finally, xylitol is highly toxic to dogs. If you live with a dog, you may want to keep xylitol out of reach or avoid it completely (15Trusted Source).

The company exists for less than 20 years and since then, they have hired 10000s of SWE. Their selection process is heavily biased toward younger people, and so is their performance evaluation process. Their demographic is totally not representative or the workforce, and it's not just a coincidence.

There it is! I am with you 100%. All of these massive plugin systems are a giant time suck. You spend soooo much time just setting things up only to forget the little stuff you need to do when something breaks. Every plugin I have installed requires some level of configuration. The more feature rich plugins (with no surprise there) are basically apps in and of themselves.

I keep hearing praise about this being a simple app, but I found it to be very fiddly if you want more than just markdown rendered in your editor. Lots and lots of time to get things working/configured.

Sync has been a massive PITA for me with Obsidian. Unless you are willing to pay, there is going to be pain there eventually. I had similar problems with OneNote, but those sync problems have mostly disappeared. Further, OneNote's handwriting experience is really good. It is very easy to export all notes from OneNote to Markdown with Pandoc, so while I may be "locked" in, I can "get out" if I want.

Edit: So thank you Obsidian for helping me convert my notes in OneNote to markdown to try you out! I now have a verified escape hatch if I should ever need it. However, I am not sticking around. Too much trouble for little stuff and OneNote is just a really good all arounder.
This has been my experience and I don’t understand it. Technically speaking you have the same capabilities on a zoom call - you can see their face, talk to them, use a virtual whiteboard, etc.

But by the end of it you just feel spent, and the creative energy just isn’t the same as being physically present.

It is implying that the only exotic place you're going to be able to go to indulge that desire is Disneyland, since your kids won't want to go anywhere else.

Not true in reality (speaking as a dad), and there's no way to read this other than as a joke example of a decision tree. Almost an advertisement for how decision trees can fail to capture any truly meaningful turning points of a big decision!
You can, but then none of the Python libraries that expect Python lists can use your Cons as a list.

I tried. It sucks. The conversion becomes a problem all over the place.

Every single official guidance on GDPR that I have seen, such as https://ico.org.uk/for-organisations/guide-to-dp/guide-to-th..., states that I would have conflict of interest serving as DPO because "Basically this means the DPO cannot hold a position within your organization that leads him or her to determine the purposes and the means of the processing of personal data."

A lot of this depends on management, so this can be a good strategy especially for product engineers.

For infrastructure engineers, this is a recipe for disaster which is fantastic because it always explodes in your face which attracts long term thinkers who work well with stake holders to build a long term strategy.

Something I would like to see is an MMO built around the randomizer. There are for example Pokemon hacks that have randomizers so all items, pokemon, etc are in random locations with some guarantee that things are available for the story mode. It helps break up that "follow the guide" mentality. What if you made it so every dungeon was randomized within some degree, so paths are not set, some monsters are harder or weaker. Make it so that "follow the meta" just isn't a thing. Maybe it wouldn't be financially successful in the current market, but it would help replicate that old school experience. But this new mindset of players as seen in WoW classic is what really kills the experience for me. The minmax everything I find boring and doesn't create the felling that games should.

You might want to look into ANS Rewire. Dan Neuffer does an excellent job of covering some of the (speculative) science behind ME/CFS, which is also known as 'post-viral syndrome'. A number of researchers believe long Covid might simply be ME/CFS.

Neuffer's central thesis in ANS Rewire is that CFS is a disorder of the autonomic nervous system. And that's more or less in line with the WHO, which classifies CFS as a disorder of the nervous system generally.

ANS Rewire explains what you're observing with high GI foods too: insulin spikes are interpreted as a stressor by an overreactive ANS and sugar regulation in a CFS body appears to be compromised primarily because cortisol is an insulin suppressant. He recommends dietary modifications of the kind you're pursuing.

Mostly it sounds like you're doing the right stuff already. If you want to recover faster, then there is one strategy that is essential: find ways to quickly and effectively relax yourself every time your nervous system produces an acute response to a stressor (usually in the form of intensified fatigue or brain fog). The most effective for me was to rotate through a large series of relaxing visualizations. So, for example, imagine yourself on a beach in the Bahamas. You do need to rotate visualizations because there's a tendency to become accustomed to any particular one. It sounds absurd, but it does work, so long as you're consistent. Takes about 1-2 months to start noticing major improvements. There's a fairly complete list of relaxation techniques you can try here: https://www.mayoclinic.org/healthy-lifestyle/stress-manageme....

Note that Dan Neuffer's 'REWIRE' technique works along these lines, but he doesn't recommend a visualization strategy, which I found to be far more effective than what he proposes. The principle is consistent though: the nervous system will stop overreacting to stressors if it is retrained out of the pattern. The most effective way to do that is to become deeply relaxed as often as possible throughout the day and especially when you sense that nervous system activation is spiking.

When you emerge from the CFS state, it will happen rather suddenly. There's an excellent description of the recovery pattern here: https://drmyhill.co.uk/wiki/CFS_-_Catastrophe_theory:_why_we.... (Note that the rest of this website is a mixed bag, with a lot of things I wouldn't endorse; that post was written by a guest author)
Too bad we can't design some protocol for applications to "work together" to ensure each has the memory they need. Like some sort of "application collective memory management" where each application has certain memory it needs/wants and depending on the priority of that need and the current priorities of the other applications, it could know to reduce memory usage during those times when some other application has a higher priority. For one, it would help in your case, because background video processing might be a lower priority, or perhaps you want it to finish as fast as possible, so that Firefox and etc. just "freeze" themselves for a while and drop as much memory as is practicable (ie: deleting currently rendered pages from memory and re-rendering them later, or paging those out to disk for a while).
You'd usually look up stuff like that with a shot in the dark into the fuzzy-searching command bar, I believe it's available with ctrl+shift+p? It's been a while since I've used sublime.

Hi Peter.
I have an O-1 for my current startup that expires in 11 months, I'd like to start a new company with a new founder. Looking at the EB-1a vs EB-2 NIW wait times the wait times are in years for the two parts! Do you think it's worth applying for another O-1 instead with the new company? Is it generally easier to get the O-1 second time around? Thanks!

Interestingly this is missing an important piece of context that led to PPP in the first place: A novel worldwide pandemic that was/is killing a lot of people and forced businesses to close — causing an immediate and brutal financial emergency for small businesses in particular.

Small businesses account for roughly 60% of all jobs in the U.S.

Yes, adding processes to reduce fraud would've been helpful in reducing waste, but how do you suppose that should've happened? What kind of infrastructure do we have to means test that many businesses? Could it have happened within a typical pay period or two? How were workers/businesses supposed to eat and pay bills until then?
Great, that's a good one. Yeah, I'm having some trouble splitting time between work and personal life. Thanks.

The federal student loan portfolio currently totals more than $1.6 trillion.

The federal government receives about $70.3 billion in payments for student debt per year[1]. In relation to the 4.4 Trillion in revenue that is about 1.5% of revenue.

What is more meaningful is the total amount forgiven, which is around 300 billion of debt of the students balance sheets, essentially immediately [2]

That is about 7% of the entire federal revenue.

Essentially folks have 70 billion more to spend this year, and also don't need to worry about payments on 300 billion in coming years.

The numbers being thrown around during the pandemic are truly staggering and people don't have the context to judge their size in relation to federal revenue.

For example, the US spent about $11 Trillion on pandemic relief. That was more than 3 times federal revenue in 2020, which was already a trillion dollars over budget.

I’ve been thinking about getting into drones as a hobby (and a way to help manage parts of my sprawling property), but all these privacy stories lately have me spooked.

Is there a “safe” vendor of drones, or has this turned into another “all smart TVs are wiretaps by default” situation that we’re expected to just accept?
You're both right. I know of 10 cases in my social circle.

Two were small tech companies (not startups) that pivoted to WFH services in 2020, had their best years ever, and then returned to their normal work portfolio in 2022. Good years.

Five were restaurants I frequent. Two of those went out of business, two used PPP to pay salaries then laid folks off, and one had a fantastic year because they already had eds+meds+tech clientelle, were in a fairly good pandemic-weathering of the city (lots of SFHs and huge parks), and executed extremely well on the "delivery but we'll keep the social third place vibe going with various virtual events" model.

One is a auto dealership (well, a manager at an auto dealership). Basically used the PPP to pay salespeople salaries for a few months and by the time the first summer came around it was back to business as usual.

The rest were various other small businesses for whom PPP was basically purely supplemental income.

The only one I'm really sour about is a tradesman who did a bunch of under the table cash work (unreported so a 30% boost already) + got PPP + got enhanced unemployment. Almost two straight years of tax fraud. Bought a $300K boat and bunch of other toys this year.

All were forgiven.
I would say it's a good option if you come across an old, exposed roll and what to see what's on it these days, but otherwise, I wouldn't bother either.
I am not sure I agree with the logic. On an absolute instruction count scale grep will often dwarf the instructions necessary for the higher level logic captured in the shell script. Insert appeal to andahls law here. Writing in some more optimal language often requires considerably more work, and if the marginal benefit of reducing a few forks is minuscule compared to grep performance, why would you do this?

Good to be back—Joran from the TigerBeetle team here!

Static allocation does make for some extremely hard guarantees on p100 latency. For example, for a batch of 8191 queries, the performance plot is like Y=10ms, i.e. a flat line.

And memory doesn't increase as throughput increases—it's just another flat line.

I personally find it also to be a fun way of coding, everything is explicit and limits are well-defined.

You dismissed the article and author by labeling it a 'hit piece' by 'someone who hates wikipedia'. When other users asked if you had any substantive critiques of the claims in the article, you responded by saying you don't need to read or respond to the article's claims because of the 'bullshit asymmetry principle' that you adhere to.

The next natural question that I asked is how you arrived at the conclusion that the article/author is heavily biased (or filled with 'bullshit' as you have stated)? You respond by implying what I was asking is 'bullshit', and you don't need to answer any questions about it.

Overall, this thread/tangent has not been constructive. I was responding to your ad hominem on the author and shallow dismissal (which is against HN guidelines) of the article with no supporting arguments/remarks/evidence. Yes, my tone was more direct, as I'm not a fan of shallow dismissals based on ad hominem attacks. Probably my mistake for even engaging given the content of the comments that were posted to others.

Like you have stated a number of times here, you don't need to read/respond to anything you don't want to and you don't owe anybody anything. For future reference, this is just an implied rule in life, and doesn't need to be explicitly stated. Feel free to ignore this comment as you have stated you will, and I definitely don't expect/want anything else out of this conversation.

Regarding your edit: Apple has already shown some power here in negotiation between the big card networks. Apple Card has been on MasterCard since it began, but Apple Cash has "quietly" switched networks presumably as Apple has negotiated lower rates. Apple Cash being a "debit card" is even more affected by the network overheads than credit cards. (Cash was on Discover's Debit network for a bunch of years but is currently on Visa's Debit network. I don't think it has yet been on MasterCard's, despite the Apple Card being home on MasterCard.)

I don't know if Apple alone can fix some of our card transaction overhead, but it is interesting to note that they don't appear to be a passive player either.
