Thanks so much for taking time to answer these.

As a fellow founder/eng in the digital consumer privacy space, I can tell you that it remains fringe. And it isn't clear if it will take off in an exponential way anytime soon as, from what I have noticed, VC-backed startups in this space trying to pry out growth have indeed struggled (SilentCircle, as one example). Competing with free [0], as it turns out, may make for a decent-sized lifestyle business, but may not bring in VC-warranted returns (Netflix vs BitTorrent / Spotify vs LimeWire notwithstanding).

Enterprise security and privacy remains very lucrative however, if you are considering pivots :)

Please consider getting ente.io's cryptography reviewed by cryptographers. It does not inspire confidence so much so that I feel ente.io frontends are better used with a tarsnap backend.

Thanks again.

> I'm confused when people don't use it for bigger systems. I like that the compiler detects most of my errors before I run the program.

That is more likely due to the type system than manual memory management. People after all say the same thing about Haskell, which also has powerful types, but is garbage collected.

There are two kinds of code errors to worry about: wrong answers (2+2=5), and divergence (a fancy name for crashing, i.e. 2+2=segmentation fault). In a jet engine controller, wrong answers and segfaults both potentially cause fatalities, so you better not use GC. Ada is made for that.

In (say) a compiler, bugs leading to wrong answers (incorrect code emitted) might cause potential fatalities, but if the compiler segfaults from running out of memory, that's only annoying (the developer must find a workaround, use a bigger computer, or whatever). So it is fine to write a compiler in a GC'd language even if its memory footprint and timing characteristics are hard to verify. If you wrote a compiler in Ada you'd spend a bunch of time with manual memory management, for little benefit.

In fact the most serious formally verified compiler (compcert.inria.fr) is written in Coq, which you can think of as an ultra precise dialect of OCaml and which is GC'd (Coq in this case generates OCaml code that uses the OCaml runtime. It can also generate Haskell etc.).
Definitely true - usually you don't have a choice though due to vesting schedules and/or illiquid markets pre IPO.
His comment wasn't limited to "fairfax county", it's true of all situations. For example noone minds black overrepresentation in basketball and proposes limiting them over there.
> I divide the sphere into individual iron atoms.

You have highly restricted the act of choosing sets of points here. B-T doesn't say that any "division" results in that unintuitive outcome.

Note that points are infinitesimally small and infinitely many, and atoms in your iron sphere are neither.

For a text file? Why?? Wouldn't the worst case be the size of the file?
question:

How far out can a planet be if it has a roughly circular orbit? At some point outwards neighboring heavy things will make it unstable.
Thanks for informarion! This is actually cool if it works well.
Some cities had an issue to even have to ban in person businesses from banning cash transactionss. Given the costs of cash handling taken for granted bizzarely it is possible that being charged a fee where there was none before will save merchants and consumers money net even while the credit card companies make money. Cash counting machines, time spent tracking physical money, safes, and armored car transports all cost money. The wire transfers of money and credit are a real service of real value.
I don't think that you did anything wrong... it is HN's algo that is wrong.
US has bad commutes because of our terrible land use. So yes people should let go of homeownership fantasies, but also we simply cannot fix land use with individual actions alone.
The Paris metro's noise does not compare with the incredible screeching of the BART.
Also, I think the Paris metro has special requirements, including quite sharp turns which I'm not sure trains can handle. Some of the lines in Paris actually use tires with side rails to channel the train to handle this.

Kinda annoying that it asks me if I want to view the "US site" but still shows the London Underground and UK graphics even though they have NY, MA, CA, BART and other gfx appropriate for US.

If they're not going to personalize it, why claim there is a "US Site?"
Cruise ships are back, and the business is booming with some fully booked ships.

Vaccine passports and require a PCR plus quick test before departure for all crew and passengers should do the trick.

Slippers does look interesting - not sure I like the idea of declaring components in a YAML file but otherwise it seems to address the pain points of components. Would be interesting to see how well it integrates with Django forms.

I guess Jinja macros are also pretty good as a basis for building components as well, but I've always found switching to Jinja 2 in a Django project to be too much hassle to be worth it.
It’s about the Backblaze having your private key, “irregardlessly” of how secured they got yours.

Yes - TMI could have been an outlier but once it shaped public sentiment with little counter argument it’s become increasingly hard to go back. Regardless of whether or not nuclear would be functionally useful, I don’t think it’s productive to talk about it without focusing on the “… and here’s how any of this will actually reach production” discussion after decades of plans stalling or being cancelled.

I don’t think everyone pushing it are motivated simply by its use as a distraction by the fossil fuel lobbyists but there’s definitely a tendency to focus on the engineering side rather than the hard but necessary approvals.

> If you can fit a 4G antenna in a phone you can easily fit one for iridium

The frequency isn’t the issue, it’s the distance it needs to transmit. Increased output power/longer distance needs a bigger antenna. Iridium / Starlink / other LEO satellites are >300 miles above the earth. Your smartphone doesn’t have even remotely enough power to transmit that far, good luck getting even 1/10th that distance for even a very shaky connection.

As a concrete example, your phone’s cell radio transmits at 100-200mW into an antenna which has minimal additional gain. Iridium / Inmarsat phones transmit at around 10W into a higher gain and significantly larger antenna. That’s two orders of magnitude more EIRP in the end.

Apple might be able to do an emergency beacon like transmission from an iPhone into LEO, but assuredly can not do a continuous transmission like in a phone call, even at very poor audio quality, without a relatively massive change in phone dimensions.
The people I want to talk to are on facebook groups (my hobbies seem to be "old people" hobbies). I think you're suffering from network effects.

Sooooo..... StackOverflow solved it by starting with a vertical the founders had a lot of social juice in, and spreading in to other verticals. Possibly also by focusing very tightly on "questions and answers".

So my suggestion is "overfocus". If the big platforms have a weakness, it's that they're generic one-size-fits-all solutions. Solve one problem (Q&A, show off my project, discussion, news aggregator) for one vertical really well, then expand. An example off the top of my head might be collaborative note-taking for a class. 6510's "write a book in public" platform is also a fantastic idea at first glance.

(But skip the distributed bit - customers don't care about your architecture, and whatever USP a distributed platform has can be emulated by a centralised platform. Centralised always wins).
What is the distribution (relative to galactic center) of TNOs used for calculation?
This doesn’t, however, make sense because Stitch Fix’s core hours cause entirely too many employees to be on the server at one time. Last week, the server went down at exactly 8 am every single day because it was the first hour stylist were allowed to be on. It also went down for 3 hours on Wednesday. Stitch Fix is not equipped to have this many employees on the server during these core hours. If the server goes down, you are to move your hours or take a pay cut— whether you are part time or full time. This is exactly what stylists saw coming, so they bowed out.
I think Discord is then modern form of this. It’s really a great product.
The problem - correct string matching at scale. I am aware of fuzzy string matching. The problem is that the two strings can be > 90% similar even if the difference is, for example, one digit in the year of manufacturing. My current solution is to represent the 2 strings as similar as I can based on the available information by transforming (wrangling) the data to match the data as close as possible and then applying constraints based on make, model and year (they should be the same). It works pretty well, but I am looking for a more interactive (human-in-the-loop) solution.
Test prep barely works, the entire field of psychometry is dedicated to this topic. How about looking into actual science instead of writing nonsense to justify your racism.

Sort of. GPU "cores" in the CPU space would be called SIMD lanes. Apples to apples GPU cores using the CPU terminology would put an Nvidia 3060 at 28 cores and a 3090 at 82 cores.
Even just a few years back, some top-rated corporate bonds (e.g. Microsoft) weren't a bad investment--although equities of course ended up doing much better. These days? I'm not sure there's anything that's not one step away from putting money under the mattress that makes sense outside of equities.
No pictures and nothing but memory to document this one, but I'll tell the story:

The guys at the construction company's shop (hackers of metal, all of them) had caught a wrecked up Suzuki high end motorcycle with a 1500cc engine (iirc) and some wild transmission they were all excited about. So they grabbed a little child's go-cart of the scrap metal pile (the 5hp lawnmower engine it was supposed to sport had long ago gone to other uses), weld on a layer of reinforcements, and put their new engine on this cart that weighs nothing.

First test shredded the tires, so they listened to the guy who did the math on gear ratios and sourced some high speed aircraft tires for the next trial. and put a roll bar and a couple of front bars on as a "crash cage". That one ran.

The only way we had to test the speed was to run it on the highway and follow along in a car; and no one had a car that they were happy doing over 110mph on that road with. So we knew it went faster than that but we never had any documentation of how much faster it was.

I was the only person stupid enough to drive it on those runs, I guess 130mph tops; after we put the plexiglass on it. Never got it out of 3rd gear. It had 6.

True.

Overassessment of general literacy (the reading kind, not computer or maths literacy) is exceedingly common in technical fields. Averag computer skills are abysmal.

About 5% of computer users have "advanced" literacy, defined as "Some navigation across pages and applications is required to solve the problem. The use of tools (e.g. a sort function) is required to make progress towards the solution. The task may involve multiple steps and operators. The goal of the problem may have to be defined by the respondent, and the criteria to be met may or may not be explicit"

Scheduling a meeting room, or determining "what percentage of the emails sent by John Smith last month were about sustainability" are examples of level-3 tasks.

A quarter of the adult population cannot use computers at all, 14% are at "below level-1" skills, and 30% can only perform very basic level-1 tasks, for a total of 70% of the population which has only very basic skills ... or less.

It's easy to over-estimate the general literacy and numeracy of the population, especially if you yourself are college-educated and work in and/or with information technology.

The United States performs one of the most comprehensive assessments of adult literacy. *The key lesson for me is just how limited it is.*

https://nces.ed.gov/pubs2019/2019179/index.asp

The findings correspond highly to a study of adult computer literacy amongst 20 countries by the OECD:

"Skills Matter: Further Results from the Survey of Adult Skills"
http://dx.doi.org/10.1787/9789264258051-en

Computer usability expert Jacob Nielsen has a discussion of this as well: https://www.nngroup.com/articles/computer-skill-levels/

I've discussed this as "The Tyranny of the Minimum Viable User", which both notes that much of the population has very basic skills, and that this also hampers the very small minority who do.

No, but they do have control over people and property.
No place in a pizzabox for that.
Some options:

- contracting/consulting - quite often no on-call duty as it is tricky to bill,

- working on software for brick&mortar businesses, such who usually overlap with your work hours,

- working in R&D area where you don't touch prod, where there is a dedicated team who does the integration, deployment and prod support - often quite popular in big organizations with long release cycles etc.
You can index on fields in JSONB, but I don’t believe that’s what the op is solving for here.

In either scenario, I’d still generally encourage avoiding storing JSON(B) unless there isn’t a better alternative. There are a lot of maintenance, size, I/O, and validation disadvantages to using JSON in the DB.
I think this is more likely incorrectly understood leaks. Similar to what occurred with the Nintendo Switch OLED. My guess is the chips and whatnot the iPhone will use will support this but Apple won’t enable it in the software.

I believe this is equivalent to fm radio capabilities in some of the iPhone chips
I worked in forums for 4 years. It is the worst most unprofitable business you can get into. The best you can do is show low quality ads or use crappy affiliate programs. The more ads used the less the users like the forum. Forum users love being anonymous. So you provide no value to advertisers that want age,sex,location. Advertisers also HATE forums due to their ad being shown on user generated content. Drama: There are always personal attacks on moderators, posting of illegal material, threats, police involvement and constant human curation. If you build centralized forum software every forum owner works day and night to use something cheaper and get away from your control. Don't even bother offering host your own software (non centralized). "OH i know React I can build a vBulletin clone." No. No you cannot. vBulletin has been working on this software for 20 years and they offer it for $300.
I wonder if it would someday be possible to build and epic rail tunnel between them, by way of Okinawa or something.

If this block is the thessalacracy or whatever, increasingly long rail tunnels—be they Switzerland–Italy, Ireland–Britain, Chile–Argentina, or whatever else—would be my preferred foundation for international relations.
The algo literally gives 10 cargo jackets in the summer because they are “high match scores”.
They just announced a new large format product, starting with California. Initially it'll show rain but soon they will support many data layers as well as pushing data via API. I bought one in the hopes of displaying fire data.
For one thing, I said phone as did GP I was replying too. That’s not a phone (aka needing a continuous real time connection), that’s a low bandwidth data transmitter (aka a best effort single transmission that can take multiple minutes to send). Even still, look at the size of the antenna on that. It’s definitely not all plastic there. If you’ve ever seen a tear down of a modern smart phone, you’ll realize 95% of the space is either battery or screen. The space used by antenna (which is often part of the outer metal ring) or circuit board is extremely small in comparison.
Ditto, I have the BART one and its fantastic!
The OpenSSL RSA private key contains all the elements needed to recreate the public key from it. [0] Explains it in more detail.

You create the private key on the client side so that you can encrypt it with a custom password before sending it to Backblaze. Doing this makes they key recoverable from you - as long as you remember the passphrase to decrypt it - and unusable from Backblaze.

Agree. I've also tried Jinja macros and despite I was satisfied with that, it feels a lot like you're moving away from the core of dj ago. Suddenly translations don't work.and you need other solutions, templatetags don't work, and most third party libraries are built for Django templates, not Jinja. Definitely not worth it.

Just take a look at the egress pricing of B2 (10USD/TB) S3 (92 USD/TB) and then look at Hetzner's 1 EUR / TB. There is quite a margin there - same thing with the storage costs (23,5,1.5).
As much as I like apple / iCloud / my iPhone, I do like the idea of seeing all the places on a map that I’ve traveled with my lovely wife Emily. We’re hoping to go to the Seychelles if the next three months work out at my contract gig.

I like the idea of being able to type “water” and see a bunch of water bottles mixed in with all the water-y places we’ve visited.

What sealed the deal was to see it on a map. I typed “water” into Photos just now, and it did a pretty good job. But there’s something peculiar about being able to look at a pin and say “I’ve been at that pin.”

Just a silly thing. But it costs me nothing to get it, so I want it.

Well, it really depends on the computational intensity your algorithm needs. I've stumbled upon things of beauty porting things to GPUs, especially if you're going to perform huge amount of operations based on a very small amount of data. As long as you don't have too much intermediate data, register spilling, etc. these GPU things do fly. They're also very impressive on NN-based workloads... Even something 2 or 3 gens behind can be game changing, with some optimization effort. Tensor libraries leave a lot on the floor to pick up, especially if you're not using the canned 'competition winning' networks.
The precision is probably on the order of the Iridium spot beam size, which as far as I know is 300 km.

As to why: Indian customs officers confiscating all iPhones is probably bad for business (in the long term).

Now, but I expect it was a lot more common in the early days of the Intel transition.
They don't say where they are making them (mainly China or ex-China) but a device like that with discrete components is going to cost basically what they charge. An amateur could make one with a considerably smaller bill-of-materials, but then you are paying $0.00 for their time.

This is how discrete electronics vs ICs is like a model rocket vs a moon rocket. The methods that are used to assemble panels for TVs and phones are astronomically more economical than laying out a hundred or so LEDs on a circuit board.
Microsoft isn't helped by the fact that there are also FB and Google in town, and they pay at least 20% more and have better engineers to work with as well, which makes work far less aggravating. So MS gets FB/Google rejects at this point, and there's a constant brain drain on top of that. But their internal culture has always been, "if we pay managers well enough things will work out". This breaks down when you actually have to do something hard (rather than rearrange buttons on Office app toolbars), as managers aren't the ones who do the actual work.
Almost anything when done at the fine edge of engineering for optimum price point without sacrificing reliability is going to be an amazing thing to do a deep dive in. Windmills are another, they seem so simple and obvious until you dig in.

When and how are you planning to change your Terms of Use / Privacy Policy? That kind of information should be in the documents. Your privacy policy is currently insufficient.

Okay, but what information do you collect? “Your information” is too broad; if you're collecting my retinal scans or matching me to a behavioural analytics profile, you need to justify it. If you're not (which you're not), say so!

> You can delete your account and all your data at any time (see Profile).

But can I take all my data out? Currently, no; that's not a GDPR violation, so long as you provide it on request, but it's certainly a feature I like to have!

The 30-day deletion threshold for anonymous accounts is (IANALaTINLA) GDPR-compliant, since you have to delete personal information (on request) within 30 days, and that happens even if you can't figure out whose account details you should be deleting. Good job.
