The timezone sign convention is the same as the longitude sign convention: east is positive. The lat/long conventions are documented in ISO 6709, but they predate that standard, though I have not found a good history of it.

Note that these sign conventions are not universal: for example, POSIX has the reverse sign on timezone offsets because west positive was more convenient for american unix developers. There are similar oddities for longitude.

> Yes, a backup tool never deletes by itself, but the standard way of using such tools is that you keep the last n snapshots - this is just delayed sync.

Restic, Kopia and most other modern backup solutions allow you to to define the retention policy. Usually by specifying how many hourly/daily/weekly/monthly/yearly snapshots to keep. They don't just remove all snapshots that are older than n.

They also usually let you restore any given file, from any given snapshot, without having to restore everything. And as long as there's a functional index, this shouldn't be terribly slow either.

i think the main assumption that keybase makes is an important one: you don't need to link a key to a person, you need to link it to an identity. and a github page or a twitter account is an identity. the IRL identity of the person controlling that web identity can be considered out of scope.

if you do need to link a key to an actual non-digital person, then you've got a whole different set of problems.
When this feature is used, they will probably also block dev tools, internet access to most websites and especially remote access. I simply don't see your concerns being of any merit.

On a similar theme, I remember reading a story about a server that would crash mysteriously every couple of weeks. They eventually worked out that this happened whenever there was a new moon or a full moon, and the resulting high tide caused a battleship moored in a nearby harbour to rise just high enough that its powerful radar would interfere with the server.

I suppose it could have been worse. I appreciate that they made the emails very clearly fake. The fact it passed DKIM checks was definitely alarming, though. A lot of people thought there was a flaw in DKIM somehow, but unsurprisingly it's a flaw with the FBI's site.

All in good fun, I suppose.
I purchased a Minolta SLR (35mm) just before digital started to really take off. I had a dozen lenses and was fully invested. I wanted a digital body to come out, but it never did. A few years later, with no digital body in sight, I finally sold all my Minolta gear and bought something digital. A few months later, Sony purchased Minolta and released a digital body. What terrible timing I had trying to get into photography at the time.

Edit: There was a professional digital body, maybe a medium format equivalent, but I couldn’t afford that jump.
DANE + DNSSEC is much, much stronger than our CA system; if you control the keys (let alone if you go all the way and self host your DNS and mail servers), then you cut out pretty much all the intermediaries you reasonably can. You still have to trust DNS at the end of the day.

MTA-STS depends on webpki and the CA system.

Since not everything leverages DNSSEC yet and it's tricky to implement I'd supplement records with something resembling WKD so you have two bands.

Another possibility is having clients fetch keys over both clearnet and an overlay network (e.g. Tor); this doesn't help if the web server is being MitM'd but at least you have to trust client endpoints a bit less.

No matter how hard I try I cannot replicate the exact bubbles of big brands with Sodastream.

Also, unless I want to just make seltzer, I am stuck with their branded syrups that attempt to copy drinks like coke, sprite, dr.pepper and others. They are all terrible and produce soda on par but typically worse than dollar store brands. Combine this with the added cost of doing all this, makes the system uneconomical.

Finally, I know some will have qualms of supporting an Israeli company but this is much worse than that. This company has been mired in controversy for years first for operating a factory on settlement lands, mistreatment of the Palestinian workers, and finally after years of protests in UK and european countries, the closing of the factory and laying off all but 75 Palestinian workers who were then denied a permit to move to the new factory.

There has been so much back and forth that we don't even know the exact truth about what really happened. Some say the workers were treated very well. Others say that the workers feared doing anything to piss off the Israeli bosses who could easily just replace them.

Given that the product itself is not revolutionary it seems better to consider other brands such as Drinkmate.

I tried using a special bottle designed to circumvent their proprietary bottle system (SodaMod) but I found that it does not produce any better bubbles than the OEM sodastream bottles.

My next experiment will be to purchase an alternative system once my Sodastream runs out in the hopes that the mechanism to dispense the CO2 will be better in the new system. Other than that I am all out of ideas to replicate the great bubbles and taste that the OEM brands produce.

It might be easier to define f(m, n, v) where f(m, n, v) is the number of v-vertex shapes that can fit within a m-n square with exactly one vertex in the top left hand corner. Then Q(m, n) = \sum_{i \in m, j \in n} f(m, n, 4). f also lends itself to a much easier recurrence.
They’re all fixed-point. Some are logarithmic, some are linear.

> In which case the output would be in the 8bit range of (0-257) or -127 to +127 if we're using signed values.

The output is 12-bit. 8-bit is simply not good enough. Different internal signals have different widths. From what I understand:

- Phase accumulator is 22 bits (linear)

- Frequency is 14 bits

- Amplitude is 12 bits (logarithmic)

> So assuming I want to represent a signal value of 127 (i.e. sin(t) = 127) using base 2 logs, I punch this into my calculator and i get log2(127) = 6.9886. But that's not what's going to be stored in the signal LUT since it's a floating point number.

sin(t) never equals 127. The highest value it will ever reach is 1.0. Instead of punching in log2(127), punch in log2(1.0). From what I understand, the values have 8 fractional bits. So if code value N represents a signal level of 1.00, then code value N-1 represents a signal level of 0.997.

The synthesizer has two main lookup tables: one maps phase to log-sin, the other maps log to linear. Even with an incomplete understanding of how the chips work, it is believed that these widths are correct or very close.
Yes I see that will be a sticking point
> So server side security is in this case better because it's a more clean solution?

Yes, absolutely. There's nothing a client can do if the server doesn't send it the answers.

> In this case the cleanliness of the solution is irrelevant as long as it works.

*NO!!* How good a solution is always matters! Another solution to students cheating is for an older student to stand over them as the take the test, and beat them with a stick if they try to view the source of the test. That' would be a solution to this problem, but it's so obviously bad. But hey, it'd work. It'd actually work better than this because it would work on every test, on every site, in every browser, for every computer... Because how clean a solution is doesn't matter, who cares if there's a little blood on the screen?

> Students can always sneak in attach a keylogger to the teacher's keyboard and read out the password for accessing all tests. It's about erecting a barrier that is good enough.

If a student is able to sneak a keylogger onto the computer of a teacher without getting caught, they're smart enough that the test is pointless to them.
> A lot of people dismissed the web in the 90s too. There can be a bubble and a crash, but still be underlying tech there that will have a big impact.

Yes, I always think of Google in that way. They just powered through the dot com crash by being really useful.

I'm sure there are examples of this in crypto.

LaTeX specifically might be bug free, but it's so incomprehensible to a not very experienced user (like me) that it exactly matches the notion of "software where you need support". the only good thing is that you can often get the support for free on the internet. Even though it might be stable and bug free, I'm just avoiding it for "shinier" things like HTML and Ctrl+P in a browser...

What is your thought process when doing sound design with FM? I've been doing this for years and while I can easily wrap my head around subtractive synths and go from sound-in-head to sound-on-tape pretty well, FM is just impenetrable to me.

Are there any good tutorials on how to approach this?
I'm also confused by this, does it get set a reference point once? If so what is the accuracy degradation, is it fixed over time or acceleration?

If it's updated periodically what does that system look like? Is the advantage that it can manage on its own "offline" for a usable period, unlike GPS which needs an active connection?
Basically (I don't understand this satisfactorily either) : represent meta concepts of the object system inside the object system itself.

As always, the best way to make sense of it is with an example. One example is meta classes in python. Classes, those 'blueprints' that we create objects in their image? they are themselves but objects, their class is called 'type', it's a special kind class, a meta class (a class whose objects are themselves classes).

You can inherit this type and create your own meta class, and that lets you do various cool things. For one thing, object creation in python is done by calling the object' s class as if it's a function. Now this is a method call (__call__), where do methods reside? in the class off course. So for classes, the __call__ reside in the meta class. When python says you can inherit this class, you listen very carefully. This means you can inject arbitary code during the instance creation process. Now every class that is an instance of your meta class can email you whenever somebody wants to create an object from it. It's like the interpreter is giving you a hook to something incredibly intimate and private to the VM, exposing it from within the interpreted language itself (and not as a C API for example)

meta classes is a kind of MOP for python because it represents intimate details about an object system ('hey, what exactly happens when we ask a class for an object?') inside that object system itself ('it calls this particular method, which you are more than welcome to override and augment as you please without leaving the comfort of the language').
Nope. Especially when switching from a phone with a SD card to one without.

Analog has a lot of detail that digital doesn't. Real circuits are imperfect in all kinds of interesting ways. It's not just randomness, it's specific kinds of non-ideal operation - distortion, non-linearity, noise distributions, and other fine details.

It's trivially easy to make idealised digital models of VCO-VCF-VCA but they sound sterile and boring. The more imperfections you model the richer and more interesting the sound get, but the more processing power you need.

Good models - especially good models of analog filters - are incredibly difficult to design. And even the best aren't as smooth as the real thing, because - for example - with a filter you may have to recalculate a load of coefficients for every sample.

A lot of digital models get in the ballpark now, but very few do better than that. And there's a fair amount of secrecy among DSP coders. There's no mystery about the basics, but the manufacturers like to keep the best models to themselves. So the big computer music tools - like Csound and Supercollider - have third or fourth rate models that are a good few generations behind the latest code.

So it's still hard to get comparable sounds of pure digital synthesis. The new M1 chips are fast enough for better models, but you'd need about 5X to 50X the processing power - and more research - for no-compromise digital replacements of vintage analog hardware.

I don't think holding wargames in class would make them boring because of that. I would've enjoyed such a thing. For normal classes some kind of "hacking adventure" where using view source and other tricks to move forward is necessary I also don't see any boring faces. The teacher who sells this stuff to the children is key here. This is why teachers should have as much time for preparation as possible. At best this preparation would be like preparation of an actor (with extensive knowledge of the plot), because everything else is already at hand (just my idea of what teachers should be).
So they why don't they consider a PoS option like Solana? That is like me complaining about an entire race because one or two people did something negative to me that were of a specific race. It is stereotyping which wouldn't be appropriate in other scenarios.
> The thing that worries me about this kind of thinking is that, while it's technically correct, privatizing education, or treating it as a competitive market, gives you bad outcomes. The rich can afford to send their kids to the best schools, which keeps the rich families rich. The poor can only afford to send their kids to the worst schools, or the chronically-underfunded public schools, and this keeps the poor families poor.

Who runs the schools is a separate question than who pays for the schools. You can have the government provide school vouchers to everyone without having the government operate any/all of the schools.

The existing system is what gives you the thing you oppose. The rich can afford to pay for private schools no matter what, but the middle class can't both pay property taxes to fund public schools and also pay for private schools. The poor can't even afford to live in the neighborhood that allows them to attend the middle class public schools.

Give everyone a voucher and the poor kids can go to the better schools because getting accepted into a particular school has nothing to do with the price of your house.

Of course, the really market-based solution is to give parents cash rather than vouchers. Because maybe you want to home school and spend the money on books or field trips rather than a prepackaged education bureaucracy, or pay one of the parents for their time in teaching the child themselves, and why should only the rich kids have access to that?
