> I've built many systems in this area, but it wasn't until I started working in the Indian market (>10 yrs ago) that it became abundantly clear that trying to calculate the long/shorts signals using historical (/time series) data was a waste of time. (And yet my primary role was to provide tools that did exactly that).

I'm currently working on building similar tools in my area of work for the Indian market and would really appreciate if you could shed some more light into the things you learned from your experience in working in this domain.
The point of type checking isn't so much to prevent bugs in production, but to speed up your development loop by catching many errors before you've even saved your file. Its much faster to see a red squiggly right after you've written a line of code, and fix it, rather than figure out whats gone wrong 10 minutes later looking at a stack trace in your test suite.
> Somebody should sit down and analyze real codebases and understand and quantify how much these projects would be improved by real generics and proper exception handling

And also how most codebases would be worsen.
Am I the only one who sees a different issue here? The problem is neither stateful service over anycast nor TTL based hashing.

Being a DDoS service, one can imagine the need to have stateful POP since each edge needs to track the TCP state in order to provide DOS protection. At the same time, it is understandable that the state can't be replicated at scale.

As for including TTL in hashing algorithm, it is aimed to solve link under-utilization so it is also a valid implementation.

The real bug here is Arista CPE mangling the TTL bits for the Client Hello packets. I always hate it when networking gear meddles with the protocol stack. Sure it gives some flexibility but time and time again, it ends up breaking something somewhere in the path since much of internet networking is a pile of assumptions. Tampering with protocol fields unilaterally is going to break someone's assumptions somewhere down the path.
Thanks both of you ^ for clearing this up. Makes sense now.
I'm in MA (home of $0.20/kWh electricity) and my LEAF gets about 21 miles per dollar of energy. A comparable gas car would get ~13 miles per dollar of gasoline.

I think you're likely still saving money on the electric portion of your driving, as CA rates seem to be slightly lower than MA rates from a cursory Google search.
Why is the weight of concern to you?
If eternalism is real it's hardly fair to say he rediscovered it - all the discoveries have always existed.
> I don't know much about the state of rechargeable battery technology in the late-1800's

This link has some info about rechargeable batteries in the context of electric vehicles. Basically in 1881 key improvements to the original 1859 lead-acid design made batteries practical on board a vehicle at an industrial scale.

https://en.wikipedia.org/wiki/History_of_the_electric_vehicl...

> Credit to that generally goes to Carl Benz, who got his patent in 1886.

The above link reiterates the date of 1884 for a production vehicle by Thomas Parker, two years before the Benz patent.

Also, earlier than that, a tricycle was successfully demoed along a Paris street in April 1881, following a 1867 two-wheeled prototype that did work but wasn't quite drivable for production use.

EVs got a slight head start to ICEs but they subsequently developed alongside each other from the late 19th to early 20th.

The Surface Go is, on that note, a wonderful machine, though I feel one with too many compromises to hit mainstream right now. At 10" it hits the portability of a tablet, while the keyboard is good enough for real usage, not just in a pinch.

The Surface Go 2 will be a thing to watch. If they can get it running on ARM with flawless x86-64 translation, roll the price point down a hundred dollars (or just bundle the keyboard - come on, Microsoft, selling that separately makes _no_ sense here) and ship it with a dongle that turns one USB-c port into 2 usb ports, charging, and a displayport, and what you'll have is a 10" laptop that's fully functional, runs _everything_, trivially integrates into a desktop-like environment for home use, is a passable tablet, and gets all day battery life.

Right now it's _close_ to being able to achieve that, but the battery life is a bit too short and the price a bunch too high, and a switch to ARM could alleviate both of those issues.
So, incidentally, this way of putting the rule provided a nice example of itself.

In the first startup I created, we made ML-based underwriting and credit scoring models for several banks and insurance companies. The results were astonishing. For instance, one insurance company improved its profit by ~70M$/year, thanks to our model (according to our client's report from actual data, not simulation).

But, it was actually tough to sell, because of several factors. 1) The internal risk team did not really like a technology that they could not understand. 2) It was hard to give an explanation of why it would work to the executives.

In the end, we were getting 2-4 big clients per year.

You can check it here, the first ~100 lines are about memory management:

https://www.inf.ethz.ch/personal/wirth/ProjectOberon/Sources...

The exposed procedures (exposed symbols have a star after their name in their declaration) are New (it is treated in a special way by the compiler to remain type safe even if the language itself wouldn't allow it normally), Mark and Scan. It seems that it uses a block allocator that the garbage collector uses itself privately. These procedures use special "GET"and "PUT" procedures which are translated to raw memory access by the compiler (these are also used to access the hardware which is memory mapped). A test for garbage collection is called periodically as seen below (check PROCEDURE GC):

https://www.inf.ethz.ch/personal/wirth/ProjectOberon/Sources...

The collection occurs either when the system is in low memory or some countdown is reached (set by a call to Collect, although looking at the code it seems other bits can change it too).

The rest of the OS just uses the above facilities.
Digital cameras required a huge network - electricity. It's easy to forget, but for most of the history of photography, electricity was not everywhere a camera could go.

And before the digital camera, came the Internet which made it possible for you to show someone the pictures.

Imagine digital cameras of the specs of the first popular wave, but without Internet. Many downsides! The images would be low quality, you'd have to charge the camera, to show someone the images you'd still have to go to the lab for printed pictures.

No, I firmly believe electrical vehicles is about to crush the competition.

Not the OP but the touch screen worked out of the box for me on Arch, Dell 9350 and Gnome, just like on Windows. I don't have pen to test this though.
In the house you just run your natural gas line into a small compressor.. no storing it, just turn it on when you need it. It takes several hours to fill with this setup, but it's not a big inconvenience.

In the car the gas is just stored compressed/liquified in a tank. It takes up a lot of space, so you end up sacrificing some trunk space. Again, just another tradeoff.
> Gmail engineers had to worry so much about Internet Explorer's poor garbage collection algorithm that they'd need to manually hoist string literals out of for loops to avoid GC pauses.

What does this mean in practice? I know about variable hoisting and function scoping, but not about old JS GC algos.
The flip side would be more money available for the institutions that actually create new medicines. I'm not saying it's a better tradeoff, just that it's not so single dimensional.
What's the "premium" that a typical consumer would pay?

Take 15K miles/year at 4 miles/kWh or 30 miles/gal. 3750kWh or 500 gallons of gas.

At MA electric rates, the electricity is $750, the gas is about $1500. It's unlikely that an electric car consumer would pay more than the $750 delta for the electric charging spot, and would likely be willing to pay only a smaller figure because they are unlikely to do all of their charging in that space or network of spaces.

That premium/willingness-to-pay won't even cover the all-in cost of installing a single EVSE in the first year.

I'm curious, what's a better solution for generics if you want some kind of container which doesn't need to care what type it contains? Is the better solution to just use the current C-style void* s everywhere and manually cast your objects to and from void* (or in Go's case, interface{}), leaving type safety to the programmer? Or is the argument that people shouldn't need to write containers, and all necessary container types should be a part of the standard library and impossible to re-implement using regular Go code? Or is code generation a good enough solution? Or are there other, nicer solutions to enable generic container types which can't be abused like Java-style generics can be?

I don't particularly care which direction Go goes in, and don't write a lot of it myself, but I'm very curious what the alternative is.

10 PWh / year (just over 1 TW average) is currently a half-trillion dollar installation cost, assuming $0.23/W PV with a 50% duty cycle.

Yes, this is still an improvement; yes it should be done; it’s just not trivial.

If I do that sort of eating schedule, I'm miserable. Absolutely miserable. I wind up so hungry in the evening that I can't help but to eat. I can't concentrate on things that aren't food. I tend to overeat and on occasion, binge on a lot of food at once. This is especially so when hormones are fluctuating (i'm female). I tend to gain weight eating like this.

It truly isn't worth it.

However, if I eat most of my food later in the day, I'm fine. I skip breakfast. I sometimes eat lunch or a snack - cold food, something like a piece of bread with cheese or something. If I'm a little hungry later, I might eat a few nuts. I eat a hearty dinner, and eat until I'm happily full. Sometimes I have an after dinner snack. I eat chocolate and candy sparingly as I want it. The main change with hormone fluctuations is that I tend to eat more snacks (but less food at dinner). I'm mostly vegetarian with a bit of fish.

Unlike the schedule you describe, I'm not miserable this way. I don't think about food all day and I do not tend to overeat. I can control my weight pretty easily and generally always have being full to look forwards to. Warding off hunger until later is so much different than having to go without until tomorrow.

I understand it probably works well for you: My mother is much the same way with her eating. But folks are wired a bit differently (including their insulin responses to different foods) and adjusting such things makes sense.
>Can any of the places in china even discuss independence in the open? Well, every place in the US can

Only when there's no real prospect of it, and as long as such discussion remains a fringe activity that gets lost in the media noise. Oh, and as long as those discussing it are white, and not e.g. native american, or latinos, and such.

There's a long history, from this:

"In the mid-century, the "Cointelpro program" was a project conducted by the United States Federal Bureau of Investigation (FBI) to surveil, infiltrate, discredit, and disrupt domestic political organizations which it classified as suspect or subversive. The police documented thousands of extensive carpetas (files) concerning individuals of all social groups and ages. Approximately 75,000 persons were listed as under political police surveillance. Historians and critics found that the massive surveillance apparatus was directed primarily against Puerto Rico's independence movement." (wikipedia)

to this: https://en.wikipedia.org/wiki/Wounded_Knee_Massacre

that suggests that they can't really discuss it that openly.

This didn't go down very well either:

Do you really need 16GB of RAM, more storage and a beefy CPU? For reference, I'm using a 12-inch MacBook with a dual-core M3 processor and 8 GB of RAM as my daily driver and it's more than enough; this thing somehow runs IntelliJ and around 5 Docker containers in the background (including Javascript stuff with 1000+ dependencies) and has plenty of resources to spare.

Now I do agree the new MacBooks have a lot of drawbacks (I'm typing this on a keyboard where the "R" key is no longer responding; autocorrect is my saviour) but the time saved not having to tinker with shit in Linux or Windows (and be put to actual, billable work instead) means I can literally buy a new machine every month if needed. Not ideal but for me MacBooks are still the best option at the moment.

My analysis of abuse in social media: it's an unavoidable side-product of buzz mechanics. Buzz exists in social media because the ad-based company that invented it needed a slot-machine-like mechanism to keep users addicted (has already been discussed here recently). As such, for me the root of both buzz and abuse are features like shared global news-feed and real-time trending topics (or network-wide search by some popularity-like criterion in general).

Abuse mostly works in medium to large groups and it crucially depends on dehumanization of the target. Afaik a classical way to unspring abuse IRL is to organize small isolated confrontations, exactly the opposite of doing an epic moral speech in front of the crowd because one cannot have reasonable and logical arguments in a big group. So in the end a global search ranked by recent popularity is exactly the opposite of what is needed for peacemaking: any heated argument will attract more and more bystanders and there is no way to reverse the steam.

So what solution? My guess is that only whitelisting makes sense and with a granularity lower than instances. One could also provide tools for instance moderators to make a particular thread private to isolate it. We should also not provide any popularity based ranking, leaving that to specific structures dedicated to it, with their own rules and a well-defined editorial policy (like hacker news or other). Of course we cannot just stop people from ranking things by popularity, we have to actually make it impossible. One way for that is that links really be directed: retooting something should not inform the target, making the retoot-count a hard edge-reversal problem (which would require full network crawling). We could even make crawling harder by a small rate limiting or proof a work in the query protocol (eg just making the query expensive for the client).

Does this sound sensible?

It's probably not the same sand, or at least not very much of it.
How about if we had a feedback loop between the the continuous integration/delivery system and the dependency version lock file?

It would probably be very difficult to set up, but I imagine it could start by testing the minimal version, and if that works well, then do a binary search to find the latest versions of all dependencies that still work well. In the case of an exception stack trace, it could perhaps find the offensive dependency quickly, but even if not, a brute force binary search should still work.

Futzing around with CAD is the worst. Every time I fire up SketchUp, I can't help but think how much faster it would be to just draw what I need to draw by hand.

I keep doing it because there's definitely value in being able to send drawings around electronically, and eventually, I'll probably need to send something out to be CNC cut.

I've also used both AutoCAD and ProE, neither enough to become truly proficient, but this isn't my first rodeo either.

I haven't regularly eaten breakfast in about 5 years with no ill effects. I never liked eating breakfast (eating the same shitty food every morning kills me) so I just kind of stopped eating it after I moved out of home.

Usually I'll have lunch around 1 PM, then dinner around 7 or 8 PM. I usually don't eat any snacks either. I very rarely feel hungry in the morning, if I do it's because I ate nutritionally empty food like fries for dinner.

Due to a change in life circumstances I'm not currently exercising, but I used to go to the gym just before lunch and never had any negative effects from not eating beforehand, I never felt faint or lacking in energy.

Some days in the weekend I only eat one meal, and sometimes even just don't eat for the whole day. It's not unusual for me to go 40 hours without eating (Saturday dinner to Monday lunch) just because I don't feel like eating.
That doesn’t seem right, I was diagnosed in my early twenties, but the condition was continuing to progress into my thirties.

Probably because you talk about size of population on the level of countries/continents which is clearly irrelevant to the question here (where population of an individual city is what matters, at best).

So not distaste or disagreement, but irrelevance.

If you think "Europe has a smaller population than US" is relevant to whether using public transport where the infrastructure exists is possible for families then you need to state why more clearly.

It's been amazing to watch CS (really the Python community, save statsmodels and patsy) discover statistics. For a while I thought perhaps it was me and statistics that was "behind." Over time I realized that it was mostly re-invention of old ideas: one-hot encoding = dummy variables, neural networks approximating polynomial regression, etc. I decided to double-down on statistics and it's really paid off. NN / random forests and the stats-founded but CS-led approaches are very general models. That leaves statisticians a big opening because a more specific model can be chosen to obtain more accurate predictions. These days I'm positioning myself to clean-up the messes / save broken ML models. Turns out [stats] theory is very practical. :-)
