Yep, you are 100% correct.

This is a very naive bot, it will rarely ever execute at that margin but you will never lose either. You are just betting on the fact that hopefully someone buys out the orderbook by accident or because they really want that asset.

A more realistic margin is 0.0000001% but when you start doing that, you will start losing money so you will want a much better algorithmic trading strategy.

I will probably write a hedging tutorial next.

Intuitively, it would make sense to have a 1/n fraction: you must be one out of n people in the database, right? However, I can think of two counter arguments (correct me if I am wrong).

1) Consider that your date of birth + postcode appears twice in a dataset. Naively, the operator can think to correctly identify you 50% of the time (you are either entry #1 or entry #2). But, it is also possible that you are not actually in the list. Maybe there are two other people in the area with your DoB which are not in the database, thereby reducing the odds of guessing correctly. You have to correct for this sampling bias. Also, the result is now not necessarily in the form of 1/n anymore.

2) Consider that you now have two datasets that together contain the whole population (but there is overlap between the datasets that is difficult / impossible to remove). Your DoB + postcode appears 3 times in the first set and 5 times in the second dataset. Then ask again: what are the odds of identifying you from the 8 candidates? Again, this does not give a solution in the form of 1/n.

Their repair is through IBM. I'm not sure at what point I was talking to Lenovo employees and when I was talking to IBM.

Previous to converting to Lenovo I had two Macbooks. The first Intel white Macbook lasted about a year and a half before dying. I didn't have apple care but when I replaced that with a Macbook Pro I got apple care. That laptop was repaired 8 times, the 9th time it needed to be repaired Apple told me it would cost $800 to replace the motherboard because I had upgraded the hard drive.

Needless to say I swore off Apple's crappy HW and purchased my first Lenovo. That x230 never needed any service. My current X1 only broke because I plugged in a 10 year old $15 off brand external cdrom that fried and pumped 12v from the power adapter into the USB port.

> I don't completely hate Twitter's redesign

For me it's not the design, per se. It's that they changed a couple of things in the UX department that really rile me up.

1- The old design pulled for updates in the background, and the browser tab notified me that there were new tweets in my timeline (which is not a notification for every tweet, it's just letting me know there are new tweets). This doesn't work anymore. I have to open the tab and then it loads new tweets.

2- Every damn day, I have to reset the ordering of tweets to chronological. If I set an opiton I expect it to stay put.

> But these days that doesn’t work because the market is oversaturated. Companies put up a job ad, and within minutes get 100 qualified applicants. They then reject 50% of them right off the bat, and then interview the rest, rejecting anyone who doesn’t completely ace every single interview question. When they’ve rejected 99% of applicants, they’ll offer a job to the last remaining candidate. In that scenario, the applicant has absolutely no leverage.

At first I was going to harp on whether the market was oversaturated or not, but there's an even bigger mistake -- as far as I can tell this situation can increase leverage for prospective employees who make it through the process. If you know that the company just spent 10/100s of hours reviewing, interviewing, and culling lots of applicants, but you made it through their obstacle course and they want to hire you, this means it's very likely a good fit -- that's rare. This would only be bad if the market happened to be saturated with high quality devs, but prices would drop.

This article seems like well-intentioned bad advice -- always negotiate. Analysis of perceived leverage is great, but in the end, if you get an offer you don't think is what your time is worth, then counter it. Politely but firmly ask for compensation in line with what you value your time at like "thanks so much for giving me a chance to join the team -- I'd love to accept the offer but I was really expecting

> The only programmers that have leverage these days are celebrity developers like Linus Torvalds and Guido Van Rossum.

???? This is just plain wrong -- if you are good at your job, you are going to produce a lot of value for a company depending on how they use you -- you don't have to be a celebrity developer to bring value to a company -- you could lack 100% of the technical or leadership skills of either of those people and simply by suggesting "why don't we just use google sheets" and save the company possibly 100s of thousands of dollars (in pricey subscription fees to data platform du jour).

IMO the real problem is information asymmetry -- companies have (obviously) way more information on what they're willing to pay, and not having any data points on what they're willing to pay makes it hard to search for the right companies (to begin with), and negotiate with advantage (at the end).

Sites like levels.fyi and early glassdoor did the most to help engineers reduce their disadvantage when negotiating -- if you want to get better at negotiating, get more information.
Well they are for now. Wait until they get upgraded prematurely too! I should add that "expert systems" were widely touted in promotional materials as being "AI" at the time they were popular, much as "ML" is today.

Yes we're closer, but we are still a million miles away from AGI. Or unregulated self driving cars. Or flying ones.
Yeah it's extremely interesting to think about - it's all a system and when you think you could just spend more money on whatever was available (building a bigger house, horses, arts, hiring staff) you also have to consider that there would have been much tighter upper limits on all of these. The labour market was extremely illiquid, and smaller, and economies of trade and skills were much more localised than today.

Doubtless you could simply waste your money pretty much without limits (pay more unqualified people to do a bad job at building your house, for example) but it would have been much more limited in terms of how you could usefully deploy your wealth, just because there was much less of everything available.
And what ML system in practice will not have some insufficiencies in the training data? The wonderful thing about ML is we won't even know the problems unless we extensively experimentally test the resulting model!
There is. On the diagram I posted above, this is how you reach the "you can be here if you don't do stupid things" point. It's all simple things that you can do better by default by learning a bit about the language, runtime and libraries you use, and by caring at least a little about not being wasteful. They have little to no impact on readability, and arguably yield simpler code at times.

Except for the ongoing war against boys?

I'm fully aware that girls has faced problems as well, probably more than men, but the solution to that shouldn't be to punish young boys today for the sins of their grandparents.

Edit: I'm serious. I'm as much against sexism as anyone, but IMO the solution isn't to make all boys behave more like girls but to make boys behave as better boys.
I started running (very) seriously only recently.

I can tell you for a fact that weight training will not significantly improve aerobic fitness. However, it will improve it up somewhat.

Just an example, you will never run 5km under 20 minutes just by weight training. But you can run 5km on the first try (say.. ~30 minutes) if you are into weight training (so your cardiovascular fitness is okay-ish, it's just not great).

Almost the same exact thing happened to me, as someone in supreme physical shape.

Long story short: you get great results in the things that you directly train; some things overlap, but the overlaps are never significant.
Pretty much this.

Writing code that can handle both old and new schema is admittedly annoying. But it's safe and forces a thoughtful rollout.

Even data mutations can be rolled back. Dual storage writes, snapshots, etc.

The goal isn't to eliminate risk, it's to reduce the risk and make it calculated and bounded. Heck, having a rollback plan that says "we'll restore a snapshot and lose X minutes worth of data mutations" is fine in some cases. It's tradeoffs.

(I've seen a case where literally adding a column caused an outage, because the presence of the column triggered a new code path. Rollback was to delete the column.)
Certainly in the short run ...

It would also reduce the ratio players:console. A personal console stays most of the time off, in a data-center you can increase usage by an order of magnitude. So at the end, even if they buy new hardware every year it would cost less physical resources overall.

In an ideal free market, perhaps, yes. In the real world, people will just move/flee from dry areas.

Yes it is. All that part of the spec says is that it allows implementations to set/have limits on ranges and precision, which is obvious because for example javascript only has 53 bit numbers.

Other implementations can have other limits, but that does not mean that JSON itself or all implementations have the specific limits of javascript.

> As any long time lifter can tell you, putting on muscle mass naturally takes a long time.

I don't agree with this. It's generally easy and straightforward to put mass fast: do hypertrophy, sleep 8+ hours a day, eat 2g protein per kg of body weight. That's all it takes. You'll see results very quickly, even with subpar training.

Learning new motor patterns (especially firing many muscles/full body at once), improving tendon strength, potentially increasing muscle density, improving physical awareness (say, handstand, or anything inverted, or anything with balance, or splits/pancake/perfect shoulder mobility), cardiovascular fitness - all extremely difficult to achieve (compared to just getting muscle mass).
Looking into these things. Thanks for handing me a treasure chest
> The gatekeeping is what kept this specialized for the most part.

It certainly kept the vast majority of retail out, but I disagree that this was the main cause of specialization. I think that the number of lone geniuses who could've beat the market using algo trading is a number approaching zero.

It's true that you don't need a PhD, or even higher education, as the math you need can be entirely self taught. However, you need plenty of specialized knowledge to avoid the accidental discharge of the vast number of very expensive footguns that litter the landscape. This knowledge can be gained from literature, but without having someone streetwise as a guide, it's going to be very difficult to discern genuine insight from wishful thinking.

None of these companies are remotely accountable or fair in their process. None of their rules are democratically decided, there is zero oversight, zero recourse.

Imagine a world where they run stuff. Imagine a world where these companies are in charge of things like currency or things necessary to live.

Legislation needs to recognise the power and responsibility companies like this have, and mandate that those with sufficiently high traction or gravity provide a transparent appeals and dispute process.
They are a way of parameterizing what would otherwise ambient authority.

Rather than needing to pass your file system accessor object, logging object, network interface, database connection provider, etc all the way through your call graph A -> B -> C, you can access those using apparently ambient authority, but still live the code testable, and all without IoC gymnastics.

I don't think the coupling argument is very strong when the effects are encoded in the type system. The kinds of effects that make sense are ambient authority operations which otherwise need explicit parameters. If they're encoded in the type system it's important that higher order functions are parameterized on possible effects to avoid unnecessarily limiting composition.

Of course all this is easier in a language with global type inference, since that will generate appropriately generic signatures that don't needlessly prevent flow of type information.
Agreed, time machine is probably the only hope. Now that we have melted large parts of polar permafrost and the arctic is on fire, "fixing" climate change is not really possible.

What terrible advice. Everyday engineers with a mite of talent have plenty of leverage and should always negotiate. Retaining staff is cost efficient, and real talent is harder to come by than seat fillers.
The great leverager that isn't mentioned or discussed generally is domain knowledge. The company has leverage if the cost of replacing you is low, and if your focus is React or Go or whatever, then the cost of replacing you is the cost of the next programmer who can answer the same interview questions you were asked, or write similar code to what you write.

If your skills also include valuable knowledge in the domain that you work in, or expertise in getting things done in that particular environment (or even in that company) you're well on your way to being priceless. And that pricelessness is what puts things back in your favour.
One of the things I found interesting about The Breakers is that--hot and cold running water notwithstanding--the living quarters were pretty spartan even by middle class standards today. All the bling was in the public rooms.

She's very easy to read, but she's not so easy to understand. There are multiple levels of irony and character insight in all of the books.

You can take them at face value as superficial and nostalgic proto-Harlequins, and a lot of readers do. She practically invented the surly and arrogant romantic hero who actually loves his mother and is kind to children, small animals, and feudal tenants.

But the books are actually blisteringly insightful and perceptive social and psychological commentary, written by a fiercely modern spirit trapped rather unhappily in a superficially elegant but oppressively limiting social scene she both loved and hated.

Most contemporary authors wrote as if they were outside the scene and looking in, so you don't get the same sense of ironic but intimate self-disclosure.

Austen wrote as someone inside and looking out, describing her own perceptions and reactions - many of which are contradictory and complex. So as a writer, she's both sympathetic and uniquely fascinating.

Oversaturation, as typically defined, would result in falling wages, either in absolute or real terms, and that doesn't seem to be the case yet. In fact, the growth in IT salaries is probably among the few that regularly outstrip inflation rates. You have no "oversaturation" until coder rates match more traditional (and really saturated) white-collar jobs like accountancy, where salaries are much lower.

That doesn't mean the job market is not getting more competitive - it might well be, but that does not mean it's oversaturated yet, not even saturated.
