I have done codility tests in the past (with another company) and I would say that its the worst way to interview someone. You need to code your solution to accuracy in the defined time and pass all test cases. Its not that the problems are super hard, but the fact that the company is not interested in understanding how I solve problems and does not have time to interview me is a huge turn off.
The biggest problem is that Avid Life Media has done jack squat in response to the data leak. They've not communicated any kind of risk mitigation strategy. They've not allowed users to change their compromised passwords. They've not made any efforts to contact affected users.

This is like a rape victim not only trying to pretend the whole thing didn't happen, but all the while knowing that her attacker had HIV, has good reason to believe she's seroconverted, and is still having unprotected sex with her regular partners without telling them anything.

While the company is a victim here, their actions are themselves criminally wrong.

A) Purely subjective opinion. Actually a study published in The Journal of Sexual Medicine in Sept 2014 (IIRC), sought to define what true sexual deviation was. The results found that many things considered sexual deviations in popular culture are actually not that un-common in reality.

C) The fact that this is true doesn't make it good or bad. One person's nightmare, is another's acceptable risk, is another's pleasure.

The long term efficacy of dieting is low, and that should be totally unsurprising: the very name implies temporariness. If the overweight wish to lose fat, a diet will work. If they wish to keep it off, they must make permanent diet and behavioral modifications, which is not what a diet is. Fewer calories and less sugar/carbs/highly processed foods does work, but it must be permanent.

People want a pill that you just pop once a day without any changes in behavior. And the vast majority of people complaining they can't lose weight don't prioritize losing weight over their current behaviors: diet composition, sedentary lifestyles, etc.
On the contrary, much of the motivation for this is writing stuff like image decoding libraries in Rust. People often decode untrusted images, so it makes sense to use a memory-safe language to isolate crashes and prevent RCE vulnerabilities without the overhead of spawning a process per image. But image decoding makes great use of SIMD, so not having SIMD in the implementation language will result in a performance regression over the state of the art.

And even then I still see it as wasted time. I agree with OP. I don't see an IBM school being valued in the same way traditional colleges/universities are. It's like the MCSE all over again. My general advice, don't waste time/money on any kind of certification/degree that is provided by a for-profit company unless you _really_ know what you're doing. e.g., SAP Certification when you're already working as an SAP consultant/employee making 6 figures.

The big ones are all in stock and that has some issues:

There will be tax event when they cash out. You'd be
surprised how many people take short term capital gains

do that until you can sell. And then you have to wait a
year for the long term capital gains tax rate and what if
the stock crashes?

tl;dr: $50M in stock is probably around $25M in cash.

You enter the turn with the steering wheel. Once setup you control the turn with throttle (or braking) and how the car behaves is related to, among other factors, mass balance.

To be clear, people talk about "weight transfer". That is not what happens at all. Weight transfer would require masses within the vehicle to move. What does happen is that the resultant vector of all force vectors acting on the vehicle shifts to have a forward or rearward component depending on what the car might be doing. At a basic level it's about good-old F = ma. There is no weight transfer in the strictest sense (unless you have a super loose suspension with four feet of travel or a partially filled fuel tank).

So, in a very direct sense, driving is about manipulating force vector directions and magnitudes through acceleration (the physics kind, meaning in any direction).

Accelerating through a turn does not shift weigh to the rear. No significant mass transfer takes place while accelerating or braking. We say "weight shift" because that's the way it feels to the driver, but this is not what's happening.

When accelerating forward during a turn you are increasing the force vector at the point where the tire contacts the road. This results in increasing forward velocity around the path the car is travelling. Since centrifugal force is proportional to the SQUARE of tangential velocity a mass imbalance to the front or rear can have a very different effect on car dynamics.

A rear-biased Porsche 911, on deceleration around a curve will be subjected to a torque about the center of mass that has the rear end pulled towards the center of the travel arc. A car that is front-biased will do the opposite, the resultant torque will pull the front towards the center of the arc being negotiated.

Because of the square relationship to tangential velocity and the "unusual" dynamics of a rear-biased 911 people who do not understand the physics involved get into real trouble while negotiating turns at speed. If you decelerate quickly this square-of-the-velocity related torque about the center of mass will spin you in a microsecond.

Of course, there's a lot more to it, such as suspension geometry and tire patch dynamics, yet the fundamental physics are not that complex and can have major effects on what a car does during high performance driving.

The throttle is a major influence in turning because of it controls acceleration and it's relationship to dynamic forces is proportional to the square of velocity.

EDIT: Corrected friggin iPad-induced typos.

Also, to complete the story: When you exit the turn you exit with the throttle first and then the steering wheel. In other words, on a front-biased vehicle you can start to feed-in throttle somewhere past the apex to use the square-of-velocity torque relationship to start to carefully straighten your motion path while not really moving the wheel. At a certain point you start to release steering pressure to smoothly transition into a straight path. If all of this is done smoothly it feels amazing.
Literally no one in this thread has been calling for these TOOLS to be outlawed: that's entirely your straw man. However, I 100% through and through believe that they should be disable by default and enabled only by those specific parents who want them.

In another comment, you say that I had to enable these TOOLS. That is factually incorrect. I do not want to use them and did not enable them when initially setting my son's Windows 8 laptop. I did not enable them when upgrading to Windows 8.1. I did not enable them when upgrading to Windows 10, but received the spy report the next business day after performing the upgrade.

These TOOLS are on by default, until you explicitly disable them. I am not calling for them to be outlawed. I'm calling for them to be turned off unless and until parents personally and explicitly choose to turn them on.
Ask HN: Building an aggregator by scrapping data from web pages
Hi,

(newbie, apologies if not right place to ask)
I would like to build a niche aggregator portal by scraping products on sellers webpages. I am not sure if there are any existing apis provided on sellers pages. So my question is --
a) What should be my approach to achieve this. (Using Technology tools or cold calling to collect data.) Second approach doesnot look scalable.
b) What kind of revenue streams can be achieved. For eg: I know I can put banner ads once there is traction to the site. But I am looking for companies to pay for listing or promoting, than banner ads. Ideally I would even like to get commissions for bringing customers to sellers websites or even making a sell.

Looking forward to your answers.

Predicting market crashes is like predicting the end of the world.

When it actually happens (in both cases), there will be some subset of people whose published prediction is close to or even exactly matches the date when it finally did happen, and those people will gloat about it.

But for every one of those people there are thousands, possibly millions or more others whose prediction dates came and went with no catastrophe occurring. Given the huge number of people who publish their predictions, then, we have to ask which of these is more likely:

1. The people who got the date right -- either exact, or within a certain small window of the actual date -- had some genuinely deep insight missed by others, which allowed them and only them to make a correct prediction, or

2. Given a large enough segment of people making predictions, some subset of them will have their predicted date match the actual date purely by chance. For example, predicting market trends five years out only gives five years in which something can happen, or twenty quarters, or sixty months, or 260 weeks, or 1,826 days to peg your predictions onto. If the number of people making predictions is large enough, all dates are likely be covered by at least one prediction.
Unfortunately I don't have the reports handy but one of things is that they achieve outcomes similar to private health systems given much less money per capita.

Outcomes do take into account the starting conditions ("comorbidities") so this doesn't necessarily mean that the actual health of that population is better than average population. Because as you pointed out, service people get a pretty raw deal when it comes to occupational hazard. ;(

My oldest daughter is 6. I introduced her to programming by letting her type in a full-screen emacs buffer with large letters. We'd change the colors, make a "rainstorm" or "snowstorm" (fill the screen with '/' or '*'), type words together, etc., and for a while she had a notebook with commands like "M-x set-foreground-color" listed in it.

My youngest daughter prefers to rip the keys off my laptop, so she gets to do less typing....

But no. I'm still bitter that this seemingly obvious concept seems to be so thoroughly precluded at very basic levels.

Start by doing none of the above, but simply measuring the intestines, and recording the data, along with all the things you mentioned above. Statistical analyses can be done after, to see if there's anything interesting in the data at all.

Not sure how to address the tension question; I guess ideally, you'd have someone fly around to Japan and a few other countries, and demonstrate some arbitrary method of measurement. But that starts to get expensive.

Your nine words aren't any more expressive than my two, and that's the problem. There's not much value in being able to express simple commands with long sentences (with often many interpretable meanings)

There _could be_ value in natural language processing for some very complicated commands, but it would have to be fairly intelligent before it would be useful.

If you treat the indices as between elements and include all elements that are between the start and end elements, there is only one reasonable choice. It would be more "special" to include elements that are outside of the specified range (i.e., the element to the right of the final index).

So you're admitting that it's on by default in that scenario. Which scenario did you imagine I was referring to?

This is a horrible, terrible, unreasonable default setting. Also consider that the same mechanisms that make it possible for you to spy on your kid could make it possible for your significant other, employer, or any other interested party to do the same against you.

Yeah, I just meant for the nostalgia. As in, I don't usually use command line on my Mac but Linux more or less necessitates command line use at various points.
Sometimes; other times math desperately wants indexes to start at 0 for the same "offset" reasons, to avoid having to add one. If you're using indexes as subscripts, some formulas start subscripting at 0. If you're building a series, many series start indexing at 0, not least of which because you often want the first term to involve a 0 in the exponent to make a constant term. Polynomial powers start at 0. 0 is a more common bound for integrals than 1. Angles start at 0. Physics values start at 0.

If anything, mathematics provides as much of a reason as pointer arithmetic to start indexing at 0. Indexing from 1 occurs more if you're creating a one-to-one correspondence with some real-world object, and you want to number those objects starting from 1, perhaps because that's a convenient user-visible numbering.
