A cache miss isn't noticeable by a human. Code that cache misses a lot runs 10-100x slower than code that takes into consideration that it's running on a physical machine and not an abstraction. That is very noticeable by humans. Even when your data structures and algos are designed with a nice O(logN), it's very noticeable when one program bogs down with 1/6 the data compared to another.

I work in games, so the story I tell new kids is: The PlayStation2 ran at 300Mhz and a cache miss would cost you 50 cycles. The PlayStation3 ran at 3200Mhz and a cache miss would cost you 500 cycles. So, if you are cache missing a lot, your PS3 game will run as if it were on a PS2.

In other words, not paying attention to cache make your computer run like it's 10 years older than it is. You paid for a modern machine, but you are getting the results of a Craigslist junker. This is true outside of games. It's the reason 4x2Ghz cellphones struggle to run seemingly simple apps. It's a big part of the reason people struggle to orchestrate armies of servers (distributed computing is easier when it's 90% less distributed).

Is it really harder to work with the cache system instead of ignoring it? Yeah, it requires a tiny bit of study an a little bit of planning. In contrast, the theme I see a lot online is to completely dismiss physical reality in favor or theory. And, the theme I see almost universally in the students (and many senior engineers) I interview is complete ignorance of the very existence of cache and it's effects on the code they write. It's very concerning...
three things:

1. You do not enjoy your work, and thus have no motivation.

2. Maybe you should not do the work and suffer the consequences.

3. You have built a mental dependency that you must take amphetamines to "focus", and this hinders your real ability to focus.

All of those things ^^^ I have experienced at one point or another in my life. You can focus, you have to make yourself. There is no other way. You do not need medication... But maybe you do, I highly doubt it though.
Until Windows 8, which they introduced C++ support on the kernel and deemed C89 as good enough, with the way forward being C++.

Yes, the latest VC++ do support C99 library, because it is required by the C++ standard and the new MSVCRT.dll is actually written in C++ with extern "C" entry points.
I'm surprised they made no mention of http://www.freerangekids.com/ or (owner/blogger) Lenore Skenazy, both of which typically come up in such discussions.

You should absolutely hold them to this standard, but only now that they have released 1.0.
First of all, you are mixing dimensions. If I perceive a kidnapping as an actual occurrence, I will call the police and/or intervene. The situation may be real, or it could e.g. be a stag party.

Risk is different - it's about what isn't even perceived to have happened in a given situation. If I walk in the street, there is a risk a piano may have fallen out of an airplane and be falling towards me.

If I perceive that as a risk, I may take countermeasures, in this example entering an underground garage would stop the (for me as a part of the example) hypothetical piano.

If I often take exaggerated countermeasures as a parent, I may cause harm to the child. The safest child would be the one locked in a bomb shelter on a healthy diet. It would protect against falling pianos, falling bombs, freezing to death, drowning, transportation accidents, school bullies, sexually abusive authority figures, house fires, sun burns - everything except an attack on the bomb shelter ventilation system.

The prohibitive costs excluded, no reasonable parent would do such a thing. (If air raid sirens go off, of course it still becomes reasonable to take the child to such a shelter - until the 'all clear').

If the child is never given a chance to be unsupervised, when will it learn to tell situations and behaviours that carry risk from those that don't? When will they develop their independent sense of judgement?

Anyways, to answer your -hopefully rhetorical - question: Transportation by car is risky on a population level. Playing in the forest or park is not even close. It may also be argued that allowing children a steadily developing autonomy from an early age leads to a lower risk over the course of a lifetime - since the child then steadily increases its ability to handle a risky world.

Therefore, I claim that unreasonable protection is the true neglect of the child.

[EDIT: Spelling]
Did you read the article about the two-year old? The context is that they left him for over an hour and a neighbor found him wandering around outside.

I don't know how much context was put into the actual study, and I agree that we make a lot of moral judgements without all the facts. But it seemed like the jist of the research was that our moral judgements of the parents should have no basis in our assessment of the perceived risks to a child. I refute that to an extent.

I agree there may be a collective action problem here. Being the first individual to follow this practice may be individually harmful, even though having a culture where everyone does it would be collectively beneficial.

I suppose one way to jump start things would be for some forward thinking company that wants to have a solid tech culture should proactively hire elitists.
One obvious exception is the very VC whose blog post you're commenting on. Fred seems to have the same qualities of "The Product VC," but has developed them despite not having exited a company before becoming a VC.
Yup I've been known to do this as well :) I'd have a Node.js + Mongo endpoint ready on the other side.
The marital issues most frequently revolve around the affected partner (if there is only one) acting in disorganized, ineffective, irresponsible ways in the view of the unaffected spouse or partner.

A frequent pattern is that the "normal" individual becomes demanding that the affected partner performs better, which arouses the affected person's opposition and irritation.

Ultimately they become constantly angry at one another. Episodic or constant "warfare" is corrosive to the relationship which ultimately can't sustain the stress, resulting in failure of the relationship.

> If you throttle your scraper in proportion to the size of their site, you aren't really harming them.

And do you understand their site infrastructure to know whether you're doing harm? It's perfectly possible that your script somehow bypasses safeguards they had in place to deal with heavy usage, and now their database is locking unnecessarily.
I've been taking ADD meds my whole life and I've never had anything like withdrawal symptoms. If I don't take the pills, I don't get the effect of the pills: that's all that happens. In fact I regularly skip them on weekends/vacations/etc. to help keep my tolerance low; I've never had any problem doing that.

Someone who's getting amphetamine psychosis off of ADD meds is seriously abusing them. That absolutely does not happen with proper clinical doses.

Thanks for your feedback, I do appreciate it.
There is NO best programmer. Every program, the metric by which a programmer could be measured, is built to serve a specific purpose, meaning you can't really compare programs in different domains. If they serve different use-cases you might not even be able to compare programmers in the same domain. The best system programmer is no better or worse than the best graphics programmer. It's similar to comparing a goalie to a centre. Beyond that programming is as often as not a team sport, you can get better results from pair programming or mob programming from one guru.

Ultimately you want to identify one of a few different types of "great" programmer:

If you want to identify an EFFICIENT programmer, see csbubbles.

If you want to identify a PERFORMANT programmer, benchmark.

If you want to identify an IDEAL programmer, think of which best suites your buissiness needs.
I don't think a deity or a politician or a wealthy philanthropist will save us. We're beyond saving. I think I can teach my kids how to help save themselves and their like-minded peers, those very peers that would leave this planet behind if they could.

As for what stops someone buying a seat on that one-way ride to a brave new world? Two things:

1) Your hypothetical buyer isn't actually that brave.

2) The same reason people can't rush the cockpit of a fully loaded airliner any longer. The rest of the passengers know it's in their best interests, as a group, to prevent that from happening.
> tl;dr: Scraping isn't bad / blackhat as long as you aren't affecting their service or business.

Analyzing data that you're not allowed to access gives you/your company a competitive advantage, which is affecting their service/business even if it's not posted/distributed publically.

I'm honestly surprised that there is still 30M users playing. The original tracking system they had in the game was fine, it worked well and I mostly enjoyed playing the game with it. Can anybody shed some light as to why they removed it?
Ask HN: Has anyone else skipped El Capitan entirely?
Have used Macs for 25 years, and I just realized that El Capitan will be the first major OS version I've ever skipped. I recall seeing that the initial upgrade numbers were low, but I didn't suspect at the time that I might end up skipping the version altogether. Anybody else in the same boat? Would also be interested to know what I'm missing out on, if there's anything cool.
Yes, I have. I am on the drupal.org engineering team. I suggest you look into composer for managing modules. Also there is momentum on building an automatic update system for drupal, (https://www.drupal.org/node/2367319) so, while things can be improved, there really isn't much business opportunity there.
Can anyone explain like I'm 5 what an RPC framework is?
My reflections as a potential beta-user:

- the price is very high - the $89 plan will be sufficient for a small website only!

- why only javascript analytics when I also have server requests?

- the dashboard looks nice

- the website could contain more information - seems too plain for a paid product - a documentation link, company data

Overall, even if the price was lower I don't think I would use the product. It looks like it gives some functionality of more focused tools (like Sentry for error notification) but doesn't look sufficiently advanced.

To do what your product does I use Sentry (error notification) plus parsing of Nginx logs + metrics in a database for timing data.

I hope my remarks are helpful!
So what? Lots of startups that deserve to fail and don't have this kind of arrangement also manage to get more financing, or get acquired or acquihired. That kind of thing is not unique to spin-ins.

I also never claimed the world was a perfect meritocracy. I was saying that if it was, this kind of thing would not undermine it. It seems that we agree on that point. I brought it up in anticipation of counter-arguments that spin-ins subvert meritocracy.
I read that as the parent is going "to go play pokemon" which means it's a reoccuring thing to leave the kid alone.
Count me as reeeeally leery of ascribing harm to an amorphous "cultural impact". Not that I think it's sensible or right that a child might not be allowed to walk around the block, but that in general, as with any other thing other people's parents seem to worry about, the kids are probably going to be fine.

Contrasted with our outrageously inverted reaction to the real and fictional (respectively) threats of climate change and terrorism, it's hard for me to muster up too much outrage. Fix this without fixing them, it's hard for me to clap too hard.

who tracked their every achievement and bandied it about looking for their prize

Who said anything at all about "bandying about" performance? The point of the parent comment is that this information should be reserved for the performance review with your employer, not for office chit-chat or politics. You can't claim your proper value as an engineer unless you know how well you've performed.
I agree that there are people who will benefit from the use of prescription medications to treat different life issues. I too suffer from hours of staring at work, unable to start or finish. I don't think I have a learning disability or a disease that needs treatment. But I think there are many alternatives to help people who cannot start and finish work tasks.

I can usually find a quiet and productive work environment free from distractions. I can usually adjust my caffeine intake levels. I can usually adjust the amount of personally stress in my life. I can usually adjust the amount of sleep. I can usually break up my work into small enough chunks to get started. I can block certain computer activities which are distracting.

Yes everybody is different. No, we should not throw out the baby with the bathwater. Yes, we should be exploring alternative treatments besides powerful amphetamines which can cause addiction and health issues. I don't believe having a problem justifies all the cost that go along with treatment. Sometimes the solution is worse than the problem.

I don't want to have to do drugs at work to keep my career from those who want to take a pill and work for 12 hours a day.
I know that traditionally Instapaper basically required you to load the page at least once first so you'd get all the ads then. But since then there's APIs that bookmark directly to it. My guess is that it isn't used enough for Web sites to bother.

I view it as a specialized browser view, although the cloud bookmarking doesn't fit with that. I use Safari's reading view on pages all the time as they're too visually busy for the screen on my iPhone 5.

> wait, can I get some more info about this? I assumed to cannot go back to old releases. Or are you talking about jailbreaking?

You have to jailbreak current OS, then you can downgrade to iOS 6. It'll be jailbroken, but it's just enabled ssh, you can use it without installing Cydia and everything should work as normal. It could be done only with iPhone 4S or iPad 2 and only if current iOS is jailbroken (at least that was the case year ago, I was able to downgrade from iOS 8 to iOS 6 on iPhone 4S). Keyword to Google: OdysseusOTA. Officially there's indeed no way to downgrade, only using vulnerabilities.

As a parent it's very hard. Our governess mentioned our one daughter was having difficulty focusing. So I did a trial with just 5mg/day Ritalin. Week on, week off. The difference is huge.

It's a really hard call. I'm worried about the effects long term, but she does so much better with it. If she was in a school instead of with a private tutor, I'm guessing she'd be way worse off.

FWIW I used to think giving meds to an 8yr old was horrible. It's not so clear anymore.

TrueConf Named in Aragon Research’s ‘Hot Vendors’ List
Aragon Research, a U.S. business research agency, has named TrueConf a 2016 Hot Vendor in video conferencing. TrueConf has distinguished itself as an International provider of UltraHD video conferences with calling service, SIP/H.323 integration, and WebRTC support.

Aragon Research, an independent technology-focused research and advisory firm, annually selects the best vendors in various IT-market segments. All the nominees are personally tested by the company’s analysts. The agency focuses on powerful regional players who think globally and provide innovative solutions, technologies, and business strategies which are interesting and useful for users all over the world.

This year Aragon Research has announced TrueConf as a 2016 Hot Vendor in video conferencing solutions. According to the analysts, the rapid growth in the popularity of video conferencing in the workplace and on mobile devices has provoked keen interest in UC solutions research. Today, videoconferencing is being implemented to improve communications and knowledge sharing as well as to boost sales and client support.

As reported by Aragon Research, TrueConf won the Hot Vendor award because the service is affordable and easy to deploy. SIP, H.323, LDAP, RTSP, and WebRTC support allows customers to easily use video applications to solve problems and facilitate business processes.
Not many people can take criticism is stride like that. You are awesome.
“Sooner or later, everything old is new again.” --S.King
No, not at all what I'm saying.

My point is that the parent who is accidentally negligent most likely is providing their child with a safer environment than the parents who intentionally leave their child alone.

BTW have you even had a 2-year old? I doubt very much there was ever a point in history where 2-year olds were left with zero supervision. Sure it might be an older sibling or some other community member watching them, but I can't imagine how someone feels leaving a 2-year old alone at home is a reasonable thing.
Are perceived risks lower in smaller countries?

The article mentions Norway, which has a population of 5M. Even if the rate of child abduction is the same as the USA, there will be far fewer scary stories.

1) How many foreign cases does the Norwegian media report?

2) Are Norwegians worried about them? I'd think "oh, America" and move on, but I'd guess that if I lived in Idaho and the case was in Michigan I wouldn't be so dismissive.
Very interesting. This is basically a node.js way to access the core-os etcd distributed locking implementation.

The worst part of parenting is dealing with other parents. Yuppie millennial parents are the worst. I thought I grew up with overprotective Asian parents but they let me wander all around the town at 7-8, stuff that's apparently get them arrested in the Dame suburbs today.
Basically, the article is a strawman fallacy. It paints national health care supporters as people who think, as you said, that health care as a human right would mean that everybody gets treated no matter how expensive. Nobody thinks that. The goal is to reduce the amount of people who are sick and dying as much as possible. We have data on that in the form of the performance of various systems and their impact on health.

The US is still the world's economic superpower, but it's health care system is rated below Dominica and Costa Rica.
The best thing to do here is to accept the fact that some parents will take more risk and some kids will die every year because of that. We cant do a zilch about it besides charging the parents after the incident has happened.

You want to call a method in another process, potentially on another machine. In order to do that you both need to agree on what the networking protocol looks like. gRPC uses HTTP/2 for the control and data channel and uses Protocol Buffers to describe the method call, its parameters and ultimately its return values. Since this is standardized across languages it doesn't matter if the caller is Python and the callee is Java, you can still make the method call.
"Rebuild trust"? This is the first stable release. Every single release before than was called a "Development Release" (and Protobuf 3.0 only came out of beta less than a month ago), so of course they've been breaking things before now.
Yes, it's important to understand that in the United States, web scraping is usually an illegal activity under the CFAA. If you draw enough attention, your scrape target will notice and threaten you, and probably follow through with the suit. Since the CFAA prescribes both civil and criminal penalties, you may even find yourself in jail for accessing data without the company's approval. Aaron Swartz was being prosecuted under these provisions for scraping public domain data.

The CFAA is a really bad law and creates the network effect lock-in that we all considered a natural part of the web. It doesn't have to be that way -- users should be free to use any browsing appliance they want, including so-called "scrapers".

Big companies like Google not only got their start by flagrantly violating the CFAA, copyright, and privacy laws, but they continue to do so. The moral of the story is hurry up and get big before you get sued or arrested.

There's a long history of ridiculous web scraping rulings based on technical misunderstandings by neophyte judges, including Ticketmaster v. RMG, where infringement was found because the company scraped data out of a page with the Ticketmaster logo on it.

Facebook sued a company called Power Ventures which read out only the user's own data. The founder was found personally liable for $3 million in damages. Facebook did this because they don't want it to be easy for their users to move between social media services. If it's easy, Facebook has to compete on merit instead of just keeping switching costs high. Facebook doesn't like that, so they sue people who make it possible -- and the law says they should win.

We badly need a revised law, but the powers-that-be will strongly oppose it because it would threaten their monopoly over web properties. They continue to flaunt their strategic ignorance of these laws and then take shelter behind them to stop risk from small innovators (i.e., having to compete fair and square).

In the real world, we have a lot of laws that mostly prevent this kind of bad behavior. In cyberspace, the structure is such that most of those laws are not applicable. We need to update and port the pro-small-business logic we have for meatspace companies so that it counts online too. The state of affairs online is really bad.

I want to get a law called the "Consumer Data Freedom Act" passed, which would allow users to access any web property with any non-disruptive browsing device, including custom scrapers that don't impose much more load than a typical user browsing session would.
