Like with everything, it depends. The way you use time is key to pretty much everything. The right hurdles to go for, for learning, are always the ones where you are outside of your comfort zone and you have to struggle for some number of hours, days, etc. to pick up the concept.

But the other half of that is to have a well-rounded life that will keep you on track. If everything feels like homework, you're stressed or unhealthy, etc., it'll be hard to summon the energy to really struggle with a hard problem. Try slicing up your year into the fractions of time you'd expect to spend working on anything. When you budget it this way instead of making a rigid schedule, you spot opportunities to break away from everything else and spend a week or so just trying to do one thing.
Sometimes it's an arms race. The minute you automate away some analytics step, the smart analysts start building on top of that, raising the bar for the competition.

Also because it's really hard to get published if you're not working with an organization. It has happened to me that I had to take someone as coauthor just because they knew scientific-paper-ese and were associated with $BIGLAB.
> I work as a university, and every term I have to prepare a program that sends out end of term letters (probation and suspension). Which college do you think gets the most of those, per capita?

Sounds like the system is weeding out the "gamers" pretty well in that case.

> Just because money is wasted elsewhere doesn't mean all should be invited to waste even more money.

No but it does mean there's plenty of low priority things to cut to go towards education.

> if you raise the status of the job, you get status-seekers, if you raise the pay, you get money-seekers.

This is categorically false. Taken to the extreme it means we should pay teachers NOTHING. Then we would get only the really good ones!

Funny thing though, those people. It's almost as if they weren't simply optimizing for a single factor like money or status. It's almost as if they consider a wide variety of factors from pleasure, intellectual challenge, concern for legacy and leaving a mark, and yes gasp whether or not they can support themselves and their family and to what degree of comfort.

Ask HN: How is Postgres-XL progress coming along?
Hello HN,

For the past few months I've been in love with Postgres-XL[0]. It seems a wonderful solution for horizontal scaling on relational databases without involving sharding (which can get messy).

However, the website is quite short on news. Although it seems awesome, I barely see anyone talking about it. The mailing list gives me some information, but I'd expect way more "buzz" for such project. Is anyone here using it in production? Or maybe testing?

Thanks

Thanks, that's also fixed.
Blackhat Film Review 2015 – Dwidi Video
Dark matter and black holes have nothing to do with one-another. Even in your linked article, Dr. Hawking is not arguing that black holes don't exist; just that their properties may be quite different from that which they are widely expected to be.

There is very little reason to doubt, and in fact there is enormous observational evidence to support, that there exist (and yes, that we have discovered) bodies in space whose mass is contained entirely within their Schwarzschild radii.
>In the end I ended up cured of most forms of political fundamentalism.

Yes! The only cure to social issues is applied intelligence. We should treat governing, policy, economy, and social norms with experimental elbow grease.

No fundamentalism can work. The only way is to try things, observe, and try again. Government is always a work in progress.

Instead we have these polarized fights between communists and capitalists. What we need is a balanced and experimental, flexible, modifiable socialism.
Thanks so much for the stellar comment. It's truly great, and I really appreciate it.

Are you absolutely sure about those salary bands? In particular, less than $100k minimum for a developer with ~ten years of experience seems extremely low. They could go get that much in a starting position at a trading firm, so why go infosec? If you can do anything, why do that?

Those salaries seem reasonable for ~2006, but not 2015. They say to reinvent yourself every ten years or so, but starting out at those salaries would be prohibitive.
Can't believe the article didn't mention the Big Dig at all.
Writing a program is exactly the same thing as proving a mathematical statement. This is an extremely cool and deep result. Start with the Church-Turing thesis and go from there.
> Despite the claims of marketers everywhere, lag can't be eliminated.

I understand Mercedes "solved" the lag problem with their F1 power unit from last year: they split the turbo into 2 and put an electric engine in between both sides to keep the intake side going while the engine is at low rpms. They got 80 more hp than anybody else dominating the season.

Turbos are an energy efficiency compromise: you only use them (and waste gas) when you really need the extra power.

It took an earthquake to get the demolishment underway...
Wal-E is a backup solution, and has something that Mongo doesn't it is capable of backing up every transaction and restoring the database state at any point in time. Because of its nature it can be used for replication.

Wal-E was written for use in cloud which has its own challenges, but if you want to run in your data center the closest thing is Swift in OpenStack.

As for Mongo, my company is currently using it, and I wouldn't say it's any easier especially when you try to use it in public cloud, when you no longer have guarantees that the instance you set up won't be terminated and recreated in different AZ. There are plenty of challenges.

I'm currently working on convincing other teams to drop using Mongo and instead make queries directly to Postgres which is our authoritative source of data. The idea was to simplify our infrastructure, and I was not expecting much difference in performance but oh boy. In all of my POCs that I did so far PG is beating Mongo that makes you feel sorry for it. Both in performance (you need to understand what you're doing and use right types, indices and queries) and data size (after moving, the data is much smaller so it no longer requires being distributed, and also the instances can be much smaller).
Actually just found out about -of-type's, very powerful.
LED noise is not due to something vibrating.

The definition of noise is, literally, something vibrating.
Thanks for that point. I was extremely lucky to have role models: Both of my parents are retired industrial scientists, and had good careers. But they were also the ones who first warned me that you don't go into science to get rich.

I also got lucky with my choice of advisor and thesis project. While the topic of my thesis was an esoteric matter of academic interest, the _execution_ was an honest to goodness engineering project involving optics, electronics, and programming. So I had something to talk about in an interview.

I actually don't mind having work imposed on me. Among the many reasons why I left academia, one is that I simply didn't have my own research idea. I've even told my boss that he can assign anything to me, so long as he is confident that it's urgent, meaty work.

Now, I'd have a tough time sitting in an office, manipulating pivot tables and "dashboards," and bikeshedding at stand-up meetings.

Another myth or bias among a lot of grad students is that they have to be loyal to their specialty. I was fortunate to be fairly opportunistic about my technical interests.

I should also note that I'm reading all of this with a less than arms length interest: Both of my kids are potentially interested in science careers.
Why I'm Skipping My Annual Physical
Steve Ballmer totally losing it while dancing to Fergie
Seattle area has another, much more similar highway concealment project that's already built - the I90 on the Mercer Island is partially underground, with the "roof" being used for things like parks. Unfortunately, not the whole length of it is buried, so there is still plenty of highway noise throughout the island.

Mercer Island made me think all auto roads should be built like this, and surface should be entirely reserved for pedestrians, bikes and the like.
I think we'll be in the dark on this one for some time unless things change in such a way that would require more information to be released.

I strongly dislike this paternalistic approach, and I'm rather tired of the people being treated like children. We know things are complicated. We know geopolitics are more complex than "USA good, NK bad" or vice versa. They could say a lot more than they are saying without compromising their intelligence gathering capabilities.

If the US government wants support and trust, it needs to earn it from every new generation of citizens. If it doesn't care about support and trust, it has overstepped its bounds as a representative government and should be reeled in.
The Information Security Challenges We’ll Face in 2015
For someone that is new to Rust how do I discover where the libraries are for the things I need to do?

In the past year I have needed libraries for HTTP, XML, JSON, CSV, arg parsing, image manipulation, PDF, RDBMS, a trie (and other data structures), async i/o, threads, files, ZIP, and others.
Neither the person you are replying to or the OP says you need to work 40+ hours a week and spend 10-15 hours a week practicing. Most things which have long term benefits only require 15-30 mins to do them and see results. (exercise, music, foreign language). It really does build up over time.
This is a terrible idea. Totally irresponsible. We have animals in need of loving homes already.

OSX really needs adjtimex or ntp_adjtime for high-precision clock synchronization for PLL loops (unless there's another way). If XNU devs wont do it, I may consider adding a new call to the sysent table via a kext (easier to do because of advances in modern open source rootkits). There's a partial port from a BSD to XNU for a starting point. XNU devs ignored that patch author entirely the first time. It's really a shame when collaboration for useful improvements are turned down.
I've always thought a good compromise between these approaches, and for a while it kinda looked like at least Rubinius would go to something like it in the Ruby world (but efforts to modularize the ruby stdlib seem to have fizzled somewhat), would be to have a minimal stdlib but a broader set of basically LTS versions of exceptional packages, where they are expected to have important issues backported to a stable version alongside a version of the runtime itself.

This would still allow for pulling up to the bleeding edge, or simply not using, of some of those blessed packages if you choose to by specifying them in the cargo manifest, but would still provide guidance on basic useful packages.

I think it'd also be easier to boot stale packages in new releases (ie. the eternal security fail that is the yaml lib in ruby's stdlib).

Is there a way to contact you? If you are willing to be a guinea pig I have something for you to try.

From the three main things people need (competence, relatedness, autonomy) you seem to be missing autonomy.
Yes and it's also because the projects you'll typically work on in a corporate environment are like maintaining and adding features to boring CRUD apps and your skills will atrophy if you don't actively seek interesting, challenging work on your own time.

Bitcoin exchanges aren't very profitable. The numbers for Mt. Gox are available now. [http://www.businessinsider.com/mt-gox-financials-2014-2] The numbers for 2013 are actuals; the future-year numbers were pure fantasy. For the year ending March 31, 2013, Mt. Gox, the biggest Bitcoin exchange in the world at the time, made $286,000. That's all. For comparison, the average profit for a single McDonald's location is about $200,000.

The Bitcoin exchange business has low commissions, and they're heavily discounted for big traders. Sometimes all the way to zero. It's hard for an exchange to raise prices. So exchanges tend to look for other ways to make money. Those ways usually aren't good for customers. Trading on one's own exchange and front-running are tempting. Mt. Gox probably did that; many users observed that, during busy periods, trades did not appear to be first in, first out.

That's why no major financial firm has entered the Bitcoin exchange business. It's not very profitable.

Five million dollars were lost.

Unless you're speaking as a founder in the field, I'm finding this hard to believe. Five million dollars is about an entire Series A round. Or at least half of one. And a Series A round is supposed to last multiple years. Or at least a whole year. It's not chump change.

And I've heard you're going to have no luck raising money at all if investors catch wind that you need it to survive. "Slightly less favorable terms" probably means the deal doesn't happen. See e.g. http://paulgraham.com/pinch.html

But I have no experience at that, so I admit I'm going off of hypotheticals and what other people say.

EDIT: Also, that's five million dollars at current BTC prices. Bitcoin has only recently fallen to $300/coin. It was $600/coin not to long ago.
In other news, engineers refuse to do a code review of a pull request with 1 million lines of code changed.

As has been mentioned elsewhere, the issue may be the "code bomb" nature of the way the paper was published, and if it was released in even smaller chunks, it may have garnered more analysis.
The salary bands are the sort of thing you'd see listed on a page devoid of context. They're minimums and flexible.

If you have 10 years of dev experience and you're a strong enough case to get a yes from an infosec firm, they're going to work with you on salary to get to your level. As 'tptacek has explained quite a bit on here, a good firm is receptive to negotiation and starts at their floor, not yours :)

But your title will still be Associate because you need to learn the ropes. They could also fast track you too so you're a consultant within a year if you're ready.

This is a one size fits all chart. For mid career switchers and new grads alike.

There ARE 100% electric super cars out there, but what's a Ferrari without the roar of their V8 and V12?
Yes, but occasionally they will retire instances, and notify you. If you don't spin it up as another instance, well, sucks to be you when it disappears. Actually pretty simple, but you can't just set it and forget it; you have to be prepared for some degree of elasticity.

Also note that reserved instances don't require you to pay for 24 hours X 30 days. It just gives you the right to pay a lower rate for the capacity you've reserved.
Cool! Great help for beginners like me. Pretty organized
Yup. Hurricane Sandy should have been enough to remind folks of this.

Natural (and unnatural) disasters happen, and you have to be prepared for this contingency. There are many tools out there which can help with this, but a competent sysadmin will help a hundredfold ensure that your business continues when the unthinkable happens.

Heck, only today one of Amazon's new datacenters on the east coast had a 3 alarm fire[1]. Didn't end up having any instances fail, but we did notice some of our services have problems that coincided with the fire, and we were ready to fail over the moment instances started dropping.

> replacing the powerful bulb with an under powered LED.

I've also seen that Sony and Epson are selling laser illuminated projectors as opposed to the more common LED/halogen/etc illuminated projectors. Apparently for high luminosity, laser becomes more efficient and less prone to damage than both LED, halogen, incandescent, argon/xenon etc.

But it disappoints me that these projectors just use the laser for illumination. I'm waiting for when we have laser-on-DLP without filters type projectors.

You probably should think again.

This varies some, but most people are locked in for most of their dollars. They may have savings, and can vary that budget some, but there just aren't the billions of dollars out there often cited.

There is a delta from what is being sold now. But it's not multiples. Perhaps additional fractions.

As for the hard to pirate industries, who says?

They must compete with easier, more flexible options. They might actually get less spending than they would otherwise with a more flexible and accessible scheme.
