I've been working part time for just over 4 years now. It is the single best thing I have done for my mental health in the last 10 years. I have a mid-week weekend (Wed and most of Thu off) and it is awesome. I have no plan to go back to full-time. I've also convinced my wife to do the same next year.

Of course there is less money coming in. I've decided to reduce my rate of consumption to compensate for this. Eating out was a huge money sink in the past. $100+ restaurant visits are out of the question now, which is fine because I'm living a semi-retired life, and cooking is less a hassle and more a slow pleasure :)

I got tired of trading the best hours of the day and the best years of my life away for what amounted to trinkets. I've decided to optimize time over money. It helps that my material needs are modest.
Google has 1 million in revenue per employee. They could pay everyone 500,000$ / year and still be extremely profitable.

Edit: 1,259,520$ (March 31, 2015) http://csimarket.com/stocks/singleEfficiencyet.php?code=GOOG

In 2014 Apple had a pretax income of 53.48B and 92,000 employees. It could give them all a 200,000$ / year pay bump and still make 35Billion in profits.

PS: Not that any company thinks this way, but it's not hard to argue that top programmers are underpayed.
Oh, that was fun. Thanks for the link.
I'd like to point out the Slightly Mad quotes about working with AMD. I have never heard of a developer having a good experience with AMD. Even Carmak, the man with probably the most klote for a game programmer, has had a hard time getting help from them. Their support for developers has been why I've been choosing them for my PCs ever since I upgraded from my 9800 Pro.
I downgraded too, also from a Sony Xperia to a $70 Blu Life Advance 4.0. It's got a crappy camera and screen, but it handles tethering 4g, music, can run apps and browse the internet. And dual sim + unlocked. I really can't imagine spending $500 - $700 on a phone again, the cheap end is improving all the time.

Even if someone uses your code in proprietary software, someone else may still use it in something open, or contribute their own changes back to your project. And it is advantageous for anyone improving the code to contribute it to the project, because that makes the project better, and makes it more likely that others will use it and improve it, and you will ultimately benefit from their contributions too.
Sometimes I feel we miss the wood for the trees. Spy agencies implant SPYware, not that surprising.

Surely the real story, the original Snowden story, was about PRISM the way large corporations do the bidding for spy agencies letting them tap information at the source. This was quickly drowned in a sea of other stories, and is hardly ever mentioned any more.
Nothing quite like seeing the sausage get made. But, the open discussion, while perhaps unnerving, is certainly preferred (IMHO) to a closed source development process happening behind closed doors. A bit of chaos is the price to pay for the open process.

Command-and-control does have some advantages. And maybe as Postgres grows, the advantages related to a more orderly process become more visible. (For the record, I think Postgres is a fantastic RDBMS + JSON store)
Net metering doesn't make sense. About half of the cost of residential electricity goes to running the grid.

That being said, electric companies aren't stupid. If / when solar power and batteries become ridiculously cheap, they will just switch over to solar and batteries.

Residential off-the-grid solar power will make sense in two markets:
- Highly rural areas where it's very expensive to maintain power lines.
- "Be prepared" cultures like Utah where people take pride in preparing themselves for Armageddon.

> Why would you want to do this when net-metering exists? Let the grid store your excess power, and buy it back from them. Run the math, you'll see which one is cheaper.

That's great in places where the grid is required to take your excess power at rates similar to what you will end up paying at the times you may want to buy it back.

How many places does that apply to? (EDIT: I'm genuinely curious; it's not a rhetorical question, just to be clear)
I do that too, but it's no kind of assurance as any half-competent hacker would test his trojaned versions against various anti-virus software and when it passes all upload it to VirusTotal and similar sites to convince people who rely on such sites. Best thing you can do is to download it from multiple internet connections (via VPN/TOR) and hope that any mitm is closer to your side and not server's side.
This is a good example of asking the wrong question.

How fast does an electron move? 2200 km/s.

How fast does an electrical signal propagate from one end of a circuit to the other? This is a much more relevant, but also more difficult, question. The unit used to measure this performance is called Velocity Factor [1]. Unfortunately, I don't know what the VF would be within a modern microprocessor, but in a wire, it varies from 50% to 99% of the speed of light in a vacuum.

As is typical for mass media news, this story has been summarized in a way that glosses over a lot of the detail.

Photonic computers have a very, very long way to go. Even this tiny beam beam splitter is thousands of times larger than current transistors. Intel uses a 14 nanometer process for Broadwell. The University of Utah beam splitter is 2400 nanometers square. Let's not ignore the fact that a beam splitter and a transistor aren't even close cousins. A beam splitter can't perform any logic.

All of this technology is still very much in the realm of basic science. A lot of the assumptions about the speed improvements are based on napkin math involving theoretical numbers. If anyone ought to know that the difference between theory and reality is often muddied by the trip through the physical world, it would be Photonics researchers. Fiber optic (probably the most widespread application of Photonics research) performance is significantly impacted by real-world factors. Far more so than electromagnetic mediums.

But it is a look at the process that eventually impacts users. It explains why upset has taken so long. A bit of chaos and a bit of politics.
I switched from a $550 two-year-old Android phone that has become unusably slow to a new $200 phone that is snappy and quick, network permitting.

I really think the age of the phone has more to do with the speed than the price (and I suspect this has more to do with software than hardware going bad.)

LHC smashes energy record with test collisions
I think a lot of it really depends on how often and for how long you use the phone. I spent $500+ for my iPhone 5s and I've used it for almost 2 years now with a cheap Virgin Mobile plan. I use it daily (maybe too much even) and once I upgrade from it, I'll continue to use it periodically as a testing platform for my web development. I'll probably get another year or two of use out of it for that purpose before testing for the 5s isn't worth the trouble.

And honestly I can't stand the cheap Android phones. Android is a solid OS, but the cheap devices it often appears on are just awful. It causes a lot of headaches...at least $500 worth to me at least :)
Handing over specific user data when requested is a lot different that handing over your encryption keys though.

Using the 7 KW-h power wall (the daily cycle one), about 4.3 million. Tesla vehicles use 80-90 cells per kilowatt hour of capacity, so about 365 million lithium ion batteries would get you to 30 gigawatts (also, the claims about the Tesla Gigafactory have it producing a bit more than that per year).
It sounds like you're unable/unwilling to consider relocating as a way to minimize cost. That's fine—everyone is entitled to live where they feel is best for them—but there are plenty of locations where you could get much more space, in a good location, for less than $1400/month.
Article is obviously for PostgreSQL developers BUT my gripe as a user (coming from MySQL).....the hardest part about transitioning from MySQL to PostgreSQL isn't PostgreSQL itself but transitioning from phpMyAdmin to phpPgAdmin. phpPgAdmin seems like it's trying to make my life difficult.
> A $3000 gas generator will get you 10KW of power.

They kill people on a regular basis (due to misuse, but misuse happens). I don't need 10KW, either, I just need enough to power the furnace so I don't freeze to death.

> Why would you want to do this when net-metering exists? Let the grid store your excess power, and buy it back from them. Run the math, you'll see which one is cheaper.

The math will change if everyone does it, I'd imagine.
Long time ago I visited the home of a young entrepreneur that had spent all his money installing optical fiber all around his home.

I remember what I thought: How stupid someone could be. It does not make financial sense at all when it was so expensive.

Turn out I was the stupid one. This man created a company doing exactly what he had done in his house but for others and made a ton of money.

In some way he paid a cost for living in the future, and he understood the practical shortcomings and advantages of the new technology much better than anyone else, which made him succeed when others failed.
> A buddy of mine working at ORNL claims there's interesting stuff on the storage front that's competitive with pumped storage, but can't say just what yet. I'm highly curious myself.

http://prod.sandia.gov/techlib/access-control.cgi/2011/11273...

"Table 4" is probably what you want to look at. As you can see, only Compressed Air is competitive with Pumped Hydro as far as energy storage (w-hrs).

It looks like Compressed Air is going to be the golden standard a few years from now. There was a relatively cheap compressed-air plant created out of abandoned mine tunnels that was hundreds-of-Megawatts in scale. I don't quite remember the name of it however.

Also, Compressed Air doesn't require you to empty a lake (and refill it) every day. So California's low-water situation may prefer compressed air storage systems.

Redox Flow batteries look to be the most promising technology at utility-scale chemical. Chemical solutions are needed for their versatility... but "long-term" energy storage (such as day-night load balancing) will likely be handled by Compressed Air and/or Pumped Hydro.

Currently, over 95% of the US's energy storage capacity is in pumped hydro.

I don't assume he's rich. I assume he is a decent financial investor living in Delhi where a 3-bd apartment in the city is ~$700/mo. His reported annual compensation on Bloomberg is $105,000. While he may not be Warren Buffett rich, it's still substantial in India. I do assume that if he were living in the US at the same rate, he'd probably be working more than 3 days a week.

I understand he's advocating for less work. Why do you assume he's advocating for consuming less? He could be buying new Jordans for every run he goes on. His couch could be rhino leather for all we know. Personally, I doubt he's advocating for less consumption because he sits on boards of businesses who produce basic goods, like food, paper goods, and He also sits on a board for an event production and marketing company. It's hard for me to believe he's down with less consumption.

As others have explained Tachyon does the "put dataset in memory" part.

Spark started off as the "in memory map reduce" but has now become a platform for Scala, Java, Python, HiveQL, SQL and R code to run. It is the most active Apache project and is getting more and more powerful by the day.

Given how easy it is to get running it wouldn't surprise me to see it in the years to come being using as the primary front end for all data needs.
That's not true at all. An employer can demand that a salaried worker be in the office during particular hours. It just means that if those hours are > 40 per week, the worker doesn't get overtime.
The story is that agencies that are tasked with foreign spying are spying dragnet-fashion on their own citizens and citizens of allies.
When it comes to privacy, is Chromium safe to use?
I go back and forth on whether to use Chromium or Firefox Developer Edition. I generally, like to keep up with the latest updates. In my experience, Chromium is fast and stable. I would like to use it, but I give a great deal of importance to my privacy. As a rule, I do not to connect to Google unless its important. I use uMatrix and uBlock addons, and startpage as my search engine. With uMatrix filtering, I only allow ajax.googleapis on websites only when its required.

So, my question is this. Can I use Chromium? I know that it connects to google servers on every startup, and it updates extensions automatically. So, whenever I open the browser, Google knows my IP address and the list of extensions present in my system along with other browser details. I can easily avoid this by using Firefox, or am I being paranoid?
> Drawing from the same law that regulates legacy phone service, net neutrality prohibits the sharing of your subscriber records with third parties unless you give explicit permission to your carrier.

For those wondering about the "explicit permission" mentioned here, there are two methods ISP's we be able to use to use your information, if they indeed follow their telecommunications privacy model[0].

> “Opt-Out” – Your company sends you a notice saying it will consider you to have given your approval to use your customer information for marketing unless you tell it not to do so (usually within 30 days.)

> “Opt-In” – Your company sends you a notice asking that you expressly give it permission to use your customer information for marketing.

Regardless though, this article left me wanting. If you're curious about the details, Ars[1] has a great introduction to it.

A Cranky Critique of Chrome's “Enhanced Bookmarks”
Right, but the difference is that their monopoly was in a created market, vs Slim's which is the definition of a bad monopoly (sole supplier of a utility). Their margin was the reward for the creation of something new, not taking a cut on a natural resource. But I agree that it's not black and white - companies lie all over the spectrum (you could argue that Slim is getting paid for the effort of putting out a telecom network in Mexico).

A clearer example is Google: it has an effective monopoly on search, but it's not because it has lobbied Washington to stop people from using other search results, it's because it was the best search engine, spread like wildfire, and kept the market ever since. People use Google not because there's no other (legal) search provider available, but because it's still the best way to find things on the internet.

Because of this instinctive understanding of the value created, it's much rarer to see Brin and Page criticized for their wealth.
I feel compelled to point out that the average SSD has an order of magnitude (or maybe 2 orders) more IOPS than a 6-disk 15k RAID6 or RAID10 array.

And that's a single, standalone, non-RAIDed SSD. When you get a 6-SSD RAID10, magic starts to happen. And if you RAID enough SSDs (10-20?), you can theoretically start to get more bandwidth than you do with RAM.
I'm 100% confident that it's 85% accurate. The problem is that our sampling rate was too low. I can only make so many statistical interpolations before it starts to look like guesswork. Yes, management was aware of the issue. Luckily, the people whose bonuses were affected could not possibly have enough information to dispute my results. :-P
It's a reasonable cloud vs. on-premise argument. Obviously the scale of the data transfer to a cloud has more to do with the dataset size than the number of instances.
Nobody likes negativity, especially on HN. But rather then explicitly condemn the negativity and be excessively positive for no reason, why not analyze why people feel negative?

Believe it or not, negativity can be justified. And although wealth is a controversial topic I believe that an innate feeling of unfairness that most people feel towards the super rich exists because it actually is unfair. This feeling of discontent has toppled empires and changed entire economic systems. It is worth it to explore this negativity rather than suppress it.

>I'd rather figure out what this guy did right and take steps to implement some of those things into my life.

It is not physically possible for everyone to live this way. No single man has the intelligence or strength to contribute enough GDP to the economy to justify such wealth. If you want to live like him you must exploit the labor of others. In short to be rich sometimes you must do things that will promote feelings of negativity in other people.
I wasn't suggesting those are all the solutions to your woes. There are many creative ways to live and the solutions that are right for you aren't going to be the solutions that are right for everyone. Perhaps you're living the cheapest way you can in the environment you have to be in for the moment, perhaps the only creative thing you can do to live the life you want is to re-prioritize. Perhaps that is not feasible for the moment either. Only you know the answer to that.

Costco does have a membership fee which (I think you're right) is $75 a year, but you get an annual dividend out of that membership depending on how much you spend there. Over the course of your annual membership, it's easy to save way more than the $75 you spend between the dividend and because the cost per unit of goods are much cheaper for many things.

Solar panels can be expensive, it's a good idea to keep your eye on sales, flyers and auction sites to get great deals and only buy when you find a good deal. I have no idea how much installation would be where you live. Me and my father-in-law are both pretty handy and Google pretty much tells us everything we need to do to install them. All you need is an inspector. With Google you can pretty much do anything you can imagine with a bit of ingenuity.

Having an apartment is limiting, for sure. But even growing some produce in the window will save some money.

Making bread and pasta is easy: Flour, salt, eggs, water, yeast will see you through both. Having some basic ingredients in the house will take you a long way to being able to make whatever you want without having to pay retail for it, and it's thoroughly satisfying. Again, Google is your friend.

Congrats being debt free. That is a tough thing for many/most people to be able to say in today's economy.
You should have bought a goddamn lumia. That thing beats android in every way.

You know, I would probably choose to work half time for half my pay, but very few interesting jobs allow for that. I don't know if it is cultural or what, but employers expect people to work 40+ hours per week and don't really make provision for other schedules.
I honestly don't know why anyone would use Cascading or Scalding when Spark exists.

Sadly this is par of the course of the whole computing industry.

Just look at how Apple pretty much gets to set up a store inside university libraries. Or how the likes of Adobe or Microsoft will throw virtually free copies of their products at students.

In short, no. Employers can demand that you work whatever hours are necessary. Source: http://www.nolo.com/legal-encyclopedia/question-work-overtim...
10k? Those sticks of RAM alone will cost you something like 75k USD. Then you'll need the processors, arguably 4 of the top of the line 18-core XEONs at 5000 USD each. Then you'll need to put it all together with software and a (properly cooled) rack, not to mention the terminal(s) to access it, plus the personnel to put this baby together for you. This box could easily cost you 150 grand.
I understood more after using some citizen science project where you classified particles by their trajectories using images like these. Basically, if you didn't figure out that part, the images are cross sections of the vacuum pipe and show the trajectories of the particles that come to exist in the collision of the accelerated particles
The centralized grid is going to stay regardless of how many homeowners buy powerwalls; only so much can be buffered on the consumption side. Because another thing this article doesn't address is the fact residential power use occupies a mere 18% [1] of power consumption. Commercial is only 12%.[1]

Maybe you could store enough energy to run your datacenter overnight. I'm speculating, but powering a chip fab or even a machine shop on batteries seems infeasible.

But, I agree that there is a major imbalance and generation/storage on the consumption side would help correct that. Reduced need for peak generation --> greater net efficiency.

Transocean Fines Ends Up Net Positive from Gulf Oil Spill
I use a Galaxy S (the first version), purchased 4 or 5 years ago, can't remember. Upgraded it to KitKat with a custom build (MacKay) a year ago, was happily using Froyo before that.

I love it's small footprint and plastic back. It's kidproof, verified by my two test engineers here in various incidents. Changed it's battery once, lasts almost two days based on my usage.

For the last three years, I'm trying hard to justify buying a new phone based on my use case and can't come up with a good reason. I shrinked my usage to email mostly. Twitter is so time consuming, I'm happy that my phone can't keep up with it's basic hardware requirements so I gave up using it 2 years ago. Same story with Facebook and other popular apps. Staying long on a not up-to-date hardware trims your excess device usage and makes it hard to have a reason for upgrade.

I was about to buy Xperia Z3 Compact for its smaller size and long battery life but turned down by glass back and lack of physical home button. I guess I'll shop for a second hand Galaxy S if this one dies on me.
