Who's this "we"? The general public and politicians have learned absolutely positively nothing. The engineers could talk your ear off if you're willing to listen, about solutions that will never be permitted to be applied.

I mean seriously, looking at the disasters we've had, pragmatically noting the engineers have not been given free reign to fix existing plants or build newer safer plants, at least in the west, there is no way anything short of space alien invasion could shake "us" into action.

For example, you build a plant designed for thirty years of operation, invent a safer way to do things twenty years after the old plant is built, then operate the old plant unchanged for fifty years for financial or environmental protest reasons. Then act all confused around year fifty when something blows up that was a known and fixed problem thirty years ago but can't ever be implemented.

There are numerous source code / programming analogies relating to sunk cost fallacies and political footballs and the like.

Its not just the engineering department. From a pragmatic crisis management standpoint some CYA civilian cultures should not be permitted to operate reactors. Military combat crews universally have more effective crisis management techniques than even the best civilians teams, even cross culturally. To say implementing this management shakeup would be tricky would be an understatement, however "we" do know that some cultures just can't operate a plant without civilian CYA-ing themselves and their neighbors quite literally to death. Civilians in high positions are trained by the system to prioritize protecting themselves personally from future court cases over accomplishing the overall mission of not melting down the plant ... the plant will take care of itself, at least it always has so far, and prioritizing themselves is how civilians rise to positions of power ... put them in charge of a crisis and it melts down and everyone dies ... somewhat more gung ho military personnel will do things like dump raw seawater into a sub reactor to prevent a meltdown, even if it results in a guaranteed economic kill of the reactor, even if they have to improvise. If you grab the tiger by the tail you will get eaten if you text message blamestorm over who's responsible and who wrote what proper procedure instead of holding on tight to the tail. You can't just engineer safety into something and call it done, anymore than you can checkbox security into a web application and call it done.
you can use GPL in commercial products. Just follow the GPL. It's not ant-commerce. Oh, you meant "proprietary" products? The set of commercial and proprietary is not a union, it only overlaps.

Hey I just checked out your app on the App Store and I should tell you it looks really clean! As someone who makes iOS apps I know how valuable feedback on your work can be.

Regarding the lack of push notifications, I believe it works for apps like fitness and news apps. However a new messaging app like yours installed on a user's phone will need to inform said user of occasional updates as that's what we now expect of social networking products. Might not necessarily be push notifications but maybe a daily email summary would work?
I've never understood that reply. I like a lot of modern art, but obviously the person in that conversation is just going to say "because it's pointless and I have better things to do, and galleries won't pay millions for my large blue squares".

If you want to convince someone of the value of modern art, you need to do better than "this piece is important because the artist was the first to think of this incredibly basic idea".
nuclear could replace the entire base load. If you factor in CO2 emission externality costs, it might even be cheaper to run nuclear above baseload. Build solar to help with peak usage and rely on gas for peaking as well.

The surplus could be used to pump water up damns or charge batteries. Or even to just pull co2 out of the air to compensate for car emissions.

It could provide very cheap night power for electric car owners. Worst case we could just waste the energy.

Once you accept that co2 emissions are an existential threat to the world, small inefficiencies are a small cost.
I remember, back during their heyday, listening to pundits discuss how Groupon was going to run Google out of business if Google couldn't find a better way to offer daily deals. I regularly saw people mentioning Groupon in the same breath as Amazon and Apple when speaking of tech giants.
Ask HN: How to Switch “Genres” of Computer Programming?
The title of this thread says it all but I will provide a little more context.

About 3 years ago I graduated college with a B.S. in Computer Science. For my first 2 years out of college I worked on an Android app at a Big Company that you are probably familiar with. During that time I made a lot of big features and got to work on support related infrastructure like automated testing. We also had a lot of people using our app which was a great feeling. I learned a lot about app development and really enjoyed it.

About a year ago I started getting bored at my job and quit to pursue freelance app development. Since then I have worked on 3 pretty big apps. It has been fun but I discovered something disturbing. For each app I work on I find about 50% of my time spent developing is interesting and creative. The other 50% is well... I feel like I am constantly reinventing the wheel. Once again I am getting pretty bored.

I considered switching from Android dev to something else like web development or maybe even iOS. But I have a strong suspicion that I would experience the same issue. I have a feeling that I am just not that into developing consumer facing apps.

Given my position as a freelancer I am able to spend a good amount of time on self education while still being able to maintain my relatively inexpensive lifestyle. I find computer security and AI to be incredibly interesting but I have no relevant experience in either of those things. Even if I read a bunch of books on it, how would I get hired?

I guess what I am asking is, has anyone here jumped from one genre of programming to a completely different one? What was your experience like? How did you get paid once you made that switch? Were you able to maintain your current level of income or did you need to take a pay hit? I really can't go back to school so I would like to hear about the DIY approach to doing this specifically.

Would appreciate any stories etc.

Thanks!

I beg to disagree. That makes the assumption that alien civilizations are in the same technologic era as the earth.

I don't see any reasons to believe they'll be using the RF spectrum. Simply because RF is about all we can manage to pick up is not sufficient reason.
Was only yesterday trying to get Fedora 22 running in a VM (using Proxmox). Live "cd" runs fine, but reboot into installed system hangs.

Maybe I'll give Fedora 23 beta a shot.
It always seemed strange to me that the coupons were essentially "get a $30 gift card for $15, to use whenever", when it seems like a lot of the deals could actually be good for both parties if structured more rigidly.

For example, selling a $5 cinema pass for a specific day, time, and show. So they book the whole screening room, sell exactly as many passes as there are seats, pack the house, and hand you your popcorn on the way in. Similarly with restaurants, where the whole venue could be booked out, and there's only two meals available (kind of like Summerlicious).

You're definitely not getting the regular-experience-but-cheaper doing that, so there's maybe a better chance of converting to try it out after the coupon, but even if you're only ever going to do it on the coupon, you can do it over and over again if it's good for both parties. If Groupon's marketing muscle can pack the house with cheapskates a few Tuesday nights per month, that's probably an all-around win.
I stopped using groupon because of the near-universal resentment I felt from the employees of the stores selling the groupons. Clearly, these businesses weren't getting the value they thought they would get, but I wonder how much of that was the way they treated the new customers that the groupon generated.
You're getting shot down here. Perhaps if you found an argument NOT based on the music model...

The pigz -11 option uses zopfli which is the algorithm referenced in the original article.
At my last job I left last week, we were looking for an alternative to the old GitHub/Jenkins setup, tried Stash/Bamboo for a while, but eventually settled on GitLab and GitLab CI (7.1x, with the Ruby-based CI runners) because the integrations with other services were already so mature. It took minimal customization to our Hubot to recreate our devops scripts and was really more of a drop-in replacement for what our Ruby shop needed. Although we eventually bought an Enterprise Edition license, we were still running the Community Edition (mostly because I left and just ran out of time to migrate), but were hardly lacking anything in the choice to stay on community until other more pressing migrations are dealt with (thanks first-gen Rackspace cloud).

If you're looking to centralize your devops infrastructure, I'd highly recommend GitLab over anything else unless you have a specific use case that GitLab isn't trying to solve (CF's BOSH, or a tighter integration with Atlasssian in a JVM shop for example).
I was never arguing that we would meet baseline demand with "renewables" stored in some sort of mechanism.

But if you're really convinced this problem is unsolvable, lets just do this: we'll generate enough power (with fission, or whatever you want) to meet peak demand all the time. As long as we're near the coast there is a convenient way to get rid of all that surplus energy: desalination plants. I can think of a few areas that would jump at this idea, like California. Even if you wind up with too much freshwater, just start dumping it back into the ocean. The salt is generally worthless and is dumped back into the ocean. This will actually help offset the fact that the oceans are desalinating due to the ice caps melting.

Electricity prices will go up as a result of this, but you'll be subsidizing the fact that the grid is now greener as a result.
It's a sensible name, considering the previous name, but there's still a part of me that's sad that they missed the opportunity to name it Nucleus.
A new app will pay you $11 a month to let it track every video you watch
The deals I saw, felt rather crazy to me.

A friend of mine paid 100€ for 100 pizzas, one every day. Also 100€ for 100 pasta dishes.

The idea seemed to be, that the service could plan ahead, because he knew months before how much ingredients to buy.

The delivery service who offered this deals closed down after a month, so in the end every meal did cost my friend about ~3€, which isn't bad.

I pay them $20 a month. I needed HTTPS back in the days before that was part of their free plan and kept on with the paid plan.

I'm not sure what features the free plan lacks, but $20 a month isn't going to break the bank. I found their application firewall very useful for stopping spam registrations.
I'm no expert here but current job duration may be counter-intuitive. We usually think that the longer the better but it may also correlate with inability to find another job, so in fact during a recession, these kinds of people may actually be more at risk than people used to job-hop.

It probably needs to be controlled for social class and job type but I think this could explain the phenomenon.

Playing devil's advocate here...

You do have to consider the advertising in the calculation. If they spend $2K/year on advertising now, and a GroupOn sale might be viewed by 10K/people and purchased by 100-150, then still might come out ahead even with $0 or -$10/head ($1500 in loss for the GroupOn).

If a place is doing a GroupOn it is unlikely a zero revenue person will displace a paying person, since the place would have to be almost at capacity for that to make sense (and if they're that popular, why are they doing a GroupOn?).

But then the real question is: "How effective of an advertising platform is GroupOn?" And that I do not know.

PS - Anecdotally I have read that the "type" of customer GroupOn attracts might hurt it further (people claim they're very demanding, hard to please, and unlikely to return). But anecdotes and anecdotes, have to take them with a pinch of salt.

PPS - I myself wouldn't do a GroupOn because I would feel like it was de-valuing the establishment. It sets the new "normal" to the discounted price.

> And I hate when people use efficiency when they mean speed.

Except they're usually right. "Efficiency" is not just a measure of algorithmic complexity. Something is more efficient if you are able to do more of a desired activity at the cost of fewer resources. The resource in question varies.

Yes, one often in computer science focuses on algorithmic complexity as the resource to be economized on. But time and power are also perfectly reasonable resources to have in mind. In fact, they are the resource that most audiences will naturally assume when they see the word "efficient" standing along, without further explanation.

I think GP is probably wrong to criticize as well -- making code more efficient [or, if you insist, fast] makes it easier to support more users that it could support otherwise. Is the ease with which a system can support an additional user not the very definition of the word "scalability"?

Of course, there are more powerful, and more specialized techniques for improving scalability, but that doesn't mean the author is wrong to suggest that speed improves scalability.

New Slack team for hardware startups support around the world, help us grow
Trying to build a network for hardware startups starting with real-time communication with Slack. Get invited here (might lag a bit since heroku turns off app after some inactivity, just wait for the load): http://hwstartup.herokuapp.com/

Who am I and what do I do?

Absolutely nobody. I don't have any successful startups under my belt or any of my own products out for sale. But this is what I'm trying to change. I'm just a simple electrical engineer who's always wanted to build my own company and grow the HW space.

What's the problem here?

I find that there's large barriers to doing a startup, and even more so if you're doing a hardware startup. If you have the technical knowledge, you have little idea how to get your product out into the hands of your customers. If you're more of a business guy with an idea, you have little idea about if it is design-feasible unless you find yourself a technical co-founder.
And probably most people are confused about how to mass production and distribution.
I want to create a community where we exchange advice, experiences, and contacts (optional) to try and create a better network for all hardware startups.

Why can't we just use the Reddit search function or Google?

Yes, we can all definitely do that. I've been doing it for years, but it's only really gotten me so far. Sometimes you just need to be able to message someone and say "hey, I need to do this thing, do you know anyone that can help?" and be responded with "hey, yeah, let me get you intro you to this guy" or even "hey, yeah my company/product/service can help you, let's chat more"
Or maybe you just want to ask a question and not be answered with "lolol that's never going to work" without a reason why it won't work

Let me know what you guys think about this in the comments.

If you have a better source, feel free to share it. This is a datapoint which strongly disagrees with your claim. It might be flawed, but that does not make it invalid. Do you have data which supports your claim?

That RMS says that you can use Apache if you don’t want copyleft does not support that it’s the most widely suggested. You can be sure that RMS will not suggest using Apache over GPL where GPL can be used.

There are less people who are opposed to Apache than there are people who are opposed to the GPL (or strong copyleft in general), but that does not mean that there are more people who would suggest using Apache than people who would suggest using the GPL.

Free Software proponents will say “I would suggest GPL, but Apache is still Free Software, so it’s OK”. This is not the same as suggesting to use Apache.

I think a lot of the hype and interest generated by Groupon is that they were very good deals for the consumers.

If they were just regular coupons, consumers would simply dismiss it with a "meh" and forget about Groupon.
You will have a hard time finding a place like this, because honesty and truthfulness do not perform well in large groups where there is not a pre-rational basis (e.g. religion or blood-ties) for them.

You should look for smaller companies for more honesty, but also recognize that there is another side of the coin: there will be a stronger ingroup tendency and it may be harder to gain trust, and there will be less stability in this economic environment, which can add tensions.

I worked for a company that started as a fairly small, high-trust startup of about 50 people and that grew into a huge public company. Despite the leadership remaining relatively constant, once a certain size was hit it became apparent that political management and power relations became more important than productivity. Honesty regarding mistakes, in particular, almost completely vanished.

I'm convinced that group size is the most important factor in trust formation.
That is a self fulfilling prophecy. It is quite ironic that a European company has devolved to committing fraud to try to get around stricter emission rules in the US.
You express what I consider an understandable but problematic sentiment.

The idea of the customer is always right somehow transformed into the fallacy of what is good for the consumer is good for the company.
Why does the economy have to be based on trying to get people to buy things they don't need? I think he has a good point about consumerist society.

Chicago dev here. Lots of friends in the groupon circle I know have been unhappy and left. Know two people at uptake, both miserable there. They seem to have a big problem with claiming/trying to be a great place to work, but executing poorly.
I think the better solution would have been to just disclose that it was a referral link.
I'd guess preexisting charges.

The time I took Amtrak cross country, my seat friend was "Ralph". He was nicely dressed, in the "import trucking" business, didn't like flying, and upgraded to a sleeper cabin with cash. The FBI got on at ABQ and started harassing people for their tickets. I was in the observation car at the time, but when I returned to my seat Ralph was still there! He had been hitting on the train attendant the whole time, and now she was giving him shit about the FBI's visit. He kept insisting they "just wanted to talk". I've no idea if he somehow successfully dodged them, or if they just wanted to scare him, or perhaps the train is a great place to do an exchange with an informant.

I'd imagine there's a lot of riff-raff (I use this word lovingly) on the train, because flying is hopelessly facist in the technical sense - eg that dance of responsibility that makes for the mandatory pervsearch. On the train you at least retain some skeleton of rights.

IMHO going West->East is the wrong way for scenery. All of the pretty geology up front, then flat nothingness for the remaining two thirds. At least this is my recollection of driving (I'm not even out of Colorado yet?!). Going East->West, there's a nice progression that keeps one entertained the whole time. But perhaps it's different to west coast native eyes as the green really starts filling in.
The value proposition with Groupon is largely that you are selling a limited deal at promotional prices (i.e., ones which you would not be profitable sustaining) to build business. It was essentially, when it was novel, a new acquisition channel.

Even business owners that new their margins wouldn't know its value to their business without testing it in their actual circumstances.

The water will just go around the wall. I think people don't quite understand the logistics involved. You have this massive wave travelling at 300 km/h. The seawall will break up the wave, but you have to have it long enough to prevent the water from reaching the bits that you want to protect before it retreats (often 20-30 minutes later).
