Information Saturation
I think the 21st century has a big largely unnoticed problem; the saturation of information, which is "to destroy (a target) completely with bombs and missiles.", but with opinions instead of bombs and 2nd hand facts instead of bombs.

I'd rather discuss my opinions in the comments, but I really encourage people interested in this to watch these to video that talk about the issue:

Ruby 1.9.3+ justifies the major version bump
I think this relates a lot to the discussions of censorship and moderation we've been having the last few days here.

My opinion is that without perfect mods, censorship has potential for harm and abuse, but on the otherhand, so does not doing anything at all.

So I guess I don't know what to think. I'd love a meaningful hackernews discussion on this. Let's hear your thoughts (after you've watched one of the videos of course, or I we might not be talking about the same, larger issue here).
From what it looks like to me, it's not so much about a drastic new feature set but rather about trimming down dramatically. You could argue that it really should be like 3.2 -> 3.3 similar to OSX Leopard -> OSX Snow Leopard. I think they gave it a full version upgrade because it WILL (not might) break a lot of apps. That's my interpretation. I might be wrong.

Happy user of both Heroku and (recently) GetSentry here.

I think the author may be undervaluing how useful it was to, "for the first couple of months", survive on the off-the-shelf offerings. He didn't have to spend 3 days learning server configurations. He could instead expand his service "to cover nearly all popular languages".

He only had to switch -- spending effort on researching alternatives and learning new systems -- after knowing the growth path of his business, the pain-points of his architecture, and the baseline costs of a cloud solution. Heroku's turnkey environment, warts and all, got him to the point where he knew enough about his business situation to make rational optimization changes.

And if the 'shape' of his architecture, growth, and personal expertise was slightly different, he might be just adding dynos and upgrades inside the Heroku system today, happy to be paying them far more than his peak $700 cloud bill.

The experience at 2 years is quite a bit different than the experience at 2 months. Startups have life cycles, some parts of which are much more stressful than others for startup CEOs. It does not become easier over the first few years, quite the opposite in most cases.

Doing something cool is why we do it but as startups grow the challenges of that growth can start to take a real toll on the founders on many different levels. That part is not particularly fun even for people that feed off the stress. Startup entrepreneurs do not complain about it -- it comes with the territory -- but it would also be foolish to deny the true costs of our chosen lifestyle.

I am not an entrepreneur because it is a healthy lifestyle or an easy path to wealth, because it is neither. I am an entrepreneur because that is what I am and I could not imagine being anything else.

I agree. It would be a bad idea to have a stack of metal equipment all plugged into floating outlets. You'd be likely to get all kinds of weird voltages between the metal cases.

The electrocution hazard was just one way it was the bad old days. It also sucked for other kinds of signals, hi fi, radio, etc. I would not want to try to have a home office full of computer equipment that weren't sharing a common ground.

Did you ever have one of those 17"+ CRT monitors? Recall how they would make the hair on your arm stand on end when you turned them off or on? Without a dedicated ground for those things, guess where all that charge is going to go? Into your computer, via the ground on the signal cable.

Congratulations on winning the Hackathon! Did you participate in the December Finals in Palo Alto and this blogpost is just many months late, or have they started a new round competition? If it's the former, I believe we've met (I was on the UW team), if it's the latter, best of luck!

My experience at the Facebook Hackathon was very similar - I was the only Freshman to enter, our team had been cobbled together entirely by chance (2/4 were found by posting on reddit). We were some of the last to demo, and every one that preceded us seemed, at least to me, far more technically impressive. People had built real time games, written web-servers, designed Android apps to handle streaming video, but (almost) no one had a use-case. We essentially strung together API on top of API in some of the most hacky code I've ever written[1], and somehow it all came together in the end to a) work for the demo and b) seem like something people would actually use. Our idea for the final round was far more derivative and banal, and we lost because of it.

I may have had it a little wrong. I can't find older legislation about this subject that confirms my supposition.

This 1994 legislation made it the law that plugs must be fitted to certain consumer devices: http://www.legislation.gov.uk/uksi/1994/1768/contents/made

Before that time, almost everything (certainly everything I purchased) came without a plug and you had to buy a plug and wire it yourself. Probably because these things are expensive, and costs could be reduced by leaving them out.

Ask HN: What do you look for in hiring Interaction/Product Designers?
(Sorry for the anonymous account).

I'm an interaction designer for a consulting company and really want to move into product design. I'm new to the field (1-2yrs professionally, on and off web design for a number of years), and while I'm totally a self-starter and constantly trying to learn new things (languages like Python and Ruby so I can build my ideas) I often feel inadequate because many listings ask for product design experience.

I have a personal project I'm working on now that I can eventually point to and say 'hey look, I'm working on it' but nothing this moment. My current job has me working on ecommerce design, which is sometimes fun, but a lot of the time repetitive.

What can I do to sell myself with no product experience?

It's "Judging", not "Judgemental". It doesn't mean the same thing.

"Judgers are very organized. They like to "plan their work and work their plan." A Judger likely has a day planner or if she doesn't have one, she carries one around in her head. Work is carried out in an orderly fashion. Even holidays need to follow a plan."

"Perceivers like to go with the flow. If they have a "to do" list, it will likely be just a scrap of paper. They are always looking for new information."
I don't think making it mandatory is necessarily a good idea. But I would love to be able to have people give me a short reason for an down vote so that I can hopefully see what I'm doing wrong. Anonymously of course.

One issue I could see happening would be people abusing the feature to send hateful messages. Some solutions may be to allow users to delete messages or block the ability to give them text feedback along with a down or up vote.

Another problem might be causing a sort of hugfest where users try to get upvotes by upvoting someone else, creating an upvote ring. (Eg: Including their name in the feedback and asking for upvotes.) One countermeasure would be to block the user from putting in their unabridged unedited name into the feedback box. (Of course, this could be circumvented in the way that almost all other online censor systems are circumvented. Obfuscation.)

The truth is that there is an observation bias at play where people that are negative about experiences go to do that and people that are positive go to other places to do that.

The truth is that as CEO the buck stops with you, for good or bad.

How you choose to experience that is a whole other story. I for one find it more empowering to take this view that you are in control as CEO and to be accountable for your actions.

I know that doing this is hard, but it is no different to everything else where you have to be the best of the best. Blackbelt in martial arts, number 1 hit in the music charts, award winning tattooist, academy award winning movie director. It's all hard work and you never know how hard until you DO it.

The closest thing I can think of to it is probably having a baby:
does it change your life?
Is it harder/different than you thought?
would you do it again anyway?

If you answer no to any of these then you will probably make a bad parent/CEO :)

Because the goal of TSA is not to get a rid of terrorism or truly make you or me be safer; they are in business of making money and trying to make you _feel_ safer.

Dealing with Federal agencies on different levels (once I was very close to suing director of FBI; had writ of mandamus almost finished, but family forced me out of it) over last 8 years, I will tell you just like outside government, also inside government there are agencies more or less sinister. For years now it was CIA with infamous drug trafficking and prostitution, but comparing to good ole days, those are the good guys now. TSA is in business of scaring people because its like any other business - it wants to make money.

Folly (acronymed loosely after Facebook Open Source Library) 
Folly (acronymed loosely after Facebook Open Source Library) is a library of C++11 components designed with practicality and efficiency in mind. It complements (as opposed to competing against) offerings such as Boost and of course std. In fact, we embark on defining our own component only when something we need is either not available, or does not meet the needed performance profile.

Performance concerns permeate much of Folly, sometimes leading to designs that are more idiosyncratic than they would otherwise be (see e.g. PackedSyncPtr.h, SmallLocks.h). Good performance at large scale is a unifying theme in all of Folly.

They fail because they're not losing sleep over how well they execute their sales funnel.

As someone who is losing sleep over the same issue, I appreaciate the fact that you understand it. I never get why so many startups focus on the minor things when the sales funnel is the most important part of the deal. Seems like people are just doing startups because its IN. Not because they want to build a profitable business.

One set of preparation can be good for more than one opportunity. E.g. Saving up $100k, which can be used for the following opportunities: Housing crisis, stock crash, initial investment in a startup, travel. It can also be used for the following unfavourable circumstances: sickness, accident, personal reason for travelling. A more narrow form of preparation could be learning a skill, e.g. programming, which sets you up for possible startup ventures as well as a full-time job.

He's not saying that you shouldn't try to seize opportunities when you may not be fully prepared; He's saying when opportunities are available, you will be more able to seize it if you're more prepared.

Gmail does better than most alternatives for antispam. It's pretty good for deliverability (although it's actually kind of bad for receiving mail from semi-sketchy places; it doesn't even go into my spam box).

It's a slow UI (I often see 20-30 second page loading times on a fast network, over SSL), the support on the free tier is horrible (i.e. non-existent), the $50/user/yr support is below what I'd want for a company to rely on it (it's ok as second or third tier support for your in-house people, I guess, but not great frontline support for non-technical users when traveling).

The real killer, though, is lack of the enhanced features Exchange offers for directory, scheduling, etc. I always hated people who depended on those kind of things, but once I started using them, it made life annoying to not have them. Google Calendar and Google Contacts are feature-incomplete and often buggy (syncing to devices, other than maybe Android phones), especially when you have multiple calendars, sharing, etc.

It's all fine for individual users, but for a group of 5-25+ people (startup, pe fund, etc.), using google apps often sucks.
That is neither the expected nor the standard use case. If you use a product in a way it's not designed to be used you shouldn't be surprised when it's behaves in a non-ideal fashion. Notifications and auto-update can be disabled.
The http://highscalability.com/ blog has a decent archive on the topic. Remember that your situation is unique and that the first rule of scaling is to measure everything you can. No two sites have the same audience, or requirements, or expectations. Things that work in one context will only create problems in another, and the context will change over time.

My own experiences tell me that the important things are:

1. understand http caching, and how to make it work for you.

2. query caching (whether against a database, a document store, search engine or what have you) buys you more than tweaking your web server.

3. your webserver configuration matters, but not as much as you'd think.

4. chunking a stream and sharding a datastore are two different views of the same problem.

Yes, the purpose of RAID is not to fail silently; but it's hardware, and hardware can be flawed. That's just a fact. There are different levels of RAID precisely because there are different levels of redundancy - that is, different extents to which the possibility of failure is minimized. No hardware is flawless, though.

Please note that I have not said "it is likely to fail" or "you should expect that it will probably fail." I agree that it shouldn't be something that keeps a person up at night. But the simple fact is that, when data is important, you should prepare for that possibility (and others) by backing up. RAID does not solve all problems, and it is not guaranteed, as unlikely as failure might be.

Moreover - in saying that it simply isn't RAID if it ever fails silently, you're attempting to define away a nonsemantic problem. The point of a starter motor on a car is to start the engine. If the starter motor fails to start the engine, I guess I could make an Aristotelian argument that it has ceased to be a starter motor, or even perhaps that it was never a starter motor in the first place. But what practical good does that do anybody?

All hardware has the potential to fail. Yes, people should buy hardware that is less likely to fail. I'm pretty sure they already do that, though.
Geofencing works off cell towers. Since the cell hardware is already tracking towers anyway, the additional cost is minimal.
Does that mean the output of the transformer have no difference of potential relative to the ground? Why is that?

It must be for the same reason that an electric shock from an ungrounded AC circuit doesn't travel through your feet as the article mention.

But I'm having difficulties understanding this concept. My (admittedly naive) understanding of electricity is that when one terminal has more electrons than another you can wire both terminals to a light bulb and it will light up. i.e. electron travel through the light bulb from one terminal to the other.

If my understanding was correct it would mean that one terminal from the input circuit of the isolation transformer (the neutral wire and the ground it is connected to) would always have the same number of electrons than either terminal of the transformer output.

Since the reason we have an isolation transformer is to prevent electrons from traveling between the transformer output and the ground, both outputs and the ground need to have the same number of electron. i.e. zero voltage. Right?

Is there really no voltage at all between the two circuits? I find this confusing.

Hmm,

I recently created a private memory allocator so the discussion on the page is somewhat interesting...

Only a tiny minority of objects are genuinely non-relocatable:

Hmm, I'm not exactly what is meant here. Moving a block of memory from here to there in the most general case will leave your pointers dangling and crash you in no short order. Things that pointed to the data you moved just don't any more. If you are disciplined and don't have raw pointers in the block moved, you're good. But as far as I know, that situation requires a very complete understanding of the data in the block you are moving. You can do that. It's just not easy or something that makes sense to stuff "anything" into.
