Uh oh, it doesn't mention head speed, or volume throughput. That's a bad sign. The frame doesn't even look as stiff as the Makerbot Replicator, which is pretty miserably slow compared to some of the bleeding edge designs. (ORDbot, Utilimaker) 3d printers with small motors and light frames can be excruciatingly, unusably slow.

It also doesn't say how large the cartridges are. Or how much they cost. It's also got a pretty small build volume, and a completely proprietary toolchain, including model files. (???)
For the first problem, you could test the generated selector to verify it matches only one element. If not you can use, for example, the nth-child pseudo-class to select the right element.

For the second one, specs say that the "id" value must be unique in the entire document [2].

I guess at 1959 there was no(not many?) computer science majors, and it might have been the norm for a mathematician to start programming, then.
The technology that will power the next round of innovation is under development on uninspiring projects. Think about how far browser technology has advanced in just the last few years. We're only just now starting to apply the processing and communication capacity created by the .com boom.

We need a break to appreciate how far we've come at least once a century. And this break is about to end. Appreciate while you can. We're about to see a repeat of the '80s, '90s, and '00s.

Tired of ad-ridden and bloated PageRank extensions for Chrome? Check this one.
It looks like this ascends the list of parents for an element to generate a signature. This falls apart if you move an element somewhere else in the DOM - a different signature, but it's really the same node.

IMO the best approach is still to use $.data('my_element', el)

I started with replaceState only, but later I realized there was no specific gain that I was having (other than slightly good looking string without hash). This method also suffers from reload and favicon flashes. If it reliably doesn't log to history (unlike location.replace()), using it could be a good idea. But that also comes with a tradeoff of older browser support issues, which requires using external javascript APIs.

10 actionable feedback for your startup
Hello HN,

We have revised our feedback process for startups so that all startups receive quality feedback in a timely manner and in the mist cost effective way. Here is how it works:

1. You submit your startup.

2.After your information is received, we feature your startup on StartUpLift.

3. We then email our users announcing your startup and invite them over for feedback.

4. Users start submitting their feedback addressing the questions you’ve asked and completing the tasks you’ve assigned.

5. You will receive thorough, insightful and actionable feedback from 10 different feedback providers. Of the ten, top five are selected for cash awards. Others receive consolation prizes. This healthy competition ensures the quality of submissions.

6.Your site remains permanently listed on StartUpLift (you may request removal.)

I look forward to your comments.
Absolutely, every place I have ever worked for avoids this kind of things.

The problem in automatically running "git submodule update" is that it might require network access, which may be down and/or slow. And the latest head might not be compatible with the rest of your software. Since there is no smart way of managing these problems, it's best not to do that implictly.
"I'm surprised"

When it comes to Google collecting information which would surprise the average person and would cause concern for the citizenry were there government do so, one shouldn't be. This is simply another example of what Google will do in the interest of "developing new services."
I don't agree that's less demand or incentive to innovations: big cost reductions and productivity improvements are still richly rewarded.

Yes inventing new things is increasingly more complex, but there are ways to decrease this complexity. there's no wonder that there is a huge amount of software innovation, since the software field is deeply focused on decreasing complexity and enables new inventions.
Yes. You got a valid point here. This does not gonna work for 100% for dynamically generated content. But should work for statically generated contents.

$.data('my_element', el) works if you everything works on the same page without refreshing the window. But I wanted a way to store the signature on a DB and make it highlighted at some point later.
Surprisingly difficult to find an arc interrupter in the UK. I found a link [0] which might shed some light on that; essentially the characteristics/problems of a 240v grounded system are different to a 110v, predominantly 2-pin system.

having a controlled state for foreign repos is absolutely essential.

But, you don't need to sell to everyone. Just find a group of people willing to support whatever your tastes dictate you create. When your interests don't seem to mesh you can always create a pen name to sell keep differentiated fan groups separate.
> But if the content is changed dynamicly we might face some issues.

Regardless the problem I was raising, if the document changes dynamically, your generated signature has great chances to fail (cf. also comment from bdunn).

> in reality developers do not adhere to [2]

I really hope it's not true because it would really be quite pointless. Let's try by yourself: put the same id name (e.g. "testId") on two different elements in your example and then try this code:

$("#testId")

It will return only one element. So you'll never be able to find the second one with a selector...

Agree with most of the posters, that Git submodules are very hard to work with.

The key to submodules is that you should not update them on a regular basis. A good example is the Gitflow project that uses the shFlags repo as a submodule.

A small gotcha is that you need to use --recursive when cloning the repo, so that you get the submodule cloned as well.

As a non founder think of it in terms of what your (worth to the market - what they actually pay you) * risk your willing to take. So if you can get a job at Microsoft for 110k + 25k in benefits, and the start wants you for 70k + 15k in benefits then your giving up 50K in salary per year and you need to get enough shares (which are probably worthless) to make up for that * the number of years it takes you to vest.

As a yardstick I would aim for 1.5x the rate of whatever the last round of investment was. AKA if they got 5 million and your giving up 50k then look for 10% of whatever the investor got vested over 3 years. (Also, the further from your market rate the shorter your vesting schedule needs to be.)

PS: Don't forget the idea is paying you in stock needs to be more expensive than paying you in cash or they are going to want to pay you in as much worthless stock as possible.

Had the same issue on my work netbook, it was getting slower. Then I "cleaned up" Xfce, removed a huge desktop background image, switched to a lighter window decoration and button theme, and that helped a lot. Not Xfce it is fast again. Just saying, sometimes its not the software but the layout/theme that fills up the memory (at least on my small 1GB netbook).
Very good article. The question is, will it ever be fixed?

As it stands submodules don't even work sanely for the most trivial use-case of tracking a (slow changing) vendor-repo.

I found CircuitLab a few weeks ago and was impressed with it. I have little need to simulate simple circuits with discrete components - what would be amazing is if this could be the start of a system that could include micro controllers - in my dream world these micro controllers would be programmable with the code you would write if you had the physical micro controller and the simulation would allow you to fully prototype an embedded system without having to fight with physical circuit issues (like: oh crap i've put this transistor in the wrong way round - that's why it's not worked for the last hour).

Sadly I don't think this dream solution will ever exist - maybe just for a PIC16F690 or and mbed?

Just replied to your comment on GitHub. I appreciated the official response.

Like I mentioned on GitHub, your updater is broken, so your customers aren't getting this update even if you guys did release it. See my comment for details, but it appears that the file which triggers the Update Framework feature to work has been rolled back to an old version.

Regarding your comment on 'responsible disclosure', where did you responsibly disclose this exploit to your customers and notify them that a critical update was needed to prevent, in your words "a way to cripple many (many, many, many) websites."?
Apparently it wasn't fixed (or at least the fix hasn't been released to customers yet): https://gist.github.com/2523147#gistcomment-288527

I spend my day building a castle in my head. Sometimes I may go outside and pace around the parking lot, sorting through the rooms in that castle.

I drink 10-15 cups of whatever a day. The cups get tossed in the trash when empty, or left ..somewhere.. when I get an idea.

But stop me every time my cup is empty, make me break my train of thought and go fool with soap and water and a breakable cup? Likely the castle comes crashing down, and 40 minutes to rebuild it.

Might work for some, but definitely not for me. Wash your own cup; but leave me alone.

I really wish that I could remember the article/movie/show which I read/watched but it was talking about creating a universal language.

This would be not just for people living on Earth but also life outside of our Solar System. It would make sense that if there was a universal language that it would be based around some mathematical form. At least something which should be constant through the universe.

Gore divides the company into business units, each in their own building with their own parking lot and staff. In fact, they know when to divide a growing unit - when people start parking on the grass (the parking lot gets full).

So no not 9000 people; 90 units of 100 people ( or something like that)

Roads, sewers, police and fire are dirt cheap. Bringing them up is disingenuous.

http://www.usgovernmentspending.com/year_spending_2010USbt_1...

As for the federal road system, that's paid for by gas taxes - Apple (or fedex, or whoever delivers iPhones) pays for it whenever they fill up their gas tanks roughly in proportion to how much they use it.

It's also hardly clear that businesses are not paying their share of the burden. The services businesses require cost very little - corporate registration, police protection, roads, etc. The fact that these services are cheap is demonstrated by the fact that Nevada provides those services and charges very little for it.

Most other services are given to individuals and different individuals (usually younger ones) are charged for those services. The individuals who work for Apple raise their prices commensurately.

There are thousands of ways to implement Microcredit, and some implementations have been in ways that were already proven to not work very well. But to make money.

Yunnus/Grameen had some good ideas (read his book) that are not really about the money they give out to poor people. The money is only a way to get the poor people to come to the meetings regularly and follow certain important principles, like "all my children go to school" or "we eat every day three meals" or "we will try to build a stable home made of bricks/tin roof" etc.

Seems trivial, but those are important steps. Not to mention the fact that many Grameen credits are given to groups that mutually guarantee their credit! If one person fails to pay back, the others have to pay back for this person. People learn by that to work together and to trust each other (building social capital, the very basis of every lasting economic development, read "F.Fukuyama, Trust - Social Virtues and the Creation of Prosperity" for example).

Just handing out little credits will of course not help a lot, but in some situations it may help, so its worthwhile anyway.

A next important step would be to make laws in all countries that banks /have to/ give one free savings accounts to everybody. No credit account of course, but a right to have a bank account would be an important and easy to implement step.

The code could, at the very least, be using $_POST. Yes, that wouldn't stop it, but it would make it harder to execute via naked URLs (assuming that's the exploit going around, which I think it is).

This is precisely why I do not like $_REQUEST, and counsel against it in presentations/classes I do on PHP. This is clearly written to be something which modifies state - GET values should be ignored in this situations. And yes, again, it's not perfect - someone could craft malicious POST requests - I know - but that requires an extra level of effort not currently needed, and it's an extra level of effort some people won't bother with.

I see. Surprised to learn there were still issues as replaceState() (as with pushState) is purely a transformation in the URL path. There's no reload and no update of the favicon link tag. Makes me wonder if that's a browser bug you saw.
As for me, I'm all for it, especially since today's technology makes this possible!

However, I'm still against the extreme measures mentioned by OP, like dropping any other income and feeding yourself with your work. In such situation it becomes hard to distinguish whether you really just found your target audience, or you needed to subconsciously alter your taste to suit their taste because you were running out of money.

Apart from that, it's just that the prospect of living off the support of few people—who are free stop paying any moment—seems a bit risky to me personally (I know I'd abandon any authenticity and start making what people want in this case).
