Charging was definitely the biggest problem with the Roadster. If you want to drive from Berkeley to Mountain View and then back, the car has to charge for a good 3 hours on the fast connection while you're in Mountain View or you risk going dead. The Roadster nominally drives 200 miles on one charge but it was more like 140 unless you're going downhill the whole time.

I'd heard rumors of Stanford letting you charge without plugging in while driving past the campus- that would be awesome.

A5 was manufacturered at 45 nm for the iPhone 4S, and had a 70 sq mm size.

A6 was manufactured at 32 nm, so 30% improvement, and the chip is also 97 sq mm. So another 40% improvement.

Let's say the new architecture brings say 40% IPC improvement for the CPU cores, like A15 cores do over A9 (could be less, could be more).

Then the new cores are also clocked at 1.2 Ghz (according to Anandtech's tests, ifixit doesn't seem to check this, just goes by the rumors), that's another 50% improvement over the old CPU cores.

The last 2 improvements alone could make the CPU's speed 2x over the iPhone 4S's CPU, while the first 2 types of improvements could've been used to introduce a larger GPU (3 cores) and at a higher frequency (thanks to die shrinkage).
Flexibility is useful in development. Once you deploy then things will change less frequently so the real benefit is when you do have to change something, you're not running a big ALTER statement.
Well, I know what I'm buying.
Agreed, Rob Pike, in his search engine example at Google's I/O 2012 IIRC, made the explicit point that mutexes are there and that channels are for joining large concurrent parts of the program together; guarding a data structure seems too small even though it's a common (toy?) example. http://www.youtube.com/watch?feature=player_embedded&v=f...

So far the new version seems to have improved on this.

It is indeed broken. A fun daily ritual for me has been to surf new releases using the 'release date' tab. This is how I find my apps. Some of my favorites have never been on the 'new and noteworthy', 'editor's choice', or 'top...' Charts. I don't give a rat's ass what some crap algorithm or hipster-douchebag-cubicle-jockey-apple-employee considers worthy. Maybe this is a good thing as I spend way too much money in the App Store.
Just to be clear... that's a good thing, right? =)
I built a simple dictionary - thoughts and feedback are welcome
When I read, I hate to be distracted. I found that using most online dictionaries is frustrating because you have to mentally block out ads, pronunciation info and etymologies, Google results, etc. I wanted something with as few words as possible. The Mac's built-in dictionary was OK, but when I switched to PC I knew it was time to make something.

I think people put way too much faith in inbound TLS. My mail server has some bozo self signed cert and nobody has ever failed to send me an email. Meaning: either nobody is using TLS to deliver mail or they use TLS and ignore all cert failures. Either way, about 99% less secure than you think it is.
30 minutes is already a vast improvement over the old technology which took hours, maybe 6 hours if you weren't on the fast connection, or I heard days if you were stuck using a normal outlet.
It's hard to reconcile with the idealized version of the http://en.wikipedia.org/wiki/Night-watchman_state that does nothing more than enforce the non-aggression principle. I suppose one could consider arson (not accidents) as a form of aggression they must be prepared for, but I find this an obvious public good the night-watchman state doesn't account for very well.
Good point, but of course installing a decent browser is the counter argument. Admittedly my 3 year old Nokia may not be very representative, but its Opera Mini version solves that problem beautifully. My hunch is that it uses heuristics to find the main text area (which nearly every site has), and adjusts the css of that block to $SCREEN_WIDTH. It's been able to do this ever since I started using it in 2009. Now, I've lived under a rock since then, but are you really saying that your mobile browser doesn't do something like that?

I believe it's such browsers that the author was referring to.

Still, admittedly, using heuristics to patch the css shouldn't really be a browser's task, so your point holds.

I read about this charging issue being addressed in Israel with a company called Better Place that does battery swapping. The reasoning was Israel is small enough to roll out something like this on a large scale. Battery swapping sounds great because they were saying it'd only take a few minutes, which is comparable to fueling up with gas.

I think it's an admirable goal, but they have a huge task ahead to convince both developers and other browsers to pick the standard up.

The space & time thing is a joke. Because we're nerds, we have trouble with clashes between literalism and humor. He is saying, the behavior of a function depending on its return value is like the past (the execution of the function) depending on the future (the storage of the result of the execution of the function).

In the enterprise world (at least in the Microsoft world) we have tools to manage these sorts of things. The one I'm currently using even for my small pet projects is called SQL Server Data Tools[1]. You basically just have to modify the original table creation scripts (add a column or whatever) and it actually generates all the change scripts for you. Even if the change is complex it handles making temp tables and transferring the data into the new table. It also notifies you and lets you handle cases where the change may lead to data loss.

I guess my point is that the SQL world is still innovating but it doesn't get that much attention. Unless I have a specific use-case for storing similar entities together with different fields then a schemaless DB is not the right tool for the job.

What Developers Want
I for one can't read Facebook's timeline and that uses downward scrolling. I don't quite get why I find it so difficult. I really can't get on with it. I'm fine with one column (but two - is a complete mind warp for me.)

It's probably an alignment issue with my brain scrabbling to differentiate content.

I'm also a fan of paging over scrolling. So it will be interesting to feel how this works. Perhaps scrolling with the finger lets you focus better than scrolling with the keyboard or pointer.
I have come to the same conclusion. I don't understand why we keep voting with ballots and not feet.

Does anyone here remember those vertical cities (they were effectively cities) in SimCity 2000 (3000?)? I can't find a picture (EDIT: found it: http://imgur.com/MBAzs) but ever since I first played that game, that tiny pixelated picture has given me many ideas.

Think of a large building with everything you need inside - all big box stores, small businesses, and residences. But in order to live there you need to share a lot in common with the philosophy that building was made for. So there would be one for liberals who are for abortion and for legalizing pot and so on and so forth; there would also be a separate building for all of the tiny variations, and those buildings would literally undergo a kind of natural selection (people would choose where to live) and the least popular ones would keep fine tuning their philosophy to try and attract more people.

That way we would all live with like minded people, there would be a lot less of the problems there are in today's society (basically all the proselytizing and wanting others to do as you think is right for them).

I'll stop here because I'm saving this stuff for a book or a long article, but Jacques article and your comments here have just alerted me to the fact that there might be other people who think the same as I do. To be frank, I'd much rather have a beer with you all than waste my time typing this crap. We could all do that if we lived in one of those vertical charter cities. :)

The Hacker Employment Contract
Once someone has access to your e-mail, they can reset your password and log into anything that you used that e-mail to sign up for. With Dropbox, all they'd have access to is whatever files you happen to have in your Dropbox at the time.
I don't think that's particularly notable. They certainly aren't saying someone manually drafted each of the (dozens of!) mask layers on paper. They're saying that the floorplanning (i.e. the positioning of individual subcomponents into rectangular regions of the die) looks like it was done by a human being instead of a synthesis algorithm. I'm not chip designer, but I'd expect that would be routine for the high level components of a big CPU. People can make better guesses at the gross level because they know what the design "means".

To clarify, the bad incentives would be that journal would publish lower quality papers to get additional revenue?
The payment processing fee structure almost incentivizes these customer support nonresponses. If I'm a small company experiencing technical problems with payments, I'm losing ~95% on each error while the payment processor is losing the remaining sliver. For a startup, these sales are critical, but for the payment processor, the fees on these low volume transactions are chump change. I can only hope a bigger customer is experiencing similar issues so the bug fix can be expedited. My only recourses are switching payment processors and generating some bad publicity through a blog post.
Good pricing change ... I was hesitant to try this out because I already have an S3 upload option and the old pricing plan had S3 upload only on the $50/month plan. With the free plan I can try things out without having to start paying right away — very cool.

The GMail integration is awesome as well — I can see my clients really liking that.

Going to have another look at this. Nice work all!

Chief Infrastructure Hacker  GAP Inc 
If you have the skills we want, both 10-year IT veterans and fresh college graduates are welcome.
Strong working knowledge of key infrastructure towers: Servers, Storage (SAN and NAS), IP networking (LAN, WAN, load balancing, Voice), and Security.

The candidate will help Gap transform its infrastructure with the most modern “DevOps” style approaches using open source software as well as carefully selected commercial solutions. He/she will also be responsible for helping the Director of Infrastructure Architecture hold engineering design sessions, hosting hack-a-thon events, and act as a proxy in cross-organizational functions regarding architecture. The candidate will work closely with all infrastructure towers to develop open source solutions that Gap can share with the community. In this capacity, the position is free to develop and test any and all relevant bleeding-edge and mature solutions in the marketplace in cutting edge data center environments.

This is both a highly hands on, deep engineering role we well as an evangelist and technical thought leadership role. Get all the benefits of working at a startup as an open source infrastructure as code Jedi without the startup company risk. This is a rare and unique position for a truly talented hacker that is looking to be empowered to bring the startup ethos to an iconic American company with a vibrant, creative culture.
Probably because of this CBO report on the Chevy Volt. See

As the article states, the first-gen Gorilla glass was manufactured in a very advanced facility in Kentucky and shipped to China for polishing and cutting. The Kentucky factory had been in existence since 1952.

As this article

http://www.kentucky.com/2012/04/16/2152727/harrodsburg-produ...

states, the manufacturing of subsequent generations has gone to factories in Japan and Taiwan. But the Kentucky factory is still expanding. According to the article, the average wage of a new set of added jobs was $25/hour.

I don't see what the problem is. Any time engineering advances like this yield exotic materials with amazing and useful properties, we technologists should be appreciative.
> I think a lot of the "hating" is a side effect of MongoDB being consistently oversold in terms of its capabilities and architecture.

Agreed, though I think its also coupled with just a lack of understanding of what MongoDB does beyond just "its NoSQL!". So many people are used to working with RDBMS. They just seem to make incorrect assumptions about MongoDB based on what they thought were universal rules about databases.

Mongo's a tool. Its not right for all situations and it definitely has some maturing to go still, but its good to use in certain situations, provided you're properly informed about it.
Maybe we should bail them out?

I cannot speak for the UK (I've never done business there) but becoming a freelancer in the US is very easy. You can incorporate effectively online for a few hundred dollars, and in your first year, if you don't have the revenue to justify an accountant, you can do all the tax prep you'll need online. Again, in the US, most of the stuff in consulting agreements protects the client, not the consultant.
> Let's say the new architecture brings say 40% IPC improvement

"Let's say" ? Surely this is something that can be trivially measured just by running a benchmark. Has one been done? Note that 40% seems pretty optimistic, considering similar bumps in transistor counts in the Intel world generally get about a 10% benefit (you can do better by adding more cores, of course, but squeezing instructions through a pipeline with transistor logic alone is really hard).

Also: your analysis is off. Transistor count scales linearly with die area, but as the square of node size (not quite, as the transistor layout changes between processes, but it's still a linear, not areal metric).
I agree 100% about avoiding the self-promotion nonsense, but I would make the following exception for "that wine guy" (Gary Vaynerchuk): his wine videos are terrific! I learned a ton about wine and the wine industry from http://tv.winelibrary.com/ (and later, http://dailygrape.com/) when he was still actively producing videos, and I was extremely disappointed when he stopped doing this to focus on being a "social media expert".

What I like is not the absence of a schema (because as you say there usually is one), but not having to fit it into the 2D SQL table model. An obvious case in when you have a many-to-one field that only ever contains a small number of values (e.g. a person's nationality); in a traditional SQL database my choices are make a separate table for it, or use a database-specific custom datatype (which never seem to be fully supported). In something like mongoDB I can just put a list in that field of the document.
Headline problem: Deployed on 32 bit server so was limited to 2GB database. Writes were being silently discarded.

Mistake: Deployed to 32 bit servers without knowledge of the limit. Did not use safe writes and didn’t check for errors after writes.

Sorry, I just do not see eye-to-eye with anyone who thinks this problem was the mistake of the user. This attitude, though detestable, is prevalent in our industry, and it's wrong.

The database was silently throwing away writes. I don't know what else to say.

I mean, I'm sure that MongoDB is really great for some people, and that it's doing a really awesome job storing their data. That is, until one day their writes start silently failing, because they neglected to check a priori every instance in which Mongo would silently fail. Which would make it their fault, naturally. I'd rather not find myself in that situation, but different strokes I guess.
Let's try to avoid at least half the unnecessary comments on this article:

Sometimes we just need to hear the opposite to do the right thing. :-)
With 400GB of data I'd imagine you are going to be ripping your hair out at some point or another regardless of what database you use ... there is no way to completely avoid tech issues over the lifetime of a product/service.
It's not just that the defaults are dangerous, but that if you change the default, you give up much of the performance benefit of choosing Mongo in the first place.
