If you ask for demographics you will not only get increased abandonment, you will also get a lot of incorrect information, would it surprise you to know that I'm a 95 year old sumo wrestler? Your users don't care that you will get higher advertising rates due to "ad-target specific demographics". Don't ask for demographic information unless the user can see how it will benefit them directly. Facebook gets peoples correct birthdays (most of the time) because if you put in the right one, you get birthday wishes from your friends.

A normal car engine unused for a long time has to be handled just as well. If you're lucky the worst you'll have is a dead battery. If you're unlucky the engine has seized and the tires are deformed and need to be replaced. Ask any university town mechanic what happens when students leave cars parked in the lot, untouched, for months.

Actually as a former car owner (city dweller now), my biggest concern was making sure the car was still there when I came back later.

Really the biggest responsibility this car has is for the owner to keep batteris charged up, not check the oil, not check the coolant, nor check the break fluid or transmission fluid. When did spending a lot of money on a car mean you could also switch your brain off.

Yeah, and even if its a 1.0 thing that they expect to perfect over a couple versions, wearing something on your face does a lot to your sense of identity. It needs to look right, which pretty much means it needs to be well-designed — not Google's strong point.
Thanks. This is really helpful. I have been thinking about the concept of valuation model, but in a different wording (like previous commenter esun told , our revenue is between X and Y etc). I guess asking them to provide some kind of valuation based on what their growth strategy, assumptions on existing revenue are will be more helpful indication whether they are serious, rather than extracting deposit which may be discouraging and also legal burden for them.
What could possibly go wrong with individuals being tracked to this level? Don't be naive.

The response from Tesla does not contradict that notion. Note this quote: "It's true that a full discharge to zero percent state of charge can potentially be damaging to a battery. " Notice that "can potentially be damaging" is a weasel phrase for "brick". Further Tesla argues that to avoid discharge to zero percent "all that needs to be done is to tow the vehicle to a charger". Again, this misses the main point of the OP -- what happens if the vehicle doesn't get towed to the charger. The OP argues that then it discharges to zero percent which in Tesla's own words will be potentially damaging.

Tesla's PR people are particularly misleading by comparing the situation described above to someone draining oil and then taking a car on a cross country trip. Draining the oil requires action by car's owner. Leave a car in a garage for six months and the oil will still be there. The whole point of the OP is that inaction destroys Tesla's vehicles.
Perhaps you already know this, adding ?v=0 to the end of the URL to see the older version. I even drafted a quick Greasemonkey script for this, but it would need to run on all domains, as some of those blogs have their own domain name outside of blogspot.com
It contradicts it, but which account is correct. This new blog post says 'you just need to re-charge to fix'. The original post says 'you just need $40,000' to fix.

The orignial post appears to have better sources than this one, so I would say that it has been contradicted, but not refuted.

I have a friend who is almost blind. Nothing wrong with his eyes. It is his visual cortex that has the problem. Can't be corrected with lenses.

I think this type of technology will be of great use for people that have this kind of genetic deficiency.

As an example. Currently my friend uses an iPhone to take a picture of a menu, holds the display a few inches form his eyes and zooms in on the picture to read the menu.

I think he could use these glasses to stream zoomed in video and actually see what is going on around him.

FWIW, my Firefox privacy add-on stack is:

Yes, there is some overlap in functionality. And getting the configurations correct can be a minor pain (none of them are ready to go after install).

I have also found the Chromium version of Ghostery cannot be configured to block DoubleClick tracking. :-( So much for using Chrome-based browsers as my main browser.

I think I need to clarify my statement here.. By saying "open EU market a bit too" I meant that I think it is beneficial for European startups and entrepreneurs wannabe if they know they can easily apply for programs like ycombinator and bring their knowledge and product back to the mother land once the program is over. Of course there are a lot of programs that deserve consideration in Europe too, but I am sure everyone likes to have the full choice available instead of picking something just because it's closer to where I live or I want to.

This is begging to be explored further. If camera or other technology-induced artifacts can be ruled out, and there is indeed a provable link between the basic form of the object and the structure of the KB, then how would the basic form of the KB reflect whole classes of objects? Would it be possible to build a whole 'genome' of Klein bottles corresponding to types of objects? And if so, to what extent would the shape hold up to different lighting conditions, backgrounds, blur, exposure problems, parts of the object or picture missing, edacted or damaged, etc. Finally, can the results (again ruling out artifacts) shed some new light on how, say, the brain sees, or making computing devices process visual information better?

Oh, come now; everyone here has more imagination than that.

I feel like our brains have already rewired themselves somewhat since the web got really ubiquitous. I find it fascinating to consider a greater magnitude of constant information, meta information, facts, distractions.

Technology is neutral. Some of us made lives we wouldn't have without the Internet. Others have gone missing, lost in cyberworlds devoid of human touch.

It will be incredible to see what happens when the next interface allows each of these directions to flourish. Google Goggles are a hop and a skip down the path if you ask me.

"Don't rewrite" seems like pretty good advice.

Can you make a case for "write a new product that will (eventually) replace the old one?" After all, you know a lot more now from having written the first one. Write one to throw away, and all that.

Or if you write an X, are you forever discouraged from ever producing another, better, more relevant X?

>I don't intent to block ads

May I ask why? I can understand whitelisting domains who you regularly visit and use (and thus want to support with ad income) and whom you trust to serve safe and unobtrusive ads , but I would be going insane without ABP on the web. It's excruciating to use a browser without ABP installed. Imagine trying to hold a conversation with someone while at least half a dozen of people are screaming nonsense at you - that's how it feels to browse the web with ads to me.
Explain, and while you do, remember that "slippery slope" is a logical fallacy.
Awesome; if you could add syntax highlighting I think this would be pretty dang perfect. Navigation is much easier.
My understanding of what this post meant is that a full discharge is prevented by the controller in the battery itself - much like in laptops, and much like everyone here was surprised that the Tesla battery does not have.

So, to be clear, my understanding of this post, with full clarity, is: "A full discharge is disastrous. However, the situations reported were not full discharges. The controller in the battery shut them off before full discharge. The reported situations did require being towed, but once towed, it was trivial to recharge the batteries."
You're right. Search via URL is also on my to-do list.
Not likely, but they can very easily have a database holding all users with id starting with 'a'
This is a perfect example of the type of application where demoing before purchase is essential. I feel like I just lit $10 on fire. Additionally, I am more inclined to provide negative feedback via the MAS rather than sending the developer a helpful list of comments.

Hopefully the developer reads this thread and can comment on the possibility of publishing a demo outside the app store. A 7 day trial is trivial to implement.

So, let me see if I have this right.

The tax department approached telecom providers to intercept a bunch of calls with high-profile people (Radia tapes) conducting money laundering, tax evasion, buying media influence, etc. These were leaked (presumably by the telecom providers). This was so high-profile that there was a near-total media blackout about it.

Embarrassed, the government has created a central system for tapping phones, taking telecom providers out of the loop. Now they can tap a phone without the telecom provider knowing about it.

The government is making it easier to tap phones without anyone knowing: that's bad.

The government is ensuring that, when they do tap a phone, it isn't leaked: that's good.

The government is only doing this because there is so much corruption that it's embarrassing when these are leaked: that's hilarious.

This is actually very similar to a method of doing tessellated origami with a grid of folds. [1] I wish I could find a picture of it, but I've got an origami tessellation I folded that has this same 1 degree of freedom that allows it to be folded and unfolded by pushing and pulling. Only difference, is that instead of going flat, it turns into a spiral when you compress it. Very similar to [2]. This all being based on the work of Taketoshi Nojima.

Another good add-on to consider is RequestPolicy. It controls cross-site requests and thus blocks a lot of stuff before it even loads. It's a nice complement to NoScript.

If you don't like all of the social media buttons (which are also trackers and are, in my opinion, an eyesore), consider subscribing to the Antisocial filter list[2] for ABP. It blocks all of these pesky, useless annoyances and removes them from sight.

Oh, and btw: Chrome is Chromium based, not the other way round. ;)

You can switch blocking off, and that is, for some reason I don't understand, the default. Ghostery runs a simple wizard the first time you restart the browser after installing it where it asks you if you want to turn on blocking or not.

Simple reliable replication

I cringe every time I read that. MySQL replication is many things, but it is not reliable (as anyone who has used it at scale will confirm).

I think the only reason this myth prevails is because hardly anyone ever actually verifies if their master/slave are in sync. A table checksum can be a real eye-opener here, especially on a deployment that's been running for while and undergone schema changes, restarts, network splits, etc.
I'd definitely take the numbers, but I'll pass on the interview. A few soundbites from a college student who fits the mold imagined by the author is the only thing I can think of that would be less useful than the fluff and conjecture filling the rest of the article.
<rant>Simple, but not reliable. I've seen admins enable statement-based replication without understanding it, and trash the db. Which is generally my gripe with MySQL: it has some popular features that only work if you don't look at them too closely; starting with support for the SQL standard.</rant>

PostgreSQL's built-in replication is pretty easy to set up[1] and provides a writable master, and a cascade of slaves. Slaves can be synchronous or asynchronous, and the synchronicity can be turned off per transaction.

Air Force Drops Plans for iPad Flight Bags Over Security Concerns

Let's assume the following technologies would all make sense in something like this:

- Eye tracking.
- Object recognition (similar to Google Goggles)

So Google can tell what you're looking at, and for how long. Nope. Can't see any possible risks there from the company which tracks you across the web...
Then why didn't this Tesla representative say so? Why didn't he say, "We have followed up with the source(s) of this story and been unable to find any instance of a need to replace all the battery cells in a so-called 'bricked' Tesla. All instances only required a charge and reboot with service costs never exceeding $2k." ... or something like that?

I like the trashing of a bad rumor against technology as much as the next geek, but this Tesla response was spin and speculation thrown against more substantial-sounding reports of a problem. It was weak and since the strong alternatives are easily imaginable, it was likely weak for a reason -- ie, the reports of $40k bills were relatively accurate.
This is an exceptionally lame rebuttal.

> There is a fundamental problem when any rechargeable battery is discharged and then left to sit for months. Any boat owner understands that that's why you plug in a trickle charger when the craft is put into storage.

Yes, it's an excellent strategy to assume that your car buyers will also be boat owners, and therefore know all the things that boat owners know without you needing to explain them. Because who doesn't own a boat, right?
Switching keyboard layouts and language settings under Windows and on other Desktop OSs I find something of a minefield.

It should be easy to just jump on somebody elses machine and change language and keyboard settings mid session, and at session start up.

I would ideally like to have a global system setting, which could be overridden on a user session or on a per app basis.

The shortcut to the control panel ideally will be painfully obvious - just a click away. So that if I sat down in front of another PC that currently was set for Arabic and Colemak (let's say it's possible hypothetically...), I could quickly take control and switch to my personal preferences. Could pair programming work?

I especially dislike the way this is currently done under Windows, so welcome change.

The according method which most maps use is designed so you can open a reasonably arbitrary section of map at the same time which is important when you want to do things like compare routes which cover 4 folds at the same time. All the while being able to quickly flip it over and see what's on the other side.
