arantius··on How Not to Sell Bitcoin on eBay for 300% Profit
The words you're using make it sound very much like you know what you're talking about. And it sounds interesting. But I can only make sense of bits of it. Do you have a good suggestion where I can read a bit more about this?

I.E. Why is the space vs. space-time distinction important? Why is borrowing BTC important? You give an "i.e." but I still don't understand delta hedged.

arantius··on Firefox OS devices officially released
This release prodded me to look into Firefox OS again. I have a Nexus S lying around unused, and that's one of the supported "tier two" devices. So I installed it.

I really want to love it. I love Firefox, but Firefox OS is very much "not there" based on my experience. The browser is significantly worse than Firefox for Android. As far as I can tell, Sync is not available at all. Tapping the URL bar just/always puts your cursor where you tapped (does not select the text for easy replacement). Lots of smaller fit/polish things seemed much worse.

And the device experience is really strange. There's the "marketplace" but also the .. I don't know what it's called, two swipes to the left of the app launcher screen. The experience is very poor compared to Android/iOS; using familiar "apps" is really the mobile site for that service, and doesn't work as well as the Android apps I'm used to. (I.E.: Rating a movive in IMDB takes one tap to load another page, one tap to open the select box, another to pick the value, then another to submit that form. Versus one tap on Android.)

Lots of the "real apps" from the marketplace are also immediately greyed out if you lose data. Including simple games that totally should work offline. (Though I was recently surprised by how many games refused to run without an internet connection on my Android tablet recently, also.)

Sorry but ..

"$0.02 cents"? Do you mean "$0.02", or "2 cents" or two hundredths of one cent, or something else?

arantius··on Git tips to stop you getting fired
I use the git CLI for most work; "git gui" for reviewing changes between writing them and committing them, especially for committing partial changes. Almost nothing else.

In this case, I feel that it is not. It's just using the right data set for the job. This is exactly the sort of thing that sets are for.

arantius··on FROST: Forensic Recovery Of Scrambled Telephones
Don't miss the critical detail:

> 15) Flash the frost.img file from our download section to the phone: 'fastboot flash recovery frost.img'. For this command to work, the bootloader must be unlocked.

You must leave your phone in a vulnerable state for this attack to be practical. Otherwise it's a known attack vector.

arantius··on Adobe CS2 + Serials Free
I saw this the other day and it was down. Now it's back up. Is this "legitimate"? The story ( http://www.diyphotography.net/download-adobe-cs2-for-free as best I can tell ) isn't clear.
arantius··on How and why I run my own DNS servers
> This will only work if tinydns supports zone transfers (AXFR/IXFR), which as far as I can tell, it doesn't.

http://cr.yp.to/djbdns/axfrdns.html

It does. I'm doing this currently, I host primary DNS myself with tinydns, and the makefile sends a notify to the registrar-hosted slave DNS, which gets data via this daemon (with tcp server configured to only allow that IP).

arantius··on Rethinking Sleep
> What percentage of employee-days at Google actually involve a nap? 1%? 0.01%? Is it any higher than the traditional comic practice of "curl up under your desk"?

Complete anecdata but: I've seen people curled up on couches in the middle of the day plenty of times. I think the point is that, at Google, you won't be frowned upon for this. (Whereas it may be much more likely at other companies.) Not that you're mandated to nap after lunch or anything.

If you accept that a virtual keyboard is direct manipulation, can you accept that swiping the virtual keyboard is analogous to pressing the arrow keys on a physical keyboard? Then it's all the same stuff. Illusion barely broken, if at all.

arantius··on Are Expensive Batteries Worth the Extra Cost?
I've occasionally discharged my NiMH batteries low enough that my LaCrosse charger decides it's a dead cell. But shorting the positive terminal with a working battery in the charger (for just a moment), or putting it in a simpler trickle charger for a while (minutes? I usually forget and leave them for hours), always works.
arantius··on Are Expensive Batteries Worth the Extra Cost?
In late 2010 I bought "24 Centura AA LSD NiMH Rechargeable Batteries" from eBay (for $33, so just under $1.66 each) -- specifically the long-life kind, that was around when I heard of their existence.

I've used them in remote controls that sat for months and continued to work fine, and in wii-motes for similar periods. I haven't measured the life/performance much more carefully than that. Except I do have a nice LaCrosse charger that measures things and claims to be putting in an average of 2Ah, which compares favorably to the (2300 or 2600 mAh if memory serves) usually inflated rating that they claim.

The trick, though, is that with rechargeables (and especially long-life like these), you keep a small but sufficient stock of charged batteries ready. When something goes dead, the dead batteries go in the charger, and the stock (immediately) goes in the thing. By the time the next thing dies, the previous set is charged and ready.

Not flash "cookies". You only have one flash plugin that runs in every browser, and has one "cookie" store.

(Not that I know if/whether FB abuses this, I don't even have an FB account. Just sayin'.)

> Negatory. We need to improve our UI metaphors. In the case of finding something, holding down one key while pressing another has no parallel to real life searching.

I rather strongly disagree. You're essentially saying: we should limiting the capabilities of tools (regardless of whether they are electronic or not) to things that already have a direct and obvious parallel to previously existing things that are wholly obvious.

That essentially means: we should stop all progress. Absolutely not. Human beings are tool users, and tool _makers_. We make new tools to serve new problems. We learn how to use them. Via this mechanism, we advance.

arantius··on FCC releases report on America's broadband providers
> Downtime in NYC from TWC is painful

Really? I run nagios at home, and right now it says year-to-date I've had 28m 40s of downtime, for 99.988% uptime of my cable internet service (for the host monitoring my first-hop router). This is in Chelsea, Manhattan, with their "wideband" level of service.

arantius··on Find is a beautiful tool
Because it's a good/easy way to insert the file name into the _middle_ of the statement. For example:

  find . -name "*.gif" -exec convert "{}" "{}.png" \;
Will convert every GIF in the current directory (and its descendants) into a PNG, assuming imagemagick's convert is on your path. Is there a better way? Not that I know of.
arantius··on GoDaddy SSL Cert Scam
I've used http://www.1and1.com/ for registration ($10/yr normal prices) for some time. The UI is awful, but aren't they all, and I basically never need to use it once it's set up, so it's OK by me.

The commonly named alternatives seem (all for .com): Namecheap $10 Name.com $10 Moniker ??? DNSimple $14 Gandi 12,00 € (~ $17) Joker.com $12.80

Name registration is a commodity. I go with the cheapest provider.

> The moment that you store that URL in other service, a number of those tags become incorrect anyway (it is not an email anymore), and the stats you will get from it will be tainted.

It sounds like you're probably misunderstanding the actual use case involved.

If you're a business, paying for traffic, you want to know ROI. If you spend X dollars and get Y visitors which make you Z dollars, you want Z > X, and you want to know what the relationship between the three values are, to know if spending more would be worthwhile. You don't actually care if the human being who clicked the link was currently in their email, rss, or anything else. You wan to know "spending dollars this way resulted in this profit". You want to identify the source, in your dollars, of your income.

I enjoy my Buffalo WZR-HP-G300NH . I had a WRT54G as well, but then I got an internet connection faster than it could handle (it became the bottleneck). Comes stock with (a modified version of) DD-WRT (and flashing your own is supported).
