Apple's 2014 WWDC Keynote Will Be Streamed Live; Hopes For a Microconsole?

Bram Stolk Article seems ignorant of current state (147 comments)

I think the article screwed up here.
From the article:

"Party Play allows four friends to connect via BlueTooth controllers to an iPad, enabling local splitscreen multiplayer. Take your iPad out to your flatscreen TV with a HDMI adaptor and bingo, the Apple microconsole has arrived."

So the iPad is the microconsole, and you can ALREADY DO THIS.

The iPad can mirror anything to a TV using HDMI, and the iPad can already do MFi controllers, so there is NOTHING NEW HERE.

Joss Whedon Releases New Film On Demand

Bram Stolk Rent vs own (137 comments)

I do not like renting, I prefer to own.
Just put it up on AppleTV so it conveniently becomes part of my iTunes lib.
Also I don't have patience for sloppy flash based players.

Heartbleed Coder: Bug In OpenSSL Was an Honest Mistake

Bram Stolk Re:Bigger problem: stupid 'optimizations' (447 comments)

I bet it is.
Where are the numbers from the profile runs?
Could have left it in the code comments, or somewhere on a mailing list.

Heartbleed Coder: Bug In OpenSSL Was an Honest Mistake

Bram Stolk Re:Bigger problem: stupid 'optimizations' (447 comments)

OpenSSL has a functionality: to provide high security. If it fails to do that, it loses all reason to exist, regardless of how efficient the code is.
Also: allocation does not tend to show up in profiling.
Last, note that allocation was deemed slow on SOME PLATFORMS.
Way to go: completely compromise the security on all platforms because you think that on some platforms allocation is slow.

PC Game Prices — Valve Starts the Race To Zero

Bram Stolk Re: It's not free (212 comments)

Hrs of development does not scale linearly with hrs of play.

A game with double the content will typically take marginaly more dev time to create.

Bugatti 100P Rebuilt: The Plane That Could've Turned the Battle of Britain

Bram Stolk counter rotating (353 comments)

If the two engines rev at different speeds, the whole plane will start to roll, faster and faster.
Consider this scenario:
Engine 1 stalls.
Engine 2 has its throttle stuck at wide open (Aircraft engines do this e.g. when linkage breaks: full throttle is safer than no throttle.)
Then the pilot will die a horrible death EVEN BEFORE HITTING THE GOUND.

You can do this with electric engines, not with IC engines.
It's a death trap, and it will not fly.

Ask Slashdot: Do You Still Trust Bitcoin?

Bram Stolk Logarithms! (631 comments)

Guess what... bitcoin price is arguably still trending up.
All you have to do is look at the logarithmic graph.
And frankly, logarithmic is the only way to view it, considering the exponential price movement.
Here's the data: http://bitcoincharts.com/chart...

NVIDIA Tegra Note 7 Tested, Fastest Android 4.3 Slate Under $200

Bram Stolk benchmark (107 comments)

It does well for on-screen benchmarks, because of the low resolution of 1280x720.
For on-screen tests, it will have to process fewer pixels than the more expensive models with high-res screens.
This makes it look faster than it is, as you can see by the off-screen benchmark results.

Kernel DBus Now Boots With Systemd On Fedora

Bram Stolk Re:Listen to A.S.T. (341 comments)

That word does not mean what you think it means. In fact, kernel dbus is probably the most microkernel-ish feature I've seen added to the Linux kernel (although I haven't been paying close attention).

From wikipedia:
Traditional operating system functions, such as device drivers, protocol stacks and file systems, are removed from the microkernel to run in user space.

Kernel DBus Now Boots With Systemd On Fedora

Bram Stolk Listen to A.S.T. (341 comments)

Andrew S. Tanenbaum had a point about Linux not being micro kernel.
This is getting crazy: moving perfectly fine userland systems to the kernel.
Isn't the kernel large enough already?

60% of Americans Unaware of Looming Incandescent Bulb Phase Out

Bram Stolk Sometimes you need inefficiency (944 comments)

My previous apartment had a bathroom without conventional heating.
You could still make the bathroom warm enough with the lights above the mirror though.
Six bulbs of 60W gave me a nice and cosy 360W heating, which is actually not that bad in a small bathroom.
If you remember to turn on lights an hour before your shower (in the winter), you would be fine.

My new place has heated floors in the bathroom, so I no longer care.
But for some people, 60W bulbs are nice.

Bitcoin Thefts Surge, DDoS Hackers Take Millions

Bram Stolk Re:A limited number of Bitcoins (305 comments)

The effect of selling is less than you think.
mtgox is not the biggest exchange, but it can easily do a $1M exchange without affecting price in a too dramatic way.

The nice thing is that their bid book is open for every one to see, so you can predict what happens to price at large orders.
See: http://mtgoxlive.com/orders
At the time of writing, a $1M sell or buy would move the mtgox exchange price 5% in either direction.

If you sell in the largest exchange in the world, which I understand is in China, it would move the market less than this.

Bitcoin Tops $1,000 For the First Time

Bram Stolk Re: Sell now. (371 comments)

If 10 people with 1000 bitcoins each now went to MtGoX and wanted to cash in their bitcoins, what would that do to MtGoX? I think they'd be fucked.

Seriously, this is empty speculation and there isn't the actual money invested in bitcoins to support this increase in face value. The system is fucked. Theres no way the bitcoins in circulation today could actually be cashed in for actual money.

Due to the open nature of the bid book at MtGox, you can see EXACTLY what happens at a sell of 10k btc.
http://mtgoxlive.com/orders

At the time of writing, it would drive down the price to $800,- roughly.

Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations

Bram Stolk Re:Is my reasoning sound? (285 comments)

My line of reasoning is such: credit is necessary for the functioning of the modern world. A world dominated by Bitcoin will still have credit. Credit without regulation would be disastrous. Banks cannot be expected to self-regulate properly. A regulatory agency would be in charge. This regulatory agency would then have control over the amount of money in existence. And then we are right back to square one, in terms of the government's involvement in money.

Good point.
There does seem to be some catch22 here.

Still: how did the economy of the 19th century work though?
Bank notes were still linked to gold that was in the bank's vault.
They seemed to make it work.
As a matter of fact: US economy did extremely well in 1800s, where pretty much every year, there was deflation instead of inflation.
Most years, you would get more for your dollar than previous year.
Translate that to the hypothetical 2030 economy where the gold is replaced with bitcoins, would it not be able to function?

Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations

Bram Stolk Re:Is my reasoning sound? (285 comments)

... If you still think you're right and everyone else is wrong, then buy Bitcoins.

I'm glad I did.
My $300 coin is now worth $660, in just 11 days.
Tulip mania? Perhaps. But just maybe, with a chance ever so slight, it is something that's here to stay.
If it does, I'm insured against it, and will not have to buy my bitcoin for a million dollars.

Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations

Bram Stolk Re:Is my reasoning sound? (285 comments)

The 21M bitcoins are just the "base" money supply. I assume in this future world order we are not prohibiting the formation of banks or the ability to get credit. Once credit becomes available, and the issuing notes become "almost as good as" the bitcoins that back them, then the total amount of "money" in circulation may be much, much more than the 21M bitcoins and will probably mirror growth in the real economy.

Inasmuch as credit is desireable and banks serve a purpose (and even a "central bank" may serve a purpose), you might see all of these institutions rise up naturally around this new currency, and the fixed 21M won't matter much at all.

You make a good point, which I had not considered.
Still, the 21M limit will still matter I think.
It *used* to be that banks had a strict minimum reserve for deposits.
Even with the 'money multiplier effect' the bitcoin will be a scarce resource for the banks, assuming that governments will still dictate a minimum deposit reserve. It's unlikely the minimum reserve will be scrapped altogether, as it would make banks too vulnerable.

Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations

Bram Stolk Re:Is my reasoning sound? (285 comments)

The value of owning 1/21M of the entire money supply depends entirely on the price level of the goods and services you can buy with that money.

Right now, someone might trade you an iPad for 1 bitcoin. Maybe in 2030 that bitcoin gets you a gallon of milk.

That does not make sense: it would mean that the worlds money supply in 2030 would be enough for just 21M gallons of milk and nothing more.
Bitcoins are set up for hyperdeflation, not inflation.

Wikipedia calls this 'its deflationary bias'. (http://en.wikipedia.org/wiki/Bitcoin#Economics)

The geography factor in freemium conversions

Bram Stolk (24781) writes "Infographic on the the geography factor in freemium conversions.

Or: why Kiwi customers rock.

Sales and download data from Apple's app store can be valuable source to distill insight from. In this example: in which countries are customers more likely to transition from free to paying users?"
