jpablo··on Exploring different microcontrollers less than $1
Recently I was looking for a project that required a network of microcontroler and was looking for the cheapest mcu in around quantity 50. My requirements where pretty modest, I just needed 2 GPIO and 1 PWM ouput.

I ended up ordering the Attiny13A as that was the cheapest option in aliexpress/ebay with freeshipping in small quantities (around USD $0.3 a piece).

I would have loved to find something even cheaper!

jpablo··on The most accurate map for August 21’s total solar eclipse
Have you ever seen a total eclipse? An anular/partial one doesn't even compare to watching the sun during totality with your bare eyes.
jpablo··on Raspberry Pi Zero W, with Wi-Fi and Bluetooth, priced at $10
Probably better to go with a ESP32.
jpablo··on Franka: A Robot Arm That’s Safe, Low Cost, and Can Replicate Itself
I'm guessing it could 3D print/CNC quite a few of its own parts?
jpablo··on Taking a month off from OSS volunteering
As I read it, he was offered money to fix it. But he said he didn't had the time.
jpablo··on Filmmakers Ask Nikon and Canon to Sell Encrypted Cameras
Not just image quality. But just very diferentes capabilities, like super telephoto lenses, ultra wide, instant focus, accurate focus tracking, easy manual exposure, external flash sync and the list goes on and on.
jpablo··on Alibaba Posts $1B in Sales in 5 Minutes on Singles’ Day
It has a huge timer in the front page stating that the deals starts in about 11 hours from now.
jpablo··on Distrusting New WoSign and StartCom Certificates
I don't like this at all. The only value left in WoSign root certificates is in issuing backdated certificates that wouldn't be widely distributed. So basically the only way to extract any money out of their current root keys is to sell rogue certificates for targeted attacks.
jpablo··on Remediation Plan for WoSign and StartCom
I dont like this route. The only value for the WoSign keys for a whole year would be issuing certificates with a doctored notBefore date, and they can't do that publically.
jpablo··on People from Mexico show stunning amount of genetic diversity
As a Mexican I find the comment section nitpicking every word of the article as racist very funny. Americans have really thin skin. Political correctness is indeed drowning the exchange of ideas!
jpablo··on Richard Stallman's 22-Page Rider (2011)
I'm guessing that was added the 1000th time he was asked about breakfast, this one last host being very pushy about it.
jpablo··on Let's Encrypt has issued its first million certificates
I don't think its fud. Calling apt-get is just crazy on my view.
jpablo··on What does a GB of Internet service really cost? The worst case scenario (2011)
Because if the enterprise service stops working you'll have someone working on it and giving status reports on progress in hours. In residential you'll have someone look at it in 2-3 days if you are lucky.
jpablo··on Show HN: Ponzi.es – Startup sticker ponzi scheme
It is, but for it to work you have to give the appearance that it is actually working for a long enough period of time. That requires exponential grow or most people reinvesting returns (so they don't realize there's no actual money to pay them back).

If you give the returns immediately (the two stickers) with no option to reinvest, the ponzi scheme is going to run out of steam very quickly and there's no way this is going to attract a lot of people.

In summary, this is a Ponzi Scheme, but not one that has a lot of chance of being sustained for very long.

jpablo··on RaspBSD – FreeBSD images for the Raspberry Pi
It's the same approach the official Linux Raspberry PI images follow that way you can support all raspberry pi versions with a single images.

There potentially could be an speed up by rebuilding everything for armv7 (specially for NEON-fp) but no one has done it yet.

jpablo··on Unbounded High Dynamic Range Photography Using a Modulo Camera
I know, I just don't see how it solves this issue. You couldn't solve the issue before "fumbling with aperture size and exposure length"

The only thing I would consider that solves "fumble with aperture size and exposure length" would be huge ISO range (both ways) without any noise.

> No more will photographers or even ordinary people have to fumble with aperture size and exposure length.

jpablo··on Unbounded High Dynamic Range Photography Using a Modulo Camera
That's just really a completely misguided statement. No mater how much you fumble with aperture and shutter speed there's simply no way to expand the camera sensor dynamic range without taking multiple exposures.

Besides I have never seen "ordinary people" fumble with aperture size and exposure length so that's a solved problem. Sometimes it gives "wrong" results, like exposing for the highlights rather than the shadows, that's what this technology solves.

jpablo··on Windows 10 IoT Core for Raspberry Pi 2
Seeing that they just added Wi-Fi and Bluetooth support I find ironic that Windows has the disadvantage on drivers and Linux has the upper hand.
jpablo··on Windows 10 IoT Core for Raspberry Pi 2
I'll disagree there. After spending hours trying to make sense of the Win32 API documentation in msdn. Often failing to make sense of it, finding the answer in Raymond Chen blog a long with a few lines pointing out that the msdn documentation doesn't cover some important cases/caveats.
jpablo··on In Fake Universes, Evidence for String Theory
If GR and QM can be derived from string theory, but the base theory doesn't provide any extra prediction of its own or simplifies the other two theories, then what good does it serve? Can we at that point say it's a "correct description of reality" or just a clever mathematical trick?
jpablo··on What Happens When You Install the Top Download.com Apps
Chrome?
jpablo··on You can't dig upwards
Right, since I have the exact opposite experience and I can find a logical explanation for it.

I learned to drive in an automatic transmission car. I was still in terror when first learning to drive that car. Later on I got a new car, and since manual transmissions where cheaper I got a manual one. I was again terrorized every time I had to stop and get into first gear again, or when I was stopped in a hill. I can only imagine the absolute nightmare I would have been trough if I had to learn both how to operate the stick shift AND the rest of the car and laws of the road at the same time. I actually think progressive learning was better for me.

Same with programming, I learned GW Basic as a kid doing games and what not. Then switched to Pascal, then C and then ASM. I can only imagine how motivating it would have been to 10year old me having to write pages and pages of ASM just to do the simplest thing. Instead learning a easy high level language helped me stay motivated and learn progressively getting into harder stuff little by little.

jpablo··on Why the Chess Computer Deep Blue Played Like a Human
He didn't walk out. He played all six games in the match and lost the match in the last game after he played a opening that was know as losing by everyone after a piece sacrifice (it was speculated that Kasparov was gambling that deep blue wouldn't make the sacrifice and then he will have the upper hand).

Deep blue played pretty much "like a machine" except for a few moves that where considered very human because they hold very long term advantages.

After the match Kasparov hinted that IBM must have cheated, of course now a days a machine running in a off the shell desktop machine will surely beat the current world champion in a match, so Kasparov was just being a sore loser at the time.

jpablo··on Adobe Acquires Photo-Editing Platform Aviary
Photoshop is for editing photos, not for drawing "assets". Unless you are trying to tell me that digital cameras will produce a vector drawing of scenes, I don't see bitmap editing software going away anytime soon, or ever.
jpablo··on S.&P. Says Argentina Has Defaulted
As I understand this funds didn't lent Argentina anything, they bought the bonds in the open market at a huge discount.
jpablo··on The evolution of chess: Game lengths and outcomes
Maybe they dropped adjourning games.
jpablo··on Microsoft rescues XP users with emergency browser fix
And I think Microsoft actually stopped selling Windows XP one year later, in October 2010.
jpablo··on Microsoft rescues XP users with emergency browser fix
If you need Internet Explorer updates for those you are using them wrong.
jpablo··on Facebook Buying WhatsApp for $16B in Cash and Stock Plus $3B in RSUs
WhassApp is the standard in Mexico. It replaced Windows Live (MSN) Messenger after they killed it by trying to make everybody switching to Skype and the interest of the people shifted to mobile.
jpablo··on TrueCrypt Volumes are Indistinguishable from Random Data
The question is, do people usually keep large areas of random data on their hard disks?
