Last Minute gift options: all things digital.

Maybe this is obvious - but since I am always very late in buying christmas presents, here are some options for you people out there that have (like me) not all gifts together yet:

#1: Give awesome games and help charity: The Humble Indie Bundle #4 includes these Games (even with Steam coupons to import the games to your Steam account): Super Meat Boy, Shank, Jamestown, Bit.Trip Runner, NightSky, Cave Story+, Gratuitous Space Battles,
Crayon Physics Deluxe, Cogs, VVVVVV, Hammerfight, And Yet It Moves.

#2: Give some digital stuff, such as Kindle eBooks, or Steam Gifts to gamers.
You would need to know for sure, if the person already got that present, though. There's nothing worse than getting digital content twice.

#3: Order something online and print out the picture of it.
I know, this is cheesy, but after all you can all blame it to the parcel service: "The shipping time was more than a month!". Make sure, if your item is from ebay, that the real purchase date can not be found out.

To all Nanofunk readers: merry christmas! Hope you have nice and relaxing days.

OCZ Vertex 3 Fail: “Runtime corruption detected on SSD” and why SSD drives are not safe yet.

After almost 9 months with the OCZ Vertex 3 SATA-6GBPs (read about my OptiBay two-drive setup) and mostly no issues, the drive died on me. Starting with several GSOD (Grey Screens of Death) on my OSX Lion MacBook Pro, the drive became more and more unreliable.

Nov 28 18:30:43 mbp kernel[0]: hfs_swap_BTNode: record #55 invalid offset (0x9B46)

It was getting slower and slower, reporting tons of errors in the Console.app. Then, it did not reboot anymore. Even in an external USB drive enclosure the drive did not mount anymore. Contacting OCZ about this issue, they sent me an RMA number right away and told me they will replace the drive. Does this mean our data is not safe in SSD? What can we learn from this?

First of all, it is a myth that SSDs are more reliable than hard drives. Secondly, they are not even fully supported on OSX yet (see Should I use Trim Enabler on Lion for the OCZ Vertex 3? No!) - at least if you install the drives yourself (which is also what I would suggest, since Apple does not offer any decent SATA 6GBPs drives yet).

So where is the proof, you ask?

Proof #1: The Hot/Crazy Solid State Drive Scale (via Coding Horror)

Super Talent 32 GB SSD, failed after 137 days
OCZ Vertex 1 250 GB SSD, failed after 512 days
G.Skill 64 GB SSD, failed after 251 days
G.Skill 64 GB SSD, failed after 276 days
Crucial 64 GB SSD, failed after 350 days
OCZ Agility 60 GB SSD, failed after 72 days
Intel X25-M 80 GB SSD, failed after 15 days
Intel X25-M 80 GB SSD, failed after 206 days

As a commenter put it: "Average life of SSD = 227.375 days (based on Wills' data)" - which is also what I can confirm.

SOLUTION: Backup early, backup often. Don't rely on the SSD and make two local backups plus one backup in the cloud.

Proof #2: long-term study of SSD failure rates (via Tomshardware)

SSD vs HDD Failure Chart

SOLUTION: Buy drives that come with a very long warranty. Be prepared to let your drive replace for several times.

I am still waiting for my replacement OCZ Vertex and I will benchmark how fast it will die again. Since OCZ told me, it can take up to three weeks for my replacement to arrive, I bought myself a Seagate ST750LX003 750 GB SATA 600, Momentus XT, 8 GB SLC - it's a hybrid 750GB HDD with an 8GB SLC cache. The drive shifts data that is used often in the 8GB SLC SSD space automatically. While the SSD part of this hybrid drive can also fail, the data won't be lost and it will suffer just some minor speed loss (if it fails, since SLC is said to be more reliable than MLC chips). While this disk is now my main startup disk, i will go back to using the OCZ Vertex 3 again, once the replacement arrives. I just need to backup regularly - the speed gain is really worth the trouble.

iPhone 4S / Canon 5d MKII Side by Side Comparison

***You can download the full 1080p version of this video for a more accurate presentation.

Here's a "fair" test between the iPhone 4S and the Canon 5D MK II. I made a little rig that allowed me to shoot both cameras at the same time side by side. All scenes are perfectly synced together so you can pause and scrutinize the frames! See photo of the makeshift rig in the photo area.

Exposure, shutter speed, frame rate and picture style were matched as close as possible between the two cameras. (I used the Zacuto Z-finder to help me adjust exposure for both iPhone and 5D)

This test shows that the tiny F2.4 lens and sensor on the iPhone are pretty nice. It even got a little depth of field!

I did not overlay the exact ISO and Stops 5D settings per shot. It was too much to keep track for this simple test. To be fair I matched 5D exposure to the iPhone so no "Cinestyle" / 24p here.

Here are the settings:

iPhone 4S

- AE.AF locked. That's all you have!

Canon 5D MKII

- Canon 50mm 1.4
- ISO 160 ~ 640 (varied per shot to match the iPhone)
- F 7~22 (varied per shot to match the iPhone)
- Shutter 1/60th
- Auto WB
- Standard Picture Style
- 1080p 30

Should I use Trim Enabler on Lion for the OCZ Vertex (3)? No! (Benchmarks inside)

We recently blogged, after purchasing two OCZ Vertex SATA3 Drives (240GB) and inserting them with an Optibay setting (2 Drives in one MacBook Pro; see our previous post: 2011 Macbook Pro and SATA III 6Gbps, Optibay: two HD drives – setup explained).

We also blogged that enabling TRIM is a good thing, although it seems that it seems to be not necessary on Sandforce based chipsets.

Since we still were experiencing freezes and Sandballs on our Mac OSX Lion 10.7 SSD Setup that were actually not related to TRIM, also the system did not feel as snappy anymore.

Conclusion: don't use TRIM on OSX Lion 10.7, if you are using a Sandforce based SSD. Revert to the original driver and not only the Beachballs will go away, but also the system feels snappy again. See the below Benchmarks for real-life results (since AJA System Test does not work on internal drives, we can recommend using XBENCH to verify the figures for you).

Mac OSX Lion 10.7 System Freezes: kernel: IOSurface: buffer allocation size is zero (console message)

Some people experience system freezes on Mac OS X 10.7 Lion, but also on Snow Leopard: kernel: IOSurface: buffer allocation size is zero.
The Error is visible with Console.app ("All Messages" respectively "kernel.log")

To reproduce the issue:
1) click on "Clear Display" in Console.app
2) go to http://www.adobe.com/software/flash/about/ and the error will show up in the console.

The error must be Flash related. Sometimes, the whole System is unresponsive, freezing everything but the mouse. There is no official response from Adobe or from Apple, so we can only hope and wait. Please check your Console.app for this error and respond to any of the existing discussions.

Screen Shot 2011 07 28 at 11 52 25

[Update] the error message also seems to have surfaced in 10.6.4 already, as visible in the Apple Discussion Forums

[Update] installing the Adobe Flash Player 11.0 from Adobe Labs seems to at least minimize the freezes, but still the console messages appear.

[Update] i posted a poll on insanelymac to see which browsers and systems are affected. please also post your results there!

[Update] the new Beta 2 11.0.d1.98 of the flash player is out (thanks JP Hansen)

[Update] The Flash Player 11 is officially released. It seems though, that not all issues are resolved with Mac OSX Lion compatibility.

[Update 23.12.2011] more than 6 months after the issue was reported, (and we have Apple Mac OS X 10.7.2 and 10.7.3 in beta) there is still no update on this issue from Adobe. Please write your concerns to the Adobe Forums in the existing thread to have them fix the issues! Especially for SSD owners this is unacceptable!

Existing Discussions:

* Nanofunk.net discussion thread in the Adobe Flash Player Forums
* Thread in the Apple Support Communities Forum
* Thread on MacRumors Forums regarding Lion Freezes with kernel: IOSurface

[Update] I posted to the Adobe Bugbase with a bug description. Hope they will respond now.

SPEED SHOW vol.2: who the fuck do you think you are talking to? Thursday, 8th of July 2010, 19:00 – 22:00 h, Vienna, Austria

 

 

 

SPEED SHOW vol.2: who the fuck do you think you are talking to?

 

via fffff.at: "The 2nd edition of the SPEED SHOW presents again a wide selection of pop.net.art pieces and addresses various developments of performance related but still screen based art works. Most interaction and communication on the web bears it’s very own performance character. One could say Facebook is a huge mass performance piece. net.art in it’s classic form could be considered a performance by interactivity as well. In recent years artists from different fields work increasingly in a mix of performances and digital interventions. In some cases the screen itself, the beholder of the pixel is subject to fluctuations. In other works the performance is acted out by a hysterical mass or just by the code."
