In a diesel engine, only fresh air is in the cylinder during the compression cycle. At the top of the compression cycle, that's when the fuel starts to be injected and immediately burns/explodes. There's other reasons why petrol in a modern diesel engine wouldn't work, but i don't think pre-ignition/detonation is one of them.

"Throttle" in a diesel actually controls for how long the injection takes place.
Sorry for being pedantic, but the theme is called "Darcula".
PostgreSQL has been speculated to get "it'll be all better RSN" failover for as long as I've been using it (around 8.4 IIRC). ;-)

But yeah, what made FoundationDB's SQL-Layer exciting (for me) was:

- For small clusters it was free.
- Automatic HA
- Operationally Inexpensive (talking admin time/effort/training; far cheaper than PostgreSQL)
- Horizontal Scalability

The things that didn't matter for the 99%:

- It wasn't very fast.

I don't have "big data" problems (I could invent some). Most small shops (I suspect) don't.

The problem I do have is 3AM pagers, availability, wearing too many hats, putting dozens of hours into learning and experimentation to get PostgreSQL to use the hardware it's put on effectively, coming up with complex CARP+REPLICATION+FAILOVER plans, ZFS snapshotting because PostgreSQL still can't match the backup/restore process any commercial database had nailed down two decades ago, backing up the snapshots, figuring out how to partition clients into different table-spaces, blah blah blah.

You sacrifice some single-client performance with FoundationDB, but you solve almost every other problem you've got. And you now have the option of deploying a couple extra nodes to exceed your previously fairly intractable TPS milestones.

It's so easy in fact, you can now autoscale your database with your application servers.

And for your 80% of smaller clients it's absolutely free.

Such a bummer. :-(

I live fairly far North (above 60deg.) so getting outside while the sun is up during the winter is hugely important.

I take a walk at lunch every day, even when it's -40. Getting sun on your face changes everything.
I'm sorry you don't like C. I find it to be a great language for the kinds of things it's good at. I always have a lot of fun when I program using C. No, it's not the most productive language to use, but in some cases you'll be hard pressed to find an alternative; think memory constrained embedded systems, or even VM's, where you are not allowed to use malloc.
>Federal safety officials expect to finalize rules later this year requiring all hybrid and electric cars to play fake engine sounds to alert passersby, a change that experts estimate could prevent thousands of pedestrian and cyclist injuries.

Yeah, because those pedestrian and cyclists should be responsible for staying out of the way of badly driven cars... Just think how safe things would be if we cranked things up so loud that drivers could hear other cars.

Will your child be 1 in 100?
Approximately 1 out of 100 children are born with some sort of Congenital Heart Defect. When my daughter had open heart surgery at 6 months old, I began to wonder how we might explain the scar to her, and how she would explain it to others. I ended up writing a poem that turned into a book. www.ziplinebook.com

I share this with HN for 2 reasons:

1. Awareness -Nearly twice as many children die from Congenital Heart Defects in the United States each year as from all forms of childhood cancers combined, yet funding for pediatric cancer research is five times higher than funding for CHDs.
Learn more @ http://www.chop.edu/centers-programs/cardiac-center/heart-disease-awareness

2. Provide an example of how sometimes a personal passion becomes a successful product. My only thought when creating it was my daughter - but now 1000's of kids have used it to understand why they have a scar. And feedback from parents has been very rewarding - please read some on the website. It was a fun project and I learned a lot about POD publishing.

Determining a user’s most important contacts on iOS
http://dbader.org/blog/most-important-contacts-ios
This article explains an App Store-legal heuristic that guesses the most important contacts in a user’s address book on iOS. Additionally, it provides an example implementation and a demo application under the MIT license.

Many iOS apps provide an “invite your friends” feature. From a usability design perspective it is desirable that the app suggests friends that are likely to be invited by the user.
The Stories Artifacts Tell
http://www.artifactsteach.com/pricing/
Artifacts as teaching aids spark discovery-based learning. A single object has many stories to tell depending on the questions asked. Educational websites provide social, cultural, or environmental contexts that allow for deeper examination of the artifact. Context enables students to use investigative skills to draw conclusions. Journalistic questions of who, what, when, where, and how become teaching aids that guide inquiry. Through the interpretation of their findings, students begin to see artifacts’ stories unfold. Different questions yield different interpretations of the research gleaned from educational websites about an artifact. These differences form the basis for meaningful student discourse and collaboration.

Anyone Know a Good SMS Payment Gateway?
The ideal process is the user would put his phone number into the web app, he would receive a text message, "text back <some PIN> to pay $X," and then payment would send a message to the web app server, maybe GETing something like Y.com/payment?from=5555555&secret_key=ZZZZZZZ

I'd like to get recommendations on who to use, and it's be great to know if anyone has used SMS payments in their own projects, and how it worked out.

How To install & Boot Linux Ubuntu 11.04 on a Windows 7 PC
http://readitsolutions.com/how-to-install-boot-linux-ubuntu-11-04-on-a-windows-7-pc
Ubuntu 11.04, or "Natty Narwhal," has been out just a few days, but already it's being billed as possibly the most accessible and user-friendly Linux distribution ever. With its new Unity interface, the open-source operating system mimics what many people are used to in the mobile arena to create a simple, intuitive way to get things done.

This may feel to you as if the procedure is long and difficult but that's not so. Follow the below steps as mentioned and you will end up having a dual boot of Windows 7 and Linux Ubuntu 11.04.

Install Linux Ubuntu 11.04 in Windows 7

1. Bootup from the Linux Ubuntu 11.04 live CD
In the Welcome window, select the correct language and click Forword.

Read the Preparing to install Ubuntu window.Check Install Third Party Software And uncheck install updates.Although Its not recommended to uncheck it but is speeds up the install process. and click Forward

2. In Allocate drive space, select Something else (that's IMPORTANT), and click Forward.

3. In the new Allocate drive space, do not click ‘Install Now' until instructed.
This section has been designed by the Ubuntu team with dual-booters in mind. Thanks team!

Highlight the free space you created earlier on the correct hard disk (sda=1st disk, disk0)
and click the Add button. Note: the vertical scroll bar appears only when you mouse-over it.

The first partition will be for /boot. When setting up an LVM-based system using an Alternate Installer ISO image,

* The Create partition window will open.
* In Type for the, select Logical.
* In New partition size, the default disk space allocated to /boot is 258 MB
* In Location for the, select Beginning.
* In Use as:, select Ext2 file system.
* In Mount point:, select /boot in the drop-down.
* Click OK.

Back in Allocate drive space, highlight the now smaller free space (scroll down if necessary)
and again click Add.

* The Create partition window will open.
* In Type for the, select Primary (but Logical if 3 Primaries already exist on that disk)
* if in any doubt, select Logical.
* In New partition size, enter all available minus about 2000 MB for the Swap.
* In Location for the, select Beginning.
* In Use as:, select Ext4 journaling system (the default) in the drop-down.
* In Mount point:, select / (forward slash) in the drop-down.
* Click OK.

The Not-All-That-Important Higgs Bosun Particle
http://www.davidglarson.com/science/the-not-all-that-important-higgs-bosun-particle/
The Higgs-Boson “God Particle” is like a step in a marathon. To win a marathon, each step is important, but the crowd isn’t going to be shouting “look at that amazing step!” for just one step. Yes, to a large degree, proving the existence of the Higgs “completes” the standard model. So the excitement is for the “completeness” of a badly incomplete model.

Also, it’s more clear that some kind of bosun has been discovered than it is that this is the Higgs. Considering that the standard model understands so little about the universe we actually live in, there’s a not insignificant chance that there’s something more to learn about this bosun/from this bosun beyond it being simply a perfect fit for the Higgs slot in the standard model.

Although bittersweet, the lessons learned are priceless.
