Raspberry Pi’s Eben Upton: Open Source Lessons from Wayland

By libbyclark

Eben Upton Raspberry Pi

In less than two years the Raspberry Pi has sold more than 1 million units and become widely used and adored among DIY hackers and embedded professionals alike. It began in 2006 as a modest idea to provide a low-cost educational computer for students to tinker with. Now the $25 Linux-based single-board computer is the basis for all kinds of gadgets from near-space cameras, to open source spy boxes, to the PiGate, a full-scale Stargate replica.

During that time the board’s creators have also gotten a fast education on open source software development and the process of collaboration, said Raspberry Pi Foundation Executive Director Eben Upton. He’ll share some of those valuable lessons during his keynote talk at LinuxCon and CloudOpen North America in New Orleans, Sept. 16-18, where he’s also planning a new demonstration of the Pi’s prowess.

Here, Upton talks about some of the open source projects the Pi Foundation is involved in; their choice of the Wayland display manager; their focus on media performance; their efforts to expand computer science education and literacy; and his favorite Pi projects.

Can you give us a preview of your LinuxCon keynote?

I’m not a natural open source guy. No one would mistake me for being a classic open source fan. I find it interesting to the extent it’s useful to me. So I’ve come to RasperryPi as a bit of a novice, with not so much experience in running a project that’s deeply intertwined with the open source community. I’ve made a lot of mistakes so I’ll talk about what I’ve learned.

I thought we could ship a platform that basically works and the open source community will take care of the rest. There are some areas they’ll do a great job, particularly things that have a lot of eyes on a problem and are able to attract the attention of a particular expert. The other things aren’t so great, particularly around desktop acceleration. We’ve had to go out and pay contractors who are able to move that stuff forward for us. It’s been a learning process of finding what those categories are — the things for the community and those for the foundation.

How is the Pi Foundation involved in open source projects?

We’ve been supporting a number of open source projects. We make a little money every time we sell a Pi and have a little pot of money we spend on things deemed important to the mission of the foundation.

There are some bits of Linux infrastructure not well optimized for our platform so there’s been a low level of work paying people to write fast implementations of audio codings, for example.

Higher level stuff we’ve been doing are things like Wayland, accelerated web browsing. Things that are tying us into the way the desktop experience is evolving under Linux.

What are you working on right now?

We’re pushing on support for Wayland. It’s the future of Linux desktop graphics. It’s a clean-break architecture. It’s obviously somewhat controversial, there’s a feeling that there’s …read more

Power Supply for Mercury lamp

By anvoice

Hello,
I am trying to set up a custom exposure system for photolithography. One way is to use one or two mercury high intensity discharge lamps, which can be purchased fairly inexpensively (~$20 each). However, the 300-1000 Watt lamps I am looking at (Plusrite 2310 – 1000 Watt – Mercury Vapor – 58,000 Lumens – 3900K – Coated – 58 Lumens per Watt – ANSI H36 | 1000Bulbs.com) don’t seem to have too many power supplies available. A web search reveals mostly overpriced power supplies for scientific use, etc.
I am a beginner in electronics, so my current knowledge is limited. Does anyone happen to know of (1) any affordable power sources that could be used with these lamps (2) some sort of DIY circuit diagram for how to build one? It doesn’t need to do much, just turn the lamp on and off.
Thanks in advance!

3 Beach Reads That Will Make You a Way Better Investor

By Michael Lewis

Best investing books

Filed under: , ,

AOL

For those who have had the pleasure of completing an undergraduate finance program, it is a mild surprise (to say the least) to find that the real world of finance and investing is quite different from the efficiency-laden lessons of academia.

While this is frustrating to those who paid the price in time an tuition, it should be encouraging to the average investor who has no formal education in the subject. The truth is, right now, retail stock pickers have the same tools and tricks available to them as the world’s most successful investors.

So, in the spirit of summertime leisure, here is a hot list of books for investors that will get you on par with the very best.

The Classic Text

To recommend “The Intelligent Investor” is by no means a novel idea (pun absolutely intended), but it is, by far, the greatest quick read on the subject of stock picking. Written by Warren Buffett‘s mentor, Benjamin Graham, “The Intelligent Investor” provides the mental lattice all investors would do well to cling to.

Sure, the book champions value investing, which is not the only way to invest, but it can help investors of all kinds — even those interested in the next big technology winner.

Graham spells out the difference between speculation and investing — a concept that is often cited but which few seem to truly espouse. The Columbia professor and investing guru uses the allegory of Mr. Market to describe the battiness of the public markets, and how you can use that to your advantage.

While academic finance touts Efficient Market Theory — the idea that securities are priced with near perfection at all times — Graham posits nearly the opposite: Stocks can fall out of favor for reasons that do little to reflect the intrinsic value of a company — creating a price rift. Graham, Buffett, and the majority of the world’s greatest stock pickers believe that stocks drift toward that intrinsic number over time. Their track records support the claim.

With clear explanations of concepts such as margin of safety and defensive investing, “The Intelligent Investor” should be No. 1 on every investor’s reading list.

The Everyman Investor’s Bible

Peter Lynch, vice chairman of Fidelity’s investment advisory and former manager of the Fidelity Magellan Fund — the strongest performer of its (and his) kind from 1977 to 1990 — is great at writing simple, actionable investment lessons.

“One Up on Wall Street” is the shining example on the subject of DIY investing.

Though “The Intelligent Investor” is itself a very readable, simple book, Lynch’s classic explains in plain language strategies you may already employ. For example, Lynch loves “buy what you know,” the art of walking down the street and observing which brands are moving fast and which stores have lines …read more

Old House, New paddle fans

By Dan in VA

Hello all! I am new to this site. What a great resource for the DIY’er!

I purchased a house built in 1941. I want to replace the ceiling light in my bedroom with a paddle fan and light. I took off the light fixture and found this box, with a large threaded pipe in the center. Is this strong enough to hang a paddle fan on? I have no access to the box in the attic, due to duct work built over the top of the box. It sure looks sturdy, but I don’t want to sleep under it without knowing if it is a good idea or not! 😮

Here is a photo, showing the threaded pipe. Any thoughts and/or advice is appreciated!

Concrete mixer for mortar?

By arc2v

So it’s settled. Since the only quotes I got were $4k for my walkway (paving stone over concrete), it’s officially a DIY job. I’m comfortable with the work, it’s just the time I was hoping to save, but not at that price.

Got the Type S mortar mix, cuts and layout ready — just planning to get ready for when the temps drop down to the 80’s instead of the 90+ range.

So, for a Type S mortar used in the setting — rent a small concrete mixer? One wheelbarrow at a time?

For time reasons, I’m only looking at doing about 25 sqft at a time (and taking my time). But if the mixing is easier and keeps longer to let me work slower, then I’ll pursue it.

Thanks.

How to Make a Super Cheap One-Way Check Valve

If you’re going to build yourself a water gun to cool down this summer, or maybe just a useful water pump, you’ll need some check valves. However, the most expensive parts of a water pump or DIY super soaker are usually the check valves. So, let’s make some from scratch for as little as $0.35 each.
Video: .
These should work for you PVC building enthusiasts!

WARNING

The pressure tests and claims made on these check-valves are based solely on my personal experiences with the ones demonstrated in the video. Individual results may vary, and caution and care should be taken when loading the… more

Ductless A/C Units

By Roger2561

Hi folks, I live in NH in my folks old farmhouse (both gone now). Although I spent quite a bit of money insulating it, it gets hot in there in the summer. Can you offer up your opinions (pros and cons) on the ductless A/C units where it’s basically a DIY’er install? I do not want a window unit due to back problems and having difficulty lifting things. I’m leaning toward purchasing a 14,000 BTU unit for the common space. All I want to do is lower the temp to some where around 75 degrees from the 90 degrees it gets in there. Thanks in advance for your help. Roger

I'm thinking DIY Whole House Window Fan

By dagregster

Hi Folks,

My 3rd floor in my small stone twin has a cathedral ceiling with no attic or soffits to speak of. I have been looking at the Air King window fans but was also wondering if anyone here has tried building a DIY whole house window fan. My thought was to use something like an Air Vent Gable fan and mount it in a box with a screen, some sort of switch that can contol speeds, and of course, a screen. This would then git perfectly in my 25″ wide double hung window otherwise, I would have to go to great pains to retrofit the Air King.

Another way might be to have my roofer install a roof mounted type fan but they don’t seem to move as much air. My roof is asphalt on wood (1″ thick) with about 8 inches of insulation, then drywall.

I would appreciate any thoughts or suggestions on a way to proceed here. My goal is to pull as much air as possible through the house but also to have it be not too noisey as the 3rd floor is one big room and that is our family room. Is there a product that I should look at? What about my DIY fan idea?

Thanks so much!

Greg

Well used for lawn will not shut off

By smietana

Well will shut off when using the automatic sprinkler system. However, when using the hose/faucet, it will continue to run after the hose/faucet isn’t in use. Also on the rare times that the pump starts do to low pressure, it may or may not shut off. To date I have done the following:

Changed pressure switch with one from working system. Symptoms remain.

Changed air bladder with one from working system. Symptoms remain. (Pressure was set 2 pounds below cut-pressure of 30

Eliminated air bladder completely. Symptoms remain.

When off this system’s pressure remains steady for an extended period which eliminates a leak.

I am out of ideas and would appreciate feedback if anyone has experienced this.
It seems to me I have addressed the obvious, but I am only a pretty good DIY guy without a lot of well experience. thanks in advance.

New House – New to Central AC and Yearly Service Advice

By bryankloos

Hi Guys,

I’m in a new home with Central AC. This is my first experience with central AC.

I have 2 units, one in the attic and one in the basement handling the second and first floors. Both are Trane and about 8 years old.

The condensors seem clean though I haven’t pulled a cover to fully inspect the insides.

The air handlers have old electric filters with only pre-filters though they were turned off when we moved into the house. I’ve since cleaned the pre-filters though the electric grids are clean. I’ve looked at the evap cores and they seem fairly clear. I haven’t looked at the blower motor yet…

I’m a fairly handy DIY guy who usually never outsources home work unless absolutely necessary. I’d rather buy the tools and learn from the web and here and learn the skill and pass it along to others.

That said, what am I looking at relative to maintenance for the units? What is the frequency and what needs to be addressed. Are there any special tools that I will need and what parts of the service are beyond my scope…?

Looking forward to learning along the way.

Thanks,

Bryan

How to Make a Solar-Powered Fan Hat

It’s hot this summer, but it’s not that easy to cool down when you’re on the go. You can’t take an air conditioner with you, and a handheld fan will just tire you out, so you’ll need to find more creative ways to cool down when you’re on the go. One of these ways is a DIY solar-powered fan baseball cap.

A small solar cell is sewn into the crown of the hat which collects the sun’s energy, and converts it into electricity that powers the small personal fan built into the front bill. This is a really cool solar idea; especially on the hottest, sunniest days when you must wear a hat to protect… more

Brand New Disposall Leaking from the bottom

By DIYNovice76

I just installed a brand new GE Disposall. I ran water and ran the disposal to test for leaks and it was completely dry. I was so proud of my first DIY plumbing project. But, several minutes later (at least 10 – 15 minutes), the disposal leaked from the bottom. I’ve read that it might be a bad flywheel seal, but this is a brand new disposal. Could there be any other explanation? Any tips on fixing this leak? The thing that seems so strange to me is that it doesn’t leak at all while the water is running.

Thanks for any help!

How to Make a Shotfun (A Double-Barrel Shotgun That Shoots Party Poppers)
