Hack a Day: Untitled

[Patrick] decided to make a computer controlled etch-a-sketch. While the idea is not that new, there is always a different way to accomplish a goal. An Arduino is used to control a pair of stepper motors which were sourced for pretty cheap, and even came with their own driver. Next a stand was mocked up using foam board, which helps determine where all the parts should live.

Next was a way to attach the steppers to the knobs, gears would be used and a collet meant for model airplanes was sourced to make the mechanical connection between gear and shaft. With everything set in place via foam board and paper printouts, it is off to get some thin plywood. The plywood is sent though a laser cutter creating most of the stand and gears. Now its all software, a program was whipped up for OSX which converts low res pictures into squiggly lines perfect for the etch-a-sketch to draw on its screen.

The results are quite impressive, join us after the break for a quick video.

The Daily WTF: CodeSOD: Dirty Code

Ever since being hired, Adam had spent most of his time working on new projects.

He was aware that there was an "old system" running out there and would someday be shut down and his efforts were to help this come about, but he never had the opportunity to cross paths with it.  Based on what he had heard though, this was a very, very good thing.

However, once Adam had earned a reputation of his own of being a good problem solver, he was soon asked to peek at the "old" (ok, current) system and see how it worked. You know, the in lieu of a functional design document, he received the order "Just make it work like it does now".

In the one source file he was on, Adam quickly found the following which he considered to probably be the finest bit of coding he had ever seen.

//These fucking wankers wanted it unfucked 
private bool un-fuck(int fuck-v) {
   if (fuck-v == 1)
   {
    return true;
   }
   else
   {
    return false;
   }
}

And it didn't stop there. After a quick search he found 20 shits, 25 fucks, 15 bollocks, and 8 assholes in the rest of the code.  The swear words were found mostly in the comments, but he did find some cases where the arrangement of variables and function names made for some rather "interesting" business logic.

This of course left Adam with a small dilemma - how does one document something that is not safe for work?

Crooks and Liars: Dana Loesch Pimps Discredited Pro-Life 'Sting' Of Planned Parenthood

Dana Loesch Pimps Discredited Pro-Life 'Sting' Of Planned Parenthood

Click here to view this media


(h/t Heather at VideoCafe)

Why-oh-why is Dana Loesch being invited on the Sunday news shows? The Editor-in-Chief of Breitbart's BigJournalism site deserves no such association with either honest brokers or journalism. Actually, considering the larger panel discussion on the Susan G. Komen controversy and the massive amount of misinformation muddying the issue by Matthew Dowd and George Will, honest brokers and Sunday morning news shows have very little to do with one another either, but I digress.

Loesch is particularly worthy of scorn because she uses a discredited "sting" by the discredited Live Action organization, led by the discredited Lila Rose to amplify her point:

Now, you would think at some point in the past — it's been a year to the date since Live Action called Planned Parenthood clinics in 27 different states to ask whether or not they had mammography machines. You would think that at that point — they'd had a year — Planned Parenthood would invest in obtaining licenses to operate and own mammography machines and give mammograms so they could have avoided this whole thing.

Yeah, about that lack of mammography machines ... turns out, the whole thing was a sham.

HOAX EXPOSED: Rose's Video Does Not Establish That Planned Parenthood Ever Discussed Mammograms Provided By The Organization

Richards Discussed "Access" To Mammograms Through Planned Parenthood - Not Mammograms Actually Provided By The Organization. In the video at the center of Rose's hoax, Planned Parenthood President Cecile Richards discusses access to health care - including mammograms - not actual health care services provided by Planned Parenthood. Discussing GOP efforts to defund Planned Parenthood during an appearance on The Joy Behar Show, Richards said:

If this bill ever becomes law, millions of women in this country are going to lose their health care access, not to abortion services, to basic family planning. You know, mammograms, cancer screenings, cervical cancer. [CNN, The Joy Behar Show, 2/21/11, via Nexis]

Pro-Life Activist Jill Stanek: Richards Was "Correct." From Stanek's blog:

Richards said:

If this bill ever becomes law, millions of women in this country are going to lose their health care access, not to abortion services, to basic family planning -- you know, mammograms, cancer screenings, cervical cancer.

The fact is not one Planned Parenthood in America performs mammograms. All PPs do are refer for mammograms.

Conservatives want to obfuscate the issue. Komen didn't retract funds because Planned Parenthood doesn't offer mammograms. It never has. I've had a wellness check-up from Planned Parenthood (I was between jobs and didn't have insurance for about a year) and it included a manual breast examination as well as instructions on the proper methods of self-examination (an important tool in early detection, which leads to higher survival rates). Had they detected anything or if I had belonged to any of the high risk groups, they would have referred me for a mammogram. That service could save potentially thousands of women's lives.

And waste-of-intelligence hack pundits like Dana Loesch want to keep that from them.

Cool Tools: Wind Chimes: Design and Construction

Make your own. Not those tinny flea market varieties, but large striking sonorous chimes tuned in all manner of unusual styles. (Listen to samples on the book’s website or included CD). There are several dozen unusual ways to tune the chimes. All tunings are fairly mathematical, which is the core of this book, but not difficult to execute with hardware-store tubing. My son and I used this short but very explicit manual to create a large copper pipe one that emits a lovely melody in the breeze. The bigger the better. (The bigger the more wind they need, too.) This guide is a very practical way to experience the math of music and the beauty of alternative music systems.

Groklaw: Oracle v. Google - Still Waiting on the Revised Cockburn Report

Although Dr. Cockburn's third attempt at a damages report was due to be filed last Friday, February 3rd, it has yet to show up on the electronic docket. That is most likely due to its length and the possibility that Oracle will seek to redact portions of the filing. In the meantime, Judge Alsup has issued a clarifying order with respect to the trial briefs on the issue of copyright. (710 [PDF; Text]) The judge basically instructs the parties to not interpret the law for him but to set out the relevant passages so he may draw his own conclusions. In addition, he wants the parties to make clear where they agree on the underlying law.

We also have the transcript of the July 21 Daubert hearing on the first Cockburn damages report. (Text of Document 231) You will recall that it was at the conclusion of this hearing that Judge Alsup ordered Oracle and Dr. Cockburn to go back and try again with something closer to a more reasonable assessment of damages. (Damages Report - Try Again, Oracle) We now get a better insight into the arguments set forth by Google in attacking the original report.

Modern Mechanix: The Drive-In is Thrivin’ (Aug, 1951)

The Drive-In is Thrivin’

America’s newest major industry was regarded as a newfangled novelty a decade or so ago. Now it’s become strictly big business.

By I. B. Neer

WITHOUT leaving the wheel of your car you can spend the most amazing vacation of your life this summer. For the drive-in is really thrivin’!

Without sliding from behind the steering wheel, you’ll be able, to deposit money in a bank, do all your shopping in supermarkets, buy a bouquet of flowers, mail a letter, go to church, pay your gas and electric bills, have prescriptions filled, get your laundry and dry cleaning done, take out insurance, check into a hotel, visit a zoo, have your shoes repaired and buy a bottle of Scotch for the long cool nights.

The drive-in as a big business may appear to have burst suddenly on the American scene, but actually the trend was being developed for more than 20 years. A few roadside restaurants made their first inquiring venture into the feed-’em-on-the-run field in the mid-20s and found it paid off handsomely.

Then businessmen in the cities, searching for a solution to the parking problem, took a cue from their country cousins. They started to convert their facilities so that motorists would be spared the wearisome hunt for an open spot on the traffic-choked streets. Again car owners hailed the innovation and before long Yankee ingenuity had developed a new industry.

Look what happened at Jackson Hole Wildlife Park near Moran, Wyo. On hand was the nation’s largest assortment of native big-game animals—buffalo, deer, elk, moose and antelope, last remnants of the vanishing American herds. The officials thought long and hard and finally leaped on the drive-in bandwagon as the best way to give tourists a real close-up of the animals in their native habitat.

Accordingly, they veined the large wooded area with a network of roads and strung almost invisible fences through the fields which keep the animals constantly in sight of motorists driving past. The herds cannot escape the enclosure because of a tricky device at the entrances. Timbers, criss-crossed along the first few yards of roads, are easy for a car to traverse but impossible for an animal.

Four years ago the Rev. Norman L. Hammer of North Hollywood, Calif., decided to do something about the 40 per cent slump in summer attendance at his Sunday services. Making a sort of one-man Gallup survey, he’ found that his parishioners were tempted by picnic grounds, beaches and golf courses come Sundays. Dressing for church, then rushing home to get into play garb, took too much time. So the pastor met his flock halfway.

He fitted up a pulpit in a parking lot behind his church and spread the word that parishioners could drop in on their way to play. First outdoor service was held on July 6, 1947, and soon swank convertibles and wheezing jalopies were pulling in side by side for Sunday morning worship.

Says the pastor with a twinkle in his eye: “The outdoors gets them on Sundays, but we get them first.”

Perhaps the most surprising development in the spectacular growth of the drive-in industry is the fact that such conservative institutions as banks have joined the parade. Eyebrows flew upward in financial circles back in 1936 when the City National Bank of South Bend, Ind., set up a teller’s window facing an alley and announced it was open for curb-service banking. But the idea took root and, according to the American Banking Association, has now spread to more than 500 institutions in 18 states.

The country’s largest and most elaborate drive-in bank is the Exchange National Auto Bank of Chicago, 111., where an average of 600 cars purr past the tellers daily, making 40 per cent of the total deposits. It is constructed in the shape of a huge U surrounded by driveways with ten tellers’ cages in the center. Attendants funnel the cars to the windows and tellers push out metal drawers into which customers drop money, bankbooks and necessary papers. Tellers and depositors communicate through a loudspeaker and microphone arrangement. If the services of a bank officer are needed, the tellers shoot him the papers via pneumatic tubes.

Drive-in theaters have come a long way since the first was opened strictly as a novelty outside Camden, N. J., in 1933. Hit by an almost disastrous slump during the war, they bounced back to the point where in Denver 7,000 persons waited two hours to see a movie, the first world premiere ever to be shown in a drive-in.

Some drive-ins which know all about baby sitting and home-chore problems, cheerfully tell patrons not to stay home on those accounts. They supply nurses and bottle-warming equipment and even do the family laundry while the show is on. The patron deposits a bundle of wash when he enters and gets it back clean when he leaves.

Rainy, windy or foggy nights used to strike deep gloom into the ranks of drive-in owners, but they don’t any more as the battle against the elements is being won. Scientists have now developed a glycerine compound which is sprayed on car windshields to drain off the downpour in transparent sheets instead of driblets. Steel reinforcements keep the huge 50 by 60-foot screens from swaying or toppling in high winds. DDT has banished the mosquito plague and fog-filters have been perfected so that projectionists can sharpen the picture when the mists descend.

The drive-in-and-dine spots come in two models—those in which cute car hops clamp food-laden trays to the car doors, and fully automatic ones which do away with waitresses, tipping and leg work. Perhaps the world’s biggest and swankiest drive-in beanery is the $750,000 edifice near downtown San Francisco, which sprawls over one and one-eighth acres and employs nearly 200 persons, including four traffic cops who flag customers into spots along the 250-car parking area. It serves more than 7,000 meals a day from two huge kitchens, filling each order in an average of six minutes. Otto E. Straub, the builder, spent eight years in an intensive study of food drive-ins before launching his enterprise.

The Motormat in Los Angeles, the first fully automatic drive-in restaurant, served 10,500 meals in its first nine days of operation a few years ago. A motorist parks in one of 20 stalls which fan out from a central, glass-enclosed kitchen. As he slips into place, a bin shaped like an old-fashioned breadbox shoots out from the kitchen on a runner and stops at the car door.

Inside the bin are glasses of water, a menu, a pad and pencil. The customer writes his order, pushes a button and the bin scoots back into the kitchen. In less than a minute, back comes the bin with the bill which must be paid before the meal is served. On its third trip the bin brings the order plus change.

With skyrocketing demand, there appears to be no limit to the types of business flocking to cash in on the curbside gold rush. The National Institute of Cleaning and Dyeing reports that roadside dry-cleaning places are opening by the dozen each week. Laundry field experts say that ten per cent of the nation’s laundry business is now transacted at windows which open on a driveway.

In many communities you can roll into a supermarket and make all your purchases without leaving the car. A California market sports a huge sign at the entrance: “If you don’t see what you want, just keep on driving until you do.”

Even the U.S. Government has become aware of the trend and stepped into line. In many cities, the post office has installed curb-side mailboxes with large gooseneck openings into which drivers can deposit mail without dismounting.

There’s really no end to the variations. The Detroit Edison Co. has opened an office where motorists can drive in, pay bills, leave appliances for repair, arrange for service and drive out. A number of insurance firms have set up offices in driveways and a drive-in night club is doing thriving business in Los Angeles.

In Beverly Hills, Calif., a drive-in liquor store has one rigorous rule. When a customer drives up, the salesman steps out, takes a good look and a big sniff. If he detects any tipsiness whatsoever, he sends the driver on his way. The store won’t sell liquor to drunks.

So, if you’re planning to hit the road this summer, don’t worry about missing the comforts and luxuries of home life. You can get ‘em in drive-ins. All you need is the car, the endurance—and the money. •

Modern Mechanix: Understanding LAWS of SCIENCE (Dec, 1961)

Understanding LAWS of SCIENCE

—is easiest when an experiment shuts out all extraneous effects and lets one principle alone shine through. Try these six simple demonstrations to see how strikingly clear their principles become To demonstrate why exposed airplane parts are streamlined or given a tear-drop shape, place a piece of cardboard, bent into such a shape, in front of a candle as shown. Now blow at the rounded end of the model. The air from your breath follows the form and blows the candle flame straight from you, almost as if the obstacle were not there.

Blow at a flat piece of cardboard held in front of the candle, however, and the flame blows toward you! Instead of flowing smoothly around the flat card, the air flows turbulently past it, creating a pocket of low-pressure air behind the card. If permitted in airplane design, unstreamlined parts would create similar pockets behind them, interfering seriously with plane movement.

Why do you need more power to start your car than to keep it going at moderate speed? You can get an idea by pulling a weighted toy truck with a rubber band. If you pull gently the band will stretch considerably before the truck starts at all. In the photo the car has not yet started to move.

But once the car starts moving, the band contracts, proving that less force is needed. The reason for this effect is that inertia and static friction unite to resist motion when the truck, or your car, is standing still. When the truck is moving at a constant speed, the only resistance encountered is that of rolling and sliding friction, which is much less than the original static friction.

By suspending two metal plates at opposite sides in a glass of water and connecting them in series with a small electric light bulb and several dry cells, you can readily divide all water-soluble substances into electrolytes and non-electrolytes —substances that form solutions that conduct electricity and those that do not. Add sugar to the water, for instance, and the light does not glow, indicating that sugar is a non-electrolyte.

Add salt to the water, however, and the bulb glows brightly, proving that a salt solution is an electrolyte. You can test other substances similarly. Substances which form electrolytes break up into ions when dissolved in water. It is these ions that carry the electric current.

Because of surface tension, liquid bodies freed of all distorting forces tend to become spherical—a sphere having the smallest surface for a given volume. You can demonstrate this by floating drops of cooking oil in an alcohol-water mixture. Using a flat-sided bottle, fill it two-thirds full of rubbing alcohol and into this put a few drops of the oil. Slowly add water until the drops descend part way into the mixture. To prove the drops will remain spherical regardless of size, enlarge some by injecting more oil into them with a medicine dropper.

Can you fill this modernized version of the Cup of Tantalus? Legend has it that this cup suddenly emptied itself just before reaching the parched lips of the king for whom it was named. Bend a glass or plastic tube in the shape of a question mark, as shown. Then slip a short piece of rubber tubing on the bottom end and press the rubber into the stem of the funnel. The funnel will now hold water until it rises to the top of the bent tube. At this point, siphon action starts and the water drains out. Consequently, if you pour slowly enough, the funnel will never fill up.

You can easily demonstrate the curious fact that heat waves from the Sun, from electric light bulbs, and from other bodies at extremely high temperatures can pass readily through glass, while waves from less highly heated bodies, such as radiators and electric irons, can do so only with difficulty. Set up two sheets of glass as illustrated. Facing one sheet, place an electric iron; facing the other, an electric light bulb. If you now put your hand between the sheets, you can instantly note the difference. The side of your hand facing the light bulb will feel much warmer than the side facing the iron, although the latter is actually giving off a great deal more heat.
