For the Spelling Bee, 472k Words May Not Be Enough

Linda Tarrant, one of the nation’s foremost spelling coaches, said her company’s programs run at least eight weeks, with one hour of coaching each week by Skype or phone. “We teach vocabulary skills,” said Ms. Tarrant, who leads Hexco, a Texas-based company, and coached her three children in spelling. Still, some people fear that the financial costs associated with spelling bees — travel expenses that can climb into the thousands of dollars and coaching bills that can run well into five figures — may be changing the character of the competitions.

Wood Joint Strength Testing

Wood Joint Strength Testing

The mortise and tenon joints averaged 172 pounds, whereas the dowel joint averaged 135 pounds. My pocket hole joints failed at just 115 and 110 pounds, with the 2″ #7 screws pulling out of the post. Overall, the hardwood mortise and tenon and dowel joints showed a minimal amount of deflection before failure, whereas the spruce joints deflected a bit before the point of letting go.

HN: The Good Parts

HN: The Good Parts

If you read HN, on any given week, there are at least as many good, substantial, comments as there are posts. If you just read HN, it’s hard to see the effect, but if you look at forums that use comments as a positive factor in ranking, the difference is dramatic — those other forums that boost topics with many comments (presumably on theory that vigorous discussion should be highlighted) often have content-free flame wars pinned at the top for long periods of time. Having flamebait drop off the front page quickly is significant, but it doesn’t seem sufficient to explain why there are so many more well-informed comments on HN than on other forums with roughly similar traffic.

keyboard layout that changes by markov frequency

Static keyboard layouts are boring and predictable. The layout will update itself to move the keys that most frequently come next to the home row. There are minor challenges involved if your keyboard layout could change with every keypress, thus this prototype is an emacs library that displays and updates the current layout with every keypress.

Japan mandates cars to be 30% more fuel efficient by 2030

Japan mandates cars to be 30% more fuel efficient by 2030

The new standards released Monday call for average fuel economy of 25.4 km per liter of gasoline across total vehicle sales for a given company, up 32% from the fiscal 2016 performance. Just 24,000 electric vehicles were sold in Japan during fiscal 2017, accounting for 0.5% of all new-auto sales, industry ministry data shows. Honda Motor plans to roll out its first mass-produced fully electric vehicle in Europe and Japan next year, and the company looks to have electrics and fuel cell autos account for 15% of its 2030 sales.

Windows Exploitation Tricks: Abusing the User-Mode Debugger

Windows Exploitation Tricks: Abusing the User-Mode Debugger

See if you can spot the problem with the following code snippet from that function:

The result of this behavior is given a process handle with it’s possible to use that to get full access to the process and initial thread even if the objects wouldn’t grant the caller that access. Well I would expect the caller would need to have opened suitable process and thread handles before attaching the debugger and use them to access the target, or if the kernel has to create new handles at least do an access check on them. The file handle is opened when attaching to the process and uses the following code:

This code is careful to pass to the file open call to ensure it doesn’t give the debugger access to arbitrary files.

The Prince of Quacks and How He Captivated London

The Prince of Quacks and How He Captivated London

Guests were paraded past one electrical marvel after another: flint glass jars blazing with captive sparks, gilded dragons breathing electrical fire, a gilded throne on which Graham’s patients sat to receive their curative shocks. The most infamous feature of the Temple of Health was Graham’s Celestial Bed. With his devices and his medicines, Graham claimed to have “an absolute command over the health, functions and diseases of the human body.”
