During an internal training exercise today, as a sort of one-man Chaos Monkey, I de­lib­er­ate­ly broke a test system by changing a config setting to read:

itemfinder.url = http://test-іtemfinder.example.com/

The correct value should have been:

itemfinder.url = http://test-itemfinder.example.com/

What’s that, you say? There’s no difference, you say?

There is a difference, but it’s subtle. The first i in the URL is ‘CYRILLIC SMALL LETTER BYELORUSS­IAN-UKRAINIAN I’ (U+0456), not ‘LATIN SMALL LETTER I’ (U+0069). Depending upon the font, the two is may be visually in­dis­tin­guish­able, very similar looking, or the Cyrillic i may not render.

This is an example of an In­ter­na­tion­al Domain Name Homograph Attack. There are Greek letters and Cyrillic letters that look very similar to Latin …continue.

I was in­ves­ti­gat­ing the per­for­mance of a web app today, and I spent some time looking at the Flame Chart vi­su­al­iza­tion in Chrome’s profiling tools, which helped identify some problems.

Flame Charts are like Brendan Gregg’s Flame Graphs, except that the charts are sorted by time, while the graphs are sorted al­pha­bet­i­cal­ly.

Quoting from Gregg’s recent ACM Queue article:

A flame graph has the following char­ac­ter­is­tics:

• A stack trace is rep­re­sent­ed as a column of boxes, where each box represents a function (a stack frame).
• The y-axis shows the stack depth, ordered from root at the bottom to leaf at the top. The top box shows the function that was on-CPU when the stack trace was collected, and …continue.

Flashman At The Charge finds our hero, newly promoted to Colonel, nurse­maid­ing a minor Royal cousin in the Crimean War. Somehow he finds himself in the thick of the Charge of the Light Brigade, which he survives only to be taken captive by the Russians. Sent off to Count Pencher­jevsky’s estate, he luxuriates there for some time, bedding the count’s daughter Valla. When he and another British officer overhear the Tsar discussing Russian plans to invade India, he re­luc­tant­ly escapes. After he is captured …continue.

In Jason Bourne, the eponym is back in action, running around the planet in a personal vendetta with the director of the CIA. Bourne’s old ally Nicky Parsons is killed trying to pass him some in­for­ma­tion that she’s unearthed about the Treadstone program that turned David Webb into the amnesiac assassin known as Jason Bourne. The CIA director sends a killer known only as the Asset after Bourne, while the fresh-faced head of the Cyber Ops division does her best to keep Bourne alive.

This is a largely un­nec­es­sary sequel to the Bourne franchise. While the …continue.

If you know exactly which line you want to go or which pattern you want to search for, Vim provides a couple of command-line options that can help: +NUM goes to line number NUM, while +/PAT searches for the first occurrence of PAT. It’s also possible to execute an Ex command with +CMD, such as "+set fenc=latin1". You can supply up to ten + options.

Detective Inspector Ben Cooper, newly promoted, is leading the team that’s in­ves­ti­gat­ing the murder of a lorry driver outside a remote Peak District village. It seems to be connected to a suicide that took place the same day, but how? Cooper and his team manage to peel back the layers sur­round­ing the dual mysteries.

Booth writes solidly plotted, solidly char­ac­ter­ized novels, and this is another good entry in his long-running Cooper & Fry series.

I assembled an outdoor dining table on Sunday, and belatedly realized that I had used only half the washers. The unclear directions had said to place one washer next to the bolt head and the other washer at the far end, just inside the nut. I had overlooked the latter. I don’t feel like undoing twelve bolts and starting over, so it will stay that way.

It occurred to me to wonder what purpose the washer serves. I had a notion that, since it increases the apparent area of the bolt head or the nut, it must reduce the pressure on whatever is being tightened by the bolt in the immediate …continue.

Flashman And The Redskins is the seventh volume of the Flashman Papers, although it opens im­me­di­ate­ly after Flash For Freedom! In the first part, which takes place in 1849–50, Flashman is fleeing from New Orleans in the company of a madam who is taking her entire brothel westward to take advantage of the California Gold Rush. He sees the opening of the West and the beginning of huge changes to the Plains. He is taken captive by Apaches …continue.

Jack Holloway is a prospector on Zara XXII, con­tract­ing for the giant ZaraCorp. On one momentous day, he is fired, discovers a huge seam of sunstones worth trillions, and meets the first members of a new species, the fuzzies. Since he was fired before he discovered the sunstones, he now has an en­force­able claim—and he’s a disbarred lawyer, so you can bet he’s following through. The fuzzies are delightful and they’re pretty smart—so smart that they might just be sapient. And if they are, that’s a huge problem for ZaraCorp, since the fuzzies …continue.

AIDS decimated the gay community in the 1980s and early 1990s before effective treatments were developed, and AIDS and HIV continue to affect the LGBT community dis­pro­por­tion­ate­ly. I personally have walked in the Seattle AIDS Walk every year since 1992.

Please sponsor me at https://give.lifelong.org/georgevreil­ly I am also the captain of the Freely Speaking Toast­mas­ters team and we’d love to have you join us.

Any money you donate or raise will support people in King County who are living with HIV or AIDS. It will help feed them, pay for medicine, and prevent further infections.

I’ve walked for 25 years to honor the living and the dead. I’ve known people who died of AIDS …continue.
