  • How To Stay Sane in a World Gone Mad - by Jamie Paul

    Being principled ultimately means that your loyalty to principles has to supersede your political or tribal loyalties. Something you hate when “they” do it has to be just as distasteful when “we” do it. Humans are not born with these habits of mind. They require cultivation, and the very picosecond you begin making that effort, you instantly vault ahead of 90 percent of humanity who make no such attempt. Every time you feel a strong opinion form in your mind about some issue, press pause and ask yourself “Does this jibe with my principles? Does it contradict other things I believe?” Become interested, even fascinated, with the question “Am I a hypocrite?” I reflexively ask myself this easily a dozen times a day. The answer is still yes, but I’m definitely less of a hypocrite than I used to be because of it. At bottom, it begins, as all worthwhile things do, with giving a shit.

  • Reverse engineering the 59-pound printer onboard the Space Shuttle

    This printer is known as the Space Shuttle Interim Teleprinter System. As the name "Interim" suggests, this printer was intended as a stop-gap measure, operating for a few flights until a better printer was operational. However, the teleprinter proved to be more reliable than its replacement, so it remained in use as a backup for over 50 flights, often printing thousands of lines per flight. This didn't come cheap: with a Shuttle flight costing $27,000 per pound, putting the 59-pound teleprinter in space cost over $1.5 million per flight.

    I had to reverse engineer three of the boards inside the printer to determine the data format the printer accepted: serial data encoded into audio. But after analyzing the printer and performing a lot of maintenance, we succeeded in getting the printer to print.

    the teleprinter implements a word processor, allowing messages to be composed and edited offline. Of course, since the Shuttle's teleprinter is only used to receive data, and doesn't even have a keyboard, the word processor feature is entirely useless. ... According to the manual, the printer operates fine without this card, except without the word processor. Since the word processor was irrelevant to the Shuttle, I wonder why this card wasn't removed to reduce weight.

    The hammers have an unusual constant-current power supply. When the printer is active, this power supply generates +18 V. However, the power supply is designed to use a constant current of 600 mA regardless of the hammer activity. A capacitor provides a reservoir of power that is filled by the constant current. If the hammers are using less current, the excess current is bled off through a resistor. The purpose of this is "to mask printing intelligence during periods of message traffic." In other words, if you used a teleprinter in the embassy in Moscow, for instance, spies could monitor power transients to see when hammers are firing, and perhaps figure out what is being printed. By keeping the current constant, this source of intelligence is blocked. Of course, this feature is useless on the Space Shuttle and only wastes power.

    At first, I thought that the Shuttle's Interim Teleprinter was a terrible design. It's absurdly heavy and was in danger of overheating. Although the design started with an existing product, much of it required redesign: the front section, the new drum, the interface, and even the frame. The design inherited features it couldn't use, such as the built-in word processor. And the constant-current feature was pointless for the Shuttle and just wasted power.

    When I learned that the design had to be completed in just seven months, my opinion of the teleprinter improved. Moreover, the design had many constraints, such as toxicity and flammability restrictions, that limited the potential approaches. In the end, the teleprinter was used on over 50 flights, acting as a reliable backup to the somewhat flaky Text and Graphics System (TAGS).16 Despite its name, the Interim Teleprinter turned out to be a long-lasting solution, not interim at all. So I have to conclude that the teleprinter was a good design, working much better and much longer than intended.

  • Secret Service’s Tech Errors Helped Gunman at Trump Rally Slip By - The New York Times

    The Secret Service, for instance, turned down offers to use a surveillance drone at the Butler Farm Show rally site. The agency also did not bring a system to boost the agents’ device signals in an area with poor cellular service. And some of the equipment the agency did bring, including a system to detect drone use by others, did not work when it was most needed. The result was that a 20-year-old gunman had a technological advantage over a $3 billion federal agency. The acting Secret Service director, Ronald Rowe Jr., told Senate lawmakers in a hearing this week that the agency had the tools that could have spotted Mr. Crooks and allowed agents to interrogate him before the shooting, but failed to properly use them.

    Mr. Trump was injured in the shooting, as were three rally attendees, one fatally, in one of the biggest failures of the Secret Service in decades. Mr. Rowe, in his testimony, said that he could not understand why the Secret Service chose to exclude the warehouse Mr. Crooks used, about 450 feet from Mr. Trump’s lectern, from its secure perimeter and why no countersniper was assigned to its roof.

  • Trump to debate Harris on Sep 4th

    I have agreed with FoxNews to debate Kamala Harris on Wednesday, September 4th. The Debate was previously scheduled against Sleepy Joe Biden on ABC, but has been terminated in that Biden will no longer be a participant, and I am in litigation against ABC Network and George Slopadopoulos, thereby creating a conflict of interest. The FoxNews Debate will be held in the Great Commonwealth of Pennsylvania, at a site in an area to be determined. The Moderators of the Debate will be Bret Baier and Martha MacCallum, and the Rules will be similar to the Rules of my Debate with Sleepy Joe, who has been treated horribly by his Party – BUT WITH A FULL ARENA AUDIENCE!….
