What is the practical difference among same-wattage PC power supplies?

I have a three-year-old PC with a Corsair AX760i 760W power supply. It was a premium model at the time (2015), costing $183.

I left the PC plugged-in, but shut down, for a couple of days. When I returned and powered it up, the machine died after about 10 minutes of use, as suddenly as if there had been a power failure. After that, it wouldn’t start at all, seeming to start up and then shut down repeatedly at 1-2 second intervals. I left it unplugged overnight and the machine booted up and ran just fine all day.

I am thinking that it is time for a new power supply. In theory this thing has a warranty, but how can I live without it for days? Maybe they offer advance replacement? But how do they know it is actually broken and it isn’t something else shutting down the PC?

[Readers: Anyone have an idea for what could be wrong other than the power supply?]

Let’s assume that it is in fact time for a new power supply. The same company, Corsair, makes multiple 750-watt model: Bronze ($80), Gold ($130), and Platinum ($180). What is the conceivable practical difference among these? Will it be fan noise? They all claim to be quiet at idle, which is where my PC lives 99 percent of the time (Adobe Premiere compressing videos is my only heavy load). The high-end ones are slightly more efficient? But who cares if the PC is seldom under high load?

Thanks in advance for brilliant insights!

[Separately, I can’t see anything about today’s PCs that is significantly better than what I purchased three years ago (for a little over $2,000). The consumer (non-Xeon) motherboard in my desktop holds up to 128 GB of RAM (32 GB currently populated). Most of what’s in the market today seems to max out at 32 GB or maybe 64 GB. How is it that so many brilliant engineering minds can’t make something that inspires trade-ins?]

Modest requirements for an employer

From a Facebook friend:

I get so frustrated with operational problems at [the school where I work] that I sometimes think I’d leave if there was another Hispanic-serving trans-friendly women’s college in [the big metro area where I live] that would grant me tenure. (emphasis added)

If she ever does talk to a headhunter, I would love to listen in!

Passion for feminism not helpful when selecting romantic partners?

“Eric Schneiderman, Accused by 4 Women, Quits as New York Attorney General” (nytimes):

Eric T. Schneiderman, the New York State attorney general who rose to prominence as an antagonist of the Trump administration, abruptly resigned on Monday night hours after The New Yorker reported that four women had accused him of physically assaulting them.

Two of the women who spoke to the magazine, Michelle Manning Barish and Tanya Selvaratnam, said they had been choked and hit repeatedly by Mr. Schneiderman. Both said they had sought medical treatment. Another woman, a lawyer, said she was slapped violently across the face. A fourth woman said she had similar experiences.

Mr. Schneiderman has long been regarded as one of the state’s most progressive politicians, even before his 2013 lawsuit against Trump University and his subsequent suits against the Trump administration made him the darling of the political left.

One of the women, Tanya Selvaratnam, has “served on the board of The Third Wave Foundation, which is dedicated to youth activism and the feminist movement” and produced videos for the Women’s March. It does not seem unreasonable to describe her as a “feminist”. This New York Post article describes her relationship with the “progressive politician”:

Harvard-educated activist writer Tanya Selvaratnam told the New Yorker magazine that her yearlong affair with Schneiderman “was a fairytale that became a nightmare” — and quickly escalated into violence in the bedroom, even as he begged for threesomes.

“Sometimes, he’d tell me to call him Master, and he’d slap me until I did,” Selvaratnam said. … Soon, “we could rarely have sex without him beating me.”

I hope that we can all agree that this is a description of a below-average heterosexual relationship. The question then arises as to why an expert on feminism wouldn’t simply walk away from it. Can it be that years of studying feminism, marching, advocating, etc. have no practical value in this realm? If so, in what realm does being a feminist lead to a personal advantage?

[Separately, I know of a well-educated medium-income woman in her 20s. She was sufficiently passionate about feminism to go to the Women’s March in the off-the-charts-expensive city where she lives. She met a man in his mid-50s who owns a modest (i.e., $3+ million) house. She is now protesting the patriarchy by living in this man’s house.]

Blind tasting of $12 per bottle red wines

Friends run an annual blind wine tasting with $12(ish) bottles of red and one $40 “ringer” bottle.

In a field of about 15, the top-rated wine was Ava Grace Merlot 2015 from California, closely followed by a Moncaro organic Rosso blend from Italy and the $40 Gary Ferrell 2014 Pinot Noir (equalled by a Robert Mondavi 2016 cabernet; maybe the “private selection” that is about $11?).

People truly hated a popular Rioja and modestly priced Cotes-Du-Rhone and Bordeaux wines.

If you prefer wines crafted in Virginia you’ll be pleased to know that the Trump Winery’s 2014 Sparkling Rose earned 96 points in a competition in California (press release). From a recent Trump Winery email: “At the largest international wine competition in the world, our 2016 Sauvignon Blanc received a Double Gold medal with a 96 point rating. Of the nearly 200 Sauvignon Blancs entered from around the world, only 12 double gold medals were awarded: 10 from New Zealand, 1 from California, and ours!”

Identifying as a pilot

A new and wonderful turn of phrase in “Neighbors say it’s no surprise Lincoln County man crashed helicopter” (Fox 46):

An Iron Station man is lucky to be alive after his helicopter crashed and caught fire right on his front lawn.

Back in October, Timothy Kniess’ wife won the lottery a hundred thousand dollars on a scratch off ticket.

Luck was definitely on their side again today when he was able to escape the crash with just a few scratches.

Neighbors weren’t surprised by the crash. They say they watched Kniess attempt to fly his Mosquito XE helicopter for weeks, just waiting for it all to go wrong.

“Man bought a helicopter, he woke up one day and said ‘today’s the day, I identify as a pilot, bought a helicopter.’ Hell I can’t tell a man what to do in his own property,” [neighbor John Aubery] said.

Mozart in the Jungle TV show

Friends who are connected to the classical music world kept telling me to watch Mozart in the Jungle on Amazon Prime. So I did…

The show is interesting because the actors are portraying highly technical activities, e.g., conducting a symphony orchestra or playing a violin. They have to do this in time to actual music and the result is remarkably convincing.

The show starts when the president of the “New York Symphony”, played by Bernadette Peters (70!), brings in a young Mexican conductor modeled after Gustavo Dudamel. (We later get the backstory on the character played by Peters: she is a billionaire who made her fortune by marrying and divorcing four different men, not an entirely realistic outcome based on current New York family law, especially given New York’s vague cap on child support profits in the single-digit $millions.)

The highlights of the show include cameo appearances by real-world classical music stars, such as Joshua Bell, Emanuel Ax, and Lang Lang. If you’re a fan of Broadway-for-4-year-olds, you’ll also enjoy seeing Melody Yang.

One interesting aspect of the show is that its production straddles the point at which female victimhood began to dominate American public discourse.

  • Early seasons: Old man conducts and is replaced by young man. Attractive female cellist has sex with old male conductor. There is no discussion of the gender ID of any composer, but all pieces played are by male composers (including a modern commission).
  • Final shows, aired 4.5 months after Hollywood producer shower habits made the New York Times: Young woman conducts. Attractive female cellist has sex with other women. All pieces played are by female composers (and works by male composers are specifically excluded from a new orchestra’s mission). Characters speak statistics to each other regarding the percentage of conductors who are female.

I’m wondering if this could be used as an example of men becoming “woke”. The producers of the show are all described on Wikipedia with male pronouns. They could easily have picked a young female Latin American conductor to start off the show (e.g., modeled after Alondra de la Parra). There was no need for them to portray young female orchestra members as seeking to have sex with old male conductors. The show thus gratuitously reinforced gender stereotypes in classical music. No lesbian relationships were depicted, thus reinforcing heteronormative stereotypes for women.

By the last season, however, they were devoting about 30 percent of the dialog to decrying the lack of social justice for women conductors, women composers, etc. That shows an “unwoke” to “woke” transition?

Readers: If you’ve seen this show, what did you think?

Teenage Cocktail movie proves that “and they’re gay” is to plots as “in bed” is to fortunes?

The standard method for improving the messages inside fortune cookies is to add “in bed”. Examples:

  • “A friend asks only for your time not your money in bed.”
  • “A dream you have will come true in bed.

The movie Teenage Cocktail bubbled to the top of the Rotten Tomatoes “what’s streaming now” list with a 100 percent rating (our of only 5 professional reviews so perhaps that makes it easier to hit the top of the chart?).

The plot: two teenage girls want to earn money so they (a) sell their appearance on a webcam to a male audience, and (b) have sex with a man in exchange for cash. Unless we think that this is a new idea, why would critics like the movie so much? One theory: the writers added “and they’re gay”.

Would this work for recycling almost any other standard plot? Simply make the characters gay and the critics will be positive?

Readers: The movie is free on Netflix. If you’ve watched it, what do you think accounts for the 100% rating with critics?

Could the latest autopilots with envelope protection turn a deathtrap into a safe airplane?

I noticed a Mitsubishi MU-2 on the ramp at our local airport the other day. The twin turboprop airplane is famous for having unforgiving stall characteristics. The designers put in a stick shaker, as on many jets of the day, but not the stick pusher that is now common. Considering their near-jet level of performance, these airplanes have been considerably devalued by the accident history and perceived lack of safety (see Controller for what is currently available on the market; it looks as though a decent Solitaire can be purchased for $500,000. That’s for an airplane that can cruise at 310 knots, handle some ice (legally anyway; the practical ice capability is an open question), take 6 people more than 1000 nautical miles in pressurized comfort, fly over most weather at 33,500′, etc.).

More than 700 of these airplanes were built and a lot of them are still flying.

What if the latest retrofit autopilots could make the MU-2 a lot safer? Consider the Garmin GFC 600 and similar. These retrofit autopilots, even when not engaged, can provide “envelope protection” and nudge the flight controls in a safe direction if they sense that the plane is approaching a stall. It isn’t quite the level of idiot-proofing of an Airbus A320, but maybe if set to “max” could turn what has been “kind of unsafe” into “reasonably safe”?

Pilot readers: What do you think?

[More radical idea, but perhaps not for an airframe worth as little as $200,000 in airworthy condition: retrofit fly-by-wire controls. Put a big “don’t touch this” sign on the yoke of a legacy jet or turbopop and install a sidestick that, as in an Airbus or F-22, gives suggestions to the computer. Through extra-beefy servo motors, the computer becomes the sole manipulator of the flight controls. If the computer fails, the pilot can grab the yoke and look for a runway at least 10,000′ long (let’s presume he or she will be rusty!).]
