redis_mlc··on Daniel Ellsberg: The 90-year-old whistleblower tempting prosecution
If you want to learn more, just watch the movie Dr. Strangelove. It was marketed as a comedy, but people in the know consider it to be non-fiction:

https://en.wikipedia.org/wiki/Dr._Strangelove

General MacArthur was dismissed during the Korean War because the White House weren't sure if he was going to use nukes or not (like the movie.) The policy was that the US was ready (bombers with nukes were positioned in Japan), but President Truman wanted to give final advance approval to commanders, yet MacArthur was issuing his own policy.

https://en.wikipedia.org/wiki/Douglas_MacArthur

(It turns out that MacArthur was right about basically everything he ever said, and continued to advise Presidents.)

redis_mlc··on Real-time Netlisting in KiCad [video]
1) Eagle Premium is a $495/year AutoDesk subscription. (There's a Standard version for $100/year for small boards.)

2) Both Altium and Eagle have nice component libraries, which KiCad has a lot of work to improve.

redis_mlc··on US ‘Gets Its Ass Handed to It’ in Wargames: Here’s a $24B Fix
The only institution that can field an army is the government - it's not something that happens organically or can be trusted to private companies.

Same with the State Department, FEMA, regulations, etc.

Having said that, neither Republicans or Democrats want small government. But the Biden administration is like a crack addict when it comes to deficits - they're destabilizing our currency.

redis_mlc··on Naomi Osaka faces default from Grand Slam for refusing to speak to media
I wanted to add some background so HN commenters can appreciate what Osaka is trying to say, instead of sputtering "but she signed a contract. QED!"

I know a few high-level female musicians.

Most of them have nearly crippling anxiety they face daily if they look at social comments, which spikes near a performance. (Think "ball up in the corner in a fetal position.")

Youtube and Instagram have enabled them to have studio careers, but often they don't/won't tour.

The idea of continual interviews, especially after losses, is beyond comprehension for many people. I was alarmed when I saw that Osaka had 134 losses - even a fraction of interviews covering those losses would destroy many egos.

redis_mlc··on Amazon refused to refund $7k after shipping an empty box instead of a Sony A1
+1 BH. I've ordered entire palettes of camera gear, and every filter and end cap was accounted for.
redis_mlc··on Ask HN: Did preparing for LeetCode type of interviews improve your skills?
As of 2020, most SV interviews for Devops/SRE were not Leetcode - just normal programming, though possibly kinda lengthy.

In 2021, it's a few percent higher. The one I saw recently was related to checking for N matches against M permutations.

All required passing a test suite.

redis_mlc··on How I raised a $5.1M seed as a first-time, female, solo founder for a biotech co
To expand on this (for Non-YC situations):

1) VCs want to keep the door open for later by not outright saying "No.", since there's no incentive for them to do otherwise.

2) VCs follow the herd (need social proof), so they will often wait for that area to blow up, or wait for another VC will be the "lead."

3) VCs today would rather be late investors after the concept is proven and they can move hundreds of millions of dollars around to get even more hundreds of millions.

Also note that VCs like to imply that they have integrity, but that's often not true:

1) They've had meetings to collude against YC (documented in the press.)

2) Silver Lake Partners revokes employee shares if you leave before 4 years ("In it to win it.") (documented in the press.)

3) Shocking personal anecdotes.

redis_mlc··on The cost of cloud, a trillion dollar paradox
That was my observation as a DBA.

The most powerful tools we have are aggregated reports and data retention periods, the same since the 1970s.

Running 10 copies of the same report (but each one with slightly different bugs) across 34 PB of data for 10 different departments is absurd, yet here we are.

Specifically for Dropbox, they're not a retailer like Safeway with 10,000 products and 100's of locations to crunch product and shipping data for - Dropbox could use a single server for their entire digital products data warehouse.

(I operated a data warehouse myself (literally) at Yahoo - 10 servers generating canned web reports for 500 managers. I heard they replaced it with a 1,000 node Hadoop cluster later.)

redis_mlc··on The cost of cloud, a trillion dollar paradox
> things like this: https://aws.amazon.com/solutions/case-studies/dropbox-s3/

Yeah but why do they have 34 PB of analytics data?

redis_mlc··on Microsoft president: Orwell’s 1984 could happen in 2024
Just so people have a ready response for Schmidt's thoughtless statement:

1) I don't want potentially naked fotos or conversations of my family online. Do you?

2) Regulations and customs change over time. Something ok 10 years ago can be damning tomorrow.

3) How do you maintain privacy of medical and lawyer conversations when anything can be released without permission?

Ironically, I had the same conversation with a lawyer ("I have nothing to hide.") who had teenage daughters. It really didn't sink in until I gave him those examples.

redis_mlc··on The downfall of Malaysia’s biggest sugar daddy platform
It's an amusing article - combining Islam with Sugarbook is pretty explosive. (Malaysia's dominant ethnic groups are locals, Indians and Chinese, but their constitution favors Muslims.)

It's accepted to have temporary wives (under a religious marriage for a few days) as escorts in Islamic countries, but quietly. Once it hits the press, authorities often feel compelled to do something about it.

But Sugarbook doesn't even fall under the fig leaf of temporary wives, and the membership numbers are shocking for a small country.

Some other commenters asked what's the harm of Sugarbook or OF:

1) women have a limited window to start a family and have children. Disrupting that has a very high price for both individuals and society.

2) making relationships purely transactional

3) normalizing the above across the population.

redis_mlc··on I Was Robbed in San Francisco While the Cameras Rolled
I live in SF, and the comments you've seen on HN are accurate.

It's not Somalia, but there's always the potential for escalation to violence on the street, in stores and near ATMs - I've seen it.

I wouldn't allow any of my family to walk alone anywhere.

redis_mlc··on San Francisco’s Shoplifting Surge
If you watch the video to the end, you see how it escalates from shoplifting to violence when the thief doesn't get his way - essentially he doesn't know the word "respect" beyond "I demand you respect me", even in the midst of a robbery.

Having seen similar shoplifting incidents around SF, I feel bad for the security guards. They're not allowed to physically stop thieves at larger chains, but they're expected to follow and hinder them. It's a very tough job, ad prone to injury.

It's fascinating to watch the change in behavior when the "security guard" flashes his SF Police badge and says, "Actually, I'm a real cop." Then the thief drops everything, stops mouthing off, and heads for the door..

redis_mlc··on “Miss Shilling's Orifice” helped win the war (2020)
All sides in WW2 captured airplanes and had dedicated technical staff to evaluate them.

Here's an interview with a German ace who evaluated several Allied planes (he preferred the P-51):

https://www.historynet.com/aviation-history-interview-with-w...

Britain mostly was on the lookout for fighters and fighter/bombers with novel antennas, since they could be used to understand new radio navigation and radar electronics. (One of the most advanced landed near shore, but the Navy guarded it in salt water instead of handing it over for timely study.)

During the Korean War after a MiG-15 was "donated", the issue was how to verify it wasn't booby-trapped before entering it, since test pilots are valuable (Chuck Yeager was one of them.)

https://en.wikipedia.org/wiki/Operation_Moolah

At the end of the Vietnam War, the north captured an entire fleet of US aircraft (87 F-5s, plus more types) that were used successfully against air battles with China.

redis_mlc··on Civilization Is Older Than We Thought
The North Sea was Doggerland 8500 years ago:

https://en.wikipedia.org/wiki/Doggerland

You could walk from the Netherlands to Britain.

Before that, the Mediterranean Sea was a dry depression. When the Atlantic barrier collapsed, you can imagine the wall of water filling the basin and chasing early humans uphill.

redis_mlc··on Bonkers tri-wing jumbo jet concept reduces fuel consumption by 70%
I study aerodynamics, so some comments:

- vertically-stacked wings (biplanes, triplanes) are common, but I've never seen 3 non-stacked wings. Not even the Nazis were doing that, which is a red flag for this project actually.

(I think it was France that passed a law that airplanes required at least 2 stacked wings around WW1, as monoplanes had too many structural failures at the time.)

- more wings mean more lift, but also more drag

- one advantage of more wings is that airports support only certain wing spans, so winglets or more wings is a work-around for that. (The result of winglets is mainly to effectively lengthen wing span.)

- very thin wings aid in penetrating the sound barier. This is a subsonic plane in terms of speed, but more accurately it's a transsonic plane (mixed subsonic and supersonic) over certain parts.

- I don't see the second engine, but if it has two, that's adequate for most oceanic operations because other small jets are allowed to do that, and ETOPS. (If ETOPS regulations apply, then engine reliability history is examined.)

- If the engines are too close together, then an uncontained engine explosion can destroy the other. This is fairly common for engines mounted near each other.)

redis_mlc··on You Can’t Sacrifice Partition Tolerance (2010)
> If you have a lot of money and are willing and able to build a private network with enough redundancy

Google has done this. Possibly AT&T also.

> Notice who the author is: Eric Brewer

Note that Professor Brewer is a teacher/academic, and CAP is intended for instructional purposes.

As a DBA, I find CAP totally inadequate for any business purpose.

Try explaining to a business owner, "Yeah, when our network partitioned, we couldn't accept purchases in both partitions." Their response will be, "So all that money you spent on HA was really based on a lie?"

redis_mlc··on Out of Memory Error – The RAM Shortage of 1988 (2016)
I remember this - it was a big deal, similar to the GPU shortages.

I won a PC RAM expansion card at a VAR event, and it took months for them to scrape up enough memory to populate it.

(It ended up running too hot for my tastes, so I took it out.)

redis_mlc··on Greyhound Canada shutting down all bus service permanently
Greyhound buses in Ontario and Quebec were like the Twin Otters in Alaska.

It's a huge loss for smaller and northern communities. Besides affordable, scheduled passenger service, Greyhound carried film reels for theaters, and likely other materials.

Really it was an essential service - I don't see how many rural towns will continue to be viable. Certainly young people will leave for the big city and never return.

Note that if Greyhound still owns their city-center terminals, those could be worth a billion dollars.

redis_mlc··on Perverse Downstream Consequences of Debunking
Actually, no.

Virtually everything the leftist media has printed in the past 4 years has been shown to be false:

- WaPo admitted Trump's phone call conversation to an election official was faked (used in the second impeachment)

- Twitter has admitted they shouldn't have suppressed the Hunter Biden stories

- fact-checking by many social media sites has been outsourced to interested parties, often controlled by the Dem party or CCP

- there was no insurrection, since the 5 people who died were not killed by rioters, were mostly let into the Capitol by police, and didn't have guns.

I could go on, but it turns out the left/Dems are outright daily liars.

redis_mlc··on Remains of nine Neanderthals found in cave south of Rome
> whatever the reason

Both Iceland and Italy have had multiple serious eruptions that could have wrapped around 2 or more winters in Europe and N. Africa, starving almost everybody.

I once read that our mitochondria indicates the human population was down to 5,000 at one time.

Here's one article mentioning the Toba explosion 70,000 years ago and blocking the sun for 6 years. There's still a Lake Toba:

redis_mlc··on Philips LEDs from Dubai: The Royal Lights You Can’t Buy
I read an interview with the Luxottica founder - he's an absolute bastard, and proud of it, like a Bond villain. We'll have to wait until he dies to break that monopoly up.

When you visit an eyeglass store in the US, it's likely all Luxottica frames, especially the chains they own:

redis_mlc··on Child's burial 78k years ago in Kenya was a Homo sapiens milestone
I was going to say that.

We can see the Great Wall of China from space.

And we can also see beaver dams from space.

(Note the Great Wall was built for a mundane reason - the Han people couldn't defeat the Mongols on horseback, but they could keep building walls until the horses could no longer enter. Byzantium/Constantinople also adopted that strategy, which worked for over 1,000 years until the Ottomans built the world's largest cannon and blasted holes in it.)

redis_mlc··on California population declines for first time in more than a century
It's not fire-related:

- state income tax

- real estate prices

- threatened wealth tax and pursuit across state lines

- family court system heavily stacked against men

- policing and homeless issues in major cities

- water supply issues (half of proposed projects stalled for decades.)

It should be interesting to see how big the hole is in the state budgets over the next few years - could be breath-taking.

redis_mlc··on How college became a ruthless competition divorced from learning
The above un-informed screed is amusing, since it illustrates how the left thinks they know what they're talking about and what's best for others, when they have no clue.

>> he doesn't move in the same social circles as those elites > That's just untrue.

It is true - Trump never was a New York A-lister or B-lister. He could move in business circles, but not social ones.

> they will keep drawing the wrong conclusions about what to do.

His supporters wanted a wall, and he started construction on it.

Harris is supposed to be the immigration czar, yet she's afraid to be photographed near the border, because there's no wall.

The CCP engaged in trade violations, and he addressed that with tariffs.

Sounds like the right conclusions to me, even obvious.

> Trump supporters don't like reality as it is

His supporters like that he was willing to be their voice against the establishment in competing globally in the job market against illegal aliens, instead of being dismissed by the left as "deplorables."

> you never need to switch jobs

For most people, especially as they get older, there is no option for switching jobs - either you get on long-term disability or you're homeless. This one phrase proves how out of touch you are with reality.

Sometimes people don't appreciate what they have until it's gone.

The Democratic party and White House staff are infested with CCP lobbyists, including Biden's family and his Chief of Staff. Since the CCP has been in a cold war with the US since the 1950s, I hope it turns out well, but Trump/Pompeo had a clear strategy, and Biden doesn't.

As an illustration of what the CCP wants, consider rare earths or 5G. China has world-wide monopolies on those - but their goal is world-wide monopolies on everything, regardless of dumping rules.

Trump was the best and most productive US President in the past 75 years. Shame on the left for two baseless impeachments that prevented our leader from even accomplishing more.

You should know what you're talking about before posting screeds on HN. But then I could say the same thing about most of the left - it would be nice to have paradise on earth, but Marxism doesn't get you there.

redis_mlc··on Astronauts with disabilities can apply to Europe's space agency for first time
Well, the full story is ...

The vast majority of pilot applicants don't really need to be concerned with their vision:

- civil: will pass the vision requirements with correction to 20/20 near (the instrument panel) and far with glasses, contacts or surgery.

- US military: last time I checked, one service allows laser surgery, and the others are evaluating it.

I don't recommend eye surgery for civil pilots because of the risk of infection, sparkling, regulatory changes and changes in eye geometry in middle-age.

Note that DUIs and epilepsy are disqualifying, and heart problems usually make things difficult.

- Islam doesn't permit voluntary suicide, but there are rewards for funding or committing violence to advance Islam. He could have rationalized the latter.

redis_mlc··on Bill and Melinda gates divorce after 27 years of marriage
No, he meant that women create a narrative that makes them look good in divorces that is often the opposite of the facts.

So women will say (and subconsciously think and believe) that breaking up the family is good for the children, when nobody else would agree, so that her decision looks good.

Hence the 50% divorce rate with 70% of those initiated by women - they set aside the effects on children.

“I Put The Kids First.”

You can read a similar example in this quote by Hillary Clinton:

https://therationalmale.com/2015/09/02/solipsism-i/

Obviously the primary victims of war are the combatants, mostly men, but that doesn't fit her narrative, so she makes up nonsense and no doubt believes it, even though she has legal training.
