Max Cooper - Repetition (video by Kevin McGloughlin)

The Worst Typo I Ever Made

StukaFox says...

The worst DevOps mistake I ever made:

Assignment: On ~1,000 -physical- RHEL systems, change the default run level from command line to GUI (don't ask).

Solution: Hey, all our config files are controlled by Puppet, so this'll be easy!

(If you don't know what Puppet does, it enforces file configurations, so if you change a single file on the Puppetmaster, that change is pushed out to all servers running Puppet)

Ok, all I need to do it edit a single file, change a single number in said file and issue a single command: reboot. Easy-fuckin'-peasy.

The file I need to change is /etc/inittab -- this file tells a Linux system which "run level" it should initiate upon booting up. runlevel 3 is command line and runlevel 5 is a GUI like Gnome or some other tragic perversion of the whole reason you run Linux in the first place. All I had to do was change from runlevel 3 to runlevel 5. And reboot.

So simple; so stupidly simple.

So stupidly simple at 3:00am. When I hadn't slept all night. On a production network. When I'm working from home away from the office. On a Saturday when no one is in said office.

I make my change and save it, then push it to the version control system. Puppet picks it up and pushes the change to ~1,000 physical computers.

Done and done!

Remember I mentioned that I had to change a single file AND execute a single command: reboot?

Here's where things go tragically wrong.

My changes worked PERFECTLY. Everything did exactly what I told it to: Puppet changed the file, and rebooted the servers.

Only they keep rebooting. They keep rebooting over and over and over and over. I can't access any server on the network. Worse, while I'm trying to figure out WTF I did wrong, the 30 minute time-out I'd set on our alerting system, Nagios, expires.

Did I mention that I pushed this change to ~1,000 servers? ~1,000 servers that won't stop rebooting and aren't reporting into Nagios, thus being marked as down?

At 3:31am, on Saturday morning, the pages to ALL the on-call engineers began. One page per engineer per machine. About one every two seconds. And I'm getting paged, too -- except some of the pages are Nagios and some are utterly irate engineers who want to know exactly WTF is going on and I can't tell which is which because I'm getting text-spammed like crazy.

And those servers? They just keep right on rebooting.

At that point, I felt the kind of existential dread that only people who work in IT know -- the kind of dread that arises a picosecond after you've hit ENTER and realized you've type 'rm -rf /' or some-such -- because I knew at that very second exactly what I'd done wrong.

I'd typo'd "5" and made it "6" in the runlevel. And pushed it to ~1,000 -physical- servers. And then rebooted them ALL.

"So," you're asking, "Whyfor is runlevel 6 a big deal?"

Because of this:

runlevel 3: command line.
runlevel 5: GUI
runlevel 6: REBOOT THE FUCKING COMPUTER.

What I'd done was told every production server on our network to reboot as soon as it rebooted, which leads to another reboot, which leads to another reboot, lather rinse repeat.

At 3:45am on Saturday morning, I knew that every person in IT would have to drive into the office, visit every production server with a bootable USB key, change the BIOS to boot off the key, boot the server into Single User Mode, change the damned file by hand, then reboot the server. This takes about 10 minutes per server -- times ~1,000.

I learned a number of valuable lessons that day:

1. DOUBLE CHECK YOUR FUCKING WORK.
2. See lesson #1
addendum: filing for unemployment insurance in Washington state is amazingly easy.

And that was the very last time I ever worked on physical hardware. To this day, if it's not in the cloud, I ain't fucking touching it.

Here endth the lesson.

Lawyer's Reaction to Carnage at Lafayette Square

BSR says...

I'm sure this guy has a lot good things to say but I can't handle the constant zoom in and zoom out after just about every friggin' sentence he speaks. It's like a cameraman trying to validate his own existence. Very annoying. I'd rather read the text version if there is one.

Trump Has SS Attack Peaceful Protestors For Photo Op

newtboy says...

Sorry comrade, all true, on video. It's you who is repeating lies and pure bull shit, and complete contradiction of what dozens of news groups including Fox reported from the scene...even contradicting the Whitehouse itself. I expect nothing less from delusional, sycophantic, morons who prefer to believe convicted racists and repeatedly convicted con men like Trump over literally hundreds of videos and thousands of eye witnesses, including clergy, Australian and other non American reporters, and the words of Trump/Barr themselves who publicly admitted it.
What, are you saying Trump is lying, he didn't decide on a whim, without asking the church leadership and against the suggestions of his SS, to go take pictures, he really did know the protesters were there and pushed some violent law and order on them and really wasn't an unbelievably ignorant buffoon who didn't notice the protests on his front door all week like he claimed yesterday, and didn't have Barr direct the violent removal of protesters by force, without warning, and well before curfew...for picture time? They said it, not CNN.

No other president has ever been so self centered as to direct the SS to attack peaceful citizens with grenades, rubber bullets, irritant smoke (so you don't dishonestly claim no teargas because you disagree with the long time accepted definition of the words, but irritant smoke is teargas), clubs, boots, hooves, pepper balls, and shields so he could use a church he just attacked as a photo prop. Never.
They even attacked the priests from the church he used for his 2 minute photo op as they were tending to injured protesters on the church porch, removing them violently by force, taking moronic photos with the church and bible as props not sacred sights and texts, political propaganda photos and campaign commercial videos that have been denounced by most religious leaders before running back home surrounded by hundreds of guards like the tantrum throwing scared little baby he is.
But I'm certain you will say he's the most conciliatory, thoughtful, empathetic, leader who has brought the country together like never before and made it incredibly prosperous, any contradiction therefore must be fake news, not reality any non cult member can see with their own eyes. Jim Jones had followers like you. Go have some Kool Aid, why dontcha.

Funny, if he's pushing law and order against rioters and looters, why is he directing attacks against peaceful protesters (they now claim the protesters were throwing rocks, but oddly have no footage of it)...more importantly, why isn't he going after the boogaloos, a right wing, pro Trump, anti liberal, pro civil war, pro collapse of society group who has been seen at every riot even though they're 100% against BLM since they're also a white power group...caught in Vegas preparing to bomb crowds after their plan to start riots fell through.

Can you name instances of Antifa being caught doing the same? I'll answer for you since I know you'll just go silent, no you can't.

Again, dummy, they weren't rioting or looting a thing, purely peaceful protests at the Whitehouse until Barr ordered their removal by force. Thousands of cameras, not one showing riots or looting, only showing the SS stormtroopers tossing grenades into crowds and shooting rubber and pepper bullets point blank in the face.
Completely wrong....comrade. No other president in our country has ever been so disrespectfully divisive as to insist the streets belong to him and then take them by force during nation wide, actually world wide protests over police violence, actually telling police to become more violent. None.

Pure Bull Shit.

POTUS pushing law and order against rioters and looters. How wrong.

Joe Biden response towards Tara Reade allegations

JiggaJonson says...

Just fyi

The supposed sexual assault happeend in the middle of 1993 https://www.nytimes.com/2020/04/12/us/politics/joe-biden-tara-reade-sexual-assault-complaint.html

Isn't it a bit odd that the person who passed the Violence Against Women Act in 1994 (so he was lobbying to get it passed and the bill was introduced in January 1993), am I the only person who thinks its odd that he passed this bill:
https://en.wikipedia.org/wiki/Violence_Against_Women_Act
see also https://www.congress.gov/bill/103rd-congress/senate-bill/11 for the full text

So you mean to tell me
While he was co-sponsoring/writing/passing THAT PARTICULAR LAW that created the following:

--- established annual $1.6 billion toward investigation and prosecution of violent crimes against women

---codified sex crimes to make them Federal crimes

---imposed automatic and mandatory penalties on those convicted

---allowed civil cases to be brought in cases prosecutors chose to leave un-prosecuted

---created confidentiality protections for victims

---created a training program for judges to encourage them to prosecute sexual assault crimes against women


So WHILE he's making it easier to sue and bring charges against former employers and creates mandatory minimums for those found guilty and if the prosecutors don't want to do it, created a pathway for civil lawsuits to be brought - you're telling me that WHILE he's doing that, he sexually assaults one of his employees from his offices WHILE he's doing that?

That doesn't make any fucking sense.
That doesn't make any fucking sense.
That doesn't make any fucking sense.
That doesn't make any fucking sense.
That doesn't make any fucking sense.
That doesn't make any fucking sense.


That the best you got you little bitch?

Why You Can't Name A File CON In Windows

Every Covid-19 Commercial is Exactly the Same

TheFreak says...

A crisis! What a great brand opportunity!

An example of how corporations are like sociopaths. If a person stood up and gave a speech taken from the text of these ads, you'd be wondering what the fuck's wrong with this person for making the whole thing about themself. You'd also be wondering why broadcast news is carrying it live every day.

Why The Right Wing End Game Is Armageddon

newtboy says...

That depends on which bible you mean....there are many.

Really? Lost to history?! Hardly....lost to the ignorant and uneducated maybe, but even atheists like me know full well Jesus the man was a Jew, and definitely not a European or "white". Roman/Italian artists knew this, but worked for a Roman church so portrayed him in their image.

Genetic purity?! Lol. I guess that means no one has EVER become Jewish, you're either born one by two pure Jewish parents or not. Hardly reality, and would reject nearly every person in Israel (or elsewhere). Just because there is a long standing religious/cultural taboo against marriage outside the culture, it still happens, as does conversion. Racial/genetic purity is a fallacy debunked by genetic testing.

Prophecy is a leap. No prophecy has been correctly interpreted until AFTER the events supposedly prophesied occurred. It's ridiculous to go back after the fact and claim "see, now that I know exactly how to interpret the unclear prophecy I couldn't decipher before, it's a 100% perfect prediction" but never be able to predict the future. That's the same nonsensical logic mediums use.

The second temple was also the third, since the true second temple was originally a rather modest structure constructed by a number of Jewish exile groups returning to the Levant from Babylon under the Achaemenid-appointed governor Zerubbabel. However, during the reign of Herod the Great, the Second Temple was completely refurbished, and the original structure was totally overhauled into the large and magnificent edifices and facades that are more recognizable. Logically, the third temple was the one destroyed by Romans, the second replaced by Herod but the new one was still called the second temple anyway. (To avoid contradicting prophecy? ;-) )

If the dome of the rock, the second most holy place in Islam, is destroyed, expect Jerusalem to follow soon after, as that will definitely start a religious war between nuclear powers.

Herodotus is credited with using the term Palestinian first, in the 5th century BCE as an ethnonym, making no distinction between Arabs, Jews, or other cultures inhabiting of the area. Romans adopted the term as the official administrative name for the region in the 2nd century CE, "Palestine" as a stand-alone term then came into widespread use, printed on coins, in inscriptions and even in rabbinic texts.

I think you are confused about the history, here's a primer...
https://en.m.wikipedia.org/wiki/History_of_the_Jews_and_Judaism_in_the_Land_of_Israel

The area was populated by various people's including Jews until the Jewish–Roman wars of 66–136 CE, during which the Romans expelled most of the Jews from the area (well, really they arguably left voluntarily because they refused to be second class citizens barred from practicing their religion freely) and replaced it with the Roman province of Syria Palaestina, the Arabs were already there, not invaders or immigrants. When Assyrians (Mesopotamians) invaded in circa 722 BCE, they ruled empirically, meaning only the Jewish ruling elite left, returning in 538 BCE under Cyrus the Great....so no, the Arabs didn't just settle after the Jews were dispersed.

It's patently ridiculous to say the Arab nations were unprovoked, Jewish illegal immigration led to a hostile takeover of the region by illegal immigrants with rapid expansion of their territories into their neighbors continuing through today. The Jews defeated the Arabs thanks to American backing and exponentially better hardware. It was only their right if might makes right, and the Arab nations are under no obligation to let them keep what they stole any more than the Jews were obligated to let the Arab nations retain control in the first place. If Iran, Syria, Iraq, Saudi Arabia, or any combination can take it, by your logic they have every right to do so.

I do agree, in the end there will be more conflict until the area becomes uninhabitable....largely because every religion's prophecies end with them in control, and no one wants to admit it's all nonsensical iron age tribalism at work.

Plus, the YT timeline covered text at times. Makes me feel like I missed that one important clue that would have made everything come together for me.

Now I'll just watch it again without stopping.

It took me a while to watch too, I had to keep pausing because the writing went past a bit quickly.
