re: Colonial pipeline hacked? - timdallinger
[quote]You mean walking out and writing things down? How barbaric![/quote] It's not even that complicated. In the control center, there is a SCADA system that tracks pressure, flow, temperature across the whole network. Wherever there's a sensor, there's a measurement transmitted to the control cen...

re: Colonial pipeline hacked? - timdallinger
The control system wasn't hacked. That's usually on a closed loop intranet. This is how the pipeline is controlled and the safety systems implemented. The company business side was where the breach occurred. Their billing and scheduling software is down. However, at each delivery location, th...

re: Colonial Pipeline Ransom In The $100’s of billions. - timdallinger
[quote]It's a fricking pipeline, shite runs through it. If it can't be operated somewhat manually, heads need to roll.[/quote] All pipelines are run remotely by a control center. Someone is watching a computer screen 24 hours a day, monitoring pressures and flows. There's also a mass balance leak det...

re: Old, but very affective way this country can be "United" again. WAR, (over there). - timdallinger
It's important that oil still be priced in USD; the petro-dollar. Despite what current culture says, traditional energy still runs the world. That's why the dollar remains the international exchange currency. If Saudi moves to the petro-yuan or petro-ruble, the dollar immediately loses all backi...

[quote]I have no sympathy for them, not when you consider the number of people these hedge funds have financially injured.[/quote] The main benefactors of the gamma squeeze were institutions. IE hedge funds. Yes, several blew up. But more made an absolute killing. WallStreetBets think they move...

re: Can someone explain this Gamestop stuff to me like I’m a teenaged Maxine Waters? - timdallinger
There has been some good explanations but incomplete. 70% of GME is institutional ownership. That means funds hold the common stock. Blackrock alone owned 17%, although I assume they've trimmed their positions through this rally. In any stock there are essentially investors betting on it to ri...

re: Why should regular people - timdallinger
Yes, some funds were short and lost a ton of money. Others were long. 70% of Gamestop was institutionally owned. 13% of Gamestop (GME) common was owned by Blackrock alone. The media is portraying this as a strike against the Wallstreet elite. That's embarrassingly incomplete. It's unclear whether...

re: Has anyone else here ever created Water Hammer? - timdallinger
If you've ever shut off a faucet, especially in the basement of an older house, and heard the pipes rattle or knock, that's the same phenomenon. Fluid is traveling through a pipe. It has momentum. When a valve closes, the flow energy is converted to pressure. The pressure wave travels back upstre...

re: Best way to bring a cast iron skillet back to life - timdallinger
Post a pic and I can tell you what I would use for the particular piece. If it's rusty, soak in vinegar (acetic acid) to break the iron oxide bond. I don't leave it in a vinegar bath for more than a few hours because the vinegar can eat the iron too. If it's carbon build-up, I use water and ...

re: Cast Iron Restoration Question ... - timdallinger
Vinegar works well for rust. Acetic acid breaks the iron oxide bond. It's not as effective for carbon build-up. Electrolysis takes care of both. I use lye bath and then short vinegar soak depending on how bad of shape the piece starts in. ...

re: Cast Iron Restoration Question ... - timdallinger
To echo Bob... I use lye exclusively. I don't measure the lye anymore. I generally do a few pieces at a time now so it's a large Rubbermaid tub. About half the lye container. Pour into water carefully! Use gloves handling until you've rinsed the lye off well. A week usually does the trick....
