I assume that picture was meant to be a German V-1 flying bomb? Those were pulse jet engines, but not pulse detonation engines. They used the expanding gas of repeated combustion reactions, they didn't cause fuel to detonate.
I was apparently mistaken about there not having ever been a PDE powered flight
From France to London in the mid 1940s - get a grip before trying to lecture others who are not entirely keyboard jockeys.
Do you have any more information? I can't find any references to a successful PDE powered flight outside of the work being done by the Air Force Research Laboratory and Innovative Scientific Solutions, Inc.
Sorry, I'm not an engineer. I've worked in a fireworks factory and made my own model rockets, but I'm not a professional.
And no, I was thinking something like Galinstan, and not for propulsion, but for a power station.
But the way forward is clear. Make internet surveillance legal, and a free and open society will blossom, untroubled by questions of legality
As far as the difference between deflagration and detonation, you may find this helpful:
Why do I say it's hoped that they will replace scramjets? Because aerospace and military engineers are spending millions of dollars working on trying to engineer them as a replacement for scramjets and hoping they succeed:
I was apparently mistaken about there not having ever been a PDE powered flight... looks like researchers flew one for 10 seconds at an altitude of 100 feet with engines that create detonations at a frequency of 80 Hz.
I imagine a power station that could harness the power of nitroglycerin. Nitro is cheap as hell to make and releases incredible power... I'd love to try and build a plant that's buried deep in bracing rock and uses a very dense inert metallic alloy as a hydraulic fluid to harness the incredible power of cheap organic explosives.
I've talked to an accountant about this and we're both convinced this was an RCMP sting. They announced there was a vulnerability on their website about six hours before they patched it. That's either totally stupid and insane, or it was a police sting and they were just waiting to see who would be stupid enough to try and break in through the open door. Please have a seat.
Due to the way MS products are licensed, and the cost of training, and the fact that the average person gets confused easily with software, it is cheaper for large organizations to buy the MS products for use by the minority of users that actually need it.
I am sitting in a $890 chair right now. any good company will do it. I'm thinking you haven't priced real office furniture as the standard desk I am at is $2300 and it's a no frills Steelcase.
Am I missing something here or are you ignoring how diesel engines work? To me at least it looks like a series of small explosions.
You're missing something. Diesel engines are internal combustion engines.
It's probably best to accept that some people won't accept your proposed terminology and move on to discuss more than just semantics.
That's why I posted...
Likewise, worker bee machines that are pretty much dumb terminals are not going to use SSD. But other machines that people actually do and store work on, that may be something different.
Look, tape is on the order of penny per gigabyte. Hard disks are somewhere between 5-10 cents a gigabyte. SSD is about 50 cents a gigabyte. Many people still back up onto hard disk even though tape is more reliable. We are going to use SSD because there are benefits that justify the order of magnitude increase.
Why do you need a stitting and a standing desk? just get an engineers or draftsman chair and sit at standing level when you need to.
Or go all out and buy the power up/down desks. I prefer the tall stool chair that way I can change it up as I need.
There is zero real proof of this. Where is the 20 year study comparing the office workers to the shop workers? This is as bad as all those GNC studies on how their products make me healthier.
So sleeping under and overpass or in the park is better for them... How honorable you are to support keeping people from at least having a roof over their head.
CM is there for both preventing fuck ups and dealing with them when they occur. First things first: do you have a test environment? If not, build one. Do you have documented processes? If not, document them.
Proper change management ensures that: 1. people in the group know what is going on. 2. you have a second/third set of eyes to ensure that you have both a plan, a backout plan (or plan B in case it can't be backed out) and a test methodology to ensure that a change hasn't broken things. 3. to make you think about the implications of what you are doing, and 4. that business stakeholders are informed and know how to plan around any impact both expected and unforeseen.
If you aren't doing all of those things already, sorry dude but you are just winging it. That's efficient, etc. until one day it all goes horribly wrong and you need to figure it out on the fly how to get back to normality, with unpredictable outage durations, etc. All of that should be worked out before going live with your changes.
Yes, it sounds like a lot of faffing about for no real benefit, but really, one day it will save your arse. And really, you will be surprised at just how many effects even a single change to a production system can have.
