storage really isnt an issue. H2 isnt any more dangerous than LPG, petrol or kerosene. Ironically a slow leak will be safer with H2 than LPG, doesnt produce toxic smoke, isnt as "hot" as a gas flame. There are benefits.

Brit MPs pour cold water on hydrogen as mass replacement for fossil fuels
there isnt a mass market for H2 hence green sources H2 isnt worth it. Once there is a market then countries with excess green electricity will start to look at cracking water as a money source. There are quite a few countries that could make money from H2 production but without the demand it isnt worth the infrastructure.
FCEV is more than possible with current tech. https://wrightbus.com/en-gb/hydrogen-bus-streetdeck-hydrolinerFCEV there's one right there. 8 mins of hydrogen filling for 200 miles+ these are early days of course but still possible. Newer fuel cells are also being developed.
EV arent bad but the charging times are horrific for mass transport. If entire cities converted all their ICE to EV then the grid would collapse in short order, those cities would brown out. H2 on the otherhand would not, people would go to filling stations, the same as ICE.

3. Fuck people who disagree with you. amirite?
4. Abolish HR so 3. doesnt get problematic. I dont think you thought of that cost saving measure.
5. I will happily clean up crap and kowtow to your whims.

Swatting suspects charged with subverting Ring doorbell cams and calling cops
Re: Seems kind of poetic
so you would find it hilarious if your wife and kids are woken at 2AM by a squad of armed police shouting and booting the door in? Not aure I find it hilarious.
What about if it was the neighbours house and the swat teams used your lawn, fence and back yard to go piling through?
Doesnt sound like fun to me. I assume you have never seen such an operation in effect. You might have a lot of bravado now but it isnt like the movies and is a lot more scary in real life. Especially if you have your own kids who are crying in terror.

Women sue Apple claiming AirTags helped their stalkers
Re: What's that?
air-tag = thing
thing sends out bluetooth beacons
iphone = gadget
gadget has an OS
OS has a function to listen for bluetooth beacons
when an airtag beacon is heard the gadget sends its location to the internet overlord masters
internet overlord masters can update owners of thing with the location given by gadget
if you too have a gadget then you get a notice if there are things around you that have been there for "an extended period of time" talking to the internet overlord masters

FTX disarray declared 'unprecedented' by exec who cleaned up after Enron
Re: "unprecedented"
which is the irony. Become a master criminal by running a successful company so badly that even though you make money, so did everyone else. have no accounting, no business plan. Then claim incompetence so your assets arent totally taken away. That being said if he has loads of offshore accounts everywhere then good luck finding them all.

Atlassian, Microsoft bugs on CISA’s must-patch list after exploitation spree
Re: Connected to ... what?
I will bite. How do you mean? I do know you can have exchange live behind ADFS and WAP, but these current exploits require an authenticated account anyway so would get past the WAP. The calls to exchange are quite valid remote powershell calls and use an exploit via normal channels.
How else do you mean for exchange to be able to send email externally and not be connected to the internet? How would you get OWA working for example?
We run hybrid AD and migrated onsite to offsite exchange, this needs an exchange server to operation (no mailboxes on the server, plus there is no route for onsite exchange OUT via SMTP either - only microsoft 365 IPs can connect IN via the firewall so its about as good as I can get it. I supposed I could also hamstring IIS too if necessary.
Stop us if you've heard this one before: Exchange Server zero-days actively exploited
Re: Side note on Exchange design
the core issue is that users can still invoke powershell remotely. They might not be allowed to do anything but it still starts the process, if there is an exploit in the process itself then this will instantly give you access as the process starts pre-authentication.
It is like unlocking your front door, letting the person into your house and THEN checking their ID hoping they dont know how to walk around you.
Re: I'm already using zero trust with Exchange
see this is a great approach till I read this:
https://learn.microsoft.com/en-us/powershell/exchange/control-remote-powershell-access-to-exchange-servers?view=exchange-ps
Especially THIS bit:
"By default, all user accounts have access to remote PowerShell. "
Wait what? It is qualified by:
"However, to actually use remote PowerShell to connect to an Exchange server, the user needs to be a member of a management role group, or be directly assigned a management role that enables the user to run Exchange cmdlets. "
Riiiight. So how about doing THIS instead:
USER->SERVER: Hi, I want to use powershell, totally not to pwn the server
SERVER->USER: credentials please.
USER->SERVER: No
SERVER->USER: .......
rather than
USER->SERVER: Hi, I want to use powershell, totally not to pwn the server
SERVER->USER: sure, here is powershell, please log in.
USER->SERVER: <sends exploit instead of powershell credentials>
And the fix? Surely you could set the default to deny and allow a select few? Nope! You cant set a default, you need to explicitly deny individual users! Insane.
We run hybrid so need an exchange server for management, however the exchange server is nicely locked away on its own subnet, external access is only granted from microsoft 365 IPs, not perfect but stops others knocking on the door.
