Obviously I would have forgotten most of this given the change was 20 years ago but IIRC DST config on Solaris at the time was statically coded. You could modify the timezone config as a hacky fix on Solaris 8 but the permanent fix involved recompiling zic.

I live in Western Australia. for 3 years we trialed DST from 2006 to 2009. It was a nightmare personally, I was a sysadmin at the time and enterprise management tools were expensive and crap so we had to roll out DST file changes across our fleet manually. And because the change to allow DST for our region was a rushed job we then had to roll back after the 3 year unsuccessful trial.

Honestly, it was super stressful at the time. And DST that doesn't exist doesn't bother you in the slightest. Every day ends and flows into the next like the last. But the stress of a clock change twice a year doesn't have to happen, it's a choice.

This is where I land as well, except I'd go higher. Ukraine has caused the pricing of any FPGA equipped SDR to skyrocket.

Plus incredibly high sample rates that the sSDR supports would likely result in a lot of drops in sampling due to sustained throughput issues of the device itself. You'd be surprised how much dropping occurs on even fairly modern/grunty machines. I used to record X band weather satellite baseband on a HP Dev One and ended up using a ramdisk for baseband recording as the PCIe 2.0 bus wasn't able to handle the sustained write speeds once the nvme drive's buffer was maxed out. Basically anything above 30Msps would go to RAM.

As strong as the lure is of a cute RF device, I've never bought a flipper as I couldn't justify it given the multitude of other SDRs and radio hardware I have. EG RFNM, BladeRF 2.0 xA4, hackRF clone, RTL-SDRs and NESDRs, as well as a YardStick.

3x higher than other rocket builders. Comparing a rocket factory to a construction site it borderline laughable.

Iran currently has tasking control of a single Chinese military spy satellite with sub meter resolution. They struck this arrangement before the war. This capability has provided them targeting/tasking info as well as post attack BDA capabilities.

The delay on commercial imagery purchase isn't to hinder Iran, it's to hinder our understanding of the conflict.

THAAD is the radar systems + missiles. The radar stayed, it was the interceptors that were pulled from Korea. I assume you can accept that to intercept a missile you need tracking and another missile in that system.

You've got to disassemble the boiler and remove the scale from there. I run a Gaggia Classic at home with really hard water and my machine literally stopped flowing due to scale buildup. Once I fully pulled it apart and scraped all the scale out of the inside of the boiler it started running flawlessly.

BO has entered the chat New Glenn and are arguably equal to Super Heavy given they've also recovered and reused their heavy booster.

I think you're going to be surprised at the level of competition BO provides SpaceX in the Artemis program.

I think the initial catalyst for this was when the US/Biden arbitrarily removed Russia from SWIFT post Ukraine invasion. Whether people agreed or disagreed with that decision isn't really material to the discussion, the fact remained that the west decided to remove Russia and they basically had no recourse. And given the, well, unpredictable nature of the current US executive I think it's kinda kicked other countries into overdrive.

Cool. Thanks for demonstrating you have no idea of my usage. I charge every second day as I don't drive far or often. Sometimes I go 3 or more days as I'm actually trying to burn petrol to seat the seals on the pistons of my engine/generator.

Plus my 30kWh battery is Lithium Iron Phosphate. Your BEV is likely a Lithium-Ion? Regardless, I should get 3,000-5,000 full charge cycles on my battery. As long as I charge it to 100% once a week I should be golden.

I have a BYD dealership 25km from my house and a 6 year/150k KM warranty. I'm pretty sure people work there, they definitely were when I visited. Given that I'm pretty sure there are people repairing PHEVs.

Yep, providing front line comms to Russia in the Ukraine war as well as being gifted a virtual oligopoly by the US government is quite the win for their profits.

For the vast majority of entire life Iran has been weeks away from having a nuke. I'm nearly 50. And yet you believe that they're now "two weeks away" because that's what politicians told you. Who's being naive here? How old are you?

> Proof you're wrong is that they had a self-imposed 2000km limit on their missiles but when push came to shove, they changed their mind and shot one 4000km.

The details of this attack are murky, it might not have even occurred. And given the penchant for the Trump administration to lie about this conflict on a daily basis I don't believe it either. Show me some radar tracks, hell, ANY EVIDENCE and I might consider it. Otherwise I'll consider it propaganda.

Not really applicable here imho. Most high power high performance rockets aren't cardboard. The majority are either fibreglass or carbon fibre.

Flex doesn't really become a concern with carbon fibre until you approach Mach 3. I say this because I've built two rockets of an identical design philosophy; one for 54mm motors and one for 75mm motors. The 54mm motor rocket did M2.64 and I could fly it again today if I wanted. The 75mm rekitted itself at M3. It failed where I'd not reinforced the hand rolled airframe that I was flying. 4 wraps of 2x2 200gsm twill CF. Same number I used on the 54mm fine.

For both of these rockets the vast majority of the airframe is directly over a aluminum motor casing that is a rigid body. These things are grossly over-engineered when compared to the pressures/forces they see.

Contrast this with the United States, which does a huge amount of trade with the world and then funnels all of that profit to the poor... /s

I'm not sure where you're getting this idea from, but my PHEV (BYD Shark 6) doesn't drop below 22% battery as the engine is there to charge the battery, not propel the vehicle.

I also believe that most pure BEV drivers would charge their cars daily to mitigate the risk of range anxiety.

We destroyed the nuclear capability of Iran last year during the 12 day war. Trump said so himself.

Now we're engaged in a full regional conflict to destroy Iran's nuclear capability that was destroyed last year. The same capability the Iranians were willing to give up via negotiations that were ongoing when the US and Israel took out the country's leadership in a decapitation strike which began the war.

Respectfully, this war virtually guarantees Iran will now develop nuclear weapons. The exact thing Trump thought shooting them would stop is going to come to fruition because of these actions. The exact thing that was barred by a fatwa since 2004.

How do you not see this?

> we found the maximum altitude estimates were about 15% too high.

this often happens when the wrong rocket finish is selected. Everyone chooses a polished finish when in actuality they've just sprayed the thing with paint.

Skin drag is real.

Thank you! I'm in WA, so in some respects if I'm not driving a landie or hilux my bogan creds are still somewhat lacking, but at least I'm looking down on Ranger drivers now lol.

You're definitely not alone! I just took delivery of a new BYD Shark 6 on Monday. It's amazing and I paid $41k USD ($57,900 AUD) for it. Before that was available I was planning on punting on a used Hilux.

I'm charging my Shark right now and I couldn't be happier. I expect my fuel bill (it's a PHEV) to drop by 70-80% when compared to the 2010 Commodore wagon I was driving last week.
