Up, up, and away...

Up early this morning - teenage son has a grown-up sleep-over to play computer games and D&D, so the house is full of noisy teenagers.

Now I discover that the next Spacex launch (Iridium 5 with 10 Iridium NEXT satellites) is scheduled for tonight (30th March @ 14:13:51 UTC), so I won't be going to bed early to compensate.

I remember watching the grainy black & white images of Neil Armstrong & Buzz Aldrin setting foot on Earth's moon way back in 1969. It was at my grandparents' house, as they were the only ones we knew that owned a TV, and it was over the road from the school. The whole class trooped over to watch, although not all were actually interested.

Now Spacex and other private concerns are bringing the space-faring future that first landing seemed to promise.

How I wish that I had been born 30 years later.

Edit:
OK, so I watched the launch - right up to the point where the Spacex talking head said that the stream  had to end due to NOAA restrictions.

What a crock! Why on off Earth would NOAA have any say on the matter?

The Reddit channel guys are saying that they believe it is a pissing match between Spacex and NOAA because the rocket guys didn't ask nicely for a permit from the government guys to allow them to observe the Earth from space.

It's exactly this sort of fuckery that has the potential to strangle commercial space exploitation in its infancy. Penalty flag against NOAA for appalling behaviour, and I award you no points.

Is (Too Much) Caffeine Good For You?

Took the wife's car to the dealer today for the airbag recall. Well, not actually for the RECALL per se, but for them to document the work that they had already done per the new requirements that came into effect AFTER the start of the recall campaign.

It was expected to only be a half hour or so for them to pull the necessary panels to get access, take a photo, and put it back together, so I wandered over the road to get a coffee.

Said coffee safely consumed, I wandered further, and found a "Barber and Barista". Since I needed a haircut (badly!) I wandered in.

We had a pleasant chat while hair was cut, and when I went to pay, I was told, "Price of the haircut includes a coffee." Well OK.

My phone rang. It was the dealer, calling to tell me that the car was ready, so I turned left instead of right, and headed back. I finished my cup of coffee on the walk back.

Got back to the dealership, sat down with the service writer to go through the paperwork, and the receptionist presented me with - a cup of coffee, made to my preference as noted on my last visit.

Alrighty then - that's four large cups of espresso coffee since I got up at 7:00, and it is almost 9:00.

Can you overdose on caffeine?

Mans' Best Friend: A Remembrance

I read something today about a man and his dog. It was nothing special - a simple account of using a lead/leash with a dog because he (the dog) couldn't be trusted to not do the things he was bred to do.

... and I remembered.

Years ago, I had a dog. A Belgian Shepherd, specifically a Tervueren. Belgians come in four types - a couple of long-hairs, a short-hair, and a rough-hair. The Tervueren is a fawn/mahogany long-hair; a very handsome dog, looking somewhat like a cross between a long-haired collie (think Lassie) and a German Shepherd. Lighter framed than the German, but taller, and a narrower muzzle.

That dog was VERY smart, and I obedience-trained him to follow leash, voice, and visual signals. He went almost everywhere with me, and was never a problem. Well, almost never.

My fiancee and I made a habit of walking the dog in the early evenings - it was usually cooler by then, and we would walk to a large park nearby where he could run. One evening, I had some work-related stuff to finish up, so I told her to go ahead, and that I would be about five minutes. Work duly completed, I grabbed a torch and headed after her.

Now picture this: from the house it was about a three minute walk to a native bush "green-belt" that bordered the park. A narrow path had been trodden through the bush to the park by people like us - too lazy to walk all the way around to the official entrance. Half-way along that path was a larger tree, and sitting at the base of that tree was my dog, with exasperated calls from my fiancee for him to heel echoing across the park.

I stopped. I looked upwards at whatever the dog was looking at in the tree. The man clinging to the trunk four or five metres up was clearly terrified. I called for the dog to heel, which he did without hesitation. I spoke to the erstwhile tree-elf: "Whatever you did to annoy him: DO NOT DO IT AGAIN." I walked away. Silent "come" - step off on your left foot, and the dog (at heel to your left) follows; step off on your right foot, the dog stays.

My fiancee was agitated, telling me that the dog was really disobedient, wouldn't walk at heel at all on the way to the park, insisting on walking five metres behind, and then ran off into the bush before she released him at the park. He was still at heel, so I checked him for any injuries, found nothing, and freed him to run. As he ran, sniffing at everything, and marking each and every tree, fence-post, and goal-post, I explained what had likely happened - she was followed by some ne'er-do-well with evil intent, and the dog sensed it and was being protective. It was a salutory lesson in situational awareness, as she had not even realised that there was somebody behind her. Oh well, problem solved, it's all over, I thought. Not so fast...

A couple of days later, we were doing some weekend gardening in the front yard, with the dog asleep in the shade of a tree. Now the yard was unfenced, but I had no concerns that the dog would run off - he just didn't DO that. A vehicle pulled into the drive. The man who get out was wearing khaki, and introduced himself as the local shire ranger, saying that he was investigating a report of a dangerous dog at this address. My dog had lifted his head at the arrival of the vehicle, looked at me, sensed no reason to alert, and moved only enough to keep me in sight before lying back down. Now think about this - a fawn/mahogany coloured dog, lying on pine bark chips, in dappled sunlight and shade under a tree. He was almost invisible, and the ranger had NO IDEA he was there. Well, I am sure he had SOME skills at his job, but I am guessing they were mostly paperwork related.

After some conversation and being told (forcefully) that I would be held responsible for anything my dog did (he knew I had a dog from shire registration records), he wanted to know where the animal was.

"Right behind you, about three paces. Under the tree."

His head snapped around like he had been slapped. The dog never moved.

"You can't have a dog outside without a leash!"

"Well, actually, the law says, '... in a public place, unless under control ...', and he is not in a public place and is clearly under control, as he hasn't run off."

"You can't control that animal without a leash."

"Want to bet? Watch me."

I held both arms straight up. The dog lifted his head. I crossed my arms, hands to opposite shoulders. I put my right arm straight out, horizontally, pointing in the direction of his kennel. I clapped my hands, once. The dog leapt to his feet, ran through the gateway to his kennel, entered, turned around, and dropped prone in the doorway, watching.

When I turned back to the ranger, I thought I would need to help him lift his jaw off the ground.

After that demonstration, we finally got to the truth of the matter. The tree-elf had reported that he had been attacked by a dog while walking innocently past our house. No injuries, no corroboration, just an allegation. The ranger was duty-bound to investigate, but was now satisfied that there was no problem animal at that address. After being told of the incident from a few nights past, much became clear. The bad guy knew where we lived, had been casing the house, had followed my fiancee with intent, and wanted to be rid of the dog, or at least cause trouble for us. Some discussion ensued as to how we could handle the situation.

The next day, the ranger visited the complainant to advise him of the outcome of his complaint. At that time he realised that he must have left the written complaint form WITH THE COMPLAINANT'S NAME AND ADDRESS in our house while investigating the alleged dangerous dog.

Nothing further ever happened.

God, I miss that dog - RIP, buddy.

Edited to add:
This is a Tervueren. Not MY Tervueren, but a kennel-mate.

... and Lotto fails me again.

Well, I didn't win Lotto, again. So I suppose that means I can't buy that dream car, or dream home, or even dream holiday. Damn!

Still, thinking about it is somewhat revealing. For all the smart choices made in my life - choices that have meant financial stability if not luxury - I HAVE thought about what I would buy with a big Lotto win. Maybe it's true that too many people have "Win the lottery" as their retirement plan.

So, how would I spend $25,000,000?

1. A dream house? Probably not. The house I already own is pretty cool, with the only downside a lack of secure parking. If I were to go through the hassle of moving again, I would want parking for  AT LEAST eight cars, with workshop space, and a hoist. Maybe I could buy the place next door, and "remodel".

2. A dream car? Probably, but which one? Every time I think of a new car, I get caught in the conflict between wanting the best I can get, and the idea of value for money. Do I need a NEW car, or should I let somebody else pay the depreciation? Maybe a lightly used ex-lease vehicle? The latest Porsche 911 Turbo, or a one year old Carrera S? Since the capabilities of the Turbo are almost impossible to test on the road (versus track), I think a nicely optioned lesser model would do just fine - and saving (as in not spending) >$200,000 wouldn't hurt either.

3. A dream holiday? Almost certainly. I've never been to Europe, and I get the feeling that it won't be a somewhat safe travel destination for much longer. Maybe a river cruise from Budapast, with stops at Zuffenhausen (for the Porsche museum), and Stuttgart (for the Mercedes museum), and then I can wing it for the rest. Perhaps buy a new 911 with tourist delivery, and pick it up at the factory, then tour Europe by road for a while.

4. A dream boat? No. Owning a big boat is like having a hole in the water into which you shovel money. Not going to happen.

With that sort of money, I wonder how much life would actually change. There would likely be more trappings of wealth, but as to real change? Probably not much.


The world has gone crazy - part 92,895,445

The organisation known as PETA is more properly People for the Ethical Treatment of Animals (not, as I learned today, People Eating Tasty Animals).

PETA is also another word for crazy - witness their latest insanity:

PETA Says Eating Cheese is Sexist (no link for them - search it yourself)


And eight months later...

Is this thing on?

It's really been eight months since I posted last? Talk about slacking.

I've been REALLY busy! Well, kind of busy. Would you believe moderately occupied?

So many things to do, so little time. Splitting time between house renovations, car projects, competitive shooting, and computers sees little time for much else.

Just when I thought I was getting on top of things, I lost a couple of critical servers, and spent a lot of time rebuilding machines and recovering data. I was running semi-professional systems, RAID disk and all, but decided that replacing the broken systems with real data-center stuff would be a good idea - this wasn't the first time that the semi-pro stuff had let me down.

I picked up a couple of older IBM servers - rack-mount, redundant power, redundant memory, redundant disks, the lot - and migrated everything to freshly installed (and licensed) Windows server 2012, then I picked up a couple more identical servers, and migrated all the other stuff (Linux web stuff, and VMWare mainly). So now the house reverberates to the keening sound of MANY cooling fans, and nobody can sleep, so another project gets started to build a dedicated, sound-proofed, and temperature and humidity controlled server enclosure.

Oh well, at least I taught myself to weld.

Of course all those cooling fans, and power supplies, and disk drives means a spike in the power bill. Solar panels here we come! If only batteries were cheaper.

Funny thing is, the Oz government offers rebates (in the form of traded RECs - Renewable Energy Certificates) that have seen the price of household solar systems not change at all. Before the implementation of the REC system, a 5 kW system cost about AUD$8,000 - immediately after implementation the price was AUD$8,000. Subsequent price drops have all come from improved yields on panel manufacture, improved technology, and economies of scale.

Stupidly the effective maximum allowable capacity of a domestic, grid-connected solar system is 5kW. That's not what the law actually says - it states that the maximum difference in generation capacity between phases is 5 kW - but nobody ever said that the electrical trades draw the best and brightest. Even more stupidly, it is illegal for a solar system to generate power if the grid is down. If the system is NOT connected to the grid, all bets are off, and capacity is dependent on the depth of your pockets. Which brings me back to the ridiculously high cost of batteries. If they were cheaper, I'd go totally off-grid, but to do that would take four (or maybe five) Tesla Storage Wall batteries, and a larger panel farm to feed them. Even then gloomy winter days would see me running the numbers to decide what to shut down. Oh well, first world problems.

Back to more enjoyable subjects, I spent a few weeks thrashing on one of the car projects, and then drove 700 km to a seaside resort for a week. Foolish maybe, as I didn't get everything on the list done, and only had a day and a half of testing before departure, but the car performed almost perfectly. Only minor issues with a slight tyre rub (from larger wheels and tyres than stock), and  a broken ABS sensor wire. Trivial really. The outbound trip was sedate - long weekend, so double demerit points applied - but the home-bound trip was a little faster, as my confidence in the work that I had done increased, and also the police presence on the roads was a little thinner.

Did you know that a four-speed auto equipped V8 will change to SECOND gear at 90 kph if you stand on the throttle? Which of course I would not have done if I hadn't encountered a road user who thought it was funny to do 30 kph less than the speed limit where I couldn't pass, then speed up to 5 kph OVER the limit when passing was possible. I dropped in behind him, and he slowed to 30 under again. Hence, the firm prod of the right foot. The speed warning device in the passenger seat went off at 170, but somehow couldn't detect that I slowed to 140 instead of all the way back top the 110 limit. Oh well.

Enough for now.
