Retirednow. For many years the Teraview on-line real estate /title software required a new password every 2 months or so.

For years I updated the password by going from 123Thisisme to 124Thisisme. When the damn system rejected my password I just backed up a few numbers and tried again, re-iteratively. No post-it notes required. Ended up at 152.... iirc. But I can't remember whether I started with 1 or 100!

Re: Price point

"I still have my T430s that is 7+ years old. "

I'm running an X61 which I bought *used* in 2008. I have replaced the battery, upgraded the RAM, and switched to an SSD and it is still going strong. In fact, now that I think about it, it's had 3 different SSD's in it, each larger than the last (30 -> 128 -> 512 GB). Mine is the X61s with the tablet display and built-in pen storage. WIth the lockdown, it's not been getting a lot of love lately, however.

Re: It is why I buy Thinkpads

How many decades have the ThinkPad faithful been using the TrackPoint?"

At least 2 decades that I know of. I bought a *used* IBM T600 in mid 2001 and it was over 2 years old then.

"Also, there are people (like me, and some of my colleagues) that hate the touchpad with a vengeance. I never managed to get used to it: I use it when I really really have to, but it always come unnatural to me.

If anything, i would welcome a model without the touchpad: I've to actualy disable it, or I tend to accidentaly trigger random mouse movements with my hands otherwise.

P.S. Lenovo also sells external keyboards with trackpoint, and historically i remember some proper large one with it... never managed to get one, tough..."

I detest the scratchy thingy too.

Lenovo sells wired (USB) keyboards with trackpoint. Also available through Amazon, about $60 USD. There is also a Bluetooth model, but it is silly expensive. I've been thinking about the bluetooth version as a replacement for my Logitech Dinovo cordless when it dies. Be nice to have a trackpoint for the desktop computer as well as the X-61.

Re: Closest I've had to that ....

I never realized that winning a Darwin award was actually a competitive event. After the first awardee had removed himself from the gene pool, I am surprised that anyone in the unit would even attempt physical destruction of an unknown pipe.

My suggestion would have been to put a couple of wraps of det-cord around the offending pipe, and retire to a safe distance, and then retire the same distance again just in case the pipe was actually carrying natural gas, or propane, before touching the battery terminals. (Note that I said it was my *suggestion*. If someone said 'here, you can touch this off' my answer would not be 'no' but 'hell no'. The downsides are far greater than the upsides for the actual miscreant. )

Re: There's more..

"It would be good if security auditors could get the status of lawyers re. client confidentiality. Now I'm the first to admit I havent' quite worked through all the negative implications of that (after all, you could be hired by what turns out to be the front of something rather dodgy), but I think security people could do with more protection."

If you are a pentester for hire, you should seriously look into ensuring that you are directly hired by a law-firm acting for the corporation you are to test. That can provide, in some circumstances, complete confidentiality as your work, is legal work-product. If the corporation has no ongoing litigation, or problems with its security, this may not work. But even the fact of being hired by the lawyers, with sign-off from the corporation to be tested (warranty and indemnity agreements, contractual scope of work etc), will be a big CYA in the case of problems.

Long ago, I was present, as a very junior not-to-be-heard-from minion, when a 'pentester' stated that he could get from the outside hall, to the President's office in less than 3 minutes, without tripping the existing alarm. (30th floor of office tower). The President told him to do ahead, so he did. What he did, was to kick a hole in the drywall from the hall, into, as it happened, a storage room, and then mosey down the hall to an office just outside of the range of the motion detecting alarms in reception, and proceed to kick his way through 3 more walls to the President's office. Made it by about 6 seconds.

Took about 2 weeks to get everything repaired. The building management was NOT amused. A LOT of finger pointing and recriminations ensued. He was not hired. But the alarm system was somewhat enhanced thereafter!

Professional Failure

Sounds like a professional failure of the ignorance sort. Presumably he is not completely in the middle of nowhere, so he has a cell signal.

And apparently, no-one has ever told him that he can use his *phone* as a Wifi hotspot to feed his laptop/webcam etc. to the internet using the cell instead of the crappy wired link he is stuck with.

Turn off the home's router. Turn on tethering on the phone and set an SSID, just like on the home router. (You can even set the SSID and password the same as the wired router, so long as you remember not to have both 'on' at once). If available in settings, select a 5G band wifi signal for higher short range throughput over Wifi. Re-set the laptop/webcam to connect to the phone's wifi.

Keep Calm and Carry On.

Yes, this will eat the data quota, but if he is a professional player, it's a cost of doing business.

But then again, an unlimited calls, unlimited data plan could be worth it.

Remember that clinical trial, promoted by President Trump, of a possible COVID-19 cure? So, so, so many questions...

The most important statement in the whole article.

-And because of that, whatever happened in France *must* be wrong and discarded.

Right after those comments by President Trump, Dr. Fauci mentioned that the reports were "anecdotal". To a prissy statistician bureaucrat , everything is 'anecdotal' if it is not a perfectly designed test structure and report with a control group.

To him, if 10,000 doctors treated 100 patients each, and 96% of them recovered, it would still be 'anecdotal' reports. Unless of course, there were another million patients, who were given nothing, (and of which maybe 50% would have died).

Typical of the LameStreamMedia to latch onto President Trump's reference to the drugs being FDA approved and call that a lie (since the FDA has not approved *anything* to treat the coronavirus). But this is not what the President said, nor meant to imply.

There are two things going on here: alleviating patients and doing research. Doing the first can often, and should often conflict with the second.In a more rational world the power of the FDA to obstruct the first would be much more restricted.

Knowing stuff is beneath them

"> It's a kind of snobbery. Knowing stuff is beneath them.

Ah, how I love this kind of people... A few times I managed to handle that was by saying "I do this ONE more time for you and I'll explain things, you better listen.". Some listened, others not. May not be possible in your professional role, though."

For some, it is *doing* stuff which is beneath them. An they will only learn if they are forced to.

All names have been retained to shame the guilty. Long ago, my parents rented a house to an arrogant stuck-up prick by the name of Ivan Head or as I thought of him, "the ASP". Head was a good buddy and ex-classmate of Pierre Trudeau. This was back when Pierre was the PM. The ASP had a habit of yanking on the damper control of the fireplace and pulling the damper (a heavy slab of mild steel) out of position. The slab is only held in position by gravity, so the fix is just to lift it up, align it and drop into place.

I should note that the ASP was bilingual, had 4 degrees, including an Ll.B. and Ph.D, and was a deputy minister rank in the civil service, and was President of the Canadian International Development Agency. He got his job through cronyism I am sure, because he was useless. Despite his education he professed to be unable to use a screwdriver or a hammer. One evening circa summer 1974, he was hosting a dinner party and Pierre Trudeau, his wife and other high eminences were to be guests.

I arrived home and had to have a "strong verbal discussion" with an RCMP officer, after driving past the not-yet-fully-in-place road block, at an "excessive" rate according to said officer, in order to be allowed to enter my parents home, which was next door to the ASP's. And then the ASP called my mother and demanded that I attend to fix the fireplace "which had broken again". This was the third time in 3 months. I attended and found the ASP, all done up in a tuxedo, black tie. He exhibited his usual brusque and demanding persona. But this time, I was pissed that he had refused to learn not to yank on the damper control. And I was pissed at having to have an altercation with a cop, in order to be able to park my car and walk into the house. I wasn't supposed to park in "this driveway".

So this time, I held the flashlight, and made him get down on his hands and knees and fix the 'damage' himself. He actually got *soot* on his hands and almost strained his back bending down to look up into the fireplace. Poor guy. Of course it only takes seconds to fix once you know how the damper is arranged.

The next day he bitched to my mother, about how I had insulted him *by actually making him fix the damper in *her* house*. My mother responded with words to the effect of "you didn't know how to do it, you broke it, and now you are complaining about being taught how to fix it by someone who knows how to do it?"

Re: Bad managers are like knotweed

"I'd be interested if anyone has a notion to explain this ...."

It's a digression from the usual sort of anecdata... but I'll try.

One represents the world of feelings and desire, the other the world of the reality of *getting things done*. The prime advantage of military education (and that includes boot camp/basic) is to bash into everyone's head that the team and the result are of a much higher priority than ego, especially ego which gets in the way of dealing with reality as it is, rather than how you would like it to be.

Sort of BTW, but not really. Earlier this year the USS Fitzgerald collided with a freighter, in Japanese waters. It turns out that the Officer of the Deck on the USS Fitzgerald, and the Officer in charge of the Combat Information Center were engaged in a tiff more appropriate to a pair of 12 year old girls, which they were acting like: they were not speaking to each other. Although CIC was aware of the risk of collision shown by the constant bearing angle between the ships, CIC did not so inform the bridge and trigger some reaction before it was too late. Seven sailors died because of that ego storm.

"Two entirely different creatures, it seems. It's weird."

In 2004, Michael Barone wrote a book about this dichotomy, called 'Hard America, Soft America.'

'A peculiar feature of our country today, says Michael Barone, is that we seem to produce incompetent eighteen-year-olds but remarkably competent thirty-year-olds. Indeed, American students lag behind their peers in other nations, but America remains on the leading edge economically, scientifically, technologically, and militarily.'

A REALLY REALLY interesting read.

Also about then, I read an article in some publication, written by a lefty journalist (but I repeat myself (damn! I just typed 'mysql' and had to go back!)) who was embedded with an Army unit in the sand-box. He was astounded by the men he met: "Where do they find people like this?" They were, of course, completely unlike anything he had ever seen at Columbia U, or Brown. The mind-blower for him, was when a Corporal gave up his lottery-gifted planned satellite phone call to his expectant wife back home, so that the Sergeant could use the platoon's only allowed call, to call the parents of their recently killed brother in arms. The journo could neither imagine nor understand this selflessness: Where do they find people like this? To him it was as if they were grown in Montana or Idaho or Kansas. But such people are not found, they can be and are made. And the modern educational system (including Oxbridge etc) *does not teach that*. STEM at least requires that the bridges not fall down, but that is unfortunately not enough on its own.

Here endeth the digression.

Re: Units


Must write a food reminder to never let you navigate at sea, if you are going to use Glover's as a reference.

A British statute mile is exactly 5280 feet. A US mile is 5280.01056002 feet. (The history of THAT must be interesting! And I did not know that until today.)

But a nautical mile is NOT the same as a British statute mile. A nautical mile was for at least a couple of centuries a 'sea mile' equal to one minute of latitude. And of course, one minute of latitude actually varies with latitude as the earth is not spherical. Generally it was taken as 6080 feet. From about 1890 the British admiralty and the US differently defined a nautical mile to equal one minute of arc of a great circle on Clarke's spheroid (of 1866) approximation of the shape of the earth: 6080 and 6080.2 feet respectively. Both eventually gave that up, and now use the International Hydrographic standard (of 1929) , of exactly 1852 meters or .6076.1154 feet. (Amazing stuff hidden in a copy of Bowditch!)

LOHAN to straddle meaty titanium rod

Dyspeptic Curmudgeon

Simpler Still

Sorry to invite you back to the drawing board., but there IS a better way.

Invert the truss (again!) and make the lowest rail (bottom apex) from a strip of delrin shaped as an inverted keyhole. The truss' structural rods are inserted into holes drilled in the top section of the strip. LOHAN rides along the bottom rounded section. The lower truss then carries out both truss and launcher duties.

You do not need a separte alu plate nor a titanium rod. In the present design, the plate must support the entire load of the rod and LOHAN and hopefully keep them in alignment. Good luck with that.

With a shaped delrin truss tube, the static load of the LOHAN is spread throughout the length of the truss since the delrin is structurally strong. Any torque loads induced by the launch of LOHAN are immediately transmitted into the truss, and the alignment of the LOHAN vis-a-vis the truss is retained. The titanium rod however can bend the plate mounting under load. You need only place a small bolt through the keyhole head to stop LOHAN from sliding off 'backwards.

And delrin because it is light, strong, easly machined, has useful high-temperature characteristics (needs a couple of hundred degrees before it deforms), has basically a nil co-efficent of thermal expansion and has an incredibly low coefficient of friction. In friction terms, its more slippery than ice. And ice is not likely to form on it due to its low thermal conductivity. Only problem is that it IS hard to glue: you do need two part epoxy, but then you probably need that to glue the carbon tubes together anyway.

Attempted ASCII art description of the shape of the delrin truss:


\ /

\ /


Well I hope you get the idea! A variant would be to use an upside down T shape which might be easier to construct. Some passes with a router if constructing from a bar shape, or small screws to fix the 'head' of the T onto the shaft if constructiing from sheet material.
