So whose surname is "origin of (the) paddy fields" and how do you pronounce it?

Makes me think of cars and motorbikes 

You're cheating, you live there and ought to be able to read like a native. A seven year old native perhaps, but like a native all the same.

You probably also see 本田さん's name over the local tobacconists and suchlike.

Yeah, I didn't want to give it away too easily, maybe my answer was too obvious.

Now how about my name, can anyone tell me what my English name is from this Japanese translation (I'm a little proud of), and what the Japanese characters mean? (No machine translation! )

蛇烈怒

Without machine translation I don't have a hope. There are a very few kanji ideograms I know, and which will jump out if a page of Japanese if I look at it, and I think I've already used 90% of them today. It's fascinating to me that I will notice 日本人 on a page full of other graphically similar characters that are completely and totally meaningless to me. I would say "It's all greek to me" but I did learn a tiny little of that at school, at least enough that the alphabet looks meaningful to me, so perhaps I should say that it's all Russian to me

The literal translation is 'Snake Rage' or 'Snake Fury', which I really want to get embroidered across the back of a 'sukajan' jacket with an intertwined red snake through the characters Yakuza style, but the WAF is rather (extremely!) low... 

A machine translation will only get you halfway though as I am using an alternative pronunciation for the first character, hebi (snake). I am using the pronunciation 'Ja'

No more cheese, too fat (and too expensive anyway). I have now started heavy consumption of fish and vegetables, and see food.

Ah, the "see food" diet as it "see food and eat it". [Fx: rimshot, Sid James' chuckle]

Yes I do the same kind of mistake natives do all the time, I am almost English now !

If you feed that to deepL you have a choice of English (American) or English (British) for an English translation. It gives notably different translations according to the destination language:

snakebite

Alternatives:
snake rage
fierce guardian angel
furious

Serpentine fury

Alternatives:
Serpentine rage
Serpent rage
Serpent's rage

Looks like the Brits feeding it have a rather more poetic turn of phrase than the Americans.

My DM42 gives "1.00000000". Is that precise enough?

 

If I was green of envy now I am purple.... but I already knew that....

1.00000000... even if you press "show" (orange/shift +  ".")? 

in free42 I got 1 but if I press "show" I got



which somehow is more satisfying than a cold 1.

Anyway it is not my method I learned from Dave:

he used a nine, I forgot you could iterate the process to see how fast it will drift from the start number....

36 Kilos weight loss, next objective 40.
Hint: if you are grossly overweight you will most likely have fatty liver which means you ate too much carbs and ruined your insulin. anything containing fructose  will be pure poison for you, anything with other sugars or starch in it diluted poison. you need to bring carb consumption down to less than 20g/ day and replace the carbs with calories from fat, but stay away from any rafficated oils or seed oils.
also, the only fruit allowed will be berries

Interesting, my HP48GX gives .999998113101 to the sin/cos/tan thing, but my HP48GII gives 1.

The windows calculator in Win 10 gives 1.  But I think it may be "cheating."  As you do it, it shows the equation at the top building with each key press, so I wonder if it is smart enough to be cancelling each function with it's inverse to get back the 1.

My first calculator was also the TI-30 and I still have my Great International Math on Keys book somewhere.

[cyclin_al]

It wasn't until much later that a friend coworker explained that while the word meant literally "blond" or of Caucasian descent, the connotation was very similar to "gaijin" in the same context: a specific reference to one being not only white and outsider, but less than human as well; a white ghost.

You're confusing the Japanese Gaijin 外人 = "outside(r)" + "person" (compare Nihonjin 日本人 = sun "日" + origin of "本" + person "人", the Japanese word for "Japanese") with the Chinese Gweilo 鬼佬 = Ghost "鬼" + Man "佬" (compare 中國人 for "Chinese person" = central "中" + state "國" + person "人").

You're probably right on the latter... though I still wish that if they're gonna cuss me out, the least they could do is use enough English that I can be properly offended.

It can be done quite differently as well...

During university, one of my buddies had a Chinese girlfriend.  She taught us all the meaning of "Hum sup lo".
Afterwards, she would unbeknownst to us, lead us into a public area with a large population of Chinese males.
This was easy to do at a university campus with computer and electrical engineering departments.
She would then loudly call us that term, quite loudly, and cause a large audience to give us dirty looks.
It was highly effective because we did realize exactly what had just happened...

It is really a pity, that bd139 is conspicuous by its absence. ;-)

I start to miss him too, he is a smart chap.

[Zucca]

Zucca, I have this beautiful high end stereo set here. May I interest you in some beautifully polished Quadral Montan Mk 3 with a proper power amp ?

I gave up, let me set up my lab properly, then my stereo, then my audio PC with your help 
Only after that we can discuss to upgrade my system.
You know it is a sensible argument for me, and it will always be.

Started work on the HV issues on the two Type 547's. Experimenting to see if I can get the HV to stay up without resorting to removing the HV transformer and figuring out a way to get it rewound.

Schematic of HV circuit.



Making sure the scope still has good power and trace. It does.



All the covers removed exposing the five 5642 HV rectifiers. My initial plan was to just change the HV disc capacitors first. But I discovered that the capacitors are underneath that plastic assembly which would require removal. Quick change in plans and decided to just change the HV rectifiers first and check results. Installing SS rectifiers eliminates the filaments which in turn lightens the load on the HV transformer. So in theory it should run with less load on the HV Oscillator which in turn may prevent a shutdown. That's the theory.




The five SS rectifiers installed. The 5642 HV rectifiers will be kept as spare stock. There's nothing wrong with them. 




Power up and no arcs or sparking. Set the HV test point at the CRT cathode to the spec'ed -1850V.



Perfect trace. Sharp and plenty of brightness. Everything was great, at least for a while. After about 20 minutes noticed the trace was growing both vertically and horizontally. So much so that a 0.5V p-p was displaying in excess of 0.6V p-p. I had already buttoned everything back up so I'm going to have to remove all the covers again and monitor some voltages. That's going to be follow on and I'll post results. 



In other news. The 7B92 500MHz timebase plug-in showed up. It was missing one of the side covers but I have some spares from parts units. Other than that it's in very good shape. Some pictures of the internals. This plug-in is packed tight. At least 3 layers deep. And surprisingly heavy.





Well guess what? Seller sold it as fully functional. It doesn't work. No trigger, no sweep, no trace. I contacted the seller. I'm getting a full refund including shipping and he stated to keep the plug-in. So I'll put it in queue for future repair.

Please keep them entertained as I'm off fishing next week.

The HP48GX will give 1 in RAD mode.

Plus the early "arithmetic" calculators were usually half reverse-polish, e.g to calculate sin(a+b) you entered "a+b=sin".

a+b=sin may be true or false, depending on a, b and the interpretation of sin...

No more cheese

That is quite unparseable. I'm probably more of a French food fan than you, but, as de Gaulle sighed, with 246 varieties, how can one not eat them? (actually, he mostly complained about the impossibility of ruling the French) Speaking of: It's been some time since I had St. Marcellin. Next time I'm walking from work to a underground station a bit further away, I'll try to get some.

Yep, similar. The DM42 of course is a HW platform tuned to run Free42 and nothing else; the true full circle.

Especially as cheese actually contains a lot of protein and the fat in the cheese is good for you ...  The carbs are the killer. Not the fat.

Arh so, its Mr Honda  and in Chinese Cerebus  becomes Serpent Rage, so there is very little difference between Japanese and Chinese it would seem.

Don't we all, but he will be back soon enough, I'm sure, he has this ON OFF relationship with electronics as those who know him will no doubt be aware, he has sold off all his TE gear before and then renewed it again, so folks, watch this space...

A change of topic, I meant to post these earlier but forgot as I have been so busy lately, I did manage to squeeze a trip in to Lakenheath on the 21st in order to capture a few more photos in of the F15C's before they are withdrawn from front line service over here. There will still be F15D and F15E's over here but the F15C's are being replaced with F35's.
These F35's have a strange landing routine, they fly over the airfield at high level and then peel off to gain separation from others in the flight, and then they drop rapidly, levelling out just a few feet from the ground just before the perimeter of the airfield, unlike the F15's which out a reasonable distance and follow a more conventional glide slope.  The F35's are also noticeably far smaller than the old F15's, so you need either a longer focal length on your lens, or you need to be close to them. The F15 is @ 180 mm and F35 is 300 mm, both shot from the same location.

Another reason calculators shouldn't have the misleading and incorrect equals sign 

Too many people confuse computer arithmetic with mathematics. They are in similar domains, but are very different.

The F15 is @ 180 mm and F35 is 300 mm, both shot from the same location.

Maybe they are just showing off. Or perhaps they are minimising the chance of "merging with the ground" outside the airfield boundary.

I wonder if they can fly with only one wing, like the F15?

I wonder if they fall out of the sky if you don't get the sealant on the radome tip cap just right?
