I thought this was funny - a post from Family Handyman. With all the complications we face in life, we have to pick the right color for our windshield washer fluid? I can imagine a TV comedy showing a person freaking out about which color fluid to buy. 😂

Different color windshield wiper fluids are usually dyed for marketing purposes, and, depending on the brand can indicate different things:

Blue: Standard year-round fluid, effective for dust and road dirt.
Green: Summer driving, effective bug remover.
Orange: All-season with deicer, effective against ice and road salt.
Yellow: Winter with deicer, effective melting ice off the windshield with freeze protection up to -34 degrees.
Purple: Concentrated wiper fluid mix for summer.
I thought this was funny - a post from Family Hand... (show quote)


I prepare the fluid myself:
~50 ml kitchen detergent
~100 ml regular alcohol (ethanol)
2 l tap water

No need to dye it... The color is the same as that of the detergent.

What do you think about third party manual? In my opinion I don't think they are helpful for me. I read the manufacturer manuals but not the third party one.


Confucius said that to make a good question, you must know part of the answer.

If we are very experienced with a kind of equipment - say photo apparatus - then we already know 80 % of what's in the manual.

So third party manuals - which have the same info than the manufacturers ones, but more didactical written - are just a waste of money. OEM manuals suffice.

Read the OEM manuals, experiment each feature describe within, and id there is something missing, watch u-tube or some blog.

Taking responsibility for what we buy and use is, apparently, a controversial concept. Over the ten years or so I've been on UHH, and the 50 years of my "aware" life before that, I've noticed that a large number of people seem to gloss over the fact that technology is complex. They buy things that they think they want, but they don't do their research in advance, to be sure that THEY and their new devices, are compatible with what they want to do. They yank them out of the box, plug them in, turn them on, and get disappointed.

"Ready? FIRE!! (Uh, Aim, maybe? You just took out the neighbor's flower pot…)"

We're living in an age where our technical tools are not like hammers and screwdrivers, which are easily mastered by third graders. When you buy a hammer or screwdriver, it doesn't come with a manual, because it doesn't need one. It has a fairly singular purpose and a well-known and understood method of use. But technical gear — cameras, audio, video, computers, and cars — is different. These and many other tools and toys require serious consideration before buying, and serious study before use… IF we are going to get our money's worth from them.

Those of us who write user guides and technical manuals for products and software are usually the first to test the usability and viability of the product. If even the smallest detail doesn't work for us, we explain the issues we find to the product development team AND their directors. Making operation EASY for the customer IS HARD WORK for developers, engineers, and product design staff. It's just as difficult for trainers and training content developers.

One of the unfortunate assumptions companies make about their products is that customers WILL READ the documentation that explains proper use and care. Yet surveys have shown that up to 78% of customers never read it. Many users don't want anything to do with an 830+ page camera manual, or even any sort of a 20 page "Quick Start" guide.

I get all of that, but I also know from hiring many people in a photo lab — and from training school portrait photographers, office staff, and sales people — that understanding and mastering technology requires some quality time, focus, and a certain level of detail orientation. Patience with the documentation and with the entire learning process is usually rewarded with great results and long, trouble-free product life.

There is an old acronym that floated around the Internet BEFORE 1993, when the World Wide Web was born: 'R.T.F.M.' When users got stuck, and posted questions on a bulletin board forum for the tech support staff, the POLITE response was often, "Well, did you read the manual?" Soon enough, that got shortened to the acronym.

"Read The *Fine* Manual!" is the polite version of the acronym. After the tenth or eleventh call from the same user, with the same question, the tech support person would hang up the phone after a call, and yell into a paper bag, substituting whatever 'F' word suited his/her mood.

So here's my simple request to the universe of tech purchasers. Please read the documentation that comes with your purchase, or that you can download from the manufacturer's website at no additional cost. You will learn things you can do with your device that you never thought possible. You will avoid pitfalls that cause 80% of the issues people have with their devices. You will get more done, in less time, with better outcomes! You will trust the maker of the product more, because you understand what they do and don't expect you to do with their devices.

ESPECIALLY if you have used another brand of product in the same class, you need to read the manual just to UNLEARN how your old device of another brand worked. Don't expect brand L to work like brand N. Don't expect brand F to work like brand T. Terminology may be different, control placement may be different, and the way some of the functions work almost certainly will be different.

Don't try to make a Ford drive like a Toyota. It will just annoy you. Don't try to make a Windows PC work like a Mac. It will just frustrate you. They are different brands with different design philosophies and result from different ways of thinking about the same tasks. Take them for what they ARE, not for what they are not.

A little reading won't kill you. Operation may not be obvious, even when you think it should be. There's a reason for everything, and you need to know what it is, if you are going to get along with your new device. Read the freaking manual, and get your money's worth.

I am an Engineer.
So much of my time is spent reading manuals, just checked and my collection is north of 11.000 (pdf + scanned) ones. I select equipment and components to be purchased this way.

My advice is read the manuals *before* you buy the gadget.

It serves two purposes:
1) to help you choose exactly what piece of equipment you really want to buy.
2) it help you start using the equipment quicker, because you already know how to use it.


Besides... reading manuals is a kind of art. You learn how to do it in an efficient manner. Sometimes I read a 1.000 pages manual in one or two days... because I already know 90% of what's in there anyway.

I have this light sensor which is the Avago APDS-9007. I need to attach 4 wires to the 4 corners of the chip. It's intended to mount to a circuit board but I can' make a circuit board. Any idea?
The numbers are 1/10th inches.


This is a SMD chip intended to be soldered by WAVE method on a PCB board which was primed with solder paste.

Design or copy a PCB layout (I use KiCAD for that) with the right footprint and include regular trough hole pads.

Use heat gun for soldering... about 200°C for 5 seconds should be OK.

Or better yet, hire a pro.

You'll have to install Stable Diffusion: https://github.com/CompVis/stable-diffusion
Comfy UI: https://github.com/comfyanonymous/ComfyUI
Download and install a bunch of custom models, nodes, etc.
Maybe - just maybe - learn some coding (not mandatory)

Sure I can.
I'm running open source Comfy UI which in term interfaces with a highly modded Stable Diffusion version in my own Linux computer. I even wrote pieces of the software.
Please note: I do not use any of the "online services"

When I started learning photography in high school there was no such thing as an expensive camera line. You either bought a camera like that your friends had or one you could afford.
The concept of a Hasselblad was out of the question. I wanted to buy a Canon AE-1 but still could not afford one either. I opted for a Russian made Zenit-E. It served me well and still does since it is in good working order.
Now I see it clearer. I have a 5D and was thinking of a mirrorless. But I’m not so sure since my current camera does everything I want. I am not sure I want to throw more money into a well.

What memories!

My dad had a Zeiss Icon E, and I wanted my own camera... the Zeiss was almost as expensive as a HAsselblad, so I also went the Zenit-E plus the 55mm f/2 lens.

The Zenit-E was ** MANUAL **, it took a great involvement to create a good photo, but it could do it.

I gave mine away when I got a AE-1 from my ouncle when he retired as a pro photographer.

It still can be got, here in Uruguay, for about US 10, see: Mercadolibre - Zenit E

What AI program do you use? I use Mid Journey for content that cannot be created with a camera. Art mostly but sometimes putting AI elements with my photography.
Advertisers are already into this. according to recent research, about 14% of commercials on TV are AI-generated at a tremendous cost savings. I catch a few mistakes only a photographer would notice. and yes hands, feet and some plasticity skin is still a big thing with cheap AIs.
Still, and even with phone cameras, they can't compete with a decent photographer and camera, especially a +40mb sensor. We still rule!

Hi, please see my post in https://www.uglyhedgehog.com/tpr?p=14341514&t=794766

You can also see this other post, where I've shown that I can get consistent results (unlike Midjourney) https://www.uglyhedgehog.com/tpr?p=14343584&t=794766

IIRC, PC video cards do not share vram with the cpu cores…


Yes, cheap PCs do.

I've got a bunch of low end i3 laptops and thin clients that share RAM between the graphic card (a N320).

Higher end PCs don't do it because to avoid bottleneck of the PCIe bus. It is preferred to keep quad-channel GDDR RAM close the the graphic chip and connected via 128bit parallel interface - and - the cheaper dual channel DDR RAM on the motherboard.

To share RAM between CPU ang GPU has the only advantage of lowering the cost of the system at the expense of performance.

RAM is cheap nowadays... this is why only lower end systems have this feature.

On a Mac like that, ALL the memory is shared among ALL the processor cores, and the system allocates it dynamically as needed. You won't run out of video memory.


Great!

Wait... that description applies to Linux an Windows (from 2000 up) as well.

Another fine example of Apple's marketing department.

What's next? ALL Mac chassis are made of metal?
