For the past few years, I didn't have a version of Visual Studio on my main PC (desktop).
When I have had a bit of personal C# to write -- as for a challenge or similar here -- I used an old Win 8 thingy. Which has Visual Studio 2010 Express installed.
And it was good.
Now I have a proper laptop (Win 11) and I installed Visual Studio 2022 Pro.
Today I was copying projects over to the new system and I tested a few to determine whether or not they still compile. They do, but they had to be upgraded from .net 4 to 4.8 -- which is OK. BUT I had forgotten that some of these have an old Installer project which is no longer supported. 
Installers just aren't important enough to me to get me all excited about learning a new tool for creating them. I guess I just won't provide installers anymore.
Or maybe -- just because I probably can -- compile with one version and create installers with the other...
I suppose I can put Visual Studio 2010 Express on here for that.

I've used NSIS for installers for years now. I don't particularly like it but it does its job and I've used the same template script for so long that I don't feel like changing it.
In the end is just like you said:

Oh BTW: lately I've got into shipping one EXE applications just like in the days of good old DOS. They are fancy C++ thingies with an embedded HTTP server and all the UI done through a browser. All nicely packed in a single EXE that contains HTML, CSS, SQL, etc. It would probably make for a nice (and long) article but I don't see many people following on this path, so why bother!

Yeah, that was supposed to be one of the major selling points of .net -- "install by copy" or whatever.

PS Believe it or not, I've survived 20+ years without touching .NET and I don't plan to start now

I have files in .7z format and need to unzip them to do further manipulation.
is this .7z format the same as .zip format in algorithm?
diligent hands rule....

|

|

Maybe not.
I happened to find a .7z file on my system today and I see that 7zip reports it as "Method = LZMA2:14".
7zip doesn't report a Method for a zip file I checked.
File Explorer can open it, but it's possible it use 7zip to do so. I don't know, but 7zip was one of the first things I installed when I got this system.

Hello all,
I have a customer with one 25 years old robot with an industrial computer and windows 95.
That robot computer came with a big chunky 60GB HDD.
Years ago, I replaced that HDD by a Fujitsu SSD with the same size.
Now the customer wants an extra backup (clever) and asked me to buy another SSD to get an image stored there "just in case".
The smallest SSD I've found is +/- 240GB.
I know OSes have limits, is it possible to partition the SSD to fool the computer and make it work even in a 32Bits windows 95? Is that even necessary? will that not be a solution? and is there any solution for that?
Thank you all in advance...

yes. I've done it for years. Wait one...

On one of my embedded projects, the controller OS could only handle DOS-16 - basically nothing larger than 2GB. Now this project started in 2003, it's still deployed. We started with 64MB compact flash. Obviously, over a couple of decades, you simply cannot find these small capacity cards. So, I dug around and came up with the information for resizing the drives.
I mainly used this on Compact Flash cards that were either 4 or 8GB. I have not used it on an SSD, but I cannot think of a reason why it would not work.
Hope this helps.
------------------------------------------------------------------
Before starting, please remember that you can seriously mess things up if you make a mistake using command line disk management. Please make 150% sure you are selecting the correct disk so you don’t format your hard drive. You are solely responsible for anything that happens as a result of using this code 🙂
Instructions for reducing the partition size of a compact flash (CF) card:
Open a command Window (Windows-> Start -> cmd)
Type diskpart
A new window will open up with a “diskpart>” prompt note: if there happen to be network drives, and you are not on the network, this command can take some time.
list disk
select disk n (where n is the number of your CF card)
list volume
select volume n (where n is the number of CF card volume)
clean all (this completely reformats the disk – it will take a while and appear to hang but be patient)
create partition primary (this gives the newly formated CF card a partition so it can be resized)
shrink querymax
This will tell you how much space is currently on available on your CF card. Subtract this from the filesize in MB you want for the final disk than add 1.
For my 4GB disk, shrink querymax returns:
“The maximum number of reclaimable bytes is: 3824MB”
I wanted a final disk size of 2GB which a google search told me is 1954MB so 3824 – 1954 + 1= 1871
shrink desired = 1871 (This tells diskpart to try and shrink the disk by 1871 MB)
Now that the disk is the right size, you can format the partition…
format fs=fat label=”volumelabel”
That’s all it takes.

SSD isn't great for long term storage. They need to be powered on now and then to keep the nand storage active. Rather use a normal HDD for backup and storage.

Have you not checked Amazon?
They have lots of small (and super-cheap) 32GB, 64GB, and similar-range SSDs that go for $20-22. I've seen packs of 10 that go for under $150.
They're so cheap I've bought a pack of 5 just to replace the spinning disks in my old laptops. That was last year; these days you can pay roughly the same price for more than double the capacity.
At that price, if you don't trust them for long-term storage, use the spares for additional backups.

Don't optimize until you have to generally.
But that can sometimes backfire, like when an optimization requires an architecture change.
To save memory and remain flexible, my SVG engine writes its SVGs out using callbacks with color runs and coordinates.
The exception is when
A) your canvas bounds are the same as the bound bitmap bounding box
B) the bitmap is RGBA8888 (32-bit pixels)
I just added an optimization to do direct writes in lieu of using callbacks. It greatly speeds up rendering - if you have the memory for it.
Despite being a totally different way of rendering, I exposed it through a relatively common interface, and automatically direct bind to targets that fulfill A and B:
template<typename Destination>
struct xdraw_canvas_binder {
static gfx_result canvas(Destination& destination, const srect16& bounds, ::gfx::canvas* out_canvas) {
::gfx::canvas result((size16)bounds.dimensions());
gfx_result gr = result.initialize();
if(gr!=gfx_result::success) {
return gr;
}
using st_t = xdraw_canvas_state<Destination>;
st_t* st = (st_t*)malloc(sizeof(st_t));
if(st==nullptr) {
result.deinitialize();
return gfx_result::out_of_memory;
}
st->dest = &destination;
st->dim = (size16)bounds.dimensions();
st->offset = bounds.point1();
*out_canvas=gfx_move(result);
out_canvas->on_write_callback(xdraw_canvas_write_callback<Destination>,st,::free);
out_canvas->on_read_callback(xdraw_canvas_read_callback<Destination>,st,::free);
return gfx_result::success;
}
};
template<>
struct xdraw_canvas_binder<bitmap<rgba_pixel<32>>>
{
static gfx_result canvas(bitmap<rgba_pixel<32>>& destination, const srect16& bounds, ::gfx::canvas* out_canvas) {
::gfx::canvas result((size16)bounds.dimensions());
gfx_result gr = result.initialize();
if(gr!=gfx_result::success) {
return gr;
}
using st_t = xdraw_canvas_state<bitmap<rgba_pixel<32>>>;
st_t* st = (st_t*)malloc(sizeof(st_t));
if(st==nullptr) {
result.deinitialize();
return gfx_result::out_of_memory;
}
st->dest = &destination;
st->dim = (size16)bounds.dimensions();
st->offset = bounds.point1();
*out_canvas=::gfx::helpers::gfx_move(result);
if(bounds==(srect16)destination.bounds()) {
gr=out_canvas->direct_bitmap_rgba32(&destination);
if(gr!=gfx_result::success) {
return gr;
}
} else {
out_canvas->on_write_callback(xdraw_canvas_write_callback<bitmap<rgba_pixel<32>>>,st,::free);
out_canvas->on_read_callback(xdraw_canvas_read_callback<bitmap<rgba_pixel<32>>>,st,::free);
}
return gfx_result::success;
}
};
Here I have a specialization for a general bind and one that binds directly if your pixel format is rgba_pixel<32>
I can then invoke to appropriate method with this lil guy:
template<typename Destination>
static gfx_result canvas(Destination& destination, const srect16& bounds, ::gfx::canvas* out_canvas) {
return xdraw_canvas_binder<Destination>::canvas(destination,bounds,out_canvas);
}
Because I did that, I don't need to change any code that uses ::gfx::draw::canvas<>
Radically different ways of writing, and template specializations to the rescue once again.
A little planning up front led me here, and paid for itself in spades.
Now I have transparent optimization without changing the surface area of my API, even hiding a radical departure in terms of what its draw target is (callbacks vs bitmap writes)
Anyway, as a general rule, I do an optimization pass during many of my design iterations (not version iterations, but process iterations) to make sure I'm not painting myself into a corner. When I do this I assume everything in a critical codepath will need to be optimized. Then I ask myself, "what would that look like and what impact would it have on the final architecture", and I design with that in mind, as I did here.
It's part knack, part luck, and part experience, but optimization shouldn't entirely be ignored during the design phase IMO. Don't optimize, but ask yourself what would optimization do to the design if it has to happen? and then mitigate that in the design.

The best optimizations are usually design changes. Any optimization that requires an architectural change is a design change.
|
|
|
|

I didn't mean to imply otherwise.
Edit: Adding, generally the ones that require design changes are usually "the best" (as in, have the most impact) because they are often what I call algorithmic changes. You can change the way something works as opposed to doing last mile bit twiddling which tends to (except in some cases, like in my SVG direct writes) yield less spectacular results. What I'm talking about in the OP is ways to identify potential areas where a design change might be in order for optimization purposes later, and then designing such that you can shoehorn it in without upending the whole thing.
