As I see it, you got to choose between memory and performance. Using separate fields might be a bit more efficient, but I expect it to require a bit more memory. Unless you can use a unsigned byte of course?
@tinstaafl The field holds all four byte values, I could make them four single-byte fields, but that would mean that the underlying memory order would depend on the order the fields appear in the structure, which would change how the network serializes them. — EBrown2 hours ago
I cannot have the order of bytes ever be different by chance.
The other thing I'm thinking of, since I've changed how serialization is working, is to just replace that private uint with a private byte[] that has four indices.
(This won't work for the other objects like this though.)
public byte[] GetBytes()
{
byte[] result = new byte[SizeInBytes];
uint t = _PackedValue;
Array.Copy(_PackedValue.ToByteArray(), result, 4);
return result;
}
A big disadvantage of your current code is that you create a new byte array every single time you serialize, for each of the objects. That will slow things down, and put pressure on the Garbage Collection. It would be better if you passed a stream along to the GetBytes method (which can be renamed Serialize or WriteBytes). Then you can call stream.WriteByte(...);
I'm creating a meta-utility tool for a project that I'm on that has a lot of repetitive tasks that can eat up a lot of time. My goal with this tool is to eventually be able to automate, or at least facilitate, the vast-majority of grunt-work. I eventually hope to add Django functionality to cre...
@SimonAndréForsberg Since memory storage isn't a problem usually, as long as it's more efficient it's a good trade. Within reason of-course, there is such a thing as using too much. But it doesn't happen often.
@EBrown and return that byte array directly from the byte[] method? That might cause problems if your application is multithreaded and something writes to the color object at the same time as you are passing it through the serialization.
I have a model that consists of several lists that are used in a news feed. For example, there are different lists for sport stories and car stories. I am wondering how I should organise these.
class NewsFeed{
public List<SportStory> sportStories;
public List<CarStory> carStories;
...
Then an array of Color points is made, with the A of each point being set to the respective gray value of the Heightmap, the R is set to the Tempmap, etc.
Then they are normalized, and a chunk is generated.

@Jamal ... in costa rica... got your ping. Good luck. Next week remind me and I will see what's up there. I do a lot of work with Austin folk. My boss's boss is moving there.
On a mobile in the hotel lobby... seriously sucks..... well chat sucks. Not the hotel!!!
I just got done with my Cerner interview. It actually turned out better than the first one, but I sort of stumbled on two technical questions (something about data types for a class and how I worked through a bug in one of my projects or someone else's).
@rolfl Nice! It would be great to get an Austin job with them, and I believe I know where in Austin they're situated.
I don't hang out on CodeReview so apologies if what I'm recommending is off-topic there (be sure to check first!), but based on the text of your question it seems that you should post the code of your middleware on codereview.stackexchange.com to get these recommendations. — Two-Bit Alchemist55 secs ago
@Two-BitAlchemist If OP is willing to include actual code (stub code and example code are not allowed on Code Review), it would be a good fit. — Mast47 secs ago
Here's the scenario:
I have a CSV file, call it csv_file. It has the following content:
Username, Password
name1, pass1
name2, pass2

I also have a dictionary, call it mydict. It has the following content:
mydict = {
"name2" : "pass2",
"name3" : "pass3"
...
}

Unless you can change the generator, you can't really change how it generates the code
Unless you just happened to generate the SQL via these tools, but intend to use it by other means, in which case the generated code is just the starting point
Hmm... this is quite interesting. Facebook has blocked all sharing of jesperwhu.blogg.se , which is a blog by a guy that used to be a member of a certain far-right political party in Sweden. His most recent blog entry was about why he left that political party. Facebook won't allow any sharings of jesperwhu.blogg.se at all, my guess is that this is because of enough people having reported the site as abusive (which it really isn't). Makes you wonder what power Facebook has...
@SimonAndréForsberg Facebook, Google, Microsoft, Apple, they're all giants and all have more power than they should. But hey, the people give it to them anyway.
"Can somebody review my code" - No. Stack Overflow is not about performing code reviews, it's about fixing actual problems that exist in the code. — Captain Obvlious15 secs ago
With so many issues, your question is probably better off on a site like Code Review. StackOverflow is meant for specific questions about specific issues. But let me throw one more bone your way. Use Set WMI = GetObject("winmgmts:\\.\root\CIMV2") to create a WMI object to query the local machine. Also, you're declaring your WMI variable in QADHelper but using it in WaitForProcess. That's not going to work. — Bond9 secs ago
OMG wow. Sorry about that. It runs now but I'm getting a compilation error at the "Set WMI" line saying that the remote server machine is not available or does not exist. — DtheHut3 hours ago
@Fred-ii- I didn't say Stack Overflow was the right place. Indeed this is too broad or primarily opinion based for Stack Overflow. I'm just saying that Code Review is not the right place for this question either, as it is just example code here. — Simon André Forsberg48 secs ago
