    Is there a way to rewrite git commit messages without it changing the commit date? I split a django app out from the main project and then used rebase to rewrite some commit messages that had references to the old, larger project and it updated my commit times to the time I rewrote even for messages that I chose to keep as is.

    Rebasing will always change the SHA1. And you can't change the commit message without changing the SHA1 as the message is used in part to generate the commit SHA1. The file glob SHA1's for both commits will be the same so it won't be a serious problem.

    They aren't XML serializable out of the gate, but you can do a few things.

    One would be to do a binary serialize of the dictionary object and then stuff that as binary data into a member that then is serialized by your overall XML process.

    Another would be to implement your own SerializableDictionary from Dictionary and IXmlSerializable.

    Or you can XML serialise a list of DictionaryEntry objects and then reconstruct the dictionary with them on deserialisation.

    And then for convenience and cleanness you can put that code in a SerializableDictionary class! ...

    That's kinda how you implement one yes.

    Yeah, I wasn't worried about it breaking anything. I just don't like it having the wrong dates there since that's not actually when I did those commits.

    Is there some way to rewrite commit messages without a rebase that I've missed?

    Dn't worry you are looking at the wrong time anyhow. The Committer time is the last time the message changed. The Author time is the last time the files in the commit changed.

    Ok, yeah, I see where there's a commiter time and author time. Interesting. It annoys me because gitweb is apparently showing stuff based on the comitter time, so it says I did everything 3 days ago on the main display, because that's when I cleaned up the commit messages.

    Wow so, I figured out how to export data from our obtuse EMR billing software that refuses to build an interface to us unless we pay them gobs of money for their full EMR suite. So now I print to a virtual printer that creates a tiff/text combo and forward the tiff to the printer originally used for, then scrape the text file for all relevant data.

    Why the fuck did that have to be so difficult. You should be able to just give me fucking hl7 or even a straight dump of the data.

    The EMR provider we are currently working with gave us full read access to their client's SQL Server database as an integration solution. They plan on giving us write access when we need to start pumping data back in. While the ease of integration is pleasant I am incredibly surprised - and frightened - that this is what they market as their integration API. At least it's through a VPN...

  • bowenbowen How you doin'? Registered User regular
    I would be so happy to have even that. They won't even give me access to the server on site that has their database. It's b-tree I believe. Even if it was b-tree that's way better than scraping data from a print out of a scheduled-fee sheet.

    I do pretty much all my work with the database.

    Which is not consistent with the application front-end and is a mishmash, so some things are rather surprising and it is a lot of time testing-the-app-see-what-the-hell-the-database-does.

    But at least I can get at pretty much anything.

    What's so stupid about this is all we want is for a user when it's created in the billing software to mirror to the actual EMR software. They tacked on an EMR after their billing program was successful probably a few years back. But we had an EMR long before that, so, not paying $80,000 for a new EMR when we've got a perfectly functioning one in house, that can be shaped or modified on the fly.

    So they will only give us demographic data through their HL7 export engine if we buy the full version. Understandable but unacceptable, they declined to give us this interface before they had an EMR in place too because they didn't want us to take our patient data and switch software without re-entering it all. They have a report writer, but that is a piece of shit and gives you first name, last name, and date of birth -- also a dick to try and print shit out from, easier to just type the information again then trying to use their report writer.

    I almost flipped the fuck out on the guy on the phone, but my boss beat me to it. He said if this keeps up he'll stop using them. I would've told them his company is fucking doomed without interoperability regardless if your customer is dropping $100,000 on them or not. It's supposedly going to be required as meaningful use down the line, regardless if your customer only bought the billing portion, it's still gotta talk to the rest.

    I had to write a conversion program from a competitor's app to one of ours like that. There was no documentation of the database, no manual for the software, and had only four days, iirc, of actual testing time with live software. It's amazing how much descriptive field names and a lack of normalization can help with something like that.

    mmmm, foreach. I just had to go through a bunch of javascript at the new job written by an old C/C++ dev and turn for loops into foreach because there were off by one errors in all of them and they required manual fiddling any time new category thingies get added to the site. He's a smart guy, wrote multithreaded c++ stuff that works afaik, so just not up on this fancy newer stuff.

    btw, be careful with the "for(var thing in box)" style of foreach in js. If you're iterating over an Array(), with "for(var thing in box)" you're actually getting the keys because it iterates over the object's dictionary (or something like that). That shit gets me every damned time. JavaScript also has a proper Array.forEach() which returns the values rather than the keys/indexes but IE didn't support it until IE9 so it's not terribly useful.
      myArray = new Array();
      myArray[0] = "zero";
      myArray[1] = "one";
      myArray[2] = 2;
      myArray[3] = 3;
      myArray[4] = 4;
    
      myArray.forEach(function(x) { alert(x)});
    
     /* or if you also want the index, similar to python you can do this.  x and idx may be backwards*/
     myArray.forEach(function(x, idx) {alert("Index is " + idx + " and value is " + x);
    

    Most of the major Javascript libraries implement a .each that resolves browser incompatibilities. Not that Javascript libraries don't introduce their own problems, but it's good to know.

  • InfidelInfidel Heretic Registered User regular
    Also, you're not iterating over an Array() at all, you're enumerating. Big difference in that one is ordered and the other is not.

    If you have an array and want to go over it from first index onwards, use an index / iterator. for-in will give you arbitrary order.

    The company knew they might be leaving and I was made aware from day one. They are leaving more quickly than expected, though. I know enough about the system to rewrite it and can have a 60%-80% working prototype within 1-2 weeks and have fixed several smaller bugs in the existing platform already so I know my way around most of it, so I'm not super worried. I just haven't been working with it long enough to know what I don't know yet, so something is going to slip through the cracks.

  • bowenbowen How you doin'? Registered User regular
    Ahah I had a suspicion it might've been that too. You should be relatively good. I like refactoring older code and porting it to different systems.

    So I have been working on multi threaded applications a bit recently and have come to the decision that I need a good way of keeping a head count on the threads and their interactions with each other. What methods do you employ to do this? I was thinking a flow diagram might be good in some more complex scenarios but I think its a bit more work then required.

    How many threads are you planning on spawning? If it's more than oh, 12ish and they're hard/static threads, I'd recommend you look into a different threading approach that's more scalable. Otherwise, I just do a workflow diagram.

    Fortunately on this, I just need to understand more or less what the code does and the end goals/requirements, which I do (mostly). There's very little that needs directly ported. All of what would have been difficult is going to be handled with Celery and RabbitMQ, which makes it fairly simple.

    There's just inevitably going to be some requirement that was dealt with years ago and forgotten about that no one mentions to me or some weird one off process for just one customer that no one remembers until we think it's all done and that one customer is complaining, etc. I know how this goes. I just did this same thing to some poor guy at my old job when I left. I tried to think of all the stupid little crap and document it, but there was a lot, so I'm sure I missed something.

    In a way this makes things easier. The old platform was completely designed and mostly developed by one of the guys leaving. It was his pet project and he was really proud of some parts of it. There were some parts that he was clearly trying to save and not see someone rewrite. Now I can just do what needs done and not feel like I'm stepping on anyone's toes when I do it.

    What are you planning on doing with RabbitMQ? I've used before and it's nice, but you have you to watch your traffic rates through it. More than 15,000 messages/second and we started dropping brokers. We ended up just going with straight UDP (well, DBL) packets. But for lower volume stuff, it works great.

  • Jimmy KingJimmy King Registered User regular
    I'm going to be using it as the broker for Celery integrated with Django. It'll be used for distributing tasks to celery workers which will primarily be processing ingoing and outgoing sms messages and various once/day type stuff like tallying up votes from sms polls, picking winners for contests, etc. It shouldn't be anywhere near 15000/second. Our current SMS endpoint lets us send at up to 8 messages/second before charging a ton more and I don't think we normally do that (although we could during burst traffic situations and could go over, but still wouldn't need 15k/second), plus whatever incoming which is at a far, far lower rate than the outgoing, and those one off once/day schedule tasks.

    RabbitMQ is overkill really, but it gives room to grow, isn't that difficult to set up, and the devs working on our team's other main project have some ideas for using it with their project as well.

    Oh I have. Not as bad as templewulf's code nightmares but I hate it when customers change their mind, tell me 8 things, then change it to 10 things, and none of the 8 things work the way they want because their secretary described it instead of them. Fucking sales people.

    I saw a language popularity comparison in an RSS feed today. It seems VB still holds the title for most books about a language with fewest jobs. Link is here.

    It's sad to see the high number of job postings for PHP, but I suspect a lot of that is the low end "get a web guy" type of stuff. I suspect non-Craigslist sources would skew more towards higher level, though I might be a little biased.

    I don't know what the big hubub against PHP is. It's not like people are decrying C or C++. I'd rather use PHP than ASP and I'd be on the fence about rails too.

    Yeah, there's a moderate amount of professional php dev around here. It's been around long enough and is well known enough that it's a safe bet to go with if you don't want or need MS or Java stuff. I suspect it is also related to the "get a web guy" thing, though. More developers, more entry level devs using it, so easier to hire people and to find cheap devs (both small, "get a web guy" shops and big, professional companies just being cheap).

    Python is only recently gaining a lot of traction from what I've seen. It's growing where I am and now is a good time to get in on the ground floor. It also seems to have a much higher proportion of experienced (or at least intelligent/competent) devs using it (probably due to not having much popularity until within the last few years), which may mean a lot of talk online by guys who live and breathe dev, but less need for books and fewer and more expensive developers when it comes to hiring. If Python keeps growing, that'll change and the noobs will start using it more.

  • an_altan_alt Registered User regular
    I have two things against PHP, neither of which is probably fair.

    First is the feel of it. It seems that it was a scrub language that had all its features added after the fact, instead of being a natural part of it. I spend a lot of time in a language in a similar situation, but at least it has the decency to be old, whereas PHP doesn't have that excuse.

    The second thing is my experience with PHP coders. I've met a bunch of competent developers who also do some work in PHP. Those who identify as PHP programmers tend to be much rougher around the edges professionally.

    I really hope Python continues to grow. I like it so much more than anything else I have tried.

    I've only casually looked but I've seen a few job postings for it, so I'm hopeful I can find something when I actually do feel comfortable enough to start sending out applications.
