• From the Tips Box: Revitalizing Ink Cartridges with a Water Infusion

  - by Jason Fitzpatrick

  If you’re convinced your ink cartridge has more ink to share than it is willing to give up, you’re right. Read on to see how How-To Geek reader Max squeezes extra life out of his cartridges with plain old water. Max wrote in with his simple solution. He wasn’t as interested in refilling his cartridges as he was in getting all the ink out of them. Here’s his detailed guide to getting nearly every drop of ink out of your high-priced ink cartridge: The ink in many brands of ink jet printer cartridges is generally water soluble. To see if your ink is water soluble, wet your finger and rub it across a page from your printer you don’t mind wasting.  If the print smears the ink is obviously water soluble. The top of the printer cartridge generally has the manufacturer’s label attached. It covers tiny holes through which the ink was injected into the cartridge during manufacture.

• Is there a way to add unique items to an array without doing a ton of comparisons?

  - by hydroparadise

  Please bare with me, I want this to be as language agnostic as possible becuase of the languages I am working with (One of which is a language called PowerOn). However, most languanges support for loops and arrays. Say I have the following list in an aray: 0x 0 Foo 1x 1 Bar 2x 0 Widget 3x 1 Whatsit 4x 0 Foo 5x 1 Bar Anything with a 1 should be uniqely added to another array with the following result: 0x 1 Bar 1x 1 Whatsit Keep in mind this is a very elementry example. In reality, I am dealing with 10's of thousands of elements on the old list. Here is what I have so far. Pseudo Code: For each element in oldlist For each element in newlist Compare If values oldlist.element equals newlist.element, break new list loop If reached end of newlist with with nothing equal from oldlist, add value from old list to new list End End Is there a better way of doing this? Algorithmicly, is there any room for improvement? And as a bonus qeustion, what is the O notation for this type of algorithm (if there is one)?

• What kind of code would Kent Beck avoid unit testing?

  - by tieTYT

  I've been watching a few of the Is TDD Dead? talks on youtube, and one of the things that surprised me is Kent Beck seems to acknowledge that there are just some kinds of programs that aren't worth unit testing. For example, right here DHH says that Kent Beck is ... very happy to say "Well, TDD doesn't fit in this case, I'm just going to bail" It's frustrating to me that Kent Beck seems to acknowledge this, but nobody asks him to elaborate on it or give concrete examples. I'd like to know the situations where Kent Beck thinks TDD is a bad fit. Nobody can read his mind or speak for him, but I'm hoping he's been transparent enough through his books/tweets/whatever for someone to be able to answer. I'm not necessarily going to take what he says as gospel, but it would be useful to know that the times I've tried TDD and it just felt impossible/useless are situations that he would have bailed on it himself. Or, if it turned out he would have tested that code it'd suggest to me that I was approaching the process very wrong. I also think it would be enlightening to understand why he would bail on such projects. My opinion on why this is not a duplicate of "When is it appropriate to not unit test?" After skimming those answers I'm not satisfied. For example, look at UncleBob's answer. He doesn't even acknowledge that such a situation exists. I really think there's value in understanding Kent Beck's position, not just a general, "What's your opinion?" type of question. After all, he's the father of TDD.

• Where to find and install ASUS motherboard drivers for Linux

  - by Dan

  This is my second day ever with Linux, and I had one heck of a time getting the nVidia drivers installed and working. Please, keep in mind I am very new and just starting out. I currently have an ASUS P8Z68-V LE motherboard and I'm not sure if the drivers are installed. Where would I go to find that out? I am using Gnome as my UI. If I don't have the drivers installed, where would I go? The ASUS site only gives me options to download for various Windows OS, DOS and "other" (in .ROM format). Which should I take and how should I install? I'm mostly looking for audio drivers. A lot of music I play, either on YouTube or with VLC has a faint crackling in the background on Ubuntu, which gets much worse the higher I turn the volume up. Could this be something other than the drivers? I doubt it's the hardware since the sound seems fine on Windows. I am currently running 12.04.

• Strict Pomodoro and other time management Chrome extensions

  - by kerry

  I have recently begun using the Pomodoro Technique to increase my productivity. However, I still find myself getting sucked in to the vortex of useless information that is the internet. With that in mind I began searching for a useful chrome extension to replace the Android Pomodoro app I have been using to manage my ‘doros. I even considered writing it myself. Luckily, I stumbled on one that had a similar featureset to what I was looking for. Strict Pomodoro is an excellent Chrome extension for practicing Pomodoro. Though lacking a few key features, such as the ability to set the duration of your pomodoros and breaks, it still has a key feature that helps me stay on task. It blocks time sucking websites. You can set filter lists and it will keep you from accessing them during a Pomodoro. Effectively reminding you to stay on task. Also, the author readily admits that it was quickly put together and new features may be added down the road. For now, it is still an excellent option. For those of you who do not practice Pomodoro but are trying to stay on task. The StayFocusd extension will effectively manage the amount of time you spend on useless (non-productive) sites. It also has a rich feature set that may be better for your work habits. OK, breaks over. Time to get back to work. 25 minutes at a time.

• Quoting people for website dev. work

  - by Jason

  Hi All, I have recently given some quotes to a few people. And I need some advice about how things should be done... Q1: I've seen, heard of and read about a lot of developers using free resource sites online to obtain free Privacy Policy, Disclaimers etc for their/customers websites. A customer I quoted the other day expected me to write/get a disclaimer for their site. Who in their right mind would expect a document like that from a Web Developer? I just told them that they need to sort that stuff out themselves with a Lawyer or something, and then to send it to me so I can paste it on a webpage for them. Q2: If you're charging per hour, and you estimate that the project would take 1week to finish (including testing/releasing), but you soon realise that you'll require more time, do you RE-quote them? Or do you just finish off the site at the original quote price? Q3: How do you figure out how much you will charge your customers? Do you charge per-feature, or per hour, or per day, or all of the above? Thanks :)

• Thinktecture IdentityServer v1.0

  - by Your DisplayName here!

  Yeah – it is finally done. I just uploaded the v1 bits to Codeplex and the documentation to our server. Here’s the official blurb… Thinktecture IdentityServer is an open source security token service based on Microsoft .NET, ASP.NET MVC, WCF and WIF. High level features Multiple protocols support (WS-Trust, WS-Federation, OAuth2, WRAP, JSNotify, HTTP GET) Multiple token support (SAML 1.1/2.0, SWT) Out of the box integration with ASP.NET membership, roles and profile Support for username/password and client certificates authentication Support for WS-Federation metadata Support for WS-Trust identity delegation Extensibility points to customize configuration and user management handling Disclaimer I did thorough testing of all features of IdentityServer - but keep in mind that this is an open source project and I am the only architect, developer and tester on the team. IdentityServer also lacks many of the enterprise-level features like configuration services, proxy support, operations integration etc. I only recommend using IdentityServer if you also understand how it works (to be able to support it). I am offering consulting to help you with customization and lock down - contact me. Download. Documentation. Up next is v1 of the Azure version. Have fun!

• How&rsquo;s your Momma an&rsquo; them?

  - by Bill Jones Jr.

  When a Southern “boy” like me sees somebody that used to be, or should be, a close friend or relative that they haven’t seen in a long time, that’s a typical greeting.  Come to think of it, we were often related to close friends. So “back in the day”, we not only knew people but everybody close to them.  When I started driving, my Dad told me to always drive carefully in Polk county.  He said if I ran into anybody there, it was likely they would be related or close family friends. Not so much any more… the cities have gotten bigger and more people come south and stay.  One of the curses of air conditioning I guess. Anyway, it’s been a while.  So “How’s your Momma and them”?  Have you been waiting for me to blog again?  Too bad, I’m back anyway <smile>. Here in Charlotte we just had another great code camp.  The Enterprise Developers Guild is going strong, thanks to the help of a lot of dedicated people.  Mark Wilson, Brian Gough, Syl Walker, Ghayth Hilal, Alberto Botero, Dan Thyer, Jean Doiron, Matt Duffield all come to mind.  Plus all the regulars who volunteer for every special event we have. Brian Gough put on a successful SharePoint Saturday.  Rafael Salas and our friends at the local Pass SQL group had a great SQL Saturday.  Brian Hitney and Glen Gordon keep on doing their usual great job for developers in the southeast as our local Microsoft reps. Since my last post, I have the honor of being designated the INetA Membership Mentor for Georgia in addition to mentoring the groups in the Carolinas for the past several years.  Georgia could be a really good thing since my wife likes shopping in Atlanta, not to mention how much we both like Georgia in general.  As I recall, my Momma had people in Georgia.  Wonder how their “Mommas an’ them” are doing?   Bill J

• C#.NET (AForge) against Java (JavaCV, JMF) for video processing

  - by Leron

  I'm starting to get really confused looking deeper and deeper at video processing world and searching for optimal choices. This is the reason to post this and some other questions to try and navigate myself in the best possible way. I really like Java, working with Java, coding with Java, at the same time C# is not that different from Java and Visual Studio is maybe the best IDE I've been working with. So even though I really want to do my projects in Java so I can get better and better Java programmer at the same time I'm really attract to video processing and even though I'm still at the beginning of this journey I want to take the right path. So I'm really in doubt could Java be used in a production environment for serious video processing software. As the title says I already have been looking at maybe the two most used technologies for video processing in Java - JMF and JavaCV and I'm starting to think that even they are used and they provide some functionality, when it comes to real work and real project that's not the first thing that comes to once mind, I mean to someone that have a professional opinion about this. On the other hand I haven't got the time to investigate .NET (c# specificly) options but even AForge looks a lot more serious library then those provided for Java. So in general -either ways I'm gonna spend a lot of time learning some technology and trying to do something that make sense with it, but my plan is at the end the thing that I'll eventually come up to be my headline project. To represent my skills and eventually help me find a job in the field. So I really don't want to spend time learning something that will give me the programming result I want but at the same time is not something that is needed in the real world development. So what is your opinion, which language, technology is better for this specific issue. Which one worths more in terms that I specified above?

• Changing frontend cache

  - by Utsav

  Our architecture consists of a front-end cache that most read only users obtain their data from directly. The front-end cache sits in front of a farm of webservers that serve pages written in PHP. We need to be able to detect certain conditions at the front-end cache level and pass those values through to the back-end via HTTP headers. For example we would like to manually tag the carrier network based on the IP address. So, for incoming traffic if the user is say coming from an IP address in the range of "41.202.192.0"/19 we would tag them as being a Orange Cameroon user by setting the appropriate HTTP request header, e.g., X-Carrier = "Orange Cameroon". Based on the setting of this header we would like to vary the cache and serve a different banner to the end user. How would you go about doing this? Keep in mind that we don't want to pollute the cache and we also don't want to create too many small cache segments. Assumptions: You can assume that the X-Carrier has already been detected in our cache. So, for the purposes of your test you can just set this value manually in your example script.

• How to use shared_ptr for COM interface pointers

  - by Seefer

  I've been reading about various usage advice relating to the new c++ standard smart pointers unique_ptr, shared_ptr and weak_ptr and generally 'grok' what they are about when I'm writing my own code that declares and consumes them. However, all the discussions I've read seem restricted to this simple usage situation where the programmer is using smart in his/her own code, with no real discussion on techniques when having to work with libraries that expect raw pointers or other types of 'smart pointers' such as COM interface pointers. Specifically I'm learning my way through C++ by attempting to get a standard Win32 real-time game loop up and running that uses Direct2D & DirectWrite to render text to the display showing frames per second. My first task with Direct2D is in creating a Direct2D Factory object with the following code from the Direct2D examples on MSDN: ID2D1Factory* pD2DFactory = nullptr; HRESULT hr = D2D1CreateFactory(D2D1_FACTORY_TYPE_SINGLE_THREADED, &pD2DFactory); pD2DFactory is obviously an 'out' parameter and it's here where I become uncertain how to make use of smart pointers in this context, if indeed it's possible. My inexperienced C++ mind tells me I have two problems: With pD2DFactory being a COM interface pointer type, how would smart_ptr work with the Add() / Release() member functions for a COM object instance? Are smart pointers able to be passed to functions in situations where the function is using an 'out' pointer parameter technique? I did experiment with the alternative of using _com_ptr_t in the comip.h header file to help with pointer lifetime management and declared the pD2DFactory pointer with the following code: _com_ptr_t<_com_IIID<pD2DFactory, &__uuidof(pD2DFactory)>> pD2DFactory = nullptr; and it appears to work so far but, as you can see, the syntax is cumbersome :) So, I was wondering if any C++ gurus here could confirm whether smart pointers are able to help in cases like this and provide examples of usage, or point me to more in-depth discussions of smart pointer usage when needing to work with other code libraries that know nothing of them. Or is it simply a case of my trying to use the wrong tool for the job? :)

• Session state provider and atomic operations

  - by vtortola

  Hi, I've been thinking about this and it is blowing my mind... How does a session state provider properly works internally? I mean, I tried to write a custom session state provider based on Azure Tables or Blobs, but quickly I realized that because there is no way to ensure an atomic operation or establish a lock, race conditions are suitable to happen when several web servers do operation on that shared information. I know that there is a SQL Server Session State Provider (SQLS-SSP) and people is happy with it, so I guess that it's using some kind of transaction isolation level in order to accomplish some degree of concurrent safety, like checking is the data is lock (a simple column), locking it if not and returning the data in an atomic operation, but is that so? what does happen if the data is lock? does it returns an error? block the call for a while? returns it in read-only fashion? Cloud computing paradigms could be somehow new, but webfarms have been here for a while, so as I'm pretty new on it... do you recommend any good lecture about the topic? Thanks.

• SSDT gotcha – Moving a file erases code analysis suppressions

  - by jamiet

  I discovered a little wrinkle in SSDT today that is worth knowing about if you are managing your database schemas using SSDT. In short, if a file is moved to a different folder in the project then any code analysis suppressions that reference that file will disappear from the suppression file. This makes sense if you think about it because the paths stored in the suppression file are no longer valid, but you probably won’t be aware of it until it happens to you. If you don’t know what code analysis is or you don’t know what the suppression file is then you can probably stop reading now, otherwise read on for a simple short demo. Let’s create a new project and add a stored procedure to it called sp_dummy. Naming stored procedures with a sp_ prefix is generally frowned upon and hence SSDT static code analysis will look for occurrences of this and flag them. So, the next thing we need to do is turn on static code analysis in the project properties: A subsequent build causes a code analysis warning as we might expect: Let’s suppose we actually don’t mind stored procedures with sp_ prefixes, we can just right-click on the message to suppress and get rid of it: That causes a suppression file to get created in our project: Notice that the suppression file contains a relative path to the file that has had the suppression placed upon it. Now if we simply move the file within our project to a new folder notice that the suppression that we just created gets removed from the suppression file: As I alluded above this behaviour is intuitive because the path originally stored in the suppression file is no longer relevant but you’re probably not going to be aware of it until it happens to you and messages that you thought you had suppressed start appearing again. Definitely one to be aware of. @Jamiet

• Is rotating the lead developer a good or bad idea?

  - by Renesis

  I work on a team that has been flat organizationally since it's creation several months ago. My manager is non-technical and this means that our whole team is responsible for decision-making. My manager is beginning to realize that there are several benefits to having a lead developer, both for his sake (a single point of contact and single responsible party for tasks) and ours (dispute resolution, organized technical guidance, etc.). Because the team has been flat, one concern is that picking one lead developer may discourage the others. A non-developer suggested to my manager that rotating the lead developer is a possible way to avoid this issue. One developer would be lead one month, another the next, and so on. Is this a good idea? Why or why not? Keep in mind that this means all developers — All developers are good, but not necessarily equally suited to leadership. And if it is not, suppose I am likely the best candidate for lead developer — how do I recommend that we avoid this approach without looking like it's merely for selfish reasons? (In other words, the team is small enough that anyone recommending a single leader is likely to appear to be recommending themselves — especially those who have been part of the team longer.)

• GParted in UBUNTU shows entire disk as UNALLOCATED SPACE

  - by msPeachy

  Good day to everyone. I hope someone can help me with my problem. I have a dual boot Windows and Ubuntu system. I recently encountered an hd0 out of disk error and wasn't able to boot Ubuntu. So I booted into Windows, after 2 to 3 times of booting and rebooting Windows, I tried booting Ubuntu but still I get the hd0 out of disk error. I decided to run Ubuntu from LIVEUSB to try to fix my Ubuntu partition using GParted, but when I run GParted, it shows my entire disk as UNALLOCATED SPACE! The strange thing is that Nautilus still shows and mounts my partitions. Also every time I boot into Windows , my partitions exists and I am able to read and write to them. I have no idea what is wrong. Please help! I can't stand using Windows since most of the tools I use are in Ubuntu. I don't mind reinstalling Ubuntu. In fact I already tried reinstalling using the LIVEUSB but I wasn't able to, since GParted or the Ubuntu installer itself does not recognized my partitions and shows the entire disk as unallocated space. I am currently running Ubuntu from LIVEUSB. Here's the outpuf of sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb30ab30a Device Boot Start End Blocks Id System /dev/sda1 * 2048 104869887 52433920 83 Linux /dev/sda2 104869888 105074687 102400 7 HPFS/NTFS/exFAT /dev/sda3 105074688 156149759 25537536 7 HPFS/NTFS/exFAT /dev/sda4 156151800 625153409 234500805 f W95 Ext'd (LBA) /dev/sda5 156151808 169156591 6502392 82 Linux swap / Solaris /dev/sda6 169158656 294991871 62916608 7 HPFS/NTFS/exFAT /dev/sda7 294993920 471037944 88022012+ 7 HPFS/NTFS/exFAT /dev/sda8 471041928 625121152 77039612+ 7 HPFS/NTFS/exFAT When I run, sudo parted -l, I got this error message: ubuntu@ubuntu:~$ sudo parted -l Error: Can't have a partition outside the disk!

• From physics to Java programmer?

  - by inovaovao

  I'm a physics phd with little actual programming experience. I've always liked programming and played around with Basic and Pascal (also VB and Delphi) as a teen, but the largest actual project I completed was an assignement for the introductory computer science class in university where I wrote a nice little program (about 1500 lines of pascal) to display functions of 2 variables in 3D. I've had also a couple other projects of a few hundred lines range, but during my phd I didn't have (or take) the time to program more (string theory is hard guys!), beside playing around with ruby. Now I've decided that I'm more interested in programming than in physics and started to learn Java (hoping to pass the certification exam next week) and OO design. Still, I have trouble deciding on what to focus next (Java EE? Web development? algorithms and C programming?) in order to maximize my employement chances. Bear in mind that I'm aiming (mostly) at the swedish job market and that I'm 30 years old. So for the questions: Do you think that I have any chances to start and make a career in IT and programming coming from physics? What would be the best strategy to maximize my value in the field? Do you have suggestions as to where my physics background might be useful?

• Column order can matter

  - by Dave Ballantyne

  Ordinarily, column order of a SQL statement does not matter. Select a,b,c from table will produce the same execution plan as   Select c,b,a from table However, sometimes it can make a difference.   Consider this statement (maxdop is used to make a simpler plan and has no impact to the main point):   select SalesOrderID, CustomerID, OrderDate, ROW_NUMBER() over (Partition By CustomerId order by OrderDate asc) as RownAsc, ROW_NUMBER() over (Partition By CustomerId order by OrderDate Desc) as RownDesc from sales.SalesOrderHeader order by CustomerID,OrderDateoption(maxdop 1) If you look at the execution plan, you will see similar to this That is three sorts.  One for RownAsc,  one for RownDesc and the final one for the ‘Order by’ clause.  Sorting is an expensive operation and one that should be avoided if possible.  So with this in mind, it may come as some surprise that the optimizer does not re-order operations to group them together when the incoming data is in a similar (if not exactly the same) sorted sequence.  A simple change to swap the RownAsc and RownDesc columns to produce this statement : select SalesOrderID, CustomerID, OrderDate, ROW_NUMBER() over (Partition By CustomerId order by OrderDate Desc) as RownDesc , ROW_NUMBER() over (Partition By CustomerId order by OrderDate asc) as RownAsc from Sales.SalesOrderHeader order by CustomerID,OrderDateoption(maxdop 1) Will result a different and more efficient query plan with one less sort. The optimizer, although unable to automatically re-order operations, HAS taken advantage of the data ordering if it is as required.  This is well worth taking advantage of if you have different sorting requirements in one statement. Try grouping the functions that require the same order together and save yourself a few extra sorts.

• Is there any evidence that drugs can actually help programmers produce "better" code? [closed]

  - by sytycs

  I just read this quote from Steve Jobs: "Doing LSD was one of the two or three most important things I have done in my life." Also a quote from that article: He was hardly alone among computer scientists in his appreciation of hallucinogenics and their capacity to liberate human thought from the prison of the mind. Now I'm wondering if there's any evidence to support the theory that drugs can help make a "better" programmer. Has there ever been a study where programmers have been given drugs to see if they could produce "better" code? Is there a well-known programming concept or piece of code which originated from people who were on drugs? EDIT So I did a little more research and it turns out Dennis R. Wier actually documented how he took LSD to wrap his head around a coding project: "At one point in the project I could not get an overall viewpoint for the operation of the entire system. It really was too much for my brain to keep all the subtle aspects and processing nuances clear so I could get a processing and design overview. After struggling with this problem for a few weeks, I decided to use a little acid to see if it would enable a breakthrough, because otherwise, I would not be able to complete the project and be certain of a consistent overall design"[1] There is also an interesting article on wired about Kevin Herbet, who used LSD to solve tough technical problems and chemist Kary Mullis even said "...that LSD had helped him develop the polymerase chain reaction that helps amplify specific DNA sequences."

• Logarithmic spacing of FFT bins

  - by Mykel Stone

  I'm trying to do the examples within the GameDev.net Beat Detection article ( http://archive.gamedev.net/archive/reference/programming/features/beatdetection/index.html ) I have no issue with performing a FFT and getting the frequency data and doing most of the article. I'm running into trouble though in the section 2.B, Enhancements and beat decision factors. in this section the author gives 3 equations numbered R10-R12 to be used to determine how many bins go into each subband: R10 - Linear increase of the width of the subband with its index R11 - We can choose for example the width of the first subband R12 - The sum of all the widths must not exceed 1024 He says the following in the article: "Once you have equations (R11) and (R12) it is fairly easy to extract 'a' and 'b', and thus to find the law of the 'wi'. This calculus of 'a' and 'b' must be made manually and 'a' and 'b' defined as constants in the source; indeed they do not vary during the song." However, I cannot seem to understand how these values are calculated...I'm probably missing something simple, but learning fourier analysis in a couple of weeks has left me Decimated-in-Mind and I cannot seem to see it.

• Page Inspector and Visual Studio 2012

  - by nikolaosk

  In this post I will be looking into a new feature that has been added to theVS 2012 IDE. I am talking about Page Inspector that gives developers a very good/handy way to identify layout issues and to find out which part of server side code is responsible for that HTML snippet of code.If you are interested in reading other posts about VS 2012 and .Net 4.5 please have a look here and here.This tool is integrated into the VS 2012 IDE.We can launch it in different ways. 1) We will create a new ASP.Net MVC application (an Internet application). I will not add any code.2) In the Solution Explorer I choose my project and right-click. From the available options select View in Page InspectorHave a look at the picture below.  3) We can launch Page Inspector from the Standard Toolbar. Please have a look at the picture below.   4) Let's view our application with Page Inspector. First I inspect the About link-menu.I can see very quickly the HTML that is rendering for that link to appear. I also see the server side code (the actual view, _Layout.cshtml) that is responsible for that link. This is something developers always craved for. We can also see the CSS styles that are used to style this link (About).Have a look at the picture below Obviously there are similar tools that I have been using in the past when I wanted to change a part of the HTML or see what piece of CSS code affects my layout. I used Firebug when viewing my web applications in the Firefox browser. Internet Explorer and Chrome have also great similar tools that help web developers to identify issues with a site's appearance/issues.Please bear in mind that Page Inspector works with all forms of the ASP.Net stack e.g Web Forms,Web Pages.Hope it helps!!!!!

• Memory concerns while plotting escape from DLL Hell in Delphi

  - by Peter Turner

  I work on a program with about 50 DLLs that are loaded from one executable, it's an old organically grown program where the only rationale for creating a new DLL is that one previously didn't exist to fill a given need. (and namespaces didn't exist in Delphi so it never crossed our mind to make dll1.main.pas, dll2.main.pas or something even more unique) What we want to do is consolidate all these DLLs into one executable, since none of them are used out of the program, there shouldn't be much of a problem. The concern my boss has is that if we did this, the memory overhead for terminal server clients would go through the roof. So, I've stepped through enough initialization code to know that lots of stuff is done every time a DLL is loaded in to memory, but say I've got a project with about 4000 files, and 50 dlls, 10 of which are probably utilized by any one user in any one session of the program. The 50 dlls are about 2/3rds form files, if not more, but beyond that there's not a lot of other resources being loaded (only a few embedded pictures, icons, cursors, etc..). If I loaded all these files in to memory, how much memory is used per unit? how much is used per class? How do I keep the overhead down? and what is the biggest project one can reasonably expect to build with Delphi? This tidbit won't help answering, but I think it might clarify what my boss is worried about, we currently start our program at about 18megs, normal working conditions are usually less than 40 megs, he thinks it could climb as high as 120 megs.

• Design pattern for client/server sessions?

  - by nonot1

  Are there any common patterns or general guidance I can learn from for how to design a client/server system where the both the client and server must maintain some kind per-client session state? I've found any number of libraries that can help with some of the plumbing, but it's the overall design I'm wondering about. Open issues in my mind: How to structure the client/server communication so that bidirectional synchronous and asynchronous requests are possible? The server side needs to spawn a couple of per-connected-client session-long helper process. How to manage that? How to manage the mapping from a given client (and any of it's requests) to server state and helper process instances in the face of multiple clients and intermittent network connectivity. Most communication can be simple blocking request/reply, but some will be long running processing tasks that the client will want to keep tabs on. To the extent that it matters, the platform is Linux/C/C++. Not web based. Just an existing thick-client software app being modified to talk to backend servers for some tasks.
