• Is it possible to run my Windows Form application in Windows CE platform?

  - by Fakhrul

  I am new in Windows CE development and never done it yet. Need some advise from the expert in here. In our current project, we are developing a client-server application. The client side is using a windows form application that are base on Windows XP OS while the server is a web base application. This question are related to the client application (Windows Form). This application are using Sql Server Express Edition for data storage. The data is stored in XML object format. It also can transfer a data from client to server via web service. It also interact with hardware such as Magnetic Stripe Reader, Contactless Smart Card Reader, and a thermal printer. Most of the communication between hardware device and systems are base on Serial Port. It is use standard app.config for the configuration and is a multi threaded application. There is a new requirement to use a Handheld device which is use a Windows CE platform. This handheld included the required equipment such as Contactless Smart Card Reader, Printer and Magnetic Stripe Reader. Instead of developing a new client application, is it possible to me to convert my current application that are base on Windows XP to Windows CE? If yes, how can I do that? If no, is it any other brilliant suggestion to do this? Thanks in advance. Software Engineer

• asp.net mvc - reusing pages/controllers in workflow

  - by fregas

  I have 2 workflows: 1) the user signs up for the first time. They see 3 different screens, their basic user information, their credit card, and some additional profile information. They complete these 3 steps in a wizard like fashion, where each time they hit "submit" they leave the current screen and move on to the next. 2) the user already is signed up. He has links in the navigation to these 3 seperate pages. He can update them in any order. When he hits save, he doesn't leave the page he's on, it just shows something at the top that says "Credit Card Info saved..." or whatever. Possibly using ajax or maybe a full page refresh. I would like to reuse the code not only the view but also in the controller for these 3 screens between the two workflows, but without a ton of if...then logic to determine where to go next depending on whether its a first signup in the wizard or updating individual parts of a profile. Any ideas?

  Create a DTD to record the sellers of merchandise to the Second-hand shop. Each seller has the child elements sellerID (in the format KSXXXXXXX), name, address, phone and sighted_identification. ? the name element has child elements of title and firstname and surname ? the address element has child elements address_line, suburb, state and postcode ? the sighted_identification can be any of the following – passport – drivers licence – birth certificate – Medicare card. –1.

Note 2: The shops database stores the sighted identification of sellers as p, dl, bc and mc rather than by their full name, so creating an entity for each type is required. Note 3: Your XSLT should order the sellers by sellerID – for this reason don’t have them ordered correctly in the XML file – rather sort the sellerID within the XSLT. OUTPUT SHOULD BE SOMETHING LIKE THIS SELLER ID : NAME: ADDRESS : PHONE : IDENTIFICATION : IDENTIFICATION : IDENTIFICATION :

• How to properly force a Blackberry Java application to install using Loader.exe

  - by Kevin White

  I want to include the Application Loader process in a software installation, to ensure that users get our software installed on their Blackberry by the time our installer software finishes. I know this is possible, because Aerize Card Loader (http://aerize.com/blackberry/software/loader/) does this. When you install their software, if your Blackberry is connected the Application Loader will come up and force the .COD file to install to the device. I can't make it work. Looking at RIM's own documentation, I need to: Place the ALX and COD files into a subfolder here: C:\Program Files\Common Files\Research In Motion\Shared\Applications\ Add a path to the ALX file in HKCU\Software\Research In Motion\Blackberry\Loader\Packages Index the application, by executing this at the command line: loader.exe /index Start the force load, by doing this: loader.exe /defaultUSB /forceload When I execute that last command, the Application Loader comes up and says that all applications are up to date and nothing needs to be done. If I execute loader.exe by double-clicking on it (or typing in the command with no parameters), I get the regular Application Loader wizard. It shows my program as listed, but un-checked. If I check it and click next, it will install to the Blackberry. (This is the part that I want to avoid, and that Aerize Card Loader's install process avoids.) What am I missing? It appears that the Aerize installer is doing something different but I haven't been able to ascertain what.

• Avoiding secondary selects or joins with Hibernate Criteria or HQL query

  - by Ben Benson

  I am having trouble optimizing Hibernate queries to avoid performing joins or secondary selects. When a Hibernate query is performed (criteria or hql), such as the following: return getSession().createQuery(("from GiftCard as card where card.recipientNotificationRequested=1").list(); ... and the where clause examines properties that do not require any joins with other tables... but Hibernate still performs a full join with other tables (or secondary selects depending on how I set the fetchMode). The object in question (GiftCard) has a couple ManyToOne associations that I would prefer to be lazily loaded in this case (but not necessarily all cases). I want a solution that I can control what is lazily loaded when I perform the query. Here's what the GiftCard Entity looks like: @Entity @Table(name = "giftCards") public class GiftCard implements Serializable { private static final long serialVersionUID = 1L; private String id_; private User buyer_; private boolean isRecipientNotificationRequested_; @Id public String getId() { return this.id_; } public void setId(String id) { this.id_ = id; } @ManyToOne @JoinColumn(name = "buyerUserId") @NotFound(action = NotFoundAction.IGNORE) public User getBuyer() { return this.buyer_; } public void setBuyer(User buyer) { this.buyer_ = buyer; } @Column(name="isRecipientNotificationRequested", nullable=false, columnDefinition="tinyint") public boolean isRecipientNotificationRequested() { return this.isRecipientNotificationRequested_; } public void setRecipientNotificationRequested(boolean isRecipientNotificationRequested) { this.isRecipientNotificationRequested_ = isRecipientNotificationRequested; } }

• magento payment process.. how it works in general

  - by spirytus

  hi everyone, got a question and I hope this is right place to ask :).. don’t quite understand how payment works in magento. client goes to checkout and lets say wants to pay as a guest, so provides address etc. and finally gets to payment methods. Then I want clients to pay thru credit card. Already have module installed for gateway (bank?) of my choice. At that point I would expect users to be redirected to 3rd party page (bank hosted) where they giving all the details, only after being returned to my magento site with appropriate message. In magento however it seems like they need to provide cc numbers and details on magento checkout page. I don’t understand if I (or the payment module I installed) need to transfer then all the credit card details to bank? I would have to have checkout page on ssl connection and static ip right? The thing is I want to avoid touching CC numbers at any point and would love to have it done by a bank page. I like the idea of magento interface all the way without redirecting to another page though, the only problem is not sure if would be able to set it all up properly. If anyone could explain to me possible options, what is the common way to do it and how the whole process works that would be very much appreciated. I did my research and looked all over google and various forums still need someones help though. Please let me know if some parts of my question are not quite clear, will try to better explain if necessary.

• Swimlane Diagram Softwares with Expand/Collapse Features

  - by louis xie

  I've been searching real hard for a software which can fulfill my needs, but to no avail. I have a swimlane diagram which is extremely huge, and almost impossible to model using Visio or any traditional swimlane software. I would need to model both the operational process, as well as the interactions within an application and between different applications. Therefore, without wasting additional effort modelling these separately, I am looking for a solution which I can combine both views together. That is, possibly one which I can expand/collapse/group/ungroup processes/subprocesses together. Take a typical credit card process for instance, a hypothetical description of the swimlane could be as such: Customer submits application form to the bank Bank Officer A receives the application form and validates that it was correctly filled Bank Officer A submits application form to Bank Officer B for processing. Bank Officer B checks credit quality of the customer through Application X. Application X submits query to Application Y to retrieve Credit Report. Application X retrieves credit report and submits to Application Z for computation of credit scores Bank Officer B validates that customer is credit worthy, and submits application to Bank Officer C for processing. The above is an over-simplified credit card request process, and a purely hypothetical one. What I'm trying to drive at is, each of the above processes have sub-processes, and I want to be able to switch between a "detailed" view and "aggregated" view. If possible, add in time dependency of the different tasks, as well. I haven't been able to find one such software which could do this.

• Best practice - logging events (general) and changes (database)

  - by b0x0rz

  need help with logging all activities on a site as well as database changes. requirements: * should be in database * should be easily searchable by initiator (user name / session id), event (activity type) and event parameters i can think of a database design but either it involves a lot of tables (one per event) so i can log each of the parameters of an event in a separate field OR it involves one table with generic fields (7 int numeric and 7 text types) and log everything in one table with event type field determining what parameter got written where (and hoping that i don't need more than 7 fields of a certain type, or 8 or 9 or whatever number i choose)... example of entries (the usual things): [username] login failed @datetime [username] login successful @datetime [username] changed password @datetime, estimated security of password [low/ok/high/perfect] @datetime [username] clicked result [result number] [result id] after searching for [search string] and got [number of results] @datetime [username] clicked result [result number] [result id] after searching for [search string] and got [number of results] @datetime [username] changed profile name from [old name] to [new name] @datetime [username] verified name with [credit card type] credit card @datetime datbase table [table name] purged of old entries @datetime via automated process etc... so anyone dealt with this before? any best practices / links you can share? i've seen it done with the generic solution mentioned above, but somehow that goes against what i learned from database design, but as you can see the sheer number of events that need to be trackable (each user will be able to see this info) is giving me headaches, BUT i do LOVE the one event per table solution more than the generic one. any thoughts? edit: also, is there maybe an authoritative list of such (likely) events somewhere? thnx stack overflow says: the question you're asking appears subjective and is likely to be closed. my answer: probably is subjective, but it is directly related to my issue i have with designing a database / writing my code, so i'd welcome any help. also i tried narrowing down the ideas to 2 so hopefully one of these will prevail, unless there already is an established solution for these kinds of things.

• API-based solutions for sending payments to people without bank accounts

  - by Tauren

  I'm looking for inexpensive ways to send payments to hundreds or thousands of individual contractors, even if they do not have a bank account. Currently I only need to support payment in the USA, but may eventually be international. Here's the scenario: I offer a service that allows an organization or manager-type person to coordinate contractors for very short term jobs. These jobs are typically only an hour or two in length. A contractor may get only one job over an entire month, several jobs spread out over a month, multiple jobs on a single day, or any other combination. Thus, a single contractor could earn as little as one job's payment up to potentially payment for dozens. Payment for a month could be as little as $10 up to $1000's. Right now, the system provides payroll reports to the manager and it is the manager's responsibility to produce checks, stuff envelopes, and send mail via the US postal service. I'd like to remove this burden from the manager and have all the payments taken care of for them automatically by the system. I'm not sure where to start or what the best options would be. I'm starting to look into the following solutions, but don't know specifics yet and would like some advice before pursuing them. I'd also like to hear about other ideas or suggestions. PayPal (Send Money, Adaptive Payments, x.com, other???) Amazon (Flexible Payments System?) Fund some sort of pre-paid debit card? Web service with API that mails checks for you? Direct deposit via a bank API (for users with bank accounts)? The problem is that many of these contractors may not be able to obtain bank accounts or credit cards within the USA. I don't mind doing a hybrid of solutions, but are there any that would work well with this issue? I want the solution to be easy to use for the contractors, meaning that they can get the money easily (via check in the mail, debit card ATM withdrawal, etc.)

• How can I lookup data about a book from its barcode number?

  - by Joel Spolsky

  I'm building the world's simplest library application. All I want to be able to do is scan in a book's UPC (barcode) using a typical scanner (which just types the numbers of the barcode into a field) and then use it to look up data about the book... at a minimum, title, author, year published, and either the Dewey Decimal or Library of Congress catalog number. The goal is to print out a tiny sticker ("spine label") with the card catalog number that I can stick on the spine of the book, and then I can sort the books by card catalog number on the shelves in our company library. That way books on similar subjects will tend to be near each other, for example, if you know you're looking for a book about accounting, all you have to do is find SOME book about accounting and you'll see the other half dozen that we have right next to it which makes it convenient to browse the library. There seem to be lots of web APIs to do this, including Amazon and the Library of Congress. But those are all extremely confusing to me. What I really just want is a single higher level function that takes a UPC barcode number and returns some basic data about the book.

• Javascript not working in firefox

  - by Samuel Meddows

  Hi guys, I have a PHP form validation function that I developed in chrome and now will not work in firefox or Opera. The function checks to see if a section of the form is blank and shows and error message. If there is no error then then the form submits through document.events.submit(); CODE: function submit_events() { //Check to see if a number is entered if the corosponding textbox is checked if (document.events.dj_card.checked == true && dj_amount.value==""){ //Error Control Method //alert ('You didn\'t enetr an Amount for DJ\'s Card!'); var txt=document.getElementById("error") txt.innerHTML="<p><font color=\"#FF0000\"> You didn\'t enetr an Amount for DJ\'s Card!</font></p>"; window.document.getElementById("dj_card_label").style.color = '#FF0000'; //Reset window.document.getElementById("company_amount_label").style.color = '#000000'; window.document.getElementById("own_amount_label").style.color = '#000000'; }else{ document.events.submit(); } The document.events.submit();does work across all my browsers however the check statements do not. If the box is not ticked the form submits. If the box is ticked it does not matter whether there is data in the dj_amount.value or not. The form will not submit and no error messages are displayed. Thanks guys.

• ecommerce platform or from scratch? customer specific catalogs and purchase orders

  - by rafi

  I have a possible freelance job in front of me for a distributor who wants product ordering set up but the orders are all P.O.s basically - no actual credit card or paypal transaction. The customer is simply billed and the order archived. Customers will need to login to this site and each customer will have their own custom catalog of a few dozen products which have been setup via a control panel this distributor uses. So there will be a master catalog of over 1,000 products (perhaps browsable but not to be ordered from on the site) but each customer will only be able to order from the products specified for their accounts. I know I can build this from scratch but I figured it's worth looking into what ecommerce platforms would get me a nice head start. Obviously shopping cart, order history, catalog management are concepts that I can reuse but are any of the ecommerce systems out there also capable of handling custom catalogs (maybe as multi-stores?) or transactions billed to accounts without credit card? The more I could reuse the better. I've messed with OSCommerce (way back) and a little Zen Cart more recently. I've also worked on a number of totally custom e-commerce sites. But my knowledge of the open source e-commerce tools is pretty limited and I'm trying to keep the effort as simple as I possibly can on this. I'm pretty flexible on the language of the platform by the way. Thanks in advance.

• Creating many polygons with OpenGL is slow?

  - by user146780

  I want to draw many polygons to the screen but i'm quickly noticing that it slows down quickly. As a test I did this: for(int i = 0; i < 50; ++i) { glBegin( GL_POLYGON); glColor3f( 0.0f, 1, 0.0f ); glVertex2f( 500.0 + frameGL.GetCameraX(), 0.0f + frameGL.GetCameraY()); glColor3f( 0.0f, 1.0f, 0.0f ); glVertex2f( 900.0 + frameGL.GetCameraX(), 0.0f + frameGL.GetCameraY()); glColor3f( 0.0f, 0.0f, 0.5 ); glVertex2f(900.0 + frameGL.GetCameraX(), 500.0f + frameGL.GetCameraY() + (150)); glColor3f( 0.0f, 1.0f, 0.0f ); glVertex2f( 500 + frameGL.GetCameraX(), 500.0f + frameGL.GetCameraY()); glColor3f( 1.0f, 1.0f, 0.0f ); glVertex2f( 300 + frameGL.GetCameraX(), 200.0f + frameGL.GetCameraY()); glEnd(); } This is only 50 polygons and already it's gtting slow. I can't upload them directly to the card because my program will allow the user to reshape the verticies. My question is, how can I speed this up. I'm not using depth. I also know it's not my GetCamera() functions because if I create 500,000 polygons spread apart t's fine, it just has trouble showing them in the view. If a graphics card can support 500,000,000 on screen polygons per second, this should be easy right? Thanks

• How to pass a value from the Jquery validation

  How can i pass a value from the jquery validation. I have an input box named clubCardNumber it should validate the length of the inputted value. If the length is equal to 10 the value passes to the hidden field named else validated it if its null or empty if all validations are true then its a clubCard. Here is how i implemented it on Javascript function validateClubCardNumber() { var varClubCardNumber = $('#clubCardNumber').val(); $('#phoneNumber').val(""); var returnVal = true; if ((null == varClubCardNumber || '' == trim(varClubCardNumber)){ return false; } if( varClubCardNumber.length < 10 ){ return false; }else if( varClubCardNumber.length == 10 ) { //The Phone Number field should contains numbers only var pattern = /^[0-9 -]*$/ ; var flag = pattern.test(trim(varClubCardNumber)); if(flag == false){ return false; }else{ $('#phoneNumber').val(varClubCardNumber); returnVal = true; } } } return returnVal; } HTML <div > <label for="clubCardNumber" >Card or Phone Number:</label> <input id="clubCardNumber" name="clubCardNumber" type="text" placeholder="Card or Phone Number" value="" maxlength="20"/> </div> <input type="hidden" id="phoneNumber" name="phoneNumber" value=""/>

• Adding with PHP to a MySQL database

  - by shinjuo

  I am pretty new to PHP and I am trying to make an inventory database. I have been trying to make it so that a user can enter a card ID and then amount the want to add to the inventory and have it update the inventory. For example someone could type in test and 2342 and it would update test. Here is what I have been trying with no success: add.html <body> <form action="add.php" method="post"> Card ID: <input type="text" name="CardID" /> Amount to Add: <input type="text" name="Add" /> <input type="submit" /> </form> </body> </html> add.php <?php $link = mysql_connect('tulsadir.ipowermysql.com', 'cbouwkamp', '!starman1'); if (!$link){ die('Could not connect: ' . mysql_error()); } mysql_select_db("tdm_inventory", $link); $add = $_POST[Add] mysql_query("UPDATE cardLists SET AmountLeft = '$add' WHERE cardID = 'Test'"); echo "test successful"; mysql_close($link); ?>

• How do I convert a simple ruby flashcard program into a ROR app?

  - by Mark Wilbur

  What I'm trying to do is make a basic flashcard app on rails. At this point, all I'm looking for is the functionality to iterate through a list of flashcards, quiz the user and let the user know if they were right or not. In ruby, it didn't take me long to write: class Card attr_accessor :answer, :question def initialize(answer = "", question="") @answer = answer @question = question end def quiz puts "What does #@question mean?" answer = gets.chomp if answer == @answer puts "Right" return true else puts "Wrong" return answer end end end class Cardlist attr_accessor :Cards def initialize(Cards = []) @Cards = Cards end def quiz Cards.each do |w| w.quiz end end end The problem I'm having with rails is figuring out where to put the logic to loop through all the cards in the list. I've made models specifying that Card belongs_to cardlist and that Cardlist has_many cards. I know application logic should go in the controller, but if I were to make a "quiz" action for my Cardlist controller, how would I make it iterate through all the cards? After each "quiz" page generated, I'd need to get an answer back from the user, respond (maybe flash) whether it was right or not and then continue onto the next question. Would any of that logic have to go into the view in order to make sure it's sending back the user inputted answers to the controller?

• Select multi-select form from array

  - by Budove

  Here's the issue. I have a database column called pymnt_meth_pref, which contains a comma separated string of payment methods chosen from a multiselect form. <td>Payment Methods Used:<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Cash">I can pay with cash.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Check">I can pay by check.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Credit Card">I can pay by credit card.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Paypal">I can pay with Paypal.<br /> </td> This array is posted to a variable and turned into a comma separated string if (isset($_POST['pyment_meth_pref'])) $pymntmethpref = implode(", ", $_POST['pyment_meth_pref']); if (isset($_POST['pyment_meth_acc'])) $pymntmethacc = implode(", ", $_POST['pyment_meth_acc']); This is then inserted into the database as a comma separated string. What I would like to do, is take this string and apply the values to the original form when the user goes back to the form as 'pre-selected' checkboxes, indicated that the user has already selected those values previously, and keeping those values in the database if they choose to edit any other information in the form. I'm assuming this would need to be done with javascript but if there is a way to do it with PHP I'd rather do it that way.

• To display the images in mobile devices is it necessary that the images should resides on device in

  - by Shailesh Jaiswal

  I am devloping smart device application in C#. In this application I have some images in my application which I used to dispay on emulator from my application. To display the images on emulator I need to create the one folder of images which resides on the emulator. Only after that I am able to display the images in emulator. I am able to create the folder in emulator by using File-Configure-General-Shared Folder. For sharing the folder I am giving the path of the folder which contains the images. Once I share the folder the folder of images which resides in my application will get copied in emulator with the name "Storage Card". Now I need to use the path as Bitmap bmp=new Bitmap(@"/Storage Card/ImageName.jpg"); Now I am able to display the images in emulator. Can we display the images in the emulator without any image folder which resides on emultor (so that we dont need to place the image folder in emulator as in the above case by sharing the folder) ? If the answere is no then to run the application on different mobile devices we need to place the folder which contains the images on different mobile devices. Isnt it? If the answere is yes then how we can display the images on different mobile device from our application without placing any folder of images on mobile devices?

• Reusing named_scope to define another named_scope

  - by Sergei Kozlov

  The problem essence as I see it One day, if I'm not mistaken, I have seen an example of reusing a named_scope to define another named_scope. Something like this (can't remember the exact syntax, but that's exactly my question): named_scope :billable, :conditions => ... named_scope :billable_by_tom, :conditions => { :billable => true, :user => User.find_by_name('Tom') } The question is: what is the exact syntax, if it's possible at all? I can't find it back, and Google was of no help either. Some explanations Why I actually want it, is that I'm using Searchlogic to define a complex search, which can result in an expression like this: Card.user_group_managers_salary_greater_than(100) But it's too long to be put everywhere. Because, as far as I know, Searchlogic simply defines named_scopes on the fly, I would like to set a named_scope on the Card class like this: named_scope from_big_guys, { user_group_managers_salary_greater_than(100) } - this is where I would use that long Searchlogic method inside my named_scope. But, again, what would be the syntax? Can't figure it out. Resume So, is named_scope nesting (and I do not mean chaining) actually possible?

• How to "End Task" not "Kill" or "Terminate"?

  - by Luiscencio

  Hi community. I have a 3G card to provide internet to a remote computer... I have to run a program(provided with the card) to establish the connection... since connections suddenly is lost I wrote a script that Kills the program and reopens it so that the connection is reestablished, there are certain versions of this program that don't kill the connection when killed/terminated, just when closed properly. so I am looking for a script or program that "Properly Closes" a window so I can close it and reopen it in case the connection is lost. this is the code that kills the program Option Explicit Dim objWMIService, objProcess, colProcess Dim strComputer, strProcessKill strComputer = "." strProcessKill = "'Telcel3G.exe'" Set objWMIService = GetObject("winmgmts:" _ & "{impersonationLevel=impersonate}!\\" _ & strComputer & "\root\cimv2") Set colProcess = objWMIService.ExecQuery _ ("Select * from Win32_Process Where Name = " & strProcessKill ) For Each objProcess in colProcess objProcess.Terminate() Next WSCript.Echo "Just killed process " & strProcessKill _ & " on " & strComputer WScript.Quit

• In Gtk#, why might VALID_ITER fail even after I check it with IterIsValid?

  - by Matthew

  I have a convenience function in my TreeView that looks something like this: Card GetCardFromPath (TreePath path) { TreeIter iter; if (path == null || !Model.GetIter (out iter, path)) return null; if ((Model as TreeModelSort).IterIsValid (iter)) return (Card) Model.GetValue (iter, 0); return null; } Most of the time this works without any errors. But when it is called directly after the Model is changed, line 8 gives me these Gtk runtime errors: [Fatal 16:53:02.448] [Gtk] gtk_list_store_get_value: assertion `VALID_ITER (iter, list_store)' failed [Fatal 16:53:02.449] [GLib-GObject] g_value_unset: assertion `G_IS_VALUE (value)' failed As far as I can tell, I shouldn't even need to check IterIsValid, because I'm already checking the return value of Model.GetIter. Even so, how can VALID_ITER fail in a function that only gets called if IterIsValid returns true? If it makes a difference, the Model is a TreeModelSort, which sorts a TreeModelFilter, which filters a ListStore. The error occurs when GetCardFromPath is called from HandleSelectionChanged when multiple rows have just been removed from the ListStore. It doesn't seem to prevent anything from working properly, but having a cascade of errors whenever I remove multiple rows isn't really ideal.

• Build OpenGL model in parallel?

  - by Brendan Long

  I have a program which draws some terrain and simulates water flowing over it (in a cheap and easy way). Updating the water was easy to parallelize using OpenMP, so I can do ~50 updates per second. The problem is that even with a small amounts of water, my draws per second are very very low (starts at 5 and drops to around 2 once there's a significant amount of water). It's not a problem with the video card because the terrain is more complicated and gets drawn so quickly that boost::timer tells me that I get infinity draws per second if I turn the water off. It may be related to memory bandwidth though (since I assume the model stays on the card and doesn't have to be transfered every time). What I'm concerned about is that on every draw, I'm calling glVertex3f() about a million times (max size is 450*600, 4 vertices each), and it's done entirely sequentially because Glut won't let me call anything in parallel. So.. is if there's some way of building the list in parallel and then passing it to OpenGL all at once? Or some other way of making it draw this faster? Am I using the wrong method (besides the obvious "use less vertices")?

• Intel 1.83 Mac Mini upgraded to 1.5 gig for Snow Leopard

  - by Paula

  Even though I've upgraded countless video cards, RAM, harddrives, motherboards in PCs... this will be my first mac mini RAM upgrade. I've watched the classic "putty knife" video. (Absurd method... but I guess it's what I'm stuck with.) I have a 1.83 Intel-based Mac Mini from 2007-2008, with 1 gig of RAM. (Two 512 sticks) Can I install 1 gig + 512 ? (Or do I have to throw away my existing sticks and buy two 1 gig sticks?) This old machine is rarely used... so I want to spend the absolute minimum on this RAM upgrade. We ONLY use it to run xCode... nothing more. But wanted to increase the RAM so we can install Snow Leopard. I have no idea how many pins the memory has. I printed out over FORTY pages of specs about this machine from "About this Mac"... but didn't find what I needed. Does this sound right: DDR2 SDRAM (but no mention of SO-DIMM) 667MHZ (but don't know if I can use faster also) Pin count: Unknown Computer model number: Unknown (But I "think" it's an MB138/A) PC2 RAM (unknown... not mentioned) 5300 (unknown... not mentioned) Mfg date: (unknown... not mentioned) Number of slots: (unknown... not mentioned) Laptop or desktop RAM: (unknown... not mentioned)

• eMachine W5243 won't POST; fans run but optical drive will not open.

  - by NicciAdonai

  Symptoms are what is described in the title. The machine reacts to the power button being hit by spinning up the two fans: CPU and PSU. The hard drive (SATA) spins up as well. No other reaction. This one symptom is particularly weird, though: the optical drive will not open with the IDE cable attached, but if I unplug it from the mobo it will. I can turn the PC on with it attached, won't open; then unplug IDE while it is still on, WILL open; then plug IDE back in with the PC STILL ON, WON'T open. I have disconnected every peripheral unnecessary to POST. These include: mouse/keyboard, PCI modem, the IDE optical drive (power and data), and the SATA HDD (power and data). Video is onboard. The only two things connected are DB15 video and power cable. There were 2 512 MB DDR2 sticks of RAM in it. I have tried running it with just one of them, then switched the other in. Currently seated is a completely different 1 GB stick that I keep around for troubleshooting purposes, and I have tried it in both slots. I have replaced the CMOS battery with a used one I had lying around, and which worked in the computer it came out of. I have tested the PSU with a tester to confirm it was good, then tried connecting another PSU just in case--same symptoms. I have even tried a suggestion I found elsewhere on this site wherein one disconnects power from the PSU and then presses the PC's power button twice, thereby "resetting" the PSU. Currently I am trying yet another suggestion: turn it on and wait an inordinate amount of time for POST. Any help would be appreciated.
