  • Does data mining qualify as an abuse?

    - by Hybryd
    Hi all, today I had a strange experience with my ISP. They disabled my password for internet connection, and when I called them, they enabled it again, but they didn't say why it happened. In the last couple of days I was running a data mining that I made for one forum to get some useful info about business that I'm in. So I thought, maybe my ISP figured that 10,000 page requests in couple of hours to the same site may be some kind of attack. What do you think, does it qualify as an attack? Is it even ok to data mine in that way?

  • Excel data range - to sum series within date range

    - by Mark
    I have a set of data that I would like to manipulate but my problem is not straight forward. In this data I have date ranges that include multiple entries of the same date on some days and not on others. What I need to accomplish is to manage a trading account so that no more than 1% of the account is put at risk on any given day (retrospectively). To do this, when a series of trades falls on the same day, I need to total the risk associated with each of those trades so that I can limit the total risk of the combined trades by limiting the position size I take in each. Here is a sample set of the data I am working with. As you can see, there are 5 trades on Jan 3. Each of these trades comes with a risk value. I need to add the risk values of these 5 trades so that I can compare it to an account value and then determine if I should take more than 1 position in each trade. As you can see there are different numbers of trades that occur on the 4th, 5th 6th and 9th. I need the values returned in each row so that I can further manipulate them in the spreadsheet. I am not new to Excel, but cannot come up with a solution here - your input is much appreciated. Forgive the presentation below - I cannot upload a pic (new user) and the format does not carry across from excel. I have aligned the first several lines manually. Thx. Date .............

  • URGENT: help recovering lost data

    - by Niels Kristian
    I have made a directory: sudo mkdir /ssd, the directory was supposed to be mounted to a raid array called md3. This was done by adding /dev/md3 /ssd auto defaults 0 0 to fstab. Then after a while where I had used the directory, I realized that I had forgotten to run sudo mount -a - and then I did, and now the data is gone. I tried to uncomment the line in fstab and run sudo mount -a but that didn't get back my data. What can I do!? CONTENT OF FSTAB: proc /proc proc defaults 0 0 none /dev/pts devpts gid=5,mode=620 0 0 /dev/md/0 none swap sw 0 0 /dev/md/1 /boot ext3 defaults 0 0 /dev/md/2 / ext4 defaults 0 0 /dev/md3 /ssd auto defaults 0 0

  • Recover data from SD card

    - by Paul Tarjan
    I have a 2GB kingston microSD card which is about 3 years old. I put it in a reader today in my Windows Vista computer, wrote a 32MB file onto it, safely removed it, and then tried to read it elsewhere. Nothing. Putting it back in vista it now says You need to format the disk in drive F: before you can use it. What should I do? I have access to many computers and OSes if your recommendations need that. I would be very sad if I lost all the contents of the card. Most of the data is backed up, but there are a few things that aren't. :( Doing a # dd if=/dev/sdg of=~/tmp/sd.bin gives me a 2 gig file, and grepping the file it seems like lots of my data is still there, how can I put it back together?

  • How to have Excel data validation display different data in drop down than is actually validated

    - by Memitim
    How can I provide a user with a drop-down menu in a cell that displays the contents from one column but actually writes the value from a different column to the cell and validates against the values from that second column? I have a bit of code that very nearly does this (credit: DV0005 from the Contextures site): Private Sub Worksheet_Change(ByVal Target As range) On Error GoTo errHandler If Target.Cells.Count > 1 Then GoTo exitHandler If Target.Column = 10 Then If Target.Value = "" Then GoTo exitHandler Application.EnableEvents = False Target.Value = Worksheets("Measures").range("B1") _ .Offset(Application.WorksheetFunction _ .Match(Target.Value, Worksheets("Measures").range("Measures"), 0) - 1, 1) End If The drop-down displays the values from one column, for example Column B, but when selected actually writes the value on the same row from Column C to the cell. However, data validation is actually validating against Column B, so if I manually enter something from Column C in the cell and try to move to another cell, data validation throws an error.

  • Recovering data from a corrupted disk

    - by r_honey
    I use an external harddisk to backup my data (it had 3 partitions). Last week when I plugged it in, the OS (Win 7) hung up and I had to force re-boot the machine. When I turned it back on, the system just did not detect the hard-disk. It was last Sunday and I had to give up after sometime. Now I return back next Sunday (today) and when I plug it back-in to the machine, the OS detects the disk as well as all the 3 partitions on it. But it says all 3 are unformatted and I cant access any of them. Is there any way to recover data from the 3 partitions (I tried PC File Recovery and Recuva from PiriForm but neither detected these partitions).

  • TestDriven.Net 3.0 – All Systems Go

    - by Jamie Cansdale
    I’m pleased to announce that TestDriven.Net 3.0 is now available. Finally! I know many of you will already be using the Beta and RC versions, but if you look at the release notes you’ll see there’s been many refinements since then, so I highly recommend you install the RTM version. Here is a quick summary of a few new features: Visual Studio 2010 supports targeting multiple versions of the .NET framework (multi-targeting). This means you can easily upgrade your Visual Studio 2005/2008 solutions without necessarily converting them to use .NET 4.0. TestDriven.Net will execute your tests using the .NET version your test project is targeting (see ‘Properties > Application > Target framework’). There is now first class support for MSTest when using Visual Studio 2008 & 2010. Previous versions of TestDriven.Net had support for a limited number of MSTest attributes. This version supports virtually all MSTest unit testing related attributes, including support for deployment item and data driven test attributes. You should also find this test runner is quick. ;) There is a new ‘Go To Test/Code’ command on the code context menu. You can think of this as Ctrl-Tab for test driven developers; it will quickly flip back and forth between your tests and code under test. I recommend assigning a keyboard shortcut to the ‘TestDriven.NET.GoToTestOrCode’ command. NCover can now be used for code coverage on .NET 4.0. This is only officially supported since NCover 3.2 (your mileage may vary if you’re using the 1.5.8 version). Rather than clutter the ‘Output’ window, ignored or skipped tests will be placed on the ‘Task List’. You can double-click on these items to navigate to the offending test (or assign a keyboard shortcut to ‘View.NextTask’). If you’re using a Team, Premium or Ultimate edition of Visual Studio 2005-2010, a new ‘Test With > Performance’ command will be available. This command will perform instrumented performance profiling on your target code. A particular focus of this version has been to make it more keyboard friendly. Here’s a list of commands you will probably want to assign keyboard shortcuts to: Name Default What I use TestDriven.NET.RunTests Run tests in context   Alt + T TestDriven.NET.RerunTests Repeat test run   Alt + R TestDriven.NET.GoToTestOrCode Flip between tests and code   Alt + G TestDriven.NET.Debugger Run tests with debugger   Alt + D View.Output Show the ‘Output’ window Ctrl+ Alt + O   Edit.BreakLine Edit code in stack trace Enter   View.NextError Jump to next failed test Ctrl + Shift + F12   View.NextTask Jump to next skipped test   Alt + S   By default the ‘Output’ window will automatically activate when there is test output or a failed test (this is an option). The cursor will be positioned on the stack trace of the last failed test, ready for you to hit ‘Enter’ to jump to the fail point or ‘Esc’ to return to your source (assuming your ‘Output’ window is set to auto-hide).  If your ‘Output’ window isn’t set to auto-hide, you’ll need to hit ‘Ctrl + Alt + O’ then ‘Enter’. Alternatively you can use ‘Ctrl + Shift + F12’ (View.NextError) to navigate between all failed tests.   For more frequent updates or to give feedback, you can find me on twitter here. I hope you enjoy this version. Let me know how you get on. :)

It simulates a complete environment where a population of terminal operators executes transactions against a database. The benchmark is centered around the principal activities (transactions) of an order-entry environment. These transactions include entering and delivering orders, recording payments, checking the status of orders, and monitoring the level of stock at the warehouses. Key Points and Best Practices Oracle Database 11g Release 2 Enterprise Edition with Partitioning scales easily to this high level of performance. COMSTAR (Common Multiprotocol SCSI Target) is the software framework that enables an Oracle Solaris host to serve as a SCSI Target platform. COMSTAR uses a modular approach to break the huge task of handling all the different pieces in a SCSI target subsystem into independent functional modules which are glued together by the SCSI Target Mode Framework (STMF). The modules implementing functionality at SCSI level (disk, tape, medium changer etc.) are not required to know about the underlying transport. And the modules implementing the transport protocol (FC, iSCSI, etc.) are not aware of the SCSI-level functionality of the packets they are transporting. The framework hides the details of allocation providing execution context and cleanup of SCSI commands and associated resources and simplifies the task of writing the SCSI or transport modules. Oracle iPlanet Web Server middleware is used for the client tier of the benchmark. Each web server instance supports more than a quarter-million users while satisfying the response time requirement from the TPC-C benchmark.

  • Data migration - dangerous or essential?

    - by MRalwasser
    The software development department of my company is facing with the problem that data migrations are considered as potentially dangerous, especially for my managers. The background is that our customers are using a large amount of data with poor quality. The reasons for this is only partially related to our software quality, but rather to the history of the data: Most of them have been migrated from predecessor systems, some bugs caused (mostly business) inconsistencies in the data records or misentries by accident on the customer's side (which our software allowed by error). The most important counter-arguments from my managers are that faulty data may turn into even worse data, the data troubles may awake some managers at the customer and some processes on the customer's side may not work anymore because their processes somewhat adapted to our system. Personally, I consider data migrations as an integral part of the software development and that data migration can been seen to data what refactoring is to code. I think that data migration is an essential for creating software that evolves. Without it, we would have to create painful software which somewhat works around a bad data structure. I am asking you: What are your thoughts to data migration, especially for the real life cases and not only from a developer's perspecticve? Do you have any arguments against my managers opinions? How does your company deal with data migrations and the difficulties caused by them? Any other interesting thoughts which belongs to this topics?

  • Data binding in web UI frameworks, what's the deal?

    - by c-smile
    I believe that most of modern Web frameworks that pretend to be MVC ones also has a notion of data binding in one form or another. Examples: AngularJS, EmberJS, KnockoutJS, etc. I am assuming that "data binding" is a declarative definition (oxymoron, no?) of live link between data (a.k.a. model) and its representation (a.k.a. view). With some transformers in between (a.k.a. controllers). I understand why declarativeness is kind of appealing but also understand that as usual it comes with the price. In particular: 1. Live binding is quite heavy, either with dirty watch (high CPU consumption) or with Object.observe() (high memory consumption with high CPU load in some scenarios). 2. There is a "frame" part in the framework word, means there are some boundaries/limits that can be hard to overcome if you need slightly more than it was designed for. Quite usual time split: 90% of features are made in 10% of project time. But 10% rest take 90% of project time. I suspect (a.k.a. educated guess) that those MVC things are not helping to implement more functionality in less time... If so their usage motivation is not quite clear. As an example: last week wanted to find virtual list idea/solution. Found one in vanilla JavaScript that is 120 LOC. Implementation of the same but in AngualrJS is about 420 LOC. Most of the code there seems like a fight with the framework itself... So is my question: what benefits that MVC stuff or data binding give us? Is it just a buzzword popular among project managers or they give us something useful. If later one then what exactly?

  • How to manipulate *huge* amounts of data

    - by Alejandro
    Hi there! I'm having the following problem. I need to store huge amounts of information (~32 GB) and be able to manipulate it as fast as possible. I'm wondering what's the best way to do it (combinations of programming language + OS + whatever you think its important). The structure of the information I'm using is a 4D array (NxNxNxN) of double-precission floats (8 bytes). Right now my solution is to slice the 4D array into 2D arrays and store them in separate files in the HDD of my computer. This is really slow and the manipulation of the data is unbearable, so this is no solution at all! I'm thinking on moving into a Supercomputing facility in my country and store all the information in the RAM, but I'm not sure how to implement an application to take advantage of it (I'm not a professional programmer, so any book/reference will help me a lot). An alternative solution I'm thinking on is to buy a dedicated server with lots of RAM, but I don't know for sure if that will solve the problem. So right now my ignorance doesn't let me choose the best way to proceed. What would you do if you were in this situation? I'm open to any idea. Thanks in advance!

  • Integrating Oracle Hyperion Smart View Data Queries with MS Word and Power Point

    - by Andreea Vaduva
    Untitled Document table { border: thin solid; } Most Smart View users probably appreciate that they can use just one add-in to access data from the different sources they might work with, like Oracle Essbase, Oracle Hyperion Planning, Oracle Hyperion Financial Management and others. But not all of them are aware of the options to integrate data analyses not only in Excel, but also in MS Word or Power Point. While in the past, copying and pasting single numbers or tables from a recent analysis in Excel made the pasted content a static snapshot, copying so called Data Points now creates dynamic, updateable references to the data source. It also provides additional nice features, which can make life easier and less stressful for Smart View users. So, how does this option work: after building an ad-hoc analysis with Smart View as usual in an Excel worksheet, any area including data cells/numbers from the database can be highlighted in order to copy data points - even single data cells only.   TIP It is not necessary to highlight and copy the row or column descriptions   Next from the Smart View ribbon select Copy Data Point. Then transfer to the Word or Power Point document into which the selected content should be copied. Note that in these Office programs you will find a menu item Smart View;from it select the Paste Data Point icon. The copied details from the Excel report will be pasted, but showing #NEED_REFRESH in the data cells instead of the original numbers. =After clicking the Refresh icon on the Smart View menu the data will be retrieved and displayed. (Maybe at that moment a login window pops up and you need to provide your credentials.) It works in the same way if you just copy one single number without any row or column descriptions, for example in order to incorporate it into a continuous text: Before refresh: After refresh: From now on for any subsequent updates of the data shown in your documents you only need to refresh data by clicking the Refresh button on the Smart View menu, without copying and pasting the context or content again. As you might realize, trying out this feature on your own, there won’t be any Point of View shown in the Office document. Also you have seen in the example, where only a single data cell was copied, that there aren’t any member names or row/column descriptions copied, which are usually required in an ad-hoc report in order to exactly define where data comes from or how data is queried from the source. Well, these definitions are not visible, but they are transferred to the Word or Power Point document as well. They are stored in the background for each individual data cell copied and can be made visible by double-clicking the data cell as shown in the following screen shot (but which is taken from another context).   So for each cell/number the complete connection information is stored along with the exact member/cell intersection from the database. And that’s not all: you have the chance now to exchange the members originally selected in the Point of View (POV) in the Excel report. Remember, at that time we had the following selection:   By selecting the Manage POV option from the Smart View meny in Word or Power Point…   … the following POV Manager – Queries window opens:   You can now change your selection for each dimension from the original POV by either double-clicking the dimension member in the lower right box under POV: or by selecting the Member Selector icon on the top right hand side of the window. After confirming your changes you need to refresh your document again. Be aware, that this will update all (!) numbers taken from one and the same original Excel sheet, even if they appear in different locations in your Office document, reflecting your recent changes in the POV. TIP Build your original report already in a way that dimensions you might want to change from within Word or Power Point are placed in the POV. And there is another really nice feature I wouldn’t like to miss mentioning: Using Dynamic Data Points in the way described above, you will never miss or need to search again for your original Excel sheet from which values were taken and copied as data points into an Office document. Because from even only one single data cell Smart View is able to recreate the entire original report content with just a few clicks: Select one of the numbers from within your Word or Power Point document by double-clicking.   Then select the Visualize in Excel option from the Smart View menu. Excel will open and Smart View will rebuild the entire original report, including POV settings, and retrieve all data from the most recent actual state of the database. (It might be necessary to provide your credentials before data is displayed.) However, in order to make this work, an active online connection to your databases on the server is necessary and at least read access to the retrieved data. But apart from this, your newly built Excel report is fully functional for ad-hoc analysis and can be used in the common way for drilling, pivoting and all the other known functions and features. So far about embedding Dynamic Data Points into Office documents and linking them back into Excel worksheets. You can apply this in the described way with ad-hoc analyses directly on Essbase databases or using Hyperion Planning and Hyperion Financial Management ad-hoc web forms. If you are also interested in other new features and smart enhancements in Essbase or Hyperion Planning stay tuned for coming articles or check our training courses and web presentations. You can find general information about offerings for the Essbase and Planning curriculum or other Oracle-Hyperion products here (please make sure to select your country/region at the top of this page) or in the OU Learning paths section , where Planning, Essbase and other Hyperion products can be found under the Fusion Middleware heading (again, please select the right country/region).

  • Comparison of Code Review Tools/Systems

    - by SytS
    There are a number of tools/systems available aimed at streamlining and enhancing the code review process, including: CodeStriker Review Board, code review system in use at VMWare Code Collaborator, commercial product by SmartBear Rietveld, based on Modrian, the code review system in use at Google Crucible, commercial product by Atlassian These systems all have varying feature sets, and differ in degrees of maturity and polish; the selection is a little bewildering for someone who is evaluating code review systems for the frist time. Some of these tools have already been mentioned in other questions/answers on StackOverflow, but I would like to see a more comprehensive comparison of the more popular systems, especially with respect to: integration with source control systems integration with bug tracking systems supported workflow (reviews pre/post commit, review or contiguous/non-contigous revision ranges, etc) deployment/maintenance requirements

  • Suggestion for a Data Structure!

    - by Jay
    I have the following requirements for a data structure: Direct access to an element with the help of a key (Key will be an integer, range is also same as integer range) Avoid memory allocation in chunks (Allocate contigous memory for the data structure including the data) Should be able to grow the data structure size dynamically Which data structure would you suggest? Any pointers in the direction will also be of help.

  • How can Core Data store an NSData?

    - by mystify
    The documentation says, that core data properties can only store NSString, NSNumber and NSDate types. However, a lot of Core Data users claim Core Data could also store an NSData type. But I wasn't able to see that in the documentation, although the Xcode Data Modeler allows to choose a data type called "binary" (which seems to be NSData). Did I miss something? Is there a hidden place in the documentation that indeed lists NSData for binary stuff?

  • Finding easily parseable chemical element data

    - by nickname
    I am writing an application that needs simple data found (mostly) on the periodic table of elements, such as atomic mass, atomic number, state, etc. However, I would prefer not to manually enter this data. I managed to find the NIST website (http://www.nist.gov/pml/data/edi.cfm) with all of the data I need, but not in a downloadable format. Where can I find this data? Preferably, it would be in an XML/YAML/JSON/other documented format, however, any format would be helpful.

  • C# - Fast and simple multi dimensional data structures?

    - by Jeremy Rudd
    I need to store multi-dimensional data consisting of numbers in a manner thats easy to work with. I'm capturing data in real time, and once processed I would destroy and GC older data. This data structure must be fast so it won't hit my overall app performance. The faster the better. What are my choices in terms of platform supported data structures? I'm using VS 2010. and .NET 4.

  • New article available in "SOA Suite Essentials for WLI Users" series: Dynamic Data Lookup in a Busin

    - by simone.geib
    It is my pleasure to announce the publishing of another article in our "SOA Suite Essentials for WLI Users" series: "Dynamic Data Lookup in a Business Process: Meta Data Cache Control in Oracle WebLogic Integration and Domain Value Maps in SOA Suite". This article explains how dynamic data can be retrieved in a business process using Domain Value Maps in SOA Suite and shows the similarities to the WLI XML MetaData Cache Control. Lots of customers have asked about this comparison and I hope they will find it useful. The article follows "Setting Web Service and JCA Adapter Endpoints Dynamically in Oracle SOA Suite" which describes how web services and JCA adapter endpoints in SOA Suite can be changed at run-time, and so completes the use case where a BPEL process writes to a file (via file adapter) and the output directory and the file name are set dynamically. Please let me know what you think about the series and this specific article.

  • WP7 “Phantom Data” Source Possibly Revealed?

    - by Bil Simser
    Recently there’s been rumours floating around regarding “phantom” Windows Phone 7 data being magically sent and received on the latest WP7 phones. The news has mostly been floating around twitter so I didn’t pay it much attention. The BBC Technology News picked it up so I thought I would look more into it myself seeing that we have WP7 phones and maybe there was some truth to all this (and more importantly what was the cause). Full disclosure. I don’t have a lot of data points around this. This is from looking at a few phone logs, changing the configuration and looking back again after the change. I haven’t done a clean baseline test nor have I done testing with hundreds of phones. I leave the experience up to the reader to decide. So I went spelunking into the phone logs to see what was up. Most providers will show you data usage, at least on a daily basis. I lucked out with the provider and plan in that they provide hourly breakdowns. Here’s a snapshot from my usage throughout one night. Timestamp Data Usage 12:38:30 AM 2098 Kilobytes 1:30:30 AM 2 Kilobytes 2:38:30 AM 7118 Kilobytes 3:38:30 AM 6622 Kilobytes 4:38:30 AM 76 Kilobytes 5:38:30 AM 29 Kilobytes 6:38:30 AM 19 Kilobytes 7:38:30 AM 20 Kilobytes So a few observations from this data: Data seems to be collected on a regular basis. Looking at some other people phone logs, the times vary but it’s always hourly. There’s not a tremendous amount of data here (about 16 megabytes) but it seems like a lot for 7 hours The phone was connected to my home Wifi during this period Nothing was running and the phone was in a locked state Like I said, not a lot of data but it adds up. 16MB for 7 hours = about 50MB in a 24 hour period. That’s just plain old data being collected (somewhere, somehow) and not actual usage (Marketplace, Email, Browsing, etc.). Besides, when connected to a WiFi network you shouldn’t be charged data usage from your phone company (in theory, YMMV). After reviewing the logs I made a theory that the only thing that could possibly be sending data is the Feedback feature. With no other apps running under lock, what else could it be? In Windows 7 under your Settings the last option is Feedback. This sends feedback to Microsoft to “help improve Windows Phone”. On this page you have three options: Send feedback and use my cellular data connection Send feedback and (presumably) use my WiFi connection Don’t send feedback Knowing what I know about Microsoft, they do use the feedback data. For example some of the placement and inclusion of features in Office 2007 was based on that Feedback data that Office sends (assuming you had opted in). However in the Privacy Statement (it’s long but a good read at least once in your life), the Phone manual, and every other source I could look at there is no information about how much data it’s planning to send, just that it’s sending some data and that “some data charges with your carrier may apply”. Looking back at the logs, I have to wonder. 6MB at 3:30 and *then* 7MB the next hour. That’s a lot of information. And it adds up. 50MB in a 24 hour period X 30 days puts most people over a normal 1GB plan. And frankly why am I paying for a data plan only to have 80% of it chewed up by Microsoft, with no real benefit to me. If they included porn in the 50mb daily transfer I’d be okay with this, but I don’t see any new movies on my phone. So I turned it off. Set Feedback to disabled and wait. I waited. And waited. And generally didn’t use the phone if I could. The next day I went back to look at the data usage logs from the time period after turning the feedback mechanism off. Here are the results. Timestamp Data Usage 1:19:48 PM 0 Kilobytes 2:19:48 PM 0 Kilobytes 3:19:48 PM 0 Kilobytes 4:19:48 PM 678 Kilobytes (took a phone call) 5:19:48 PM 82 Kilobytes 6:19:48 PM 88 Kilobytes 7:20:30 PM 86 Kilobytes (guess they changed their reporting time) 8:20:30 PM 86 Kilobytes 9:20:30 PM 66 Kilobytes 10:20:30 PM 67 Kilobytes 11:20:30 PM 49 Kilobytes 12:20:30 AM 32 Kilobytes 1:20:30 AM 38 Kilobytes 2:20:31 AM 18 Kilobytes 3:20:31 AM 27 Kilobytes 4:20:31 AM 86 Kilobytes 5:20:31 AM 53 Kilobytes 6:20:31 AM 22 Kilobytes 7:22:15 AM 30 Kilobytes (another reporting time change) 8:22:15 AM 29 Kilobytes 9:22:15 AM 74 Kilobytes 10:22:15 AM 154 Kilobytes (phone call) 11:22:15 AM 12 Kilobytes 12:13:27 PM 49 Kilobytes 1:13:27 PM 197 Kilobytes (phone call) Quite a *drastic* change from what Feedback was turned on. I mean for a 24 hour period (sans 3 phone calls) I consumed about 1MB. Still quite a bit of transfer going on but at least it amounts to 30MB per month, not 30MB per day! Like I said this observation is neither scientific or conclusive. You decide what to do but frankly until Microsoft makes this data transfer exempt from your data plan (like that will happen) I would just turn Feedback off. YMMV.

  • How a .NET Programmer learn Big Data/Hadoop? [on hold]

    - by Smith Pascal Jr.
    I have been ASP.NET developer for sometime now and I have been reading a lot about Big Data- Hadoop and its future as to how it is the next technology in IT and how it would be useful to create million of jobs in US and elsewhere in the world. Now since Hadoop is an open source big data tool which is managed by Apache Server Foundation Group, I'm assuming I have to be well aware of JAVA - Correct me if I'm wrong. Moreover, How a .NET programmer can learn Big Data and its related technologies and can work professionally full time into this technology? What challenges and opportunities does a .NET professional face while changing the technology platform? Please advice. Thanks

  • Is it a good practice to use smaller data types for variables to save memory?

    - by ThePlan
    When I learned the C++ language for the first time I learned that besides int, float etc, smaller or bigger versions of these data types existed within the language. For example I could call a variable x int x; or short int x; The main difference being that short int takes 2 bytes of memory while int takes 4 bytes, and short int has a lesser value, but we could also call this to make it even smaller: int x; short int x; unsigned short int x; which is even more restrictive. My question here is if it's a good practice to use separate data types according to what values your variable take within the program. Is it a good idea to always declare variables according to these data types?
