• The Differences between MAC Address and Network Layer Address

  A Mac address is a fixed number associated with a NICs onboard memory. It is initially assigned at the factory. The MAC address is broken up into 2 parts. The first part is the Block id which is six digit sequences that is unique to each vender. The second section is the device id which is created and assigned by the manufacture. A Network layer address is different because there format based on the type of protocol and network used. Also, there unique id is based on a hierarchal addressing theme on subsets of data  and narrowing it down. Just like in an address you can narrow down your house, for example: Florida, Boca Raton, 33428, SW 53th street states that you live in Florida. You also live in the area located in Florida called Boca Raton and you are also in the area of 33428 which is located in Boca Raton. Finally you live on SW 8th street which is in the area of 33428 which is located in Boca Raton which is also located in Florida.

• Which language is more suitable heavy file tasks?

  - by All

  I need to write a script (based on basic functions) to process /image/audio/video files. The process is mainly filesystem tasks and converts. The database of files has been stored by mysql. The script is simple but cause heavy tasks on the system; for example renaming/converting/copying thousands of file in a run. The script does not read the content of files into memory, it just manage the commands for sub-processes. The main weight is on the communication with filesystem. The script will be used regularly for new files. My concern is about performance. I am thinking of Shell script a complied language like C Please advise which programming language is more suitable for this purpose and why? UPDATE: An example is to scan a folder for images, convert them with ImageMagick, move files to destination folder, get file info, then update the database. As you can see, the process has no room for optimization, and most of languages have similar APIs for popular programs like ImageMagick, MySQL, etc. Thus, it can be written in any language. I just wish to reduce resource usage by speeding up the long loop. NOTE: I know that questions about comparing languages are not favorable, but I really had problem to choose, because the problems can appear in action.

• please help me understand libraries/includes

  - by fiftyeight

  I'm trying to understand how libraries work. for example I downloaded a tarball and extracted it. Now I do "./configure", it searches in pre-defined directories from what I understand for certain library files. What does it do then? it creates a makefile, and the makefile contains the paths to these libraries? than I do "make", it complies the source code and hard-codes the locations of the libraries? am I correct? I do not really understand if libraries are files with pre-defined paths or the OS somehow gives access to the libraries through system calls. another example, I complied something on my computer than moved it to a remote server, the executable needs mysql libraries to work, the server has mysql but for some reason when execute the file it tells me "can't find libmysqlclient.so.16". is there a solution for this? is there a way to know where is tries to locate this file or give it another path? I can't compile it on the server since it has no compiler and I don't have root access to install packages last question is if in the sequence "./configure","make","make install" the "make install" command is the only one that actually puts files outside the directory in which these files reside? if for example the software will be installed in /usr/local/ is the "make install" command the only one that will require "sudo" before it? let me see if I got it correctly: "./configure" creates the Makefile according to the location of various files on your system. "make" compiles the source code according to this makefile. and "make install" moves the files to their appropriate location. I know this has been very long I thank anyone who had the patience to read my question :)

• Does purposely linking to an invalid URL and then using 301 affect SEO?

  - by Mike

  On a section of my site, I am currently using .htaccess rewrites to put the ID as part of the URL instead of in the query, like so: RewriteRule ^([a-z_]+)?/?tours/([0-9]+)/(.*) /tours/tour_text.php?lang=$1&id=$2&urlstr=$3 [L] For example, if someone goes to /en/tours/12/some-text-here it will rewrite it to /tours/tour_text.php?lang=en&id=12&urlstr=some-text-here. However I don't want the users to be able to put just any text, so if they type in the wrong some-text-here part it will 301 redirect them to the right page. This works perfectly, but I can see a potential problem potential arising when localizing the website, so I just wanted to make sure it's not actually a problem. How it is now, if someone goes to /en/tours/12/some-text-here, the anchor to the Spanish version of that page will be /es/tours/12/some-text-here (i.e. only changing the "en" to "es"), and then the script will then 301 them to the correct Spanish text (something like /es/tours/12/algun-texto-aqui). And the reverse will also be the same. The anchor on the Spanish version to the English version would be /en/tours/12/algun-texto-aqui and then they will be forwarded with 301 back to /en/tours/12/some-text-here. Basically, the anchor changes the language and the 301 changes the string at the end. So I have two questions: Does purposely and permanently having invalid URLs on your site that get 301'ed to the correct ones have any effect on SEO? I could make it just show the correct URL to begin with, but this is a significant amount of work due to how I am handling the translations, so I would prefer just to 301 them. Will the invalid URLs that are contained in the links be added to the search engine indexes even if they get 301'ed to another page?

• How to verify that all files are intact prior to install?

  - by Kalle H. Väravas

  I'm working on my CMS (in PHP platform) for a long time now. The main program is done and I'm currently developing the Installer part. Installation itself will be fairly simple: Upload all files Verify that the "content/" dir has correct permissions Check if ALL files are intact and not modified [This is the subject of this question] Insert the config data and first settings Run install (Generate all DB tables and insert sample data etc.) Now the question-mark is at step 3. How do I verify ALL files? Verification itself should compare all CMS root-directories files against a list from remote location. List should contain filename, filesize and filetype. This way the user can check, that there are no unnecessary or corrupted files, that could indicated a breach in the software. I have seen some software installers do that, but I cannot find any right now and there for I'm clueless on the most optimal method for this. Of course there always is a simple array trick, but there surely must be a better and faster method?!

• Amazon AMIs and Oracle VM templates

  - by llaszews

  I have worked with Oracle VM templates and most recently with Amazon Machine Images (AMI). The similarities in the functionality and capabilities they provide are striking. Just take a look a the definitions: An Amazon Machine Image (AMI) is a special type of pre-configured operating system and virtual application software which is used to create a virtual machine within the Amazon Elastic Compute Cloud (EC2). It serves as the basic unit of deployment for services delivered using EC2. AWS AMIs Oracle VM Templates provide an innovative approach to deploying a fully configured software stack by offering pre-installed and pre-configured software images. Use of Oracle VM Templates eliminates the installation and configuration costs, and reduces the ongoing maintenance costs helping organizations achieve faster time to market and lower cost of operations. Oracle VM Templates Other things they have in common: 1. Both have 35 Oracle images or templates: AWS AMI pre-built images Oracle pre-built VM Templates 2. Both allow to build your own images or templates: A. OVM template builder - OVM Template Builder - Oracle VM Template Builder, an open source, graphical utility that makes it easy to use Oracle Enterprise Linux “Just enough OS” (JeOS)–based scripts for developing pre-packaged virtual machines for Oracle VM. B. AMI 'builder' - AMI builder However, AWS has the added feature/benefit of adding your own AMI to the AWS AMI catalog: AMI - Adding to the AWS AMI catalog Another plus with AWS and AMI is there are hundreds of MySQL AMIs (AWS MySQL AMIs ). A benefit of Oracle VM templates is they can run on any public or private cloud environment, not just AWS EC2. However, with Oracle VM templates they first need to be images as AMIs before they can run in the AWS cloud.

• Are XML Comments Necessary Documentation?

  - by Bob Horn

  I used to be a fan of requiring XML comments for documentation. I've since changed my mind for two main reasons: Like good code, methods should be self-explanatory. In practice, most XML comments are useless noise that provide no additional value. Many times we simply use GhostDoc to generate generic comments, and this is what I mean by useless noise: /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } To me, that's obvious. Having said that, if there were special instructions to include, then we should absolutely use XML comments. I like this excerpt from this article: Sometimes, you will need to write comments. But, it should be the exception not the rule. Comments should only be used when they are expressing something that cannot be expressed in code. If you want to write elegant code, strive to eliminate comments and instead write self-documenting code. Am I wrong to think we should only be using XML comments when the code isn't enough to explain itself on its own? I believe this is a good example where XML comments make pretty code look ugly. It takes a class like this... public class RawMaterialLabel : EntityBase { public long Id { get; set; } public string ManufacturerId { get; set; } public string PartNumber { get; set; } public string Quantity { get; set; } public string UnitOfMeasure { get; set; } public string LotNumber { get; set; } public string SublotNumber { get; set; } public int LabelSerialNumber { get; set; } public string PurchaseOrderNumber { get; set; } public string PurchaseOrderLineNumber { get; set; } public DateTime ManufacturingDate { get; set; } public string LastModifiedUser { get; set; } public DateTime LastModifiedTime { get; set; } public Binary VersionNumber { get; set; } public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } } ... And turns it into this: /// <summary> /// Container for properties of a raw material label /// </summary> public class RawMaterialLabel : EntityBase { /// <summary> /// Gets or sets the id. /// </summary> /// <value> /// The id. /// </value> public long Id { get; set; } /// <summary> /// Gets or sets the manufacturer id. /// </summary> /// <value> /// The manufacturer id. /// </value> public string ManufacturerId { get; set; } /// <summary> /// Gets or sets the part number. /// </summary> /// <value> /// The part number. /// </value> public string PartNumber { get; set; } /// <summary> /// Gets or sets the quantity. /// </summary> /// <value> /// The quantity. /// </value> public string Quantity { get; set; } /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } /// <summary> /// Gets or sets the lot number. /// </summary> /// <value> /// The lot number. /// </value> public string LotNumber { get; set; } /// <summary> /// Gets or sets the sublot number. /// </summary> /// <value> /// The sublot number. /// </value> public string SublotNumber { get; set; } /// <summary> /// Gets or sets the label serial number. /// </summary> /// <value> /// The label serial number. /// </value> public int LabelSerialNumber { get; set; } /// <summary> /// Gets or sets the purchase order number. /// </summary> /// <value> /// The purchase order number. /// </value> public string PurchaseOrderNumber { get; set; } /// <summary> /// Gets or sets the purchase order line number. /// </summary> /// <value> /// The purchase order line number. /// </value> public string PurchaseOrderLineNumber { get; set; } /// <summary> /// Gets or sets the manufacturing date. /// </summary> /// <value> /// The manufacturing date. /// </value> public DateTime ManufacturingDate { get; set; } /// <summary> /// Gets or sets the last modified user. /// </summary> /// <value> /// The last modified user. /// </value> public string LastModifiedUser { get; set; } /// <summary> /// Gets or sets the last modified time. /// </summary> /// <value> /// The last modified time. /// </value> public DateTime LastModifiedTime { get; set; } /// <summary> /// Gets or sets the version number. /// </summary> /// <value> /// The version number. /// </value> public Binary VersionNumber { get; set; } /// <summary> /// Gets the lot equipment scans. /// </summary> /// <value> /// The lot equipment scans. /// </value> public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } }

• Graph data structures and journal format for mini-IDE

  - by matec

  Background: I am writing a small/partial IDE. Code is internally converted/parsed into a graph data structure (for fast navigation, syntax-check etc). Functionality to undo/redo (also between sessions) and restoring from crash is implemented by writing to and reading from journal. The journal records modifications to the graph (not to the source). Question: I am hoping for advice on a decision on data-structures and journal format. For the graph I see two possible versions: g-a Graph edges are implemented in the way that one node stores references to other nodes via memory address g-b Every node has an ID. There is an ID-to-memory-address map. Graph uses IDs (instead of addresses) to connect nodes. Moving along an edge from one node to another each time requires lookup in ID-to-address map. And also for the journal: j-a There is a current node (like current working directory in a shell + file-system setting). The journal contains entries like "create new node and connect to current", "connect first child of current node" (relative IDs) j-b Journal uses absolute IDs, e.g. "delete edge 7 - 5", "delete node 5" I could e.g. combine g-a with j-a or combine g-b with j-b. In principle also g-b and j-a should be possible. [My first/original attempt was g-a and a version of j-b that uses addresses, but that turned out to cause severe restrictions: nodes cannot change their addresses (or journal would have to keep track of it), and using journal between two sessions is a mess (or even impossible)] I wonder if variant a or variant b or a combination would be a good idea, what advantages and disadvantages they would have and especially if some variant might be causing troubles later.

• Generalise variable usage inside code

  - by Shirish11

  I would like to know if it is a good practice to generalize variables (use single variable to store all the values). Consider simple example Strings querycre,queryins,queryup,querydel; querycre = 'Create table XYZ ...'; execute querycre ; queryins = 'Insert into XYZ ...'; execute queryins ; queryup = 'Update XYZ set ...'; execute queryup; querydel = 'Delete from XYZ ...'; execute querydel ; and Strings query; query= 'Create table XYZ ... '; execute query ; query= 'Insert into XYZ ...'; execute query ; query= 'Update XYZ set ...'; execute query ; query= 'Delete from XYZ ...'; execute query ; In first case I use 4 strings each storing data to perform the actions mentioned in their suffixes. In second case just 1 variable to store all kinds the data. Having different variables makes it easier for someone else to read and understand it better. But having too many of them makes it difficult to manage. Also does having too many variables hamper my performance?

• flat files vs. RDBMS database, few read/writes, few changes

  - by Bob Lapique

  I have to handle data from long term (years, decades) climate monitoring stations. The data flow usually starts with raw data (voltages, etc.) plus quality check information (pressure, temperature, flow rate, etc.) generally recorded @ 1Hz. Then, the data are assigned a quality flag (human and/or program), processed (apply calibration curves) and flagged. So, we basically end up with 2 datasets : raw and processed data. New data are typically added once a day (~500Ko/day/instrument). Simultaneous queries are not likely to ever happen. I wanted to go for a RDBMS (we have a MySQL server) and have some experience in database design, but the IT guy keeps telling me that flat files will to the job just as well. I suspect him to try to make his life easier when it comes to backup/upgrade the MySQL. There are not so many links between data, they don't change much, but the quality flags will change. A RDBMS is easier to compare data from different instruments on a "many days" scale, compared to daily text files. Well, what would you advise ? Thanks.

• Need help to make a decision in career switch over? [closed]

  - by Fero

  I am a Software Engineer having 4 Years of experinece in web development using PHP, Drupal, MySql, Ajax and client site technologies like javascript, jquery,html and more. I have decided two platforms to switch over my career. SAP-ABAP (Because ABAP is related to coding) SALES FORCE One and only reason is that I am not getting good pack for the technologies what I am working with. Even top level companies are not ready to pay for this technologies. (And I am not expecting more.) To be honest I am good at technical and HR interviews too. So, I started to make an analysis of highly payable platforms and I got these two. SAP and Salesforce (Probabilty of On-site opportunity is also very high on both) Here my questions are: I am totally new to the above mentioned technologies. Which will be best suit for me ? Having basic ideas of the platforms what I have decided - But I am confused to choose I am having Good Coding experiencein PHP, Drupal as well as good experience in MySql. Having very good experience in creating sites related to E-Commerce, LMS, Q&A sites, Travel Sites, Blogs, Social networking site and more. Which I can learn easily or for which I can get good documentations online Kindly understand that I am not creating a debate over here. I hope Professionals over here can Show me the correct path.... I am waiting to travel on that...

• OpenOffice Calc: How can I count the number of different items with data pilot?

  - by manu

  Hi all, I have a rather long spreadsheet with historical information of issues solved by some user on a colaborative environment. The spreadsheet have the following (relevant) columns date, week no., project, author id, etc... The week no. is calculated from the date, is basically the year concatenated with the week number within that year; for instance, both 2009-02-18 and 2009-02-20 yield the week number 200908 - the 8th week of year 2009; and 2009-02-23 yields 200909 - the 9th week of year 2009. I need to count how many different users (given by author id) contributed to some project, on a weekly basis. I have setup a data pilot with the week as Row Field, the project as the Column Field, and count-author as the Data Field. However, this counts the author id as different instances. This is not what I need. I need to count how many different users contributed to each project on a weekly basis. I expect to get something like: projects week Project1 Project2 Project3 200901 10 2 200902 2 7 Each inner cell containing how many different users contributed. With the count-author configuration, what I get is how many contributions (total) got the project on that week. Is there a way to tell OpenOffice Calc to do what I want?

• Pasting from vim in terminal to Google Docs (Firefox + Vimperator) - need to understand

  - by LIttle Ancient Forest Kami

  I had some trouble with copy-pasting text from vim in terminal to Google Docs (aka Drive) document (hereafter GDd) in FF browser (with Vimperator). Note: I have a file opened in Vim 7.2 in terminal :version displays both +clipboard and +xterm-clipboard I'm on Ubuntu 10.04 LTS, so I don't think that's Unity-related I want to use Vim, not GVim, nor gedit... I'm avid fan of mouseless navigation, so solution with mouse was not what I wanted. I have the solution, but I need understanding. What I tried and where it gets me: Yanking whole file text via: ggvGy allows me to: paste it via mouse middle button, NOT with Ctrl+v or Shift+Insert here, in text area for entering question text in gedit but NOT in GDd where I want it pasted, even if I switch Vimperator to pass-through mode with Insert does NOT show in XClip after xclip -o From gedit, I can copy-paste the text into GDd (Vimperator's pass-through mode not required). :%! !xclip -i (or :first, last) reports whole file (all lines, to be precise) as filtered, though shell returns 1 `xclip -o' returns nothing (is empty) or returns previously copied value with 2. no surprise, but I can't paste at all not only to GDd but also to gedit or here setting clipboard (:set clipboard=unnamed) to unnamed doesn't help using "+y or "*y on whole file text actually does the trick So, the question (it's actually three, say "split" and I will): why middle mouse button pastes different things than Ctrl+v and how to know what will be pasted with each? why just yanking (without registers) works with mouse but not with keyboard / XClip? why didn't unnamed register help? After setting, it should make unnamed and * registers same?

• Create MSDB Folders Through Code

  You can create package folders through SSMS, but you may also wish to do this as part of a deployment process or installation. In this case you will want programmatic method for managing folders, so how can this be done? The short answer is, go and look at the table msdb.dbo. sysdtspackagefolders90. This where folder information is stored, using a simple parent and child hierarchy format. To add new folder directly we just insert into the table - INSERT INTO dbo.sysdtspackagefolders90 ( folderid ,parentfolderid ,foldername) VALUES ( NEWID() -- New GUID for our new folder ,<<Parent Folder GUID>> -- Lookup the parent folder GUID if a child or another folder, or use the root GUID 00000000-0000-0000-0000-000000000000 ,<<Folder Name>>) -- New folder name There are also some stored procedures - sp_dts_addfolder sp_dts_deletefolder sp_dts_getfolder sp_dts_listfolders sp_dts_renamefolder To add a new folder to the root we could call the sp_dts_addfolder to stored procedure - EXEC msdb.dbo.sp_dts_addfolder @parentfolderid = '00000000-0000-0000-0000-000000000000' -- Root GUID ,@name = 'New Folder Name The stored procedures wrap very simple SQL statements, but provide a level of security, as they check the role membership of the user, and do not require permissions to perform direct table modifications.

• Am I missing something about these considerations about Leaderboard's database's schema?

  - by misiMe

  I just finished to develop a mobile game, now I want to implement an online leaerboard using mysql. I'm wondering about the database's schema, I thought about some possibilities: (I didn't got in detail with syntax because my question is just about the logic of it) Name: string; Score: integer I thought to ask the name just the first time. If, in the future, you will modify that, it will call just an update to the name associated with your id. Leaderboard(ID, Name, Score) ID: integer autoincrement, PrimaryKey With this kind of idea maybe the db will grow fast because if you choose everytime a different name for the score, it will add a new entry. Leaderboard(PhoneId, Name, Score) Here PhoneId will be the unique identifier of the phone, PrimaryKey. A con of this choice is that if you want to play with your friends' phone, you can't put a different name for the score. Leaderboard(Name, Score) Here Name is PrimaryKey. With that, if you enter a name that already exists, you will be prompted to choose another one. Do you agree with this considerations? What will you do? Am I missing something?

• Using runtime generic type reflection to build a smarter DAO

  - by kerry

  Have you ever wished you could get the runtime type of your generic class? I wonder why they didn’t put this in the language. It is possible, however, with reflection: Consider a data access object (DAO) (note: I had to use brackets b/c the arrows were messing with wordpress): public interface Identifiable { public Long getId(); } public interface Dao { public T findById(Long id); public void save(T obj); public void delete(T obj); } Using reflection, we can create a DAO implementation base class, HibernateDao, that will work for any object: import java.lang.reflect.Field; import java.lang.reflect.ParameterizedType; public class HibernateDao implements Dao { private final Class clazz; public HibernateDao(Session session) { // the magic ParameterizedType parameterizedType = (ParameterizedType) clazz.getGenericSuperclass(); return (Class) parameterizedType.getActualTypeArguments()[0]; } public T findById(Long id) { return session.get(clazz, id); } public void save(T obj) { session.saveOrUpdate(obj); } public void delete(T obj) { session.delete(obj); } } Then, all we have to do is extend from the class: public class BookDaoHibernateImpl extends HibernateDao { }

• MongoDB: Replicate data in documents vs. “join”

  - by JavierCane

  Disclaimer: This is a question derived from this one. What do you think about the following example of use case? I have a table containing orders. These orders has a lot of related information needed by my current queries (think about the products; the buyer information; the region, country and state of the sale point; and so on) In order to think with a de-normalized approach, I don't have to put identifiers of these related items in my main orders collection. Instead, I have to repeat all the information for each order (ie: I will repeat the buyer's name, surname, etc. for each of its orders). Assuming the previous premise, I'm committing to maintain all the data related to an order without a lot of updates (because if I modify the buyer's name, I'll have to iterate through all orders updating the ones made by the same buyer, and as MongoDB blocks at a document level on updates, I would be blocking the entire order at the update moment). I'll have to replicate all the products' related data? (ie: category, maker and optional attributes like color, size…) What if a new feature is requested and I've to make a lot of queries with the products "as the entry point of the query"? (ie: reports showing the products' sales performance grouping by region, country, or whatever) Is it fair enough to apply the $unwind operation to my orders original collection? (What about the performance?) I should have to do another collection with these queries in mind and replicate again all the products' information (and their orders)? Wouldn't be better to store a product_id in the original orders collection in order to be more tolerable to requirements change? (What about emulating JOINs?) The optimal approach would be a mixed solution with a RDBMS system like MySQL in order to retrieve the complete data? I mean: store products, users, and location identifiers in the orders collection and have queries in MySQL like getAllUsersDataByIds in which I would perform a SELECT * FROM users WHERE user_id IN ( :identifiers_retrieved_from_the_mongodb_query )

• Cannot view, use, or open CDs or DVDs in Ubuntu 12.04

  - by user67592

  I am fairly new to Ubuntu 12.04 and I have encountered a rather irritating problem. Whenever I insert a CD or DVD (whether it have data, music, movies, or nothing at all), nothing pops up saying "you have inserted a CD", "play with Rhythmbox?" etc. It doesn't show the CD in the launcher/dock or anything of the sort. This is especially peculiar because not only do I have a standard IDE built-in optical drive, but I have an external USB optical drive. Neither work. In addition, whenever I go to "Computer///" and I click (double click, right click, or even left click) on "CD/DVD Drive" nothing happens, when I right click and select "Open" nothing happens either [for either of the two drives (both are listed in Computer///)] And if I insert a blank disk and go to a disk burning program such as Brasero, and try to burn to the drive it detects no CDs or DVDs of any kind. I'm rather stumped and can't seem to find a question similar to this. :( Thanks for all your help in advance!! :) ~Preston Output of sudo lshw *-cdrom description: DVD-RAM writer product: CD/DVDW TS-H652M vendor: TSSTcorp physical id: 0.0.0 bus info: scsi@5:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0414 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc *-cdrom description: DVD reader product: DVD Writer 300n vendor: HP physical id: 0.0.0 bus info: scsi@4:0.0.0 logical name: /dev/cdrom2 logical name: /dev/cdrw2 logical name: /dev/dvd2 logical name: /dev/sr1 version: 1.25 serial: [ capabilities: removable audio cd-r cd-rw dvd configuration: status=nodisc
