  • can connect to wifi router but not the internet 12.10

    - by harsh
    I believe i have tried every trick in the book ! I am able to access my router from my ubuntu desktop but not even a single site on the internet. i have installed the drivers for my pci wifi card following this procedure : http://steveswinsburg.wordpress.com/2011/03/12/how-to-install-a-d-link-dwa-525-wireless-network-card-in-ubuntu-10-04/ Earlier it didn't connect to the internet and kept prompting me for the password. after i installed the driver it got connected ! but now i cant access the internet and can only access my router. i deleted the resolv.conf file. I have also tried the "rkill" command and it shows it is unlocked. I have even tried pinging the ip's 8.8.8.8 & 8.8.4.4 and i get replies from both. I have also added them on my wifi configuration setup on ubuntu desktop. I am new to ubuntu but learning fast :-) These are the things i don't like about ubuntu, the simple tasks are difficult for a person coming from windows. I am using ubuntu 12.10. please reply at the earliest i would be very thankful.

  • Bulk Rename Tool is a Lightweight but Powerful File Renaming Tool

    - by Jason Fitzpatrick
    There’s no need to settle for overly simplistic file renaming tools as long as Bulk Rename Tool is around. It’s lightweight, insanely customizable, portable, and sure to make short work of any renaming task you throw at it. Bulk Rename Tool is a great portable application (available as an installed version if you crave context menu integration) that blasts through file renaming tasks. The main panel is intimidatingly packed with toggles and variables you can alter; this isn’t a one-click solution by any means. That said, once you get comfortable using the interface it’s lightening fast and extremely flexible. One tip that will save you an enormous amount of frustrating when you get started: make sure to highlight the files you want to change in the file preview window (located in the upper right corner) or else you won’t see the preview and won’t know if the changes you’re making in the control panel are yielding the file names you desire. Hit up the link below to read more and grab a copy; Bulk Rename Tool is free, Windows only.

  • Why do I need to create a bios-grub partition when I install 12.04?

    - by raj
    Is the bios-grub partition in Ubuntu 12.04 mandatory? I have used 11.04, 11.10 and 12.04, But I was never asked for this. Today I tried a fresh installation of Ubuntu 12.04 and for the first time I was asked for this Grub partition of minimum 1Mb. I first tried to reinstall 12.04, but the error continued. So I installed Fedora 16, Keeping all partitions as they were (replaced Ubuntu with Fedora), And then did another fresh installation of 12.04. Is it ok to continue with this grub partition or is there a fault in my system's hardware? If this is a (hardware) fault, how can I fix it? I'm using a Lenovo S10-2 Ideapad. The only OS right now installed is Ubuntu 12.04. well, let me answer. It was /usr/bin/xorg issue that I had with firstly installed precise. I used fedora16 basically for removing precise totally (my experience tells me ubuntu can't completely erase and reinstall by itself). this 1mb grub is created by fedora. I then wanted to remove it while reinstalling ubuntu but got caution bootloader may fail. hence I have to keep this 1mb drive. but prior to yesterday, i used both fedora and ubuntu, even same CDs, but had no such partition. my question is if this partition is necessary or not? if not, how can i safely remove it from my system? Am using only ubuntu 12.04 -- before and after (now).

  • How do I install Red5 using apt-get? Getting sub-process error

    - by Dalen
    This is copy from question of some guy on other forum that never got satisfiably answered. I encountered the same error few days ago on Ubuntu 13.04 Desktop. It seems like Red5 is installed but it cannot be run for some reason. Can anyone explain what is going on here? Why should dpkg fail? I mean, this is checked repo, it should work fine. apt-get install red5-server Selecting previously deselected package red5-server. (Reading database ... 53491 files and directories currently installed.) Unpacking red5-server (from .../red5-server_0.9.1-4squeeze1_all.deb) ... Setting up red5-server (0.9.1-4squeeze1) ...

  • unit/integration testing web service proxy client

    - by cori
    I'm rewriting a PHP client/proxy library that provides an interface to a SOAP-based .Net webservice, and in the process I want to add some unit and integration tests so future modifications are less risky. The work the library I'm working on performs is to marshall the calls to the web service and do a little reorganizing of the responses to present a slightly more -object-oriented interface to the underlying service. Since this library is little else than a thin layer on top of web service calls, my basic assumption is that I'll really be writing integration tests more than unit tests - for example, I don't see any reason to mock away the web service - the work that's performed by the code I'm working on is very light; it's almost passing the response from the service right back to its consumer. Most of the calls are basic CRUD operations: CreateRole(), CreateUser(), DeleteUser(), FindUser(), &ct. I'll be starting from a known database state - the system I'm using for these tests is isolated for testing purposes, so the results will be more or less predictable. My question is this: is it natural to use web service calls to confirm the results of operations within the tests and to reset the state of the application within the scope of each test? Here's an example: One test might be createUserReturnsValidUserId() and might go like this: public function createUserReturnsValidUserId() { // we're assuming a global connection to the service $newUserId = $client->CreateUser("user1"); assertNotNull($newUserId); assertNotNull($client->FindUser($newUserId); $client->deleteUser($newUserId); } So I'm creating a user, making sure I get an ID back and that it represents a user in the system, and then cleaning up after myself (so that later tests don't rely on the success or failure of this test w/r/t the number of users in the system, for example). However this still seems pretty fragile - lots of dependencies and opportunities for tests to fail and effect the results of later tests, which I definitely want to avoid. Am I missing some options of ways to decouple these tests from the system under test, or is this really the best I can do? I think this is a fairly general unit/integration testing question, but if it matters I'm using PHPUnit for the testing framework.

  • Why am I not getting an sRGB default framebuffer?

    - by Aaron Rotenberg
    I'm trying to make my OpenGL Haskell program gamma correct by making appropriate use of sRGB framebuffers and textures, but I'm running into issues making the default framebuffer sRGB. Consider the following Haskell program, compiled for 32-bit Windows using GHC and linked against 32-bit freeglut: import Foreign.Marshal.Alloc(alloca) import Foreign.Ptr(Ptr) import Foreign.Storable(Storable, peek) import Graphics.Rendering.OpenGL.Raw import qualified Graphics.UI.GLUT as GLUT import Graphics.UI.GLUT(($=)) main :: IO () main = do (_progName, _args) <- GLUT.getArgsAndInitialize GLUT.initialDisplayMode $= [GLUT.SRGBMode] _window <- GLUT.createWindow "sRGB Test" -- To prove that I actually have freeglut working correctly. -- This will fail at runtime under classic GLUT. GLUT.closeCallback $= Just (return ()) glEnable gl_FRAMEBUFFER_SRGB colorEncoding <- allocaOut $ glGetFramebufferAttachmentParameteriv gl_FRAMEBUFFER gl_FRONT_LEFT gl_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING print colorEncoding allocaOut :: Storable a => (Ptr a -> IO b) -> IO a allocaOut f = alloca $ \ptr -> do f ptr peek ptr On my desktop (Windows 8 64-bit with a GeForce GTX 760 graphics card) this program outputs 9729, a.k.a. gl_LINEAR, indicating that the default framebuffer is using linear color space, even though I explicitly requested an sRGB window. This is reflected in the rendering results of the actual program I'm trying to write - everything looks washed out because my linear color values aren't being converted to sRGB before being written to the framebuffer. On the other hand, on my laptop (Windows 7 64-bit with an Intel graphics chip), the program prints 0 (huh?) and I get an sRGB default framebuffer by default whether I request one or not! And on both machines, if I manually create a non-default framebuffer bound to an sRGB texture, the program correctly prints 35904, a.k.a. gl_SRGB. Why am I getting different results on different hardware? Am I doing something wrong? How can I get an sRGB framebuffer consistently on all hardware and target OSes?

  • Dlink DWA-643 ExpressCard / Atheros AR5008 can't connect to wifi networks

    - by Justin Kelly
    I've just purchased a D-Link DWA-643 Xtreme N ExpressCard Notebook Adapter - but it can't connect to my wireless network The card is listed on the FSF website and - refer links below: http://www.fsf.org/resources/hw/index_html/net/wireless/index_html/cards.html http://www.dlink.com.au/products/?pid=550 Ubuntu see the card as using the Atheros AR5008 chipset - refer image below The card lights up and I can see that available wifi networks using this card - so it seems to 'just work' on ubuntu 12.04 but when i try and connect to my networks - it fails I've tried setting the network to all the different options (WEP, WPA2, no encryption, etc.. b/g/n ) but ubuntu sill cant connect to it I've also installed wicd but still couldn't connect Has anyone got a DWA-643 to work in Ubuntu? Or does anyone have any suggestion on how to get it to connect?? Any help would be greatly appreciated Note: the laptop has built in wifi but its broadcom, works but with dialup speed connection - and i've had nothign but trouble using the boardcom drivers so purchased the FSF recommended PCI expresscard as i hoped it would 'just work' on the latest Ubuntu i've have tried to disable the built in wifi - broadcom - but even with the broadcom uninstall and unavailable it didnt help the dlink to connect previously I had MAC address filtering on the router - i've added the dlinks MAC - and also disabled MAC address filtering - still no luck lspci output below: 18:00.0 Network controller: Atheros Communications Inc.

  • Problems compiling with Quickly

    - by espectalll123
    Welcome to another of my questions about compiling! :P So, after days of stress trying to compile my app, first manually, after porting the project to Quickly, I decided to create the project from scratch using this time Quickly. Now I've finished the app, it works great using quickly run and I haven't added any new file, just removed, replaced or modified. But it can't be compiled using quickly package --verbose --extras... why, if there doesn't seems to be errors related with my project? The fail happens because python-mkdebian doesn't haves enough parameters to work. The terminal output (in Spanish): running install_egg_info Writing /tmp/tmpsT6Pms/virtuam-0.1.egg-info WARNING: the following files are not recognized by DistUtilsExtra.auto: help/C/figures/icon.png help/C/index.page help/C/preferences.page help/C/topic1.page virtuam.desktop.in Traceback (most recent call last): File "/usr/bin/python-mkdebian", line 368, in <module> egg = get_egg_info() File "/usr/bin/python-mkdebian", line 35, in get_egg_info k, v = l.strip().split(': ', 1) ValueError: need more than 1 value to unpack Ha ocurrido un error al crear el paquete Debian ERROR: no se puede crear o actualizar paquete ubuntu Error: la orden package ha fallado Cancelando

  • Developing Schema Compare for Oracle (Part 2): Dependencies

    - by Simon Cooper
    In developing Schema Compare for Oracle, one of the issues we came across was the size of the databases. As detailed in my last blog post, we had to allow schema pre-filtering due to the number of objects in a standard Oracle database. Unfortunately, this leads to some quite tricky situations regarding object dependencies. This post explains how we deal with these dependencies. 1. Cross-schema dependencies Say, in the following database, you're populating SchemaA, and synchronizing SchemaA.Table1: SOURCE   TARGET CREATE TABLE SchemaA.Table1 ( Col1 NUMBER REFERENCES SchemaB.Table1(Col1));   CREATE TABLE SchemaA.Table1 ( Col1 VARCHAR2(100) REFERENCES SchemaB.Table1(Col1)); CREATE TABLE SchemaB.Table1 ( Col1 NUMBER PRIMARY KEY);   CREATE TABLE SchemaB.Table1 ( Col1 VARCHAR2(100) PRIMARY KEY); We need to do a rebuild of SchemaA.Table1 to change Col1 from a VARCHAR2(100) to a NUMBER. This consists of: Creating a table with the new schema Inserting data from the old table to the new table, with appropriate conversion functions (in this case, TO_NUMBER) Dropping the old table Rename new table to same name as old table Unfortunately, in this situation, the rebuild will fail at step 1, as we're trying to create a NUMBER column with a foreign key reference to a VARCHAR2(100) column. As we're only populating SchemaA, the naive implementation of the object population prefiltering (sticking a WHERE owner = 'SCHEMAA' on all the data dictionary queries) will generate an incorrect sync script. What we actually have to do is: Drop foreign key constraint on SchemaA.Table1 Rebuild SchemaB.Table1 Rebuild SchemaA.Table1, adding the foreign key constraint to the new table This means that in order to generate a correct synchronization script for SchemaA.Table1 we have to know what SchemaB.Table1 is, and that it also needs to be rebuilt to successfully rebuild SchemaA.Table1. SchemaB isn't the schema that the user wants to synchronize, but we still have to load the table and column information for SchemaB.Table1 the same way as any table in SchemaA. Fortunately, Oracle provides (mostly) complete dependency information in the dictionary views. Before we actually read the information on all the tables and columns in the database, we can get dependency information on all the objects that are either pointed at by objects in the schemas we’re populating, or point to objects in the schemas we’re populating (think about what would happen if SchemaB was being explicitly populated instead), with a suitable query on all_constraints (for foreign key relationships) and all_dependencies (for most other types of dependencies eg a function using another function). The extra objects found can then be included in the actual object population, and the sync wizard then has enough information to figure out the right thing to do when we get to actually synchronize the objects. Unfortunately, this isn’t enough. 2. Dependency chains The solution above will only get the immediate dependencies of objects in populated schemas. What if there’s a chain of dependencies? A.tbl1 -> B.tbl1 -> C.tbl1 -> D.tbl1 If we’re only populating SchemaA, the implementation above will only include B.tbl1 in the dependent objects list, whereas we might need to know about C.tbl1 and D.tbl1 as well, in order to ensure a modification on A.tbl1 can succeed. What we actually need is a graph traversal on the dependency graph that all_dependencies represents. Fortunately, we don’t have to read all the database dependency information from the server and run the graph traversal on the client computer, as Oracle provides a method of doing this in SQL – CONNECT BY. So, we can put all the dependencies we want to include together in big bag with UNION ALL, then run a SELECT ... CONNECT BY on it, starting with objects in the schema we’re populating. We should end up with all the objects that might be affected by modifications in the initial schema we’re populating. Good solution? Well, no. For one thing, it’s sloooooow. all_dependencies, on my test databases, has got over 110,000 rows in it, and the entire query, for which Oracle was creating a temporary table to hold the big bag of graph edges, was often taking upwards of two minutes. This is too long, and would only get worse for large databases. But it had some more fundamental problems than just performance. 3. Comparison dependencies Consider the following schema: SOURCE   TARGET CREATE TABLE SchemaA.Table1 ( Col1 NUMBER REFERENCES SchemaB.Table1(col1));   CREATE TABLE SchemaA.Table1 ( Col1 VARCHAR2(100)); CREATE TABLE SchemaB.Table1 ( Col1 NUMBER PRIMARY KEY);   CREATE TABLE SchemaB.Table1 ( Col1 VARCHAR2(100)); What will happen if we used the dependency algorithm above on the source & target database? Well, SchemaA.Table1 has a foreign key reference to SchemaB.Table1, so that will be included in the source database population. On the target, SchemaA.Table1 has no such reference. Therefore SchemaB.Table1 will not be included in the target database population. In the resulting comparison of the two objects models, what you will end up with is: SOURCE  TARGET SchemaA.Table1 -> SchemaA.Table1 SchemaB.Table1 -> (no object exists) When this comparison is synchronized, we will see that SchemaB.Table1 does not exist, so we will try the following sequence of actions: Create SchemaB.Table1 Rebuild SchemaA.Table1, with foreign key to SchemaB.Table1 Oops. Because the dependencies are only followed within a single database, we’ve tried to create an object that already exists. To fix this we can include any objects found as dependencies in the source or target databases in the object population of both databases. SchemaB.Table1 will then be included in the target database population, and we won’t try and create objects that already exist. All good? Well, consider the following schema (again, only explicitly populating SchemaA, and synchronizing SchemaA.Table1): SOURCE   TARGET CREATE TABLE SchemaA.Table1 ( Col1 NUMBER REFERENCES SchemaB.Table1(col1));   CREATE TABLE SchemaA.Table1 ( Col1 VARCHAR2(100)); CREATE TABLE SchemaB.Table1 ( Col1 NUMBER PRIMARY KEY);   CREATE TABLE SchemaB.Table1 ( Col1 VARCHAR2(100) PRIMARY KEY); CREATE TABLE SchemaC.Table1 ( Col1 NUMBER);   CREATE TABLE SchemaC.Table1 ( Col1 VARCHAR2(100) REFERENCES SchemaB.Table1); Although we’re now including SchemaB.Table1 on both sides of the comparison, there’s a third table (SchemaC.Table1) that we don’t know about that will cause the rebuild of SchemaB.Table1 to fail if we try and synchronize SchemaA.Table1. That’s because we’re only running the dependency query on the schemas we’re explicitly populating; to solve this issue, we would have to run the dependency query again, but this time starting the graph traversal from the objects found in the other database. Furthermore, this dependency chain could be arbitrarily extended.This leads us to the following algorithm for finding all the dependencies of a comparison: Find initial dependencies of schemas the user has selected to compare on the source and target Include these objects in both the source and target object populations Run the dependency query on the source, starting with the objects found as dependents on the target, and vice versa Repeat 2 & 3 until no more objects are found For the schema above, this will result in the following sequence of actions: Find initial dependenciesSchemaA.Table1 -> SchemaB.Table1 found on sourceNo objects found on target Include objects in both source and targetSchemaB.Table1 included in source and target Run dependency query, starting with found objectsNo objects to start with on sourceSchemaB.Table1 -> SchemaC.Table1 found on target Include objects in both source and targetSchemaC.Table1 included in source and target Run dependency query on found objectsNo objects found in sourceNo objects to start with in target Stop This will ensure that we include all the necessary objects to make any synchronization work. However, there is still the issue of query performance; the CONNECT BY on the entire database dependency graph is still too slow. After much sitting down and drawing complicated diagrams, we decided to move the graph traversal algorithm from the server onto the client (which turned out to run much faster on the client than on the server); and to ensure we don’t read the entire dependency graph onto the client we also pull the graph across in bits – we start off with dependency edges involving schemas selected for explicit population, and whenever the graph traversal comes across a dependency reference to a schema we don’t yet know about a thunk is hit that pulls in the dependency information for that schema from the database. We continue passing more dependent objects back and forth between the source and target until no more dependency references are found. This gives us the list of all the extra objects to populate in the source and target, and object population can then proceed. 4. Object blacklists and fast dependencies When we tested this solution, we were puzzled in that in some of our databases most of the system schemas (WMSYS, ORDSYS, EXFSYS, XDB, etc) were being pulled in, and this was increasing the database registration and comparison time quite significantly. After debugging, we discovered that the culprits were database tables that used one of the Oracle PL/SQL types (eg the SDO_GEOMETRY spatial type). These were creating a dependency chain from the database tables we were populating to the system schemas, and hence pulling in most of the system objects in that schema. To solve this we introduced blacklists of objects we wouldn’t follow any dependency chain through. As well as the Oracle-supplied PL/SQL types (MDSYS.SDO_GEOMETRY, ORDSYS.SI_COLOR, among others) we also decided to blacklist the entire PUBLIC and SYS schemas, as any references to those would likely lead to a blow up in the dependency graph that would massively increase the database registration time, and could result in the client running out of memory. Even with these improvements, each dependency query was taking upwards of a minute. We discovered from Oracle execution plans that there were some columns, with dependency information we required, that were querying system tables with no indexes on them! To cut a long story short, running the following query: SELECT * FROM all_tab_cols WHERE data_type_owner = ‘XDB’; results in a full table scan of the SYS.COL$ system table! This single clause was responsible for over half the execution time of the dependency query. Hence, the ‘Ignore slow dependencies’ option was born – not querying this and a couple of similar clauses to drastically speed up the dependency query execution time, at the expense of producing incorrect sync scripts in rare edge cases. Needless to say, along with the sync script action ordering, the dependency code in the database registration is one of the most complicated and most rewritten parts of the Schema Compare for Oracle engine. The beta of Schema Compare for Oracle is out now; if you find a bug in it, please do tell us so we can get it fixed!

  • How to restore curropted installation?

    - by nightweels
    I have a laptop with dead battery that when there is no current connected to it turns critical so fast and in the energy management in ubuntu, when the battery is critical, there are 2 options: shutdown and hibernate witch is in grey (unclickable), so I have no choice but to chose immediate shutdown, there is no standby even if it is an option in the screen behavior. An immediate shutdown (and I mean by immediate the one that we use when we ended using the computer) happened while I was installing a program called quickly, so after the power was restored, I tried to reinstall the program then I get this translated message: An untreatable error occurred: It seems there is a software error in aptdaemon, the program that lets you install and remove software and any other task related to package management. details: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 968, in simulate trans.unauthenticated = self._simulate_helper(trans) File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1092, in _simulate_helper return depends, self._cache.required_download, \ File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 235, in required_download pm.get_archives(fetcher, self._list, self._records) SystemError: E:I wasn't able to locate a file for the libpng12-dev package.

  • Gemalto Mobile Payment Platform on Oracle T4

    - by user938730
    Gemalto is the world leader in digital security, at the heart of our rapidly evolving digital society. Billions of people worldwide increasingly want the freedom to communicate, travel, shop, bank, entertain and work – anytime, everywhere – in ways that are convenient, enjoyable and secure. Gemalto delivers on their expanding needs for personal mobile services, payment security, identity protection, authenticated online services, cloud computing access, eHealthcare and eGovernment services, modern transportation solutions, and M2M communication. Gemalto’s solutions for Mobile Financial Services are deployed at over 70 customers worldwide, transforming the way people shop, pay and manage personal finance. In developing markets, Gemalto Mobile Money solutions are helping to remove the barriers to financial access for the unbanked and under-served, by turning any mobile device into a payment and banking instrument. In recent benchmarks by our Oracle ISVe Labs, the Gemalto Mobile Payment Platform demonstrated outstanding performance and scalability using the new T4-based Oracle Sun machines running Solaris 11. Using a clustered environment on a mid-range 2x2.85GHz T4-2 Server (16 cores total, 128GB memory) for the application tier, and an additional dedicated Intel-based (2x3.2GHz Intel-Xeon X4200) Oracle database server, the platform processed more than 1,000 transactions per second, limited only by database capacity --higher performance was easily achievable with a stronger database server. Near linear scalability was observed by increasing the number of application software components in the cluster. These results show an increase of nearly 300% in processing power and capacity on the new T4-based servers relative to the previous generation of Oracle Sun CMT servers, and for a comparable price. In the fast-evolving Mobile Payment market, it is crucial that the underlying technology seamlessly supports Service Providers as the customer-base ramps up, use cases evolve and new services are launched. These benchmark results demonstrate that the Gemalto Mobile Payment Platform is designed to meet the needs of any deployment scale, whether targeting 5 or 100 million subscribers. Oracle Solaris 11 DTrace technology helped to pinpoint performance issues and tune the system accordingly to achieve optimal computation resources utilization.

  • In the days of modern computing, in 'typical business apps' - why does performance matter?

    - by Prog
    This may seem like an odd question to some of you. I'm a hobbyist Java programmer. I have developed several games, an AI program that creates music, another program for painting, and similar stuff. This is to tell you that I have an experience in programming, but not in professional development of business applications. I see a lot of talk on this site about performance. People often debate what would be the most efficient algorithm in C# to perform a task, or why Python is slow and Java is faster, etc. What I'm trying to understand is: why does this matter? There are specific areas of computing where I see why performance matters: games, where tens of thousands of computations are happening every second in a constant-update loop, or low level systems which other programs rely on, such as OSs and VMs, etc. But for the normal, typical high-level business app, why does performance matter? I can understand why it used to matter, decades ago. Computers were much slower and had much less memory, so you had to think carefully about these things. But today, we have so much memory to spare and computers are so fast: does it actually matter if a particular Java algorithm is O(n^2)? Will it actually make a difference for the end users of this typical business app? When you press a GUI button in a typical business app, and behind the scenes it invokes an O(n^2) algorithm, in these days of modern computing - do you actually feel the inefficiency? My question is split in two: In practice, today does performance matter in a typical normal business program? If it does, please give me real-world examples of places in such an application, where performance and optimizations are important.

  • Is "as long as it works" the norm?

    - by q303
    Hi, My last shop did not have a process. Agile essentially meant they did not have a plan at all about how to develop or manage their projects. It meant "hey, here's a ton of work. Go do it in two weeks. We're fast paced and agile." They released stuff that they knew had problems. They didn't care how things were written. There were no code reviews--despite there being several developers. They released software they knew to be buggy. At my previous job, people had the attitude as long as it works, it's fine. When I asked for a rewrite of some code I had written while we were essentially exploring the spec, they denied it. I wanted to rewrite the code because code was repeated in multiple places, there was no encapsulation and it took people a long time to make changes to it. So essentially, my impression is this: programming boils down to the following: Reading some book about the latest tool/technology Throwing code together based on this, avoiding writing any individual code because the company doesn't want to "maintain custom code" Showing it and moving on to the next thing, "as long as it works." I've always told myself that next job I'm going to get a better shop. It never happens. If this is it, then I feel stuck. The technologies always change; if the only professional development here is reading the latest MS Press technology book, then what have you built in 10 years but a superficial knowledge of various technologies? I'm concerned about: Best way to have professional standards How to develop meaningful knowledge and experience in this situation

  • Should mock objects for tests be created at a high or low level

    - by Danack
    When creating unit tests for those other objects, what is the best way to create mock objects that provide data to other objects. Should they be created at a 'high level' and intercept the calls as soon as possible, or should they be done at a 'low level' and so make as much as the real code still be called? e.g. I'm writing a test for some code that requires a NoteMapper object that allows Notes to be loaded from the DB. class NoteMapper { function getNote($sqlQueryFactory, $noteID) { // Create an SQL query from $sqlQueryFactory // Run that SQL // if null // return null // else // return new Note($dataFromSQLQuery) } } I could either mock this object at a high level by creating a mock NoteMapper object, so that there are no calls to the SQL at all e.g. class MockNoteMapper { function getNote($sqlQueryFactory, $noteID) { //$mockData = {'Test Note title', "Test note text" } // return new Note($mockData); } } Or I could do it at a very low level, by creating a MockSQLQueryFactory that instead of actually querying the database just provides mock data back, and passing that to the current NoteMapper object. It seems that creating mocks at a high level would be easier in the short term, but that in the long term doing it at a low level would be more powerful and possibly allow more automation of tests e.g. by recording data in an out of a DB and then replaying that data for tests. Is there a recommended way of creating mocks? Are there any hard and fast rules about which are better, or should they both be used where appropriate?

  • Is it common to lie in job ads regarding the technologies in use?

    - by Desolate Planet
    Wanted: Experienced Delphi programmer to maintain ginormous legacy application and assist in migration to C# Later on, as the new hire settles into his role... "Oh, that C# migration? Yeah, we'd love to do that. But management is dead-set against it. Good thing you love Pascal, eh?" I've noticed quite a lot of this where I live (Scotland) and I'm not sure how common this is across IT: a company is using a legacy technology and they know that most developers will avoid them to keep mainstream technology on their resumes. So, they will put out a advertisement saying they are looking to move their product to some hip new tech (C#, Ruby, FORTRAN 99) and require someone who has exposure to both - but the migration is just a carrot on a stick, perpetually hung in front of the hungry developer as he spends each day maintaining the legacy app. I've experienced this myself, and heard far too many similar stories to the point where it seems like common practice. I've learned over time that every company has legacy problems of some sort, but I fail to see why they can't be honest about it. It should be common sense to any developer that the technology in place is there to support the business and not the other way round. Unless the technology is hurting the business in someway, I hardly see any just cause for reworking the software stack to be made up whatever is currently vogue in the industry. Would you say that this is commonplace? If so, how can I detect these kinds of leading advertisements beforehand?

    - by Get Proactive Customer Adoption Team
    Untitled Document Catch the Express—Register for an Instructional Webcast Oracle Proactive Support’s ‘Get Proactive’ message to customers underscores the benefits they’ll obtain by leveraging the Prevent, Resolve and Upgrade capabilities available across the suite of Oracle Products. Our goal in Proactive Support is to show customers how to ‘Get Proactive’ and achieve success by leveraging the latest tools, knowledge, and best practices available to manage your applications and technology more proactively. Most importantly, we want to ensure that customers are proficient in the use of these proactive capabilities. To help you gain this proficiency, we’ve recently launched a series of instructional webcasts that we call the “Resolve Series.” This series consists of both live and on-demand webcasts, and features some of the key proactive capabilities that customers can leverage to resolve their own problems. We launched the first phase of the series in July, and focused on finding answers using the My Oracle Support portal. Among the topics covered in those sessions were best practices for searching the knowledge base, leveraging communities to find answers faster, and other proactive features of My Oracle Support The second phase of the series is set to kick off in September. This phase will include product specific sessions designed to provide customers who use the product with the skills and knowledge required to leverage some of the most important capabilities found under the “RESOLVE” category of our proactive portfolio on My Oracle Support. These webcasts will feature Subject Matter Experts demonstrating how to use the tools and capabilities, discussing best practices, and providing answers to any questions you might have. In addition, hands-on labs will be included in some of the sessions, allowing you to practice applying what you’ve just learned. Whether you are a new customer or you’ve worked with Oracle Support for years, you’ll discover new information and techniques to help you work more efficiently and keep your systems running smoothly. Leverage this opportunity to learn best practices and get the inside track on finding answers fast by using the right tools at the right time. Make sure to take advantage of these webcasts and maximize the value you receive from your Oracle Premier Support investment. See the full schedule of events and register for sessions.

  • Why maven so slow compared to automake?

    - by ???'Lenik
    I have a Maven project consists of around 100 modules. I have reason to decompose the project to so many modules, and I don't think I should merge them in order to speed up the build process. I have read a lot of projects by other people, e.g., the Maven project itself, and Apache Archiva, and Hudson project, they all consists of a lot of modules, nearly 100 maybe, more or less. The problem is, to build them all need so much time, 3 hours for the first time build (this is acceptable because a lot of artifacts to download), and 15 minutes for the second build (this is not acceptable). For automake, things are similarly, the first time you need to configure the project, to prepare the magical config.h file, it's far more complex then what maven does. But it's still fast, maybe 10 seconds on my Debian box. After then, make install requires maybe 10 minutes for the first time build. However, when everything get prepared, the .o object files are generated, they don't have to be rebuild at all for the second time build. (In Maven, everything rebuild at everytime.) I'm very wondering, how guys working for Maven projects can bare this long time for each build, I'm just can't sit down calmly during each time Maven build, it took too long time, really.
