  • CentOS 6 - YUM Local Repo - Ensure consistent package distribution

    - by Mike Purcell
    I've read a few guides outlining how to setup a local YUM repo, but none of them explicitly stated an answer to my question; If I set up a local YUM repo, does that mean that any CentOS servers which pull from said repo will never be "ahead" of the local YUM repo? I want to ensure a consistent package distribution across all my servers. Right now, when I do a yum update, even on a daily basis, the servers can be out of alignment. For example if I run YUM update on my dev server in the morning, then run YUM update on one of my production servers in the afternoon, the production server may have picked up a new version of a package that the dev server did not pick up, due to the time window between the update commands. Rather, I'd prefer that I run yum update from my dev server which has access to remote upstream yum repos, then let it sit for 2 weeks, after which I run yum update on my production servers against the local repo on my dev server.

  • Understanding Application binary interface (ABI)

    - by Tim
    I am trying to understand the concept of Application binary interface (ABI). From The Linux Kernel Primer: An ABI is a set of conventions that allows a linker to combine separately compiled modules into one unit without recompilation, such as calling conventions, machine interface, and operating-system interface. Among other things, an ABI defines the binary interface between these units. ... The benefits of conforming to an ABI are that it allows linking object files compiled by different compilers. From Wikipedia: an application binary interface (ABI) describes the low-level interface between an application (or any type of) program and the operating system or another application. ABIs cover details such as data type, size, and alignment; the calling convention, which controls how functions' arguments are passed and return values retrieved; the system call numbers and how an application should make system calls to the operating system; and in the case of a complete operating system ABI, the binary format of object files, program libraries and so on. I was wondering whether ABI depends on both the instruction set and the OS. Are the two all that ABI depends on? What kinds of role does ABI play in different stages of compilation: preprocessing, conversion of code from C to Assembly, conversion of code from Assembly to Machine code, and linking? From the first quote above, it seems to me that ABI is needed for only linking stage, not the other stages. Is it correct? When is ABI needed to be considered? Is ABI needed to be considered during programming in C, Assembly or other languages? If yes, how are ABI and API different? Or is it only for linker or compiler? Is ABI specified for/in machine code, Assembly language, and/or of C?

  • World Location issues with camera and particle

    - by Joe Weeks
    I have a bit of a strange question, I am adapting the existing code base including the tile engine as per the book: XNA 4.0 Game Development by example by Kurt Jaegers, particularly the aspect that I am working on is the part about the 2D platformer in the last couple of chapters. I am creating a platformer which has a scrolling screen (similar to an old school screen chase), I originally did not have any problems with this aspect as it is simply a case of updating the camera position on the X axis with game time, however I have since added a particle system to allow the players to fire weapons. This particle shot is updated via the world position, I have translated everything correctly in terms of the world position when the collisions are checked. The crux of the problem is that the collisions only work once the screen is static, whilst the camera is moving to follow the player, the collisions are offset and are hitting blocks that are no longer there. My collision for particles is as follows (There are two vertical and horizontal): protected override Vector2 horizontalCollisionTest(Vector2 moveAmount) { if (moveAmount.X == 0) return moveAmount; Rectangle afterMoveRect = CollisionRectangle; afterMoveRect.Offset((int)moveAmount.X, 0); Vector2 corner1, corner2; // new particle world alignment code. afterMoveRect = Camera.ScreenToWorld(afterMoveRect); // end. if (moveAmount.X < 0) { corner1 = new Vector2(afterMoveRect.Left, afterMoveRect.Top + 1); corner2 = new Vector2(afterMoveRect.Left, afterMoveRect.Bottom - 1); } else { corner1 = new Vector2(afterMoveRect.Right, afterMoveRect.Top + 1); corner2 = new Vector2(afterMoveRect.Right, afterMoveRect.Bottom - 1); } Vector2 mapCell1 = TileMap.GetCellByPixel(corner1); Vector2 mapCell2 = TileMap.GetCellByPixel(corner2); if (!TileMap.CellIsPassable(mapCell1) || !TileMap.CellIsPassable(mapCell2)) { moveAmount.X = 0; velocity.X = 0; } return moveAmount; } And the camera is pretty much the same as the one in the book... with this added (as an early test). public static void Update(GameTime gameTime) { position.X += 1; }

  • ZFS, dedupe and PST files

    - by Unreason
    I am interested to know what would be expected maximum dedupe ratio for a set of PST files. I have ~40G of pst files from ~15 usres with high level of duplication of attachments. I am running tests to see if I can have significant space savings if I store the data on ZFS with dedupe. For this purpose I have installed a test setup of Nexenta, but was wondering if someone here had already done this and what level of deduplication I might expect (or in another words how sensitive are pst files to block alignment and what are the parameters that can influence the ratio?). Initial test show very low dedupe ratio and I did find explanation that block level dedupe would not be efficient here and that byte level dedupe would be much better (and that it should be performed by application that is aware of internal organization), so I am just double checking here if someone have some more input. Otherwise I will probably be converting PST files to IMAP.

  • XML Rules Engine and Validation Tutorial with NIEM

    - by drrwebber
    Our new XML Validation Framework tutorial video is now available. See how to easily integrate code-free adaptive XML validation services into your web services using the Java CAMV validation engine. CAMV allows you to build fault tolerant content checking with XPath that optionally use SQL data lookups. This can provide warnings as well as error conditions to tailor your validation layer to exactly meet your business application needs. Also available is developing test suites using Apache ANT scripting of validations.  This allows a community to share sets of conformance checking test and tools . On the technical XML side the video introduces XPath validation rules and illustrates and the concepts of XML content and structure validation. CAM validation templates allow contextual parameter driven dynamic validation services to be implemented compared to using a static and brittle XSD schema approach.The SQL table lookup and code list validation are discussed and examples presented.Features are highlighted along with a demonstration of the interactive generation of actual live XML data from a SQL data store and then validation processing complete with errors and warnings detection.The presentation provides a primer for developing web service XML validation and integration into a SOA approach along with examples and resources. Also alignment with the NIEM IEPD process for interoperable information exchanges is discussed along with NIEM rules services.The CAMV engine is a high performance scalable Java component for rapidly implementing code-free validation services and methods. CAMV is a next generation WYSIWYG approach that builds from older Schematron coding based interpretative runtime tools and provides a simpler declarative metaphor for rules definition.

  • Aligning Numbered Bullet Points in Word 2007

    - by Frustratedwithbullets
    Hello, I am putting together a very large business manual which incorportaes numbered heading, steps to follow, diagrams, etc. When using the bullet points, they align perfectly as I work through the processes. However when I include a diagram, or something different from the "norm" of text, the alignment changes. I would like all the bullets points to be aligned in the whole document regardless of where they appear in the document. Is there a way to save the settings so that the bullets always appear in the same position? Currently I am having to reset the indents by dragging the tabs on the ruler. This will be a large document, so I don't want to manually adjust the numbered bullets every time. Help would be greatly appreciated. Thanks very much.

  • Photoshop: Trim a photo so it contains no transparent pixels?

    - by nickf
    In Photoshop, I've put together some panorama photos using the Photomerge tool and the resulting image contains a lot of transparent pixels. Also, because it's put together of multiple photos the alignment can be off. What I'd like to do is cut the image down to the largest box which contains no transparent pixels at all. It's similar to the Trim tool, but this would remove a number of non-transparent pixels. Is there anything like this? Basically something which would automatically crop the above image to the selection box there: a rectangle with no transparent pixels.

  • Google document does not print correctly on Mac 10.7.5 using Chrome

    - by Android Addict
    When attempting to print a Google document, the header does not get printed at all and the text starts almost in the center of the page - cutting off almost half of the text in the printable area horizontally. The vertical alignment appears fine, with the exception of hte missing header. I have searched the product forums at Google, but they are virtually unusable. Endless threads without a solution! For reference, the document prints fine from Windows XP using Chrome. I can also print from other applications on the Mac without issue - so I am thinking it's a Google doc issue at this point.

  • Make interchangeable class types via pointer casting only, without having to allocate any new objects?

    - by HostileFork
    UPDATE: I do appreciate "don't want that, want this instead" suggestions. They are useful, especially when provided in context of the motivating scenario. Still...regardless of goodness/badness, I've become curious to find a hard-and-fast "yes that can be done legally in C++11" vs "no it is not possible to do something like that". I want to "alias" an object pointer as another type, for the sole purpose of adding some helper methods. The alias cannot add data members to the underlying class (in fact, the more I can prevent that from happening the better!) All aliases are equally applicable to any object of this type...it's just helpful if the type system can hint which alias is likely the most appropriate. There should be no information about any specific alias that is ever encoded in the underlying object. Hence, I feel like you should be able to "cheat" the type system and just let it be an annotation...checked at compile time, but ultimately irrelevant to the runtime casting. Something along these lines: Node<AccessorFoo>* fooPtr = Node<AccessorFoo>::createViaFactory(); Node<AccessorBar>* barPtr = reinterpret_cast< Node<AccessorBar>* >(fooPtr); Under the hood, the factory method is actually making a NodeBase class, and then using a similar reinterpret_cast to return it as a Node<AccessorFoo>*. The easy way to avoid this is to make these lightweight classes that wrap nodes and are passed around by value. Thus you don't need casting, just Accessor classes that take the node handle to wrap in their constructor: AccessorFoo foo (NodeBase::createViaFactory()); AccessorBar bar (foo.getNode()); But if I don't have to pay for all that, I don't want to. That would involve--for instance--making a special accessor type for each sort of wrapped pointer (AccessorFooShared, AccessorFooUnique, AccessorFooWeak, etc.) Having these typed pointers being aliased for one single pointer-based object identity is preferable, and provides a nice orthogonality. So back to that original question: Node<AccessorFoo>* fooPtr = Node<AccessorFoo>::createViaFactory(); Node<AccessorBar>* barPtr = reinterpret_cast< Node<AccessorBar>* >(fooPtr); Seems like there would be some way to do this that might be ugly but not "break the rules". According to ISO14882:2011(e) 5.2.10-7: An object pointer can be explicitly converted to an object pointer of a different type.70 When a prvalue v of type "pointer to T1" is converted to the type "pointer to cv T2", the result is static_cast(static_cast(v)) if both T1 and T2 are standard-layout types (3.9) and the alignment requirements of T2 are no stricter than those of T1, or if either type is void. Converting a prvalue of type "pointer to T1" to the type "pointer to T2" (where T1 and T2 are object types and where the alignment requirements of T2 are no stricter than those of T1) and back to its original type yields the original pointer value. The result of any other such pointer conversion is unspecified. Drilling into the definition of a "standard-layout class", we find: has no non-static data members of type non-standard-layout-class (or array of such types) or reference, and has no virtual functions (10.3) and no virtual base classes (10.1), and has the same access control (clause 11) for all non-static data members, and has no non-standard-layout base classes, and either has no non-static data member in the most-derived class and at most one base class with non-static data members, or has no base classes with non-static data members, and has no base classes of the same type as the first non-static data member. Sounds like working with something like this would tie my hands a bit with no virtual methods in the accessors or the node. Yet C++11 apparently has std::is_standard_layout to keep things checked. Can this be done safely? Appears to work in gcc-4.7, but I'd like to be sure I'm not invoking undefined behavior.

  • Selling Federal Enterprise Architecture (EA)

    - by TedMcLaughlan
    Selling Federal Enterprise Architecture A taxonomy of subject areas, from which to develop a prioritized marketing and communications plan to evangelize EA activities within and among US Federal Government organizations and constituents. Any and all feedback is appreciated, particularly in developing and extending this discussion as a tool for use – more information and details are also available. "Selling" the discipline of Enterprise Architecture (EA) in the Federal Government (particularly in non-DoD agencies) is difficult, notwithstanding the general availability and use of the Federal Enterprise Architecture Framework (FEAF) for some time now, and the relatively mature use of the reference models in the OMB Capital Planning and Investment (CPIC) cycles. EA in the Federal Government also tends to be a very esoteric and hard to decipher conversation – early apologies to those who agree to continue reading this somewhat lengthy article. Alignment to the FEAF and OMB compliance mandates is long underway across the Federal Departments and Agencies (and visible via tools like PortfolioStat and ITDashboard.gov – but there is still a gap between the top-down compliance directives and enablement programs, and the bottom-up awareness and effective use of EA for either IT investment management or actual mission effectiveness. "EA isn't getting deep enough penetration into programs, components, sub-agencies, etc.", verified a panelist at the most recent EA Government Conference in DC. Newer guidance from OMB may be especially difficult to handle, where bottom-up input can't be accurately aligned, analyzed and reported via standardized EA discipline at the Agency level – for example in addressing the new (for FY13) Exhibit 53D "Agency IT Reductions and Reinvestments" and the information required for "Cloud Computing Alternatives Evaluation" (supporting the new Exhibit 53C, "Agency Cloud Computing Portfolio"). Therefore, EA must be "sold" directly to the communities that matter, from a coordinated, proactive messaging perspective that takes BOTH the Program-level value drivers AND the broader Agency mission and IT maturity context into consideration. Selling EA means persuading others to take additional time and possibly assign additional resources, for a mix of direct and indirect benefits – many of which aren't likely to be realized in the short-term. This means there's probably little current, allocated budget to work with; ergo the challenge of trying to sell an "unfunded mandate". Also, the concept of "Enterprise" in large Departments like Homeland Security tends to cross all kinds of organizational boundaries – as Richard Spires recently indicated by commenting that "...organizational boundaries still trump functional similarities. Most people understand what we're trying to do internally, and at a high level they get it. The problem, of course, is when you get down to them and their system and the fact that you're going to be touching them...there's always that fear factor," Spires said. It is quite clear to the Federal IT Investment community that for EA to meet its objective, understandable, relevant value must be measured and reported using a repeatable method – as described by GAO's recent report "Enterprise Architecture Value Needs To Be Measured and Reported". What's not clear is the method or guidance to sell this value. In fact, the current GAO "Framework for Assessing and Improving Enterprise Architecture Management (Version 2.0)", a.k.a. the "EAMMF", does not include words like "sell", "persuade", "market", etc., except in reference ("within Core Element 19: Organization business owner and CXO representatives are actively engaged in architecture development") to a brief section in the CIO Council's 2001 "Practical Guide to Federal Enterprise Architecture", entitled "3.3.1. Develop an EA Marketing Strategy and Communications Plan." Furthermore, Core Element 19 of the EAMMF is advised to be applied in "Stage 3: Developing Initial EA Versions". This kind of EA sales campaign truly should start much earlier in the maturity progress, i.e. in Stages 0 or 1. So, what are the understandable, relevant benefits (or value) to sell, that can find an agreeable, participatory audience, and can pave the way towards success of a longer-term, funded set of EA mechanisms that can be methodically measured and reported? Pragmatic benefits from a useful EA that can help overcome the fear of change? And how should they be sold? Following is a brief taxonomy (it's a taxonomy, to help organize SME support) of benefit-related subjects that might make the most sense, in creating the messages and organizing an initial "engagement plan" for evangelizing EA "from within". An EA "Sales Taxonomy" of sorts. We're not boiling the ocean here; the subjects that are included are ones that currently appear to be urgently relevant to the current Federal IT Investment landscape. Note that successful dialogue in these topics is directly usable as input or guidance for actually developing early-stage, "Fit-for-Purpose" (a DoDAF term) Enterprise Architecture artifacts, as prescribed by common methods found in most EA methodologies, including FEAF, TOGAF, DoDAF and our own Oracle Enterprise Architecture Framework (OEAF). The taxonomy below is organized by (1) Target Community, (2) Benefit or Value, and (3) EA Program Facet - as in: "Let's talk to (1: Community Member) about how and why (3: EA Facet) the EA program can help with (2: Benefit/Value)". Once the initial discussion targets and subjects are approved (that can be measured and reported), a "marketing and communications plan" can be created. A working example follows the Taxonomy.

Unanticipated – illuminating signals of future or non-symmetric risk; helping to "future-proof" 2.5.5.2. Anticipated – discovering the level of impact that matters 3. EA Program Facet (What parts of the EA can and should be communicated, using business or mission terms?) 3.1. Architecture Models – the visual tools to be created and used 3.1.1. Operating Architecture – the Business Operating Model/Architecture elements of the EA truly drive all other elements, plus expose communication channels 3.1.2. Use Of – how can the EA models be used, and how are they populated, from a reasonable, pragmatic yet compliant perspective? What are the core/minimal models required? What's the relationship of these models, with existing system models? 3.1.3. Scope – what level of granularity within the models, and what level of abstraction across the models, is likely to be most effective and useful? 3.2. Traceability – the maturity, status, completeness of the tools 3.2.1. Status – what in fact is the degree of maturity across the integrated EA model and other relevant governance models, and who may already be benefiting from it? 3.2.2. Visibility – how does the EA visibly and effectively prove IT investment performance goals are being reached, with positive mission outcome? 3.3. Governance – what's the interaction, participation method; how are the tools used? 3.3.1. Contributions – how is the EA program informed, accept submissions, collect data? Who are the experts? 3.3.2. Review – how is the EA validated, against what criteria?  Taxonomy Usage Example:   1. To speak with: a. ...a particular set of System Owners Facing Strategic Change, via mandate (like the "Cloud First" mandate); about... b. ...how the EA program's visible and easily accessible Infrastructure Reference Model (i.e. "IRM" or "TRM"), if updated more completely with current system data, can... c. ...help shed light on ways to mitigate risks and avoid future costs associated with NOT leveraging potentially-available shared services across the enterprise... 2. ....the following Marketing & Communications (Sales) Plan can be constructed: a. Create an easy-to-read "Consequence Model" that illustrates how adoption of a cloud capability (like elastic operational storage) can enable rapid and durable compliance with the mandate – using EA traceability. Traceability might be from the IRM to the ARM (that identifies reusable services invoking the elastic storage), and then to the PRM with performance measures (such as % utilization of purchased storage allocation) included in the OMB Exhibits; and b. Schedule a meeting with the Program Owners, timed during their Acquisition Strategy meetings in response to the mandate, to use the "Consequence Model" for advising them to organize a rapid and relevant RFI solicitation for this cloud capability (regarding alternatives for sourcing elastic operational storage); and c. Schedule a series of short "Discovery" meetings with the system architecture leads (as agreed by the Program Owners), to further populate/validate the "As-Is" models and frame the "To Be" models (via scenarios), to better inform the RFI, obtain the best feedback from the vendor community, and provide potential value for and avoid impact to all other programs and systems. --end example -- Note that communications with the intended audience should take a page out of the standard "Search Engine Optimization" (SEO) playbook, using keywords and phrases relating to "value" and "outcome" vs. "compliance" and "output". Searches in email boxes, internal and external search engines for phrases like "cost avoidance strategies", "mission performance metrics" and "innovation funding" should yield messages and content from the EA team. This targeted, informed, practical sales approach should result in additional buy-in and participation, additional EA information contribution and model validation, development of more SMEs and quick "proof points" (with real-life testing) to bolster the case for EA. The proof point here is a successful, timely procurement that satisfies not only the external mandate and external oversight review, but also meets internal EA compliance/conformance goals and therefore is more transparently useful across the community. In short, if sold effectively, the EA will perform and be recognized. EA won’t therefore be used only for compliance, but also (according to a validated, stated purpose) to directly influence decisions and outcomes.

  • NPOI set cell style "HSSFFont.BOLDWEIGHT_BOLD" is not working

    - by vandana sharma
    I'm using NPOI to output excel from Asp.Net. I want to set bold and normal style to my cell but it is working for few cell and not for remaining cell.Please have look on following example: Dim hssfworkbook As New HSSFWorkbook() Dim sheetOne As HSSFSheet = hssfworkbook.CreateSheet("Sheet1") hssfworkbook.CreateSheet("Sheet2") hssfworkbook.CreateSheet("Sheet3") Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle cellStyle.Alignment = HSSFCellStyle.ALIGN_CENTER Dim font As HSSFFont = _hssfworkbook.CreateFont() font.Boldweight = HSSFFont.BOLDWEIGHT_BOLD cellStyle.SetFont(font) For i = 0 To 9 Step 1 'I want to add cell style to these cells If i Mod 2 = 0 Then Sheet1.CreateRow(i).CreateCell(1).SetCellValue(i) font.Boldweight = HSSFFont.BOLDWEIGHT_BOLD cellStyle.SetFont(font) Sheet1.GetRow(i).GetCell(1).CellStyle = cellStyle Else Sheet1.CreateRow(i).CreateCell(1).SetCellValue(i) font.Boldweight = HSSFFont.BOLDWEIGHT_NORMAL cellStyle.SetFont(font) Sheet1.GetRow(i).GetCell(1).CellStyle = cellStyle End If Next Actually code is working fine but i don't know the particular situation from where and why its stops working for remaining few rows. Its not working properly for all cells and from that particular cell the bold and normal property stops working on whole sheet like sheet2 and sheet3.

  • Wireframe mock-up software

    - by Dave Jarvis
    Requirements Looking for wireframe mock-up software for web apps with the following constraints: Desktop application (supports Linux) (can be online) Export all pages to separate image files (PNG or SVG preferred) Template for all pages Drag and drop standard HTML widgets for <forms> Tabbed panels (that allow content on the different tabs) Shuttle controls Saves in an XML format (XSLT could convert to HTML) Widget alignment and resizing (relative to other widgets) Under $100.00 USD Examples That come close: Cacoo - Not a desktop application; does not have a true tabbed panel widget Pencil - Export feature has serious bugs (missing text); no template? Balsamiq - Installation proved cantankerous on Linux (due to Adobe AIR) Mockingbird - No shuttle controls; no auto-resize of widgets Pencil & paper - Not a good look for a formal document presented to clients Any others that meet the requirements?

  • IE7 left:%; bug

    - by YuriKolovsky
    I'm working on a project, I use the latest IETester, and I bumped into a IE7 specific alignment bug. view this in IE7 and then in any other browser, for example Firefox, IE8 and even IE6. Notice how the little "|" between the lower links is not visible in IE7, yet it looks fine in the other browsers. Removing the left:-100%; from on line 61 fixes the bug as seen here, but i need this "left" for positioning. Any help on what is causing this bug, or potential ideas on how to fix it much needed.

  • How can you centre an image within the image control in SQL Server Reporting Services 2008?

    - by Keith
    I have got an image in an image control on a report in SSRS 2008. The image is coming from an external source, and varies in width. I would like to centre the image within the control, but the image control does not have an equivalent of the text box's TextAlign property to allow right/left/center alignment to be done automatically. I have seen methods to dynamically calculate the amount of left padding as a hack to solve this, http://blogs.msdn.com/chrishays/archive/2004/10/27/CenteredImages.aspx, but the solution gives an error in SSRS 2008, perhaps not surprising given the age of the article. Has anybody got a solution to this for SSRS 2008?

  • Examples of good IDEs to analyze for custom Form/Report designer

    - by Paul Sasik
    I am working on a basic form/report designer. Some of the features i'm looking to implement are: Single or multiple selection of objects Alignment of objects (when several are selected) Same-sizing of objects (when several are selected) Moving/dragging of selected object(s) Selected object resizing in eight directions (using object grips) For features and look-and-feel I've analyzed and used a mixture of ideas from: MS Visual Studio 200x (most useful so far) Visio Crystal Reports My question is: Have I overlooked some other IDEs that provide these kinds of features that are better and user-friendlier examples of what to do than others i've looked at? (They don't have to be Microsoft products. That's just what i have ready access to.)

  • What is a robust jQuery Rich Text Editor with image upload capabilities?

    - by thinkswan
    I know this question has been asked countless times, but answers are mixed, so I thought I'd test the waters and see what the latest verdict is out in the development community. I need a [preferably jQuery] rich text editor plugin that simply attaches itself to <textarea> elements and supports image uploads. It doesn't need to be too advanced. Just alignment, bold, italic, styles and image support. I tried CKEditor (along with CKFinder for image uploads), but it just has too many features and is too heavy for what I need. This is going to be used for simple webpage editing.

  • Mobile iPhone - Multiple buttons in a row

    - by Thomas
    Hello all: I'm an iPhone developer, but new to web development. I've done some basic HTML websites and made one in iWeb as well. I'm trying to branch out to actual mobile development now, so I checked out Dashcode. Anyway, I'm trying to put a Call Button, Mail Button, and Map Button in horizontal alignment. I realize that I can add a Column Layout and have two buttons in a row, but that's the most I've gotten. Any ideas? Thanks! Thomas

  • IA-32: Pushing a byte onto a stack isn't possible on Pentium, why?

    - by Tim Green
    Hi, I've come to learn that you cannot push a byte directly onto the Intel Pentium's stack, can anyone explain this to me please? The reason that I've been given is because the esp register is word-addressable (or, that is the assumption in our model) and it must be an "even address". I would have assumed decrementing the value of some 32-bit binary number wouldn't mess with the alignment of the register, but apparently I don't understand enough. I have tried some NASM tests and come up that if I declare a variable (bite db 123) and push it on to the stack, esp is decremented by 4 (indicating that it pushed 32-bits?). But, "push byte bite" (sorry for my choice of variable names) will result in a kind error: test.asm:10: error: Unsupported non-32-bit ELF relocation Any words of wisdom would be greatly appreciated during this troubled time. I am first year undergraduate so sorry for my naivety in any of this. Tim
