  • LVM / Device Mapper maps wrong device

    - by DaDaDom
    Hi, I run a LVM setup on a raid1 created by mdadm. md2 is based on sda6 (major:minor 8:6) and sdb6 (8:22). md2 is partition 9:2. The VG on top of md2 has 4 LVs, var, home, usr, tmp. First the problem: While booting it seems as if the device mapper takes the wrong partition for the mapping! Immediately after boot the information is like ~# dmsetup table systemlvm-home: 0 4194304 linear 8:22 384 systemlvm-home: 4194304 16777216 linear 8:22 69206400 systemlvm-home: 20971520 8388608 linear 8:22 119538048 systemlvm-home: 29360128 6291456 linear 8:22 243270016 systemlvm-tmp: 0 2097152 linear 8:22 41943424 systemlvm-usr: 0 10485760 linear 8:22 20971904 systemlvm-var: 0 10485760 linear 8:22 10486144 systemlvm-var: 10485760 6291456 linear 8:22 4194688 systemlvm-var: 16777216 4194304 linear 8:22 44040576 systemlvm-var: 20971520 10485760 linear 8:22 31457664 systemlvm-var: 31457280 20971520 linear 8:22 48234880 systemlvm-var: 52428800 33554432 linear 8:22 85983616 systemlvm-var: 85983232 115343360 linear 8:22 127926656 ~# cat /proc/mdstat Personalities : [raid1] md2 : active (auto-read-only) raid1 sda6[0] 151798080 blocks [2/1] [U_] md0 : active raid1 sda1[0] sdb1[1] 96256 blocks [2/2] [UU] md1 : active raid1 sda2[0] sdb2[1] 2931776 blocks [2/2] [UU] I have to manually "lvchange -an" all LVs, add /dev/sdb6 back to the raid and reactivate the LVs, then all is fine. But it prevents me from automounting the partitions and obviously leads to a bunch of other problems. If everything works fine, the information is like ~$ cat /proc/mdstat Personalities : [raid1] md2 : active raid1 sdb6[1] sda6[0] 151798080 blocks [2/2] [UU] ... ~# dmsetup table systemlvm-home: 0 4194304 linear 9:2 384 systemlvm-home: 4194304 16777216 linear 9:2 69206400 systemlvm-home: 20971520 8388608 linear 9:2 119538048 systemlvm-home: 29360128 6291456 linear 9:2 243270016 systemlvm-tmp: 0 2097152 linear 9:2 41943424 systemlvm-usr: 0 10485760 linear 9:2 20971904 systemlvm-var: 0 10485760 linear 9:2 10486144 systemlvm-var: 10485760 6291456 linear 9:2 4194688 systemlvm-var: 16777216 4194304 linear 9:2 44040576 systemlvm-var: 20971520 10485760 linear 9:2 31457664 systemlvm-var: 31457280 20971520 linear 9:2 48234880 systemlvm-var: 52428800 33554432 linear 9:2 85983616 systemlvm-var: 85983232 115343360 linear 9:2 127926656 I think that LVM for some reason just "takes" /dev/sdb6 which is then missing in the raid. I tried almost all options in the lvm.conf but none seems to work. Below is some more information, like config files. Does anyone have any idea about what is going on here and how to prevent that? If you need any additional information, please let me know Thanks in advance!

  • Apache FOP - Table top and bottom borders missing pagebreak inside table

    - by Thomas
    I am using Apache FOP to generate a PDF from a XLS FO document. I have created a test XLS FO document that contains a table with collapsed borders that with several tall rows. One of the rows starts on one page and ends on the next and this works as expected. The problem is that the bottom border of the table on the first page is missing and the top border of the table on the second pages is also missing. Below is the sample XLS FO document. <?xml version="1.0" encoding="utf-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <!-- defines the layout master --> <fo:layout-master-set> <fo:simple-page-master master-name="first" page-height="29.7cm" page-width="21cm" margin-top="1cm" margin-bottom="2cm" margin-left="2.5cm" margin-right="2.5cm"> <fo:region-body margin-top="3cm"/> <fo:region-before extent="3cm"/> <fo:region-after extent="1.5cm"/> </fo:simple-page-master> </fo:layout-master-set> <!-- starts actual layout --> <fo:page-sequence master-reference="first"> <fo:title>Sample Doc</fo:title> <fo:flow flow-name="xsl-region-body" font-size="x-small" font="Times New Roman"> <!-- table start --> <fo:table table-layout="fixed" width="100%" border-collapse="collapse"> <fo:table-column column-width="35mm"/> <fo:table-column column-width="100mm"/> <fo:table-column column-width="20mm"/> <fo:table-body> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Columns 2</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 3</fo:block> </fo:table-cell> </fo:table-row> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Row 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Lorem Ipsum is simply dummy text of the printing and typesetting industry.

This works, but I need to use these functions for other things than fixing this issue so what I need to know is if there is an other sollution to the problem?

  • static block instance block java Order

    - by Rollerball
    Having read this question In what order are the different parts of a class initialized when a class is loaded in the JVM? and the related JLS. I would like to know in more detail why for example having class Animal (superclass) and class Dog (subclass) as following: class Animal { static{ System.out.println("This is Animal's static block speaking"): } { System.out.println("This is Animal's instance block speaking"); } class Dog{ static{ System.out.println("This is Dog's static block speaking"); } { System.out.println("This is Dog's instance block speaking"); } public static void main (String [] args) { Dog dog = new Dog(); } } Ok before instantiating a class its direct superclass needs to be initialized (therefore all the statics variables and block need to be executed). So basically the question is: Why after initializing the static variables and static blocks of the super class, control goes down to the subclass for static variables initialization rather then finishing off the initialization of also the instance member? The control goes like: superclass (Animal): static variables and static blocks subclass (Dog): static variables and static blocks superclass (Animal): instance variables and instance blocks sublcass (Dog):instance variables and instance blocks What is the reason why it is in this way rather than : superclass -> static members superclass -> instance members subclass -> static members sublcass-> instance members

  • Spring can commit Transaction in finally block with RunTimeException in try block [migrated]

    - by Chance Lai
    The project used Spring + Hibernate Sample code: public void method(){ try{ dao.saveA(entityA); throw RuntimeException; dao.saveB(entityB); }catch(RuntimeException e){ throw e; }finally{ dao.saveC(entityC) } } Finally, just entityC will be saved in database in test. I think saveA, saveB, saveC in the same transaction,they should not be committed. In this case, I want to know why entityC is committed. How does Spring do this in the finally block?

  • Introducing .NET 4.0 with Visual Studio 2010 by Alex Mackey - Book review

    - by Malisa L. Ncube
    Alex (http://simpleisbest.co.uk/) does a very good job in covering the new features of .NET 4.0 and Visual Studio 2010. His focus is on the developers that have experience in development using previous versions of Visual Studio, more specifically Visual Studio 2008.     The following are my views towards his book. 1. Scope / Coverage Even as the book is labeled as introduction, it is covers a broad spectrum of technologies, features and references that are focused into helping a developer quickly decide what to use in the new .NET framework. a. Content The content included covers as much as possible the new additions that are included in the new .NET version 4.0. He shows the Visual Studio 2010 new features and quickly shows how to extend it using Managed Extensibility Framework. Some of my favorites are parallel debugging enhancements. The author delves into JQuery, which Microsoft has decided to support. Some of the very interesting content is on the out-of-band releases including ASP.NET MVC, Windows Azure Silverlight 3 and WCF Data Services. b. What is not included? Windows Phone 7 Series. This was only talked about in the MIX10. The data may not have been available at the time of writing. Microsoft Pinpoint (Microsoft code name "Dallas") Windows Embedded development. c. Table of Contents Chapter 1: Introduction Chapter 2: Visual Studio IDE and MEF Chapter 3: Language and Dynamic Changes Chapter 4: CLR and BCL Changes Chapter 5: Parallelization and Threading Enhancements Chapter 6: Windows Workflow Foundation 4 Chapter 7: Windows Communication Foundation Chapter 8: Entity Framework Chapter 9: WCF Data Services Chapter 10: ASPNET Chapter 11: Microsoft AJAX Library Chapter 12: jQuery Chapter 13: ASPNET MVC Chapter 14: Silverlight Introduction Chapter 15: WPF 4.0 and Silverlight 3.0 Chapter 16: Windows Azure 2. Depth Avoids getting into depth on the topics presented, to present the new concepts in assumption of the developer’s existing knowledge. Code samples are on book and exist mostly as snippets and very easy to follow. There are no downloadable examples. 3. Complexity The book is written in a very simple way and easy to follow. There are no irrelevant intimidating details. So it’s a book that you can grab and never put down until you’ve finished reading the entire book. 4. References The author includes reference links to blogs, Wikis and a lot of online resources including the MSDN documentation, which is a very convenient strategy to avoid flooding the reader with details which may not be of interest to them. Most sites do not use url routing and that is really not nice. There are notes from interviews between the author and people behind the new technologies, in which they explain what some specific areas that need clarifications and what their future views are in relation to the features they are working on. 5. Target The author targets experts that want to make a transition from .NET 3.5 to 4.0. Some obvious 3.5 features have been purposely excluded from the text 6. Overrall It is evident that the author has made extensive research into the breadth of what MS is working on, in relation to .NET and Visual Studio and has also been watching the online community. What I would like to see in the next edition are some details on OData protocol, Expression Blend 4 and Embedded development and Windows Phone development. I should say I’m one of the beneficiaries of this book. Excellent work Alex.   Technorati Tags: .NET,Book-Review,Visual Studio

  • Drupal6: How to programmatically style a block?

    - by Fronker
    In Drupal6, I basically have a block (a hierarchical menu structure) that turns out like this in HTML: <div class="block block-menu_block" id="block-menu_block-1"> <div class="content"> <div class="menu-block-1 menu-name-menu-navigation parent-mlid-0 menu-level-1"> <ul class="menu"> <li class="leaf first menu-mlid-248 active active-trail"><a class="active-trail active" title="" href="/">Start</a></li> <li class="expanded menu-mlid-249 active"><a class="active" title="" href="/">Aktuell</a> <ul class="menu"> <li class="leaf first menu-mlid-259"> <a title="News und Presse" href="/news-und-presse">News and Press</a> </li>... What I would like to get is actually a lot simpler: <div id="topmenu"> <ul class="one"> <li>some main entry <ul> <li> some sub entry ... or maybe: <div id="topmenu"> <h2>some main entry</h2> <h3><a href="#">some sub entry</a></h3> <h3><a href="#">another sub entry</a></h3> <h2>another main entry</h2> So, keeping the structure, but being able to use simpler, even completely different tags, if and when needed. I think I understand from the drupal docs, that I am (maybe) looking at <div class="block block-menu_block" id="block-menu_block-1" ==> module := menu_block delta := 1 (?) regrettably, none of the suggested * block-[module]-[delta].tpl.php * block-[module].tpl.php * block-[region].tpl.php placed next to page.tpl.php has any impact (yes, I did clear the cache).

  • distributed, fault-tolerant network block device

    - by gucki
    I'm looking for a distributed, fault-tolerant network storage system which exposes block devices (not filesystems) on the clients. A client's block device should write simultaneously to several storage nodes A client's block device should not fail as long as not all storage nodes backing it went down The master should automatically redistribute storages' data when a storage node fails or gets added/ removed A single master (which is for metadata only) is fine So ideally the architecture would be very similar to moosefs (http://www.moosefs.org/) but instead of exposing a real filesystem mounted using a fuse client it'd expose block devices on the clients. I know of iscsi and drbd but both don't seem to offer what I'm looking for. Or am I missing something?

  • ruby block and returning something from block

    - by dorelal
    I am using ruby 1.8.7. p = lambda { return 10;} def lab(block) puts 'before' puts block.call puts 'after' end lab p Above code output is before 10 after I refactored same code into this def lab(&block) puts 'before' puts block.call puts 'after' end lab { return 10; } Now I am getting LocalJumpError: unexpected return. To me both the code are doing same thing. Yes in the first case I am passing a proc and in the second case I am passing a block. But &block converts that block into proc. So proc.call should behave same. And yes I have seen this post http://stackoverflow.com/questions/2325471/using-return-in-a-ruby-block

  • How to Block a HTTP Website along with Its All Subdomain using IPTABLE

    - by netnovice
    I run a small HTTP web proxy site . We can not modify anything there in Proxy program. Few users mainly use Yahoo Web mail for Spamming and We need to block yahoo web mail access only ( complete yahoo website is also Ok) through our proxy . specially .mail.yahoo.com.. Like - we need to block URL like - http://uk-mg61.mail.yahoo.com http://in-mg61.mail.yahoo.com etc. etc. Note : We generaly open http://mail.yahoo.com in browser - but after loggin in it forwards it to Urls like above but all those are subdomain of mail.yahoo.com My target is if we can get all IP list for all available subdomain of mail.yahoo.com I can block it totally . We can only use IPTABLE ...I know using proxy itself we can check HTTP header and check Host field for .mail.yahoo.com. and block it. Solution : Follwoign what I did using IPtable . I collected IP CIDR block for yahoo mainly for yahoo web mail ( mail.yahoo.com ) as much as possible ( using linux host and whois command ) [ like 66.163.160.0/19 nd 98.136.0.0/14 etc ] and applied follwing command Like iptables -A OUTPUT -p tcp -d 66.163.160.0/19 -m state --state NEW -j DROP etc. Things are working fine. user can not access yahoo mail BUT the problem is I need to be updated with the avaialble CIDR YAHOO IP list ... I am ready to do it every week. I collected many from Net... You know theer are countles subdomain of mail.yahoo.com and seems every week Yahoo adding new IP... But what I observed some time user can bypass our rule and the reason obvously all the avaialble Ips are not entered in IPtable yet. What we need to do is enter all Ips of mail.yahoo.co But where do I find all subdomain for mail.yahoo.com I know we can get it from DNS but I must not be allowed to make DNS axfr query. Also doing reverse DNS will have performance issue. I want to know all subdomain of .mail.yahoo.c Can I get it from yahoo site. I have the list of all YAHOO smtp IP....but I need webmail Ip... ( http://public.yahoo.com/carloc/ymail.html ) Can you please share your Idea. Thank you

  • Red Gate Coder interviews: Alex Davies

    - by Michael Williamson
    Alex Davies has been a software engineer at Red Gate since graduating from university, and is currently busy working on .NET Demon. We talked about tackling parallel programming with his actors framework, a scientific approach to debugging, and how JavaScript is going to affect the programming languages we use in years to come. So, if we start at the start, how did you get started in programming? When I was seven or eight, I was given a BBC Micro for Christmas. I had asked for a Game Boy, but my dad thought it would be better to give me a proper computer. For a year or so, I only played games on it, but then I found the user guide for writing programs in it. I gradually started doing more stuff on it and found it fun. I liked creating. As I went into senior school I continued to write stuff on there, trying to write games that weren’t very good. I got a real computer when I was fourteen and found ways to write BASIC on it. Visual Basic to start with, and then something more interesting than that. How did you learn to program? Was there someone helping you out? Absolutely not! I learnt out of a book, or by experimenting. I remember the first time I found a loop, I was like “Oh my God! I don’t have to write out the same line over and over and over again any more. It’s amazing!” When did you think this might be something that you actually wanted to do as a career? For a long time, I thought it wasn’t something that you would do as a career, because it was too much fun to be a career. I thought I’d do chemistry at university and some kind of career based on chemical engineering. And then I went to a careers fair at school when I was seventeen or eighteen, and it just didn’t interest me whatsoever. I thought “I could be a programmer, and there’s loads of money there, and I’m good at it, and it’s fun”, but also that I shouldn’t spoil my hobby. Now I don’t really program in my spare time any more, which is a bit of a shame, but I program all the rest of the time, so I can live with it. Do you think you learnt much about programming at university? Yes, definitely! I went into university knowing how to make computers do anything I wanted them to do. However, I didn’t have the language to talk about algorithms, so the algorithms course in my first year was massively important. Learning other language paradigms like functional programming was really good for breadth of understanding. Functional programming influences normal programming through design rather than actually using it all the time. I draw inspiration from it to write imperative programs which I think is actually becoming really fashionable now, but I’ve been doing it for ages. I did it first! There were also some courses on really odd programming languages, a bit of Prolog, a little bit of C. Having a little bit of each of those is something that I would have never done on my own, so it was important. And then there are knowledge-based courses which are about not programming itself but things that have been programmed like TCP. Those are really important for examples for how to approach things. Did you do any internships while you were at university? Yeah, I spent both of my summers at the same company. I thought I could code well before I went there. Looking back at the crap that I produced, it was only surpassed in its crappiness by all of the other code already in that company. I’m so much better at writing nice code now than I used to be back then. Was there just not a culture of looking after your code? There was, they just didn’t hire people for their abilities in that area. They hired people for raw IQ. The first indicator of it going wrong was that they didn’t have any computer scientists, which is a bit odd in a programming company. But even beyond that they didn’t have people who learnt architecture from anyone else. Most of them had started straight out of university, so never really had experience or mentors to learn from. There wasn’t the experience to draw from to teach each other. In the second half of my second internship, I was being given tasks like looking at new technologies and teaching people stuff. Interns shouldn’t be teaching people how to do their jobs! All interns are going to have little nuggets of things that you don’t know about, but they shouldn’t consistently be the ones who know the most. It’s not a good environment to learn. I was going to ask how you found working with people who were more experienced than you… When I reached Red Gate, I found some people who were more experienced programmers than me, and that was difficult. I’ve been coding since I was tiny. At university there were people who were cleverer than me, but there weren’t very many who were more experienced programmers than me. During my internship, I didn’t find anyone who I classed as being a noticeably more experienced programmer than me. So, it was a shock to the system to have valid criticisms rather than just formatting criticisms. However, Red Gate’s not so big on the actual code review, at least it wasn’t when I started. We did an entire product release and then somebody looked over all of the UI of that product which I’d written and say what they didn’t like. By that point, it was way too late and I’d disagree with them. Do you think the lack of code reviews was a bad thing? I think if there’s going to be any oversight of new people, then it should be continuous rather than chunky. For me I don’t mind too much, I could go out and get oversight if I wanted it, and in those situations I felt comfortable without it. If I was managing the new person, then maybe I’d be keener on oversight and then the right way to do it is continuously and in very, very small chunks. Have you had any significant projects you’ve worked on outside of a job? When I was a teenager I wrote all sorts of stuff. I used to write games, I derived how to do isomorphic projections myself once. I didn’t know what the word was so I couldn’t Google for it, so I worked it out myself. It was horrifically complicated. But it sort of tailed off when I started at university, and is now basically zero. If I do side-projects now, they tend to be work-related side projects like my actors framework, NAct, which I started in a down tools week. Could you explain a little more about NAct? It is a little C# framework for writing parallel code more easily. Parallel programming is difficult when you need to write to shared data. Sometimes parallel programming is easy because you don’t need to write to shared data. When you do need to access shared data, you could just have your threads pile in and do their work, but then you would screw up the data because the threads would trample on each other’s toes. You could lock, but locks are really dangerous if you’re using more than one of them. You get interactions like deadlocks, and that’s just nasty. Actors instead allows you to say this piece of data belongs to this thread of execution, and nobody else can read it. If you want to read it, then ask that thread of execution for a piece of it by sending a message, and it will send the data back by a message. And that avoids deadlocks as long as you follow some obvious rules about not making your actors sit around waiting for other actors to do something. There are lots of ways to write actors, NAct allows you to do it as if it was method calls on other objects, which means you get all the strong type-safety that C# programmers like. Do you think that this is suitable for the majority of parallel programming, or do you think it’s only suitable for specific cases? It’s suitable for most difficult parallel programming. If you’ve just got a hundred web requests which are all independent of each other, then I wouldn’t bother because it’s easier to just spin them up in separate threads and they can proceed independently of each other. But where you’ve got difficult parallel programming, where you’ve got multiple threads accessing multiple bits of data in multiple ways at different times, then actors is at least as good as all other ways, and is, I reckon, easier to think about. When you’re using actors, you presumably still have to write your code in a different way from you would otherwise using single-threaded code. You can’t use actors with any methods that have return types, because you’re not allowed to call into another actor and wait for it. If you want to get a piece of data out of another actor, then you’ve got to use tasks so that you can use “async” and “await” to await asynchronously for it. But other than that, you can still stick things in classes so it’s not too different really. Rather than having thousands of objects with mutable state, you can use component-orientated design, where there are only a few mutable classes which each have a small number of instances. Then there can be thousands of immutable objects. If you tend to do that anyway, then actors isn’t much of a jump. If I’ve already built my system without any parallelism, how hard is it to add actors to exploit all eight cores on my desktop? Usually pretty easy. If you can identify even one boundary where things look like messages and you have components where some objects live on one side and these other objects live on the other side, then you can have a granddaddy object on one side be an actor and it will parallelise as it goes across that boundary. Not too difficult. If we do get 1000-core desktop PCs, do you think actors will scale up? It’s hard. There are always in the order of twenty to fifty actors in my whole program because I tend to write each component as actors, and I tend to have one instance of each component. So this won’t scale to a thousand cores. What you can do is write data structures out of actors. I use dictionaries all over the place, and if you need a dictionary that is going to be accessed concurrently, then you could build one of those out of actors in no time. You can use queuing to marshal requests between different slices of the dictionary which are living on different threads. So it’s like a distributed hash table but all of the chunks of it are on the same machine. That means that each of these thousand processors has cached one small piece of the dictionary. I reckon it wouldn’t be too big a leap to start doing proper parallelism. Do you think it helps if actors get baked into the language, similarly to Erlang? Erlang is excellent in that it has thread-local garbage collection. C# doesn’t, so there’s a limit to how well C# actors can possibly scale because there’s a single garbage collected heap shared between all of them. When you do a global garbage collection, you’ve got to stop all of the actors, which is seriously expensive, whereas in Erlang garbage collections happen per-actor, so they’re insanely cheap. However, Erlang deviated from all the sensible language design that people have used recently and has just come up with crazy stuff. You can definitely retrofit thread-local garbage collection to .NET, and then it’s quite well-suited to support actors, even if it’s not baked into the language. Speaking of language design, do you have a favourite programming language? I’ll choose a language which I’ve never written before. I like the idea of Scala. It sounds like C#, only with some of the niggles gone. I enjoy writing static types. It means you don’t have to writing tests so much. When you say it doesn’t have some of the niggles? C# doesn’t allow the use of a property as a method group. It doesn’t have Scala case classes, or sum types, where you can do a switch statement and the compiler checks that you’ve checked all the cases, which is really useful in functional-style programming. Pattern-matching, in other words. That’s actually the major niggle. C# is pretty good, and I’m quite happy with C#. And what about going even further with the type system to remove the need for tests to something like Haskell? Or is that a step too far? I’m quite a pragmatist, I don’t think I could deal with trying to write big systems in languages with too few other users, especially when learning how to structure things. I just don’t know anyone who can teach me, and the Internet won’t teach me. That’s the main reason I wouldn’t use it. If I turned up at a company that writes big systems in Haskell, I would have no objection to that, but I wouldn’t instigate it. What about things in C#? For instance, there’s contracts in C#, so you can try to statically verify a bit more about your code. Do you think that’s useful, or just not worthwhile? I’ve not really tried it. My hunch is that it needs to be built into the language and be quite mathematical for it to work in real life, and that doesn’t seem to have ended up true for C# contracts. I don’t think anyone who’s tried them thinks they’re any good. I might be wrong. On a slightly different note, how do you like to debug code? I think I’m quite an odd debugger. I use guesswork extremely rarely, especially if something seems quite difficult to debug. I’ve been bitten spending hours and hours on guesswork and not being scientific about debugging in the past, so now I’m scientific to a fault. What I want is to see the bug happening in the debugger, to step through the bug happening. To watch the program going from a valid state to an invalid state. When there’s a bug and I can’t work out why it’s happening, I try to find some piece of evidence which places the bug in one section of the code. From that experiment, I binary chop on the possible causes of the bug. I suppose that means binary chopping on places in the code, or binary chopping on a stage through a processing cycle. Basically, I’m very stupid about how I debug. I won’t make any guesses, I won’t use any intuition, I will only identify the experiment that’s going to binary chop most effectively and repeat rather than trying to guess anything. I suppose it’s quite top-down. Is most of the time then spent in the debugger? Absolutely, if at all possible I will never debug using print statements or logs. I don’t really hold much stock in outputting logs. If there’s any bug which can be reproduced locally, I’d rather do it in the debugger than outputting logs. And with SmartAssembly error reporting, there’s not a lot that can’t be either observed in an error report and just fixed, or reproduced locally. And in those other situations, maybe I’ll use logs. But I hate using logs. You stare at the log, trying to guess what’s going on, and that’s exactly what I don’t like doing. You have to just look at it and see does this look right or wrong. We’ve covered how you get to grip with bugs. How do you get to grips with an entire codebase? I watch it in the debugger. I find little bugs and then try to fix them, and mostly do it by watching them in the debugger and gradually getting an understanding of how the code works using my process of binary chopping. I have to do a lot of reading and watching code to choose where my slicing-in-half experiment is going to be. The last time I did it was SmartAssembly. The old code was a complete mess, but at least it did things top to bottom. There wasn’t too much of some of the big abstractions where flow of control goes all over the place, into a base class and back again. Code’s really hard to understand when that happens. So I like to choose a little bug and try to fix it, and choose a bigger bug and try to fix it. Definitely learn by doing. I want to always have an aim so that I get a little achievement after every few hours of debugging. Once I’ve learnt the codebase I might be able to fix all the bugs in an hour, but I’d rather be using them as an aim while I’m learning the codebase. If I was a maintainer of a codebase, what should I do to make it as easy as possible for you to understand? Keep distinct concepts in different places. And name your stuff so that it’s obvious which concepts live there. You shouldn’t have some variable that gets set miles up the top of somewhere, and then is read miles down to choose some later behaviour. I’m talking from a very much SmartAssembly point of view because the old SmartAssembly codebase had tons and tons of these things, where it would read some property of the code and then deal with it later. Just thousands of variables in scope. Loads of things to think about. If you can keep concepts separate, then it aids me in my process of fixing bugs one at a time, because each bug is going to more or less be understandable in the one place where it is. And what about tests? Do you think they help at all? I’ve never had the opportunity to learn a codebase which has had tests, I don’t know what it’s like! What about when you’re actually developing? How useful do you find tests in finding bugs or regressions? Finding regressions, absolutely. Running bits of code that would be quite hard to run otherwise, definitely. It doesn’t happen very often that a test finds a bug in the first place. I don’t really buy nebulous promises like tests being a good way to think about the spec of the code. My thinking goes something like “This code works at the moment, great, ship it! Ah, there’s a way that this code doesn’t work. Okay, write a test, demonstrate that it doesn’t work, fix it, use the test to demonstrate that it’s now fixed, and keep the test for future regressions.” The most valuable tests are for bugs that have actually happened at some point, because bugs that have actually happened at some point, despite the fact that you think you’ve fixed them, are way more likely to appear again than new bugs are. Does that mean that when you write your code the first time, there are no tests? Often. The chance of there being a bug in a new feature is relatively unaffected by whether I’ve written a test for that new feature because I’m not good enough at writing tests to think of bugs that I would have written into the code. So not writing regression tests for all of your code hasn’t affected you too badly? There are different kinds of features. Some of them just always work, and are just not flaky, they just continue working whatever you throw at them. Maybe because the type-checker is particularly effective around them. Writing tests for those features which just tend to always work is a waste of time. And because it’s a waste of time I’ll tend to wait until a feature has demonstrated its flakiness by having bugs in it before I start trying to test it. You can get a feel for whether it’s going to be flaky code as you’re writing it. I try to write it to make it not flaky, but there are some things that are just inherently flaky. And very occasionally, I’ll think “this is going to be flaky” as I’m writing, and then maybe do a test, but not most of the time. How do you think your programming style has changed over time? I’ve got clearer about what the right way of doing things is. I used to flip-flop a lot between different ideas. Five years ago I came up with some really good ideas and some really terrible ideas. All of them seemed great when I thought of them, but they were quite diverse ideas, whereas now I have a smaller set of reliable ideas that are actually good for structuring code. So my code is probably more similar to itself than it used to be back in the day, when I was trying stuff out. I’ve got more disciplined about encapsulation, I think. There are operational things like I use actors more now than I used to, and that forces me to use immutability more than I used to. The first code that I wrote in Red Gate was the memory profiler UI, and that was an actor, I just didn’t know the name of it at the time. I don’t really use object-orientation. By object-orientation, I mean having n objects of the same type which are mutable. I want a constant number of objects that are mutable, and they should be different types. I stick stuff in dictionaries and then have one thing that owns the dictionary and puts stuff in and out of it. That’s definitely a pattern that I’ve seen recently. I think maybe I’m doing functional programming. Possibly. It’s plausible. If you had to summarise the essence of programming in a pithy sentence, how would you do it? Programming is the form of art that, without losing any of the beauty of architecture or fine art, allows you to produce things that people love and you make money from. So you think it’s an art rather than a science? It’s a little bit of engineering, a smidgeon of maths, but it’s not science. Like architecture, programming is on that boundary between art and engineering. If you want to do it really nicely, it’s mostly art. You can get away with doing architecture and programming entirely by having a good engineering mind, but you’re not going to produce anything nice. You’re not going to have joy doing it if you’re an engineering mind. Architects who are just engineering minds are not going to enjoy their job. I suppose engineering is the foundation on which you build the art. Exactly. How do you think programming is going to change over the next ten years? There will be an unfortunate shift towards dynamically-typed languages, because of JavaScript. JavaScript has an unfair advantage. JavaScript’s unfair advantage will cause more people to be exposed to dynamically-typed languages, which means other dynamically-typed languages crop up and the best features go into dynamically-typed languages. Then people conflate the good features with the fact that it’s dynamically-typed, and more investment goes into dynamically-typed languages. They end up better, so people use them. What about the idea of compiling other languages, possibly statically-typed, to JavaScript? It’s a reasonable idea. I would like to do it, but I don’t think enough people in the world are going to do it to make it pick up. The hordes of beginners are the lifeblood of a language community. They are what makes there be good tools and what makes there be vibrant community websites. And any particular thing which is the same as JavaScript only with extra stuff added to it, although it might be technically great, is not going to have the hordes of beginners. JavaScript is always to be quickest and easiest way for a beginner to start programming in the browser. And dynamically-typed languages are great for beginners. Compilers are pretty scary and beginners don’t write big code. And having your errors come up in the same place, whether they’re statically checkable errors or not, is quite nice for a beginner. If someone asked me to teach them some programming, I’d teach them JavaScript. If dynamically-typed languages are great for beginners, when do you think the benefits of static typing start to kick in? The value of having a statically typed program is in the tools that rely on the static types to produce a smooth IDE experience rather than actually telling me my compile errors. And only once you’re experienced enough a programmer that having a really smooth IDE experience makes a blind bit of difference, does static typing make a blind bit of difference. So it’s not really about size of codebase. If I go and write up a tiny program, I’m still going to get value out of writing it in C# using ReSharper because I’m experienced with C# and ReSharper enough to be able to write code five times faster if I have that help. Any other visions of the future? Nobody’s going to use actors. Because everyone’s going to be running on single-core VMs connected over network-ready protocols like JSON over HTTP. So, parallelism within one operating system is going to die. But until then, you should use actors. More Red Gater Coder interviews

  • Block a URL at browser level

    - by Farseeker
    Does anyone have a solution (that doesn't involve editing the hosts file) to block a particular URL from FireFox? Basic back story is that I'm trying to discipline myself. I'm spending FAR too much time over at Server Fault that I want to genuinely block the site from my work PC so that every time I find myself flicking to it during work time I can't see it, but I'd like to be able to disable it during my lunch break. (So I only spend 40 minutes a day there, rather than 4 hours). That said I don't want to block it at the router, nor for anyone else.

  • export block device over network without root

    - by dschatz
    I'm trying to export a file as a block device over the network. I do not have root access on the machine where the file exists. I do have root access on the machine(s) where I will mount the block device. I've seen ATA-Over-Ethernet and ISCSI but there don't seem to be any implementations which allow me to export the block without root at least (some even require kernel modules). Is there an implementation of either of these or some other protocol that doesn't require root? Perhaps I can tunnel ethernet over IP to do this?

    How can i block a sub-site of a website as e.g. http://example.com/someSite unfortunately the hosts file is not an option since you can only block whole domains there and any "/" just destroys these rules. this is just for my personal protection against visiting some sites too often, while i still have to be able to get to the other sites of that domain (as e.g. example.com/someOtherSite) would be great if someone knows a solution regarding this topic

  • Ruby - Possible to pass a block as a param as an actual block to another function?

    - by Markus O'Reilly
    This is what I'm trying to do: def call_block(in_class = "String", &block) instance = eval("#{in_class}.new") puts "instance class: #{instance.class}" instance.instance_eval{ block.call } end # --- TEST EXAMPLE --- # This outputs "class: String" every time "sdlkfj".instance_eval { puts "class: #{self.class}" } # This will only output "class: Object" every time # I'm trying to get this to output "class: String" though call_block("String") { puts "class: #{self.class}" } On the line where it says "instance.instance_eval{ block.call }", I'm trying to find another way to make the new instance variable run instance eval on the block. The only way I can think of to get it to do that is to pass instance_eval the original block, not as a variable or anything, but as a real block like in the test example. Any tips?

  • Blocking a country (mass iP Ranges), best practice for the actual block

    - by kwiksand
    Hi all, This question has obviously been asked many times in many different forms, but I can't find an actual answer to the specific plan I've got. We run a popular European Commercial deals site, and are getting a large amount of incoming registrations/traffic from countries who cannot even take part in the deals we offer (and many of the retailers aren't even known outside Western Europe). I've identified the problem area to block a lot of this traffic, but (as expected) there are thousands of ip ranges required. My question now (finally!). On a test server, I created a script to block each range within iptables, but the amount of time it took to add the rules was large, and then iptables was unresponsive after this (especially when attempting a iptables -L). What is the most efficient way of blocking large numbers of ip ranges: iptables? Or a plugin where I can preload them efficiantly? hosts.deny? .htaccess (nasty as I'd be running it in apache on every load balanced web server)? Cheers

  • Postfix block senders outside from local domains

    - by Tibor Peter Toth
    I would like to block every mail that is coming in from a domain that is running on my server. Example: I have domain1.com on my mail server and I'm getting a mail from outside with an email address of [email protected] Then I know it's a Spam, because domain1.com is on my server, so the sender cannot come from outside. I want postfix to check for this, and simply block these kind of emails. I know this is a function in postfix, just don't know which one. Thanks.
