  • What are the advantages of OSPF vs nexthop self with iBGP?

    - by Matt Hamilton
    Assuming I have a fairly small network internally, but I have 4 routers each connected out to a different network. The routers are all sat next to each other connected via a switch. Each router uses BGP to speak to the outside networks. There is an iBGP mesh for each router to exchange the routes internally it knows about from each external network. The usual setup is to use OSPF to distribute the connected routes, as the routes via iBGP will still have the next hop set to their original value. What is the advantage of using OSPF in this scenario versus simply using 'set nexthop self' on the routes?

  • Macbook Pro 2010 13,3'' 2,4 vs. 2,66Ghz

    - by Milde
    Hi, is the 13,3'' MBP 2,66ghz worth the extra 300€, comparing it to the 2,4ghz version? What CPUs are installed? P8600/P8800 ? 300€ for 70GB more space and 0,26ghz or would it be better to use the 300€ for a solid state disk? What's your opinion? Thanks in advance, Milde

  • What explains the term orthogonal in a more non-nerd fashion?

    - by dontWatchMyProfile
    For example: Cardinality and optionality are orthogonal properties of a relationship. You can specify that a relationship is optional, even if you have specified upper and/or lower bounds. This means that there do not have to be any objects at the destination, but if there are then the number of objects must lie within the bounds specified. What exactly does "orthogonal" mean? I bet it's just a fancy soundig nerd-style word for something that could be expressed a lot easier to understand for average people ;) From wikipedia: In mathematics, two vectors are orthogonal if they are perpendicular, i.e., they form a right angle. The word comes from the Greek ????? (orthos), meaning "straight", and ????a (gonia), meaning "angle". Anyone?

  • Concise C# code for gathering several properties with a non-null value into a collection?

    - by stakx
    A fairly basic problem for a change. Given a class such as this: public class X { public T A; public T B; public T C; ... // (other fields, properties, and methods are not of interest here) } I am looking for a concise way to code a method that will return all A, B, C, ... that are not null in an enumerable collection. (Assume that declaring these fields as an array is not an option.) public IEnumerable<T> GetAllNonNullAs(this X x) { // ? } The obvious implementation of this method would be: public IEnumerable<T> GetAllNonNullAs(this X x) { var resultSet = new List<T>(); if (x.A != null) resultSet.Add(x.A); if (x.B != null) resultSet.Add(x.B); if (x.C != null) resultSet.Add(x.C); ... return resultSet; } What's bothering me here in particular is that the code looks verbose and repetitive, and that I don't know the initial List capacity in advance. It's my hope that there is a more clever way, probably something involving the ?? operator? Any ideas?

  • Calculating RAM Performance? Example: DDR3-2133 CL9-11-10-28 1.65V vs DDR3-1600 CL10-10-10-30 1.5V

    - by user1131467
    How do you calculate the relative performance of PC RAM? For example, what is the relative performance of the following: G.Skill Ripjaws Z 8 x 4GB Kit, DDR3-2133, [email protected] G.Skill Ripjaws Z 4 x 8GB Kit, DDR3-1600, [email protected] If it's relevant, when they are used in a top of the line ASUS Rampage IV Extreme motherboard and Intel i7 3960X? By performance, I mean relative: read latency write latency read bandwidth write bandwidth Please include working. (I mean how did you arrive at the figures based on timing and DDR3-speed)

  • Servers at remote sites vs. centralized servers?

    - by Boden
    Looking for some opinions here. We've got three physical locations and site-to-site VPN between all three. Currently we've got Windows domain controllers at each location, with roughly 50 clients at each. The domains are currently separate, and we're looking at integrating the three sites. Email (Exchange) will be located at the primary site, and RPD is already being used at the secondary branches to hit the app servers also located at the primary site. The bulk of the local user load at the other two sites is just file sharing. What would the main benefits and drawbacks be of replacing the local domain controllers with NAS devices, and only keeping the domain controller(s) at the primary site? (assuming upgrades are coming regardless) Under what circumstances would you choose one setup over the other?

  • Java: creating objects of arrays with different names at runtime and accessing/updating them

    - by scriptingalias
    Hello, I'm trying to create a class that can instantiate arrays at runtime by giving each array a "name" created by the createtempobjectname() method. I'm having trouble making this program run. I would also like to see how I could access specific objects that were created during runtime and accessing those arrays by either changing value or accessing them. This is my mess so far, which compiles but gets a runtime exception. import java.lang.reflect.Array; public class arrays { private static String temp; public static int name = 0; public static Object o; public static Class c; public static void main(String... args) { assignobjectname(); //getclassname();//this is supposed to get the name of the object and somehow //allow the arrays to become updated using more code? } public static void getclassname() { String s = c.getName(); System.out.println(s); } public static void assignobjectname()//this creates the object by the name returned { //createtempobjectname() try { String object = createtempobjectname(); c = Class.forName(object); o = Array.newInstance(c, 20); } catch (ClassNotFoundException exception) { exception.printStackTrace(); } } public static String createtempobjectname() { name++; temp = Integer.toString(name); return temp; } }

  • Any C/C++ to non-native bytecode compiler/interpreters?

    - by Matt
    As the title indicates, are there any C/C++ bytecode compilers/interpreters? I'm writing an application in an interpreted language that depends on certain libraries that are fully cross-compilable (there are no special flags to indicate code changes during compilation for a certain platform) but are written in C and C++. Rather than shipping n-platform-specific-libs with each platform, it would be nice to ship one set of libs which are interpreted by one platform specific interpreter. Possible and/or available?

  • How do I create a non-editable GXT ComboBox?

    - by VogonPoet
    I'm using GWT/GXT and trying to create a "normal" ComboBox - one that you cannot type in, but you can type a single character and it will automatically go to the first item in the list that starts with that letter. So, I don't want it READONLY, I want it so that you cannot replace the text in it with your own text (can't type characters into it). I cannot figure out how to get ComboBox or SimpleComboBox to do this. I've tried every combination of settings on it to no avail. I did see there is a GXT ListBox, but i need a component that extends from Field. Is there really no way to do this or am I missing something?

  • Windows Server 2008 R2 - 180 day evaluation vs. 10 days + 5 re-arms

    - by Rob
    The content on the Server 2008 R2 Trial Software page states that it can be evaluated for upto 180 days, however on a test machine we installed last week, it's requesting "re-arming" every 10 days, which seems to be do-able a maximum of 5 times? How do we get it to last more than 50 days, as it'd be a pain to have to rebuild the server concerned!

  • External Storage for 2TB of backups and 4TB of data RAID level? HW vs Software?

    - by Jerry Mayers
    I have a Mac Mini set up as a media center/file server. Currently I just have a hodgepodge mess of external drives for storage. I'm maxed out, and I have some new laptops on the way with much larger drives and I need to work out a good storage solution for backing them up, as well as storing media on the server. I need around 2 TB of storage for the time machine backups from my various systems and around 2 TB more for media. I would like to build this to handle around 6 TB total so I have some growing room. Since I'm using a Mac Mini as the server I need to use external enclosure(s) that support USB 2 or Firewire 800 (preferred) or gigabit Ethernet. Performance of the system isn't a huge concern since the majority of the access from other computers is done over 802.11N. I plan on using 2TB drives, for the final version, but initially I'll try and use my existing 2 (1TB) drives + some new 2TB drives, and swap the 1TB ones out as I fill up. As to the actual questions: Should I use hardware RAID in some enclosure? Because if the enclosure dies I have to find an identical one to get to my data right? Wouldn't a software RAID be better as I can use any method of connecting the drives to the system? Remember OS X server is my OS. What if I had to reinstall OS X, can I restore the software RAID easily? What RAID version should I use? For the 2TB used for the time machine disk I don't see why I need RAID here, just a single 2TB drive since its already the backup, but for the remaining 4TB it would be the only copy of the data so I should build some redundancy. I had a RAID 5 setup using a cheep RAID PCI card years ago running RAID 5 in a 2 TB array and when a drive died it wanted 48 hours to rebuild. Is this crazy slow for a setup of this size or is this to be expected? Any suggestions as to drive enclosures?

  • Why Does Private Access Remain Non-Private in .NET Within a Class?

    - by AMissico
    While cleaning some code today written by someone else, I changed the access modifier from Public to Private on a class variable/member/field. I expected a long list of compiler errors that I use to "refactor/rework/review" the code that used this variable. Imagine my surprise when I didn't get any errors. After reviewing, it turns out that another instance of the Class can access the private members of another instance declared within the Class. Totally unexcepted. Is this normal? I been coding in .NET since the beginning and never ran into this issue, nor read about it. I may have stumbled onto it before, but only "vaguely noticed" and move on. Can anyone explain this behavoir to me? Am I doing something wrong? I found this behavior in both C# and VB.NET. The code seems to take advantage of the ability to access private variables. Sincerely, Totally Confused Class Foo Private _int As Integer Private _foo As Foo Private _jack As Jack Private _fred As Fred Public Sub SetPrivate() _foo = New Foo _foo._int = 3 'TOTALLY UNEXPECTED _jack = New Jack '_jack._int = 3 'expected compile error because Foo doesn't know Jack _fred = New Fred '_fred._int = 3 'expected compile error because Fred hides from Foo End Sub Private Class Fred Private _int As Integer End Class End Class Class Jack Private _int As Integer End Class

  • Does clustered index on foreign key column increase join performance vs non-clustered ?

    - by alpav
    In many places it's recommended that clustered indexes are better utilized when used to select range of rows using BETWEEN statement. When I select joining by foreign key field in such a way that this clustered index is used, I guess, that clusterization should help too because range of rows is being selected even though they all have same clustered key value and BETWEEN is not used. Considering that I care only about that one select with join and nothing else, am I wrong with my guess ?

  • What CSS should I use to create a series of horizontal, non-wrapping blocks?

    - by JOhnC
    I have a set of dynamically generated content - anywhere between 1 and about 25 blocks (each of which I want to be about 250px wide. Clearly, this can run off-screen, but that's fine since my design allows for horizontal scrolling (using jQuery - I don't want the browser to do it with its own scroll bars). So what CSS - cross-browser - is the best approach? Floats seem to wrap unreliably, and the dynamic nature of the content which changes frequently through ajax calls - means that recalculating the container width is not very practical. Other CSS-based option?

  • What was the most refreshingly honest non-technical comment you saw?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored procedure, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

  • Are there programming languages that rely on non-latin alphabets?

    - by Jaxsun
    Every programming language I have ever seen has been based on the Latin alphabet, this is not surprising considering I live in Canada... But it only really makes sense that there would be programming languages based on other alphabets, or else bright computer scientists across the world would have to learn a new alphabet to go on in the field. I know for a fact that people in countries dominated by other alphabets develop languages based off the Latin alphabet (eg. Ruby from Japan), but just how common is it for programming languages to be based off of other alphabets like Arabic, or Cyrillic, or even writing systems which are not alphabetic but rather logographic in nature such as Japanese Kanji? Also are any of these languages in active widespread use, or are they mainly used as teaching tools? This is something that has bugged me since I started programming, and I have never run across someone who could think of a real answer.

  • Using nginx to rewrite urls inside outgoing responses

    - by Kev
    We have a customer with a site running on Apache. Recently the site has been seeing increased load and as a stop gap we want to shift all the static content on the site to a cookieless domains, e.g. http://static.thedomain.com. The application is not well understood. So to give the developers time to amend the code to point their links to the static content server (http://static.thedomain.com) I thought about proxying the site through nginx and rewriting the outgoing responses such that links to /images/... are rewritten as http://static.thedomain.com/images/.... So for example, in the response from Apache to nginx there is a blob of Headers + HTML. In the HTML returned from Apache we have <img> tags that look like: <img src="/images/someimage.png" /> I want to transform this to: <img src="http://static.thedomain.com/images/someimage.png" /> So that the browser upon receiving the HTML page then requests the images directly from the static content server. Is this possible with nginx (or HAProxy)? I have had a cursory glance through the docs but nothing jumped out at me except rewriting inbound urls.

  • Fluent nHibernate - How to map a non-key column on an association table?

    - by The Matt
    Taking an example that is provided on the Fluent nHibernate website, I need to extend it slightly: I need to add a 'Quantity' column to the StoreProduct table. How would I map this using nHibernate? An example mapping is provided for the given scenario above, but I'm not sure how I would get the Quantity column to map: public class StoreMap : ClassMap<Store> { public StoreMap() { Id(x => x.Id); Map(x => x.Name); HasMany(x => x.Employee) .Inverse() .Cascade.All(); HasManyToMany(x => x.Products) .Cascade.All() .Table("StoreProduct"); } }

  • How can I perform an idiomatic non-recursive flatten in ruby?

    - by nasmorn
    I have a method that returns an array of arrays. For convenience I use collect on a collection to gather them together. arr = collection.collect {|item| item.get_array_of_arrays} Now I would like to have a single array that contains all the arrays. Of course I can loop over the array and use the + operator to do that. newarr = [] arr.each {|item| newarr += item} But this is kind of ugly, is there a better way?

  • VMWare Pre-Allocated vs. Growable, which is faster?

    - by tekiegreg
    In an effort to increase speed in my Vmware setup, I was thinking about converting a Windows XP Guest 32 bit I have from growable to pre-allocated, I'm currently running VMWare Workstation 7 with Windows 7 64 bit as the host. Specs: Dual Core CPU, one allocated to guest 4GB of RAM, 2GB to guest HD max capacity is 500GB, 150GB allocated to guest (I have 300GB left and don't mind parting with the space, currently HD is 80GB and converting would obviously add another 70GB of space), HD that guest is running on is separate from Host OS Either that or any other suggestions you have might be appreciated, thanks!
