  • How bad is for SEO to "redirect" an user depending on his browser locale ?

    - by bgy
    For a personnal page I use the MultiViews options in Apache to determine which page he should see depending on his locale. Here is what I do. Options MultiViews AddLanguage fr .fr AddLanguage en .en <IfModule mod_negotiation.c> LanguagePriority fr en </IfModule> I am wondering if it is bad for SEO to do this since Googlebot will probably fall on 'fr' or 'en' but not both. Would it be fixed if I add a link inside my page to the different language page.

  • In a Linux user space process what is the address of the vsyscall page?

    - by TomMD
    I would like to acquire the address of the vsyscall page for my own uses. I only have two ideas here: alter the compiler to store this information in some known location after it is given to __start, or read /proc/[pid]/maps. I really don't want to read /proc/ as that is slow and shouldn't be necessary. I also don't want to make compiler modifications. Does anyone have an alternative? Is there a symbol I should know about? Its at the point I'm tempted to stuff this functionality into an ioctl call in a module I've developed as part of this work!

  • How do I set Silverlight to auto-update on OS X?

    - by jwhitlock
    Is there a way to have Silverlight automatically install updates without user interaction? I'm running Boxee on a Mac Mini, and I make heavy use of the Netflix app. However, when I start watching a Netflix movie or TV show, Silverlight often tells me "There is an update to Silverlight available, do you want to install it?" I have to start up Screen Sharing or plug in a mouse to click "OK" and continue. I'd rather just update Silverlight automatically without user interaction.

  • How do I get the output of an Xcode user script to auto indent?

    - by John Gallagher
    The Problem I want to press a key when I have a line highlighted and convert from a single line: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; to a multiline statement: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; What I've Tried I've got a simple ruby script that almost gets me there. #!/usr/bin/env ruby s = STDIN.read s.gsub!(/(:.+?\w) (\w.+?)/,'\1' + "\n\t" +'\2') print s When I set the output to "Replace Selection", I get this: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; When I set the output to "Place on Clipboard", then paste it in, I get the desired result: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; However, this is two keypresses which is clumsy. Any ideas how I can get the replaced text to obey Xcode's auto indent rules?

  • How do you map a composite id to a composite user type with Fluent NHibernate?

    - by gabe
    i'm working w/ a legacy database is set-up stupidly with an index composed of a char id column and two char columns which make up a date and time, respectively. I have created a icompositeusertype for the date and time columns to map to a single .NET DateTime property on my entity, which works by itself when not part of the id. i need to somehow use a composite id with key property mapping that includes my icompositeusertype for mapping to the two char date and time columns. Apparently w/ my version of Fluent NHibernate, CompositeIdentityPart doesn't have a CustomTypeIs() method, so i can't just do the following in my override: mapping.UseCompositeId() .WithKeyProperty(x => x.Id, CommonDatabaseFieldNames.Id) .WithKeyProperty(x => x.FileCreationDateTime) .CustomTypeIs<FileCreationDateTimeType>(); is something like this even possible w/ NHibernate let alone Fluent? I haven't been able to find anything on this.

  • Want to add a new property to a class, can I use anonymous functions for this?

    - by Blankman
    I have 2 Lists: List<User> List<UserStats> So I want to add a property Count to User (it doesn't have one now, and I can't change the implementation at this point). For a web service call, that returns json, I want to modify the User object. Basically I add the Users to a collection. So I want to add a modified user class (via anonymous functions?) to the collection before I serialize it to json. So something like: loop users { user.Count = userstats[user.ID].Count; list.Add(user); } is this possible? how?

  • How to find the process(es) which are hogging the machine

    - by Aaron Digulla
    Scenario: All of a sudden, my computer feels sluggish. Mouse moves but windows take ages to open, etc. uptime says the load is 7.69 and raising. What is the fastest way to find out which process(es) are the cause of the load? Now, "top" and similar tools isn't the answer because they either show CPU or memory usage but not both at the same time. What I need is the single command which I might be able to type as it happens - something that will figure out any of System is trying to swap 8GB of RAM to disk because process X ... or process X seeks all over the disk or process X uses 400% CPU" So what I'm looking for is iostat, htop/atop and similar tools run into one with an output like this: 1235 cp - Disk trashing 87 chrome - Uses 2&nbsp;GB of RAM 137 nfs_bench - Uses 95% of the network bandwidth I don't want a tool that gives me some numbers which I can analyze but a tool that tells me exactly which process causes the current load. Assume that the user in front of the keyboard barely knows how to write "process", but the user is quickly overwhelmed when it comes to "resident size", "virtual memory" or "process life cycle". My argument goes like this: A user notices a problem. There can be thousands of reasons ... well, almost :-) The user wants to know the source of the problem. The current solutions give me lots of numbers, and I need to know what these numbers mean. What I'm looking for is a meta tool. 99% of the data is irrelevant to the problem. So what the tool should do is look for processes which hog some resource and list only those along with "this process needs a lot of CPU, this produces many IRQs, this process allocates a lot of RAM (and it's still growing)". This will be a relatively short list. It will be much more simple for someone new to this to locate the culprit from this list than from the output of, say, htop which gives me about 5000 numbers but requires me to fold multi-threaded processes myself (I have 50 lines which say VIRT 2750M but only 16 GB of RAM - the machine ought to swap itself to death but of course, this is a misinterpretation of the data that can happen quickly).

  • Filtering out unique rows in MySQL

    - by jpatokal
    So I've got a large amount of SQL data that looks basically like this: user | src | dst 1 | 1 | 1 1 | 1 | 1 1 | 1 | 2 1 | 1 | 2 2 | 1 | 1 2 | 1 | 3 I want to filter out pairs of (src,dst) that are unique to one user (even if that user has duplicates), leaving behind only those pairs belonging to more than one user: user | src | dst 1 | 1 | 1 1 | 1 | 1 2 | 1 | 1 In other words, pair (1,2) is unique to user 1 and pair (1,3) to user 2, so they're dropped, leaving behind only all instances of pair (1,1). Any ideas? The answers to the question below can find the non-unique pairs, but my SQL-fu doesn't suffice to handle the complication of requiring that they belong to multiple users as well.

  • App Engine: how would you... snapshotting entities

    - by Andrew B.
    Let's say you have two kinds, Message and Contact, related by a db.ListProperty of keys on Message. A user creates a message, adds some contacts as recipients, and emails the message. Later, the user deletes one of the contact entities that was a recipient of the message. Our application should delete the appropriate Contact entity, but we want to preserve the original recipient list for the message that was sent for the user's records. In essence, we want a snapshot of the message entity at the time it was sent. If we naively delete the contact entity, though, we lose snapshot integrity; if not, we are left with an invalid key. How would you handle this situation, either in controller logic or model changes? class User(db.Model): email = db.EmailProperty(required=True) class Contact(db.Model): email = db.EmailProperty(required=True) user = db.ReferenceProperty(User, collection_name='contacts') class Message(db.Model): recipients = db.ListProperty(db.Key) # contacts sender = db.ReferenceProperty(User, collection_name='messages') body = db.TextProperty() is_emailed = db.BooleanProperty(default=False)

  • Page.Request behaviour

    - by StupidDeveloper
    I have a page and few controls. I'm doing a normal postback. On InitializeCulture event of the page the Page.Request object contains e.g. controls with their values - and that's great. But on the other hand, when I'm trying to access this collection on the Page_Load or OnInit events, it's way smaller and doesn't have any of the controls that have been there before. Can anyone tell me what happens with Page.Request between these events?

  • Need help building SQL Query (simple JOIN)

    - by Newbie
    Hello! In my database, I have a "users", a "quests" and a "questings" table. A user can solve a quest. Solving a quest will save the "user_id" and the "quest_id" in my "questings" table. Now, I want to select all quests, a user has NOT solved (meaning there is no entry for this user and quest in "questings" table)! Let's say the user has the id 14. How to write this query? After solving this query, I want to filter the results, too. A quest and a user has a city, too. What to do for writing a query which returns all quests, a user has NOT solved yet, in the users city (user city == quest city)?

    I am using Centos5 running on a VMWare but whenever I choose to open the User Manager menu from System-Administration, an error message always displays The user database cannot be read.

I am a Linux novice and have no idea how to fix this tiny issue. ANy help is thankful. Thank you.

  • Is the guideline: don't open email attachments or execute downloads or run plug-ins (Flash, Java) from untrusted sites enough to avert infection?

    - by therobyouknow
    I'd like to know if the following is enough to avert malware as I feel that the press and other advisory resources aren't always precisely clear on all the methods as to how PCs get infected. To my mind, the key step to getting infected is a conscious choice by the user to run an executable attachment from an email or download, but also viewing content that requires a plug-in (Flash, Java or something else). This conscious step breaks down into the following possibilities: don't open email attachments: certainly agree with this. But lets try to be clear: email comes in 2 parts -the text and the attachment. Just reading the email should not be risky, right? But opening (i.e. running) email attachments IS risky (malware can be present in the attachment) don't execute downloads (e.g. from sites linked from in suspect emails or otherwise): again certainly agree with this (malware can be present in the executable). Usually the user has to voluntary click to download, or at least click to run the executable. Question: has there ever been a case where a user has visited a site and a download has completed on its own and run on its own? don't run content requiring plug-ins: certainly agree: malware can be present in the executable. I vaguely recall cases with Flash but know of the Java-based vulnerabilities much better. Now, is the above enough? Note that I'm much more cautious than this. What I'm concerned about is that the media is not always very clear about how the malware infection occurs. They talk of "booby-trapped sites", "browser attacks" - HOW exactly? I'd presume the other threat would be malevolent use of Javascript to make an executable run on the user's machine. Would I be right and are there details I can read up on about this. Generally I like Javascript as a developer, please note. An accepted answer would fill in any holes I've missed here so we have a complete general view of what the threats are (even though the actual specific details of new threats vary, but the general vectors are known).
