Google Bot trying to access my web app's sitemap

- by geekrutherford

Interesting find today... I was perusing the event log on our web server today for any unexpected ASP.NET exceptions/errors. Found the following: Exception information: Exception type: HttpException Exception message: Path '/builder/builder.sitemap' is forbidden. Request information: Request URL: https://www.bondwave.com:443/builder/builder.sitemap Request path: /builder/builder.sitemap User host address: 66.249.71.247 User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE At first I thought this was maybe an attempt by a hacker to mess with the sitemap. Using a handy web site (www.network-tools.com) I did a lookup on the IP address and found it was a Google bot trying to crawl the application. In this case, I would expect an exception or 403 since the site requires authentication anyway.

How does one handle sensitive data when using Github and Heroku?

- by Jonas

I am not yet accustomed with the way Git works (And wonder if someone besides Linus is ;)). If you use Heroku to host you application, you need to have your code checked in a Git repo. If you work on an open-source project, you are more likely going to share this repo on Github or other Git hosts. Some things should not be checked in the public repo; database passwords, API keys, certificates, etc... But these things still need to be part of the Git repo since you use it to push your code to Heroku. How to work with this use case? Note: I know that Heroku or PHPFog can use server variables to circumvent this problem. My question is more about how to "hide" parts of the code.

Le W3C présente Web cryptography API, une norme pour améliorer la sécurité des applications Web

Le W3C présente Web cryptography API une norme pour améliorer la sécurité des applications Web La sécurité est un aspect important dans le cycle de développement d'une application. Les développeurs ont souvent recours à des outils tiers ou doivent développer au prix de nombreux efforts leurs propres fonctionnalités de cryptographie. Le W3C (World Wide Web Consortium), l'organisme de normalisation des standards du Web ouvert, travaille actuellement sur un standard qui vise à améliorer la sécurité des applications Web tout en facilitant la tâche du développeur. L'organisme vient de publier un premier brouillon (draft) pour l'API Web cryptography. Le projet a...

Internal and external API architecture

- by Tacomanator

The company I work for maintains a successful SaaS product that grew "organically" over the years. We are planning to expand the line with a suite of new products that will share data with the existing product. To support this, we are looking to consolidate business logic into a single place: a web service layer. The WS layer will be used by: The web applications A tool to import data A tool to integrate with other client software (not an API per se) We also want to create an API that can be used by our customers that are capable of using it to create their own integrations. We are struggling with the following question: Should the internal API (aka the WS layer) and the external API be one in the same, with security and permission settings to control what can be done by who, or should they be two separate applications where the external API just calls the internal API like any other application? So far in our debate it seems that separating them may be more secure, but will add overhead. What have others done in a similar situation?

How to find corrupted files?

- by rafalcieslak

Some files on my hard drive are corrupted (no worries, nothing system-related, just a junk of data files, mp3 etc.). I found that out when I tried to burn them all to a DVD, the burning application show a message that it cannot read the files as they are corrupted. [This is probably a drive issue, it had happened me once or twice already]. I don't care about recovering them, but I have to determine which ones are corrupted. I cannot check by manually opening them all, as there are thousands of them. Is there any tricky way to check all the files and list the ones that may cause problems when tried to open?

Real performance of node.js

- by uther.lightbringer

I've got a question concerning node.js performance. There is quite lot of "benchmarks" and a lot of fuss about great performance of node.js. But how does it stand in real world? Not just process empty request at high speed. If someone could try to compare this scenario: Java (or equivalent) server running an application with complex business logic between receiving request and sending response. How would node.js deal with it? If there was need for a lot of JavaScript processing on server side, is node.js really so fast that it can execute JavaScript, and stand a chance against more heavyveight competitors?

adding executable file to path and launching from terminal directly

- by ubunnttuu

i just downloaded sublime text for my ubuntu, and its working fine. i have the executable file in my ~/sublime folder. now i would like to invoke this app from the terminal by just typing sublime. i suppose that is possible, pls let me know how. also, since this application did not need any configure/make/install (i just had to extract it and then use the exec file to run the app), i cannot add this to my gnome launcher fav apps panel. how can i put the app shortcut there, so that when i do a top-left and then type sublime, the results will show the applicaion and then i can click on it and invoke the app from there? thanks!

Bug Tracking Etiquette - Necromancy or Duplicate?

- by Shauna

I came across a really old (2+ years) feature request issue in a bug tracker for an open source project that was marked as "resolved (won't fix)" due to the lack of tools required to make the requested enhancement. In the time elapsed since that determination was made, new tools have been developed that would allow it to be resolved, and I'd like to bring that to the attention of the community for that application. However, I'm not sure as to what the generally accepted etiquette is for bug tracking in cases like this. Obviously, if the system explicitly states to not duplicate and will actively mark new items as duplicates (much in the way the SE sites do), then the answer would be to follow what the system says. But what about when the system doesn't explicitly say that, or a new user can't easily find a place that says with the system's preference is? Is it generally considered better to err on the side of duplication or necromancy? Does this differ depending on whether it's a bug or a feature request?

How do you navigate and refactor code written in a dynamic language?

- by Philippe Beaudoin

I love that writing Python, Ruby or Javascript requires so little boilerplate. I love simple functional constructs. I love the clean and simple syntax. However, there are three things I'm really bad at when developing a large software in a dynamic language: Navigating the code Identifying the interfaces of the objects I'm using Refactoring efficiently I have been trying simple editors (i.e. Vim) as well as IDE (Eclipse + PyDev) but in both cases I feel like I have to commit a lot more to memory and/or to constantly "grep" and read through the code to identify the interfaces. As for refactoring, for example changing method names, it becomes hugely dependent on the quality of my unit tests. And if I try to isolate my unit tests by "cutting them off" the rest of the application, then there is no guarantee that my stub's interface stays up to date with the object I'm stubbing. I'm sure there are workarounds for these problems. How do you work efficiently in Python, Ruby or Javascript?

How to get MAC address from c# [migrated]

- by Andrew Simpson

I have a C# application. In a routine I have code to get the MAC address from using SendARP. It works on Windows 7 but does not work on Windows XP. I just get a null string returned. This is my code. Thanks... System.Runtime.InteropServices.DllImport("iphlpapi.dll", ExactSpelling = true)] static extern int SendARP(int DestIP, int SrcIP, byte[] pMacAddr, ref int PhyAddrLen); public static PhysicalAddress GetMacAddress(IPAddress ipAddress) { const int MacAddressLength = 6; //i know it is has a length of 6 int length = MacAddressLength; var macBytes = new byte[MacAddressLength]; SendARP(BitConverter.ToInt32(ipAddress.GetAddressBytes(), 0), 0, macBytes, ref length); return new PhysicalAddress(macBytes); }

What are my options for selling software independently on Windows?

- by technomalogical

I am looking to port a tool from the Mac app store over to Windows, the platform where I spend most of my time these days. I've spoken with the author of the original app and we've begun talking about licensing options should I decide to sell the application, and it seems like it would be feasible. I've never sold software independently, let alone on Windows. That I know of, there is not (yet) an equivalent app store for Windows (maybe one coming with Windows 8). Assuming my product was done today and I was ready to go to market, what options do I have for selling software for Windows as an independent developer or Micro-ISV? I know can sell it through my own website and accept PayPal, but are there options that will offer more visibility, similar to that of the Apple app stores? Any options to avoid?

Ubuntu boots to black screen after failed upgrade from 12.04 to 12.10

- by ywx

This happened when I tried to upgrade from 12.04 to 12.10. I don't know whether the upgrade process had completed downloading and installing packages or whether it was still in progress, but I got a message The application Compiz has closed unexpectedly. At that point, my mouse stopped working so I switched to tty1 by Ctrl+Alt+F1 and rebooted from there. I then found that I could not boot into Ubuntu any more. My screen stayed first purple then black. I went back to tty1 and it said I was running 12.10. I tried some suggestions in this thread on Ubuntuforums: Wubi blank purple screen than blank black screen and this one: How to set NOMODESET and other kernel boot options in grub2 but nothing seemed to work. I can boot Windows as normal. I am using Wubi on Windows7. My laptop is a Lenovo T410i with NVIDA NVS 3100m

Google crawler not found an error inside of the <head> tag

- by inckka

I've found a crawler error in my site and it is listed as a page not found(404) link. Heres the broken link http://mydomain.com/blog/comments/feed/ I'm using Google web master tools and found that broken link coming from my web site pages' head tag. here's actual code where that link situated. <head> <link rel="alternate" type="application/rss+xml" title="My Domain Blog » Feed" href="http://www.my-domain.com/blog/feed/" /> </head> So Google report this link as a not found. Actually this link target is not an exact page or a location. But essential for the blog feeds. Anyway I have to fix this and remove from the Google crawler error's list. But haven't got any idea, because cannot redirect or do a 404 header with this link target. Have anyone got an idea of fixing this?

Nokia tente le développement sans développeur pour relancer sa galerie mobile : est-ce vraiment un b

Nokia lance le développement sans développeur Pour relancer sa galerie mobile : mais est-ce vraiment un bon pari à faire ? Nokia tente de relancer sa galerie d'applications mobiles. Il est vrai que les professionels ne semblent pas particulièrement attirés par l'OviStore. Pour preuve, ses 6.800 applications (chiffre Distimo) font bien pâle figure face aux presque 50.000 de l'Android Market de Google, et aux quasiment 200.000 de l'AppStore d'Apple. Qu'à cela ne tienne, puisque les développeurs ne lui font pas d'applications, Nokia vient de créer une application pour faire des développeurs. La formule est caricaturale. Mais elle résume bien la volonté du constr...

How to run applications as root?

- by ????? ????????

I am having some strange issue with Kate and Kwrite. When I click on Open File, it crashes with segmentation fault. I am a complete newbie to Linux, and I think the issue is that I am not running the application as root. How do I run applications as root in Ubuntu? Is it bad practice to do this? What is the purpose of the whole root thing, where even though we need to use root so frequently, it is not utilized as default?

Low complexity shader to indicate the sides of a polyline

- by Pris

I have a bunch of polylines that I draw using GL_LINES. They can have thousands of points. They actually represent the separation of land and water on a map. I don't have complete polygons, just the ordered set of points. I'm looking for a neat but efficient way to visually convey Side A and Side B as being different. For example I could offset the polyline in one direction a few times and fade it out (but every offset is doubling the number of points), or offset it once to make a "ribbon" and give one side a 'glow' like effect to mimic the outer glow or shadow of a polygon). This is for a mobile application and I'm using OpenGL ES 2. I'd like to keep the effect as simple as possible from a complexity stand point. I'm looking for some additional ideas; maybe there's a clever shader technique out there or a visual effect I haven't considered.

What's the difference between MCSD and MCPD?

- by Damien

I am looking on the website but the difference between the two isn't explained. To complicate matters a Google search tells me that developers should focus on the MCPD qualifications but an examination of the MCPD section of the site is telling me that the Web Application exams will expire in July 2013! It seems out of date. Meanwhile the MCSD exam seems to be a lot more up to date with references to HTML5/ASP.net 4.5 MVC applications! What's the difference. Are the MCPD going to be updated after July? Thanks

Q&A: Does it make sense to run a personal blog on the Windows Azure Platform?

- by Eric Nelson

I keep seeing people wanting to do this (or something very similar) and then being surprised at how much it might cost them if they went with Windows Azure. Time for a Q&A. Short answer: No, definitely not. Madness, sheer madness. (Hopefully that was clear enough) Longer answer: No because It would cost you a heck of a lot more than just about any other approach to running a blog. A site that can easily be run on a shared hosting solution (as many blogs do today) does not require the rich capabilities of Windows Azure. Capabilities such as simplified deployed and management, dedicated resources, elastic resources, “unlimited” storage etc. It is simply not the type of application the Windows Azure Platform has been designed for. Related Links: Q&A- How can I calculate the TCO and ROI when considering the Windows Azure Platform? Q&A- When do I get charged for compute hours on Windows Azure?

Ubuntu One messes up with my thunderbird folders

- by xpanta

I have added .thunderbird folder to my Ubuntu One's folders to be synced. This is to protect my mails and my thunderbird's settings and plugins. However, U1 constantly keeps messing up with my folders and a lot of .u1conflict files appear in various places in my .thunderbird folder. Some of them I see on my thunderbird application when I start it up. Why is that? Can't I just select my home folders files to be uploaded and not synced? Or set U1, in case of conflicts, to leave the home folder structure and files as is. PS: I have subscribed to U1 service and this is important to me.

Is nesting types considered bad practice?

- by Rob Z

As noted by the title, is nesting types (e.g. enumerated types or structures in a class) considered bad practice or not? When you run Code Analysis in Visual Studio it returns the following message which implies it is: Warning 34 CA1034 : Microsoft.Design : Do not nest type 'ClassName.StructueName'. Alternatively, change its accessibility so that it is not externally visible. However, when I follow the recommendation of the Code Analysis I find that there tend to be a lot of structures and enumerated types floating around in the application that might only apply to a single class or would only be used with that class. As such, would it be appropriate to nest the type sin that case, or is there a better way of doing it?

statistics for checking imported data?

- by user1936

I'm working on a data migration of several hundred nodes from a Drupal 6 to a Drupal 7 site. I've got the data exported to the new site and I want to check it. Harkening back to my statistics classes, I recall that there is some way to figure out a random number of nodes to check to give me some percentage of confidence that the whole process was correct. Can anyone enlighten me as to this practical application of statistics? For any given number of units, how big must the sample be to have a given confidence interval?
