• XP Client for NFS failure dialog on startup, but drive mapping works

  - by Matt Bennett

  I'm mounting an NFS share to some windows machines using the tools that come in the Services for UNIX Administration toolkit. I've set up the User Name Mapping service to use local passwd and group files. I had to manually start the User Name Mapping service, and then created an 'advanced map' from the XP machine's user to a uid that exists in on my NFS server, like so: Windows User: Matt Bennett UNIX Domain: PCNFS UNIX User: mattbennett UID: 10250 Primary: * I can map a network drive without any issues, and it correctly identifies the UID and GID to use, but when I reboot I get this message: "An error occurred while connecting to the NFS server. Make sure that the Client for NFS service has started. If the problem persists make sure Client for NFS service can communicate with User Name Mapping or PCNFS server." After dismissing the dialog, the machine finishes booting and the network drive is there in My Computer with the title "Disconnected Network Drive", but I can open it I can see the network share without a problem, and then it drops the 'disconnected' from its title. It seems like the services are starting in the wrong order or something, so the first attempt to connect fails but subsequent ones work as expected. There don't seem to be any symptoms apart from the dialog box, but obviously something's not quite right. What have I done wrong? Thanks, Matt.

• Apache Server Redirect Subdomain to Port

  - by Matt Clark

  I am trying to setup my server with a Minecraft server on a non-standard port with a subdomain redirect, which when navigated to by minecraft will go to its correct port, or if navigated to by a web browser will show a web-page. i.e.: **Minecraft** minecraft.example.com:25565 -> example.com:25465 **Web Browser** minecraft.example.com:80 -> Displays HTML Page I am attempting to do this by using the following VirtualHosts in Apache: Listen 25565 <VirtualHost *:80> ServerAdmin [email protected] ServerName minecraft.example.com DocumentRoot /var/www/example.com/minecraft <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/example.com/minecraft/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> <VirtualHost *:25565> ServerAdmin [email protected] ServerName minecraft.example.com ProxyPass / http://localhost:25465 retry=1 acquire=3000 timeout=6$ ProxyPassReverse / http://localhost:25465 </VirtualHost> Running this configuration when I browse to minecraft.example.com I am able to see the files in the /var/www/example.com/minecraft/ folder, however if I try and connect in minecraft I get an exception, and in the browser I get a page with the following information: minecraft.example.com:25565 -> Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /. Reason: Error reading from remote server Could anybody share some insight on what I may be doing wrong and what the best possible solution would be to fix this? Thanks.

• How come my Apache can't read my media folder, but it can load the site? (static files don't work)

  - by Alex

  Alias /media/ /home/matt/repos/hello/media <Directory /home/matt/repos/hello/media> Options -Indexes Order deny,allow Allow from all </Directory> WSGIScriptAlias / /home/matt/repos/hello/wsgi/django.wsgi /media is my directory. When I go to mydomain.com/media/, it says 403 Forbidden. And, the rest of my site doesn't work because all static files are 404s. Why? The page loads. Just not the media folder. Edit: hello is my project folder. I have tried 777 all my permissions of that folder.

• Craftsmanship Tour Day 1: Didit Long Island

  - by Liam McLennan

  On Monday I was at Didit for my first ever craftsmanship visit. Didit seem to occupy a good part of a non-descript building in Rockville Centre Long Island. Since I had arrived early from Seattle I had some time to kill, so I stopped at the Rockville Diner on the corner of N Park Ave and Sunrise Hwy. I thoroughly enjoyed the pancakes and the friendly service. After walking to the Didit office I met Rik Dryfoos, the Didit Engineering Manager who organised my visit, and got the introduction to Didit and the work they are doing. I spent the morning in the room shared by the Didit developers, who are working on some fascinating deep engineering problems. After lunch at a local Thai place I setup a webcam to record an interview with Rik and Matt Roman (Didit VP of Engineering). I had a lot of trouble with the webcam, including losing several minutes of conversation, but in the end I was very happy the result. Here are the full interviews with Rik and Matt: Interview with Rik Dryfoos Interview with Matt Roman We had a great chat, much of which is captured in the recording. It was such great conversation that I almost missed my train to Manhattan. I’m sure Didit will continue to do well with such a dedicated and enthusiastic team. I sincerely thank them for hosting me for the day. If you are looking for a true agile environment and the opportunity to work with a high quality team then you should talk to Didit.

• Stackify Gives Devs a Crack at the Production Server

  - by Matt Watson

  Originally published on SDTimes.com on 7/9/2012 by David Rubinstein.It was one of those interviews where you get finished talking about a company’s product, and you wonder aloud, “Well, THAT makes sense! Why hasn’t anyone thought of that before?” Matt Watson, CEO of Kansas City, Mo.-based startup Stackify, was telling me that the 10-person company is getting ready to launch its product in August (it’s in beta now) that will give developers an app-centric look into production servers so they can support and troubleshoot apps and fix bugs. Of course, this hasn’t happened in the past because of the security concerns of IT administrators, and a decided lack of expertise on the part of developers. Stackify installs on a server and acts like a proxy for developers, collecting data about the environment, discovering all the applications, scanning for config file changes, and doing server monitoring. “We become the central point that developers can see everything they need to know about their applications,” he said. “Developers can look at the files that are deployed, and query databases in a safe way.”  In his words:“The big thing we’re hoping is just giving them (developers) visibility. Most companies want to hire the junior developers that they pay $50,000 a year right out of college to do application support and troubleshooting and fix bugs, but those people don’t have access to production servers to troubleshoot. It becomes very difficult for them to do their job, so they end up spending all of their day bugging the senior developers, the managers or the system administrators to track down this stuff, which creates a huge bottleneck. And so what we can do is give that visibility to those lower-level people so that they can do this work and free up the higher-level people so they can be working on the next big thing.”Stackify itself might just prove to be the next big thing.

• samba + kerberos ssh single signon (SSO)

  - by Matt Delves

  Hey folks, I'm modifying an existing samba config that it works fine for authenticating AD users on linux servers to also handle Kerberos and SSO. I've successfully got pam_winbind to use kerberos and it is handing out tickets, as well as having configured SSH to allow GSSAPI and Kerberos. Unfortunately though, when attempting to login via PuTTY using SSO, it fails. Is anyone who is familiar with configuring this able to point me in the right direction? Thanks, Matt.

• Different files on shared partition?

  - by Matt Robertson

  I am dual-booting Windows 8 and Ubuntu 12.04. My partition scheme looks like this: /dev/sda1 - Windows 8 (nfts) /dev/sda2 - Ubuntu / (ext4) /dev/sda3 - Ubuntu home (ext4) /dev/sda5 - swap /dev/sda6 - Shared data partition (exfat) (First off, yes I do have exfat libraries installed on Ubuntu) I created some PNG images in Windows and saved them on my shared partition. From Ubuntu, I edited the images in GIMP and saved them (replacing the ones on the shared partition). When I boot into Windows, the files appear unchanged - exactly like they did before I edited them from Ubuntu. I even added a folder and deleted some other files, but none of these changes exist in Windows. When I boot into Ubuntu, all of the changes are still there. It is as if Windows is caching the old file structure... How is this possible? Thanks in advance.

• Come see us at JavaU at JavaOne!

  - by tmcginn

  In just a little under a month, JavaOne will be in full swing (no pun intended) and thousands of Java developers will gather to hear the latest Java news, immerse themselves in Java technology and learn some new things. This year, I am fortunate enough to be able to attend, along with my Java curriculum development colleagues Matt Heimer and Mike Williams. We start our week at JavaOne teaching a one-day session at JavaU on Sunday morning. If you have never attended a training session through JavaU, you should check it out. There are some terrific sessions this year, and it might help to justify your trip to JavaOne if you can say it was for training! This year I am teaching a one day session on Java SE 7 New Features - a great session for anyone interested in the specific details of what is new in Java SE 7. Matt is teaching a one-day session on Developing Portable Java EE applications with the Enterprise JavaBeans 3.1 API and Java Persistence 2.0 API  EJB, and Mike is doing a one-day session on developing Rich Client applications with Java SE 7 using Java FX 2. I asked Matt and Mike to tell me what developers can expect from their sessions. Matt: "My session will get you up to speed on everything you need to know to create portable Java EE 6 applications using EJB 3.1 and JPA 2. I am going to cover why everyone can benefit from using EJBs (and why developers should relearn them if they haven't looked at them for years). Students who attend my session will see JPA examples showcasing how to use relational databases in an enterprise applications without programming to JDBC and without writing SQL statements. EJB and JPA benefit from being paired together, so I will also show how transaction management is easier in a container. I encourage students to bring a laptop and code as they learn!" Mike: "My session covers how to develop a rich client application using Java FX 2. Starting with the basic concepts of JavaFX, students will see how a JavaFX application is built from its layout, to its controls, to its data structures. In addition, more advanced controls like charts, smart tables, and transitions will be added to the application. Finally, a quick review of JavaFX concurrency and data binding is included. Blended with the core concepts the session will include some of the latest JavaFX technology. This includes using Scene Builder to create a JavaFX UI and connecting your XML UI definition to Java code.  In addition, packaging of the JavaFX application will be covered with some examples of the new native packaging features." As I mentioned, my session covers the changes in the Java for SE 7, including the  language changes that were voted into Java SE 7 from Project Coin. I will also look at how you can take advantage if the the new I/O library (NIO.2) for writing applications that work with files, directories and file systems. We will also look at the changes in Asynchronous I/O that are a part of the changes in NIO/2. We will spend some time looking at the changes to the Java Virtual Machine as well, including support for dynamically typed languages (JSR-292). We will spend some time looking at the Java Concurrency enhancements (JSR-166), including the new Fork/Join framework. And we'll round out the day with a look at changes in Swing, XML and a number of smaller changes in the API's. And, if these topics aren't grabbing your interest, take a look at the other 10 sessions that range from topics on architecture to how to pass the Oracle Certified Programmer I and II exams. See you soon!

• Stackify Aims to Put More ‘Dev’ in ‘DevOps’

  - by Matt Watson

  Originally published on VisualStudioMagazine.com on 8/22/2012 by Keith Ward.The Kansas City-based startup wants to make it easier for developers to examine the network stack and find problems in code.The first part of “DevOps” is “Dev”. But according to Matt Watson, Devs aren’t connected enough with Ops, and it’s time that changed.He founded the startup company Stackify earlier this year to do something about it. Stackify gives developers unprecedented access to the IT side of the equation, Watson says, without putting additional burden on the system and network administrators who ultimately ensure the health of the environment.“We need a product designed for developers, with the goal of getting them more involved in operations and app support. Now, there’s next to nothing designed for developers,” Watson says. Stackify allows developers to search the network stack to troubleshoot problems in their software that might otherwise take days of coordination between development and IT teams to solve.Stackify allows developers to search log files, configuration files, databases and other infrastructure to locate errors. A key to this is that the developers are normally granted read-only access, soothing admin fears that developers will upload bad code to their servers.Implementation starts with data collection on the servers. Among the information gleaned is application discovery, server monitoring, file access, and other data collection, according to Stackify’s Web site. Watson confirmed that Stackify works seamlessly with virtualized environments as well.Although the data collection software must be installed on Windows servers, it can monitor both Windows and Linux servers. Once collection’s finished, developers have the kind of information they need, without causing heartburn for the IT staff.Stackify is a 100 percent cloud-based service. The company uses Windows Azure for hosting, a decision Watson’s happy with. With Azure, he says, “It’s nice to have all the dev tools like cache and table storage.” Although there have been a few glitches here and there with the service, it’s run very smoothly for the most part, he adds.Stackify is currently in a closed beta, with a public release scheduled for October. Watson says that pricing is expected to be $25 per month, per server, with volume discounts available. He adds that the target audience is companies with at least five developers.Watson founded Stackify after selling his last company, VinSolutions, to AutoTrader.com for “close to $150 million”, according to press accounts. Watson has since  founded the Watson Technology Group, which focuses on angel investing.About the Author: Keith Ward is the editor in chief of Visual Studio Magazine.

• Kauffman Foundation Selects Stackify to Present at Startup@Kauffman Demo Day

  - by Matt Watson

  Stackify will join fellow Kansas City startups to kick off Global Entrepreneurship WeekOn Monday, November 12, Stackify, a provider of tools that improve developers’ ability to support, manage and monitor their enterprise applications, will pitch its technology at the Startup@Kauffman Demo Day in Kansas City, Mo. Hosted by the Ewing Marion Kauffman Foundation, the event will mark the start of Global Entrepreneurship Week, the world’s largest celebration of innovators and job creators who launch startups.Stackify was selected through a competitive process for a six-minute opportunity to pitch its new technology to investors at Demo Day. In his pitch, Stackify’s founder, Matt Watson, will discuss the current challenges DevOps teams face and reveal how Stackify is reinventing the way software developers provide application support.In October, Stackify had successful appearances at two similar startup events. At Tech Cocktail’s Kansas City Mixer, the company was named “Hottest Kansas City Startup,” and it won free hosting service after pitching its solution at St. Louis, Mo.’s Startup Connection.“With less than a month until our public launch, events like Demo Day are giving Stackify the support and positioning we need to change the development community,” said Watson. “As a serial technology entrepreneur, I appreciate the Kauffman Foundation’s support of startup companies like Stackify. We’re thrilled to participate in Demo Day and Global Entrepreneurship Week activities.”Scheduled to publicly launch in early December 2012, Stackify’s platform gives developers insights into their production applications, servers and databases. Stackify finally provides agile developers safe and secure remote access to look at log files, config files, server health and databases. This solution removes the bottleneck from managers and system administrators who, until now, are the only team members with access. Essentially, Stackify enables development teams to spend less time fixing bugs and more time creating products.Currently in beta, Stackify has already been named a “Company to Watch” by Software Development Times, which called the startup “the next big thing.” Developers can register for a free Stackify account on Stackify.com.###Stackify Founded in 2012, Stackify is a Kansas City-based software service provider that helps development teams troubleshoot application problems. Currently in beta, Stackify will be publicly available in December 2012, when agile developers will finally be able to provide agile support. The startup has already been recognized by Tech Cocktail as “Hottest Kansas City Startup” and was named a “Company to Watch” by Software Development Times.

• Session Cookies and IE 8

  - by Matt Luongo

  I recently built a simple web-app deployed over Tomcat. The app uses pretty standard session based security where a user who has logged in is given a session. Sessions work fine in Firefox and Chrome, but require the use of jsessionid in the URL for IE (tested 7 & 8), set to medium privacy. In IE 8, I tried to override cookie handling, setting "Allow all 3rd party cookies" and "Allow all session cookies"- no dice.

I thought it might be P3P, but on adding a compact policy, nothing changes.

• Convert Javascript Regular Expression to PHP (PCRE) Expression

  - by Matt

  Hi all, I am up to my neck in regular expressions, and I have this regular expression that works in javascript (and flash) that I just can't get working in PHP Here it is: var number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; var oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]' + '|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; var str = '(?:\"' + oneChar + '*\")'; var varName = '\\$(?:' + oneChar + '[^ ,]*)'; var func = '(?:{[ ]*' + oneChar + '[^ ]*)'; // Will match a value in a well-formed JSON file. // If the input is not well-formed, may match strangely, but not in an unsafe // way. // Since this only matches value tokens, it does not match whitespace, colons, // or commas. var jsonToken = new RegExp( '(?:false|true|null' +'|[\\}]' + '|' + varName + '|' + func + '|' + number + '|' + str + ')', 'g'); If you want it fully assembled here it is: /(?:false|true|null|[\}]|\$(?:(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ,]*)|(?:{[ ]*(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ]*)|(?:-?\b(?:0|[1-9][0-9]*)(?:\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\b)|(?:"(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))*"))/g Interestingly enough, its very similar to JSON. I need this regular expression to work in PHP... Here's what I have in PHP: $number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; $oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; $string = '(?:\"'.$oneChar.'*\")'; $varName = '\\$(?:'.$oneChar.'[^ ,]*)'; $func = '(?:{[ ]*'.$oneChar.'[^ ]*)'; $jsonToken = '(?:false|true|null' .'|[\\}]' .'|'.$varName .'|'.$func .'|'.$number .'|'.$string .')'; echo $jsonToken; preg_match_all($jsonToken, $content, $out); return $out; Here's what happens if I try using preg_match_all(): Warning: preg_match_all() [function.preg-match-all]: Compilation failed: nothing to repeat at offset 0 in /Users/Matt/Sites/Templating/json/Jeeves.php on line 88 Any help would be much appreciated! Thanks, Matt

• Python "Every Other Element" Idiom

  - by Matt Luongo

  Hey guys, I feel like I spend a lot of time writing code in Python, but not enough time creating Pythonic code. Recently I ran into a funny little problem that I thought might have an easy, idiomatic solution. Paraphrasing the original, I needed to collect every sequential pair in a list. For example, given the list [1,2,3,4,5,6], I wanted to compute [(1,2),(3,4),(5,6)]. I came up with a quick solution at the time that looked like translated Java. Revisiting the question, the best I could do was l = [1,2,3,4,5,6] [(l[2*x],l[2*x+1]) for x in range(len(l)/2)] which has the side effect of tossing out the last number in the case that the length isn't even. Is there a more idiomatic approach that I'm missing, or is this the best I'm going to get?

• Big Nerd Ranch's Android Bootcamp - worth it?

  - by Matt Luongo

  At work, I've been told that I must, before the end of the year, get a certification. The shop is Microsoft heavy, and I'm not. That's why I was excited when I suggested something in support of Android development, and they agreed. Before I go any further, I should say that I don't know what I think about the whole certification question. Frankly, though, I need to do this, regardless of whether I think certification in general is particularly appealing to clients. I realize that the technology is fairly accessible without all this expensive process- but I'd rather focus on Android than, say, getting some MC* scrap of paper. I don't know of any actual Android certification. Instead, I was thinking that the best regarded Android training in the industry should suffice. I've looked into Big Nerd Ranch's Android Bootcamp, and it looks promising. I live in Atlanta, which is a boon. Given that my Java skills are good, does this seem like a decent course? Or is there a better known training program that I should look into?

• Does Python's shelve module use memory-mapped IO?

  - by Matt Luongo

  Does anyone know if Python's shelve module uses memory-mapped IO? Maybe that question is a bit misleading. I realize that shelve uses an underlying dbm-style module to do its dirty work. What are the chances that the underlying module uses mmap? I'm prototyping a datastore, and while I realize premature optimization is generally frowned upon, this could really help me understand the trade-offs involved in my design.

• Overlapping matches with finditer() in Python

  - by Raphink

  Hi there, I'm using a regex to match Bible verse references in a text. The current regex is REF_REGEX = re.compile(r'(?<!\w)((?i)q(?:uote)?\s+)?((?:(?:[1-3]|I{1,3})\s*)?[A-Za-z]+)\.?(?:\s*(\d+)(?:[:.](\d+)(?:-(\d+))?)?)(?:\s+(?:(?i)(?:from\s+)|(?:in\s+)|(?P<lbrace>\())\s*(\w+)(?(lbrace)\)))?', re.UNICODE) This matches the following expressions fine: "jn 3:16": (None, 'jn', '3', '16', None, None, None), "matt. 18:21-22": (None, 'matt', '18', '21', '22', None, None), "q matt. 18:21-22": ('q ', 'matt', '18', '21', '22', None, None), "QuOTe jn 3:16": ('QuOTe ', 'jn', '3', '16', None, None, None), "q 1co13:1": ('q ', '1co', '13', '1', None, None, None), "q 1 co 13:1": ('q ', '1 co', '13', '1', None, None, None), "quote 1 co 13:1": ('quote ', '1 co', '13', '1', None, None, None), "quote 1co13:1": ('quote ', '1co', '13', '1', None, None, None), "jean 3:18 (PDV)": (None, 'jean', '3', '18', None, '(', 'PDV'), "quote malachie 1.1-2 fRom Colombe": ('quote ', 'malachie', '1', '1', '2', None, 'Colombe'), "quote malachie 1.1-2 In Colombe": ('quote ', 'malachie', '1', '1', '2', None, 'Colombe'), "cinq jn 3:16 (test)": (None, 'jn', '3', '16', None, '(', 'test'), "Q IIKings5.13-58 from wolof": ('Q ', 'IIKings', '5', '13', '58', None, 'wolof'), "This text is about lv5.4-6 in KJV only": (None, 'lv', '5', '4', '6', None, 'KJV'), but it fails to parse: "Found in 2 Cor. 5:18-21 ( Ministers": (None, '2 Cor', '5', '18', '21', None, None), because it returns (None, 'in', '2', None, None, None, None) instead. Is there a way to get finditer() to return all matches, even if they overlap, or is there a way to improve my regex so it matches this last bit properly? Thanks.

• Learning web development as I go

  - by Matt Luongo

  Hey everybody, I've been seriously preparing to take the entrepreneurship leap. I've got a great partner, and we're going to take on some minor funding, and do the thing. Our product is web-based- I'll deem it YAWA (Yet Another Web Application). Both my partner and I have database and web development experience, and I've had a front-end developer in mind for a while. Except, well- he just bowed out. I know a fair amount about the associated technologies (XHTML, CSS, Javascript and some JQuery) interface-side, but I've never had to deal with real-world scenarios, eg cross-browser design. Am I going to be able to survive without this guy? Is it realistic to believe that I can learn the details as I go?
