• Win 7 Explorer backup and long paths

  - by user53299

  I use Explorer to do backups because Win 7's backup program asks me to take backups previously done and to put them back in the drive. I am opposed to that idea since I believe backups should remain in storage. With Explorer backups (burn and burn to disc) I have encountered the "destination path too long" error message and it shows the name of a folder "Debug" three times. I have hundreds of folders named "Debug" thanks to Visual Studio. At this moment I'm too angry at Microsoft to write a program to determine my 3 longest paths. (Aside: This is all after coincidentally reading two articles about path junctions earlier this evening which already made me kind of unhappy.) Please, is there an easy way to continue to make backups with Explorer? Edit: I should add that renaming paths wrecks Visual Studio projects so I really need to isolate the small number of problem paths or find a cleaner solution.

• SSL certs or intermediate for DMZ

  - by rex

  I've been tasked with deploying and managing load balancers covering internal servers and DMZ servers. I have no experience with this, and this is a first for my organization as well. Balancers are up, running, legit. Currently we are using a self-signed cert for Exchange/OWA. I know that we should have a cert signed by a CA, but the balancer has options for SSL cert or intermediate cert, and I'm unclear on the difference, or on which we need. We will be hosting Lync, Exchange and some custom apps in the DMZ. disclaimer: Apologies up front, I'm desktop support. I recently passed my Net+. It seems that has made me the network engineer in this organization.

• MSDN Live 2010 &ndash; Delivered : 24 sessions (4 x 6) on Visual Studio and Team Foundation Server

  - by terje

  We (Mikael Nitell and me) got a whole track on the Norwegian MSDN Live tour this year.  We did these as a pair, and covered 4 cities over 4 days, 6 sessions per day, taking 8 hours to come through it.  The Islandic volcano made the travels a bit rough, but we managed 6 flights out of 8. The first one had to go by van instead, 7-8 hour drive each way together with other MSDN Live presenters – a memorable tour! Oslo was the absolute top point.  We had to change hall to a bigger one. People were crowding, and even the big hall was packed!  The presentations were mostly based on demos, but we had a few slides as well.  They have been uploaded to my SkyDrive.  Info to aliens – some of the text may be Norwegian. The sessions were as follows: Overview of news in Visual Studio and Team Foundation server 2010 Ensuring Quality with VS/TFS 2010 Releasing products with VS/TFS 2010 No More No Repro with VS/TFS 2010 Performance Testing and Parallel Programming with VS/TFS 2010 Migrating to VS/TFS 2010 Tips, tricks, news and some best practices with VS/TFS 2010   In the coming days, I will post up examples from the demos too, with explanations of how they are intended to work. These entries will also contain stuff we had to remove from the actual presentations due to the time constraints. We managed to create recordings of two of the sessions, which will be uploaded to Channel 9 by Microsoft, afaik.   I will update this blog with information about exact locations when that is done. Also note we’re (read:Osiris Data AS) running both Upgrade and Deep Dive courses  on VS/TFS 2010 now in May.  Please look here for more info. If you want to be informed, follow me on Twitter.  All blog entries will be announced on twitter.

• What are my choices for server side sandboxed scripting?

  - by alfa64

  I'm building a public website where users share data and scripts to run over some data. The scripts are run serverside in some sort of sandbox without other interaction this cycle: my Perl program reads from a database a User made script, adds the data to be processed into the script ( ie: a JSON document) then calls the interpreter, it returns the response( a JSON document or plain text), i save it to the database with my perl script. The script should be able to have some access to built in functions added to the scripting language by myself, but nothing more. So i've stumbled upon node.js as a javascript interpreter, and and hour or so ago with Google's V8(does v8 makes sense for this kind of thing?). CoffeeScript also came to my mind, since it looks nice and it's still Javascript. I think javascript is widespread enough and more "sandboxeable" since it doesn't have OS calls or anything remotely insecure ( i think ). by the way, i'm writing the system on Perl and Php for the front end. To improve the question: I'm choosing Javascript because i think is secure and simple enough to implement with node.js, but what other alternatives are for achieving this kind of task? Lua? Python? I just can't find information on how to run a sandboxed interpreter in a proper way.

• What kind of language will replace C++ as C++ replaced C ? [closed]

  - by jokoon

  I think I'm not totally wrong when thinking that C++0x (or C++1x) is still C++, just better, with functionnalities coming from boost. I can't stop thinking that computer sciences, even with all that has been made so far, have to evolve again. I don't really like D since it just try to be some sort of "what C++ should have been", and Go seems to be too sophisticated when I dig a little into it, especially after watching some presentation video like this one http://www.youtube.com/watch?v=rKnDgT73v8s The first thing that come into my mind is a new kind of syntax to directly handle specific datatypes and containers such as map, vectors, queues... What kind of things are researchers thinking about ? What are the real features that could make C++ better or a new C-like language could invent ? Does Go features such things ? Would there be a new kind of syntax that would "unbloat" C++ while keeping its advantages ? Could C++ have some of the interesting stuff of languages such as C# and ObjC ? EDIT: Please consider that I'm talking about a system language, not a VM/CLI/bytecode thing.

• Html 5 clock, part ii - CSS marker classes and getElementsByClassName

  - by Norgean

  The clock I made in part i displays the time in "long" - "It's a quarter to ten" (but in Norwegian). To save space, some letters are shared, "sevenineight" is four letters shorter than "seven nine eight". We only want to highlight the "correct" parts of this, for example "sevenineight". When I started programming the clock, each letter had its own unique ID, and my script would "get" each element individually, and highlight / hide each element according to some obscure logic. I quickly realized, despite being in a post surgery haze, …this is a stupid way to do it. And, to paraphrase NPH, if you find yourself doing something stupid, stop, and be awesome instead. We want an easy way to get all the items we want to highlight. Perhaps we can use the new getElementsByClassName function? Try to mark each element with a classname or two. So in "sevenineight": 's' is marked as 'h7', and the first 'n' is marked with both 'h7' and 'h9' (h for hour). <div class='h7 h9'>N</div><div class='h9'>I</div> getElementsByClassName('h9') will return the four letters of "nine". Notice that these classes are not backed by any CSS, they only appear directly in html (and are used in javascript). I have not seen classes used this way elsewhere, and have chosen to call them "marker classes" - similar to marker interfaces - until somebody comes up with a better name.

• Account Listings on APress and O'Reilly

  - by TATWORTH

  Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2013/06/20/e-books-from-apress-and-oreilly.aspxIn recent days both APress and O'Reilly have radically improved the way they display items registered against your account with them.APress now show only one line per e-book and the multitude of formats is handled by a drop-down list. The result is that the list of APress books I have bought now requires less paging through. The only things that the APress lacks are:The ability to show all on the page (currently options for 10,20 and 50 per page)The ability to sort on title or date bought or date updatedO'Reilly have always shown the formats available by a series of hyperlinks along one line. They have improved their list as follows:You can sort on title or date bought or date updatedClicking on a line shows full detail of the item (include image, download details, errata link and catalog page). Clicking again collapses the detail.You can select all your purchased items together or just show E-Books or Print or VideosNow why is the date updated important? Updates are issued for various books  (particularly those made available whilst still being written) - the publishers very kindly email you when an update is available but finding it in the list to download it again is not as easy as you think, however sort on release date and they are easy to find!

• How do you keep SOA DRY?

  - by TaylorOtwell

  In our organization, we've shifted to a more "service oriented architecture". To give an example, let's assume we need to retrieve a "Quote" object. This quote has a shipper, a consignee, phone numbers, contacts, email addresses, and other location information. In other words, a Quote object is made up of many other objects. So, it seems like it would make sense to make a "Quote Retrieval Service". In our situation, we've accomplished this by creating a .NET solution and writing the service. The service API looks something like this (in pseudo-code): Function GetQuote(String ID) Returns Quote So, so far so good. Now, when this service is consumed, to keep things "de-coupled", we are creating essentially a duplicate of the Quote object and mapping from the QuoteService version of the Quote into the consumer's version of the Quote. In many cases, these classes will have the exact same properties. So, if the Quote service is consumed by 5 other applications, we would have 6 definitions of what a "Quote" is. One for each consumer, and one for the service. This feels wrong. I thought code was supposed to be DRY, but it seems like our method of SOA is forcing us to create tons of duplicated class definitions. What are we doing wrong, or is the code duplication just a "necessary evil" of SOA?

• November 2012 Chicago IT Architects Group Meeting Recap

  - by Tim Murphy

  So the year is coming to an end.  A hearty few came out two days before Thanksgiving to discuss adopting agile in the enterprise.  While Norm Murrin claimed to be nervous about talking in front of a group your wouldn’t have known by his presentation.  He really made a topic that has always been hard to relate very personal.  This lead to some great discussion.  I came out of looking for ways to investigate agile further.  His presentation can be found here. This was our last meeting for the year.  We are looking forward to next year and are starting to line up some speakers and topics.  At this point we have an Azure presentation coming in February and are ironing out talks for January and March.  If your would like to join us and have topics you would like to see presented contact me through this blog.  Either leave a comment here or use the contact page.  I would love to hear from you. Have a great holiday season and we will see you next year. del.icio.us Tags: Chicago Information Technology Architects Group,CITAG,Agile,Norman Murrin

• Getting iTunes to play third party AAC files

  - by Redmastif

  I have a library filled with some old MP3 files and I'm in the process of changing them all to AAC for the better sound quality. Obviously I can't just create AAC versions of the files I already have because they would sound worse (lossy compression to converted to more lossy compression), so I'm going to their source and downloading them in a lossless form and using a third party to make them into AAC. Apparently iTunes will not handle AAC files that aren't made with iTunes. Is there a way around this? I've looked at third party programs and would be willing to use them, but since they all require the iTunes/iPod/iEverything driver, I don't know if they would still prevent my files or not. Also before you jump on my back about pirating, these files are from old CDs that I lost years ago. I paid for them. Thanks.

• How can I make multiple displays work on my Asus UX32VD?

  - by oKtosiTe

  Original title: Why do I have two trash icons in the Unity Launcher? Whether I run Ubuntu as a live-USB or install it, I always have two trash bins on the Unity Launcher. Both work, and both open the same location. This seems a bit redundant; what could be done about it? Update: Turning auto-hide on made it obvious that I have multiple Launchers showing. With auto-hide off, they simply overlap, making it look like there's a double trash icon, but with auto-hide enabled, I can display one Launcher (and therefore one trash icon) at a time. Still, two are running simultaneously. Second update: This problem appears to be caused by the way Ubuntu handles multiple displays on my Asus UX32VD Ultrabook. Somehow, the laptop display cannot be used while my external display is connected. It is shown in the Displays list, but remains black no matter how I configure it. The external display runs at 1920x1200, the laptop monitor should run at 1920x1080. It therefore becomes obvious that the Launcher that's supposed to run on the laptop display, is actually displayed on the external monitor. Using nomodeset as a kernel parameter as indicated here makes the laptop display inaccessible altogether, detecting the external monitor as the laptop display and making resolutions other than 1920x1200 inaccessible. That is not an option.

• How to access a fake raid?

  - by maaartinus

  I have a fake raid, which I wanted to access using mdadm /dev/md0 -A -c 128 -l stripe --verbose /dev/sda /dev/sdc which should be right, as far as I understand the man page. But I get the message mdadm: option -l not valid in assemble mode leaving the offending option out leads to mdadm: failed to create /dev/md0 and (despite verbose) no more information. I'm assuming that -A requires some mdadm-specific header which is obviously missing. I probably need to use "build" instead of assemble, but from the description I'm really unsure whether this is a non-destructive operation. Is it? What should I exactly do? UPDATE I see I haven't made clear, that the array already exists as a fake-raid (I can't give the details about my mainboard now). It looks like doing nothing except for interleaving blocks, so I hoped it could be easily done using mdadm, too. Maybe I'm completely wrong, but all the info I've found was concerned with booting from fake-raid, what I don't really need. I'd be happy with a read access for now.

• Slap the App on the VM for every private cloud solution! Really ?

  - by Anand Akela

  One of the key attractions of the general session "Managing Enterprise Private Cloud" at Oracle OpenWorld 2012 was an interactive role play depicting how to address some of the key challenges of planning, deploying and managing an enterprise private cloud. It was a face-off between Don DeVM, IT manager at a fictitious enterprise 'Vulcan' and Ed Muntz, the Enterprise Manager hero .   Don DeVM is really excited about the efficiency and cost savings from virtualization. The success he enjoyed from the infrastructure virtualization made him believe that for all cloud service delivery models ( database, testing or applications as-a-service ), he has a single solution - slap the app on the VM and here you go . However, Ed Muntz believes in delivering cloud services that allows the business units and enterprise users to manage the complete lifecycle of the cloud services they are providing, for example, setting up cloud, provisioning it to users through a self-service portal ,  managing and tuning the performance, monitoring and applying patches for database or applications. Watch the video of the face-off , see how Don and Ed address some of the key challenges of planning, deploying and managing an enterprise private cloud and be the judge ! ?

• Switching PHP to FastCGI from mod_php broke AMFPHP

  - by wezzy

  Hi, i've just switched my debian server from mod_php to fastcgi following this tutorial everything goes right but now i've found that one of the hosted application that using AMFPHP for flash remoting is broken. I'm trying to understand what's happend. Looking at it with FireBug and FireAMF it seems that the responses has a content but the Flash callbacks never get called and if i try to open the service browser it displays this error: (mx.rpc::Fault)#0 errorID = 0 faultCode = "Client.Error.RequestTimeout" faultDetail = "The request timeout for the sent message was reached without receiving a response from the server." faultString = "Request timed out" message = "faultCode:Client.Error.RequestTimeout faultString:'Request timed out' faultDetail:'The request timeout for the sent message was reached without receiving a response from the server.'" name = "Error" rootCause = (null) It's strange it seems that the server takes a long time to responde, then (in the service browser) flash made a new call to the server and the old one get a response. Some problem with sessions ? Really no idea ....

• Will We See More Partisan Splits from the SEC?

  - by Theresa Hickman

  The SEC's lawsuit against Goldman Sachs has made recent headlines. The fact that the SEC seems to be growing more litigious by making examples out of invididuals and companies is not the topic of my blog. The most interesting thing about this case is that the 5 SEC commissioners did not vote unanimously to bring the lawsuit. The commissioners had a 3-2 partisan split. Ms. Shapiro (a registered independent) voted with the 2 Democrats. Split votes rarely happen by the SEC, especially when they are enforcing actions against firms they regulate. I wonder if we will be seeing more of these partisan split votes when it comes to other decisions, say IFRS adoption? I know both the Democrats and Republicans have stated that they support a unified accounting standard. However, will the Republicans want to push back simply because there is a Democrat in office? (Seems childish to me, but I never understood politics). I think Ms. Shapiro will most definitely want a unanimous consensus related to the IFRS topic. There is already talk that we will be seeing more SEC split votes in the future. For example, there will most likely be a split vote regarding Obama's proposed financial-regulatory overhaul. I don't see why IFRS would be exempt. I really hope it doesn't happen because the last thing we need is more road blocks on our IFRS road trip.

• Fiction that includes BASIC programs [closed]

  - by Clinton Blackmore

  Back in what must've been the mid-80s, when every microcomputer included BASIC and Choose Your Own Adventure Books were really popular, there were some novels that had BASIC programs listed in the text, for you to type in and further enjoy. For example, as I recall, in one of these books, the adventurers were infiltrating an undersea base (and eventually wiped the bad guy's data storage [I do believe it was a hard drive, even though they were uncommon then]). One of the programs involved a game were you piloted a submarine and had to avoid or shoot sharks. The code was in BASIC; minor changes (such as 'CLS' - 'HOME') had to be made for your specific computer, and it used good old 40-column text-mode to display the action. IIRC, the plot never depended upon the programs. My question is, does anyone else recall these sorts of books? Do you know any titles that I could look for, or of any online? I am toying with the idea of writing a story like this (no, not in BASIC!), and would really like to see how it was done, back in the day.

• Should we test all our methods?

  - by Zenzen

  So today I had a talk with my teammate about unit testing. The whole thing started when he asked me "hey, where are the tests for that class, I see only one?". The whole class was a manager (or a service if you prefer to call it like that) and almost all the methods were simply delegating stuff to a DAO so it was similar to: SomeClass getSomething(parameters) { return myDao.findSomethingBySomething(parameters); } A kind of boilerplate with no logic (or at least I do not consider such simple delegation as logic) but a useful boilerplate in most cases (layer separation etc.). And we had a rather lengthy discussion whether or not I should unit test it (I think that it is worth mentioning that I did fully unit test the DAO). His main arguments being that it was not TDD (obviously) and that someone might want to see the test to check what this method does (I do not know how it could be more obvious) or that in the future someone might want to change the implementation and add new (or more like "any") logic to it (in which case I guess someone should simply test that logic). This made me think, though. Should we strive for the highest test coverage %? Or is it simply an art for art's sake then? I simply do not see any reason behind testing things like: getters and setters (unless they actually have some logic in them) "boilerplate" code Obviously a test for such a method (with mocks) would take me less than a minute but I guess that is still time wasted and a millisecond longer for every CI. Are there any rational/not "flammable" reasons to why one should test every single (or as many as he can) line of code?

• Does reformatting the drive really removes spywares and viruses

  - by user23950

  I've recently read that the data that you deleted in windows using shift+del doesn't actually get deleted it is just made to be overwritable by other data that will soon be stored in your hard drive. And just marked as deleted. And there are some articles like this: http://www.howtogeek.com/howto/15037/use-an-ubuntu-live-cd-to-securely-wipe-your-pcs-hard-drive/ that shows how to completely wipe out the hard drive of all the data. And thus the data can't be recovered even by the most advanced software for recovering deleted data. Now my question is, does spyware, virus or other harmful really are lost forever if you reformat your drive?

• A quick hello to the Western Kentucky .NET User Group

  - by Muljadi Budiman

  A few days back, I got a chance to speak at the Western Kentucky .NET User Group meeting in Murray, Kentucky.  The opportunity came up because the original speaker, Jeff Blankenburg, had another obligation and was thus unable to come to this meeting.  I volunteered to deliver his presentation, which is an overview of MIX10 conference. It was a great experience for me; got to drive around and do a little bit of sight-seeing – can’t say I’ve ever been to Kentucky before, so first trip ever there.  I got to meet the user group’s current lead, Tom Turner and got to chat and discuss about all kinds of stuff with the other members.  Cheers to Matt Gawarecki and Brandon Sharp! The presentation itself mostly covers new features in Visual Studio 2010, which was recently released on April 12 – got to demonstrate Historical Debugging in IntelliTrace, Parallel Stacks, View Call Hierarchy and show some Extensions.  We also covered some of the new functionalities in Silverlight 4 (using webcams, drag & drop support among others) and I got to show off Scott Guthrie’s Windows Phone 7 Twitter app.  Altogether, it was quite a bit to cover in 70 minutes or so, but I think everyone enjoyed it. Jeff provided me with the presentation slides (which I modify a bit) and demo applications; so I’m putting it up here for those that may be interested in downloading them.  Please keep in mind that all the demos were made with VS2010 RC, so there may be slight tweaks to get it to work on the RTM version.

• Terminal/Putty showing control characters (^M) after updating

  - by jaycee48

  I updated my system yesterday afternoon using the recommended updates from Update Manager. After it completed, I shutdown my system and went home for the day. I come in this morning and I am getting control characters displayed when using vi in both the standard terminal emulator, putty, and putty inside of my Windows virtual that I run with VirtualBox. I have made no other system changes and I cannot figure out how this occurred. It's as if every text file I have was created in DOS. I've searched the forums and I haven't found any answers. I am using xterm as my emulator and I checked with 3 of my coworkers and none of them are having this problem so we do not believe it is a server side issue. Especially since I've checked 3 different servers. There's nothing in my .profile other than PATH variables so I'm using the same terminal settings as everyone else. Some files are fine (I can open and read both /etc/environment and my .profile) but most of any kind of server generated log file is trash. Running cat or head on the same file displays the contents without the characters. Any ideas would be appreciated. Thanks.

• Java SE 8 (with JavaFX) Developer Preview Release for ARM

  - by Roger Brinkley

  In an effort to get ARM developers testing Java SE 8 before the scheduled release later this year a Java SE 8 Developer Preview Release for ARM has been made available. This release has been tested on the Raspberry PI but should work on other ARM platforms. In addition to the new Java SE features, this release provides specific support of hard float GPU on the Raspberry PI. The support for hard float GPU has been anticipated by a number of developers. Additionally, this release includes support of an optimized JavaFX. Specific configurations of JDK 8 on ARM are defined below: Java FX is supported on ARM architecture v6/7 (hard float) Supported platforms without Java FX: ARM architecture v6/7 (hard float) ARM architecture v7 (VFP, little endian) ARM architecture v5 (soft float, little endian) Linux x86 The download page includes setup instructions for a Raspberry PI device as well as demos and samples. Developers are also encouraged to try their own applications as well and to share their stories via the JavaFX or Project Feedback Forums.  If you've got a Raspberry PI or other ARM devices it's time to get started with Java SE 8 Developer Preview release.

• Brain picking during job interview

  - by mark

  Recently, I had a job interview at a big Silicon Valley company for a senior software developer/R&D position. I had several technical phone screens, an all day on-site interview and more technical phone screens for another position later. The interviews went really well, I have a PhD and working experience in the area I was applying for yet no offer was made. So far, so good. It was an interesting experience, I am employed, absolutely no hard feelings about this. Some of the interviewers asked really detailed questions to the point of being suspicious about new technologies I have been working on. These technologies are still in development and have not come to market yet. I know some major hardware/software companies are working on this too. I have had many interviews before and based on my former interviewing experience and the impression some of the interviewers left behind, I know now all this company wanted from me is to extract some ideas about what I did in this field. Remember, I am referring to a R&D position, not the standard software developer stuff. Has anybody encountered this situation so far? And how did you deal with it? I am not so much concerned about "stealing" ideas but more about being tricked into showing up for an interview when there is no intension to hire anyway. I am considering refusing technical interviews in the future and instead proposing a trial period in which the company can easily reconsider its hiring decision.

• Making Multilingual J! 1.5 + + Joomfish + VM 1.17 more workable

  - by rhand

  I have been working with a multilingual Joomla! 1.5.23 e-commerce website for a client for quite a while and made several customizations. But the client is still not happy he has to adjust content at at least three locations: Joomfish Virtuemart Article Manager Joomfish is nice in the way that it allows you to create multilingual content and copy and paste the source language on the same page, which makes translation work easier but it is annoying in the way you have to edit several custom fields at different locations/ content types. As Joomla! source language content still needs to be created in the article manager first this is the second location the client has to work at. The third location is Virtuemart. Here all the products and product categories are created. And here we added some custom fields as well. Now I was considering upgrading the website to Joomla 1.7 or later on to 1.8. This J! versions have better multilingual support. But I wonder if er can really make the client's life easier. We will still have to copy the source language to a new article and create content in another language. We will still have the issue of content in custom fields that needs to be translated and we will still have to create content. Should I go for another CMS such as Magento or do you think there is a way in a more recent Joomla! version to work with all content in one or max two locations?

• Bejeweled-like game, managing different gem/powerup behaviors?

  - by Wissam

  I thought I'd ask a question and look forward to some insight from this very compelling community. In a Bejeweled-like (Match 3) game, the standard behavior once a valid swap of two adjacent tiles is made is that the resulting matching tiles are destroyed, any tiles now sitting over empty spaces fall to the position above the next present-tile, and any void created above is filled with new tiles. In richer Match-3 games like Bejeweled, 4 in a row (as opposed to just 3) modifies this behavior such that the tile that was swapped is retained, turned into a "flaming" gem, it falls, and then the empty space above is filled. The next time that "flaming gem" is played it explodes and destroys the 8 perimeter tiles, triggers a different animation sequence (neighbors of those 8 tiles being destroyed look like they've been hit by a shockwave then they fall to their respective positions). Scoring is different, the triggered sounds are different, etc. There are even more elaborate behaviors for Match5, Match-cross-pattern, and many powerups that can be purchased, each which produces a more elaborate sequence of events, sounds, animations, scoring, etc... What is the best approach to developing all these different behaviors that respond to players' "move" and her current "performance" and that deviate from the standard sequence of events, scoring, animation, sounds etc, in such a way that we can always flexibly introduce a new "powerup" ? What we are doing now is hard-coding the events of each one, but the task is long and arduous and seems like the wrong approach especially since the game-designers and testers often offer (later) valuable insight on what works better in-game, which means that the code itself may have to be re-written even for minor changes in behavior (say, destroy only 7 neighboring tiles, instead of all 8 in an explosion). ANY pointers for good practices here would be highly appreciated.

• May the file size returned by stat be compromised?

  - by codeholic

  I want to make sure that nobody changed a file. In order to accomplish that, I want not only to check MD5 sum of the file, but also check its size, since as far as I understand this additional simple check can sophisticate falsification by several digits. May I trust the size that stat returns? I don't mean if changes were made to stat itself. I don't go that deep. But, for instance, may one compromise the file size that stat returns by hacking the directory file? Or by similar means, that do not require superuser privileges? It's Linux.
