  • What are the main differences between SRV records and TXT records?

    - by Chris Adams
    Hi there, I'm trying to consolidate domain names for the servers I look after to just use one panel instead of 3 or 4, and one thing stopping me is that the provider I originally wanted to move them to only lets me the following kinds of records: A MX NS CNAME TXT The first four I understand, but I'm not sure about the relationship (if any) between SRV records and TXT records. Can I use TXT records in the place of SRV records? They both seem to be general text records to just point at a particular server without needing to specify a particular protocol, so it doesn't sound like a totally unreasonable assumption, but I'd rather check here before I break something. If I can only set the above records, does that mean I'm essentially unable to so any SRC record redirecting? Thanks!

  • I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

    - by Shin San
    I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

  • What is logical cohesion, and why is it bad or undesirable?

    - by Matt Fenwick
    From the c2wiki page on coupling & cohesion: Cohesion (interdependency within module) strength/level names : (from worse to better, high cohesion is good) Coincidental Cohesion : (Worst) Module elements are unrelated Logical Cohesion : Elements perform similar activities as selected from outside module, i.e. by a flag that selects operation to perform (see also CommandObject). i.e. body of function is one huge if-else/switch on operation flag Temporal Cohesion : operations related only by general time performed (i.e. initialization() or FatalErrorShutdown?()) Procedural Cohesion : Elements involved in different but sequential activities, each on different data (usually could be trivially split into multiple modules along linear sequence boundaries) Communicational Cohesion : unrelated operations except need same data or input Sequential Cohesion : operations on same data in significant order; output from one function is input to next (pipeline) Informational Cohesion: a module performs a number of actions, each with its own entry point, with independent code for each action, all performed on the same data structure. Essentially an implementation of an abstract data type. i.e. define structure of sales_region_table and its operators: init_table(), update_table(), print_table() Functional Cohesion : all elements contribute to a single, well-defined task, i.e. a function that performs exactly one operation get_engine_temperature(), add_sales_tax() (emphasis mine). I don't fully understand the definition of logical cohesion. My questions are: what is logical cohesion? Why does it get such a bad rap (2nd worst kind of cohesion)?

  • Fix a jQuery/HTML5 dynamic content issue by upgrading jQuery

    - by Steve Albers
    The default NuGet template for MVC3 pushes down jQuery 1.5.1.  You can upgrade to a new version (1.7.1 is current when this is written) to avoid a problem with the creation of “unknown” HTML5 tags in IE6-8: Take this sample HTML page using HTML5Shiv to provide support for new HTML5 tags in IE6 – IE8.  The page has a number of <article> tags that are backwards compatible in Internet Explorer 6-8 thanks to the HTML5Shiv. After the article elements there is a jQuery 1.5.1 script tag, and a ready() event handler that appends a footer element with a copyright to each of the article tags.  This appears correctly in IE9, but in older IE browsers the unknown tag problem reappears for the dynamic <footer> elements, even though we have the HTML5Shiv at the top of the page.  The copyright text sits outside of the two separate footer tags. To solve the issue upgrade your jQuery files to an up-to-date version.  For instance in Visual Studio 2010: In the Solution Explorer right click on References and choose Manage NuGet Packages. In the Manage NuGet Packages window select the jQuery item on the middle of the page and click the “Upgrade” button. You may need to upgrade your script src references to point at the new version. Using the updated jQuery library the incorrect tags should disappear and styles should work properly:   You can find more information about the issue on the jQuery Bug Tracker site.

  • starting up with VPS or cloud hosting? [closed]

    - by FlyOn
    Possible Duplicate: How to find web hosting that meets my requirements? Summary: I want to start hosting my product. I'd like to register domains (at some point). I'm a linux beginner. Thinking about scalability and price, I'm thinking am I better off on a VPN to get started or would some form of cloud hosting be better (not being familiar with either). Full question: I'm creating a product where people can create their own 3D representations of whatever data / info they have, and (re)organise that data. The product is coming along beautifully on my local environment, but it's about time I start getting some form of hosting ready, and I could really use some advice where / how to get started: I'd like people to be able to move/register their own domains on my server. I could start without this just to demo the product, but it would be the very first on the todo list. I'd like to automatically copy some files / install databases etc for each domain. I probably want to see if I can let users manage their own subdomains at some points, but for now: I'd like start as simple as possible. I've always on a windows machine, so my linux experience is quite basic. I really don't mind getting into it, but I'm thinking it's better to get my product out first of all and see where to go from there. Although... I'd like things to be scalable. If I set up some reseller VPN now which only scales to 100 domains or so, which means I have to set up something else / move again when I pass that level, or which means that I'm in trouble if I suddenly get lots of new customers... hmm. Finally, I need to start cheap. I'm putting all I have into starting this company, and live on very little. So before I have any customers, 50 dollars a month is a fair bit and 100 dollars a month may be too much. If anyone has some tips to help get me started I'd be really grateful.

    Here's the situation I'm in. I have Acrobat 8 on Wows 7 (64-bit) and anytime I create PDFs any numbers on the page I'm PDFing come through as garbage. Everything else on the page comes out fine, just the numbers are messed up. They appear as random symbols. I've uninstalled, reinstalled. Applied all updates, not applied updates, nothing seems to help. Mayube I'm a bad searcher, can't put in the right search terms, but I can't find anything that seems to point me in a direction on this. ANy ideas?

  • What is the difference between a plain Amazon ec2 instance and beanstalk?

    - by Alex Ford
    I am a solo developer and the sites I'm deploying are very small, usually hobby sites and I have a few questions about the Amazon services. Is there a reason for me to use beanstalk or should I just stick with a single ec2 instance? Should I use RDS for database? I heard someone say that I could just install a database on my ec2 instance, making it cheaper. I'm trying to keep everything as cheap as possible. I need to point custom domains to my sites. Pretty sure that means I have to deal with elastic IPs. Do those work with beanstalk or only with individual ec2 instances? Thanks in advance!

  • Getting Help with 'SEPA' Questions

    - by MargaretW
    What is 'SEPA'? The Single Euro Payments Area (SEPA) is a self-regulatory initiative for the European banking industry championed by the European Commission (EC) and the European Central Bank (ECB). The aim of the SEPA initiative is to improve the efficiency of cross border payments and the economies of scale by developing common standards, procedures, and infrastructure. The SEPA territory currently consists of 33 European countries -- the 28 EU states, together with Iceland, Liechtenstein, Monaco, Norway and Switzerland. Part of that infrastructure includes two new SEPA instruments that were introduced in 2008: SEPA Credit Transfer (a Payables transaction in Oracle EBS) SEPA Core Direct Debit (a Receivables transaction in Oracle EBS) A SEPA Credit Transfer (SCT) is an outgoing payment instrument for the execution of credit transfers in Euro between customer payment accounts located in SEPA. SEPA Credit Transfers are executed on behalf of an Originator holding a payment account with an Originator Bank in favor of a Beneficiary holding a payment account at a Beneficiary Bank. In R12 of Oracle applications, the current SEPA credit transfer implementation is based on Version 5 of the "SEPA Credit Transfer Scheme Customer-To-Bank Implementation Guidelines" and the "SEPA Credit Transfer Scheme Rulebook" issued by European Payments Council (EPC). These guidelines define the rules to be applied to the UNIFI (ISO20022) XML message standards for the implementation of the SEPA Credit Transfers in the customer-to-bank space. This format is compliant with SEPA Credit Transfer version 6. A SEPA Core Direct Debit (SDD) is an incoming payment instrument used for making domestic and cross-border payments within the 33 countries of SEPA, wherein the debtor (payer) authorizes the creditor (payee) to collect the payment from his bank account. The payment can be a fixed amount like a mortgage payment, or variable amounts such as those of invoices. The "SEPA Core Direct Debit" scheme replaces various country-specific direct debit schemes currently prevailing within the SEPA zone. SDD is based on the ISO20022 XML messaging standards, version 5.0 of the "SEPA Core Direct Debit Scheme Rulebook", and "SEPA Direct Debit Core Scheme Customer-to-Bank Implementation Guidelines". This format is also compliant with SEPA Core Direct Debit version 6. EU Regulation #260/2012 established the technical and business requirements for both instruments in euro. The regulation is referred to as the "SEPA end-date regulation", and also defines the deadlines for the migration to the new SEPA instruments: Euro Member States: February 1, 2014 Non-Euro Member States: October 31, 2016. Oracle and SEPA Within the Oracle E-Business Suite of applications, Oracle Payables (AP), Oracle Receivables (AR), and Oracle Payments (IBY) provide SEPA transaction capabilities for the following releases, as noted: Release 11.5.10.x -  AP & AR Release 12.0.x - AP & AR & IBY Release 12.1.x - AP & AR & IBY Release 12.2.x - AP & AR & IBY Resources To assist our customers in migrating, using, and troubleshooting SEPA functionality, a number of resource documents related to SEPA are available on My Oracle Support (MOS), including: R11i: AP: White Paper - SEPA Credit Transfer V5 support in Oracle Payables, Doc ID 1404743.1R11i: AR: White Paper - SEPA Core Direct Debit v5.0 support in Oracle Receivables, Doc ID 1410159.1R12: IBY: White Paper - SEPA Credit Transfer v5 support in Oracle Payments, Doc ID 1404007.1R12: IBY: White Paper - SEPA Core Direct Debit v5 support in Oracle Payments, Doc ID 1420049.1R11i/R12: AP/AR/IBY: Get Help Setting Up, Using, and Troubleshooting SEPA Payments in Oracle, Doc ID 1594441.2R11i/R12: Single European Payments Area (SEPA) - UPDATES, Doc ID 1541718.1R11i/R12: FAQs for Single European Payments Area (SEPA), Doc ID 791226.1

  • How to dispose of old rack-mount servers?

    - by Nic
    I have two old rack-mount servers lying around that I want to get rid of. One is a HP DL380 G2, the other is an IBM from the same era. Both machines boot up, but I don't have any harddrives for them, or any use for them. Worse yet, both machines appear to have been dropped at some point and the rail kits are bent out of shape and can't be removed, making them unusuable in a rack environment. I'd like to recycle them or dispose of them in some kind of safe manner, but don't really know what my options are. I'm in western Canada. Any suggestions? Update: If you found this question interesting, please consider visiting StackExchange Area 51 to support the proposal for a dedicated Recycling Q&A site.

  • Apache SSL for login and NON-SSL for everything else (.htacces)

    - by The Devil
    Hey I've almost figured it out on my own but there's something I'm missing. I want to set a couple of directories and files to require SSL and everything else that's not related to those files and dirs to point back to http. So far I have this: RewriteEngine on RewriteBase / # Force ssl for login & admin RewriteCond %{HTTPS} !on RewriteRule ^/?(admin(.*)|login\.php)$ https://%{SERVER_NAME}/$1 [R,NC,L] # Force non-ssl for others RewriteCond %{HTTPS} on RewriteRule ^/?(admin(.*)|login\.php)$ http://%{SERVER_NAME}/$1 [R,NC,L] I'm sure I'm doing something wrong but I just can't figure it out.... The first condition works perfect - whenever I access login.php or /admin/ it points to https. But the second one doesn't... Where have I mistaken ? Thanks in advance!

  • setting up my own name server

    - by mmokh
    I'm in the process of setting up my own name servers using BIND9, however I want to visualize the name server setup in relation to registrars and other name servers. Say I have a domain www.mydomain.com I setup my 2 name servers: ns1.mydomain.com - 192.168.0.1 ns2.mydomain.com - 192.168.0.2 1) How does the world know that my name servers are now at ns1.mydomain and ns2.mydomain. I read about setting up glue records at my registrar. Could you please elaborate on this, i.e. once i setup these glue records, can I now use my name servers in NS records for any other domain? For e.g. NS records for www.otherdomain.com - ns1.mydomain.com/ns2.mydomain.com 2) Given I setup the glue records as mentioned above, do I "have to" update mydomain.com NS records to point to my name servers? Can I keep mydomain.com NS records pointing to my registrars name servers, however use ns1.mydomain.com/ns2.mydomain.com as name servers for any other domain I own? Thanks

  • RewriteRule Works With "Match Everything" Pattern But Not Directory Pattern

    - by kgrote
    I'm trying to redirect newsletter URLs from my local server to an Amazon S3 bucket. So I want to redirect from: https://mysite.com/assets/img/newsletter/Jan12_Newsletter.html to: https://s3.amazonaws.com/mybucket/newsletters/legacy/Jan12_Newsletter.html Here's the first part of my rule: RewriteEngine On RewriteBase / # Is it in the newsletters directory RewriteCond %{REQUEST_URI} ^(/assets/img/newsletter/)(.+) [NC] # Is not a 2008-2011 newsletter RewriteCond %{REQUEST_URI} !(.+)(11|10|09|08)_Newsletter.html$ [NC] ## -> RewriteRule to S3 Here <- ## If I use this RewriteRule to point to the new subdirectory on S3 it will NOT redirect: RewriteRule ^(/assets/img/newsletter/)(.+) https://s3.amazonaws.com/mybucket/newsletters/legacy/$2 [R=301,L] However if I use a blanket expression to capture the entire file path it WILL redirect: RewriteRule ^(.*)$ https://s3.amazonaws.com/mybucket/newsletters/legacy/$1 [R=301,L] Why does it only work with a "match everything" expression but not a more specific expression?

  • Handling FreeBSD package upgrades using pkg_add

    - by larsks
    I'm trying to use FreeBSD's pkg_add command to install and upgrade binary packages in a build-once-install-on-multiple-machines sort of scenario. It works well when installing a new package, but upgrades are baffling me. For example, if I want to upgrade a package that is depended on by another package, I can't just install it: # pkg_add /path/to/somepackage-2.0.tbz pkg_add: package 'somepackage' or its older version already installed At this point, I can delete the older version of the package if I pass -f to the pkg_delete command: # pkg_delete -f somepackage-1.0 pkg_delete: package 'somepackage-1.0' is required by these other packages and may not be deinstalled (but I'll delete it anyway): anotherpackage-1.0 But...and this is the killer...now the dependency information is gone! I can install the upgrade: # pkg_add /path/to/somepackage-2.0.tbz And now attempts to delete it will succeed without any errors: # pkg_delete somepackage-2.0 How do I handle this gracefully (whereby "gracefully" means "in a fashion that preserves dependency information without requiring me to rebuild/reinstall and entire dependency chain"). Thanks!

  • Make shortened and long urls play together on the same domain (RewriteRule).

    - by Renato Renato
    Long story short, I want to have both example.com/aJ5 and example.com/any-other-url working together. I'm using apache and not very good at writing regex. I have already a global RewriteRule which sends everything to the app entry point. What I need is to tell apache if length($path) is <= 5 chars then rewrite to another location. I know I can use {1,5} like syntax in regex, but don't really know if it's what I'm looking for. I'd like to implement this at web-server level rather than php level. Any help is appreciated.

  • Best triple head display setup

    - by dgel
    I'm currently running Ubuntu 12.04 with a darn good triple head display setup. I've got a VisionTek 900530 Radeon HD 5450 512MB DDR3 PCI Express video card that has two DVI outputs and one Mini DisplayPort that I have connected to a HDMI adapter. I'm running three identical Asus 1920x1080 monitors that each have a DVI, VGA, and HDMI input. I'm using the xorg-edgers ppa, so I'm using the open source radeon driver version 6.99.99. I tried using the ATI binary fglrx driver, but I wasn't able to get the three monitors working properly- the monitor connected via HDMI / DisplayPort wouldn't run at full resolution. The setup is almost perfect: Compiz runs fine and is quite snappy. I'm not able to use that great compiz feature where you can drag a window to the side of a display and it will half maximize. I occasionally experience display corruption weirdness with Unity and need to restart it. When I use a dropdown menu in LibreOffice it often pops the menu down in another window. For example, if I'm using the center monitor and click the Insert menu, the menu pulls down on the monitor to my right, forcing me to chase it. If I chase down the menu and choose Manual Break, the dialog appears over on my left monitor. This absurdity is mildly entertaining but has lost its novelty. I've decided to build a new system and have spared no expense- latest i7 processor, SSD, etc. I really like the performance of the Nvidia binary drivers, so I put two ZOTAC ZT-40707-10L GeForce GT 440 in the system, figuring I'd have four DVI outputs and an awesome triple (or even eventually quad) head setup. Unfortunately it appears that I didn't do sufficient research before my purchase. It seems that Nvidia TwinView only supports two monitors on one card (I guess that's why they call it TwinView...). I messed around with running two X servers, but I really don't want that- being able to drag windows to any monitor is critical. It doesn't sound like Xinerama is an option because from what I understand it simply doesn't support Compiz. I've seen a BaseMosaic option that can be used with the Nvidia drivers that appears to support an almost unlimited number of heads- unfortunately me cheap little cards don't support it. I'm also not sure whether you'll still have all nice maximizing and snapping that TwinView provides, or whether Ubuntu will only see it as one massive display. I put my old trusty ATI card into my new system and installed 12.10. I'm using the opensource radeon drivers again because even in 12.10 I can't get the fglrx binary drivers to do triple head. Unfortunately, even with an unbelievably powerful system the experience is extremely sluggish (much more so than my experience in 12.04). The menu scattering problem appears to be fixed, but I get a lot of nasty Unity display corruption. So finally, my question is this: What hardware / drivers should I use? I'm willing to buy (almost) any video card(s). I have two PCI-Express 3.0 slots on my motherboard (which has an integrated Intel HD card). I'm willing to use ATI or Nvidia cards and willing to run Ubuntu 12.04.1 or 12.10. I'm not a gamer, but do want beautiful and snappy Compiz effects. Does anyone out there have the perfect triple head setup in 12.04 or 12.10? What hardware / drivers are you using? I have those two Nvidia cards but will probably be returning them unless someone knows a way to use them together for a triple head setup. Since I'm having pretty good luck with a single ATI card providing three displays, should I just buy a beefier one with the hopes that it will fix the horrible sluggishness I'm experiencing in 12.10?

  • Why the clip space in OpenGL has 4 dimensions?

    - by user827992
    I will use this as a generic reference, but the more i browser online docs and books, the less i understand about this. const float vertexPositions[] = { 0.75f, 0.75f, 0.0f, 1.0f, 0.75f, -0.75f, 0.0f, 1.0f, -0.75f, -0.75f, 0.0f, 1.0f, }; in this online book there is an example about how to draw the first and classic hello world for OpenGL about making a triangle. The vertex structure for the triangle is declared as stated in the code above. The book, as all the other sources about this, stress the point that the Clip Space is a 4D structure that is used to basically decide what will be rasterized and rendered to the screen. Here I have my questions: i can't imagine something in 4D, i don't think that a human can do that, what is a 4D for this Clip space ? the most human-readable doc that i have read speaks about a camera, which is just an abstraction over the clipping concept, and i get that, the problem is, why not using the concept of a camera in the first place which is a more familiar 3D structure? The only problem with the concept of a camera is that you need to define the prospective in other way and so you basically have to add another statement about what kind of camera you wish to have. How i'm supposed to read this 0.75f, 0.75f, 0.0f, 1.0f ? All i get is that they are all float values and i get the meaning of the first 3 values, what does it mean the last one?

  • Architecture of an action multiplayer game from scratch

    - by lcf
    Not sure whether it's a good place to ask (do point me to a better one if it's not), but since what we're developing is a game - here it goes. So this is a "real-time" action multiplayer game. I have familiarized myself with concepts like lag compensation, view interpolation, input prediction and pretty much everything that I need for this. I have also prepared a set of prototypes to confirm that I understood everything correctly. My question is about the situation when game engine must be rewind to the past to find out whether there was a "hit" (sometimes it may involve the whole 'recomputation' of the world from that moment in the past up to the present moment. I already have a piece of code that does it, but it's not as neat as I need it to be. The domain logic of the app (the physics of the game) must be separated from the presentation (render) and infrastructure tools (e.g. the remote server interaction specifics). How do I organize all this? :) Is there any worthy implementation with open sources I can take a look at? What I'm thinking is something like this: -> Render / User Input -> Game Engine (this is the so called service layer) -> Processing User Commands & Remote Server -> Domain (Physics) How would you add into this scheme the concept of "ticks" or "interactions" with the possibility to rewind and recalculate "the game"? Remember, I cannot change the Domain/Physics but only the Game Engine. Should I store an array of "World's States"? Should they be just some representations of the world, optimized for this purpose somehow (how?) or should they be actual instances of the world (i.e. including behavior and all that). Has anybody had similar experience? (never worked on a game before if that matters)

  • Where to Start?

    - by freemann098
    my name is Chase. I've been programming for over 3 years now and I've made very little progress towards game development. I blame myself for it due to reasons. I have experience in many languages such as C++, C#, and Java. I have a little bit of knowledge in JavaScript/HTML and Python. My question is where to start on actually understanding jumping into game development. Whenever I watch game development tutorials it mostly makes sense until points of things like OpenGL or advanced topics that make no sense at all. An example is something like glOrhho Matrix or whatever. Videos either don't explain things like this or they're not explained very well. Do I not know enough basics? I find myself always copying code from a video but understanding very little of it. It's like i'm memorizing things I don't understand which makes it hard to program at all. If I were to want to get to the point where I could write my own game engine or just a game by myself in general in C++ using at the most documentation how would I start at mastering to that level. Should I learn C first, or get really good at basics in general with C++. I know there is a similar posted question on this site but it's not the same due to the fact the person asking the question has a well knowledge level in programming. I'm stuck in a loop of learning the same things but if I go farther I don't understand. I'm stuck in the same spot and need to make progress.

  • Why don't C++ Game Developers use the boost library?

    - by James
    So if you spend any time viewing / answering questions over on Stack Overflow under the C++ tag, you will quickly notice that just about everybody uses the boost library; some would even say that if you aren't using it, you're not writing "real' C++ (I disagree, but that's not the point). But then there is the game industry, which is well known for using C++ and not using boost. I can't help but wonder why that is. I don't care to use boost because I write games (now) as a hobby, and part of that hobby is implementing what I need when I am able to and using off-the-shelf libraries when I can't. But that is just me. Why don't game developers, in general, use the boost library? Is it performance or memory concerns? Style? Something Else? I was about to ask this on stack overflow, but I figured the question is better asked here. EDIT : I realize I can't speak for all game programmers and I haven't seen all game projects, so I can't say game developers never use boost; this is simply my experience. Allow me to edit my question to also ask, if you do use boost, why did you choose to use it?

Here's the output before it was running: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 15624 186660 39460 439052 0 0 0 2 1 1 0 0 100 0 Here's the output while the script is running, at the point where free memory was at its lowest value: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 15624 11464 40312 473524 0 0 0 2 1 1 0 0 100 0 So free memory dropped by about 175 MB, and I expected that buff would increase by that amount. But it seems the other columns changed by relatively negligible amounts - how is this possible? Am I interpreting this wrong, or is some memory just not being accounted for in this output?

  • View another persons calendar details in Outlook 2010

    - by SqlRyan
    I know how to view somebody else's calendar - there are 100 walk-throughs like this one on Google. However, this feature has changed in Outlook 2010, and you no longer get prompted for rights to view another person's calendar, and Outlook just displays their "Free/Busy" information, which doesn't help me. I'd like to request permissions to view the details of their appointments, but I can't find any place to request permissions on their calendar - Outlook 2010 just gives me "Free/Busy" rights and then appears to have no option to request additional rights. Can anybody point me in the right direction?

  • Security of a free public VPN service

    - by Mark Belli
    I just started using VPNBOOK, which is a (very efficent) free VPN solution. I have a question: VPNBOOK user and pass used to connect to their vpn network are publicily available on their homepage; everybody uses them to connect to the vpn. Can a user intercept my wifi traffic and: Understand that my connections are directed to VPNBOOK servers. If point 1 is successful, then they could use VPNBOOK public user and pass to decrypt my traffic? I hope I am missing something, otherwise it would be a very big weakness and I would revert to a paid service (with a private account)

  • rsnapshot intervals in configuration file...

    - by Patrick
    A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily
