• Printing Booklet Page Size in Adobe Reader 4-in-1

  - by Justin Nathanael Waters

  So I have a 70 page pdf document that I'm trying to condense to a small booklet. I tried creating a formula to manually to perform it but it got ugly fast. 35,36,34,37,17,54,16,55,33,38,32,39,15,56,14,57,31,40,30,41,13,58,12,59 29,42,28,43,11,60,10,61,27,44,26,45,9,62,8,63,25,46,24,47,7,64,6,65 23,48,22,49,5,66,4,67,21,50,20,51,3,68,2,69,19,52,18,53,1,70 Once I print the booklet I should be able to cut the sheets in half and set the bottom half behind the top and staple it for a simple book. Which means Page 1 should have pages 35,36,17,54,34,37,16,55 Page 2 should have pages 33,38,15,56,32,39,14,57 And several pages later Page 9 should have pages 19,52,1,70,18,53 But manually doing this is a headache and it seems like the booklet function should contain functionality that can perform this. I'm using a commercial Konica Minolta C452

• How to trigger chef-client on all nodes from my workstation

  - by divyanshm

  I have 5 nodes and all of them have one setup cook-book in common. Now I would like to add another task in this common cookbook that would configure SQL server for me on all the nodes. Is there a way/command to manually trigger this change across all clients right away? I use azure VM's. All the nodes are Windows Server 2012 machines. I could do a knife winrm machine-name chef-client -m -x username -P password on all the machines, but i'm sure there should be a better way of doing this. I'm new to using chef, so I might be missing a very basic command here.

• time on files differ by 1 sec. FAIL Robocopy sync

  - by csmba

  I am trying to use Robocopy to sync (/IMG) a folder on my PC and a shared network drive. The problem is that the file attributes differ by 1 sec on both locations (creation,modified and access). So every time I run robocopy, it syncs the file again... BTW, problem is the same if I delete the target file and robocopy it from new... still, new file has 1 sec different properties. Env Details: Source: Win 7 64 bit Target: WD My Book World Edition NAS 1TB which takes its time from online NTP pool.ntp.org (I don't know if file system is FAT or not)

• Bringing my Dell XPS 13 ultrabook back to factory state

  - by TysHTTP

  I have a brand new Dell XPS 13 ultra book. After i picked it up at the store, i wiped the exising partitions which also contained the restore/rescue data, which you need to reinstall the factory version of Windows 8 that comes with this machine. I did this because we have a different MS partner edition of Windows which i prefer to run. After doing all this, i noticed that there was something wrong with machine. No real damage, but the specs are not completely as they should be. Turned out that a simple mistake while ordering. Now, long story short, the shop says that it has no problem with taking the product back, as long as it is in it's original state. And this is the problem i'm having, because i formatted the original partitions that contain that rescue option / windows 8 setup, i don't have a clue whether it's possible to get back to that original. Does anyone have an idea on how to get this fixed?

• Restoring the Fonts folder by using a restore point

  - by ryalho

  I am an idiot. Who would have thought that installing 2 gigs of fonts would be detrimental to the boot up time for the most common design programs such as adobe illustrator. I would like to restore the font folder because I am no longer able to just delete the fonts. It takes too long. So when I right-click the fonts folder and select "Restore Previous Versions" I am able to find a restore point, but the "Restore" button is greyed out. this leads me to think that I cannot change the settings of files in the windows directory. Oh and there are 34,000 fonts I need gone. Thanks

• How to use HFS formatted pen drive in Windows 7?

  - by row-sun

  I recently used disk utility in my mac book pro to format my 8 GB pen drive to install OS X. After that I formatted my pen drive from disk utility as FAT32 so that I would be able to use it in windows. But in windows the pen drive does not show up. When I right click on my computer and click manage and then disk management, the pen drive is listed there, but it doesn't show up in the explorer and I cant use it. I tried to do many things but I'm still not being able to use it in windows though I can use it in Mac OS X. Could anyone help? Thanks.

• Good bitmap fonts with big sizes and unicode support

  - by bitonic

  I really like bitmap fonts for programming/terminal. As far as I know there are two bitmap fonts with good unicode support: Unifont Fixed The problem is that I have a really high resolution screen, and they're both too small. Fixed does include a large size (10x20) but it looks really bad (it's basically always bold, and bold is a different face). Are there any other bitmap fonts with unicode support and large sizes? Terminus is the only font with a decent size but it doesn't have good unicode support. Having good coverage for mathematical symbols would be enough, since that's what I need.

• Split or individually edit repeating Google Calendar events

  - by Steve Crane

  Our company just moved from Microsoft Exchange with Outlook to Google Mail, Calendar, etc. and I am trying to modify a calendar event where it repeats, but the times across the days are not the same. I created an event from 10h00 to 16h30 and made it repeat for two days. Now the times need to be adjusted independently for the two days. I could just cancel the repeat and book a new appointment for the second day but the event has a confirmed room booking and with rooms at a premium I worry that someone else may grab the room before I can create the new second day event. Outlook had a way to modify repeating events individually but I'm not seeing anything like that in the Google Calendar web client. So my question is whether there is a way to individually edit repeating events, or failing that, to split the repeating event into individual ones?

• Good reference for Cisco Resilient Ethernet Protocol

  - by Karthik

  I have been trying to understand Cisco's Resilient Ethernet Protocol, but am unable to find a proper source to read from. I checked the Cisco site and also their White Paper on REP. But none of them helped to understand REP clearly. Googling was also of not much help, as all I got was explanation about configuration instructions and not on the protocol itself. Can you guys point me to a good book or site, which explains Resilient Ethernet Protocol in detail? Thanks in advance.

• Custom CSV (.csv) filter for OpenOffice.org or LibreOffice?

  - by anon

  Is it possible to create a some kind of 'custom CSV filter' for OpenOffice.org or LibreOffice spreadsheet program. What I need is to have the program to use predefined CSV settings for loading and saving when I open, let's say file named 'somefile.myext'. Also I would need the loaded data to be placed in a prestyled spreadsheet. In this particular case, I would need the CSV settings to have tab as a field delimiter and no text delimiter at all. Prestyled spreadsheet would contain Blue gray coloring for every odd row (achieved with conditional formatting formula), some font styling and probably some column width definitions.

• What power cord does a WD16001032 hard drive use?

  - by llcf

  I have a Western Digital 160GB My Book USB external hard drive (WD16001032), but I can't find its power cord (or, at least, figure out which one it is in my box of cords). It might be that only one power cord would fit, but I'm a bit cautious since I just tried one of the cords with a router and could smell electronics burning when I used an incorrect one. What voltage/amps are needed for this drive? I can't find specs on Western Digital's site. I'm assuming this is due to it being an older drive.

• PHP $_GET and $_POST are returning empty arrays--trying to paginate SQL data

  - by George88

  I have set up the following: Database class ($db) Pagination class ($paginator) I am attempting to write a basic system to let me administrate pages. I have a page "page_manager.php" in which I include both my database class (database.php) and my pagination class (paginate.php). In my pagination class I have a function which echoes my SQL data. I've come up with a way to echo an HTML < select element with the necessary IDs, which allows me to successfully echo the corresponding results (10 per page), based on the value of the < select element. So, "1" will echo the first 10 results in the database, "2" will echo from 11-20, "3" will echo from 21-30, etc., etc.. I have added an onChange event to the < select element which will copy its value (using "this.value") to a hidden form field. I then submit this form using document.getElementById().submit(); This will then add the $_GET variable to the URL, so the URL becomes ".../?pagenumber_form=X". However, when I try to grab this value back from the URL, the $_GET['pagenumber_form'] is empty. Some code: <span style='font-family: tahoma; font-size: 10pt;'>Page #</span> <select id="page_number_selection" onchange='javascript: document.getElementById("pagenumber_form").value = this.value; document.getElementById("pagenumber").submit();'> <?php for($i = 1; $i <= $this->num_pages; $i++) echo"<option id='" . $i . "'>" . $i . "</option>"; ?> </select> <form name="pagenumber" id="pagenumber" action="" method="get"> <input type="text" name="pagenumber_form" id="pagenumber_form" /> </form> So, I've tried using $_POST as well, but the same thing happens. I want to use $_GET, for a couple of reasons: it's easier to see what is happening with my values and the data I'm using doesn't need to be secure. To recap: the $_GET variable is being added to the URL when I change the < select element, and the corresponding value gets added to the URL as: ".../?pagenumber_form=X", but when I try to use the value in PHP, for example... $page_number = $_GET['pagenumber_form']; ... I get a NULL value. :-( Can anybody help me out please? Thank you. EDIT: I've just made a discovery. If I move my print_r($_GET) to my main index page, then the superglobals are returning as expected. My site structure is like this: index.php - JavaScript buttons use AJAX HTTP requests to include the "responseText" as the .innerHTML of my main < div . The "responseText" is the contents the page itself, in this case page_manager.php, which in turn includes pagination.php. So in other words, my site is built from PHP includes, which doesn't seem to be compatible with HTTP superglobals. Any idea how I can get around this problem? Thank you :-).

• Domain Hosting, DNS/NS Management [closed]

  - by ledy

  What criteria do you have for choosing the right provider for registering a domain? (not hosting, only the domain) So far, I can only see the different pricing and features of the DNS manager but have no idea what I have to pay attention in addition to this. How to know about the quality of the provider's nameserver and could there be differences in speed concerns. Background: The hosting itself incl. webspace, server etc. is separate from the domain and I am not going to book the domain with the same hoster as the webspace/server hoster.

• Send emails in a non-interactive way in OS X

  - by flow

  I am using Mail.app in OS X 10.7. In a text file I have a list with 500 different email addresses, extracted from my address book, each one in a different line. I would like to send some christmas. So I prepared a text template and I would like to send same text in an email to each recipient, just to each one. So I wonder if using some scripting this could be done in a non-interactive way in OS X. In Linux I think this could be done using "mutt".

• Twisted pair cable twists and unwanted signals issue

  - by ziaharipur

  I am confused about one point I have read the following paragraph from the networking book. “the twists in the twisted pair cable are used to avoid the unwanted signals. For example one twist, one wire is closer to the noise source and the other is farther; in the next twist the reverse is true. Twisting makes its probable that both wires are equally affected by the unwanted signal. This means that the receiver which calculate the difference between the two receives no unwanted signal.” Now ok I understood the purpose of twists but I am confused about how receiver will calculate the difference when it will receive the signal?. How unwanted signal will be eliminated ? Another thing that I want to make clear is , I am beginner please provide such an answer that can be understood.

• Do emails from ShoppyBag contain virus or malware ?

  - by Sysadmin Evstar

  I am curious -- when the ShoppyBag virus gets sent to you from a compromised "friend", inside the message is a secret one-pixel IMG unique to your email address --- and when your GMail message pulls up the message and the IMG is loaded from their server and displayed, their server knows you have read the message. At that moment, does it then grab your Gmail address book, the Flash Cookies, and all the Local Shared Objects it can find, i.e. at the instant you READ the message with the ShoppyBag virus, is it already too late? Do you have to Delete it to the Trash , then Delete Forever it , without reading it to be safe?

• Resolution is Being Stupid. Help me?

  - by One Terrorist

  I'm having trouble with a new computer I bought a few days ago. I have come to the conclusion that the resolution of the screen is too small, at the moment it is 1024x768 and I think it should be 1280x960, due to a message given at the resolution tab of the control panel. It states: (!) If your resolution is below 1280x960, some items on the screen may not fit on the screen. The computer is an Asus A54H and runs 64-bit operating system with Windows 7 Home Premium. This link has a screenshot of the screen at the moment, the icons and font are too big and are a little stretched. Thank you in advance!

• What is Slotted and pure aloha?

  - by caspert

  So I am having a really hard time understanding slotted and pure aloha. I have understood CSMA/CD fairly well, but that is it. I have the book: Computer networking - a top down approach, but I find the explanation very cryptic and hard to understand. Wikipedia did not help me. Does anyone have a brief "aloha for dummies" explanation? or perhaps a video tutorial? I think I need something visual. I don't need to be able to create the protocol, I just need a general understanding of it.

• How does a frame retrieve the recipient's MAC address?

  - by Sarmen B.

  I am studying a Network+ book named All-in-one CompTia Network+ by Mike Meyers. In chapter 2 he talks about frames and how he represents them as canisters and the data within the frame contains the recipients mac address, senders mac address, data, and sequence number. What I don't understand is if the sender is sending a file via the network to the recipient, and this frame contains this data, how does the frame know what the recipients MAC address is before sending it? In regards to TCP/IP when it contains the recipients IP address, that's understandable how it retrieves that value. But I don't understand how it can retrieve the MAC address, because if that frame comes from the senders computer, goes into the router and copies itself to each and every computer that exists on the network, how did it have the MAC address to know where to go? Let me know if I'm not making sense.

• Some Domain Clients unable to access certain websites

  - by Shaunie

  I have a small domain around 20 clients with a 2003 R2 SP2 DC. Most of my clients can browse the internet freely and dont have a problem. However a couple are reporting problems accessing certain sites. IE: Hotmail, skyscanner, bbc news They can browse the sites sometimes then other times they get 408\409 errors. other machines in the domain can access these sites. I have cleared out dns cache on these machines modified external dns servers on the DC still to no avail. The main issue is the person not able to access skyscanner uses it several times a day to book flights for employess going on leave or returning to work. both clients are running XP SP3 though one machine is getting change for one running win7 shortly. Any advice greatly appreciated. thanks

• If I use a facade class with generic methods to access the JPA API, how should I provide additional processing for specific types?

  - by Shaun

  Let's say I'm making a fairly simple web application using JAVA EE specs (I've heard this is possible). In this app, I only have about 10 domain/data objects, and these are represented by JPA Entities. Architecturally, I would consider the JPA API to perform the role of a DAO. Of course, I don't want to use the EntityManager directly in my UI (JSF) and I need to manage transactions, so I delegate these tasks to the so-called service layer. More specifically, I would like to be able to handle these tasks in a single DataService class (often also called CrudService) with generic methods. See this article by Adam Bien for an example interface: http://www.adam-bien.com/roller/abien/entry/generic_crud_service_aka_dao My project differs from that article in that I can't use EJBs, so my service classes are essentially just named beans and I handle transactions manually. Regardless, what I want is a single interface for simple CRUD operations on my data objects because having a different class for each data type would lead to a lot of duplicate and/or unnecessary code. Ideally, my views would be able to use a method such as public <T> List<T> findAll(Class<T> type) { ... } to retrieve data. Using JSF, it might look something like this: <h:dataTable value="#{dataService.findAll(data.class)}" var="d"> ... </h:dataTable> Similarly, after validating forms, my controller could submit the data with a method such as: public <T> void add(T entity) { ... } Granted, you'd probably actually want to return something useful to the caller. In any case, this works well if your data can be treated as homogenous in this manner. Alas, it breaks down when you need to perform additional processing on certain objects before passing them on to JPA. For example, let's say I'm dealing with Books and Authors which have a many-to-many relationship. Each Book has a set of IDs referring to its authors, and each Author has a set of IDs referring to their books. Normally, JPA can manage this kind of relationship for you, but in some cases it can't (for example, the google app engine JPA provider doesn't support this). Thus, when I persist a new book for example, I may need to update the corresponding author entities. My question, then, is if there's an elegant way to handle this or if I should reconsider the sanity of my whole design. Here's a couple ways I see of dealing with it: The instanceof operator. I could use this to target certain classes when special processing is needed. Perhaps maintainability suffers and it isn't beautiful code, but if there's only 10 or so domain objects it can't be all that bad... could it? Make a different service for each entity type (ie, BookService and AuthorService). All services would inherit from a generic DataService base class and override methods if special processing is needed. At this point, you could probably also just call them DAOs instead. As always, I appreciate the help. Let me know if any clarifications are needed, as I left out many smaller details.

• Too Much Swapping, even though RAM is 2/3 Empty

  - by indyaah

  I have a VPS with 9GB RAM, 300GB HDD, 3 GB Swap, 7 Cores. The OS is CentOS 5.7 Final. I have postgres9.0 running on my machine, with proper tuning done (at least by book/wiki of PostgreSQL). What happens is most of the times when some complex query run (by complex I mean select with maximum 3 Joins), eventhough 66% of my RAM is unused there is ~99% swapping is happening. Plus it screws up my disk IO which is most of the time reaching ~100% and slows down everything else. (I tend to believe something's wrong with my disk.) I dont understand the reason of this much of swapping happening. Is it because of context switching?? Most of the time my processors are idle, while the IO wait goes upto 30% during pick times. Would appreciate if some can shed some light on it. Thanks.

• Color in Cygwin terminal

  - by ForbesLindesay

  I've installed cygwin because I'm a bit fed up with the Windows terminal not being great. The only problem I'm having is the lack of colours. You can see the problem in the following 2 screenshots that display the same command: All I want is something which has a nice font, resizes properly (including proper behaviour when maximised) and support for colours. Ideally I'd like tabs too. This seems like a silly reason to end up buying a mac, so I'm hoping I can get all these things on windows somehow.
