• 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.

• 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?

• Can I save my app's state at close time in iPhone OS?

  - by Steve

  I have an app that functions much like an ebook. I have a bunch of textual information in various languages that is accessible through a number of drill down methods. When a user wants to get into where they were reading last, they currently have to navigate through the section and chapter menus to get back to where they were. An ideal solution for this would be to setup a bookmark system, which I am considering. But if I remember correctly, when iPhone OS 4 was announced, they seemed to make a big deal of the added ability to save the state of an app. Does that mean that someone using my reader app would be able to just exit right out, do whatever, and then when they came back in, it would be the reading screen just as they left it? I don't know much about how to setup a bookmarking system, I suppose it would be worth investigating, but I would probably want to just hold off for iPhone OS 4 if that is indeed what it will be capable of doing. Any thoughts or insights would be appreciated!!

• 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.

• WebUIView is very slow

  - by Shamil

  Hello, I'm building a custom RSS reader app with incorporated feed link view (UIWebView). Using the following code, when the view, containing WebUIView is loaded, it takes about 6 seconds before anything is outputted to the user: -(void)viewDidLoad{ [super viewDidLoad]; NSString *urlString = [[[self appDelegate] currentlySelectedBlogItem]linkUrl]; NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [_webview loadRequest:requestObj]; [_webview setScalesPageToFit:YES]; } Any ideas why UIWebView is being so slow? I've checked the URL input, it's clean and what I'd expect it to be. I'm building for iOS 3.0 as base deployment target.

• How to save multiple UIImage to a file iPad

  - by aron

  I have a PDF reader that displays pages of the document. What I want to do is allow the user to draw over the PDF in a transparent view. Then I want to save the drawing (UIImage) to disk. If at all possible, I don't want to have the documents folder filled with files like documentName_page01.png, documentName_page02.png for every page that is drawn over. However, I can't figure out how to store these UIImages into a single file without it becoming unwieldy and memory intensive. Any ideas appreciated.

• Will my app get rejected because of this ???

  - by A for Alpha

  hi guys... i am developing a ebook reader app for iPad and i am facing a issue related to the design aspects of the bookshelf. I am posting a sample photo of my bookshelf here. I want the book shelf to have a horizontal navigation similar to that of the iBooks. Will this come under violation of Apple's HIG?? Will they consider this design to be a imitation of their iBooks design and reject it?? I'm worried...

• Table character encoding - exception in application

  - by zgnilec

  I have a code: CREATE TABLE IF NOT EXISTS Person ( name varchar(24) ... ) CHARACTER SET utf8 COLLATE utf8_polish_ci; This works OK in my application, but I read if someone put in name field a string that contains character wchich code is greater than 127, database will use 2 bytes (or more) to store this character. So i think, i will change character set to utf16: CHARACTER SET utf16 COLLATE utf16_polish_ci; But now when I run my application, exception apears: KeyNotFoundException. It apears exactly at these instructions: MySqlCommand komenda = baza.Polaczenie.CreateCommand (); komenda.CommandText = zapytanie; MySqlDataReader dr = komenda.ExecuteReader (); // HERE, at execute reader method if (dr.Read ()) ... 1) Anyone had similar problem? 2) Any idea how to use always 2 bytes/char in database field?

• No optimization causes wrong search result

  - by KailZhang

  I just took over our solr/lucene stuff from my ex-colleague. But there is a weird bug. If there is no optimization after dataimport, actually if there are multiple segment files, the search result then will be wrong. We are using a customized solr searchComponent. As far as I know about lucene, optimization is only optimization which could improve the speed of indexing and should not affect search result. I doubt this may be related to multithreading or unclosed searcher/reader or something. Anybody can help? Thank you.

• How to decode U.P.S. Information from UPS MaxiCode Barcode?

  - by user46482

  I recently purchased a 2D Barcode reader. When scanning a U.P.S. barcode, I get about half of the information I want, and about half of it looks to be encrypted in some way. I have heard there is a UPS DLL. Example - Everything in bold seems to be encrypted, while the non-bold text contains valuable, legitimate data. [)01961163522424800031Z50978063UPSN12312307G:%"6*AH537&M9&QXP2E:)16(E&539R'64O In other words, this text seems OK - and I can parse the information [)01961163522424800031Z50978063UPSN123123 ... While, this data seems to be encrypted ... 07G:%"6*AH537&M9&QXP2E:)16(E&539R'64O Any Ideas???

• How do I write a Java text file viewer for big log files

  - by Hannes de Jager

  I am working on a software product with an integrated log file viewer. Problem is, its slow and unstable for really large files because it reads the whole file into memory when you view a log file. I'm wanting to write a new log file viewer that addresses this problem. What are the best practices for writing viewers for large text files? How does editors like notepad++ and VIM acomplish this? I was thinking of using a buffered Bi-directional text stream reader together with Java's TableModel. Am I thinking along the right lines and are such stream implementations available for Java?

• 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.

• Would Python's Twisted library be the best case for an observer type pattern?

  - by beagleguy

  hi all, I'm developing a system where a queue will be filled with millions of items I need a process that reads items from the queue constantly and then sends those items out to registered clients. I'm thinking about using twisted for this, having the queue reader be a twisted server listening on a tcp port then clients can connect on that port and when an item is pulled from the queue the server writes it out to all the clients. Does that sound like something that twisted would be ideal for? Does anyone know of any sample code out there that may do something similar? thanks

• problem reading a csv file in python

  - by Hossein

  Hi, I am trying to read a very simple but somehow large(800Mb) csv file using the csv library in python. The delimiter is a single tab and each line consists of some numbers. Each line is a record, and I have 20681 rows in my file. I had some problems during my calculations using this file,it always stops at a certain row. I got suspicious about the number of rows in the file.I used the code below to count the number of row in this file: tfdf_Reader = csv.reader(open('v2-host_tfdf_en.txt'),delimiter=' ') c = 0 for row in tfdf_Reader: c = c + 1 print c To my surprise c is printed with the value of 61722!!! Why is this happening? What am I doing wrong?

• RSS feed per tag

  - by niaher

  Hi. Suppose stackoverflow.com wanted to have an RSS feed per each tag. They would probably have requests like stackoverflow.com/rss?tag=aspnet to return appropriate RSS feeds. This is the easy part. Now when the user requested stackoverflow.com/rss?tag=aspnet he would see some XML. Instead it would be better to show a page where user can choose which RSS reader he wants to subscribe with (just like feedburner.com). My question is: is there any ready-made code (html+javascript) that I can copy-paste to create such a subscription page? Basically I want to copy feedburner.com's subscription page onto my own site. PS - I would be happy using feedburner.com, but it would require me to create a feed for each tag manually, which is impractical.

• Nice RSSFeed Control

  - by Kovu

  Hi, I develope an application in C#.Net 2.0, Windows. The App has a RSS Feed Reader for specific sites (to collect the biggest news).

But my problem is the design, I tried a lot, how to display easy, quick and nice, but it sucks like hell, I tried nerly every control in the toolbox and fill it with the RSS Feeds and it looks ugly. So knows anybody a control to display RSS feeds nicly? I know its an copy, but no one answers there.

• 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.

• Any good class diagram editors out there for Java (not UML)

  - by user85116

  I'm looking for an editor that can create class diagrams, similar to the typical UML class diagram, but specifically for java (so using java terminology; instead of terms like "generalization, realization etc", we use the java equivalents "interface, abstract class, extends etc"). I've looked into UML several times, but each time I've been turned off by the shear amount of "stuff" that comes with UML. I just want to be able to model my java classes quickly and intuitively, without getting bogged down by all the cruft that comes with UML. Preferably, it would come with a source reader that can keep the diagram up to date, and with a few nice features like "show only public methods in this class" etc. As well, it would automatically "know" about the classes in the standard java library, and possibly even be able to read classes from jars. Performance is also a big thing for me, I don't like having to wait 2 seconds for a popup menu to appear, or watch the diagram jerk crazily while resizing an element in the model. What do you think, am I asking too much?

• 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.

  I dont have any experience for web services. please give me some suggestion about the task below. the task is: users will send a txt file (size should less than 20K ) from a .NET application, I need to write a web services which runs by jboss 5.x to read this file and edit this file and send the file back to .NET UI to display the edited version. question is that if the txt file is just test string or binary string, are there any restriction of the string length? if it's binary string, can I need to use BinaryReader class to read it? or not need special reader to read it? (this could be a dumn question :P) what if the .NET application can save the file on either the .NET application server or some shared server location, send a download URL to web serivces, can web services download it and read it? JBoss will be run on Linux sever. After edit the file, how do I send it back? Thanks for your help!

• 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?

• Access uploaded file in JSON encoded data

  - by okello

  I've encoded my form data into JSON. This has been achieved by the following ExtJS store configuration: Ext.define('XXX.store.Registration', { extend: 'Ext.data.Store', model: 'XXX.model.Registration', autoLoad: true, pageSize: 15, autoLoad: { start: 0, limit: 15 }, proxy: { type: 'ajax', api: { create: './server/registration/create.php', read: './server/registration/get.php', update: './server/registration/update.php', destroy: './server/registration/destroy.php' }, reader: { type: 'json', root: 'registrations', successProperty: 'success' }, writer: { type: 'json', writeAllFields: true, encode: true, root: 'registrations' } } }); My server side code has been implemented in PHP. I can access the encoded form fields by using the field name as a key, as exemplified below: $reg = $_REQUEST['registrations']; $data = json_decode(stripslashes($reg)); $registerNum = $data->registerNum; $folioNum = $data->folioNum; One of the fields in my form is a fileuploadfield. How can I access the uploaded file from the uploaded JSON. Any assistance will be highly appreciated.

• 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.

  - by ferrari fan

  Hi, If I want to have a question with a "Yes/No" radio button. How do I need to mark up the code so that a screen reader reads the question associated with the "yes/no" selection instead of just reading the "Yes" and "No" labels when the radio buttons are selected? <span>Did you understand this? (choose one) </span> <label> <input type="radio" id="yes_no" name="yes_no" value="Yes" /> Yes </label> <label> <input type="radio" id="yes_no" name="yes_no" value="No" /> No </label> Thanks
