  • Hack Your Kindle for Easy Font Customization

    - by Jason Fitzpatrick
    The font options included with the Kindle are certainly serviceable, but why limit yourself? Today we’ll show you how to easily swap out the font files on your Kindle for a completely customized reading experience. Why customize the font? Why not! It’s your ebook reader and if you want the font to be crisper, thicker, look like it belongs on Star Trek, or pack more words per line, there’s no need to let Amazon’s design decisions stand in your way. Today we’re going to show you how you can install new fonts on your Amazon Kindle with free tools and about 20 minutes of tinkering (most of which will be spent waiting for the Kindle to reboot and rebuild the fonts).

  • Where's the source code?

    - by Kyle Burns
    I've been contacted by several people through this blog asking about the missing source code for the "Beginning Windows 8 Application Development - XAML Edition" book (the book is available at http://www.amazon.com/gp/product/1430245662/http://www.amazon.com/gp/product/1430245662/) and wanted to share this with others who may have come to this blog looking for it but may not have communicated with me.  The publisher (Apress) does know that the source code is not posted on the book's product page and will be correcting it.  Apress is located in New York City and things were slowed down a little bit last week due to the storm, but I've been assured they will be correcting the product page as soon as they can.  Thanks to everyone who has bought the book and I especially appreciate your patience.

  • A Change of Seasons...

    - by James Michael Hare
    As some of you already know, today is my last day at Scottrade. It has been a great place to work and I'll miss all the relationships I've formed over the last 5 years immensely! Starting Monday, I will be taking a new position at Amazon.com in Seattle. It should be an exciting new adventure and I look forward to sharing more about my experiences in the days to come! I do intend to continue blogging (after the move settles down) about C# as I'm able, and may mix in some Java as well as I rekindle (Amazon? Kindle? Get it? Okay, that was lame, I know...) my knowledge of the language for my new job responsibilities. I'll miss all the relationships I've developed with the .NET community in St. Louis and the surrounding area, and hope to come back sometime to participate in future Days of .NET conferences, if able! Stay tuned for more updates!

  • Kindle for PC via Wine

    - by Mollikins
    I've been checking out all the free books on Amazon and I really want to get the Kindle PC program running on my computer so I can download, read, and manage my e-books. I realize that Calibre can be used to manage e-books and I do have that downloaded. However, Amazon won't let me download ebooks unless my PC is registered in their little Kindle program and I'd like to just keep things streamlined by playing by the rules for once. I've viewed so many tutorials and advice for setting it up. I have Wine, I have Kindle for PC, I set it to Win98, all of that. However, when I try to open KindlePC from the Wine menu or from the desktop icon, nothing happens. No error messages, nothing. I don't know what might be wrong. Please let me know if you have any experience with this and any suggestions!

  • Tricky mod_rewrite challenge

    - by And Finally
    I list about 9,000 records on my little site. At the moment I'm showing them with a dynamic page, like http://domain.com/records.php?id=019031 But I'd like to start using meaningful URLs like this one on Amazon http://www.amazon.co.uk/Library-Mythology-Oxford-Worlds-Classics/dp/0199536325 where the title string on the root level gets ignored and requests are redirected to the records.php page, which accepts the ID as usual. Does anybody know how I could achieve that with mod_rewrite? I'm wondering how I'd deal with requests to my other root-level pages, like http://domain.com/contact.php, that I don't want to redirect to the records page.

  • Help assigning product id for e-commerce site? [closed]

    - by Stanford Sequeira
    I am starting an e-commerce marketplace. I am new to e-commerce, but I am taking it up as a challenge. I will have multiple vendors on my site and they will upload their products through CSV files for bulk upload. However there will be certain popular products already listed in the database, they can add those to their listing (like Amazon for 3rd party sellers). I have no idea how to assign product codes for every product, can you help me out? I'm talking about something like Amazon's ASIN number. Or may be is it possible to let vendors assign their own numbers? How does that work?

  • Distributed development staff needing a common IP range

    - by bakasan
    I work on a development staff that is geographically distributed, mostly all throughout the state of CA, but several key members also must travel frequently. We rely quite heavily on a 3rd party provider API for a great deal of our subsystems (can't get into who it is or what they do). The 3rd party however is quite stringent on network access and have no notion of a development sandbox. Access is restricted to 2, 3 IP numbers and that's about it. Once we account for our production servers, that leaves us with an IP or two to spare for our dev team--which is still problematic as people's home IP changes, people travel, we have more than 2 devs, etc. Wide IP blocks are not permitted by the 3rd party. Nor will they allow dynamic DNS type services. There is no simple console to swap IPs on the fly either (e.g. if a dev's IP at home changes or they are on the road). As none of us are deep network experts, I'm wondering what our viable options are? Are there such things as 3rd party hosts to VPNs? Generally I think of a VPN as a mechanism to gain access to a home office, but the notion would be a 3rd party VPN that we'd all connect to and we'd register this as an IP origin w/ our 3rd party. We've considered using Amazon EC2 to effectively host a dev environment for each dev and using that to connect. Amazon only gives you so many static IPs however (I believe 5?) so this would only be a stop gap solution until our team size out strips our IP count at Amazon. Those were the only viable thoughts that I had, but again, I'm far from a networking guy. Tried searching for similar threads, but I'm not even sure I know the right vernacular to look around for.

  • Gmail: Received an email intended for another person. [closed]

    - by jonescb
    I'm not really sure how email routing works, but someone ordered something on Amazon and I received the email instead of them. Or maybe we both got it, I don't know. The order doesn't show up in my account, so I'm certain I wasn't charged for it, but I shouldn't be getting other peoples' emails. We'll say that my email is [email protected], and somebody who's email is [email protected] places an order on Amazon. The confirmation email is sent to me at [email protected]. I checked the email header, and it did say To: [email protected] which is not my email address. At first I thought that Google ignores periods in email addresses, but I tested the account setup and it doesn't give any error when you put a period in the address. I didn't create the account; I just used the "check availability" function and the address I chose with a period was fine. Maybe someone with knowledge about how Email works could tell me why this happened. Is this a bug in the way Amazon sends emails? Or is it a bug in how Google receives them? Who should I report this issue to?

    Hi, I am very interested in learning windows shell programming. So...I searched for books on the amazon.com. I see that books on the amazon.com are out of date. Most of books are published before 2005. I googled about it and found many tips and tricks, but not step by step guide. Where do I get started?

  • How can I await the first completed async task of a list in .Net?

    - by Eyal
    My input is a long list of files located on an Amazon S3 server. I'd like to download the metadata of the files, compute the hashes of the local files, and compare the metadata hash with the local files' hash. Currently, I use a loop to start all the metadata downloads asynchronously, then as each completes, compute MD5 on the local file if needed and compare. Here's the code (just the relevant lines): Dim s3client As New AmazonS3Client(KeyId.Text, keySecret.Text) Dim responseTasks As New List(Of System.Tuple(Of ListViewItem, Task(Of GetObjectMetadataResponse))) For Each lvi As ListViewItem In lvStatus.Items Dim gomr As New Amazon.S3.Model.GetObjectMetadataRequest gomr.BucketName = S3FileDialog.GetBucketName(lvi.SubItems(2).Text) gomr.Key = S3FileDialog.GetPrefix(lvi.SubItems(2).Text) responseTasks.Add(New System.Tuple(Of ListViewItem, Task(Of GetObjectMetadataResponse))(lvi, s3client.GetObjectMetadataAsync(gomr))) Next For Each t As System.Tuple(Of ListViewItem, Task(Of GetObjectMetadataResponse)) In responseTasks Dim response As GetObjectMetadataResponse = Await t.Item2 If response.ETag.Trim(""""c) = MD5CalcFile(lvi.SubItems(1).Text) Then lvi.SubItems(3).Text = "Match" UpdateLvi(lvi) End If Next I've got two problems: I'm awaiting the reponses in the order that I made them. I'd rather process them in the order that they complete so that I get them faster. The MD5 calculation is long and synchronous. I tried making it async but the process locked up. I think that the MD5 task was added to the end of .Net's task list and it didn't get to run until all the downloads completed. Ideally, I process the response as they arrive, not in order, and the MD5 is asynchronous but gets a chance to run. Edit: Incorporating WhenAll, it looks like this now: Dim s3client As New Amazon.S3.AmazonS3Client(KeyId.Text, keySecret.Text) Dim responseTasks As New Dictionary(Of Task(Of GetObjectMetadataResponse), ListViewItem) For Each lvi As ListViewItem In lvStatus.Items Dim gomr As New Amazon.S3.Model.GetObjectMetadataRequest gomr.BucketName = S3FileDialog.GetBucketName(lvi.SubItems(2).Text) gomr.Key = S3FileDialog.GetPrefix(lvi.SubItems(2).Text) responseTasks.Add(s3client.GetObjectMetadataAsync(gomr), lvi) Next Dim startTime As DateTimeOffset = DateTimeOffset.Now Do While responseTasks.Count > 0 Dim currentTask As Task(Of GetObjectMetadataResponse) = Await Task.WhenAny(responseTasks.Keys) Dim response As GetObjectMetadataResponse = Await currentTask If response.ETag.Trim(""""c) = MD5CalcFile(lvi.SubItems(1).Text) Then lvi.SubItems(3).Text = "Match" UpdateLvi(lvi) End If Loop MsgBox((DateTimeOffset.Now - startTime).ToString) The UI locks up momentarily whenever MDSCalcFile is done. The whole loop takes about 45s and the first file's MD5 result happens within 1s of starting. If I change the line to: If response.ETag.Trim(""""c) = Await Task.Run(Function () MD5CalcFile(lvi.SubItems(1).Text)) Then The UI doesn't lock up when MD5CalcFile is done. The whole loop takes about 75s, up from 45s, and the first file's MD5 result happens after 40s of waiting.

  • How to extend a large website to an iPhone app?

    - by xoail
    I am trying to create an iPhone app for a large website (as big as amazon.com) and it involves using cookies and what not to get authenticated via the Apache intercepter and access the web services exposed by the main website. For that I am looking for strategies to go about developing it. I am new to iPhone development and I am mostly looking for some architectural guidance. Does anyone know how services like eBay and Amazon work seamlessly across the website and iPhone app?

  • APK Assets not loaded on Kindle Fire HD

    - by Bastl
    I have developed an App for the Amazon Kindle Fire HD. While distributing I got a report from amazon that its not running on almost all Kindle devices and a blackscreen is displayed. They send me a logcat log file and I found out that it's not possible to load some assets directly from APK file (accessing via C++ and zlib). Everything is running fine if I start it via Eclipse. Any idea whats going wrong? Thanks!

  • How do I make menus like these?

    - by Doug
    So I'm looking at slickdeals.net and amazon.com, and I found something very intriguing. It's basic for most of you guys out there, but it's new to me. For slickdeals.net, when you click login, a login box pops up like so. Also for Amazon.com, when you hover over the left navigational menus, a new menu pops up! I think it's JavaScript, but how does this work? How can I do something like that?

  • How can I tell Firefox to ignore unprintable characters?

    - by BrianH
    Edit: Summary Apparently the intended character to display in this case is an "en-dash". This page has a table half way down that shows that for the &ndash;, some software will convert the correct hex code of 2013 to 0096. (look at the first row in the table). This answer on Stackoverflow explains that somehow this is a mixup between Windows-1252 and UTF-8 This blog article enforces this: Character 150 (0x96) is the unicode character "START OF GUARDED AREA" in the non-displayed C1 control character range, but in the Windows-1252 encoding it's mapped to to the displayable character 0x2013 "en-dash" (a short dash). Others have struggled with this when producing content, as this answer on Stackoverflow shows how to replace 0x0096 with 0x2013. Google must realize this, because as stated in my original question below, Google's cached version of the Amazon page has &ndash; so it seems they are automatically correcting these mistakes on pages they cache. I have tried setting my encoding to Windows-1252 but that does not help. So now I guess my question is, how can I tell Firefox to ignore unprintable characters like these? Original content below: (Firefox 3.6.13 on Windows XP) Every once in a while I notice an odd character on certain web pages when browsing the web. It is a outline of a box with a 4-digit number inside. And example of a page that has these characters is: http://aws.amazon.com/ec2/#highlights After each section heading (Elastic, Completely Controlled, ...) I see a box with the number "0096" inside. I looked at the cached version on Google, and google has &ndash; in it's place, so I'm guessing I should be seeing a dash there instead of the box with the numbers in it. I have tried changing the character encoding in Firefox but haven't been able to find one that shows these characters correctly. Is there a way to allow Firefox to view these characters? Thanks in advance! Edit - adding a screen shot of the "special" characters: Edit #2 - tried in Ubuntu - new screenshots I logged into my Ubuntu desktop and browsed to the amazon page in Chrome and Firefox. Chrome completely ignores character, even if I inspect or view page source. Firefox in Unbutu displays the character exactly like Firefox on my Windows XP box. I copied the character and played around with it at the command line - here is a screenshot of the results: It looks like I can paste the character into this post as well: `` It is definitely not isolated to Windows XP. I tried setting the character encoding for my terminal to Windows 1252 (from Dennis' comment below), but then it just displays this character as a question mark. I pulled the webpage down with wget and with curl, and both outputs show this characters as: <96> It makes me wonder if this character renders correctly for anyone? It appears webkit just ignores it, my IE6 ignores it, Firefox displays the box with the numbers in it. I would have to imagine the design team at Amazon can see it correctly? It's not a huge deal to get these characters displaying correctly, but it would be nice to know if there is a solution to this.

  • Rewriting Apache URLs to use only paths and set response headers

    - by jabley
    I have apache httpd in front of an application running in Tomcat. The application exposes URLs of the form: /path/to/images?id={an-image-id} The entities returned by such URLs are images (even though URIs are opaque, I find human-friendly ones are easier to work with!). The application does not set caching directives on the image response, so I've added that via Apache. # LocationMatch to set caching directives on image responses <LocationMatch "^/path/to/images$"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> Note that I can't use ExpiresByType since not all images served by the app have versioned URIs. I know that ones served by the /path/to/images resource handler are versioned URIs though, which don't perform any sort of content negotiation, and thus are ripe for Far Future Expires management. This is working well for us. Now a requirement has come up to put something else in front of the app (in this case, Amazon CloudFront) to further distribute and cache some of the content. Amazon CloudFront will not pass query string parameters through to my origin server. I thought I would be able to work around this, by changing my apache config appropriately: # Rewrite to map new Amazon CloudFront friendly URIs to the application resources RewriteRule ^/new/path/to/images/([0-9]+) /path/to/images?id=$1 [PT] # LocationMatch to set caching directives on image responses <LocationMatch "^/path/to/images$"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> This works fine in terms of serving the content, but there are no longer caching directives with the response. I've tried playing around with [PT], [P] for the RewriteRule, and adding a new LocationMatch directive: # Rewrite to map new Amazon CloudFront friendly URIs to the application resources # /new/path/to/images/12345 -> /path/to/images?id=12345 RewriteRule ^/new/path/to/images/([0-9]+) /path/to/images?id=$1 [PT] # LocationMatch to set caching directives on image responses <LocationMatch "^/path/to/images$"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> <LocationMatch "^/new/path/to/images/"> # Can't have Set-Cookie on response, otherwise the downstream caching proxy # won't cache! Header unset Set-Cookie # Mark the response as cacheable. Header append Cache-Control "max-age=8640000" </LocationMatch> Unfortunately, I'm still unable to get the Cache-Control header added to the response with the new URL format. Please point out what I'm missing to get /new/path/to/images/12345 returning a 200 response with a Cache-Control: max-age=8640000 header. Pointers as to how to debug apache like this would be appreciated as well!

  • Stop Zabbix notification for nodes under zabbix-proxy when proxy service is down

  • Having many subdomains with SSL--best practices?

    - by jnunn
    I have a site that has many subdomains (one for each client). The content for each subdomain will be different, pulling different data, different layouts etc, so I don't think I can just alias one directory to many different sub domains. My question is, what's the best practice for doing this? Each subdomain will need SSL. My setup is Amazon EC2 (ubuntu) Wildcard SSL for my domain (*.mydomain.com) Apache 2 PHP (LAMP) Currently, I'm just creating a new entry into "/etc/hosts" and an appropriate spot in the web root (ie /var/www/abc.mydomain.com, /var/www/def.mydomain.com, etc). I've just discovered that I'll need a unique IP for each subdomain, and that's tricky with EC2 as they limit you to the number you can have (unless you jump through some hoops). Right now I have about 10 subdomains, which is manageable, but theoretically I could have thousands. Am I doing it the only way possible or is there a better way I should investigate?

  • Configuring vsftpd with nginx on ubuntu

    - by arby
    I have vsftpd installed on Ubuntu 12.04LTS along with nginx, php, and sql on an Amazon ec2 instance. The web server is good to go, but I'm having trouble connecting to the FTP server. I'm not quite sure how to set the privileges or what configuration options I might be missing. By default, the location of the web root is at /usr/share/nginx/www and it is owned by root:root. The web server runs as user www-data in the group www-data. I've opened port 21 and set the passive ports in the ec2 backend and ufw firewall. In vsftpd.conf, I have: ... anonymous_enable=NO local_enable=YES local_umask=0027 chroot_local_user=YES pasv_enable=YES pas_max_port=12100 pasv_min_port=12000 port_enable=YES ... Now, I'm unsure how to create the FTP user that when I login, displays my web directory with write access. I've tried it a few different ways, but I keep running into errors (either no connection, no write access, or very slow timeouts.)

  • Cloud services, Public IPs and SIP

    - by Guido N
    I'm trying to run a custom SIP software (which uses JAIN SIP 1.2) on a cloud box. What I'd really like is to have a real public IP aka which is listed by "ifconfig -a" command. This is because atm I don't want to write additional SIP code / add a SIP proxy in order to manage private IP addresses / address translation. I gave Amazon EC2 a go, but as reported here http://stackoverflow.com/questions/10013549/sip-and-ec2-elastic-ips it's not fit for purpose (they do a 1:1 NAT translation between the private IP of the box and its Elastic IP). Does anyone know of a cloud service that provides real static public IP addresses?
