  • How do digital certificates prove the identity of a device?

    - by StackedCrooked
    I understand how the relation between issuer and subject certificates enables verification of the subject's authenticity. If I connect to a networked device, and it sends me its certificate to identify itself, then I can verify that it was issued by a trusted party and that it has not been tampered with in any way. However, suppose I simply upload this certificate onto another device. Then what prevents me from having this device identify itself with the copied certificate?

  • Anatomy of a .NET Assembly - Custom attribute encoding

    - by Simon Cooper
    In my previous post, I covered how field, method, and other types of signatures are encoded in a .NET assembly. Custom attribute signatures differ quite a bit from these, which consequently affects attribute specifications in C#. Custom attribute specifications In C#, you can apply a custom attribute to a type or type member, specifying a constructor as well as the values of fields or properties on the attribute type: public class ExampleAttribute : Attribute { public ExampleAttribute(int ctorArg1, string ctorArg2) { ... } public Type ExampleType { get; set; } } [Example(5, "6", ExampleType = typeof(string))] public class C { ... } How does this specification actually get encoded and stored in an assembly? Specification blob values Custom attribute specification signatures use the same building blocks as other types of signatures; the ELEMENT_TYPE structure. However, they significantly differ from other types of signatures, in that the actual parameter values need to be stored along with type information. There are two types of specification arguments in a signature blob; fixed args and named args. Fixed args are the arguments to the attribute type constructor, named arguments are specified after the constructor arguments to provide a value to a field or property on the constructed attribute type (PropertyName = propValue) Values in an attribute blob are limited to one of the basic types (one of the number types, character, or boolean), a reference to a type, an enum (which, in .NET, has to use one of the integer types as a base representation), or arrays of any of those. Enums and the basic types are easy to store in a blob - you simply store the binary representation. Strings are stored starting with a compressed integer indicating the length of the string, followed by the UTF8 characters. Array values start with an integer indicating the number of elements in the array, then the item values concatentated together. Rather than using a coded token, Type values are stored using a string representing the type name and fully qualified assembly name (for example, MyNs.MyType, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0123456789abcdef). If the type is in the current assembly or mscorlib then just the type name can be used. This is probably done to prevent direct references between assemblies solely because of attribute specification arguments; assemblies can be loaded in the reflection-only context and attribute arguments still processed, without loading the entire assembly. Fixed and named arguments Each entry in the CustomAttribute metadata table contains a reference to the object the attribute is applied to, the attribute constructor, and the specification blob. The number and type of arguments to the constructor (the fixed args) can be worked out by the method signature referenced by the attribute constructor, and so the fixed args can simply be concatenated together in the blob without any extra type information. Named args are different. These specify the value to assign to a field or property once the attribute type has been constructed. In the CLR, fields and properties can be overloaded just on their type; different fields and properties can have the same name. Therefore, to uniquely identify a field or property you need: Whether it's a field or property (indicated using byte values 0x53 and 0x54, respectively) The field or property type The field or property name After the fixed arg values is a 2-byte number specifying the number of named args in the blob. Each named argument has the above information concatenated together, mostly using the basic ELEMENT_TYPE values, in the same way as a method or field signature. A Type argument is represented using the byte 0x50, and an enum argument is represented using the byte 0x55 followed by a string specifying the name and assembly of the enum type. The named argument property information is followed by the argument value, using the same encoding as fixed args. Boxed objects This would be all very well, were it not for object and object[]. Arguments and properties of type object allow a value of any allowed argument type to be specified. As a result, more information needs to be specified in the blob to interpret the argument bytes as the correct type. So, the argument value is simple prepended with the type of the value by specifying the ELEMENT_TYPE or name of the enum the value represents. For named arguments, a field or property of type object is represented using the byte 0x51, with the actual type specified in the argument value. Some examples... All property signatures start with the 2-byte value 0x0001. Similar to my previous post in the series, names in capitals correspond to a particular byte value in the ELEMENT_TYPE structure. For strings, I'll simply give the string value, rather than the length and UTF8 encoding in the actual blob. I'll be using the following enum and attribute types to demonstrate specification encodings: class AttrAttribute : Attribute { public AttrAttribute() {} public AttrAttribute(Type[] tArray) {} public AttrAttribute(object o) {} public AttrAttribute(MyEnum e) {} public AttrAttribute(ushort x, int y) {} public AttrAttribute(string str, Type type1, Type type2) {} public int Prop1 { get; set; } public object Prop2 { get; set; } public object[] ObjectArray; } enum MyEnum : int { Val1 = 1, Val2 = 2 } Now, some examples: Here, the the specification binds to the (ushort, int) attribute constructor, with fixed args only. The specification blob starts off with a prolog, followed by the two constructor arguments, then the number of named arguments (zero): [Attr(42, 84)] 0x0001 0x002a 0x00000054 0x0000 An example of string and type encoding: [Attr("MyString", typeof(Array), typeof(System.Windows.Forms.Form))] 0x0001 "MyString" "System.Array" "System.Windows.Forms.Form, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" 0x0000 As you can see, the full assembly specification of a type is only needed if the type isn't in the current assembly or mscorlib. Note, however, that the C# compiler currently chooses to fully-qualify mscorlib types anyway. An object argument (this binds to the object attribute constructor), and two named arguments (a null string is represented by 0xff and the empty string by 0x00) [Attr((ushort)40, Prop1 = 12, Prop2 = "")] 0x0001 U2 0x0028 0x0002 0x54 I4 "Prop1" 0x0000000c 0x54 0x51 "Prop2" STRING 0x00 Right, more complicated now. A type array as a fixed argument: [Attr(new[] { typeof(string), typeof(object) })] 0x0001 0x00000002 // the number of elements "System.String" "System.Object" 0x0000 An enum value, which is simply represented using the underlying value. The CLR works out that it's an enum using information in the attribute constructor signature: [Attr(MyEnum.Val1)] 0x0001 0x00000001 0x0000 And finally, a null array, and an object array as a named argument: [Attr((Type[])null, ObjectArray = new object[] { (byte)2, typeof(decimal), null, MyEnum.Val2 })] 0x0001 0xffffffff 0x0001 0x53 SZARRAY 0x51 "ObjectArray" 0x00000004 U1 0x02 0x50 "System.Decimal" STRING 0xff 0x55 "MyEnum" 0x00000002 As you'll notice, a null object is encoded as a null string value, and a null array is represented using a length of -1 (0xffffffff). How does this affect C#? So, we can now explain why the limits on attribute arguments are so strict in C#. Attribute specification blobs are limited to basic numbers, enums, types, and arrays. As you can see, this is because the raw CLR encoding can only accommodate those types. Special byte patterns have to be used to indicate object, string, Type, or enum values in named arguments; you can't specify an arbitary object type, as there isn't a generalised way of encoding the resulting value in the specification blob. In particular, decimal values can't be encoded, as it isn't a 'built-in' CLR type that has a native representation (you'll notice that decimal constants in C# programs are compiled as several integer arguments to DecimalConstantAttribute). Jagged arrays also aren't natively supported, although you can get around it by using an array as a value to an object argument: [Attr(new object[] { new object[] { new Type[] { typeof(string) } }, 42 })] Finally... Phew! That was a bit longer than I thought it would be. Custom attribute encodings are complicated! Hopefully this series has been an informative look at what exactly goes on inside a .NET assembly. In the next blog posts, I'll be carrying on with the 'Inside Red Gate' series.

  • How to Modify a Signature for Use in Plain Text Emails in Outlook 2013

    - by Lori Kaufman
    If you’ve created a signature with an image, links, text formatting, or special characters, the signature will not look the same in plain text formatted emails as it does in HTML format. As the name suggests, Plain Text does not support any type of formatting. For example, if you include an image in your signature, as shown below, the plain text version will be blank. Active links in HTML signatures will be converted to just the text of the link in plain text emails. The How-To Geek link in the image below will become simply How-To Geek and will look like the rest of the text in the signature. The same thing is true in the following example. The active links are stripped from the text. The picture of the envelope that was inserted using the Wingdings font will only display as the plain text character associated with it. There are times you may need to send email in Plain Text format, but still include your signature. You can edit the plain text version of your signature to make it look good in plain text emails by manually editing the text file. To do this, click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. In the Compose messages section, press and hold the Ctrl key and click the Signatures button. This opens the Signatures folder containing the files used to insert signatures into emails. The .txt file version of each signature is used when inserting a signature into a plain text email. Double-click on a .txt file for the signature you want to edit to open it in Notepad, or your default text editor. Notice that the links on “How-To Geek” and “Email me” are gone and the envelope typed using the Wingdings font was converted to an “H.” Edit the text file to remove extra characters, replace images, and provide full web and email links. Save the text file. Create a new mail message and select the edited signature, if it’s not the default signature for the current email account. To convert the email to plain text, click the Format Text tab and click Plain Text in the Format section. The Microsoft Outlook Compatibility Checker displays telling you that Formatted text will become plain text. Click Continue. The HTML version of your signature is converted to the plain text version. NOTE: You should make a backup of the .txt signature file you edited, as this file will change again when you change your signature in the Signature Editor.

  • WinQual: Why would WER not accept code-signing certificates?

    - by Ian Boyd
    In 2005 i tried to establish a WinQual account with Microsoft, so i could pick up our (if any) crash dump files submitted automatically through Windows Error Reporting (WER). i was not allowed to have my crash dumps, because i don't have a Verisign certificate. Instead i have a cheaper one, generated by a Verisign subsidiary: Thawte. The method in which you join is: you digitally sign a sample exe they provide. This proves that you are the same signer that signed apps that they got crash dumps from in the wild. Cryptographically, the private key is needed to generate a digital signature on an executable. Only the holder of that private key can create a signature with for the matching public key. It doesn't matter who generated that private key. That includes certificates that are generated from: self-signing Wells Fargo DigiCert SecureTrust Trustware QuoVadis GoDaddy Entrust Cybertrust GeoTrust GlobalSign Comodo Thawte Verisign Yet Microsof's WinQual only accepts digital certificates generated by Verisign. Not even Verisign's subsidiaries are good enough (Thawte). Can anyone think of any technical, legal or ethical reason why Microsoft doesn't want to accept code-signing certificates? The WinQual site says: Why Is a Digital Certificate Required for Winqual Membership? A digital certificate helps protect your company from individuals who seek to impersonate members of your staff or who would otherwise commit acts of fraud against your company. Using a digital certificate enables proof of an identity for a user or an organization. Is somehow a Thawte digital certificate not secure? Two years later, i sent a reminder notice to WinQual that i've been waiting to be able to get at my crash dumps. The response from WinQual team was: Hello, Thanks for the reminder. We have notified the appropriate people that this is still a request. In 2008 i asked this question in a Microsoft support forum, and the response was: We are only setup to accept VeriSign Certificates at this point. We have not had an overwhelming demand to support other types of certificates. What can it possibly mean to not be "setup" to accept other kinds of certificates? If the thumbprint of the key that signed the WinQual.exe test app is the same as the thumbprint that signed the executable who's crash dump you got in the wild: it is proven - they are my crash dumps, give them to me. And it's not like there's a special API to check if a Verisign digital signature is valid, as opposed to all other digital signatures. A valid signature is valid no matter who generated the key. Microsoft is free to not trust the signer, but that's not the same as identity. So that is my question, can anyone think of any practical reason why WinQual isn't setup to support digital signatures? One person theorized that the answer is that they're just lazy: Not that I know but I would assume that the team running the winQual system is a live team and not a dev team - as in, personality and skillset geared towards maintenance of existing systems. I could be wrong though. They don't want to do work to change it. But can anyone think of anything that would need to be changed? It's the same logic no matter what generated the key: "does the thumbprint match". What am i missing?

  • .com domain transfer failing

    - by digital
    Hi, I'm trying to transfer one of my .com addresses between registrars. I'm down as the owner contact (confirmed working) and the losing registrar is down as the tech and admin contact. Last week I received an email stating that the domain transfer had been rejected by the losing registrar. I contacted the losing registrar and they denied that. My money from the winning registrar was refunded and I was told to try again. I've initiated the transfer again and received confirmation of pending transfer, I gave the correct EPP code and confirmed the transfer. Currently the status on the domain is set as OK, should it not be transfer pending? According to my name.com transfer page if the transfer is not authd in 5 days it will auto transfer anyway. I don't believe this will happen. Name.com have been really helpful but they can't really do much more now. The losing registrar is not being helpful hence me turning here. What can I do to make sure the domain transfers? The domain transfer is set to expire on the 17th. Any help would be greatly appreciated.

  • Google webmaster tools: parameters that only apply on one page

    - by Imagine digital
    I'm trying to get my e-commerce website on google and still figuring out how it all works. Now, I have seen this feature named URL-parameters, allowing me to set different parameters that affect page content to be indexed (one can also set parameters that do not affect the page, but for me that does not apply..). The question I have about this is whether and how I should add parameters that I only have on some pages of my site. example: The homepage of my site is www.mysite.nl. no parameters at all. But when a user clicks the navigation bar, it links to www.mysite.nl/itemList.php?category=&....subCategory=.... The parameters category and subCategory define whether there is content on my itemList page and what content that is. It gets matching products out of my database based on those 2 variables. The question: How do I make sure that I apply the google URL Parameters function decently for my website?

  • NRF Big Show 2011 -- Part 2

    - by David Dorf
    One of the things I love about attending NRF is visiting the smaller booths to see what new innovative ideas have sprung up. After all, by watching emerging technologies we can get a sense of how the retail experience might change. After NRF I'm hoping to write a post on what I found, if anything, so be sure to check back. At the Oracle Retail booth we'll be demonstrating some of the aspects of the changing retail experience. These demos use a mix of GA and experimental components. Here are some highlights: 1. Checkin We wrote a consumer iPhone app we call Store Gateway that lets consumers access information from the store. They'll start by doing a checkin when they arrive that will alert the store manager via another iPhone app we wrote called Mobile Manager. Additionally, we display a welcome messaging using Starmount's digital sign. 2. Receive Offers There are three interaction points where a store can easily make an offer to a consumer: checkin, product scans, and checkout. For this demo we're calling our Universal Offer Engine at checkin to determine the best offer for this particular consumer. This offer is then displayed on the consumer's phone as well as on the digital sign. 3. Scan Products To thwart consumers from scanning product barcodes, we used Store Inventory Management to print QRCodes on shelf label then provided access to a scanner in the Store Gateway iphone app. When the consumer scans the shelf label they are shown product information provided by the retailer. 4. Checkout While we don't have a NFC-enabled mobile phone, we have a NFC chip that can attach to a phone. We're using this to checkout using a reader provided by ViVOTech. Tap the phone on the reader, and the POS accesses the customer#, coupons, and payment information. This really speeds the checkout process. 5. Digital Receipt After the transaction is complete, a digital copy of the receipt is sent to Intuit's QuickReceipts where consumers to store all their digital receipts. There's even an iPhone app that provides easy access to the receipts. This covers about half of what what we'll be showing, so be sure to stop by. I'll also be talking about how mobile is impacting the retail experience at the Wednesday morning session NRF Mobile Retail Initiative: a Blueprint for Action. See you at the Big Show!

  • TDC: The Developer's Conference Day One

    - by Tori Wieldt
    The Developer's Conference (TDC) kicked off Wednesday in São Paulo, Brazil. With over 3000 developers in attendance over five days, it is the premier multi-community developer conference in Brazil, organized by Globalcode. Yara Senger, one of the organizers said, "We like to say multi-community rather than multi-technology because it is interesting and benefical when various communities get together. They learn so much from each other!" TDC includes tracks on Java and several other technologies, including SOA, Python, Ruby, mobile and digital TV. In the mobile track, developers who create a Java ME app will get a Nokia S40 phone!New this year at TDC is the Java University track, sponsored by Oracle.  It is aimed at university students and professionals who are new to Java. The lectures are introductory level, with an educational focus and practical exercises. The Java track and other tracks, such as SOA, mobile and Digital TV, are getting lots of help from the expertise of Brazilian JUGS members. Thanks to GoJava, JavaBahia, JavaNoroeste and SouJava!Carlos Fernando, one of the coordinators on the Digital TV track, said "My goal is to teach developers the basics of digital TV, and show them the tools used to build interactive TV applications." Fernando explained the concept of "the second screen:" that many people watch TV and have second smart device (tablet or smartphone) with them, and this creates many opportunities for developers. For example, while watching TV, a viewer can get extra content (interviews, behind the scenes) on their tablet. More interestingly, while watching their favorite TV show a viewer likes an outfit one of the actors is wearing, their smartphone can tell them where they can buy it nearby, or they can order it online immediately. Fernando exclaimed, "The opportunities for developers are nearly infinite in the area of digital TV!" At the TDC opening keynote, Debora Palermo, Oracle University country manager for Brazil, reminded attendees that Java is present in many devices, from simple to complex, and knowledge of this platform can open many doors in the labor market. She explained Oracle's Workforce Development Program (WDP), managed by Oracle University, which allows educational institutions to deliver Oracle training. WDP allows for easy and low-cost access to Oracle training in local communities across the world. "Oracle University is committed to creating the next generation of Java developers, and WDP can make that happen," Palermo said. As of March 2012, Oracle University is partnering with Globalcode to offer WDP. Students can earn official Oracle Course Certifications, a great way to learn Java.Brazilian developers that cannot attend TDC can watch live streaming.

  • Auto-responder rule in Outlook 2010 produces double signature (but only to certain emails)

    - by Austin ''Danger'' Powers
    I have set up an auto-responder in Outlook 2010 using a custom template, as a staff member will be on vacation for 6 weeks. It works perfectly, apart from the fact certain people receive two signatures at the bottom of the message instead of one. When reviewing the "sent" folder, there is no sign of double signatures. In the custom template, there is only 1 copy of the signature. Signatures are set to be applied automatically to new messages or replies- however, if I remove the signature from the template, then it seems no one receives a response with the signature. People sending from Hotmail accounts do not receive a duplicate signature. Gmail users do see a duplicate signature. Does anyone have any idea what could be causing this?

  • PC BluRay - Multichannel HD Audio output

    - by sheepsimulator
    When playing a BluRay movie on a PC (any OS, Mac/Win/Linux), I have some questions about audio output: When playing a BluRay disc on the PC using a BluRay player program, can it decode the multichannel (7.1) LPCM/ Dolby Digital Plus / Dolby TrueHD / DTS-HD / DTS-HDMA soundtracks in their HD formats (ie, without downmixing to Dolby Digital or DTS or PCM) and output the audio directly to the soundcard's 7.1 line-level analog outputs? Is it possible to bitstream the the multichannel (7.1) LPCM/ Dolby Digital Plus / Dolby TrueHD / DTS-HD / DTS-HDMA soundtracks in their HD formats (ie, without downmixing to Dolby Digital or DTS or PCM) over the HDMI output to a receiver when using a BluRay player program? I'd kinda like to know. I'm contemplating building a home theater PC, and the above functionality is important. I'd prefer that #1 is possible, actually, because it would mean I wouldn't have to buy a receiver.

  • Making sense of S.M.A.R.T

    - by James
    First of all, I think everyone knows that hard drives fail a lot more than the manufacturers would like to admit. Google did a study that indicates that certain raw data attributes that the S.M.A.R.T status of hard drives reports can have a strong correlation with the future failure of the drive. We find, for example, that after their first scan error, drives are 39 times more likely to fail within 60 days than drives with no such errors. First errors in re- allocations, offline reallocations, and probational counts are also strongly correlated to higher failure probabil- ities. Despite those strong correlations, we find that failure prediction models based on SMART parameters alone are likely to be severely limited in their prediction accuracy, given that a large fraction of our failed drives have shown no SMART error signals whatsoever. Seagate seems like it is trying to obscure this information about their drives by claiming that only their software can accurately determine the accurate status of their drive and by the way their software will not tell you the raw data values for the S.M.A.R.T attributes. Western digital has made no such claim to my knowledge but their status reporting tool does not appear to report raw data values either. I've been using HDtune and smartctl from smartmontools in order to gather the raw data values for each attribute. I've found that indeed... I am comparing apples to oranges when it comes to certain attributes. I've found for example that most Seagate drives will report that they have many millions of read errors while western digital 99% of the time shows 0 for read errors. I've also found that Seagate will report many millions of seek errors while Western Digital always seems to report 0. Now for my question. How do I normalize this data? Is Seagate producing millions of errors while Western digital is producing none? Wikipedia's article on S.M.A.R.T status says that manufacturers have different ways of reporting this data. Here is my hypothesis: I think I found a way to normalize (is that the right term?) the data. Seagate drives have an additional attribute that Western Digital drives do not have (Hardware ECC Recovered). When you subtract the Read error count from the ECC Recovered count, you'll probably end up with 0. This seems to be equivalent to Western Digitals reported "Read Error" count. This means that Western Digital only reports read errors that it cannot correct while Seagate counts up all read errors and tells you how many of those it was able to fix. I had a Seagate drive where the ECC Recovered count was less than the Read error count and I noticed that many of my files were becoming corrupt. This is how I came up with my hypothesis. The millions of seek errors that Seagate produces are still a mystery to me. Please confirm or correct my hypothesis if you have additional information. Here is the smart status of my western digital drive just so you can see what I'm talking about: james@ubuntu:~$ sudo smartctl -a /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: WDC WD1001FALS-00E3A0 Serial Number: WD-WCATR0258512 Firmware Version: 05.01D05 User Capacity: 1,000,204,886,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Thu Jun 10 19:52:28 2010 PDT SMART support is: Available - device has SMART capability.

  • Loose component cables causing HDMI video problems

    - by jwir3
    I'm not sure this is the correct forum, but I'll ask anyway. I have an A/V setup at home that has something like the following: Five Components (actually a few more, like a CD player, but they don't really relate to this question): Older Pioneer Receiver Digital Set Top Box Sony BluRay Player Samsung Plasma TV Speakers The reason for the receiver is so that all the sound can go through the speakers, rather than some going to the TV speakers and some to the external speakers. They are connected as follows: Digital Set Top Box connects via component video to Samsung TV directly via Component 2 (audio goes to Older Pioneer Receiver). Sony BluRay player is connected via HDMI 1 to TV, but audio goes to the receiver. Now, the problem I'm having is that when I have the digital set top box connected, there are times when the Netflix or Hulu streams I watch through the Sony BluRay player (it's connected to a router for internet access) will lose video. What I mean by this is that the sound of the episode will keep playing, but the screen will go black. If I jiggle the component cables, it will often come back. If I disconnect the component cables, it will always come back. I've noticed that one of the connections (the red component cable) doesn't like to sit very well in the component socket in the back of the digital set top box. It seems like there is a bad connection here, but it doesn't seem like this should be affecting the HDMI input at all. What I've noticed, though, is that when I disconnect the digital set top box completely (i.e. remove the component cable from the back of the TV), the problem seems to resolve itself. I'm not talking about actually removing the cable physically, because I thought perhaps the cables were mashing against one another, and possibly jiggling each other loose. To correct this possible problem, I took the component cable completely out of the cable ties it was in in the back of my entertainment center, as well as pulled the digital set top box out from the entertainment center altogether. It's now connected directly to the TV, without any other cables touching it to cause some kind of weird interference or just physical pulling on the cable. Same problem. If, however, I disconnect the component cable and just leave it sitting behind the TV, then the problem goes away. So, my question is this - what could be causing this? Is it a case where it's an improperly shielded component cable that's causing interference with the HDMI input, or something that's wrong with the TV? It's an intermittent problem, so it's difficult to track down. The TV isn't that old, so it's probably still under warranty. I'm just wondering if there is something else I can do that might reduce this problem without having to haul a massive television set out of my house to get repaired/replaced.

  • How to give wife emergency access to logins, passwords, etc.?

    - by Torben Gundtofte-Bruun
    I'm the digital guru in my household. My wife is good with email and forum websites but she trusts me with all our important digital stuff -- such as online banking and other things that require passwords, but also family photos and the plethora of other digital things in a modern home. We discuss relevant actions but it's always me that executes the actions. If I should get "hit by a bus" then my wife would be thoroughly stranded -- she would have no idea what digital stuff is where on our computer, how to access it, what online accounts we have, and their login credentials are. It would also leave my many public appearances (personal websites, email accounts, social networks, etc.) unresolved. To complicate things, I'm one of those people who don't use password as my password everywhere; I use a mix of SuperGenPass and LastPass, and also two-factor authentication whenever possible. I don't have much hope that she would find her way through a written explanation of all that in a stressful situation. I could just tell her that she should ask my tech-savvy twin brother and then entrust him with my LastPass master passphrase. I feel that would have a high chance of success, but it's inelegant and leaves my wife without control of the information. How can I ensure that my wife has access to my digital remains?

    I have a few MP4s that i want to upload to my flickr account but they have a maximum size of 500mb as mine is only about 550 i was planing to simply split them in half then upload them, but i want to make sure all the meta data is included but it does not seem to be. I have tried each of the following with no luck, (at the end of this post i have the original and the new ffprobe outputs): ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4 ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_meta_data SANY0069.MP4:SANY0069A.MP4 SANY0069A.MP4 with the this one I manually produced the individual meta tags that i took from this command ffmpeg -i SANY0069A.MP4 -f ffmetadata meta.txt ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -metadata major_brand="mp42" -metadata minor_version="1" -metadata compatible_brands="mp42avc1" -metadata creation_time="2012-09-29 09:05:50" -metadata comment="SANYO DIGITAL CAMERA CA9" -metadata comment-eng="SANYO DIGITAL CAMERA CA9" SANY0069A.MP4 using the output of the former command i also tried this: ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -f ffmetadata -i meta.txt SANY0069A.MP4 Output: sample output from my first command: ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4 ffmpeg version 0.8.12, Copyright (c) 2000-2011 the FFmpeg developers built on Jun 13 2012 09:57:38 with gcc 4.6.3 20120306 (Red Hat 4.6.3-2) configuration: --prefix=/usr --bindir=/usr/bin --datadir=/usr/share/ffmpeg --incdir=/usr/include/ffmpeg --libdir=/usr/lib64 --mandir=/usr/share/man --arch=x86_64 --extra-cflags='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic' --enable-bzlib --enable-libcelt --enable-libdc1394 --enable-libdirac --enable-libfreetype --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-x11grab --enable-avfilter --enable-postproc --enable-pthreads --disable-static --enable-shared --enable-gpl --disable-debug --disable-stripping --shlibdir=/usr/lib64 --enable-runtime-cpudetect libavutil 51. 9. 1 / 51. 9. 1 libavcodec 53. 8. 0 / 53. 8. 0 libavformat 53. 5. 0 / 53. 5. 0 libavdevice 53. 1. 1 / 53. 1. 1 libavfilter 2. 23. 0 / 2. 23. 0 libswscale 2. 0. 0 / 2. 0. 0 libpostproc 51. 2. 0 / 51. 2. 0 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'SANY0069.MP4': Metadata: major_brand : mp42 minor_version : 1 compatible_brands: mp42avc1 creation_time : 2012-09-29 09:05:50 comment : SANYO DIGITAL CAMERA CA9 comment-eng : SANYO DIGITAL CAMERA CA9 Duration: 00:08:38.71, start: 0.000000, bitrate: 9142 kb/s Stream #0.0(eng): Video: h264 (Constrained Baseline), yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 9007 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc Metadata: creation_time : 2012-09-29 09:05:50 Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16, 127 kb/s Metadata: creation_time : 2012-09-29 09:05:50 File 'SANY0069A.MP4' already exists.

  • #1 O’Reilly eBook for 2010

    - by Jan Goyvaerts
    The year-end issue of O’Reilly’s author newsletter discussed the trends O’Reilly has been seeing the past few years, and their predictions for 2011. The key trend is that digital is now more than ever poised to take over print: Our digitally distributed products have grown from 18.36% of our publishing mix in 2009 to 28.09% of our mix in 2010. What is more impressive is that our digitally distributed products have produced more than double the revenue that has been lost with the decline of print. I think this is important because some say that digital cannibalizes print products. Our data indicates the contrary, as print is declining much more slowly than digital is growing. I think we may be seeing developers purchasing a print book, and then purchasing the electronic editions to search and copying code from, as the incremental cost for digital is more than reasonable. My own book seems to be leading this trend. Thanks to everyone who purchased it! And the five bestselling O’Reilly ebook products for 2010: 1) Regular Expressions Cookbook, 2) jQuery Cookbook, 3) Learning Python, 4) HTML5: Up and Running, and 5) JavaScript Cookbook. I think it’s interesting that the top five ebooks are code-intensive books. They’re great products for search and code reuse. It’s also interesting that none of the top 5 ebooks made the top 5 of print books.

  • hdmi AC-3 audio broke after upgrading from 11.10 to 12.04.3

    - by Jim LastName
    I just updated my MythBuntu 11.10 to 12.04.3. Now, when I try to play 5.1 content (ripped DVD), my TV (and receiver) plays a "chattering" sound. I check my receiver and the digital dolby light isn't on--it's in PCM mode. So, either the audio is getting sent as AC-3, but the TV and receiver think it's PCM or the AC-3 audio got converted to multichannel PCM and they can't handle it. My setup: hdmi cable from htpc to TV. TV has an s/pdif output to my receiver. I know TV sends AC-3 audio out correctly because I see digital dolby light come on when I view a digital TV channel and PCM come on when I view an old analog channel. I can connect s/pdif from my htpc to my receiver and the digital dolby light comes on and it can decode the audio just fine. It's just not sending it right over hdmi. Now for some hints to the issue: I noticed in MythTV audio setup when I select alsa:hdmi.... the description only lists 2 channel PCM audio capability. speaker-test -Dhdmi:PCH -c6 errors about a bad channel count (only -c2 works). Finally, I tried vlc and it does the same chattering sound. These all make me think this isn't a MythTV issue, it's something lower than that. I think the best way to troubleshoot this is to start at the drivers and check each layer, one at a time all the way to alsa. I just don't know what the layers are and how to do it. So, I need to find some audio troubleshooting guide to assist me. Or, if one doesn't exist, I'd appreciate some steps. Thanks much, Jim

  • The Freemium-Premium Puzzle

    The more time I spend thinking about the value of information, the more I found that digitalizing information significantly changed the 'information markets', potentially in an irreversible manner. The graph at the bottom outlines my current view. The existing business models tend to be the same in the digital and analogue information world, i.e. revenue is derived from a combination of consumers' payments and advertisement. Even monetizing 'meta-information' such as search engines isn't new. Just think of the once popular 'Who'sWho'. What really changed is the price-value ratio. The curve is pushed down, closer to the axis. You pay less for the same, or often even get more for less. If you recall the capabilities I described in relevance of information you will see that there are many additional features available for digital content compared to analogue content. I think this is a good 'blue ocean strategy' by combining existing capabilities in a new way. (Kim W.C. & Mauborgne, R. (2005) Blue Ocean Strategies. Boston: Harvard Business School Publishing.). In addition the different channels of digital information distribution significantly change the value of information. I will touch on this in one of my next blogs. Right now, many information providers started to offer 'freemium' content through digital channels, hoping to get a premium for the 'full' content. No freemium seems to take them out of business, because they are apparently no longer visible in today's most relevant channels of information consumption. But, the more freemium is provided, the lower the premium gets; a truly puzzling situation. To make it worse, channel providers increasingly regard information as a value adding and differentiating activity. Maybe new types of exclusive, strategic alliances will solve the puzzle, introducing new types of 'gate-keepers', which - to me - somehow does not match the spirit of the WWW and the generation Y's perception of information consumption and exchange.

  • Lending epub files for limited time to users

    - by JP Hellemons
    I am looking for components to build a digital library who lends people epub (ebooks) for about a week. It's like a digital version of the offline old public library. Now I have found several flash (pdf) file streaming solutions. But that would require an active internet link. And like the public library, you are able to take your books to the beach or pool on holiday abroad where you have no connection. So streaming is no option. The other file restriction method I have found was DRM, but that would require a really expensive license of Adobe Content Server 4 which is not suitable for my little hobby project. But it seems that adobe content server and Adobe Digital Editions is the only option at the moment. Or are there open source alternatives?
