• Antenna Aligner Part 3: Kaspersky

  - by Chris George

  Quick one today. Since starting this project, I've been encountering times where Nomad fails to build my app. It would then take repeated attempts at building to then see a build go through successfully. Rob, who works on Nomad at Red Gate, investigated this and it showed that certain parts of the message required to trigger the 'cloud build' were not getting through to the Nomad app, causing the HTTP connection to stall until timeout. After much scratching heads, it turns out that the Kaspersky Internet Security system I have installed on my laptop at home, was being very aggressive and was causing the problem. Perhaps it's trying to protect me from myself? Anyway, we came up with an interim solution why the Nomad guys investigate with Kaspersky by setting Visual Studio to be a trusted application with the Kaspersky settings and setting it to not scan network traffic. Hey presto! This worked and I have not had a single build problem since (other than losing internet connection, or that embarrassing moment when you blame everyone else then realise you've accidentally switched off your wireless on the laptop).

• In search of database delivery practitioners and enthusiasts

  - by Claire Brooking

  We know from speaking with many of you at tradeshows and user groups that database delivery is not a factory production line. During planning, evaluation, quality control, and disaster mitigation, the people having their say at each step means that successful database deployment is a carefully managed course of action. With so many factors involved at every stage, we would love to find a way for our software to help out, by simplifying processes, speeding them up or joining together the people and the steps that make it all happen. We’re hoping our new research group for database delivery (SQL Server and Oracle) will help us understand the views and experiences of those of you out there in the trenches managing database changes. As part of our new group, we’ll be running a variety of research sessions, including surveys and phone interviews, over coming months. If you have opinions to share on Continuous Integration or Continuous Delivery for databases, we’d love to hear from you. Your feedback really will count as the product teams at Red Gate build plans. For some of our more in-depth sessions, we’ll also be offering participants an Amazon voucher as a thank-you for your time. If you’re not yet practising automated database deployment processes, but are contemplating or planning it, please do consider joining our research group too. If you’d like to sign up to the group and find out more, please fill in a quick form online, and we’ll be in touch to let you know about new research opportunities you might be interested in. We look forward to hearing your stories!

• Are XML Comments Necessary Documentation?

  - by Bob Horn

  I used to be a fan of requiring XML comments for documentation. I've since changed my mind for two main reasons: Like good code, methods should be self-explanatory. In practice, most XML comments are useless noise that provide no additional value. Many times we simply use GhostDoc to generate generic comments, and this is what I mean by useless noise: /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } To me, that's obvious. Having said that, if there were special instructions to include, then we should absolutely use XML comments. I like this excerpt from this article: Sometimes, you will need to write comments. But, it should be the exception not the rule. Comments should only be used when they are expressing something that cannot be expressed in code. If you want to write elegant code, strive to eliminate comments and instead write self-documenting code. Am I wrong to think we should only be using XML comments when the code isn't enough to explain itself on its own? I believe this is a good example where XML comments make pretty code look ugly. It takes a class like this... public class RawMaterialLabel : EntityBase { public long Id { get; set; } public string ManufacturerId { get; set; } public string PartNumber { get; set; } public string Quantity { get; set; } public string UnitOfMeasure { get; set; } public string LotNumber { get; set; } public string SublotNumber { get; set; } public int LabelSerialNumber { get; set; } public string PurchaseOrderNumber { get; set; } public string PurchaseOrderLineNumber { get; set; } public DateTime ManufacturingDate { get; set; } public string LastModifiedUser { get; set; } public DateTime LastModifiedTime { get; set; } public Binary VersionNumber { get; set; } public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } } ... And turns it into this: /// <summary> /// Container for properties of a raw material label /// </summary> public class RawMaterialLabel : EntityBase { /// <summary> /// Gets or sets the id. /// </summary> /// <value> /// The id. /// </value> public long Id { get; set; } /// <summary> /// Gets or sets the manufacturer id. /// </summary> /// <value> /// The manufacturer id. /// </value> public string ManufacturerId { get; set; } /// <summary> /// Gets or sets the part number. /// </summary> /// <value> /// The part number. /// </value> public string PartNumber { get; set; } /// <summary> /// Gets or sets the quantity. /// </summary> /// <value> /// The quantity. /// </value> public string Quantity { get; set; } /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } /// <summary> /// Gets or sets the lot number. /// </summary> /// <value> /// The lot number. /// </value> public string LotNumber { get; set; } /// <summary> /// Gets or sets the sublot number. /// </summary> /// <value> /// The sublot number. /// </value> public string SublotNumber { get; set; } /// <summary> /// Gets or sets the label serial number. /// </summary> /// <value> /// The label serial number. /// </value> public int LabelSerialNumber { get; set; } /// <summary> /// Gets or sets the purchase order number. /// </summary> /// <value> /// The purchase order number. /// </value> public string PurchaseOrderNumber { get; set; } /// <summary> /// Gets or sets the purchase order line number. /// </summary> /// <value> /// The purchase order line number. /// </value> public string PurchaseOrderLineNumber { get; set; } /// <summary> /// Gets or sets the manufacturing date. /// </summary> /// <value> /// The manufacturing date. /// </value> public DateTime ManufacturingDate { get; set; } /// <summary> /// Gets or sets the last modified user. /// </summary> /// <value> /// The last modified user. /// </value> public string LastModifiedUser { get; set; } /// <summary> /// Gets or sets the last modified time. /// </summary> /// <value> /// The last modified time. /// </value> public DateTime LastModifiedTime { get; set; } /// <summary> /// Gets or sets the version number. /// </summary> /// <value> /// The version number. /// </value> public Binary VersionNumber { get; set; } /// <summary> /// Gets the lot equipment scans. /// </summary> /// <value> /// The lot equipment scans. /// </value> public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } }

• New Book - Oracle ADF Enterprise Application Development Made Simple

  - by Shay Shmeltzer

  It's nice to see another ADF book out there, this one from Sten Vesteli titled "Oracle ADF Enterprise Application Development Made Simple" comes from Packet Publishing Unlike other ADF books out there, this one doesn't aim to teach you Oracle ADF, but rather focuses on the right way to structure and manage a project that leverages ADF. This is a welcomed addition to the bookshelf for people who are looking into ADF based development. One thing I find is that some organization just start developing an ADF application without first doing much planning, something that is understandable given that it is very easy to start building a prototype with ADF and then just grow it into a full blown application. However, as the book points out, doing a bit of planning before you delve into the actual project development can save you a lot of time in the future. For example it is much better to have the right breakdown and structure of your project to allow you to do efficient team development right out of the gate, then to find out 1 year down the road that you are dealing with one monolithic size project which is hard to manage. The book touches on such topics as project organization (workspaces, projects, packages), planning your infrastructure (templates, framework classes), coding standards, team structure, etc. It also covers various aspects of application lifecycle management such as versioning, build, testing, deployment and managing requirements and tasks and how all of those are done when using JDeveloper and Oracle ADF. It's nice to see that the book covers working with Oracle Team Productivity Center - a solution that might not be getting the exposure it deserves. The book also has some chapters about security, internalization and customization of applications both with MDS and with ADF Faces skins (and it even covers the brand new skin editor). Overall I think this is definitely a book you should read if you are about to start your way on a new enterprise scale ADF application. Taking into account the topics that the book discusses before you start your work will save you time and effort down the road. By the way, don't forget that as an OTN member you can get discount on this and other books.

• Viewing and deleting partitions using the BIOS?

  - by cluelesscoder

  I have an M4A785TD-M EVO Asus motherboard which uses Asus Express Gate for its motherboard (says American Megatrends, Inc at the bottom). I activate it by pressing Del; also says Tab activates BIOS Post but that doesn't seem to do anything. I went into this expecting to see a breakdown of the partitions. I have a 300GB hard-drive separated into 3 partitions. While it does show SATA for my main hard-drive and my disk drive, it doesn't show the partitions. Is this typical? Do I have to us an OS-based tool to delete the partitions or can I delete using my BIOS? I tried updating the BIOS through Asus's Update utility but it appears to be broken (connects/disconnects repeatedly). I used HWiNFO32 to get some information: BIOS Date: 06/30/10 BIOS Version: 2103 EFI BIOS: Not Capable Tried to update but it directs me to biosagentsplus.com which wants $30 for the download (another question would be how to avoid them).

• Fuzzy Sound / Crackling

  - by Walter White

  Whenever I play music through my headphones on my laptop, I get a little bit of fuzz or cracking that is noticeable at lower volumes. When I listen through my phone, the sound is much clearer, both when music is playing and nothing is playing. The noise is more noticeable with my Sennheiser 280 PRO headphones than with earbuds. Is there anything I can do to improve audio playback on my laptop? I am surprised that the audio quality is better on my phone than my laptop which should have better hardware.

• hdmi audio works only with aplay -D alsa test wavs; open source radeon drivers; kernel 3.5 vgaswitcheroo

  - by user108754

  I've trolled the internets to make hdmi work on my system Ubuntu 12.04 software center kernel 3.5 uname: Linux ubuntu 3.5.0-18-generic #29~precise1-Ubuntu SMP...x86_64 x86_64 x86_64 GNU/Linux open source radeon drivers vgaswitcheroo (hybrid intel/radeon gpu): I boot with intel, not radeon, running. (and recall that with kernel 3.5, vgaswitcheroo now gives info on a third item, "DIS-Audio"; it indicates pwr on my system) ( /etc/rc.local: chown user:user /sys/kernel/debug/ # change "username" with your user name echo OFF /sys/kernel/debug/vgaswitcheroo/switch ) grub indeed now has "radeon.audio=1" for testing audio, I did aplay -l which gave me the card and device, which made me try aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav and lo! I get crystal clear sound on my hdtv. If I play an mp3 file as the argument to that command, I get noise as, I guess, aplay interprets the mp3 code as a wav. If I play a .wav that is not in the /usr/share/sounds/alsa/ directory, I get nothing. Internet flash video in browser plays no sound over hdmi. Both system sounds control and pavucontrol have hdmi cedar selected. Alas, I can not get sound for any gui test (left, right). Why would only aplay, and only when directed with "-D plughw", yield sound over hdmi? I've also tried only using one sound program at a time, if it was a limitation of alsa, so I tried aplay with web browser and even the sound control gui closed. I tried each of the last two, running alone. No improvement. alsamixer only shows hda intel and I think it's only the intel audio, not the hdmi.

• How to code Time Stop or Bullet Time in a game?

  - by David Miler

  I am developing a single-player RPG platformer in XNA 4.0. I would like to add an ability that would make the time "stop" or slow down, and have only the player character move at the original speed(similar to the Time Stop spell from the Baldur's Gate series). I am not looking for an exact implementation, rather some general ideas and design-patterns. EDIT: Thanks all for the great input. I have come up with the following solution public void Update(GameTime gameTime) { GameTime newGameTime = new GameTime(gameTime.TotalGameTime, new TimeSpan(gameTime.ElapsedGameTime.Ticks / DESIRED_TIME_MODIFIER)); gameTime = newGameTime; or something along these lines. This way I can set a different time for the player component and different for the rest. It certainly is not universal enough to work for a game where warping time like this would be a central element, but I hope it should work for this case. I kinda dislike the fact that it litters the main Update loop, but it certainly is the easiest way to implement it. I guess that is essentialy the same as tesselode suggested, so I'm going to give him the green tick :)

• How do client-server cooperation based games like Diablo 3 work?

  - by edgar

  Diablo 3 cooperates with Blizzard servers even during single player games. In fact, Blizzard has had problems with the games "melting their servers." I would like to ask: How do the client and the server communicate? What details does the client leave to the server, and vice versa? What details are redundant - both the client and the server know - and how often do they disagree? The previous paragraph contains the important questions, but I have a few more that I must explain my motivation towards. I am interested in the programming of botting. Ethical botting - I don't plan on actually abusing the automation to run 24/7. I just find it to be a great programming challenge to glean information from a game, and then make decisions from that information. I am stuck in the starting gate. The unofficial questions from this post would be: How can I make a bot (language, tools, libraries)? Can I get information through the communication between client and server, rather than the brute force pixel detection easily used in more static games? There probably is a trust issue, and to that all I can say is that I promise not to abuse the answers. But please feel free to answer any of the questions you feel comfortable with. Thank you!

• Dell Mini 9 Integrated Microphone -- not working

  - by Josh Eismanaf

  Im running the latest Debian version, 6.0 on my Dell Mini 9.Webcam and sound work, but microphone is a no-go. I hope even though it is Debian, fellow Linux users can help. In Alsamixer (1.0.23), I have Capture, Digital, and Mic settings all the way up. There are no options for adjusting "Front" mic settings. (May have been for older alsamixer versions?) In Sound Recorder, playback has loud noise/feedback? Under Preferences in Volume Control under the Recording tab, both Capture and Digital are permanently checked, regardless if I uncheck them. I'm not sure how to interpret the above, but I am just trying to offer as much relevant background information as I can. I've been scouring forums for the answer, but to no avail. Most questions/answers are from 2008, and couldn't find a solution. I'm not very handy with the Linux machine, but love to learn / am learning. Also, I've attempted the solution here, and it didn't work. Thanks, in advance, for your help!

• Should the syntax for disabling code differ from that of normal comments?

  - by deltreme

  For several reasons during development I sometimes comment out code. As I am chaotic and sometimes in a hurry, some of these make it to source control. I also use comments to clarify blocks of code. For instance: MyClass MyFunction() { (...) // return null; // TODO: dummy for now return obj; } Even though it "works" and alot of people do it this way, it annoys me that you cannot automatically distinguish commented-out code from "real" comments that clarify code: it adds noise when trying to read code you cannot search for commented-out code for for instance an on-commit hook in source control. Some languages support multiple single-line comment styles - for instance in PHP you can either use // or # for a single-line comment - and developers can agree on using one of these for commented-out code: # return null; // TODO: dummy for now return obj; Other languages - like C# which I am using today - have one style for single-line comments (right? I wish I was wrong). I have also seen examples of "commenting-out" code using compiler directives, which is great for large blocks of code, but a bit overkill for single lines as two new lines are required for the directive: #if compile_commented_out return null; // TODO: dummy for now #endif return obj; So as commenting-out code happens in every(?) language, shouldn't "disabled code" get its own syntax in language specifications? Are the pro's (separation of comments / disabled code, editors / source control acting on them) good enough and the cons ("shouldn't do commenting-out anyway", not a functional part of a language, potential IDE lag (thanks Thomas)) worth sacrificing? Edit I realise the example I used is silly; the dummy code could easily be removed as it is replaced by the actual code.

• Understanding Asynchronous Programming with .NET Reflector

  - by Nick Harrison

  When trying to understand and learn the .NET framework, there is no substitute for being able to see what is going on behind at the scenes inside even the most confusing assemblies, and .NET Reflector makes this possible. Personally, I never fully understood connection pooling until I was able to poke around in key classes in the System.Data assembly. All of a sudden, integrating with third party components was much simpler, even without vendor documentation!With a team devoted to developing and extending Reflector, Red Gate have made it possible for us to step into and actually debug assemblies such as System.Data as though the source code was part of our solution. This maybe doesn’t sound like much, but it dramatically improves the way you can relate to and understand code that isn’t your own.Now that Microsoft has officially launched Visual Studio 2012, Reflector is also fully integrated with the new IDE, and supports the most complex language feature currently at our command: Asynchronous processing.Without understanding what is going on behind the scenes in the .NET Framework, it is difficult to appreciate what asynchronocity actually bring to the table and, without Reflector, we would never know the Arthur C. Clarke Magicthat the compiler does on our behalf.Join me as we explore the new asynchronous processing model, as well as review the often misunderstood and underappreciated yield keyword (you’ll see the connection when we dive into how the CLR handles async).Read more here

• Tomcat log include servlet context

  - by Kris

  I have a Tomcat instance running several websites. Recently I've been trying to deal with the various error messages that wind up in the Tomcat log file (catalina.out). None of the issues are affecting the websites, but all the noise is making it difficult to see actual problems. My problem is that frequently the message is being emitted by a library that is used by multiple webapps. Unless a stacktrace is included (which it often isn't) I can't tell which webapp is responsible without a lot of digging. So the question is, can I somehow configure Tomcat to include the servlet context in the log file? Or perhaps have different log files per context?

• Unexpected network traffic?

  - by robwalker

  My internet connection is via a fixed wireless connection using a 900MHz Motorola Canopy module. The router reports a fairly consistent 32-64Kbps of incoming traffic on the WAN port. When I attached a PC directly to the port and run Wireshark, I get a dump showing a lot of chatter from other machines that I presume are connected to the same tower. This didn't include end-to-end traffic, but was there were a lot of ARP requests, SSDP traffic, ICMP and other network discovery type stuff. Is this 'normal' or does it suggest a misconfiguration somewhere? As far as I can tell there is no need for my modem to be receiving any of this traffic (other than wanting to know what the names of my neighbours machines and printers are!) Since the internet connection is slow at the best of time, having this amount of background noise seems very wasteful.

• Any good reason open files in text mode?

  - by Tinctorius

  (Almost-)POSIX-compliant operating systems and Windows are known to distinguish between 'binary mode' and 'text mode' file I/O. While the former mode doesn't transform any data between the actual file or stream and the application, the latter 'translates' the contents to some standard format in a platform-specific manner: line endings are transparently translated to '\n' in C, and some platforms (CP/M, DOS and Windows) cut off a file when a byte with value 0x1A is found. These transformations seem a little useless to me. People share files between computers with different operating systems. Text mode would cause some data to be handled differently across some platforms, so when this matters, one would probably use binary mode instead. As an example: while Windows uses the sequence CR LF to end a line in text mode, UNIX text mode will not treat CR as part of the line ending sequence. Applications would have to filter that noise themselves. Older Mac versions only use CR in text mode as line endings, so neither UNIX nor Windows would understand its files. If this matters, a portable application would probably implement the parsing by itself instead of using text mode. Implementing newline interpretation in the parser might also remove some overhead of using text mode, as buffers would need to be rewritten (and possibly resized) before returning to the application, while this may be less efficient than when it would happen in the application instead. So, my question is: is there any good reason to still rely on the host OS to translate line endings and file truncation?

• Laptop turns off after 20 minutes of use

  - by Christoph

  My laptop a sony vaio VGN-NW11S http://www.trustedreviews.com/Sony-VAIO-VGN-NW11S-S---15-5in-Laptop_Laptop_review. Everytime i turn it on, in safe mode or not, if i try to open an application i.e. run a process such as google chrome or event viewer, defrag, virus scan, it completely turns off without warning, nor giving a trace of events the next time I switch it on. Apart from that, I had worries it might be my battery or power supply but I dont think it is that, I took the laptop apart cleaning fans etc. and have ordered some cpu paste as I checked to see the condition of the processor. I will post to see if re-applying the paste works. One more thing, when the heavy processes kick in, the fan starts to make a lot of noise, maybe trying to cool down the CPU? Any ideas on what else it could be and what I could do to test what is wrong?

• Skype 2.1beta for Linux and sound quality

  - by vava

  I've been using Skype 2.1beta for Linux with my bluetooth headset and quality of the sound is just awful. But not always though, if I call echo service, quality is acceptable, but when I call real people there's echo, sound is crippling, there's pauses, voice is unrecognizable, all sorts of quality problems in one call. If I use newest Skype under WIndows with the same headset to call to the same people, quality is more than normal. So, is there some settings I can tweak, like tell Skype which codec to use or maybe there's noise cancellation plugin for PulseAudio I can use or any other system setting I can try to play with?

• Best FFDShow settings for upscaling SD content to 1080p HD?

  - by Richard

  Hi there, I'm running Windows Media Center 7 with ffdshow-tryouts for the decoding of many of the popular video formats. It works great. I've now upgraded my television from SD to 1080p HD and, naturally, I've still got a large number of existing MP4/XviD/DivX items of content which is in SD. I'd like, therefore, to modify the settings of ffdshow so that they are upscaled to 1080p as best as possible. I appreciate that they won't be as good as their HD equivalent - but on the flip side, I'm pretty certain I can do more than just resizing the picture to get the best possible output. Can anyone recommend the best settings in ffdshow to do this? For example, should I apply a sharpen mask? Or Noise Reduction? Or Deinterlace? Alternatively, would it be better to keep them at their current resolution and let the TV (Samsung Series 5 LE32C580) do the upscaling? Thanks.

• An experiment: unlimited free trial

  - by Alex.Davies

  The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

• how to make a continuous machine gun sound-effect

  - by Jan

  I am trying to make an entity fire one or more machine-guns. For each gun I store the time between shots (1.0 / firing rate) and the time since the last shot. Also I've loaded ~10 different gun-shot sound-effects. Now, for each gun I do the following: function update(deltatime): timeSinceLastShot += deltatime if timeSinceLastShot >= timeBetweenShots + verySmallRandomValue(): timeSinceLastShot -= timeBetweenShots if gunIsFiring: displayMuzzleFlash() spawnBullet() selectRandomSound().play() But now I often get a crackling noise (which I assume is when two or more guns are firing at the same time and confuse the sound-device). My question is whether A) This a common problem and there is a well-known solution, maybe to do with the channels or something, or B) I am using a completely wrong approach to the task. I had a look at some sound-assets for other games and they used complete burst with multiple shots. I suppose I could try that, but I would like to have organic little hickups in the gun-fire (that's what the random value is for) to make the game more gritty and dirty. I am using Panda3D, but I had the exact same problem in PyGame and SDL. [edit] Thanks a lot for the answers so far! One more problem with faking it though: Now how do I stop the sound? Let's say I have an effect with 5 bangs... *bang* *bang* *bang* *bang* *bang* And I magically manage to loop it so that there's no gap or overlap if the player fires more than 5 shots. Now, what do I do if the player stops firing halfway through the third bang? How do I know how long to keep playing the sample so that the third bang is completed and I can start playing the rumbling echo of the last shot? Of course I can look up the shot/pause timing of that sound-sample and code accordingly, but it feels extremely hacky.

• Artefacts during HDV capture

  - by Jakub Konecki

  When I try to capture HDV video stream from a Canon HV20 camera to a Dell Studio 1558 (Intel i7 720qm) laptop running Win 7 Home Premium x64, the image appears with a very annoying noise - it contains block artefacts. Something is wrong with the Fire Wire controller (Ricoh 1304 OHCI host controller, build-in). Tried changing the driver to legacy one to no avail. This does not happen with DV stream. I'm using a Belkin cable. The capture works OK on another machine.

• A Fresh Start

  - by Laila

  As you may already be aware, I'm no longer responsible for the .NET Reflector newsletter. That publication is now in the very capable hands of the Reflector team. But fear not; starting in early April, I'll be launching a brand new .NET Newsletter, and I invite you to enjoy the very first edition by subscribing to our new mailing list, or by updating your Simple-Talk subscriptions, and joining the .NET Newsletter mailing list. With a fresh and snappy design (it might even be described as idiosyncratic. but I can say no more at this stage), we'll be making a brand new start. Each month, a member of my team (that's the Red Gate .NET team) will host the .NET Newsletter, bringing you the choicest cuts of breaking news, the very best .NET content from Simple-Talk, alongside details of hot upcoming events. To top it off, not only will you be among the first to get access to free resources (including free wall-charts, training videos and eBooks), but you'll also get exclusive access to betas, early access programs, and special offers. We can't wait to share the new design and exciting new content with you! If you have any questions about the changes to the newsletter, please feel free to send an email to [email protected] or post a comment on my blog. If I don't hear from you before next month, then I'll simply say that I hope you enjoy the new look. Cheers, Laila
