• My datacenter is unable to add PTR/rDNS record, then how can I prevent the mail outgoing from going to spam folder?

  - by gilzero

  I am having problem that mail sent out from my server all goes to recipient's spam folder. I am running Drupal sites on Linux server. CentOS w/ cPanel. Our users cannot receive email as the mail went to the spam folder. (such as registration email, contact form email) I was advised that I need to have PTR/rDNS record added for my host. I then contact my datacenter to add PTR/rDNS thing, unfortunately, the datacenter said they are unable to do it. So what can I do? Any other ways I can fix the problem? Thank you!

• "The protocol 'net.msmq' is not supported."

  - by Randolpho St. John

  OMG, a new lesson! Will wonders never cease? So I ran into an interesting issue setting up a WCF service to consume an MSMQ queue. I won't bother you with the details of how to actually build a WCF/MSMQ service; there are plenty of tutorials on the subject. I want to share with you an interesting error that I ran into and the surprisingly simple fix. The error occurs when attempting to generate a Service Reference or even simply browsing to the WSDL of your WCF/MSMQ service in the form of a YSOD with the following error: "The protocol 'net.msmq' is not supported." After a lot of Googling on the subject turning up plenty of questions with the same error but no answers. So I went digging into some application level config files on a server that already had a WCF/MSMQ service successfully set up by the network admin, and the answer was amazingly simple: If you are hosting an MSMQ/WCF service in IIS, you have to tell IIS to allow net.msmq protocol. It's in the advanced settings for the application or site in which you are hosting the service. .... aaaand, that's it.

• ubuntu 12.04 desktop Error: unknown command 'gfxmode'. Pressing any key continues

  - by Andy

  Premise: linux noobie here, I have the same issue as OP: fresh 12.04 desktop, changed grub with grub customizer, now I get a: unknown command 'gfxmode' press ...etc was asked to "re-post" this question and link to this thread which I refer to above. I have tried what Tarek said, and nothing seems to work, I find two lines with gfxmode: function gfxmode { gfxmode \$linux_gfx_mode Note: not sure if it matter but in the error the two single quotes before gfxmode are not the same, the first is a slanted quote mark, the second (after gfxmode) is a straight one. I commented out the whole line, I tried to add 'set' before gfxmode, neither did any difference. I found another place that said to remove the line from another file 40_custom, but I checked and those files do not contain anything relating to the line we are looking for: gfxmode $linux_gfx_mode Not sure what I am missing, but the file linux.save has recently appeared when searching for the line. Not sure if its just a temp file of some kind. In any case I cannot seem to get it, what am I missing? Thanks! P.S. sorry for any messups in form :)

• Making Modular, Reusable and Loosely Coupled MVC Components

  - by Dusan

  I am building MVC3 application and need some general guidelines on how to manage complex client side interaction between my components. Here is my definition of one component in general way: Component which has it's own controller, model and view. All of the component's logic is placed inside these three parts and component is sort of "standalone", it contains it's own form, data needed for interaction, updates itself with Ajax and so on. Beside this internal logic and behavior of the component, it needs to be able to "Talk" to the outside world. By this I mean it should provide data and events (sort of) so when this component gets embedded in pages can notify other components which then can update based on the current state and data. I have an idea to use client ViewModel (in java-script) which would hookup all relevant components on page and control interaction between them. This would make components reusable, modular - independent of the context in which they are used. How would you do this, I am a bit stuck as I do not know if this is a good approach and there is a technical possibility to achieve this using java-script/jquery. The confusing part is about update via Ajax, how to ensure that component is properly linked to ViewModel when component is Ajax updated (or even worse removed or dynamically added). Also, how should this ViewModel be constructed and which technicalities to use here and in components to work as synergy??? On the web, I have found the various examples of the similar approach, but they are oversimplified (even for dummies) or over specific and do not provide valuable resource or general solution for this kind of implementation. If you have some serious examples it would be, also, very helpful. Note: My aim is to make interactions between many components on the same page simpler and more robust and elegant.

• Intel SASWT4I SAS/SATA Controller Question

  - by Joe Hopfgartner

  Hey there! I want to assemble a cheap storage sytem based on the Norco RPC-4020 Case. When searching for controllers I found this one: Intel® RAID Controller SASWT4I This is a quote form the Spec Sheet: Scalability. Supports up to 122 physical devices in SAS mode which is ideal for employing JBODs (Just a Bunch Of Disks) or up to 14 devices in RAID 0, 1, 1E/10E mode through direct connect device attachment or through expander backplane support. Does that mean I can attatch 14 SATA drives directly to the controller using SFF-8087 - 4x SATA breakout cables? That would be nice because then I can choose a mainboard that has 6 Onboard SATA and i can connect all 20 bays while only spending 155$ on the controller and like another 100$ on cables. Would that work? And why is it 14 and not 16 when there are 4 Ports? I am really confused about all the breakout/fanout/(edge-)expanding/multiplying/channel stuff...

• 2.5" SSD in a 3.5" desktop drive bay normal?

  - by Cory Petosky

  I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor. Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!

• Suggestions for a Live chat software on websites for customer support?

  - by Munish Goyal

  Recommendations needed. We want to get in touch with customers via live chat. Requirements: chat window customisable to mingle with website theme (colors etc) preferably the window should be within webpage and not only pop-out/popup. ease of use by customer minimally intrusive should have triggers/Alerts to backend side. for ex: user is unable to fill-up signup form or something, we should be able to offer help to user and this chat window automatically shows to user. What is the cost ? UPDATE: After R&D we also narrowed down to comm100 and liveperson, and we will go with comm100. LP is best commerical soln. but comm100 is a good free soln. We go with comm100 as starting point. But it gives out exceptions alerts sometimes in the dashboard. Can it be configured for chat invitations triggered on certain conditions. Currently only a timebased trigger is available. Any other major difference between these two ?

• How to monetize and protect a engine's and its framework's copyrights and patents?

  - by Arthur Wulf White

  I created a game engine that handles: Rendering levels with 2d textured curved surfaces Collisions with curved surfaces Animationn paths on and navigation in 2d-sapce I have also made a framework for: Procedural organic level generation with round surfaces Level editing Light weight sprite design The engine and framework are written in AS3 and I am in the process of translating the code into HaXe to better support other platforms. I am also interested in adding Animated curved platforms More advanced level editing features Currently, I have a part time job and any time I spend on this engine is either taken out of my limited free time (I'm a student working to support myself through school) or out my time working at my job. I really believe this engine can make life much easier for people designing Tower Defence games, Shooters and and Platformers while also possibly improving their results. It could also support RTS, RPGs and racing games very well. It continains original algorithms that could be used for procedural generation of organic round and smooth levels. The algorithms I used are new and are not available in any other level editor I've seen. In order to constantly improve the Engine and have it tested thoroughly I think the best route is releasing it to the public. What are the best ways to benefit myself and others with my new framework? I want to have some lisence, allowing me to share the framework and still benefit from it. Any advice would be appreciated. This issue has been on my mind a lot this year. I am hoping to find a solution that will bring me some relief. I am thinking of designing three sample games, releasing them and starting a kickstarter, any advice and thoughts on the matter would be valuable. My goal is like Markus von Broady suggested, to get people involved in developing the engine and let people use it for games for either a symbolic fee or for free and charge for support. That or use some form of croud sourcing. Do I need to hire a lawyer to get some sort of legal document to protect my work?

• Managing products on a an ecommerce site [closed]

  - by John

  I've had a site that sells widgets for many years. I do not inventory my widgets, but the cost of adding them to the site and makings sure the site is current is becoming cost prohibitive. Here are the facts: I sell a single class of widget. I have about 50,000 widgets on my site. I have about 100 vendors that create and dropship the products when they get an order from me via email. Each vendor carries from 50 to 5000 types of widgets. Vendors all have websites with images and descriptions of their products. Each widget is produced in limited supply and usually sell out in 1-5 years. Prices of the widget often go up, sometimes more than 50% before they sell out. My vendors aren't very tech sophisticated. They have websites with their products, but most can't supply an api or database dump. Their websites usually display retail prices to the public, but I login or refer to a price list (usually excel) for wholesale prices. As it stands now, I hire local people to add and describe each widget to our website. It usually takes a person 4 minutes to add a widget to the site. This doesn't include moving to a new vendor. I feel like the upload/edit process is as good as it can get via a form/website. The problem is that it is getting very expensive to upload and keep the widget inventory current. I often get orders for something after it's sold out from the vendor or the price is wrong. This seems like it would be a problem in many industries. Can anyone suggest the cheapest way to upload inventory and ensure prices are current from my vendors? I'm assuming it will involve outsourcing, but I would like ideas on how to setup the compensation model.

• Writing Acceptance test cases

  - by HH_

  We are integrating a testing process in our SCRUM process. My new role is to write acceptance tests of our web applications in order to automate them later. I have read a lot about how tests cases should be written, but none gave me practical advices to write test cases for complex web applications, and instead they threw conflicting principles that I found hard to apply: Test cases should be short: Take the example of a CMS. Short test cases are easy to maintain and to identify the inputs and outputs. But what if I want to test a long series of operations (eg. adding a document, sending a notification to another user, the other user replies, the document changes state, the user gets a notice). It rather seems to me that test cases should represent complete scenarios. But I can see how this will produce overtly complex test documents. Tests should identify inputs and outputs:: What if I have a long form with many interacting fields, with different behaviors. Do I write one test for everything, or one for each? Test cases should be independent: But how can I apply that if testing the upload operation requires that the connect operation is successful? And how does it apply to writing test cases? Should I write a test for each operation, but each test declares its dependencies, or should I rewrite the whole scenario for each test? Test cases should be lightly-documented: This principles is specific to Agile projects. So do you have any advice on how to implement this principle? Although I thought that writing acceptance test cases was going to be simple, I found myself overwhelmed by every decision I had to make (FYI: I am a developer and not a professional tester). So my main question is: What steps or advices do you have in order to write maintainable acceptance test cases for complex applications. Thank you.

• Kill xserver from command line (init 3/5 does not work)

  - by John Smith

  Hi, I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

• Sharepoint 2007 - Transaction log full

  - by Kenny Bones

  So I have this SharePoint 2007 site that is basically trash. I'm supposed to just toss it, but I'm in need of copying all of the data in form of traditional files and folders from certain projects. And since the transaction log is full, it's so damn slow. Even opening SharePoint takes up to 15 minutes, or it won't open at all. Copying of files is extremely slow. So I'm in need of a quick fix here. Just to be able to copy out some files and folders. I don't need to fix the problem per se. What can I do to fix it temporarily to be able to copy out the data?

• Changes to the LINQ-to-StreamInsight Dialect

  - by Roman Schindlauer

  In previous versions of StreamInsight (1.0 through 2.0), CepStream<> represents temporal streams of many varieties: Streams with ‘open’ inputs (e.g., those defined and composed over CepStream<T>.Create(string streamName) Streams with ‘partially bound’ inputs (e.g., those defined and composed over CepStream<T>.Create(Type adapterFactory, …)) Streams with fully bound inputs (e.g., those defined and composed over To*Stream – sequences or DQC) The stream may be embedded (where Server.Create is used) The stream may be remote (where Server.Connect is used) When adding support for new programming primitives in StreamInsight 2.1, we faced a choice: Add a fourth variety (use CepStream<> to represent streams that are bound the new programming model constructs), or introduce a separate type that represents temporal streams in the new user model. We opted for the latter. Introducing a new type has the effect of reducing the number of (confusing) runtime failures due to inappropriate uses of CepStream<> instances in the incorrect context. The new types are: IStreamable<>, which logically represents a temporal stream. IQStreamable<> : IStreamable<>, which represents a queryable temporal stream. Its relationship to IStreamable<> is analogous to the relationship of IQueryable<> to IEnumerable<>. The developer can compose temporal queries over remote stream sources using this type. The syntax of temporal queries composed over IQStreamable<> is mostly consistent with the syntax of our existing CepStream<>-based LINQ provider. However, we have taken the opportunity to refine certain aspects of the language surface. Differences are outlined below. Because 2.1 introduces new types to represent temporal queries, the changes outlined in this post do no impact existing StreamInsight applications using the existing types! SelectMany StreamInsight does not support the SelectMany operator in its usual form (which is analogous to SQL’s “CROSS APPLY” operator): static IEnumerable<R> SelectMany<T, R>(this IEnumerable<T> source, Func<T, IEnumerable<R>> collectionSelector) It instead uses SelectMany as a convenient syntactic representation of an inner join. The parameter to the selector function is thus unavailable. Because the parameter isn’t supported, its type in StreamInsight 1.0 – 2.0 wasn’t carefully scrutinized. Unfortunately, the type chosen for the parameter is nonsensical to LINQ programmers: static CepStream<R> SelectMany<T, R>(this CepStream<T> source, Expression<Func<CepStream<T>, CepStream<R>>> streamSelector) Using Unit as the type for the parameter accurately reflects the StreamInsight’s capabilities: static IQStreamable<R> SelectMany<T, R>(this IQStreamable<T> source, Expression<Func<Unit, IQStreamable<R>>> streamSelector) For queries that succeed – that is, queries that do not reference the stream selector parameter – there is no difference between the code written for the two overloads: from x in xs from y in ys select f(x, y) Top-K The Take operator used in StreamInsight causes confusion for LINQ programmers because it is applied to the (unbounded) stream rather than the (bounded) window, suggesting that the query as a whole will return k rows: (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) The use of SelectMany is also unfortunate in this context because it implies the availability of the window parameter within the remainder of the comprehension. The following compiles but fails at runtime: (from win in xs.SnapshotWindow() from x in win orderby x.A select win).Take(k) The Take operator in 2.1 is applied to the window rather than the stream: Before After (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) from win in xs.SnapshotWindow() from b in     (from x in win     orderby x.A     select x.B).Take(k) select b Multicast We are introducing an explicit multicast operator in order to preserve expression identity, which is important given the semantics about moving code to and from StreamInsight. This also better matches existing LINQ dialects, such as Reactive. This pattern enables expressing multicasting in two ways: Implicit Explicit var ys = from x in xs          where x.A > 1          select x; var zs = from y1 in ys          from y2 in ys.ShiftEventTime(_ => TimeSpan.FromSeconds(1))          select y1 + y2; var ys = from x in xs          where x.A > 1          select x; var zs = ys.Multicast(ys1 =>     from y1 in ys1     from y2 in ys1.ShiftEventTime(_ => TimeSpan.FromSeconds(1))     select y1 + y2; Notice the product translates an expression using implicit multicast into an expression using the explicit multicast operator. The user does not see this translation. Default window policies Only default window policies are supported in the new surface. Other policies can be simulated by using AlterEventLifetime. Before After xs.SnapshotWindow(     WindowInputPolicy.ClipToWindow,     SnapshotWindowInputPolicy.Clip) xs.SnapshotWindow() xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.PointAlignToWindowEnd) xs.TumblingWindow(     TimeSpan.FromSeconds(1)) xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.ClipToWindowEnd) Not supported … LeftAntiJoin Representation of LASJ as a correlated sub-query in the LINQ surface is problematic as the StreamInsight engine does not support correlated sub-queries (see discussion of SelectMany). The current syntax requires the introduction of an otherwise unsupported ‘IsEmpty()’ operator. As a result, the pattern is not discoverable and implies capabilities not present in the server. The direct representation of LASJ is used instead: Before After from x in xs where     (from y in ys     where x.A > y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, (x, y) => x.A > y.B) from x in xs where     (from y in ys     where x.A == y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, x => x.A, y => y.B) ApplyWithUnion The ApplyWithUnion methods have been deprecated since their signatures are redundant given the standard SelectMany overloads: Before After xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count()) xs.GroupBy(x => x.A).SelectMany(     gs =>     from win in gs.SnapshotWindow()     select win.Count()) xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count(), r => new { r.Key, Count = r.Payload }) from x in xs group x by x.A into gs from win in gs.SnapshotWindow() select new { gs.Key, Count = win.Count() } Alternate UDO syntax The representation of UDOs in the StreamInsight LINQ dialect confuses cardinalities. Based on the semantics of user-defined operators in StreamInsight, one would expect to construct queries in the following form: from win in xs.SnapshotWindow() from y in MyUdo(win) select y Instead, the UDO proxy method is referenced within a projection, and the (many) results returned by the user code are automatically flattened into a stream: from win in xs.SnapshotWindow() select MyUdo(win) The “many-or-one” confusion is exemplified by the following example that compiles but fails at runtime: from win in xs.SnapshotWindow() select MyUdo(win) + win.Count() The above query must fail because the UDO is in fact returning many values per window while the count aggregate is returning one. Original syntax New alternate syntax from win in xs.SnapshotWindow() select win.UdoProxy(1) from win in xs.SnapshotWindow() from y in win.UserDefinedOperator(() => new Udo(1)) select y -or- from win in xs.SnapshotWindow() from y in win.UdoMacro(1) select y Notice that this formulation also sidesteps the dynamic type pitfalls of the existing “proxy method” approach to UDOs, in which the type of the UDO implementation (TInput, TOuput) and the type of its constructor arguments (TConfig) need to align in a precise and non-obvious way with the argument and return types for the corresponding proxy method. UDSO syntax UDSO currently leverages the DataContractSerializer to clone initial state for logical instances of the user operator. Initial state will instead be described by an expression in the new LINQ surface. Before After xs.Scan(new Udso()) xs.Scan(() => new Udso()) Name changes ShiftEventTime => AlterEventStartTime: The alter event lifetime overload taking a new start time value has been renamed. CountByStartTimeWindow => CountWindow

• Proxying fake domain to a localhost port

  - by Trevor Burnham

  I'd like to do much the same thing described at Redirect Domain Name to Localhost for web app development purposes, but with the twist that I'd like requests to fakedomain.com:80 to be routed to localhost:8080, say, so that I don't have to actually use my development machine's port 80. I'd welcome answers that take the form of: Small changes to configuration files like /etc/hosts, and/or An easy-to-configure proxy server I could run Note: Pow takes the approach of setting a firewall rule to forward all incoming traffic on port 80 to port 20559. That may be an acceptable solution, but ideally, I'd like to forward only a specific domain + port combination.

• SEO strategy for h1, h2, h3 tags for list of items

  - by Theo G

  On a page on my website page I have a list of ALL the products on my site. This list is growing rapidly and I am wondering how to manage it from an SEO point of view. I am shortly adding a title to this section and giving it an H1 tag. Currently the name of each product in this list is not h1,2,3,4 its just styled text. However I was looking to make these h2,3,4. Questions: Is the use of h2,3,4 on these list items bad form as they should be used for content rather than all links? I am thinking of limiting this main list to only 8 items and using h2 tags for each name. Do you this this will have a negative or possible affect over all. I may create a piece of script which counts the first 8 items on the list. These 8 will get the h2, and any after that will get h3 (all styled the same). If I do add h tags should I put just on the name of the product or the outside of the a tag, therefore collecting all info. Has anyone been in a similar situation as this, and if so did they really see any significant difference?

• Data Archiving vs not

  - by Recursion

  For the sake of data integrity, is it wiser to archive your files or just leave them unarchived. No compression is being used. My thinking is that if you leave your files unarchived, if there is some form of corruption it will only hurt a smaller number of files. Though if you archive, lets say all of your documents, if there is even the slightest corruption, the entire archive is unrecoverable. So whats the best way to keep a clean file system, but not be subject to data corruption.

• What are the options for retraining formally as a software engineer?

  - by Matt Harrison

  I'm a self-taught programmer. I have a good undergraduate degree in Architecture (building, not software). I was always a science/maths kid and got consistency good grades in these subjects. However I became indecisive at undergraduate level and switched between Physics, Chemistry, Art and finally stuck with Architecture mainly out of the desperate need to finish any degree. As soon as I graduated, I ditched architecture and started writing code again professionally. I've been a programmer now for 3 years and I've progressed very quickly. I'm ambitious and I want to work for the top companies in this field at some point and I've realised I need a Computer Science education to be taken seriously (based on job ads for the big tech firms). I've applied for a few MSc programs in Computer Science but they've all rejected me because of my BA. It's just not an option for me to quit my job and go back and do another 3 year undergraduate degree in CS. I know I can study at this level because I've read most of the books on the reading lists for CS courses in the UK that I can find and I have this knowledge now, it's just I can't prove it on an application form. What options are available to me?

• Algorithmic problem - quickly finding all #'s where value %x is some given value

  - by Steve B.

  Problem I'm trying to solve, apologies in advance for the length: Given a large number of stored records, each with a unique (String) field S. I'd like to be able to find through an indexed query all records where Hash(S) % N == K for any arbitrary N, K (e.g. given a million strings, find all strings where HashCode(s) % 17 = 5. Is there some way of memoizing this so that we can quickly answer any question of this form without doing the % on every value? The motivation for this is a system of N distributed nodes, where each record has to be assigned to at least one node. The nodes are numbered 0 - (K-1) , and each node has to load up all of the records that match it's number: If we have 3 nodes Node 0 loads all records where Hash % 3 ==0 Node 1 loads all records where Hash % 3 ==1 Node 2 loads all records where Hash % 3 ==2 adding a 4th node, obviously all the assignments have to be recomputed - Node 0 loads all records where Hash % 4 ==0 ... etc I'd like to easily find these records through an indexed query without having to compute the mod individually. The best I've been able to come up with so far: If we take the prime factors of N (p1 * p2 * ... ) if N % M == I then p % M == I % p for all of N's prime factors e.g. 10 nodes : N % 10 == 6 then N % 2 = 0 == 6 %2 N % 5 = 1 == 6 %5 so storing an array of the "%" of N for the first "reasonable" number of primes for my data set should be helpful. For example in the above example we store the hash and the primes HASH PRIMES (array of %2, %3, %5, %7, ... ]) 16 [0 1 1 2 .. ] so looking for N%10 == 6 is equivalent to looking for all values where array[1]==1 and array[2] == 1. However, this breaks at the first prime larger than the highest number I'm storing in the factor table. Is there a better way?

• Tips about how to spread Object Oriented practices

  - by Augusto

  I work for a medium company that has around 250 developers. Unfortunately, lots of them are stuck in a procedural way of thinking and some teams constantly deliver big Transactional Script applications, when in fact the application contains rich logic. They also fail to manage the design dependencies, and end up with services which depend on another large number of services (a clean example of Big Ball of Mud). My question is: Can you suggest how to spread this type of knowledge? I know that the surface of the problem is that these applications have a poor architecture and design. Another issue is that there are some developers who are against writing any kind of test. A few things I'm doing to change this (but I'm either failing or the change is too small are) Running presentations about design principles (SOLID, clean code, etc). Workshops about TDD and BDD. Coaching teams (this includes using sonar, findbugs, jdepend and other tools). IDE & Refactoring talks. A few things I'm thinking to do in the future (but I'm concern that they might not be good) Form a team of OO evangelists, who disseminate an OO way of thinking in differet teams (these people would need to change teams every few months). Running design review sessions, to criticise the design and suggest improvements (even if the improvements are not done because of time constraints, I think this might be useful) . Something I found with the teams I coach, is that as soon as I leave them, they revert back to the old practices. I know I don't spend a lot of time with them, usually just one month. So whatever I'm doing, it doesn't stick. I'm sorry this question is spattered with frustration, but the alterative to write this was to hit my head on the wall until I pass out.
