• How do I backup my customer's data?

  - by marcamillion

  If you run a SaaS app, or work on one, I would love to hear from you. Where the safety and security of your customer's data is paramount, how do you secure it and back it up? I would love to know your main host (e.g. Heroku, Engine Yard, Rackspace, MediaTemple, etc.) and who you use for your backup. Be as detailed as possible - e.g. a quick overview of your service and the data you store (images for instance), what happens with the images when the user uploads them (e.g. they go to your Linode VPS, and posted to the site for them to see - then they are automatically sent to AWS or wherever, then once a week they are backed up to tape by the managed hosting provider, and you also back them up to your house/office). If you could also give some idea as to what the unit cost (per GB/per user/per month) of storage is - on average, I would really appreciate that. Getting ready to launch my app, and I would love to get some more perspective on the nitty gritty details involved. Thanks!

• Please help me decide if I should I change jobs [closed]

  - by KindaNewbie

  About me: I am very entrepreneurial and believe I would do well working solo as a consultant and possibly hiring help. I do want to do that at some point. I love to learn and a good challenge. Please help me make this decision! Current job (I am there for about 4 years): Pros: secure job good pay (I guess I am 80 percentile for my level/geographical area) large corporation - main business is not software excellent health insurance for low cost to me, pension, 401k matching, 6 weeks paid time off per year small dev team use of latest technologies (mostly WPF/silverlight) low supervision (I can do personal things all the time) I get to do a lot of moonlighting and my goal was to go solo full-time in a year or so. Cons: small team of non-professional devs 50% of my time I do things I don't enjoy projects are not meaningful to the organization If I left it wouldn't be too hard for them - business would resume as usual. Nobody besides my small team of 3 has any idea about software development whatsoever. Prospect job: Pros: small/agile software company same salary as current job same size dev team but all are very sharp (I would probably be the weakest of the team in the beginning) technology used is outside my comfort zone (latest cool web technolgies such as html5/jquery/...) - I am not a web dev and they know that. ton of learning opportunity Start-up - possibility of stock option/partial ownership of some sort Cons: Small office space - not able to do personal things as often (may be pro) No room for moonlighting less benefits (but salary can compensate for that)

• Remember way back when we had a free decompiler?

  - by Justin Jones

  I, like probably so many of the rest of you, was mortified when Reflector was sold to RedGate. I knew where it was going. Suddenly you had to install it instead of just download and run it. I had a deep down feeling that one of the most useful tools in my arsenal was about to become a corporate product and no longer belong to the world of free tools. Sure enough it did. For a while now I’ve limped by without my favorite decompiler. This was made a little easier by the fact that you can now debug into the .net framework, but I still missed Reflector. JetBrains, makers of the superawesome and well worth the cost ReSharper (no it’s not free) have made their own decompiler that is comparable with Reflector, and it’s free. It’s still a corporate product, and JetBrains isn’t exactly known for making free software, but for now we have an option back on the table until some other industrious developer makes the next Reflector. dotPeek can be downloaded here.  http://www.jetbrains.com/decompiler/

• Why is the use of abstractions (such as LINQ) so taboo?

  - by Matthew Patrick Cashatt

  I am an independent contractor and, as such, I interview 3-4 times a year for new gigs. I am in the midst of that cycle now and got turned down for an opportunity even though I felt like the interview went well. The same thing has happened to me a couple of times this year. Now, I am not a perfect guy and I don't expect to be a good fit for every organization. That said, my batting average is lower than usual so I politely asked my last interviewer for some constructive feedback, and he delivered! The main thing, according to the interviewer, was that I seemed to lean too much towards the use of abstractions (such as LINQ) rather than towards lower-level, organically grown algorithms. On the surface, this makes sense--in fact, it made the other rejections make sense too because I blabbed about LINQ in those interviews as well and it didn't seem that the interviewers knew much about LINQ (even though they were .NET guys). So now I am left with this question: If we are supposed to be "standing on the shoulders of giants" and using abstractions that are available to us (like LINQ), then why do some folks consider it so taboo? Doesn't it make sense to pull code "off the shelf" if it accomplishes the same goals without extra cost? It would seem to me that LINQ, even if it is an abstraction, is simply an abstraction of all the same algorithms one would write to accomplish exactly the same end. Only a performance test could tell you if your custom approach was better, but if something like LINQ met the requirements, why bother writing your own classes in the first place? I don't mean to focus on LINQ here. I am sure that the JAVA world has something comparable, I just would like to know why some folks get so uncomfortable with the idea of using an abstraction that they themselves did not write. UPDATE As Euphoric pointed out, there isn't anything comparable to LINQ in the Java world. So, if you are developing on the .NET stack, why not always try and make use of it? Is it possible that people just don't fully understand what it does?

• High quality/performance shared hosting (in northern Europe)

  - by Bente

  I work as a web developer on almost all levels. However, my typical customer is a 1-5 guys running some sort of consulting business. They have (or want) a web page with some kind of CMS so the can perform most (or all) editing themselves. I normally opt for Concrete5 as my default CMS because it's the most user friendly (and free) CMS I have found. My good recurring customers I host on my own server as a service, but I need a good host for the customers where I want to deliver a product and not be responsible for whatever may happen in the future. However, I still struggle with hosting! Experience shows that the typical ~1$ shared hosting is waaay to slow to run concrete5 smoothly, and a VPS is out of the question because I don't want to maintain it. So, where can I find as fast (from northern Europe), reliable, shared host where I can put a site and don't have to worry about the server going down or being unmaintained. I expect this should cost around $10-$20 but I'm open to all kinds of suggestions because different customers have different budgets.

• How to represent a graph with multiple edges allowed between nodes and edges that can selectively disappear

  - by Pops

  I'm trying to figure out what sort of data structure to use for modeling some hypothetical, idealized network usage. In my scenario, a number of users who are hostile to each other are all trying to form networks of computers where all potential connections are known. The computers that one user needs to connect may not be the same as the ones another user needs to connect, though; user 1 might need to connect computers A, B and D while user 2 might need to connect computers B, C and E. Image generated with the help of NCTM Graph Creator I think the core of this is going to be an undirected cyclic graph, with nodes representing computers and edges representing Ethernet cables. However, due to the nature of the scenario, there are a few uncommon features that rule out adjacency lists and adjacency matrices (at least, without non-trivial modifications): edges can become restricted-use; that is, if one user acquires a given network connection, no other user may use that connection in the example, the green user cannot possibly connect to computer A, but the red user has connected B to E despite not having a direct link between them in some cases, a given pair of nodes will be connected by more than one edge in the example, there are two independent cables running from D to E, so the green and blue users were both able to connect those machines directly; however, red can no longer make such a connection if two computers are connected by more than one cable, each user may own no more than one of those cables I'll need to do several operations on this graph, such as: determining whether any particular pair of computers is connected for a given user identifying the optimal path for a given user to connect target computers identifying the highest-latency computer connection for a given user (i.e. longest path without branching) My first thought was to simply create a collection of all of the edges, but that's terrible for searching. The best thing I can think to do now is to modify an adjacency list so that each item in the list contains not only the edge length but also its cost and current owner. Is this a sensible approach? Assuming space is not a concern, would it be reasonable to create multiple copies of the graph (one for each user) rather than a single graph?

• Which approach is the most maintainable?

  - by 2rs2ts

  When creating a product which will inherently suffer from regression due to OS updates, which of these is the preferable approach when trying to reduce maintenance cost and the likelihood of needing refactoring, when considering the task of interpreting system state and settings for a lay user? Delegate the responsibility of interpreting the results of inspecting the system to the modules which perform these tasks, or, Separate the concerns of interpretation and inspection into two modules? The first obviously creates a blob in which a lot of code would be verbose, redundant, and hard to grok; the second creates a strong coupling in which the interpretation module essentially has to know what it expects from inspection routines and will have to adapt to changes to the OS just as much as the inspection will. I would normally choose the second option for the separation of concerns, foreseeing the possibility that inspection routines could be re-used, but a developer updating the product to deal with a new OS feature or something would have to not only write an inspection routine but also write an interpretation routine and link the two correctly - and it gets worse for a developer who has to change which inspection routines are used to get a certain system setting, or worse yet, has to fix an inspection routine which broke after an OS patch. I wonder, is it better to have to patch one package a lot or two packages, each somewhat less so?

• IIM Calcutta &ndash; EPBM14 &ndash; Campus Visit &ndash; Day 3 &ndash; Kali Temple, IS &amp; Strateg

  - by Ram Shankar Yadav

  Hey folks~ Today was one of the most happening day for us, we got up @ 5 AM and did our daily morning chores and left hostel room by 5:35 AM. So why we got up so early??? Okay we planned a visit to Kali Temple at KaliGhat! So till everyone assembles, we took few pics on the Lake Deck. We left Joka campus at 6 AM and reached Kali temple at 6:50 AM. Kali temple is very famous in Kolkata, but the frankly speaking it’s one of the most unorganised one for sure~! After darshan, we got back into our Taxis and headed for breakfast at Gupta Brothers Restaurant. We enjoyed “doodh-jalebi”, “Kachori-sabzi” and rasogullas there~! While coming back, one of our Taxi’s excel broken and we waited for the first to come back and take us to Campus. After coming back to campus, we attended our sessions on IS & Strategy on ITC eChaupal and Transactional Cost and Vertical Integration(TCVI). After our classed we had “Dinner Party” organised by IIMC, and we enjoyed it thoroughly, and many of us took this as an opportunity to share our biz card and talk to Professors. Overall it’s was a rocking day!! Stay tuned for more… Cheers, ram :)   Photo Album :

• Disaster Recovery Example

  Previously, I use to work for a small internet company that sells dental plans online. Our primary focus concerning disaster prevention and recovery is on our corporate website and private intranet site. We had a multiphase disaster recovery plan that includes data redundancy, load balancing, and off-site monitoring. Data redundancy is a key aspect of our disaster recovery plan. The first phase of this is to replicate our data to multiple database servers and schedule daily backups of the databases that are stored off site. The next phase is the file replication of data amongst our web servers that are also backed up daily by our collocation. In addition to the files located on the server, files are also stored locally on development machines, and again backed up using version control software. Load balancing is another key aspect of our disaster recovery plan. Load balancing offers many benefits for our system, better performance, load distribution and increased availability. With our servers behind a load balancer our system has the ability to accept multiple requests simultaneously because the load is split between multiple servers. Plus if one server is slow or experiencing a failure the traffic is diverted amongst the other servers connected to the load balancer allowing the server to get back online. The final key to our disaster recovery plan is off-site monitoring that notifies all IT staff of any outages or errors on the main website encountered by the monitor. Messages are sent by email, voicemail, and SMS. According to Disasterrecovery.org, disaster recovery planning is the way companies successfully manage crises with minimal cost and effort and maximum speed compared to others that are forced to make decision out of desperation when disasters occur. In addition Sun Guard stated in 2009 that the first step in disaster recovery planning is to analyze company risks and factor in fixed costs for things like hardware, software, staffing and utilities, as well as indirect costs, such as floor space, power protection, physical and information security, and management. Also availability requirements need to be determined per application and system as well as the strategies for recovery.

• Not All iPhone 5 and Galaxy SIII in Some Markets #UX #mobile #BBC #L10n

  - by ultan o'broin

  The BBC World Service provides news content to more people across the globe, and has launched a series of new apps tailored for Nokia devices, allowing mobile owners to receive news updates in 11 different languages. So, not everyone using an iPhone 5 or Samsung Galaxy SIII then? hardly surprising given one of these devices could cost you a large chunk of your annual income in some countries! The story is a reminder of taking into account local market requirements and using a toolkit to develop solutions for them. The article tells us The BBC World Service apps will feature content from the following BBC websites: BBC Arabic, BBC Brasil (in Portuguese), BBC Chinese, BBC Hindi, BBC Indonesia, BBC Mundo (in Spanish), BBC Russian, BBC Turkce, BBC Ukrainian, BBC Urdu and BBC Vietnamese. Users of the Chinese, Indonesian and Arabic apps will receive news content but will also be able to listen to radio bulletins.It’s a big move for the BBC, particularly as Nokia has sold more than 675 million Series 40 handsets to date. While the company’s smartphone sales dwindle, its feature phone business has continued to prop up its balance sheet. Ah, feature phones. Remember them? You should! Don't forget that Oracle Application Development Framework solution for feature phones too: Mobile Browser. So, don't ignore a huge market segment and opportunity to grow your business by disregarding feature phones when Oracle makes it easy  for you to develop mobile solutions for a full range of devices and users! Let's remind ourselves of the different mobile toolkit solutions offered by Oracle or coming soon that makes meeting the users of global content possible. Mobile Development with ADF Mobile (Oracle makes no contractual claims about development, release, and timing of future products.) All that said, check out where the next big markets for mobile apps is coming from in my post on Blogos: Where Will The Next 10 Million Apps Come From? BRIC to MIST.

• HP G42 Ubuntu live cd failure

  - by Jon

  Ok, I have tried every option under the sun. I have surfed through the internet for a good 3 hours straight and to no effect. I installed ubuntu on my HP G42 laptop, it worked fine, then when I tried installing the standard after installation updates my wifi failed. In my attempt to fix my wi-fi I rebooted my laptop, when I rebooted I was stuck on a black screen with nothing that I tried to fix it helping the situation. So I then tried to fix it by reinstalling Ubuntu. When I attempted to boot into the live ccd it failed leaving with the now familar black screen. After numerous attempts using instructions from live cd and instal failure blank screen... page and replacing my hard drive at a cost of $65 I am coming here for help. As for the actual DVD that I tried installing ubuntu from it was able to install ubuntu on a mac just fine after my issues on the HP. After installing the hard drive I loaded up windows just fine but I don't want windows I want ubuntu, can you please provide instructions on how to install ubuntu?

• Configuration Tips for better Performance with ADF Mobile Apps

  - by SRINI INDLA

  Some tips to keep in mind to make sure ADF Mobile application's performance is optimal: 1. Select release mode in deployment profile. This is perhaps the most important thing to remember to ensure best performance for ADF Mobile Apps. Selecting this option causes the deployer to package optimized JVM and minified JS libs with the mobile app there by significantly improving the over all performance of the application. 2. For iOS you do not need to do anything else other than selecting  release mode in deploy profile. However, on Android you have to create a keystore and configure it in JDev --> Tools --> Preferences --> ADF Mobile --> Platforms : Android as shown in the snapshot below 3. Steps for generating the Keystore for Android using keytool :  4. Logging level setting in logging.properties: Make sure the log level is set to SEVERE for both framework logger as well as the application logger as follows oracle.adfmf.framework.level=SEVERE oracle.adfmf.application.level=SEVERE 5. When using SOAP WebServices with WebService Data Control make sure you select the option to copy the WSDL. This will cause the JDev to download the WSDL and all the XSDs referenced by the WSDL from the server at design time and package them with the application during deployment. This way the application does not incur the cost of downloading these resources at run time from the device.

• Architecture : am I doing things right?

  - by Jeremy D

  I'm trying to use a '~classic' layered arch using .NET and Entity Framework. We are starting from a legacy database which is a little bit crappy: Inconsistent naming Unneeded views (view referencing other views, select * views etc...) Aggregated columns Potatoes and Carrots in the same table etc... So I ended with fully isolating my database structure from my domain model. To do so EF entities are hidden from presentation layer. The goal is to permit an easier database refactoring while lowering the impact of it on applications. I'm now facing a lot of challenges and I'm starting to ask myself if I'm doing things right. My Domain Model is highly volatile, it keeps evolving with apps as new fields needs are arising. Complexity of it keeps raising and class it contains start to get a lot of properties. Creating include strategy and reprojecting to EF is very tricky (my domain objects don't have any kind of lazy/eager loading relationship properties): DomainInclude<Domain.Model.Bar>.Include("Customers").Include("Customers.Friends") // To... IFooContext.Bars.Include(...).Include(...).Where(...) Some framework are raping the isolation levels (Devexpress Grids which needs either XPO or IQueryable for filtering and paging large data sets) I'm starting to ask myself if : the isolation of EF auto-generated entities is an unneeded cost. I should allow frameworks to hit IQueryable? Slow slope to hell? (it's really hard to isolate DevExpress framework, any successful experience?) the high volatility of my domain model is normal? Did you have similar difficulties? Any advice based on experience?

• How to Reap Anticipated ROI in Large-Scale Capital Projects

  - by Sylvie MacKenzie, PMP

  Only a small fraction of companies in asset-intensive industries reliably achieve expected ROI for major capital projects 90 percent of the time, according to a new industry study. In addition, 12 percent of companies see expected ROIs in less than half of their capital projects. The problem: no matter how sophisticated and far-reaching the planning processes are, many organizations struggle to manage risks or reap the expected value from major capital investments. The data is part of the larger survey of companies in oil and gas, mining and metals, chemicals, and utilities industries. The results appear in Prepare for the Unexpected: Investment Planning in Asset-Intensive Industries, a comprehensive new report sponsored by Oracle and developed by the Economist Intelligence Unit. Analysts say the shortcomings in large-scale, long-duration capital-investments projects often stem from immature capital-planning processes. The poor decisions that result can lead to significant financial losses and disappointing project benefits, which are particularly harmful to organizations during economic downturns. The report highlights three other important findings. Teaming the right data and people doesn’t guarantee that ROI goals will be achieved. Despite involving cross-functional teams and looking at all the pertinent data, executives are still failing to identify risks and deliver bottom-line results on capital projects. Effective processes are the missing link. Project-planning processes are weakest when it comes to risk management and predicting costs and ROI. Organizations participating in the study said they fail to achieve expected ROI because they regularly experience unexpected events that derail schedules and inflate budgets. But executives believe that using more-robust risk management and project planning strategies will help avoid delays, improve ROI, and more accurately predict the long-term cost of initiatives. Planning for unexpected events is a key to success. External factors, such as changing market conditions and evolving government policies are difficult to forecast precisely, so organizations need to build flexibility into project plans to make it easier to adapt to the changes. The report outlines a series of steps executives can take to address these shortcomings and improve their capital-planning processes. Read the full report or take the benchmarking survey and find out how your organization compares.

• How is determined an impact of a requirement change on the existing code?

  - by MainMa

  Hi, How companies working on large projects evaluate an impact of a single modification on an existing code? Since my question is probably not very clear, here's an example: Let's take a sample business application which deals with tasks. In the database, each task has a state, 0 being "Pending", ... 5 - "Finished". A new requirement adds a new state, between 2nd and 3rd one. It means that: A constraint on the values 1 - 5 in the database must be changed, Business layer and code contracts must be changed to add a new state, Data access layer must be changed to take in account that, for example the state StateReady is now 6 instead of 5, etc. The application must implement a new state visually, add new controls for it, new localized strings for tool-tips, etc. When an application is written recently by one developer, it's more or less easy to predict every change to do. On the other hand, when an application was written for years by many people, no single person can anticipate every change immediately, without any investigation. So since this situation (such changes in requirements) is very frequent, I imagine there are already some clever techniques and ways to predict the impact. Is there any? Do you know any books which deal about this subject? Note: my question is not related to How do you deal with changing requirements? question. In fact, I'm not interested in evaluating the cost of a change, but rather the way to predict the parts of an application which will be concerned by the change. What will be those changes and how difficult they are really doesn't matter in my question.

• How to optimize calls to multiple APIs at once and return as one set?

  - by Martin

  I have a web app that searches across 2 APIs right now. I have my own Restful web service that I call, and it does all the work on the backend to asynchronously call the 2 APIs and concatenate them into one result set for my web app to use. I want to scale this out and add as many other APIs as I can (currently looking at about 10 more). But as I add APIs, the call to my service gets (potentially) slower and more complex. How do I handle one API not responding ... and other issues that arise? What would be the best way to approach this? Should I create a service call for each API, that way each one is independent and not coupled to all the other calls? Is there a way on the backend to handle the multiple API calls without all the extra complexity it adds? If I go the route of a service call per API, now my client code gets more complex (and I have a lot of clients)? And it's more work for the client, and since I have mobile apps, it will cost the client more data usage. If I go one service call, is there a way to set up some sort of connection so I can return data as I get it, in case one service call hangs?

• What should I recommend a small company looking for C# developers

  - by Coder

  Here is the issue. I am a senior developer, and one of the start-ups I designed the system (management system/database/web) a long time ago, have grown and need software updates. I have left their system to another developer long time ago, but apparently he has left the job, and so they are asking me if I can suggest them where to find a new one. The problem is that the company has no clue that the IT is not cheap. They expect multiple features to be added for 40$, so that's an issue. Actually one of the reasons why I left the project when I did. Lots of expectations, little pay, also I know those people outside work, so I decided to avoided stressing the nonwork-relationships and left the project gracefully. Today they asked me for an advice, and I told them that the feature list they want is probably going to cost some if they'll get a senior developer for the job. So I guess their best bet is to find someone who loves coding and has just finished the school. Which would give someone a chance to code for money which is good for a student, and at the same time, allow the student to get some hands on experience. Then again, the system is not exactly 20 line console program, there is an MSSQL database, ASP.NET web page and content management system with all the AJAX stuff and some other things. So student straight out of school could have some problems with that. But, I thought about the issue some more, and I think that junior developer is a tricky deal, without mentoring, he can either screw up royally, or just do what's asked. Also, it seems no one is coming to interviews at all, which is weird, or maybe not. What should I suggest them?

• How to determine the amount to spend per phrase on Adwords research?

  - by Anonymous -

  My company would like to start a PPC advertising campaign. Whilst I understand the concept and how to set everything up from a technical point of view, this is something I've never done before. Logically, we'd like to test out a wide range of keywords that we think would lead to conversions, which we've put together through brainstorming and with some help from Google's External Keyword Tool. Sub-question whilst I remember - am I correct in thinking that in Google's keyword tool, keywords that we think will perform well that have a low competition yet high monthly searches are good since there will be less advertisers, meaning our bid per click will be less? Is there a common benchmark or process of doing a round of tests with keywords? Should we wait for 100 clicks on each keyword, see which ones have lead to the most sales (or rather, sales that are sustainable with the cost per click of that keyword), then drop the ones which aren't converting and put that budget onto the converting keywords? We realistically have a few hundred keywords/phrases we would like to test, but spending $100 per keyword/phrase is going to work out as quite an expensive test. It would be nice to be able to spend $5-10 per phrase, but I don't think the sample size would be great enough to determine anything usefully reliable. Another approach might be to setup all the keywords, and those that bring the most sales within x hours/days would be the ones we use. What is the common procedure with things like this? I know there are a plethora of companies that specialize in exactly this, but this is something we anticipate doing a lot in the future, so it would make sense to do it in house if at all possible.

• Cheap ways to do scaling ops in shader?

  - by Nick Wiggill

  I've got an extensive world terrain that uses vec3 for the vertex position attribute. That's good, because the terrain has endless gradations due to the use of floating point. But I'm thinking about how to reduce the amount of data uploaded to the GPU. For my terrain, which uses discrete / grid-based vertex positions in x and z, it's pretty clear that I can replace my vec3s (floats, really) with shorts, halving the per-vertex position attribute cost from 12 bytes each to 6 bytes. Considering I've got little enough other vertex data, and an enormous amount of terrain data to push into the world, it's a major gain. Currently in my code, one unit in GLSL shaders is equal to 1m in the world. I like that scale. If I move over to using shorts, though, I won't be able to use the same scale, as I would then have a very blocky world where every step in height is an entire metre. So I see these potential solutions to scale the positional data correctly once it arrives at the vertex shader stage: Use 10:1 scaling, i.e. 1 short unit = 1 decimetre in CPU-side code. Do a division by 10 in the vertex shader to scale incoming decimetre values back to metres. Arbirary (non-PoT) divisions tend to be slow, however. Use (some-power-of-two):1 scaling (eg. 8:1), which enables the use of a bitshift (eg. val >> 3) to do the division... not sure how performant this is in shaders, though. Not as intuitive to read values, but possibly quite a bit faster than div by a non-PoT value. Use a texture as lookup table. I've heard that this is really fast. Or whatever solutions others can offer to achieve the same results -- minimal vertex data with sensible scaling.

• Dedicated Servers: Is one better then two for LAMP pseudo HA setup? [closed]

  - by bikedorkseattle

  Possible Duplicate: How to find web hosting that meets my requirements? I know there are zillions of commentary about hosting out there, but I haven't read much about this. Our current well known host is having too many problems, the hardware we are on it subpar, and I'm ready to leave. A day of downtime can cost as much as our monthly hosting bill. A month of bad performance is just killing us right now, user and google wise. I'm wondering about running two dedicated boxes for LAMP, one running as the primary Nginx/Apache (proxy pass), and the other as the MySQL box. Running a single box scares the bejesus out of me because who knows how long it will take anyone to fix a raid card or whatever. The idea is to set this up using some sort of failover system using pacemaker and heartbeat. If one server goes down the other can take over for the other running both web and db. There are some good articles over at Linode about this. I have a few DBs that are 1GB+ and would like to load them into memory. Because of this, I'm shying away from a Linode HA setup because for the price I could do it with two dedicated like I described. Am I mad or an idiot? What are people out there doing for pseodu high availability good performance setups under $400/month? I'm a webmaster; I do a lot of things none of it that well :)

• The advantages & disadvantages to be had from using a Web Framework?

  - by JHarley1

  Hello, This question is focused on extracting the advantages and disadvantages of using Web based Frameworks: such as Cake PHP, Zend, jQuery, ASP.NET). This question is completely language agnostic. Let me start with the notion of "Standing on the shoulders of Giants". Advantages: Empowers Developers - by taking features that would have previously have taken 100's of lines of code and compressing them into one simple function call empowers developers to integrate more complex features into their Web Sites. Allow for Quicker development of applications - this is very relevant for people that need websites created in a very small window (has anyone any examples of this?) Lower Costs - allows programmers to pass cost savings onto the customer, a whole new range of customers generated that wanted a website but previously could not afford the higher development costs. Disadvantages: Lost Understanding - by relying on the features of a framework a developer is in danger of loosing understanding on how things work (underneath the hood). The configuration cliff - once you go further than the configuration of your framework your productivity drops right off, it can be difficult to implement features outside of a frameworks configuration. Developer tramlines - you (the developer) has to do things the way that the developer want you to do things. Security issues - giving people these tools to develop professional looking websites fast is a potential risk, people can quickly create professional looking websites for fraudulent companies. I wonder what people make of my points, and whether any body disagrees with them? Also if people have additional points I would be grateful. Many Thanks, J
