  • Calculating a total cost in Python

    - by Sérgio Lourenço
    I'm trying to create a trip planner in python, but after I defined all the functions I'm not able to call and calculate them in the last function tripCost(). In tripCost, I want to put the days and travel destination (city) and the program runs the functions and gives me the exact result of all the 3 functions previously defined. Code: def hotelCost(): days = raw_input ("How many nights will you stay at the hotel?") total = 140 * int(days) print "The total cost is",total,"dollars" def planeRideCost(): city = raw_input ("Wich city will you travel to\n") if city == 'Charlotte': return "The cost is 183$" elif city == 'Tampa': return "The cost is 220$" elif city == 'Pittsburgh': return "The cost is 222$" elif city == 'Los Angeles': return "The cost is 475$" else: return "That's not a valid destination" def rentalCarCost(): rental_days = raw_input ("How many days will you rent the car\n") discount_3 = 40 * int(rental_days) * 0.2 discount_7 = 40 * int(rental_days) * 0.5 total_rent3 = 40 * int(rental_days) - discount_3 total_rent7 = 40 * int(rental_days) - discount_7 cost_day = 40 * int(rental_days) if int(rental_days) >= 3: print "The total cost is", total_rent3, "dollars" elif int(rental_days) >= 7: print "The total cost is", total_rent7, "dollars" else: print "The total cost is", cost_day, "dollars" def tripCost(): travel_city = raw_input ("What's our destination\n") days_travel = raw_input ("\nHow many days will you stay\n") total_trip_cost = hotelCost(int(day_travel)) + planeRideCost (str(travel_city)) + rentalCost (int(days_travel)) return "The total cost with the trip is", total_trip_cost tripCost()

  • proper concurrent users estimation case studies

    - by golemwashere
    I've been asked to size a web architecture for an excessive number of concurrent users ( hundreds of thousands ). I'm having a hard time convincing these people that unless you are in the top 5 of your country websites it's quite hard to hit those numbers. Can anyone provide some real world case studies providing stats for total / concurrent users explaining what is the usual ratio between total vs concurrent?

  • How to do a cost-benefit analysis for platform-level features?

    - by Callister Park
    I work on a development team that works closely with Product Managers. There is mutual agreement between the developers and Product Managers that there should be a business case behind every feature the development team builds. My question is, what is an effective way to make a business case for platform-level features that have higher up front cost but will provide long term benefits? For example, the development team would like to implement a plug-in framework. There is the higher up-front cost to implement a plug-in framework but delivering the subsequent features as plug-ins will be cheaper in the long run. This is obvious to everyone including the Product Managers. Is there a standard/simple way to express the cost-benefits? Is there a simple way to visualize it with a graph?

  • Best criteria for choosing a DNS provider : Redundancy, Locations, Cost, IPV6, Reliability

    - by antoinet
    What criteria should I use to choose a good DNS provider? Redundancy - Your DNS service should use at least 4 nameservers. You should also check for the use of anycast servers such as Amazon Route 53 and dyn.com services. Worldwide server location - Servers shall be located worldwide, not just in one country! Ipv6 support - It shall be possible to declare an AAAA entry to your server if it supports IPV6 Cost is of course an issue. Some service are free, Amazon Route 53 seems quite cheap. Reliability : SLA is also important, it demonstrate that reliability is measured. Your dns provider shall then state for a refund in case a failure is encountered. Anything else? For reference, a couple of links for more information: http://serverfault.com/questions/216330/why-should-i-use-amazon-route-53-over-my-registrars-dns-servers http://aws.amazon.com/route53/ http://dyn.com/dns/

  • Free or Low Cost Web Hosting for Small Website [duplicate]

    - by etangins
    This question already has an answer here: How to find web hosting that meets my requirements? 5 answers I have a small website (between 2000 and 10000) page-views a day. I'm looking for a free or low cost web host. I tried 50webs.com but their server breaks down. So as not to cause debate, I am also just looking for links to good information sources for web hosting if just finding a good web host is too general. I currently only use HTML, CSS, and JavaScript though I'm considering learning PhP and other more advanced languages to step up my game.

  • The cost of longer delay between development and QA

    - by Neil N
    At my current position, QA has become a bottleneck. We have had the unfortunate occurence of features being held out of the current build so that QA could finish testing. This means features that are done being developed may not get tested for 2-3 weeks after the developer has already moved on. With dev moving faster thean QA, this time gap is only going to get bigger. I keep flipping through my copy of Code Compelte, looking for a "Hard Data" snippet that shows the cost of fixing defects grows exponentially the longer it exists. Can someone point me to some studies that back up this concept? I am trying to convince the powers that be that the QA bottleneck is a lot more costly than they think.

  • The practical cost of swapping effects

    - by sebf
    I use XNA for my projects and on those forums I sometimes see references to the fact that swapping an effect for a mesh has a relatively high cost, which surprises me as I thought to swap an effect was simply a case of copying the replacement shader program to the GPU along with appropriate parameters. I wondered if someone could explain exactly what is costly about this process? And put, if possible, 'relatively' into context? For example say I wanted to use a short shader to help with picking, I would: Change the effect on every object, calculting a unique color to identify it and providing it to the shader. Draw all the objects to a render target in memory. Get the color from the target and use it to look up the selected object. What portion of the total time taken to complete that process would be spent swapping the shaders? My instincts would say that rendering the scene again, no matter how simple the shader, would be an order of magnitude slower than any other part of the process so why all the concern over effects?

  • Any significant performance cost to using BlendState.Premultiplied?

    - by Donutz
    Normally I guess you'd use BlendState.AlphaBlend because normally when you load your textures through the pipeline they're already premultiplied. However, if you're loading textures at runtime from PNGs or some such, you have to loop through the pixels and premultiply them, which can take a long time if you've got a lot of textures to load. So it looks (haven't tried it) like using BlendState.Premultiplied instead of BlendState.AlphaBlend should handle non-premultiplied textures and produce the same visual result, without all the startup costs. I have to wonder if there's a non-obvious cost to doing this, like a huge drop in performance or something. Anyone know?

  • Cost of maintenance depending on paradigms

    - by Anto
    Is there any data on which paradigms allow for code which is easier/cheaper to maintain? Certainly, independantly of the chosen paradigm, good design is cheaper to maintain than bad, but there should probably be major differences coming only from the paradigm choice. Unstructured programming, for instance, generates very messy code (spaghetti code) which is expensive to maintain. In object oriented programming, implementation details are hidden and thus it should be pretty cheap to change those. In functional programming, there are no side effects, thus there is lesser risk of introducing bugs during maintainance, which should be cheaper. Is there any data on which paradigms are the most cost-efficient when coming down to maintenance? If no such data exists, what is your take on the question?

  • Cloud computing cost savings for large enterprise

    - by user13817
    I'm trying to understand whether cloud computing is meant for small to medium sized companies OR also for large companies. Imagine a website with a very large user base. The storage and bandwidth demands as well as the number of database transactions are incredibly high. The website might be hosting videos, music, images, etc. that keep the demands high. Does it make sense to be in the cloud when you know you need huge volumes of storage, bandwidth, and GET,PUT,etc. requests? (Each of these variables costs money in the cloud) OR does it make sense to build your own infrastructure? I can see the cost savings of cloud computing if you are a small business, but if you were aiming at the next big thing on the Internet, I can't quite see the benefits.

  • Cost of Web Server that hosted and delivered text only

    - by slandau
    We are developing an application that needs a web server to interact with the two (or more) entities involved. They will not ever see anything on the web, but the server is required for the transfer of data between them. It's sort of a holding point. Now, the only thing the server is going to be holding is textual data. The two entities are going to be doing the work with the data. I was wondering what the cost of this type of server would be. Since it would be JUST a database with no front end, would it make sense to employ a service through Amazon or Google that just holds data for me to access instead of buying a server and making my own database? The amount of data can grow very large however it's only text, and all data over a day old will be deleted for the most part every day. Thanks!

  • Windows Azure VMs - New "Stopped" VM Options Provide Cost-effective Flexibility for On-Demand Workloads

    - by KeithMayer
    Originally posted on: http://geekswithblogs.net/KeithMayer/archive/2013/06/22/windows-azure-vms---new-stopped-vm-options-provide-cost-effective.aspxDidn’t make it to TechEd this year? Don’t worry!  This month, we’ll be releasing a new article series that highlights the Best of TechEd announcements and technical information for IT Pros.  Today’s article focuses on a new, much-heralded enhancement to Windows Azure Infrastructure Services to make it more cost-effective for spinning VMs up and down on-demand on the Windows Azure cloud platform. NEW! VMs that are shutdown from the Windows Azure Management Portal will no longer continue to accumulate compute charges while stopped! Previous to this enhancement being available, the Azure platform maintained fabric resource reservations for VMs, even in a shutdown state, to ensure consistent resource availability when starting those VMs in the future.  And, this meant that VMs had to be exported and completely deprovisioned when not in use to avoid compute charges. In this article, I'll provide more details on the scenarios that this enhancement best fits, and I'll also review the new options and considerations that we now have for performing safe shutdowns of Windows Azure VMs. Which scenarios does the new enhancement best fit? Being able to easily shutdown VMs from the Windows Azure Management Portal without continued compute charges is a great enhancement for certain cloud use cases, such as: On-demand dev/test/lab environments - Freely start and stop lab VMs so that they are only accumulating compute charges when being actively used.  "Bursting" load-balanced web applications - Provision a number of load-balanced VMs, but keep the minimum number of VMs running to support "normal" loads. Easily start-up the remaining VMs only when needed to support peak loads. Disaster Recovery - Start-up "cold" VMs when needed to recover from disaster scenarios. BUT ... there is a consideration to keep in mind when using the Windows Azure Management Portal to shutdown VMs: although performing a VM shutdown via the Windows Azure Management Portal causes that VM to no longer accumulate compute charges, it also deallocates the VM from fabric resources to which it was previously assigned.  These fabric resources include compute resources such as virtual CPU cores and memory, as well as network resources, such as IP addresses.  This means that when the VM is later started after being shutdown from the portal, the VM could be assigned a different IP address or placed on a different compute node within the fabric. In some cases, you may want to shutdown VMs using the old approach, where fabric resource assignments are maintained while the VM is in a shutdown state.  Specifically, you may wish to do this when temporarily shutting down or restarting a "7x24" VM as part of a maintenance activity.  Good news - you can still revert back to the old VM shutdown behavior when necessary by using the alternate VM shutdown approaches listed below.  Let's walk through each approach for performing a VM Shutdown action on Windows Azure so that we can understand the benefits and considerations of each... How many ways can I shutdown a VM? In Windows Azure Infrastructure Services, there's three general ways that can be used to safely shutdown VMs: Shutdown VM via Windows Azure Management Portal Shutdown Guest Operating System inside the VM Stop VM via Windows PowerShell using Windows Azure PowerShell Module Although each of these options performs a safe shutdown of the guest operation system and the VM itself, each option handles the VM shutdown end state differently. Shutdown VM via Windows Azure Management Portal When clicking the Shutdown button at the bottom of the Virtual Machines page in the Windows Azure Management Portal, the VM is safely shutdown and "deallocated" from fabric resources.  Shutdown button on Virtual Machines page in Windows Azure Management Portal  When the shutdown process completes, the VM will be shown on the Virtual Machines page with a "Stopped ( Deallocated )" status as shown in the figure below. Virtual Machine in a "Stopped (Deallocated)" Status "Deallocated" means that the VM configuration is no longer being actively associated with fabric resources, such as virtual CPUs, memory and networks. In this state, the VM will not continue to allocate compute charges, but since fabric resources are deallocated, the VM could receive a different internal IP address ( called "Dynamic IPs" or "DIPs" in Windows Azure ) the next time it is started.  TIP: If you are leveraging this shutdown option and consistency of DIPs is important to applications running inside your VMs, you should consider using virtual networks with your VMs.  Virtual networks permit you to assign a specific IP Address Space for use with VMs that are assigned to that virtual network.  As long as you start VMs in the same order in which they were originally provisioned, each VM should be reassigned the same DIP that it was previously using. What about consistency of External IP Addresses? Great question! External IP addresses ( called "Virtual IPs" or "VIPs" in Windows Azure ) are associated with the cloud service in which one or more Windows Azure VMs are running.  As long as at least 1 VM inside a cloud service remains in a "Running" state, the VIP assigned to a cloud service will be preserved.  If all VMs inside a cloud service are in a "Stopped ( Deallocated )" status, then the cloud service may receive a different VIP when VMs are next restarted. TIP: If consistency of VIPs is important for the cloud services in which you are running VMs, consider keeping one VM inside each cloud service in the alternate VM shutdown state listed below to preserve the VIP associated with the cloud service. Shutdown Guest Operating System inside the VM When performing a Guest OS shutdown or restart ( ie., a shutdown or restart operation initiated from the Guest OS running inside the VM ), the VM configuration will not be deallocated from fabric resources. In the figure below, the VM has been shutdown from within the Guest OS and is shown with a "Stopped" VM status rather than the "Stopped ( Deallocated )" VM status that was shown in the previous figure. Note that it may require a few minutes for the Windows Azure Management Portal to reflect that the VM is in a "Stopped" state in this scenario, because we are performing an OS shutdown inside the VM rather than through an Azure management endpoint. Virtual Machine in a "Stopped" Status VMs shown in a "Stopped" status will continue to accumulate compute charges, because fabric resources are still being reserved for these VMs.  However, this also means that DIPs and VIPs are preserved for VMs in this state, so you don't have to worry about VMs and cloud services getting different IP addresses when they are started in the future. Stop VM via Windows PowerShell In the latest version of the Windows Azure PowerShell Module, a new -StayProvisioned parameter has been added to the Stop-AzureVM cmdlet. This new parameter provides the flexibility to choose the VM configuration end result when stopping VMs using PowerShell: When running the Stop-AzureVM cmdlet without the -StayProvisioned parameter specified, the VM will be safely stopped and deallocated; that is, the VM will be left in a "Stopped ( Deallocated )" status just like the end result when a VM Shutdown operation is performed via the Windows Azure Management Portal.  When running the Stop-AzureVM cmdlet with the -StayProvisioned parameter specified, the VM will be safely stopped but fabric resource reservations will be preserved; that is the VM will be left in a "Stopped" status just like the end result when performing a Guest OS shutdown operation. So, with PowerShell, you can choose how Windows Azure should handle VM configuration and fabric resource reservations when stopping VMs on a case-by-case basis. TIP: It's important to note that the -StayProvisioned parameter is only available in the latest version of the Windows Azure PowerShell Module.  So, if you've previously downloaded this module, be sure to download and install the latest version to get this new functionality.

  • Compare Your Internet Cost and Speed to Global Averages [Infographic]

    - by ETC
    Internet pricing and speed varies wildly across the world. The US, for instance, currently ranks 15th in speed but enjoys reasonably priced internet access. How reasonably priced? If you’re a US citizen you likely have an average internet access speed of 4.8 mbps and you pay a little over $3 per mbps. If you’re in Sweden, however, you likely have an 18 mbps connection and you pay a scant 63 cents per mpbs. The real envy of the internet speed Olympics by far is Japan with a mighty 61 mbps at a mere 27 cents per mbps.

  • Great Example of a Simple Cost-Benefit Analysis

    - by BuckWoody
    I saw a post the other day that you should definitely go check out. It’s a cost/benefit decision, and although the author gives it a quick treatment and doesn’t take all points in the decision into account, you should focus on the process he follows. It’s a quick and simple example of the kind of thought process we should have as data professionals when we pick a server, a process, or application and even platform software. The key is to include more than just the price of a piece of software or hardware. You need to think about the “other” costs in the decision, and then make the right one. Sometimes the cheapest option is the cheapest, and other times, well, it isn’t. I’ve seen this played out not only in the decision to go with a certain selection, but in the options or editions it comes in. You have to put all of the decision points in the analysis to come up with the right answer, and you have to be able to explain your logic to your team and your company. This is the way you become a data professional, not just a DBA. You can check out the post here – it deals with Azure, but the point is the process, not Azure itself: http://blogs.msdn.com/eugeniop/archive/2010/03/19/windows-azure-guidance-a-simplistic-economic-analysis-of-a-expense-migration.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Java and .NET cost of use [on hold]

    - by 1110
    I work with .NET technology stack for about 4 years. I am learning and enjoy working with ASP MVC framework and I never did anything serious in other languages. This is not the question like what is better (I read all similar questions). What interest me is the cost of switching. For example: If you are about to start a start-up company today and you are in my situation not too much money, some good idea that you think others will use and have a knowledge of .NET. In my head I have a few questions that I can't answer and I know that somebody with experience can: 1) Java & .NET hosting. Suppose shared hosting is not good enough anymore, your site has grown and you need more resources. How much Java services is cheaper compared to .NET? 2) I didn't follow hype about ORACLE will kill java long time. Does oracle show interest in investing in java. I mean is is safe to bet on java as a technology when starting start-up (basically did oracle show some will to destroy java platform)? 3) I am not sure what I am asking here. When you use Java you can use JEEE stack or Java with third party stack (spring, hibernate, maven etc.). I saw a lot of project that work with second option if web application is not enterprise level but social networking site for example which stack is best pick? Summary of this question is is it safe to jump in to Java learn it and build product based on it. It's not too hard for me to learn it. But how much can I get from it.

  • How do freelancers know how much their work is worth?

    - by Qmal
    I want to start a bit of freelancing in web development using ASP.NET MVC3 and PHP and I already have some people who are interested in hiring me, but I still can't figure out how much to charge for projects since I have never done it. For example how much would this site cost? Would it cost more if the author built it from scratch instead of using WordPress as the CMS? Or what about a simpler site like this? How much time spent is considered good/normal for building sites like these? And maybe some freelancers with experience can tell me what the usual requests are that they get from clients. What sites are the most in demand? I'm asking because I'm a student and I really can't work every day in a full-time job but I need the money so I guess a little freelancing would help me out.

  • Altruistic network connection bandwidth estimation

    - by datenwolf
    Assume two peers Alice and Bob connected over a IP network. Alice and Bob are exchanging packets of lossy compressed data which are generated and to be consumes in real time (think a VoIP or video chat application). The service is designed to cope with as little bandwidth available, but relies on low latencies. Alice and Bob would mark their connection with an apropriate QoS profile. Alice and Bob want use a variable bitrate compression and would like to consume all of the leftover bandwidth available for the connection between them, but would voluntarily reduce the consumed bitrate depending on the state of the network. However they'd like to retain a stable link, i.e. avoid interruptions in their decoded data stream caused by congestion and the delay until the bandwidth got adjusted. However it is perfectly possible for them to loose a few packets. TL;DR: Alice and Bob want to implement a VoIP protocol from scratch, and are curious about bandwidth and congestion control. What papers and resources do you suggest for Alice and Bob to read? Mainly in the area of bandwidth estimation and congestion control.

  • How many developers do I need to build a website like Freelancer.com in about 3-5 months? [closed]

    - by Sam
    I have been asked to make a list of people that I need to build something similar to freelancer.com. Not exactly same, has a few more features to it too but I can't really get my head around the whole freelancer.com site. I have built a social networking site from scratch which is 70% of Facebook and 20% Google+ in about 5 months with raw PHP, JS, CSS and Ajax. I dont think it will take me more than a month or something to build the whole freelancer.com from scratch. Please suggest anything that should I pay attention to. I am thinking about: 2 php developers 1 mysql engineer 1 network/server engineer 1 graphics artist 1 UI developer Time frame: 20 days Is this a good estimation?

  • How to minimize total cost of shortest path tree

    - by Michael
    I have a directed acyclic graph with positive edge-weights. It has a single source and a set of targets (vertices furthest from the source). I find the shortest paths from the source to each target. Some of these paths overlap. What I want is a shortest path tree which minimizes the total sum of weights over all edges. For example, consider two of the targets. Given all edge weights equal, if they share a single shortest path for most of their length, then that is preferable to two mostly non-overlapping shortest paths (fewer edges in the tree equals lower overall cost). Another example: two paths are non-overlapping for a small part of their length, with high cost for the non-overlapping paths, but low cost for the long shared path (low combined cost). On the other hand, two paths are non-overlapping for most of their length, with low costs for the non-overlapping paths, but high cost for the short shared path (also, low combined cost). There are many combinations. I want to find solutions with the lowest overall cost, given all the shortest paths from source to target. Does this ring any bells with anyone? Can anyone point me to relevant algorithms or analogous applications? Cheers!

  • What is better: set up underestimated or overestimated deadlines?

    - by sergdev
    Suppose you are a project manager. You can estimate an effort in days for specific task for specific developer. After performing estimation you obtain some min and max values. After this you delegate a task to developer. Actually you also set up deadline. Which estimation is better to use when set up deadline: min or max? As I see min estimation can result in stress for developer, max estimation can result in using all the time which is allocated to developer even if task can be complete faster (so called Student syndrome). Which other pros and cons of two approaches? Small clarification: I speak about setting up deadlines for subordinates when delegating the task, NOT for reporting to my boss.
