  • Building a distributed system on Amazon Web Services

    - by Songo
    Would simply using AWS to build an application make this application a distributed system? For example if someone uses RDS for the database server, EC2 for the application itself and S3 for hosting user uploaded media, does that make it a distributed system? If not, then what should it be called and what is this application lacking for it to be distributed? Update Here is my take on the application to clarify my approach to building the system: The application I'm building is a social game for Facebook. I developed the application locally on a LAMP stack using Symfony2. For production I used an a single EC2 Micro instance for hosting the app itself, RDS for hosting my database, S3 for the user uploaded files and CloudFront for hosting static content. I know this may sound like a naive approach, so don't be shy to express your ideas.

  • Managing Operational Risk of Financial Services Processes – part 1/ 2

    - by Sanjeevio
    Financial institutions view compliance as a regulatory burden that incurs a high initial capital outlay and recurring costs. By its very nature regulation takes a prescriptive, common-for-all, approach to managing financial and non-financial risk. Needless to say, no longer does mere compliance with regulation will lead to sustainable differentiation.  Genuine competitive advantage will stem from being able to cope with innovation demands of the present economic environment while meeting compliance goals with regulatory mandates in a faster and cost-efficient manner. Let’s first take a look at the key factors that are limiting the pursuit of the above goal. Regulatory requirements are growing, driven in-part by revisions to existing mandates in line with cross-border, pan-geographic, nature of financial value chains today and more so by frequent systemic failures that have destabilized the financial markets and the global economy over the last decade.  In addition to the increase in regulation, financial institutions are faced with pressures of regulatory overlap and regulatory conflict. Regulatory overlap arises primarily from two things: firstly, due to the blurring of boundaries between lines-of-businesses with complex organizational structures and secondly, due to varying requirements of jurisdictional directives across geographic boundaries e.g. a securities firm with operations in US and EU would be subject different requirements of “Know-Your-Customer” (KYC) as per the PATRIOT ACT in US and MiFiD in EU. Another consequence and concomitance of regulatory change is regulatory conflict, which again, arises primarily from two things: firstly, due to diametrically opposite priorities of line-of-business and secondly, due to tension that regulatory requirements create between shareholders interests of tighter due-diligence and customer concerns of privacy. For instance, Customer Due Diligence (CDD) as per KYC requires eliciting detailed information from customers to prevent illegal activities such as money-laundering, terrorist financing or identity theft. While new customers are still more likely to comply with such stringent background checks at time of account opening, existing customers baulk at such practices as a breach of trust and privacy. As mentioned earlier regulatory compliance addresses both financial and non-financial risks. Operational risk is a non-financial risk that stems from business execution and spans people, processes, systems and information. Operational risk arising from financial processes in particular transcends other sources of such risk. Let’s look at the factors underpinning the operational risk of financial processes. The rapid pace of innovation and geographic expansion of financial institutions has resulted in proliferation and ad-hoc evolution of back-office, mid-office and front-office processes. This has had two serious implications on increasing the operational risk of financial processes: ·         Inconsistency of processes across lines-of-business, customer channels and product/service offerings. This makes it harder for the risk function to enforce a standardized risk methodology and in turn breaches harder to detect. ·         The proliferation of processes coupled with increasingly frequent change-cycles has resulted in accidental breaches and increased vulnerability to regulatory inadequacies. In summary, regulatory growth (including overlap and conflict) coupled with process proliferation and inconsistency is driving process compliance complexity In my next post I will address the implications of this process complexity on financial institutions and outline the role of BPM in lowering specific aspects of operational risk of financial processes.

  • Empty $_POST data

    - by Antimony
    I am trying to post a post to my MyBB server from a Python script, but try as I might, I can't get it to work. The request shows up in the forensic log and the headers are in the $_SERVER variable, but $_POST is always an empty array. The error log shows nothing, even at the debug level. I've already tried searching, but I haven't found anything that's helped. I already checked the post_max_size thing, which is 8M. Another factor is that it's just my own requests which aren't going through. Browser generated requests seem to do just fine. I've looked and looked, but I can't find anything I'm doing differently that should matter. Anyway, here is an example request. POST /newreply.php?tid=1&processed=1 HTTP/1.1 Host: <redacted> Accept-Encoding: identity Content-Length: 1153 Content-Type: multipart/form-data; boundary=-->0xa216654L Cookie: sid=<redacted>; mybb[lastvisit]=1354995469; mybb[lastactive]=1354995500; mybb[threadread]=a%3A1%3A%7Bi%3A1%3Bi%3A1354995469%3B%7D; mybb[forumread]=a%3A1%3A%7Bi%3A2%3Bi%3A1354995469%3B%7D; loginattempts=1; mybbuser=2_ZlVVfaYS9FstZGQzr4KiNRUm3Z4xAgJkTPPq2ouFcuaragOTVQ Accept: text/html User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:14.0) Gecko/20100101 Firefox/14.0.1 -->0xa216654L Content-Disposition: form-data; name="my_post_key" 257b2bbef4334000d9088169154900a3 -->0xa216654L Content-Disposition: form-data; name="quoted_ids" -->0xa216654L Content-Disposition: form-data; name="tid" 1 -->0xa216654L Content-Disposition: form-data; name="message" foo!2 -->0xa216654L Content-Disposition: form-data; name="attachmentact" -->0xa216654L Content-Disposition: form-data; name="attachmentaid" -->0xa216654L Content-Disposition: form-data; name="icon" -1 -->0xa216654L Content-Disposition: form-data; name="posthash" e93a2c78ce3f6807a86fd475ef4178cf -->0xa216654L Content-Disposition: form-data; name="postoptions[subscriptionmethod]" -->0xa216654L Content-Disposition: form-data; name="replyto" -->0xa216654L Content-Disposition: form-data; name="message_new" foo!2 -->0xa216654L Content-Disposition: form-data; name="submit" Post Reply -->0xa216654L Content-Disposition: form-data; name="attachment"; filename="" Content-Type: application/octet-stream -->0xa216654L Content-Disposition: form-data; name="action" do_newreply -->0xa216654L Content-Disposition: form-data; name="subject" Lol -->0xa216654L

  • Can't start webcam for google video services

    - by wisemonkey
    I've got Ubuntu 11.10 64 bit and have installed the google video chat plugin. However webcam doesn't seem to work (black screen -- no video at all). For cheese it works but shows really bad (black and white kinda) image. Following some link I installed guvcview if I start it then image looks neat. Any suggestions on how can it be fixed? If it helps I've tried the solution: $ sudo mv /opt/google/talkplugin/GoogleTalkPlugin /opt/google/talkplugin/GoogleTalkPlugin.old $ sudo gedit /opt/google/talkplugin/GoogleTalkPlugin and putting following lines in: #!/bin/sh LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so /opt/google/talkplugin/GoogleTalkPlugin.old OR #!/bin/sh LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so /opt/google/talkplugin/GoogleTalkPlugin.old Cause I've both files. Finally $sudo chmod +x /opt/google/talkplugin/GoogleTalkPlugin.old I closed and reopened chrome then started gmail tried video call -- black screen :-/ Ok so today finally google+ provided me with trouble shoot link and advised me: The plug-in won't install If you're having trouble installing the plug-in, or are receiving a message asking you to reinstall it, you should check to make sure your configuration is right. To do so simply: Check to make sure the Google Talk Plugin Video Accelerator and Google Talk NPAPI Plugin are enabled. If you're using Chrome you can type about:plugins in your browser to display your plug-ins. Make sure you're not using Internet Explorer 64-bit (this is a browser version that is 64 bit as opposed to 32 bit). Ensure that you don't have any "click to run" extensions enabled. If you're still experiencing this issue after checking your configuration you can follow these steps: Refresh the browser page. Close any running Google Talk plug-in processes. Close all open and running browser processes. Restart your computer. Uninstall and then reinstall the plug-in. Try a different browser such as Google Chrome or Mozilla Firefox. I looked in about:plugins for chrome and firefox: I don't have Google Talk NPAPI Plugin, does that matter? and I thought its installed with google talk plugin or no?

  • How Big Data and Social Won the Election

    - by Mike Stiles
    The story of big data’s influence on the outcome of the US Presidential election is worth a good look, because a) it’s a harbinger of things to come, and b) it’s an example of similar successes available to any enterprise seriously resourcing integrated big data, modeling, and data-driven execution on all assets, including social. Obama campaign manager Jim Messina fielded a data and analytics brain trust 5 times larger than 2008. At that time, there were numerous databases from various sources, few of them talking to each other. This time, the mission was to be metrics-centered and measure everything measurable, and in context with all the other data. Big data showed them exactly what they needed to know and told them what to do about it. It showed them women 40-49 on the west coast would donate big money if they got to eat with George Clooney. Women on the east coast would pony up to hang out with Sarah Jessica Parker. Extensive daily modeling showed them what kinds of email appeals, from who, and to whom, would prove most successful in raising cash, recruiting volunteers, and getting out the vote. Swing state voters were profiled and approached with more customized targeting that at any time in history. Ads were purchased on specific shows watched by the targets, increasing efficiency 14% over traditional media buys. For all the criticism of the candidate’s focus on appearing on comedy and entertainment shows, and local radio morning shows, that’s where the data sent them to reach the voters most likely to turn out for them. And then there was social. Again, more than in any other election, Facebook was used for virtual, highly efficient door-to-door canvasing. Facebook fans got pictures of friends in swing states and were asked to encourage them to act. Using that approach, 1 in 5 peer-to-peer appeals led to the desired action. Assumptions, gut, intuition, campaign experience, all took a backseat to strategy shifts solidly backed up by data. Zeroing in on demographics likely to back the President and tracking their mood daily literally changed the voter landscape. The Romney team watched Obama voters appear seemingly out of thin air. One Obama campaign aide said, “We ran the election 66,000 times every night.” Which brings us to your organization. If you’re starting to feel like the battle-cry of “but this is the way we’ve always done it” is starting to put you in an extremely vulnerable position, you’re right. Social has become a key communication tool of the 21st century. Failing to use it, or failing to invest in a deep understanding of who your customers and prospects are so the content you post there will achieve desired actions and results, will leave you waking up one morning wondering, “What happened?”@mikestilesPhoto stock.xchng

  • Configure firewall (Shorewall/UFW) to allow traffic for services on an Ubuntu Server

    - by Niklas
    I have an Ubuntu Server 11.04 x64 which I want to secure. The server will be open to Internet and I want to be able to SSH/SFTP into the machine and the SSH-server runs on a custom set port. I also want a web server accessible from the Internet. These tasks seems not to hard to perform but I also want SAMBA-shares to be accessible from within the local network and this seems to be a bit trickier. If possible I also want to be able to "stealth" the ports necessary to protect the server further but also allow the SAMBA-shares to be automatically found within the local network. I've never configured firewalls before except for a router and I always bump into a bunch of problem when doing it all by myself so I was hoping for some tips or preferably a guide on how to this. Thank you! Update: On second thought I'd could just as likely go with UFW if the same settings are achievable ("stealth" ports).
