A programming lesson I keep relearning.
The design of the central data structure of an app determines the quality of the app, in every way.
Any extra thought that goes into this, will pay off in:
1. Maintainability of the code.
2. Size of the code (you'll write less code with a well thought-out central data structure).
3. Simplicity of the user interface (the structure inevitably shows through in the UI).
4. Ability to respond to feature requests.
5. Adapt to new hardware, OS changes, other apps.
6. More "it just works" experiences.
This is why it's sometimes the right thing to start over from scratch. Programmers often want to start over because they look at the code and it looks complicated, and they think they can make it simpler if they start over. They're right, of course, it will be simpler when they start over, because it won't do nearly as much as the mature product does. Once they finish building out the feature set, it may well be just as complicated.
It's a judgement call. I remember looking at the source of Unix kernel for the first time as a grad student in Wisconsin, and being amazed at the simplicity and obviousness of the code. I couldn't believe something so simple actually worked. Your code at its kernel level must have this simplicity. But at the edges, where you're accomdating the minds of users, inevitably it gets a little messy. The key thing to look for is how hard is it to add a completely new feature. It should be easy to do that. If it's not, it's likely because of a poorly organized (and therefore not well-understood) central data structure.
I've rewritten apps many times, over many years, because when I wrote the first or second versions, I didn't understand the problem well enough, and the code had turned into a morass of patches and workarounds.
Right now I'm recoding the internals of a special-purpose aggregator. I've written many of these, over the years, always quickly, trying to get something running fast, and then lived with data structures that resulted. This time I'm going slowly and carefully, with an installed base of one (me) and ripping up the pavement whenever I find even a slightly better way of doing something. I have other users who are waiting, but that's life.

Critical vulnerabilities in common PC software, including both applications and operating systems, continue to grow in number and stand as the leading cause for concern in the IT security landscape today, according to training experts at the SANS Institute.Holes in so-called client-side applications, including Web browsers, e-mail clients, productivity suites, and media players, have become particularly worrisome over the last year, according to SANS, which highlighted the issue as part of its annual report on the top 20 Internet security risks for 2007.As hackers have shifted their attention further away from operating system flaws and drilled down to applications-layer vulnerabilities they have found a seemingly endless wealth of possibilities for infecting PCs with everything from spyware to botnet programs, SANS researchers contend.Unless something can be done to improve software developers' coding habits or better test popular applications for such issues before they land on end-users' machines, attackers will be able to continue their successful assaults against enterprise networks and devices for the foreseeable future, said Rohit Dhamankar, project manager for the Top 20 report at SANS and a senior manager of security research for TippingPoint.?"There's just been such a dramatic rise in the numbers of vulnerabilities found in applications like Internet Explorer and Microsoft Office and a number of media players that attackers are having their way," said Dhamankar. "Enterprises are bolstering security, but desktop users still pose a massive risk if they can download anything they want from the Web; the attacks are also growing in sophistication to the extent that many can defeat antivirus and other security systems primarily by obfuscating their code."Some of the most powerful tools that hackers have adopted in hunting for potential targets are the same industrial-strength applications fuzzing tools that software vendors themselves are using to search for holes in their products, said the expert.Enterprises could do themselves a favor by enforcing stricter policies that dictate the types of applications that end-users are allowed to put on their work machines and using technical means to ensure that those rules are being followed, Dhamankar said.Other SANS researchers noted that while companies may not want to tell end-users that they cannot utilize media players, messaging clients, and other applications that have moved into the business world from the consumer sector, they could help themselves out by limiting the variety of client-side applications that people may choose from."IT departments can't focus on all the applications of the world, but they can choose several and keep their eye on those while allowing end-users some freedom," said Amol Sarwate, research manager at Qualys who studies vulnerability patterns for SANS. "What companies need to do is enforce standards for applications usage and utilize technical means to block unwanted software, devices, and even wireless access points."While many businesses have already realized that they need to shift more of their efforts toward defending client-side vulnerabilities, most have failed to embrace a proactive approach versus simply keeping track of publicly-reported flaws and patching those issues said Sarwate.Enterprises need to think about future security issues
It will be particularly important for firms to examine the additional security issues that will be introduced in the coming years with broader adoption of technologies including VoIP (Voice over IP), according to the expert."The key is for people to start thinking ahead of these client-side vulnerabilities to understand what the next big thing may be. Things like VoIP need to be examined for their security implications," said Sarwate. "Many companies are already adopting these tools because of all the advantages they offer, but there will be many attacks carried out against these systems as well."Among the advice that SANS is offering organizations hoping to improve their client-side security coverage is to mandate secure configurations at installation time for all applications, to constantly verify patching and upgrading of both applications and system software, to scan for new vulnerabilities frequently, and to keep their security systems up to date.Other leading areas of concern highlighted by SANS in its report included critical vulnerabilities in Web applications that allow for cross-site scripting attacks or for computers to be otherwise compromised simply by pointing their browsers at poisoned URLs."Gullible, busy, accommodating computer users," including executives, IT staff, and others with privileged access also remain a major weak point for enterprise security, according to SANS, as these seemingly more seasoned users of computers and software are still falling for increasingly targeted spear-phishing campaigns in large numbers.One of the best ways to educate users about the problem is for organizations to create fake spear-phishing threats and send them out to internal users to determine which individuals might be most likely to fall for the schemes and follow up with additional training, the group said.Critical vulnerabilities in the software and systems that provide the operating environment and primary services to computer users, or server-side software, remain another area of leading concern, according to SANS.Problems in Microsoft Windows services, Unix and Mac OS services, back-up and AV programs, management servers, database software, and VoIP technologies in particular are proving troublesome, according to the report.Many of those issues can be addressed by following the same advice offered for solving client-side vulnerabilities, SANS said in the research. |

Enterprise content management and social networking form a natural nexus that is already taking tangible form, a software executive said during a panel discussion Wednesday at the Gilbane Group's annual conference in Boston."People have real requirements to secure information, but also have a demand to interact with people," said John Newton, CTO of Alfresco, an open-source content management software maker. "We are starting to blur the lines between what's inside the enterprise and what's outside the enterprise."Panelist David Mendels, senior vice president of Adobe's enterprise and developer business unit, echoed the idea. "The biggest single shift we're seeing is from the infrastructure of content management to humans -- to how humans engage with it," he said. "The real question is, what experiences are you going to build for your end-users, and how are you going to securely connect that back to your back-end systems?"David Boloker, CTO of the company's emerging Internet technology group, touched upon security concerns as well. "When you end up in the Facebook world or the Web world, you have to ask yourself, is that information correct? Do you have to annotate it, do you have to clean that information?""There are people out there who will try to take your information or plant a worm," he added.Mendels predicted that enterprise rights management software for securing content will see wider use. "We've talked about this for a while, but I think we're really on the cusp of it starting to accelerate," he said.Beyond addressing bottom-line concerns, such as security, enterprises will soon be compelled to apply social-networking principles in a wider range of areas, said Andy MacMillan, vice president of product management in Oracle's enterprise content management division. "The Web is going to lead the way, but pretty soon, you're going to be talking about the call center, the checkout kiosk at the airport -- how do I personalize those things?"Panelists took questions following the main discussion. One audience member asked them to render an opinion on content management's adoption rate around the world.Newton said lower-cost options have diversified the roles of content management software: "We see content management being pulled into types of applications it normally wouldn't have been before.... It's changing -- it's much more democratized. It's not so much about compliance."Mendels said hosted content management services, such as Adobe's Share and Buzzword offerings, will see faster growth outside the U.S., particularly among SMBs.Panelists at one point peered into their respective crystal balls. Mendels said Adobe's goal moving forward is "creating applications and experiences that keep people in context."Ideally, he said, the current practice of jumping among e-mail programs, instant messaging services, and the phone would be no more. "We see a world where you should have all those experiences tied to one document," he said.Mendels gave the example of a person sending an e-mail that prompts the recipient to return the query by phone. "Instead of picking up the phone and calling you, the document can call you," he said.Boloker pointed to mashups, saying they represent a new "application paradigm we're all walking into." IBM is working on a drag-and-drop mashup development environment called QEDWiki, which Boloker demonstrated for IDG News Service following the panel discussion.MacMillan said enterprises must now focus on not just cataloging their structured and unstructured data, but also applying analytics against it. "I think the next big step for content management from the infrastructure layer is to turn BI loose on it," he said.But Newton's take centered more on philosophy than a given technology. The Web 2.0-social networking boom has unleashed a "wave of creativity" that stands in contrast to "introverted, left-brain thinking" types, in Newton's view. "What our industry needs to do is get out of our left-brain, introverted mindset," he said. |

Memory maker Micron Technology on Wednesday introduced a line of solid-state drives (SSDs) and said it would plug the technology into portable storage devices by mid- to end 2008.Micron's new RealSSD hard drive, announced at an event in San Francisco, will come in sizes of 1.8 inches and 2.5 inches with storage capacities of 32GB and 64GB. Micron also announced embedded SSD modules for blade servers with storage capacities of 1GB to 8GB.Purported by many to be the future replacement of hard drives, the growth of SSDs has been stymied by high pricing, longevity, and storage issues. However, the power-efficient and ruggedness of SSDs may attract users, said Dean Klein, vice president of memory system development at Micron.RealSSD is 50 percent lighter than standard hard drives, and at under 2 watts of power consumption, the drives will be ideal for laptops, Klein said. The drives also support the SATA II interface, a standard typically used to connect hard drives to computer systems.With no moving parts, RealSSD drives also have a rugged design and store data reliably. They handle vibrations and resist shock better than rotating media, Klein said.Despite multiple advantages, SSDs may not replace hard drives as storage devices in the near future, he said. SSD technology is under development, and some markets are sensitive to price-per-gigabyte of SSDs, Klein said.SSDs currently cost between $7 and $10 per gigabyte, making them much more expensive than hard drives, which cost $0.20 to $0.30 per gigabyte, according to data from research firm iSuppli.Initial consumers for RealSSD could be OEMs or enterprises, which look for reliability and high data throughput, and laptop consumers, which require portability and power efficiency, Klein said.RealSSD drives could reach consumers in the form of portable storage devices or ExpressCards by mid- to end 2008, depending on consumer demand, Mark Adams, Micron's vice president of digital media said in an interview. An ExpressCard fits in a laptop's PCMCIA slot.Sending SSDs to consumers immediately is questionable as the emerging technology hasn't proven itself yet, Adams said. There is a risk in being first-to-market if the product doesn't sell, which will build up unnecessary inventory of SSDs. Instead, Micron will try to get feedback from OEMs that include SSDs in their products and develop devices accordingly, Adams said.Micron sells portable consumer storage devices through Lexar Media, which it acquired last year.There are already a few vendors that include SSDs in their hardware. Aurora, a gaming systems manufacturer, includes them in its Area-51 ALX and Aurora ALX desktop PCs, and Toshiba includes SSDs in its laptops. |
