"After the reports on SSD reliability and after experiencing a costly 50% failure rate on over 200 remote-deployed OCZ Vertex SSDs, a degree of paranoia set in where I work. I was asked to carry out SSD analysis with some very specific criteria: budget below £100, size greater than 16Gbytes and Power-loss protection mandatory. This was almost an impossible task: after months of searching the shortlist was very short indeed. There was only one drive that survived the torturing: the Intel S3500. After more than 6,500 power-cycles over several days of heavy sustained random writes, not a single byte of data was lost. Crucial M4: failed. Toshiba THNSNH060GCS: failed. Innodisk 3MP SATA Slim: failed. OCZ: failed hard.
Only the end-of-lifed Intel 320 and its newer replacement, the S3500, survived unscathed. The conclusion: if you care about data even when power could be unreliable, only buy Intel SSDs."So make the power reliable...nerdguy0 (101358) <lwalkeraNO@SPAMieee.org>

"Research from Seagate suggests that hybrid hard drives in general use are virtually as good as solid state drives if they have just 8GB of solid state memory.
The research found that normal office computers, not running data-centric applications, access just 9.58GB of unique data per day. 8GB is enough to store most of that, and results in a drive which is far cheaper than an all-Flash device.
Seagate is confident enough to ease off on efforts to get data off hard drives quickly, and rely on cacheing instead. It will cease production of 7200 RPM laptop drives at the end of 2013, and just make models running at 5400 RPM."
Hmmm. Kinda reminds me of a story I once heard about IBM: that it took a huge amount of data gathering and persuasion to get IBM to adopt a new, or changed, policy/strategy/tactic. But that once adopted, having been through an exhausting process of approval, it was all but impossible to stop it, even when circumstances had significantly changed.
Or, in short, "this was approved and supported by (ex)President, and economics guru Larry Summers, so it must be right for all time".

Quick one, then I have to figure out how to get to Toulouse (missed connection, in Paris now ... but should be able to get there ... long day so far):Is the Information Technology Revolution Over?, by David M. Byrne, Stephen D. Oliner, and Daniel E. Sichel, FRB: Abstract: Given the slowdown in labor productivity growth in the mid-2000s, some have argued that the boost to labor productivity from IT may have run its course. This paper contributes three types of evidence to this debate. First, we show that since 2004, IT has continued to make a significant contribution to labor productivity growth in the United States, though it is no longer providing the boost it did during the productivity resurgence from 1995 to 2004. Second, we present evidence that semiconductor technology, a key ingredient of the IT revolution, has continued to advance at a rapid pace and that the BLS price index for microprocesssors may have substantially understated the rate of decline in prices in recent years. Finally, we develop projections of growth in trend labor productivity in the nonfarm business sector. The baseline projection of about 1¾ percent a year is better than recent history but is still below the long-run average of 2¼ percent. However, we see a reasonable prospect--particularly given the ongoing advance in semiconductors--that the pace of labor productivity growth could rise back up to or exceed the long-run average. While the evidence is far from conclusive, we judge that "No, the IT revolution is not over."
CommentsDarryl FKA Ron said...The pickup reflects ongoing advances in IT and an assumption that those gains and innovations in other sectors spur some improvement in multifactor productivity (MFP) growth outside of the IT sector relative to its tepid pace from 2004 to 2012.5 These developments feed through the economy to provide a modest boost to labor productivity growth.Darryl FKA Ron said in reply to Darryl FKA Ron...
[Using technology to replace people or make them more productive, generally considered the same thing, is one form of productivity increasing technology integration. Automating accounting functions from producing bills to meter reading or selling your goods on the WWW were examples of the revolution of picking low hanging fruit. Using technology to manage systems in ways that people could not realistically accomplish is another way of increasing productivity. From running power production and distribution, traffic lights, and just in time manufacturing integrated with ERP accounting systems from order entry through to shipping and general ledger were other ways of increasing productivity. The green fields of labor replacement have largely been sewn. The green fields of automated systems management are without end.

Computer technology with out software is just a paperweight. The technology revolution is stalled but not over. The problem as I see it and it seems to be everywhere is not nearly enough people paying for custom software development done in house.
Every company any bigger than a few employees needs someone on staff who manages software purchases, installation and the creation of custom software to make the bridge between a lot of chimerical software, but no one wants to pay for it.

Custom software that actually supports business critical processes tends to be quite expensive, with reason.
Another reason to avoid custom software is risk mitigation. A business that relies on software built by one "someone on staff" is running a real risk if/when that someone leaves.
Part of the unwillingness to pay is that people's expectations are influenced by consumer software price points, $0 to a few hundred dollars.A secondary inhibiter might be the growing mess in the software patent world.

For the US, much of the IT revolution was over after the major carriers killed the internet revolution in its tracks, and it ain't coming back anytime soon.
See 'Captive Audience' by Susan Crawford.Sunny Liu said in reply to kievite...
Situation is enterprise datacenters definitely corresponds to definition of stagnation. We see a lot of cost cutting.
Percentage of custom software is small and getting smaller as Observer already noted above. Programmers are disappearing from the enterprise IT departments.
At the same time a new dangerous trend is in place. Some "of-the-shelf" packages on which enterprise depends are problematic with some subsystems close to junk or even harmful (SAP/R3, some IBM products, etc). Moreover there is now a new type of enterprise software vendors who are specializing in selling completely useless or even harmful software on the pure strength of marketing (plus fashion). Vendor which try to capitalize on ignorance of a typical IT management layer.
Like Kolmogorov once said "You can't overestimate the level of ignorance of the audience". That was about different audience, but fully applicable here. So snake oil salesmen in IT are making good money, may be better than honest sailmen.
But the problems with "off-the-shelf" packages are increasing due to their often unwarranted complexity (which serves mainly as barrier of entry for competitors), or just complexity for the sake of complexity.
This and the fact that generally software is a the most complex artifact invented by mankind lead to the level of understanding of existing packages and operating systems that can be called dismal. Even people who "should know" often look like coming from the pages of "The Good Soldier Švejk" or "Catch 22". One Unix group manager in a large company that I used to know for example did not understand the fact that IBM Power servers and Intel servers are based on CPU with two different architectures. When at the meeting I realized that my jaw simply dropped.
People who saw the software evolution from its humble beginning and can understand internals and nature of compromises taken in existing hardware and software are now close to retirement and in the new generation such people are exceedingly rare.
That is true for operating systems such as Linux or Solaris, this is even more true for web-related software such as Apache, MediaWiki, Frontpage, etc. As a result a lot of things are "barely run" and a lot of system are bought just because people have no clue that already bought systems can perform the same functions.
This is also true about Office, especially Excel. One think that I noticed that the level of knowledge of Excel is really dismal across the enterprise. I would agree with "squidward" that for office (but only for office) "I would have to agree that now marginal increases in productivity due to IT aren't giving the same marginal increases in value to the end consumer. ". But that's for office only. Cars, homes, etc are still "terrra incognita".
But while internally everything looks rotten, externally situation looks different: there is unending assault of automation on existing jobs. So JT is on something when he asks the question "The more interesting comparison, is in industry that use a lot of IT, has their productivity improved?" Yes and to the extend that many workforce cuts are permanent and moreover cuts might continue.
As for statement "For the US, much of the IT revolution is over" I doubt it. Computer will continue to eat jobs. The "cutting edge" simply moved elsewhere and one hot area are various robotic systems. Here is one example:
"IBM is using robots based on iRobot Create, a customizable version of the Roomba vacuum cleaner, to measure temperature and humidity in data centers. The robot looks for cold zones (where cold air may be going to waste instead of being directed to the servers) and hotspots (where the air circulation may be breaking down. IBM is putting the robots to commercial use at partners — while EMC is at an early stage on a strikingly similar project."
Both home and datacenter are huge application areas. Even in consumer electronics what we have is still very primitive in comparison with what is possible on the current hardware. That is true for smartphones, tablets and other mass gargets. And it is even more true for home. For example for older people a cutting edge computer technology can probably provide the level of service comparable with the level of service of nursing home. Automated cook who accepts a simple menu and deliver dishes is already feasible automation. Currently the cost will be high but gradually it will drop and quality of service improves. One interesting area is saving energy. How many people here have home network which integrates thermostat, outdoor and indoor lights, and security system. And probably nobody here has computer automated shades on windows.
Autonomous datacenters with robot service are in my opinion an interesting development which in many cases can serve as "distributed cloud".
I agree. That was a wonderfully informative post, and thank you for that. I also don't think it's even close to over not just because of robotics but also because of machine learning. The implications for data mining and big data are enormous, and the research being done in those fields are still yet to be fully utilized.
Right now, machine learning and big data are advancing research in biology, but what about the optimizations possible in pharmaceuticals or manufacturing?
not sure if this qualifies as IT. Not even sure if that is a meaningful distinction, but as a distributor I can't help thinking that 3D printers will have a profound impact on both manufacturing and distribution.
The issue now becomes whether the technology will transform manufacturing more broadly. At the moment, 3D printing is a small part of the economy. The printers are typically slow, and the material they use is expensive and inconsistent. As the industry advances, however, printing on demand could reduce assembly lines, shorten supply chains, and largely erase the need for warehouses for many companies. Cutting back on shipping and eliminating the waste and pollution of traditional manufacturing could be an environmental boon.
The software revolution is over, just the same way the written word revolution ended in 1900.
Does increased labor productivity increase living standards? What if the products are lower quality and either must be disposed of sooner than if they were of higher quality or incur greater lifecycle service costs than if they were of higher quality? If increased productivity degrades the natural environment (air, water, soil, food) are living standards increased? If productivity numbers increase because more people are unemployed or under employed or suffer stagnant or lower wages from globalization has the standard of living increased?
Looking at aggregate data glosses losers and winners. For the last three decades the winners are relatively fewer in number but grabbing a greater share of GDP, while the loser are vastly greater in number and have fewer opportunities to be winners other than through random luck (marriage, inheritance, connections).
Is IT innovation necessarily good or more productive? The increase in semiconductor performance (pick your metric) at a given price, or even lower price, will not increase productivity if you already have all the IT performance you can use. In some cases, it might reduce productivity. E.g., having larger hard drives means more data will be collected (data collects to fill the space available: Shillock’s Second Law of Storage). Unless one has efficient methods to keep track of it all then searching for it will reduce productivity. Also, access and seek times have not improved linearly with capacity. Another hit to productivity from IT. This is why the Fed’s incorporation of a “hedonic index” for microprocessors into its price index muddies the water (c.f. p. 8)
What if some IT innovation gives a company a competitive edge such as happened in finance? Others are compelled to adopt it ASAP but that does not necessarily make the financial industry more productive. Indeed, it facilitated fraud on a massive scale that caused the Great Recession while leaving insiders vastly wealthier for it. It could be argued that IT innovations have facilitated the increasing and increasingly server financial crises over the past three decades, if only because they create the delusion among users that they know more than they do thereby feeding their hubris.
The Dictatorship of Data http://www.technologyreview.com/news/514591/the-dictatorship-of-data/
Most of the gains to productivity from IT are in two areas. First, is that large financial and reservation systems. These run on IBM mainframes. The second is the application of smaller computers to manufacturing to run tools. The vast amount of PC level IT probably reduces productivity because most people do not know how to use it. Word processors allow more people to take more time making their emails and interoffice memos grammatically better and with fewer spelling errors. Most people have little clue how to use spreadsheets, even Rinehart and Rogoff were challenged. PowerPoint and similar PC apps are great for enabling the incompetent and ignorant to appear otherwise, which accounts for their popularity. They are the lingua franca of IBM. So far Facebook, Twitter, LinkedIn, etc. are a great waste of time for the neurotically self-conscious and self-important.
Economics is a literary genre in which contestants focus only on the numbers and usually those they like then use their imaginations to spin stories about the numbers. Audiences then vote on which story they find most pleasing.

Yesterday’s Wall Street Journal had an article titled “Foosball over Finance” about how people in finance have been switching to technology startups, for all the predictable reasons: The long hours in finance. “Technology is collaborative. In finance, it’s the opposite.” “The prospect of ‘building something new.’” Jeans. Foosball tables. Or, in the most un-self-conscious, over-engineered, revealing turn of phrase: “The opportunity of my generation did not seem to be in finance.”
We have seen this before. Remember Startup.com? That film documented the travails of a banker who left Goldman to start an online company that would revolutionize the delivery of local government services. It failed, but not before burning through tens of millions of dollars of funding. There was a time, right around 1999, when every second-year associate wanted to bail out of Wall Street and work for an Internet company.
The things that differentiate technology from banking are always the same: the hours (they’re not quite as bad), the work environment, “building something new,” the dress code, and so on. They haven’t changed in the last few years. The only thing that changes are the relative prospects of working in the two industries—or, more importantly, perceptions of those relative prospects.
Wall Street has always attracted a particular kind of person: ambitious but unfocused, interested in success more than any achievements in particular, convinced (not entirely without reason) that they can do anything, and motivated by money largely as a signifier of personal distinction. If those people want to work for technology startups, that means two things.
- First, they think they can amass more of the tokens of success in technology than in finance.
- Second—since these are the some of the most conservative, trend-following people that exist—it means they’re buying at the top.

Welcome to the world of essential services. When your job is to keep things working, you don't get to pick your hours cause shit happens.

The current level of EPS was reached by a combination of two things: (1) offshoring jobs and (2) killing the pension fund (IBM stopped contributing to its pension fund in 2007 – all subsequent benefit dollars have gone into 401k plans). Lots of other shenanigans too of course, documented well in the book “Retirement Heist: How Companies Plunder and Profit from the Nest Eggs of American Workers” by Ellen Schultz.
Since (2) has already been done, to redouble EPS again to $20 per share will require an even greater rate of US job elimination than we have seen in the past.
They have also done other little things. Yes, retirees can purchase health insurance through IBM, but retirees are placed into their own insurance pool rather than being co-insured with all employees. Result: (much) higher rates. Result of higher rates: retirees cannot afford health insurance ==> retirees die sooner ==> lower pension costs for IBM ==> higher EPS!

I’m amazed that IBM offers former employees health insurance at all. The trend is not to insure anyone who isn’t currently employed, and then offer only scant overpriced difficult to collect insurance. 40,000 Americans die for lack of health care every year in a health care system ranked 37 in the world after all other developed countries. So ex-IBM employees seem to have it better than most.
- sadIBMer says:
If the US is ranked 37, why do people from almost every other country come to the US for health care? Doesn’t make sense to me.
- gavin says:
There are certain clinics that cater to the megarich that provide “the best” care. Corrupt elites from all over the world come to get treatment there for certain conditions. Other such clinics exist for other conditions in other parts of the world. Average people in your country couldn’t afford them even with insurance. I think most Americans understand that they are going to be getting the 37th in the world treatment…or worse. It’s well recognized that most rural areas in the U.S. have treatment standards lower than many third world countries.
- Ronc says:
The clinics exist because they are allowed to exist and thrive. That fact pushes medical progress forward which eventually benefits others just like any other technology.
- Seenitall says:
That ranking of 37th is based on the WHO formula of ‘consistency over quality’. Since the US has the greatest healthcare in the world, when you can afford it, yet offers only minimal coverage for it’s poor, the disparity gives the US a poor ranking. IOW, a country can have very poor healthcare, but if it’s consistent for all of the population, the country will receive a high rank.
- jim says:
The WHO ranking takes into account such factors as %insured, infant mortality,life expectancy, etc. The US does not rank in the top 5 in any of these categories, yet has a cos health care much higher than other developed countries. The health care most middle class Americans receive is no better, but more expensive than their counterparts in Europe and Japan. The care provided to the poor is well below the standard in developed countries.
Despite the fact that technology plays an increasingly important role in the economy, IT wages remain persistently flat. This may be tech's inconvenient truth.
The still sluggish U.S. economy gets most of the blame for this wage stagnation, but factors such as outsourcing and automation also contribute to the problem, say analysts.
"IT salaries have not really kept pace with inflation," said Victor Janulaitis, the CEO of Janco Associates, which reports on IT wage compensation.
In 2000, the average hourly wage was $37.27 in computer and math occupations for workers with at least a bachelor's degree. In 2011, it was $39.24, adjusted for inflation, according to a new report by the Economic Policy Institute (EPI).

What happened to the old "sysadmin" of just a few years ago? We've split what used to be the sysadmin into application teams, server teams, storage teams, and network teams. There were often at least a few people, the holders of knowledge, who knew how everything worked, and I mean everything. Every application, every piece of network gear, and how every server was configured -- these people could save a business in times of disaster.
Now look at what we've done. Knowledge is so decentralized we must invent new roles to act as liaisons between all the IT groups. Architects now hold much of the high-level "how it works" knowledge, but without knowing how any one piece actually does work. In organizations with more than a few hundred IT staff and developers, it becomes nearly impossible for one person to do and know everything. This movement toward specializing in individual areas seems almost natural. That, however, does not provide a free ticket for people to turn a blind eye.
You know the story: Company installs new application, nobody understands it yet, so an expert is hired. Often, the person with a certification in using the new application only really knows how to run that application. Perhaps they aren't interested in learning anything else, because their skill is in high demand right now. And besides, everything else in the infrastructure is run by people who specialize in those elements. Everything is taken care of.
Except, how do these teams communicate when changes need to take place? Are the storage administrators teaching the Windows administrators about storage multipathing; or worse logging in and setting it up because it's faster for the storage gurus to do it themselves? A fundamental level of knowledge is often lacking, which makes it very difficult for teams to brainstorm about new ways evolve IT services. The business environment has made it OK for IT staffers to specialize and only learn one thing.
If you hire someone certified in the application, operating system, or network vendor you use, that is precisely what you get. Certifications may be a nice filter to quickly identify who has direct knowledge in the area you're hiring for, but often they indicate specialization or compensation for lack of experience.
Does your IT department function as a unit? Even 20-person IT shops have turf wars, so the answer is very likely, "no." As teams are split into more and more distinct operating units, grouping occurs. One IT budget gets split between all these groups. Often each group will have a manager who pitches his needs to upper management in hopes they will realize how important the team is.
The "us vs. them" mentality manifests itself at all levels, and it's reinforced by management having to define each team's worth in the form of a budget. One strategy is to illustrate a doomsday scenario. If you paint a bleak enough picture, you may get more funding. Only if you are careful enough to illustrate the failings are due to lack of capital resources, not management or people. A manager of another group may explain that they are not receiving the correct level of service, so they need to duplicate the efforts of another group and just implement something themselves. On and on, the arguments continue.
Most often, I've seen competition between server groups result in horribly inefficient uses of hardware. For example, what happens in your organization when one team needs more server hardware? Assume that another team has five unused servers sitting in a blade chassis. Does the answer change? No, it does not. Even in test environments, sharing doesn't often happen between IT groups.
With virtualization, some aspects of resource competition get better and some remain the same. When first implemented, most groups will be running their own type of virtualization for their platform. The next step, I've most often seen, is for test servers to get virtualized. If a new group is formed to manage the virtualization infrastructure, virtual machines can be allocated to various application and server teams from a central pool and everyone is now sharing. Or, they begin sharing and then demand their own physical hardware to be isolated from others' resource hungry utilization. This is nonetheless a step in the right direction. Auto migration and guaranteed resource policies can go a long way toward making shared infrastructure, even between competing groups, a viable option.
The most damaging side effect of splitting into too many distinct IT groups is the reinforcement of an "us versus them" mentality. Aside from the notion that specialization creates a lack of knowledge, blamestorming is what this article is really about. When a project is delayed, it is all too easy to blame another group. The SAN people didn't allocate storage on time, so another team was delayed. That is the timeline of the project, so all work halted until that hiccup was restored. Having someone else to blame when things get delayed makes it all too easy to simply stop working for a while.
More related to the initial points at the beginning of this article, perhaps, is the blamestorm that happens after a system outage.
Say an ERP system becomes unresponsive a few times throughout the day. The application team says it's just slowing down, and they don't know why. The network team says everything is fine. The server team says the application is "blocking on IO," which means it's a SAN issue. The SAN team say there is nothing wrong, and other applications on the same devices are fine. You've ran through nearly every team, but without an answer still. The SAN people don't have access to the application servers to help diagnose the problem. The server team doesn't even know how the application runs.
See the problem? Specialized teams are distinct and by nature adversarial. Specialized staffers often relegate themselves into a niche knowing that as long as they continue working at large enough companies, "someone else" will take care of all the other pieces.
I unfortunately don't have an answer to this problem. Maybe rotating employees between departments will help. They gain knowledge and also get to know other people, which should lessen the propensity to view them as outsiders
