Comment Re:agent strings... (Score 1) 381

With both Firefox and SeaMonkey, it is very easy to spoof agent strings, to lie to Web servers by indicating I am using some browser that I have not installed. Actually, the default configuration of SeaMonkey has the user string
          Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0 SeaMonkey/2.22.1
which says it is both Firefox and SeaMonkey.

Comment Other: SeaMonkey (Score 4, Interesting) 381

My preferred browser is SeaMonkey. It has the same "guts" as Firefox but a different user interface that I consider far superior to Firefox. By "guts", I mean the same HTML rendering engine, the same Internet interface, the same SSL processes, and often the same third-party extensions. However, SeaMonkey allows experienced users to tailor the browser in ways that Firefox does not.

It appears that Mozilla has been slowly "dumbing down" Firefox. In the process, the developers have also gone overboard in attempting to make Firefox super-safe for users, which is the main cause of the loss of tailoring. This safety is not restricted to browsing the Web safely but also in configuring the user's own computer. This sometimes means a loss of functionality, overcome by a proliferation of third-party extensions.

Overall, many experienced users feel that Mozilla is trying to make Firefox too similar to Chrome in order to compete against Chrome. What Mozilla refuses to accept is the fact that, if a user wants Chrome, that user will install Chrome and not Firefox.

So far, Sea Monkey has been able to avoid these Firefox deficiencies.

Comment Free Music? Yes, That "Business Model" Does Work (Score 0) 370

I listen to streaming broadcasts sent over the Internet directly by radio stations. Most of these stations are non-profit, many of them part of National Public Radio. They seem not only to be surviving but even thriving. Three of the stations are sufficiently close that I can listen to them over the "airwaves". The rest of them are available only via Internet streaming.

Of course my taste in music is mostly classical, music that is still entertaining and appreciated more than a month after it is first released. In many cases, the recordings are no longer available commercially. If the cited trend in this article is true, perhaps young listeners might learn of the majesty of Beethoven, the emotion of Tchaikovsky, the joy of Gershwin.

Comment Use SecretAgent (Score 1) 46

If you are using Firefox or SeaMonkey as your browser (both Mozilla-based), get the SecretAgent extension from https://www.dephormation.org.uk/SecretAgent/. Since I installed it in SeaMonkey, not only do many sites have trouble locating where I am, some sites cannot even determine on which continent I am located.

Comment SecretAgent Extension Conflicts with PrefBar (Score 1) 212

For Mozilla-based browsers such as Firefox and SeaMonkey, the SecretAgent extension conflicts with the PrefBar User Agent menulist.

Because some Web sites I visit are sensitive to what user agent they see, I unchecked (disabled) the "Rotate User Agent" checkbox in SecretAgent. Then, if I used the PrefBar User Agent menulist to spoof some other browser, it kept resetting to my actual user agent. Since I consider the PrefBar capability to be very important, I removed SecretAgent. The PrefBar capability was then restored.

Comment Re:New Slashdot feature: RTFM Sunday! (Score 1) 506

Install the PrefBar extension in Firefox or SeaMonkey. Enable the Restore Tab button.

By the way, accidentally closing a tab in SeaMonkey should be rare since the X to close is at the far right of the tab bar, not on the tab. Putting the X on the tab itself has proven dangerous because it is then too easy to close a tab when trying to select the adjacent tab on the right.

Submission + - Regional Concentrations of Scientists and Engineers in the United States 1

DERoss writes: The National Science Foundation has publish a research paper with the subject title, which may be found at http://www.nsf.gov/statistics/infbrief/nsf13330/. The lead paragraph contains the sentence "The three most populous states—California, Texas, and New York—together accounted for more than one-fourth of all S&E employment in the United States."

According to the 2010 census, however, those three states also contain more than one-fourth (26.5%) percent of the U.S. population. In other words, there is NO concentration beyond how the general population is concentrated.

Comment Back in the day ... (Score 4, Interesting) 46

I worked for Unisys and one of its predecessors for 24 years. At the time Unisys was created -- Burroughs did a hostile takeover of Univac -- the combined company had some 130,000 employees; and about half of its business was with the U.S. military. Now the company has about 22,800 employees and seems to have no military business. I stuck with the company even when they started treating salaried software professionals as if they were hourly assembly-line workers. I stuck with them when they imposed an 18-month salary freeze that did not apply to executive bonuses. I left when it was obvious that any manager who brought new work to our site would be fired.

Comment Why not 403? (Score 1) 255

According to Section 10.4.4 of RFC 2616, 403 means:

The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead.

Comment Leap Seconds Are Old News (Score 4, Informative) 46

Before 1972, "leaps" were fractions of a second; a UTC second (Universal Time Coordinated) did not have the same duration as a TAI second (the French acronym for International Atomic Time); and "leaps" occurred as often as four times a year. The current form of leap-seconds has been in effect since 1972. By then, software (mostly main frames) handled leap-seconds quite easily.

The reason for leap-seconds is that the earth's rotation is gradually slowing while many critical operations require precise time indicators. Thus, noon at Greenwich -- even average noon, which takes into account annual and semi-annual variations in the earth's rotation -- cannot be used. Instead, those critical operations use TAI. TAI is a uniform, never-varying time system while UTC is coordinated with noon at Greenwich. Since 1972, however, a UTC second has exactly the same duration as a TAI second; and a UTC clock ticks its seconds exactly at the same time as a TAI clock. If this continued indefinitely, noon on a UTC clock would gradually deviate from noon at Greenwich. Since 1972, if the deviation approaches a whole second, an extra second -- a leap-second -- is added to a UTC clock at the end of the last minute of either 30 June or 31 December.

All this became a problem in 2006. During the 7 years from 1 January 1999 until 1 January 2006, the slowing of the earth's rotation was so slight that there were no leap-seconds. Too many young software engineers and other technologists failed to learn about leap-seconds and thus ignored them (just the the Y2K issue was ignored until it was almost too late). A situation that was handled quite well in the 1970s, 1980s, and 1990s was no longer handled at all in new systems. But on 1 January 2006, there was indeed a leap-second. By then, many of those who were familiar with leap-seconds and how to handle them had retired (including me).

Comment None of the Above (Score 1) 587

The first computer on which I attempted to write code was the SWAC (Standards Western Automatic Computer), "Standards" meaning National Bureau of Standards (NBS). (The NBS is now the National Institute of Standards and Technology (NIST).) It would have filled my home office and had 256 words of memory (no "K", just 1, 2, 3, ... 254, 255, 256). For an entire year, it was the world's fastest digital computer.

Today, I have a PC that I can pick up and put in the trunk of my car to take to the repair shop, which I had to do this past week. It has 4 GB of memory, 16,000,000 times the memory of SWAC. It is also orders of magnitude faster.

Comment Re:Hard Copy Okay (Score 1) 329

I feel that OCR-A and OCR-B are so stylized that they are somewhat distracting. Thus, it takes more effort to read text in such fonts than reading text in (for example) Georgia or Verdana. Even my recommended Trebuchet is somewhat stylized, but I find it easier to read than either of the OCR fonts.

One way to look at this issue is whether an individual is aware that a font is "different". If so, then more concentration is required to grasp the meaning of the text, concentration to avoid distraction.

Comment Hard Copy Okay (Score 2) 329

For printing, pick a font that has no ambiguous characters. This makes OCR easier if you have to retrieve the data back into a computer. I suggest Trebuchet, in which I (upper-case eye), l (lower-case ell), and 1 (one) are distinct. Alternatively, use either the OCR-A or OCR-B font, which are not easily read by humans. Place the hard copy in a sealed envelope and store it in a bank safe-deposit box.

Also in the same safe-deposit box, store electronic copies using at least two different media (two so that, if one becomes obsolete and unreadable, the other might still be used). You might want to change the media -- or at least review them -- annually to ensure they are still useable.
