Walking on Water

2009-07-16T15:53:00.003+05:30

Brown basilisk lizard

When you talk about walking on water, you’re in the territory of myth, magic and religious miracles, right? Wrong. What’s more, it’s not just little critters like pond skaters that can perform this amazing exploit; an animal as large as two feet long also has the dancing feet to pull off the incredible feat too. Dim the lights please as we introduce the basilisk lizard – aka the Jesus Lizard. Real rock n’ roll.

Are you talkin’ to me? Male green basilisk

Photo: Edgley Cesar

John Lennon famously got swamped in controversy when he was quoted saying the Beatles were “more popular than Jesus”, but this superstar of an animal lets its actions do the talking. Named after Christianity’s central figure because of a shared reputation for being able to do what others need yachts and jet skis to do, the Jesus Lizard can more accurately be said to run across the water’s surface layer.

Got to get to the tree, got to get to the tree: Miracle in motion

Photo via silberman

Rather than scaring disciples with this singular talent, the Jesus Lizard uses it to flee from predators – and at some speed, sprinting at about 5 feet per second, before gravity kicks in and it turns to its none too shoddy swimming skills. It can skim along on top for distances of 15 feet or more, despite having a weight greater than the water’s surface tension can support. But how, we hear you gasp in wonder?

…Well, I’m the only one here: Female green basilisk

Photo: Stevenj

The secret of the Jesus Lizard’s trick are its large hind feet, with flaps of skin between each toe similar to the webbed tootsies of a frog. These help support the basilisk, increasing its surface area and creating a tiny air pocket that stops it from sinking as long as it maintains its momentum. Running upright, often using only its back legs, the basilisk might be dubbed the Michael Johnson lizard.

Found throughout the tropical rainforests of Central America wherever there is water nearby, the Jesus Lizard is actually at least three species of lizard: the common, green, and brown basilisk. All have an omnivorous diet that includes plants, fruit, insects and small animals like rodents, lizards and fish, and all must be wary of predators such as snakes, birds of prey and larger reptiles and mammals.

Just can’t reach… A basilisk at the end of a run

Photo: Richard Sprague

When the basilisk senses danger, its water-walking instinct takes over and it plops into the water…

Anyone who has seen a show by the band The Jesus Lizard will know it’s a minor miracle how singer David Yow manages to keep yowling as he repeatedly stage dives and surfs over the sea of people in the crowd. But this phenomenon falls flat in comparison with the living miracle that is the real Jesus lizard – and that’s gospel truth.

Zoho Writer 2.0: A User Interface That’s More User Friendly

2009-03-11T18:53:00.001+05:30

There is very little reason to depend on a hard drive-based application for your word processing needs these days. Google Docs provides everything most users will ever need; you already have it if you have a Gmail account, and it works offline, thanks to Google Gears. Another solution, Zoho Writer, which also works offline thanks to Gears, just got a major interface overhaul in its 2.0 incarnation, and now is more poised than ever to provide a complete alternative to Office and other similar programs.

The problem with Zoho, until now, has been one of constant improvement. That may not seem like a problem at all, but when that improvement involves adding more and more features, but keeping the interface the same, it can get a little unruly. The new redesign tries to make sure Zoho doesn’t overwhelm you visually, which in turn makes it easier to work with.

The old Zoho Writer menu

While some liked the old UI, I found it too cluttered, because I normally like to edit in full screen, and like as little chrome as possible in my browsers. The changes to the top menu give you a bit more room, but more importantly, they group and hide a lot of commands so you aren’t left feeling crowded. The new “MenuTab” feature groups similar commands under general headings. You can access these commands either by clicking the tab, which changes the button set available on your toolbar (much like Microsoft’s “Ribbon” UI for Office) or by clicking the little arrow next to them, which opens a drop-down menu without changing your toolbar.

The new Zoho Writer 2.0 "MenuTab" interface

It makes sense, and it suits multiple tastes. You’ll be comfortable if you’re used to working with Office, or if you’re used to working with drop-down menus like you’ll find in a lot of web apps. Zoho plans to use MenuTab in all of its other applications in the future, too, so even if you don’t like it, plan on getting used to it!

I won’t go into detail about Zoho Writer, since we’ve covered it before. It’s not new, but I still love Zoho’s tabbed management of open documents. I much prefer it to Google’s opening of new browser tabs for each document, although that makes much more sense when you take into account Google Chrome’s handling of each tab as a separate process. And I still miss Google’s full-screen edit mode too much to make a permanent switch.

Still, if you’re a Zoho user, or if you tried it out before but didn’t like it because of the interface, Zoho Writer 2.0 gives you ample reason to take it out for a second spin.

10 Status Code Definitions

2009-02-15T12:05:00.001+05:30

Each Status-Code is described below, including a description of which method(s) it can follow and any metainformation required in the response.

10.1 Informational 1xx

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions.

A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent.

Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a

proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).)

10.1.1 100 Continue

The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code.

10.1.2 101 Switching Protocols

The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response.

The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features.

10.2 Successful 2xx

This class of status code indicates that the client's request was successfully received, understood, and accepted.

10.2.1 200 OK

The request has succeeded. The information returned with the response is dependent on the method used in the request, for example:

GET an entity corresponding to the requested resource is sent in the response;

HEAD the entity-header fields corresponding to the requested resource are sent in the response without any message-body;

POST an entity describing or containing the result of the action;

TRACE an entity containing the request message as received by the end server.

10.2.2 201 Created

The request has been fulfilled and resulted in a new resource being created. The newly created resource can be referenced by the URI(s) returned in the entity of the response, with the most specific URI for the resource given by a Location header field. The response SHOULD include an entity containing a list of resource characteristics and location(s) from which the user or user agent can choose the one most appropriate. The entity format is specified by the media type given in the Content-Type header field. The origin server MUST create the resource before returning the 201 status code. If the action cannot be carried out immediately, the server SHOULD respond with 202 (Accepted) response instead.

A 201 response MAY contain an ETag response header field indicating the current value of the entity tag for the requested variant just created, see section 14.19.

10.2.3 202 Accepted

The request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place. There is no facility for re-sending a status code from an asynchronous operation such as this.

The 202 response is intentionally non-committal. Its purpose is to allow a server to accept a request for some other process (perhaps a batch-oriented process that is only run once per day) without requiring that the user agent's connection to the server persist until the process is completed. The entity returned with this response SHOULD include an indication of the request's current status and either a pointer to a status monitor or some estimate of when the user can expect the request to be fulfilled.

10.2.4 203 Non-Authoritative Information

The returned metainformation in the entity-header is not the definitive set as available from the origin server, but is gathered from a local or a third-party copy. The set presented MAY be a subset or superset of the original version. For example, including local annotation information about the resource might result in a superset of the metainformation known by the origin server. Use of this response code is not required and is only appropriate when the response would otherwise be 200 (OK).

10.2.5 204 No Content

The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

If the client is a user agent, it SHOULD NOT change its document view from that which caused the request to be sent. This response is primarily intended to allow input for actions to take place without causing a change to the user agent's active document view, although any new or updated metainformation SHOULD be applied to the document currently in the user agent's active view.

The 204 response MUST NOT include a message-body, and thus is always terminated by the first empty line after the header fields.

10.2.6 205 Reset Content

The server has fulfilled the request and the user agent SHOULD reset the document view which caused the request to be sent. This response is primarily intended to allow input for actions to take place via user input, followed by a clearing of the form in which the input is given so that the user can easily initiate another input action. The response MUST NOT include an entity.

10.2.7 206 Partial Content

The server has fulfilled the partial GET request for the resource. The request MUST have included a Range header field (section 14.35) indicating the desired range, and MAY have included an If-Range header field (section 14.27) to make the request conditional.

The response MUST include the following header fields:

      - Either a Content-Range header field (section 14.16) indicating
        the range included with this response, or a multipart/byteranges
        Content-Type including Content-Range fields for each part. If a
        Content-Length header field is present in the response, its
        value MUST match the actual number of OCTETs transmitted in the
        message-body.

      - Date

      - ETag and/or Content-Location, if the header would have been sent
        in a 200 response to the same request

      - Expires, Cache-Control, and/or Vary, if the field-value might
        differ from that sent in any previous response for the same
        variant

If the 206 response is the result of an If-Range request that used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers. If the response is the result of an If-Range request that used a weak validator, the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers. Otherwise, the response MUST include all of the entity-headers that would have been returned with a 200 (OK) response to the same request.

A cache MUST NOT combine a 206 response with other previously cached content if the ETag or Last-Modified headers do not match exactly, see 13.5.4.

A cache that does not support the Range and Content-Range headers MUST NOT cache 206 (Partial) responses.

10.3 Redirection 3xx

This class of status code indicates that further action needs to be taken by the user agent in order to fulfill the request. The action required MAY be carried out by the user agent without interaction with the user if and only if the method used in the second request is GET or HEAD. A client SHOULD detect infinite redirection loops, since such loops generate network traffic for each redirection.

      Note: previous versions of this specification recommended a
      maximum of five redirections. Content developers should be aware
      that there might be clients that implement such a fixed
      limitation.

10.3.1 300 Multiple Choices

The requested resource corresponds to any one of a set of representations, each with its own specific location, and agent- driven negotiation information (section 12) is being provided so that the user (or user agent) can select a preferred representation and redirect its request to that location.

Unless it was a HEAD request, the response SHOULD include an entity containing a list of resource characteristics and location(s) from which the user or user agent can choose the one most appropriate. The entity format is specified by the media type given in the Content- Type header field. Depending upon the format and the capabilities of

the user agent, selection of the most appropriate choice MAY be performed automatically. However, this specification does not define any standard for such automatic selection.

If the server has a preferred choice of representation, it SHOULD include the specific URI for that representation in the Location field; user agents MAY use the Location field value for automatic redirection. This response is cacheable unless indicated otherwise.

10.3.2 301 Moved Permanently

The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs. Clients with link editing capabilities ought to automatically re-link references to the Request-URI to one or more of the new references returned by the server, where possible. This response is cacheable unless indicated otherwise.

The new permanent URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s).

If the 301 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued.

      Note: When automatically redirecting a POST request after
      receiving a 301 status code, some existing HTTP/1.0 user agents
      will erroneously change it into a GET request.

10.3.3 302 Found

The requested resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field.

If the 302 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued.

      Note: RFC 1945 and RFC 2068 specify that the client is not allowed
      to change the method on the redirected request.  However, most
      existing user agent implementations treat 302 as if it were a 303
      response, performing a GET on the Location field-value regardless
      of the original request method. The status codes 303 and 307 have
      been added for servers that wish to make unambiguously clear which
      kind of reaction is expected of the client.

10.3.4 303 See Other

The response to the request can be found under a different URI and SHOULD be retrieved using a GET method on that resource. This method exists primarily to allow the output of a POST-activated script to redirect the user agent to a selected resource. The new URI is not a substitute reference for the originally requested resource. The 303 response MUST NOT be cached, but the response to the second (redirected) request might be cacheable.

The different URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s).

      Note: Many pre-HTTP/1.1 user agents do not understand the 303
      status. When interoperability with such clients is a concern, the
      302 status code may be used instead, since most user agents react
      to a 302 response as described here for 303.

10.3.5 304 Not Modified

If the client has performed a conditional GET request and access is allowed, but the document has not been modified, the server SHOULD respond with this status code. The 304 response MUST NOT contain a message-body, and thus is always terminated by the first empty line after the header fields.

The response MUST include the following header fields:

      - Date, unless its omission is required by section 14.18.1

If a clockless origin server obeys these rules, and proxies and clients add their own Date to any response received without one (as already specified by [RFC 2068], section 14.19), caches will operate correctly.

      - ETag and/or Content-Location, if the header would have been sent
        in a 200 response to the same request

      - Expires, Cache-Control, and/or Vary, if the field-value might
        differ from that sent in any previous response for the same
        variant

If the conditional GET used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers. Otherwise (i.e., the conditional GET used a weak validator), the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers.

If a 304 response indicates an entity not currently cached, then the cache MUST disregard the response and repeat the request without the conditional.

If a cache uses a received 304 response to update a cache entry, the cache MUST update the entry to reflect any new field values given in the response.

10.3.6 305 Use Proxy

The requested resource MUST be accessed through the proxy given by the Location field. The Location field gives the URI of the proxy. The recipient is expected to repeat this single request via the proxy. 305 responses MUST only be generated by origin servers.

      Note: RFC 2068 was not clear that 305 was intended to redirect a
      single request, and to be generated by origin servers only.  Not
      observing these limitations has significant security consequences.

10.3.7 306 (Unused)

The 306 status code was used in a previous version of the specification, is no longer used, and the code is reserved.

10.3.8 307 Temporary Redirect

The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field.

The temporary URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s) , since many pre-HTTP/1.1 user agents do not understand the 307 status. Therefore, the note SHOULD contain the information necessary for a user to repeat the original request on the new URI.

If the 307 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued.

10.4 Client Error 4xx

The 4xx class of status code is intended for cases in which the client seems to have erred. Except when responding to a HEAD request, the server SHOULD include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. These status codes are applicable to any request method. User agents SHOULD display any included entity to the user.

If the client is sending data, a server implementation using TCP SHOULD be careful to ensure that the client acknowledges receipt of the packet(s) containing the response, before the server closes the input connection. If the client continues sending data to the server after the close, the server's TCP stack will send a reset packet to the client, which may erase the client's unacknowledged input buffers before they can be read and interpreted by the HTTP application.

10.4.1 400 Bad Request

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

10.4.2 401 Unauthorized

The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.47) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8). If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity might include relevant diagnostic information. HTTP access authentication is explained in "HTTP Authentication: Basic and Digest Access Authentication" [43].

10.4.3 402 Payment Required

This code is reserved for future use.

10.4.4 403 Forbidden

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.

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.

10.4.6 405 Method Not Allowed

The method specified in the Request-Line is not allowed for the resource identified by the Request-URI. The response MUST include an Allow header containing a list of valid methods for the requested resource.

10.4.7 406 Not Acceptable

The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.

Unless it was a HEAD request, the response SHOULD include an entity containing a list of available entity characteristics and location(s) from which the user or user agent can choose the one most appropriate. The entity format is specified by the media type given in the Content-Type header field. Depending upon the format and the capabilities of the user agent, selection of the most appropriate choice MAY be performed automatically. However, this specification does not define any standard for such automatic selection.

      Note: HTTP/1.1 servers are allowed to return responses which are
      not acceptable according to the accept headers sent in the
      request. In some cases, this may even be preferable to sending a
      406 response. User agents are encouraged to inspect the headers of
      an incoming response to determine if it is acceptable.

If the response could be unacceptable, a user agent SHOULD temporarily stop receipt of more data and query the user for a decision on further actions.

10.4.8 407 Proxy Authentication Required

This code is similar to 401 (Unauthorized), but indicates that the client must first authenticate itself with the proxy. The proxy MUST return a Proxy-Authenticate header field (section 14.33) containing a challenge applicable to the proxy for the requested resource. The client MAY repeat the request with a suitable Proxy-Authorization header field (section 14.34). HTTP access authentication is explained in "HTTP Authentication: Basic and Digest Access Authentication" [43].

10.4.9 408 Request Timeout

The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time.

10.4.10 409 Conflict

The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough

information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

10.4.11 410 Gone

The requested resource is no longer available at the server and no forwarding address is known. This condition is expected to be considered permanent. Clients with link editing capabilities SHOULD delete references to the Request-URI after user approval. If the server does not know, or has no facility to determine, whether or not the condition is permanent, the status code 404 (Not Found) SHOULD be used instead. This response is cacheable unless indicated otherwise.

The 410 response is primarily intended to assist the task of web maintenance by notifying the recipient that the resource is intentionally unavailable and that the server owners desire that remote links to that resource be removed. Such an event is common for limited-time, promotional services and for resources belonging to individuals no longer working at the server's site. It is not necessary to mark all permanently unavailable resources as "gone" or to keep the mark for any length of time -- that is left to the discretion of the server owner.

10.4.12 411 Length Required

The server refuses to accept the request without a defined Content- Length. The client MAY repeat the request if it adds a valid Content-Length header field containing the length of the message-body in the request message.

10.4.13 412 Precondition Failed

The precondition given in one or more of the request-header fields evaluated to false when it was tested on the server. This response code allows the client to place preconditions on the current resource metainformation (header field data) and thus prevent the requested method from being applied to a resource other than the one intended.

10.4.14 413 Request Entity Too Large

The server is refusing to process a request because the request entity is larger than the server is willing or able to process. The server MAY close the connection to prevent the client from continuing the request.

If the condition is temporary, the server SHOULD include a Retry- After header field to indicate that it is temporary and after what time the client MAY try again.

10.4.15 414 Request-URI Too Long

The server is refusing to service the request because the Request-URI is longer than the server is willing to interpret. This rare condition is only likely to occur when a client has improperly converted a POST request to a GET request with long query information, when the client has descended into a URI "black hole" of redirection (e.g., a redirected URI prefix that points to a suffix of itself), or when the server is under attack by a client attempting to exploit security holes present in some servers using fixed-length buffers for reading or manipulating the Request-URI.

10.4.16 415 Unsupported Media Type

The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method.

10.4.17 416 Requested Range Not Satisfiable

A server SHOULD return a response with this status code if a request included a Range request-header field (section 14.35), and none of the range-specifier values in this field overlap the current extent of the selected resource, and the request did not include an If-Range request-header field. (For byte-ranges, this means that the first- byte-pos of all of the byte-range-spec values were greater than the current length of the selected resource.)

When this status code is returned for a byte-range request, the response SHOULD include a Content-Range entity-header field specifying the current length of the selected resource (see section 14.16). This response MUST NOT use the multipart/byteranges content- type.

10.4.18 417 Expectation Failed

The expectation given in an Expect request-header field (see section 14.20) could not be met by this server, or, if the server is a proxy, the server has unambiguous evidence that the request could not be met by the next-hop server.

10.5 Server Error 5xx

Response status codes beginning with the digit "5" indicate cases in which the server is aware that it has erred or is incapable of performing the request. Except when responding to a HEAD request, the server SHOULD include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. User agents SHOULD display any included entity to the user. These response codes are applicable to any request method.

10.5.1 500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

10.5.2 501 Not Implemented

The server does not support the functionality required to fulfill the request. This is the appropriate response when the server does not recognize the request method and is not capable of supporting it for any resource.

10.5.3 502 Bad Gateway

The server, while acting as a gateway or proxy, received an invalid response from the upstream server it accessed in attempting to fulfill the request.

10.5.4 503 Service Unavailable

The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.

      Note: The existence of the 503 status code does not imply that a
      server must use it when becoming overloaded. Some servers may wish
      to simply refuse the connection.

10.5.5 504 Gateway Timeout

The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server specified by the URI (e.g. HTTP, FTP, LDAP) or some other auxiliary server (e.g. DNS) it needed to access in attempting to complete the request.

      Note: Note to implementors: some deployed proxies are known to
      return 400 or 500 when DNS lookups time out.

10.5.6 505 HTTP Version Not Supported

The server does not support, or refuses to support, the HTTP protocol version that was used in the request message. The server is indicating that it is unable or unwilling to complete the request using the same major version as the client, as described in section 3.1, other than with this error message. The response SHOULD contain an entity describing why that version is not supported and what other protocols are supported by that server.

HTTP Error 304 - Not modified

2009-02-15T12:04:00.001+05:30

Introduction

This does not really indicate an error, but rather indicates that the resource for the requested URL has not changed since last accessed or cached. The 304 status code should only be returned if allowed by the client (e.g. your Web browser or our CheckUpDown robot). The client specifies this in the HTTP data stream sent to your Web server e.g. via If_Modified_Since headers in the request.
Systems that cache or index Web resources (such as search engines) often use the 304 response to determine if the information they previously gathered for a particular URL is now out-of-date.

304 errors in the HTTP cycle

Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with your Web server:
Obtain an IP address from the IP name of your site (your site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
Open an IP socket connection to that IP address.
Write an HTTP data stream through that socket.
Receive an HTTP data stream back from your Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receives an HTTP status code that it recognises as '304'.

Resolving 304 errors - general

You should never see this error in your Web browser. It should simply present the Web page from its cache - because it believes the page has not changed since it was last cached. If your client is not a Web browser, then it should equally be able to present the page from a cache. If unable to do so, it is not using the If_Modified_Since or related headers correctly.

Resolving 304 errors - CheckUpDown

You should never see this error at all for the CheckUpDown service. It indicates defective programming by us or the developers of your Web server software. Either we or they are not respecting HTTP protocols completely.
The 304 status code should only be returned if we allow it in the HTTP data stream we send to your Web server. Because we keep no records of the actual content of your URL Web page, we specifically disallow the 304 response in the HTTP data stream we send.
So if your Web server implements the HTTP protocol properly, it should never send an 304 status code back to us. This response is not what we expect, so we actively report it as an error even though it does not necessarily mean that your Web site is down.
Please contact us directly (email preferred) whenever you encounter 304 errors. Only we can resolve them for you. Unfortunately this may take some time, because we have to analyse the underlying HTTP data streams and may have to liaise with your ISP and the vendor of your Web server software to agree the exact source of the error.

remove CTRL-M characters

2009-02-10T14:16:00.001+05:30

remove CTRL-M characters from a file in UNIX

Something useful yet many don't know about it:

Using sed (the stream editor)- try this:
sed -e "s/^M//" FileName > NewFileName

To get ^M you hold down the CTRL key, press V then while still holding CTRL, press M.

While using vi:
% vi filename

While in vi and vim, hit : to get into command mode, then type:
:%s/^M//g

While in Emacs, go to the beginning of the document and
Type:
M-x replace-string RET C-q C-m RET RET

where "RET" means press-the-return-key and C-q and C-m mean hold-the-CTRL-key-and press-the-m-(or q)-key.

Best Little Co : Zoho

2008-12-23T11:35:00.001+05:30

Best LittleCo of 2008 & Most Promising for 2009

Every year we do a review of the top Internet companies, to identify the ones that had the biggest impact. Last week we announced that Apple was our choice for Best BigCo of 2008. Today we're announcing Best LittleCo and Most Promising Company, as selected by the ReadWriteWeb writers. There were a number of small companies that were in contention for Best LittleCo: FriendFeed, Meebo, and last year's winner Twitter would all have been deserving winners. In the end, we chose a 'little company that could' in the enterprise space. Our pick for Most Promising is something you could be using a lot on your mobile phone next year...

This is the 5th year we've done this and many of the small companies we choose each year go onto much bigger things. Here's a quick look back at previous winners:

In 2004Ludicorp, creators of Flickr, was named Best LittleCo and Feedburner Most Promising. Both of course have since been acquired (by Yahoo! and Google respectively).
In 2005 37Signals was Best LittleCo and Memeorandum (now Techmeme) and Digg were joint Most Promising.
In 2006YouTube was Best LittleCo and Sharpcast Most Promising.
In 2007Twitter got Best BigCo and (in a bit of a break from tradition) we named"the open source movement" as most promising - a loose-knit group that aims to make a huge impact by tying all Web companies together. Last year we thought there was no single Web company that was more promising, and we have probably been proven right as our Best Web Platforms 2008 post showed (OpenSocial, Android, Mozilla Weave, Fire Eagle, ...).

Now let's find out who is ReadWriteWeb's Best LittleCo of 2008...

Best LittleCo of 2008: Zoho

We felt that Web Office vendor Zoho best represented the 'LittleCo' ethos this year, due to its David vs Goliath effort in competing head on with products from several very large companies: Microsoft Office, Google Apps, Salesforce.com's core CRM platform.

Zoho not only competed with these bigcos, they were innovative and scrappy about it. And in a year that will be remembered for the economic downturn, Zoho is a reminder to us all that we can work ourselves out of a down economy.

Zoho made two of our year-end Top 10 Products list - in the International category and in the Enterprise catagory. It is an Indian startup that offers a number of office tools, project management software and CRM solutions. It made serious advances with its office productivity suite during 2008, reaching a milestone of 1 million users in August this year.

Some of the specific highlights this year include: updating Writer at the beginning of 2008 to include support for the DocX file format, along with several other features; adding support for Visual Basic compatible macros to Zoho Sheet in April, then macro record and playback four months later; releasing a marketplace in September; Zoho Mail emerging from private beta in October, while offering offline support via Google Gears.

Our one note of caution with Zoho is that, as you can see from the above screenshot, it has so many products that it potentially spreads itself too thin. Some of its products show a lack of depth as a result - we focused on some of those issues in a post in September. So we're not claiming Zoho has the Web Office market cracked, just as Twitter had some issues last year when we chose it as our Best LittleCo. But overall, we applaud Zoho for its continued innovation and for competing effectively against the big guns!
