Question

Write code to establish addressability to the data referenced by the label NBR using the register r3 9.1 9.2 Use the following code segment to answer parts a through d hw42.s .data DSECT .word 0xbbbbbbbb more data instances Y: .byte0x22 Z: .half 0x33 .. . more data instances .word 0xeeeeeeee .end a. b. c. d. Write the code to load the data referenced by label X into register r4. Write the code to load the data referenced by label Y into register r5. Write the code to load the data referenced by label Z into register re. Load the same registers with the same values as parts a through c, by establishing addressability to the label DSECT only once.

Answer 1

beginning with wget 1.7, if you use -c on a file that is of equal size as the one on the server, wget will refuse to download the file and print an explanatory message. The same happens when the file is smaller on the server than locally (presumably because it was changed on the server since your last download attempt), because "continuing" is not meaningful, no download occurs. On the other hand, while using -c, any file that's bigger on the server than locally will be considered an incomplete download and only (length(remote) - length(local)) bytes will be downloaded and tacked onto the end of the local file. This behavior can be desirable in certain cases: for instance, you can use wget -c to download just the new portion that's been appended to a data collection or log file. However, if the file is bigger on the server because it's been changed, as opposed to just appended to, you'll end up with a garbled file. wget has no way of verifying that the local file is really a valid prefix of the remote file. You need to be especially careful of this when using -c in conjunction with -r, since every file will be considered as an "incomplete download" candidate. Another instance where you'll get a garbled file if you try to use -c is if you have a lame HTTP proxy that inserts a "transfer interrupted" string into the local file. In the future a "rollback" option may be added to deal with this case. Note that -c only works with FTP servers and with HTTP servers that support the "Range" header.

--progress=type

Select the progress indicator you want to use. Legal indicators are "dot" and "bar". The "bar" indicator is used by default. It draws an ASCIIprogress bar graphics (a.k.a "thermometer" display) indicating the status of retrieval. If the output is not a TTY, the "dot" bar will be used by default. Use --progress=dot to switch to the "dot" display. It traces the retrieval by printing dots on the screen, each dot representing a fixed amount of downloaded data. When using the dotted retrieval, you may also set the style by specifying the type as dot:style. Different styles assign different meaning to one dot. With the "default" style each dot represents 1 K, there are ten dots in a cluster and 50 dots in a line. The "binary" style has a more "computer"-like orientation: 8 K dots, 16-dots clusters and 48 dots per line (which makes for 384 K lines). The "mega" style is suitable for downloading very large files; each dot represents 6 4K retrieved, there are eight dots in a cluster, and 48 dots on each line (so each line contains 3 M). Note that you can set the default style using the progresscommand in .wgetrc. That setting may be overridden from the command line. The exception is that, when the output is not a TTY, the "dot" progress will be favored over "bar". To force the bar output, use --progress=bar:force.
