by The SunPRINCE Andrew’s pal Ghislaine Maxwell will speak to the FBI about their links to paedo Jeffrey Epstein.
Sources said the sex slaver’s “madam”, 57, aims to emerge from hiding within days.
Sources say she is set to defend herself and the prince.
She has told pals she thinks the picture of them with Virginia Roberts, who claims she had sex with Andrew when she was 17, may have been doctored.
It was said to have been taken at her London home in March 2001.
“Ghislaine thinks there are a lot of problems with the picture and it is very fishy.

This components purpose is to create a slideshow of images using a given images source string: images
.
In order to create the nice opacity switching effect between the images we use a function where we switch between an opacity
of 1 or 0 this way:
At the two end, 0% and 100%, and when the animation time expires(at the moment we use 10), then the opacity
is considered 0 and in any other moment of the animation the opacity
is 1.
Because some images may not be the same size we made a function that will resize the height of the slideshow every time it is necessary.
If the title

or if the element has any HTML children, then an auxiliary div container is created with content
class and all given info in the three at question.
If there are any actions (any children) then a slot will be created (inside a actions

Michael Collins (1996) A film review by Steve Rhodes Copyright 1996 Steve Rhodes
RATING (0 TO ****): ***
Quick, name some good films about the American revolution? Hmm, couldn't name any? For those of you who incorrectly listed REVOLUTION (1985), remember I said "good" films. Granted the Internet Movie Data Base does also list a few obscure, older ones, but basically there aren't any.
Thanks to director Neil Jordan (MONA LISA, THE CRYING GAME, and INTERVIEW WITH A VAMPIRE), there is a good one about the "Irish" revolution. Taken from the perspective of a key Irish terrorist and later peace broker, the film is known simply as MICHAEL COLLINS.
MICHAEL COLLINS is an excellent, but frustrating film. The acting is brilliant as is the direction. The film's downfall lies in the script, also by Neil Jordan. Tactically the script works, but not strategically.
After a three paragraph written introduction to past Irish history, the viewer is thrust into the thick of the 1916 Easter Rising where the battle is fully engaged. Certainly Irish historians will have no problems, but I posit that average movie goers will feel like they turned on the TV and found themselves starting off in the middle of a great mini-series with only a few sound bites from the narrator to give them the necessary context and motivation. There is fat in the show that could have been trimmed in favor of more historical perspective in the beginning.
Similarly, most of MICHAEL COLLINS leads up to the signing of the treaty with England, but it does not end cleanly there. Jordan decides he must show all of the events after that up until Collins death. The problem is that the show is already about two hours long at that point so he rushes through a sketchy outline version of the end that leaves you exhausted and confused. Quick incident after incident are thrown at the audience in a montage that feels like we are see nothing more than the trailers for MICHAEL COLLINS PART II.
I have to get one final problem out of the way so I can concentrate on the positive aspects of what is at its core an excellent movie. Hollywood decided that they had to have a sex interest in the film so they signed Julia Roberts to play the role of Michael Collins's girlfriend Kitty Kiernan.
Without exception, the film would be stronger if every scene Roberts was in, would have been left on the cutting room floor. The show's great momentum grinds to a halt every time she appears. Her part is the fat I alluded to earlier. Maybe they could have left her name on the marquee and just put her picture on Collins's desk, but not forced her to deliver a bunch of meaningless lines, including my favorite bit of drivel, "so which one of you gunslingers is going to ask me to dance." Roberts should have politely collected her check and left.
Now onto the brilliance of the rest of the picture.
"What happens next time?" asks Harry Boland (Aidan Quinn) as they surrender at the end of the Easter Rising. "Next time, Harry, we won't play by their rules. We'll play by our own," reassures Michael Collins (Liam Neeson) with plans to switch to terrorism and away from open warfare.
When Eamon De Valera (Alan Rickman) is captured we see him writing a letter from prison with the sun streaming in to bless writings. Chris Menges's emotive cinematography makes him look like St. Francis composing his pieties.  The cinematography is Academy Award nomination material as is the acting by Neeson and by Stephen Rea as Ned Broy, who was Collins's personal spy in the British intelligence service in Dublin.
Neeson's portrayal of Collins as a terrorist's terrorist is unflinching. He is willing to kill anyone at any time to support the revolution. His only concern is not to waste precious bullets. Nevertheless, Neeson is so attractive and compelling, that regardless of whose side you were on when entering the theater, you are likely to side with Collins during the show. Neeson gives such an involving performance that will find yourself pleased every time another British soldier or intelligence officer is murdered.
Collins wants to wage his war with fear so he starts a mass campaign of slaughter against the British rulers, specially the British "G-men" in Dublin. There are British who are sympathetic to the Irish cause. While in Lincoln prison back in England, De Valera is told by the chaplain (Aidan Grennell) that, "I can't understand your politics, but I appreciate your integrity."
The show argues effectively that De Valera had little integrity and that he was the Machiavellian figure of the Irish revolution. Specifically, it claims, among other things, that he sent Collins rather than himself to negotiate with Britain because he knew that the best result that could be hoped for would be derided by the Irish people. If someone else could be blamed, then his hands would be clean. Rickman gives a wonderfully slimy performance.
Collins is drawn as a complex man who proclaims, "I want peace and quiet.
To make sure you take the Irish side, the film includes frequent scenes of torture and murder by the British forces in Dublin. Typical of the G-men lines while torturing is the one where they say, "The problem with the Irish is that they'll sing at the drop of a hat, but ask them to talk and they won't."
I accepted the film lock, stock, and barrel as accurate until a scene where the British troops drive an armored car into a rugby match for no reason and begin mowing down innocent people in the stands with machine guns. After that dubious bit of historical accuracy, I begin to question all of my previous assumptions about the film. Maybe the incident did happen in exactly that way, but I find it a bit hard to believe.
MICHAEL COLLINS runs 2:13, which is too short for its attempted scope, but the film would have been better if it were more tightly focused in which case it should have been shorter. The movie has an R rating.  The show should be fine for teenagers. Although the picture could and should have been much better, I liked MICHAEL COLLINS and recommend it to you. Although it is uneven, I average out its rating to ***.
**** = One of the top few films of this or any year. A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show.  Totally unbearable.

Kids’ Show Baghch-e-Simsim Launches 7th Season
In the new season of Baghch-e-Simsim, the Afghan ‘Sesame Street,’ children will be encouraged to learn about compatibility and culture along with school lessons.
by Fariba AramTOLO television on Wednesday opens the 7th season of the Baghch-e-Simsim children’s program in Kabul.
Officials at the television and radio program in Afghanistan say the program will encourage pre-school and elementary school children to learn more.
Baghch-e-Simsim is an Afghan variation of the well-known US series "Sesame Street," and has been aired on TOLO and Lemar for six years.
The Baghch-e-Simsim series is a children's education program that has a large following among Afghan citizens.
Zari and Zeerak are the two characters who star in the show, and in 2016, Zari - a six-year-old Afghan girl - was added as a character.
Sheema Sengupta, a UNICEF representative, speaking on World Children’s Day, praised the program and said it will be useful for children.
“’Sesame Street’ gives voice and participation to children and that is so important and I’m obviously not 13 years old, so when I was growing up there was "Sesame Street" but there was no convention on the rights of the child, but you know growing up and getting our voices and knowing what we speak about, and what we should speak about, even in a multi-racial country like Malaysia it was, you know, quite a different realization almost.”


This is the first PC I built for myself! I collected the parts after Christmas of 2013. Considering my budget, I was thrilled to get over 6.5 years of use out of it! I used it for school work (and certainly never played games on it, ever. Seriously. (Maybe.)) and personal projects in my free time. To keep it alive for so long, I made a few upgrades over the years. This PC was certainly a fun project and hobby, and I learned quite a bit building and using it too. Although I possibly had even more fun building my new PC, I will always remember all my late nights of homework (not gaming) that I spent using this computer.
Here are a few shots of my PC in its initial state, long ago:
Later I upgraded my graphics card, RAM, CPU cooler, and added numerous storage drives:


How to improve your credit score
A credit score is essentially a tool that lets lenders know how reliable you are.
Which means – if you want to borrow money in the form of loans, finance or a mortgage, your score needs to be decent.
Step one is to work out how to actually check your credit score (it’s really not difficult). Step two is understanding what your score is, and working towards improving it.
If your credit score is on the lower side, that’s not necessarily a reason to panic. There are plenty of ways to improve your rating – but first you need understand exactly why it matters.
‘Credit scores predict the likelihood you’ll pay your credit on time in the future based on how you’ve managed any credit in the past, which is summarised in your credit report,’ explains James Jones, head of consumer affairs at Experian.
Advertisement Advertisement
‘Your credit score is important as it helps new lenders decide whether they want you as a customer.’
James says the better your score, the more likely you are to be accepted for a wide range of accounts. This includes financial products like loans and credit cards and other common household bills such as monthly phone and energy contracts.
‘As well as the key to being accepted for these accounts, a good score can be kind to your pocket as it will increase your chances of securing the best deals, such as the headline interest rates, which are often reserved for the top scorers.’
James says that people should think of their credit report as their financial CV.
‘You wouldn’t apply for a job and let an employer look at your CV without first checking to make sure it’s up to date and paints the best picture of your suitability for the role – so don’t apply for credit before giving similar attention to your credit report.
‘Sometimes there are really easy ways to make it shine.’
James would always encourage people to check their credit score to find out where they stand, as he thinks that’s always the best starting point for improvement.
‘In terms of improving your score going forwards, things like getting on the electoral roll, keeping your card balances low, and not making too many credit applications in a short space of time, can all help you grow your score and unlock better and cheaper deals in the future,’ adds James.

How to improve your credit score
James offers some practical tips for improving your credit score – the points he references are based on the Experian Credit Score, which we explain further down.
Register on electoral roll at your current address
Have your say in local and national elections and help build your financial profile.
As well as helping lenders confirm your name and address, being on the electoral roll contributes up to 50 points to your Experian Credit Score because it’s seen as a sign of stability and reliability.
Regularly check your credit report and ask for any errors to be corrected
A single late payment can wipe 130 points off your credit score, so make sure your report reflects the facts. If you spot an error, ask the agency to raise a dispute for you.
Keep any credit card balances as low as possible
Using a credit card wisely can really help boost your credit score, but do be careful because cards can be expensive if you build up debt on them.
Repaying anything you borrow in full each month will mean you pay no interest.
For example, keeping card balances below 30% of the limit can gain 90 points.
Build up your financial track record
Lenders like to see a proven track record of responsible credit management, so get a bank account and try to get your name on some of the household bills (energy, water, broadband etc), making sure that, even if these are shared with housemates, your monthly payments are always made on time.
Advertisement
Make your rent count
For tenants, consider registering with a firm like Canopy or Credit Ladder to have your rent payments reported to Experian and included in your credit history (and soon your credit score).
Get credit for developing a savings habit
Fin tech Loqbox can help you save for the future and give your credit score a boost in the process.
Let your credit history mature
While it’s sensible to shop around from time to time to make sure you’re getting the best deals, it will help your credit score if you let some of your credit accounts mature. For example, holding the same credit card for five years can add 20 points to your Experian Credit Score.
Plan and limit applications for new credit
Space out any credit applications you make and shop around using eligibility-checking services. That way, you’ll only apply for deals you’re likely to get and avoid collecting multiple ‘hard’ search footprints.
Not applying for any new credit for six months can boost your Experian score by 50 points. It’s basically about not being needy.
Check your eligibility
Use an eligibility service to shop around and apply for credit, such as at co.uk.
We can show you which deals you’re likely be accepted for, without affecting your credit score. Importantly, this can include pre-approved deals and also guaranteed interest rates, based on your actual circumstances, greatly removing the guesswork.
How does the Experian Credit Score work? The Experian Credit Score is our public-facing score which runs on a scale of 0-999. It is provided as a guide to how lenders might interpret the information on your Experian Credit Report. But it is a guide and no lenders actually see it, although it does align with how many lenders score credit report data. We give everyone a free Experian online account so they can track their score each month. Our score bands are as follows: Very Poor 0 – 560 Poor 561 – 720 Fair 721 – 880 Good 881 – 960 Excellent 961 – 999 James Jones, Experian
Advertisement
Your score can make you better off
James says that a high credit score will help you qualify for credit and help you secure the best ‘headline’ deals, potentially saving you lots of money.
This is because not everyone gets the cheapest advertised interest rate.
‘Our research suggests that improving your credit score by one score band could see the APRs available to you fall by at least 2% on average,’ says James.
‘So, if someone improves their Experian Credit Score from Poor to Fair, we estimate that they could save an average of £381 on a four-year loan of £6,000, as they would likely be paying a lower interest rate.’
We like the sound of that.

For the time being, there isn't much information on analogue formats, but I will be adding more stuff as I come across it. Unless noted, all information applies to PAL 625/50 versions. I'm omitting SECAM on purpose, because it's rarely used for studio work anyway.
Many of the figures have been extracted from manufacturers' brochures and do not necessarily represent the best a given recording format can offer. Nevertheless, they should be pretty close.
And to keep things in perspective, let me remind you that 16 mm film beats the living daylights out of most formats depicted here, especially when it comes to dynamic range.
From the technical point of view, broadcast quality can be thought of as a video signal fulfilling the timing and signal level tolerances placed by the relevant international standards. This doesn't say anything about the bandwidth (resolution) or signal-to-noise ratio of the actual picture -- that remains to be judged from the highly untechnical point of view: considering the contents of the program, is the picture watchable enough? Now that there are plenty of good recording formats available, broadcast quality recording usually means something that isn't noticeably worse than direct composite video from a good camera.
S-Video (or Y/C) does not count as component video, as most externally composite formats use separate chrominance and luminance signals in recording anyway. Additionally, the chrominance signal of S-video is already modulated in either PAL or NTSC to ride on a subcarrier and as such is limited in bandwidth. Component video does not have this limitation.
As you are bound to come across bandwidth specifications in both lines and frequencies, here's how to convert from lines to bandwidth:
4/3 * resolution in lines BW = ----------------------------- / 2. length of active picture lineThe divisor 2 comes from the fact that you need two lines (black and white) to represent a single sine wave cycle. To make things complicated, even the horizontal line resolution is usually expressed as the number of lines that could be reproduced vertically, if the horizontal and vertical resolutions were equal. Therefore the equation contains the multiplier 4/3, which comes from the aspect ratio of television screen. I doubt that all advertisers and salesmen know this.
For 625/50 PAL, the length of the active (visible) part of the picture line is 52 us, so for example the 240 line horizontal luminance resolution of VHS becomes
4/3 * 240 --------- / 2 = 3 MHz 52e-6worth of bandwidth. Of course, we don't know the dB limits for this figure, because nobody told us how gray those 240 "black and white" lines got. For this reason, respectable +/- 1 dB bandwidth specifications may look worse than the same picture quality expressed in lines (which is why lines are preferred in advertisements). Reversing the equation to get from bandwidth to lines is left as an exercise to the reader.
In the specs for component formats, the expressed colour bandwidth applies to both of the colour components separately.
Note: This simplified discussion omits some important points, but will suffice for the usual 4:3 aspect ratio TV systems. If you want the dirty details, consult a good text book like [2]. Furthermore, this conversion method isn't valid for chrominance bandwidth and resolution (I'm still trying to figure out exactly why, but I suppose it's because the colour bandwidth in composite video is limited to some 1.5 MHz in any case).
The same story applies to the digital formats which are represented here. None of them throw away every other line, like CD-i for example does. Even the formats using compression maintain the entire vertical resolution, although all the compression methods are two-dimensional and operate on the image as a whole and not on separate lines.
One can argue that that in PAL, the principle used for colour phase error cancellation reduces the vertical chroma resolution by half. But, this doesn't happen until in the receiver - the video recorders and the PAL video itself still carry the full vertical colour resolution. The exceptions here are VHS and S-VHS, where the method used for track-to-track chrominance crosstalk reduction really cuts the vertical chroma resolution to half on the tape. The chrominance also moves down in the picture. This is hardly notable in the first generation (cf. PAL), but unfortunately degenerates during each copy, so second and third generation VHS copies get barely acceptable and poor, respectively. The results can be seen as those famous "carved-with-an-axe" images.

Note that in C format, the entire composite video signal is recorded and played back as is without splitting it to Y/C, like most composite recorders do, or limiting the bandwidth in any way. Numerous manufacturers include Sony, Ampex and BTS.
U-Matic SP (in common lingo "3/4" after the tape width in inches) is still a popular production format for those not wealthy enough to use Beta SP or similar. Although U-Matic doesn't appear much better than Super VHS on paper, the higher colour resolution and much better signal-to-noise ratio make the picture subjectively far more enjoyable. The U-Matic tape transport is also much faster in changing modes, which makes editing less frustrating.
LB and HB U-Matic tapes are often used for archiving because of the relatively low tape costs and low recording density, which makes the tapes robust against aging.
D-2 was developed by Ampex around the same time as D-1 was introduced and is meant to be a fully transparent storage for composite video, useful for composing "spot tapes" for programmes such as news.
D-3 and D-5 have both been developed by Matsushita. D-5 units can use two different sample rate / resolution combinations and are generally capable of playing back D-3 tapes. While D-5 is still a studio format, D-3 camcorders are available from Panasonic.
A high definition version of D-5 (D-5 HD) has been introduced by Panasonic. It uses 4:1 compression in order to accomodate the 1.2 Gbps HDTV data rate. It can work with both 1080 line interlaced or 720 line progressive (American) HDTV formats.
D-6 is a digital HDTV recording format by Toshiba/BTS. Stores 600 GB worth of data on a physically huge 64 minute cassette. I was told that this format is more or less dead and the remaining tape transports were bought out by Toshiba - but in IBC'97, I saw a D-6 recorder in action, demonstrated as a joint venture between Toshiba and some other Japanese manufacturer, whose name escapes me. The picture quality was truly impressive.
DVCPRO should become D-7 later. Also, Digital-S will be designated as D-9 [unconfirmed].
As a curiosity, D-4 doesn't exist, as number 4 is a major taboo in Asian cultures (pronounced the same as "death" in Japanese). Rumours go that this even delayed the standardization of D-3 and D-5.
The 2:1 compression is based on DCT (discrete cosine transform), like most modern video compression techniques. Each field is compressed separately.
The units can switch between 525/60 and 625/50 operation, and allow a maximum recording time of more than three hours. These qualities give the DCT format a central role in Ampex' electronic film mastering scheme.
As a curiosity, the consumer version (DV) sports one of the densest recording techniques based on magnetic tape media - more than 0.4 megabits per square millimeter. Imagine the data from your 3.5" HD floppy recorded on a single-sided 5x6 mm piece of tape. New equipment from Sony will push this even further with the deployment of LP mode, which will reduce the track width to 6.67 um and multiply the recording time by 1.5. Video specifications will remain the same.
DVCPRO is a professional variant of the DV by Panasonic. The only major difference is doubled tape speed, which is needed for better drop-out tolerance and general recording robustness. It is also capable of 4x normal speed playback. This doesn't mean your run-of-the-mill FF with picture, but accelerated transfer of all of the information into for example a non-linear editing system. DVCAM on the other hand is Sony's variation of the theme, sitting somewhere between DV and DVCPRO. Tape speed and track width have been increased, but not as much as for DVCPRO. Furthermore, it uses the same metal evaporated tape as DV, while DVCPRO uses metal particle tape. What exactly Sony expects from this format is quite puzzling, given that they already have two other digital ENG formats - Betacam SX and Digital Betacam.These similar, but still different digital formats have made some people to fear for another War of the Formats, the players this time being Panasonic and Sony. But because the formats mainly differ in the way they store the data on the tape, the data itself being the same, the situation isn't quite that sad. Actually Panasonic has announced that their upcoming DVCPRO gear will be able to play back DVCAM recordings; according to Panasonic, this will only require reprogramming the capstan servo systems to accomodate for the slightly different track width (15 um in DVCAM vs. 18 um in DVCPRO) and therefore different tape speed.
As for the picture quality, all these variants are nearly broadcast quality, DV being available at nearly consumer prices. For newsgathering and other similar uses, the quality is certainly enough, especially considering that typical postproduction will be done digitally, which will not degrade the quality any further. Compression is mild enough to keep artifacts away in all but problem scenes. The 4:1:1/4:2:0 quantization will be visible if you try something like chroma keying, however. As stated before, the picture quality in all three formats is identical - the targeted market segments are differentiated with the features of the equipment and things like available camera quality.
Recently, DVCPRO has been accepted to be standardized as D-7 by SMPTE. Panasonic has also introduced a 4:2:2 version: DVCPRO-50, which is intended to directly rival Digital S in the professional market.
In the NTSC world, all three DV variants use 4:1:1 sampling. In the PAL versions, DV and DVCAM revert to 4:2:0, whereas DVCPRO uses 4:1:1 globally. Here's a catch - if you dub between PAL DVCPRO and one of the other formats, you'll end up with the worst from both worlds: a 4:1:0 sampled image, where both vertical and horizontal colour resolutions are only half of the conventional broadcast quality 4:2:2 sampling.
A good source for further practical information on DV is DV Central.
Longest tape should be able to store 44.4 GB of data. Recording times depend on the mode used, ranging from 3.5 hours of HDTV to 49 hours of 2 Mbps video in LP mode. Standard mode will record seven hours of video at 19.14 Mbps.
Normally records 1125 lines of analog RGB video, but can switch to an NTSC mode, in which it can either record twice as much high quality NTSC video, or even two different video signals. The latter function is used for field sequential 3D video.
JVC's Digital S editing deck sports a rarely seen feature, video pre-read head, which allows the old video recording to be played back while recording new signal just after that. This makes A/B roll edits possible with just two decks.
JVC also has a web site dedicated to Digital-S.
Despite primarily being a tape format, some decks are actually disk/tape hybrids and provide rudimentary stand alone non-linear editing capabilities. "Briefcase" field editors resembling laptop computers are available, similar to what Panasonic has for its DVCPRO format.
More hype is available on Sony's Betacam SX site.

Where the XSLT specification requires that an error be signaled, Saxon produces an error message and terminates stylesheet execution. In the case of errors detected at compile time, it attempts to report as many errors as possible before terminating; in the case of run-time errors, it terminates after the first error.
Where the XSLT specification states that the processor may recover from an error, Saxon takes one of three actions as described in the table below. Either it signals the error and terminates execution, or it recovers silently from the error in the manner permitted by the specification, or it places the action under user control. In the latter case there are three options: report the error and terminate, recover silently, or (the default) recover after writing a warning to the system error output stream. These actions can be modified by supplying a user-defined ErrorListener.
Handling of individual recoverable errors is described in the table below.
This list is incomplete and needs to be reviewed.

rtfobj is a Python module to detect and extract embedded objects stored in RTF files, such as OLE objects. It can also detect OLE Package objects, and extract the embedded files.
Since v0.50, rtfobj contains a custom RTF parser that has been designed to match MS Word’s behaviour, in order to handle obfuscated RTF files. See my article “Anti-Analysis Tricks in Weaponized RTF” for some concrete examples.
rtfobj can be used as a Python library or a command-line tool.
It is part of the python-oletools package.
rtfobj [options] <filename> [filename2 ...]
Options:
-h, --help show this help message and exit
-r find files recursively in subdirectories.
-z ZIP_PASSWORD, --zip=ZIP_PASSWORD
if the file is a zip archive, open first file from it,
using the provided password (requires Python 2.6+)
-f ZIP_FNAME, --zipfname=ZIP_FNAME
if the file is a zip archive, file(s) to be opened
within the zip. Wildcards * and ? are supported.
(default:*)
-l LOGLEVEL, --loglevel=LOGLEVEL
logging level debug/info/warning/error/critical
(default=warning)
-s SAVE_OBJECT, --save=SAVE_OBJECT
Save the object corresponding to the provided number
to a file, for example "-s 2". Use "-s all" to save
all objects at once.
-d OUTPUT_DIR use specified directory to save output files.
rtfobj displays a list of the OLE and Package objects that have been detected, with their attributes such as class and filename.
When an OLE Package object contains an executable file or script, it is highlighted as such. For example:
To extract an object or file, use the option -s followed by the object number as shown in the table.
Example:
rtfobj -s 0
It extracts and decodes the corresponding object, and saves it as a file named “object_xxxx.bin”, xxxx being the location of the object in the RTF file.
As of v0.50, the API has changed significantly and it is not final yet. For now, see the class RtfObjectParser in the code.
rtf_iter_objects(filename) is an iterator which yields a tuple (index, orig_len, object) providing the index of each hexadecimal stream in the RTF file, and the corresponding decoded object.
Example:
from oletools import rtfobj
for index, orig_len, data in rtfobj.rtf_iter_objects("myfile.rtf"):
print('found object size %d at index %08X' % (len(data), index))


Annif is a statistical automated indexing tool for libraries, archives and museums. After feeding it a SKOS vocabulary and existing openly available metadata from the Finna search engine for library, archive and museum collections, it knows how to assign subjects for new documents.
The first version of Annif (2017, presented in the video below) was a hackish prototype. In 2018 a new version, supporting multiple backends/algorithms and aiming for production use, is being developed at the National Library of Finland. The code is in the NatLibFi/Annif GitHub repository (Apache License 2.0) and a test instance is running at dev.annif.org.
Annif has a REST API and a mobile web app that can analyze physical documents such as books. With Annif, we can add semantics to documents in three projects (Finnish, Swedish and English) using our own indexing vocabulary YSO.
Code for Annif is available on Github (CC0 license).


Detox Instruments uses zero-configuration networking (Bonjour) to discover apps suitable for profiling. This requires no configuration by you under normal circumstances.
The following resources discuss in detail what zero-configuration networking is:
Launching Detox Instruments and starting a new recording, you will be presented with the App selection dialog:
This dialog displays a list of applications which can be profiled by Detox Instruments. The list will populate and update automatically over time, as apps are discovered. Apps running on the same Mac as Detox Instruments will be sorted first, followed by other apps discovered. Enable the Local only option to display only local apps.
Select App Launch in the pop up menu to profile your app's app launch.
For more information on app launch profiling, see App Launch Profiling.
If your app does not appear in the app selection dialog, the following tips will help you troubleshoot.
Make sure you have integrated your app with the Profiler framework. See Profiler Framework Integration Guide for more information
iOS 14 requires local network permission before allowing the discovery and connection to the Profiler service:
If you haven't allowed this permission, you can enable it in Settings app > Privacy -> Local Network:
Devices should be connected on the same network (Wi-Fi, LAN for macOS & Simulators or Lightning cable for direct connection)
If your app is not running on a simulator on the same Mac as Detox Instruments, make sure the Local Apps Only option is disabled
Security software, such as Antivirus and Firewall applications, may interfere with Bonjour; please consult the software manual or contact your system administrator
Corporate networks may block or otherwise prevent Bonjour from working; please contact your system administrator
Under extreme cases, Bonjour may stop working for certain devices. Resetting network settings in Settings > General > Reset > Reset Network Settings is known to help
Note: This will reset all your network settings, including wi-fi passwords, proxy configurations, VPNs, DNS settings, etc. Perform this step with care.

Stress is a function of the demands placed on us and our ability to meet them. These demands often come from outside sources, such as family, jobs, friends, or school. But it also can come from within, often related to what we think we should be doing versus what we're actually able to do. Left unchecked, long-term stress can contribute to a long list of physical and mental health problems. Prolonged stress can cause high blood pressure, weaken the immune system and contribute to diseases such as obesity and heart disease. It can also lead to mental health problems such as anxiety and depression—disorders that are becoming more common in youth.
What Is Stressing You Out Most?
Survey on 11-17 year olds about what was stressing them out. Here are the top 5 things that caused them stress.
As providers and caretakers, adults tend to view the world of children as happy and carefree. After all, kids don't have jobs to keep or bills to pay, so what could they possibly have to worry about? In the short term, stress can push a child to practice for her piano recital or inspire a teen to study when he’d rather be out with friends. But chronic stress is different. Stress in young people doesn’t always look like stress in adults. But like adults, children and teens can find healthy ways to cope. Together, young people and their parents can learn to spot the signs of excess stress and, with the right tools, manage it.
If you are feeling stressed, there are steps you can take to feel better. As you read the following suggestions, remember that conquering stress will not come from a half-hearted effort, nor will it come overnight. It will take determination, persistence and time. Some suggestions may help immediately, but if your stress level doesn’t seem to improve, it may require more attention and/or lifestyle changes. Be realistic.If you feel overwhelmed by some activities (yours and/or your family’s), learn to say NO! Eliminate an activity that is not absolutely necessary. You may be taking on more responsibility than you can or should handle. If you meet resistance, give reasons why you’re making the changes. Be willing to listen to other’s suggestions and be ready to compromise. Shed the “superman/superwoman” urge. No one is perfect, so don’t expect perfection from yourself or others. Ask yourself, “What really needs to be done?” How much can I do? Is the deadline realistic? What adjustments can I make?” Don’t hesitate to ask for help if you need it. Meditate. Just ten to twenty minutes of quiet reflection may bring relief from chronic stress as well as increase your tolerance to it. Use the time to listen to music, relax and try to think of pleasant things or nothing. Visualize. Use your imagination and picture how you can manage a stressful situation more successfully. Whether it’s a business presentation or moving to a new place, many people feel visual rehearsals boost self-confidence and enable them to take a more positive approach to a difficult task. Take one thing at a time. For people under tension or stress, their day-to-day workload can sometimes seem unbearable. The best way to cope with this feeling of being overwhelmed is to take one task at a time. Make a list of things you need to get done and start with one task. Once you accomplish that task, choose the next one. The positive feeling of “checking off” tasks is very satisfying. It will motivate you to keep going. Exercise. Regular exercise is a popular way to relieve stress. Twenty to thirty minutes of physical activity benefits both the body and the mind. Hobbies. Take a break from your worries by doing something you enjoy. Whether it’s gardening or painting, schedule time to indulge your interest. Share your feelings.  Stay in touch with friends and family. Ask them how they have dealt with a similar situation that may be “stressing you out.” Let them provide love, support and guidance. Don’t try to cope alone. Be flexible! If you find you’re meeting constant opposition in either your personal or professional life, rethink your position or strategy. Arguing only intensifies stressful feelings. Make allowances for other’s opinions and be prepared to compromise. If you are willing to be accommodating, others may meet you halfway. Not only will you reduce your stress, you may find better solutions to your problems. Go easy with criticism. You may expect too much of yourself and others. Try not to feel frustrated, disappointed or even “trapped” when another person does not measure up. The “other person” may be a coworker, spouse, or child whose behavior you are trying to change or don’t agree with. Avoid criticisms about character, such as “You’re so stubborn,” and try providing constructive suggestions for how someone might do something differently.


Posts about “Culture”
There were many naysayers when this “magical device” first came out. It’s nothing but a glorified iPod Touch they cried. No front-facing camera. No multitasking (until the Fall that is, when iPhone OS 4 comes out). No USB ports, and so on.
Well I’m not one of those nitpicking technocrats. I think that the iPad is like a shiny piece of the future, straight out of Star Trek. It’s amazing. But here’s the thing: I don’t even own a laptop.
If you’re more concerned with your company culture than the size of your pay cheque, your might be interested in this Vancouver start-up. Jiibe is a user-generated service that matches your value system to a compatible company based on a questionnaire you fill out.
I can see this site being really useful to young Millennials who care a great deal about the softer aspects of job satisfaction and are in a process of self-discovery.
Here are some recent article shorts. As usual, you can click on the thumbnails to read them. The one on the left is a feel-good piece on laughter yoga. The right piece touches on the depressing psychological and cultural effects of global warming. There’s also a teeny one in there on the dodgy air we have to breathe in airplanes (even Purell won’t save you this time).
Seeing these two articles juxtaposed like this evokes a stark contrast between Western frivolity and Aboriginal reality.
The May edition of alive magazine is out, and I have two articles published in it this month. A few months ago I interviewed stress guru Eli Bay about his relaxation techniques. Take a deep breath, relax for a few minutes and read his insights.
I also wrote a short piece on the rise of the mosquito population in our new era of rising temperatures. Mosquitoes love warm, moist climates, and they’re getting a lot of that these days.
Canadian Business magazine has just released their annual report on Canada’s best places to live. Our cold and sober capital, Ottawa, graced the number one spot based on factors like household income, unemployment rate, and new cars (New cars? Really? What does splashing out on some smoking wheels have to do with livability?). Vancouver shuffled in at number 10. And what impoverished, crappy-car-driving town came in last at number 154?
The cultural differences in the perception of colour are well known to anthropologists. Red, for example is bold and signifies anger in the West, but is considered lucky in the East, especially in China. But do web designers take the cultural colour faux pas into consideration? They should. Especially if designing for international clients. After all, colour is a tricky beast and just because you happen to be in love with mauve, it doesn’t mean your client will.
Over at Wired’s video gallery you can watch some amusing tech vintage commercials. While I find the ones for the old Mac, the Vic-20, and the Commodore chuckle worthy, my vote for the funniest - and the most creative - goes to the 1980s ad for the Atari 5200’s Pole Position. Back in those days, the marketing strategy was basically to show as little of the game’s graphics as possible while hyping up the game in various ridiculous ways.
Can governments read people’s minds with radio waves? Many people believe so. In fact, in order to combat this unseen menace, a paranoid subculture has arisen around the wearing of tin foil hats. This seemingly bizarre practice has garnered such credibility that an MIT student conducted empirical research in order to debunk it. Curiously, his findings indicated that tin foil in fact amplifies certain radio frequencies. Ironically, or perhaps tellingly, the frequencies amplified are the very same governmental and corporate frequencies that paranoids are trying to avoid.
When editing technical documents, how aware should you be of regional differences in pronunciation? Here is an interesting article on the subject by Brian Forte. Forte raises the following issue regarding the usage of an indefinite article with initialisms:
How do you pronounce an initialism like HTML?
I was taught English in public Australian schools of the 1970s. So I was taught aitch rather than haitch. Which means I pronounce ‘HTML’ with an initial vowel sound and I write ‘an HTML page.

System Monitoring with Sar
sar is part of the sysstat project, a suite of programs for system monitoring. With sar, we can log system activity, build performance reports and even make plots.
sar is available on Linux, Solaris, AIX and HP-UX.
We can choose to run sar automatically, as an unattended script. Or interactively and get system metrics on the spot.
Unattended Mode
With a simple cron entry we can log system activity. If possible, as root, otherwise some data may be missing.
# cron entries, take a sample every 10 minutes
@reboot /usr/lib/sa/sa1 --boot
*/10 * * * * /usr/lib/sa/sa1 1 1 -S DISK
The @reboot
line is kind of optional, but if the cron supports it’s good to have since it ensures the counters are reset
on boot.
sa1
is script that calls sadc
, which does the actual collection.
To prevent the files from growing too large not everything is stored, however
additional counters can be enabled with -S
.
Optional collection options for sadc:
- DISK block devices
- XDISK block devices and partitions
- INT system interrupts
- IPV6 network IPV6 statistics
- POWER power management
- SNMP is for the SNMP statistics
- ALL everything except XDISK
- XALL everthing including XDISK
Also check sysstat’s config for compression and retention options. /etc/conf.d/sysstat or /etc/default/sysstat
To access the stored data we have two alternatives:
sa2
is a script that generates an activity report for the previous day (/var/log/sarNN). This can be croned easily:
# generate daily activity report
00 18 * * * /usr/lib/sa/sa2 -A
The other way is calling sar
directly, this lets us choose the view:
# sar views with extended options
-u [ALL] CPU utilization (default view)
-b I/O rates
-d block device activity
-F mounted filesystem statistics
-n ALL network statistics
-P ALL per processor statistics
-q queue and load average
-r [ALL] memory utilization
-H hugepages utilization
-S swap space utilization
-B paging statistics
-W swapping activity
-v inode and kernel tables
-w task/process creation
-y TTY device activity
-m ALL power management statistics
-I ALL interrupts
-A Everything
Some views have additional options, for example -n ALL
shows all network activity (including protocols) while -n DEV
only shows network devices.
sar by default shows today’s logs, -1
brings yesterday’s, -2
the day before yesterday and so on.
 We can log system activity while doing some other tasks. Perhaps while running a benchmark or doing some troubleshooting.
With the -o
option, sar stores/appends data in a file or directory.
sar takes a sample interval (in seconds) and count that works as a stop condition.
# collect activity in my_metrics file, 1 sample per second, 60 samples total
sar -o my_metrics 1 60
Linux 4.19.8-arch1-1-ARCH (ix) 12/24/2018 _x86_64_ (4 CPU)

...
If you’ve used mpstat before, you’ll recognize the format, it’s exactly the same.
To retrieve the results we use -f
.
We can use a different interval or count and the output will be filtered appropiately.

Exporting Sar’s Data
Wouldn’t it be great to be able to export the collected data? Maybe to a database or a spreasheet?
Don’t we deserve some nice plots? No worries, sadf
has us covered.
sadf syntax is a bit quirkier:
sadf [options] [ <interval> [ <count> ] ] [ <datafile> | -[0-9]+ ] -- [sar options]
options:
-p table
-d CSV
-r raw CSV (as read from the kernel)
-x XML
-d JSON
-g SVG
The options to the right of the --
are sent to sar for printing the report, here we can choose what views to export.
To select the log file we can use either 0
, -1
, etc for daily logs (as in the unattended mode) or just
provide the path to the datafile.
# export yesterday's I/O activity in CSV
sadf -d -1 -- -b
# hostname;interval;timestamp;tps;rtps;wtps;bread/s;bwrtn/s
ix;1;2018-12-26 17:58:06 UTC;20.00;0.00;20.00;0.00;168.00

ix;1;2018-12-26 17:58:09 UTC;71.00;0.00;71.00;0.00;624.00
...
# export CPU activity from my_metrics file in JSON
sadf -j my_metrics -- -u
{"sysstat": {
"hosts": [
{
"nodename": "ix",
"sysname": "Linux",
"release": "4.19.8-arch1-1-ARCH",
"machine": "x86_64",
"number-of-cpus": 4,
"file-date": "2018-12-26",
"file-utc-time": "17:58:05",
"statistics": [
{
"timestamp": {"date": "2018-12-26", "time": "17:58:06", "utc": 1, "interval": 1},
"cpu-load": [
{"cpu": "all", "user": 16.11, "nice": 0.00, "system": 10.58, "iowait": 0.00, "steal": 0.00, "idle": 73.32}
]
},
...
With -g
we get SVG output that we can redirect into a file.
# export CPU activity as SVG plot
sadf -g -- -u > cpu.svg
# export network activity for device eth0 as SVG plot
sadf -g -- -n DEV --iface=eth0 > a.svg

Wrapping Up
For sure, there are a lot of more options available, I just can’t cover them all, but I think the basics were covered.
That’s all for now. If interested on system monitoring, sure to check my previous article about vmstat.
Have a good one.

Women in tech: how to improve the industry
“Où sont les femmes?”
July 10th, 2015
“Où sont les femmes?”, litteraly translated: “Where are the women?”, is a question french singer Patrick Juvet already asked in 1977 (don’t judge my music taste, it’s not great music, but it got popular back then). He was wondering about the consequences of feminism, not something we will really be discussing today, but still, our friend Patrick is looking for women. And so is the tech industry!
If you are reading this blog, you are somewhat familiar with the tech industry and some of its issues, then you know that women are largely under-represented in this industry. And it’s a real problem, when there is no girl around, guys get awkward. The less diversity the more awkwardness, that may not sound like a genuine problem but it is and we’ll see later why. Another key problem is lack of diversity itself, because a lack of diversity in gender also means a lack of diversity in approaching problems and thinking through solutions. A tech industry with more women would be a more efficient and innovative industry.
First let’s try to understand what happened here. According to data gathered from the National Science Foundation Women were way more present in Computer Science departments of colleges in the mid eighties than they are today. The proportion actually flattened in 1984, then decreased uninterruptedly until it flattened out again in 2007.
So, what happened here!? The main explanation is mind-blowingly simple. I’m using “main” since there could be other assumptions. The first mainstream computers were not that smart, they were essentially used to play games and could some word processing, so they were essentially marketed to boys and men. Studies have shown that girls generally prefer reading when learning or entertaining themselves, they tend to stay away from video games. That may explain why girls are generally smarter, but that’s only a personal remark and, full disclosure, I completed 100% of Gran Turismo in the summer of ’98, “dumb boy” would apply to me. A few years on, the boys grow to careers in computer sciences, when girls are just not that into computers.
I used the adjective “main” earlier, because there is another self-reinforcing phenomenon at work. As the tech industry became a boys club, it became more and more awkward with girls. A good way to observe that was to attend tech conferences a few years back, it culminated in 2009 at a Ruby conference where someone gave a talk subtitled “Perform Like a Pr0n Star,” with sexy slides. This is disheartening, to say the least. There has been criminal indictments too. Since then, the industry started adopting stronger codes of conducts. But there is a long way to go.
So, “Où sont les femmes?”
Right here, at Dev Bootcamp! Coding bootcamps are increasingly shaking the tech industry, reshuffling the cards of education. Take the example of my DBC cohort: there are 13 girls out of 27 students, 48% of the cohort, more than twice the proportion found in computer science colleges! Talking’ ‘bout a revolution . This alone is the proof that this form of education is the future, what an uplifting prospect! All that remains is to teach old skeletons how to behave, the tech industry will then be genuinely better!

Write a class with a main()
method that
asks the user for the name of the input file
to be read by the program.
In a practical program, the name would then be
used to access a disk file
(see Part 10 of these notes.)
But for this program just gather the file name.
The file name must be in the correct format. File names consist of two parts, a name and an extension. The name must not contain spaces. The extension must be ".dat" (for "data"). The user is repeatedly asked for a file name until it meets the requirement.
C:\>java filePrompt input file: glarch >>>file name must end with .dat<<< input file: my file.dat >>>file name must not contain spaces<<< input file: .dat >>>file name missing<<< input file: myData.dat OK C:\>
Use methods of the String class to
manipulate the user's input.
Another approach is the use the
class StringTokenizer
,
a subject of a future chapter.
Click here to go back to the main menu.
Improve the first version of the square root program of the chapter by repeatedly prompting the user until the number that is entered is positive.
Do this by inserting a nested
do/while
inside the
loop body of the
do/while
that asks if the user wishes to continue.
Improve program so that the user must respond exactly with "yes" or "no".
C:\>java squareRoot Enter a number--> -3 >>>number must be positive<<< Enter a number--> 3 Square root of 3.0 is 1.7320508075688772 Do you wish to continue (yes or no)? na >>>Please respond with (yes or no)<<< Do you wish to continue (yes or no)? no Bye C:\>
In this program the main purpose, computing and printing the square root, is easily done in a few statements. However, the user interaction calls for some fairly complicated logic. This imbalance is typical of user friendly programs.
Click here to go back to the main menu.


For this project we need users. Users will be helpfull for our adress book and for our authentication process.
Users will be define with at least a first name and a last name. We also need an unique identifier to retreive the user.
Note
For this tutorial the file yyou create will be named app.py To launch your application then just type in a terminal:
python app.py
from rest_api_framework import models
class UserModel(models.Model):
fields = [models.StringField(name="first_name", required=True),
models.StringField(name="last_name", required=True),
models.PkField(name="id", required=True)
]
The use of required_true will ensure that a user without this field cannot be created
We also need a datastore to get a place where we can save our users. For instance we will use a sqlite3 database. The SQLiteDataStore is what we need
from rest_api_framework.datastore import SQLiteDataStore
We want results to be rendered as Json. We use the JsonResponse view for that:
from rest_api_framework.views import JsonResponse
To create an endpoint, we need a controller. This will manage our endpoint in a RESTFUL fashion.
from rest_api_framework.controllers import Controller
class UserEndPoint(Controller):
ressource = {
"ressource_name": "users",
"ressource": {"name": "adress_book.db", "table": "users"},
"model": UserModel,
"datastore": SQLiteDataStore
}
controller = {
"list_verbs": ["GET", "POST"],
"unique_verbs": ["GET", "PUT", "DElETE"]
}
view = {"response_class": JsonResponse}
then we must run our application:
if __name__ == '__main__':
from werkzeug.serving import run_simple
from rest_api_framework.controllers import WSGIDispatcher
app = WSGIDispatcher([UserEndPoint])
run_simple('<IP_ADDRESS>', 5000, app, use_debugger=True, use_reloader=True)
So far, all of the code should look like this:
from rest_api_framework import models
from rest_api_framework.datastore import SQLiteDataStore
from rest_api_framework.views import JsonResponse
from rest_api_framework.controllers import Controller
class UserModel(models.Model):
fields = [models.StringField(name="first_name", required=True),
models.StringField(name="last_name", required=True),
models.PkField(name="id", required=True)
]
class UserEndPoint(Controller):
ressource = {
"ressource_name": "users",
"ressource": {"name": "adress_book.db", "table": "users"},
"model": UserModel,
"datastore": SQLiteDataStore
}
controller = {
"list_verbs": ["GET", "POST"],
"unique_verbs": ["GET", "PUT", "DElETE"]
}
view = {"response_class": JsonResponse}
if __name__ == '__main__':
from werkzeug.serving import run_simple
from rest_api_framework.controllers import WSGIDispatcher
app = WSGIDispatcher([UserEndPoint])
run_simple('<IP_ADDRESS>', 5000, app, use_debugger=True, use_reloader=True)
Note
to launch your application, just type in a terminal:
python app.py

Federer eyes Djokovic after rebounding against Berrettini
Roger Federer got back on track at the ATP Finals with a 7-6(2) 6-3 defeat of Italian Matteo Berrettini on Tuesday.
LONDON: Roger Federer got back on track with a 7-6(2) 6-3 defeat of Italian Matteo Berrettini on Tuesday and immediately set his sights on a crunch clash with Novak Djokovic that will decide his ATP Finals fate.
Defeat by Austrian Dominic Thiem in his opening round-robin match on Sunday has left the 20-time Grand Slam champion facing only his second group stage exit in 17 appearances at the year-ender.
He repaired some of the damage with an emphatic victory over Italian debutant Berrettini, but will likely need to beat Djokovic to avoid falling before the semi-finals of a tournament he has won a record six times.
Their 49th meeting will take place on Thursday and will be their first clash since Djokovic beat Federer in July's epic Wimbledon final - in which the Swiss held two match points before losing a fifth-set tiebreak.
"We'll find out, but I think it's all flushed away from my side. A lot of water has gone under the bridge since then," Federer said when asked if the memory of that Centre Court defeat was still a bitter one.
"I think we both can take away some confidence from the match. Him obviously a lot. Me maybe a tad bit less.
"But at the end of the day, I didn't hope I was never going to play him again. Actually, it's good for me to play him again, and maybe that all helps to get a chance to get him back or whatever it is. Personally, excited to play Novak on Thursday."
Federer looked far sharper than he did against Thiem although the powerful Italian pushed him hard.
Once Federer won 10 of 11 points to win the first-set tiebreak and break to love at the start of the second, he never looked like suffering another defeat.
Incredibly Federer is now 17-0 in second round-robin matches at the tournament.
The 23-year-old Berrettini was also coming off a heavy defeat by Djokovic in his first appearance at the event, and he showed why he has made such an impact this year.
Berrettini, the first Italian to qualify for the tournament since 1978, had three break points in the eighth game of the second set but Federer served his way out of trouble and the 38-year-old Swiss then broke to claim victory.
After being thrashed by Federer at Wimbledon this year, afterwards calling it a tennis lesson, Berrettini was far happier with their second meeting.
"Today I was more ready. I knew what I had to do to win, to try to win the match," he said.
Djokovic, who is bidding to equal Federer's record of six titles and claim back the world number one ranking from Rafael Nadal, faces Thiem later on Tuesday at the O2 Arena.

I was down in Washington DC for school and I was pretty bored one night and my friend was going to a rave in the city at a random location. Good idea I thought. we got to the rave and it was pretty small with a good flow of drugs but I felt I needed acid because I haven't done it before. My friend said that he knew somebody with drops.
To cut to the chase he came over and I purchased 4 drops. I held out my hand and he dosed me. after he yelled over the music,'did I get you?'. I saw my opportunity 'no man' I said so he dosed me 4 once again.
 The walls were flowing like goddamn waterfalls and the graffitti on the walls were floating by me.
What's strange is that I could see the music vibrations in the air. Jjungle 'music' really messes with you. I remember that during the trip that everything was too clear and so clear that all I wanted to do was kill myself. The reality of the world was too much for me to take. The sparkle of life was taken away and I saw the behind the scenes look at life and it was depressing as hell.
Life was falling apart at the seams and I had to sit at this apartment with people I didn't know and listen to them talk about the most pointless things. But I noticed that they were all putting blankets around each other and there was a wind blowing through the room (it wasn't wind from outside.) It was like they were helping each other survive. I wondered what are they surviving against? After thinking I came to the conclusion, LIFE.
