#python 3 modules

[cosmogyros]

Thank you so much for this guide! I have one question for OP or anyone else who's done this successfully:

When it comes to installing the dependencies, e.g. the line: pip install tumblr-backup[video] ...my command line doesn't seem to like the square brackets. (At least, I'm assuming they're the problem here.)

When I try to enter that command, I get this error: zsh: no matches found: tumblr-backup[video]

Has anybody else had a similar experience? Am I doing something wrong? Are you not actually supposed to type the square brackets verbatim?

FWIW I'm doing this on macOS, not Linux, but all the commands look familiar so I think it ought to work if I can get over this one hurdle...

ETA: I know square brackets on the command line indicate something optional, but in that case, what do I actually type? Neither "pip install tumblr-backup video", with a space, nor "pip install tumblr-backupvideo", without a space, seem to work.

Quick Tumblr Backup Guide (Linux)

Go to www.tumblr.com/oauth/apps and click the "Register Application" button

Fill in the form. I used the following values for the required fields: Application Name - tumblr-arch Application Website - https://github.com/Cebtenzzre/tumblr-utils Application Description - tumblr archival instance based on tumblr-utils Adminstrative contact email - < my personal email > Default callback URL - https://github.com/Cebtenzzre/tumblr-utils OAuth2 redirect URLs - https://github.com/Cebtenzzre/tumblr-utils

Get the OAuth Consumer Key for your application. It should be listed right on the www.tumblr.com/oauth/apps page.

Do python things:

# check python version: python --version # I've got Python 3.9.9 # create a venv: python -m venv --prompt tumblr-bkp --upgrade-deps venv # activate the venv: source venv/bin/activate # install dependencies: pip install tumblr-backup pip install tumblr-backup[video] pip install tumblr-backup[jq] pip install tumblr-backup[bs4] # Check dependencies are all installed: pip freeze # set the api key: tumblr-backup --set-api-key <OAuth Consumer Key>

So far I have backed up two blogs using the following:

tumblr-backup --save-audio --save-video --tag-index --save-notes --incremental -j --no-post-clobber --media-list <blog name>

There have been two issues I had to deal with so far:

one of the blogs was getting a "Non-OK API repsonse: HTTP 401 Unauthorized". It further stated that "This is a dashboard-only blog, so you probably don't have the right cookies. Try --cookiefile." I resolved the issue by a) setting the "Hide from people without an account" to off and b) enabling a custom theme. I think only step a) was actually necessary though.

"Newly registered consumers are rate limited to 1,000 requests per hour, and 5,000 requests per day. If your application requires more requests for either of these periods, please use the 'Request rate limit removal' link on an app above." Depending on how big your blog is, you may need to break up the download. I suspect using the "-n COUNT" or "--count COUNT" to save only COUNT posts at a time, combined with the "--incremental" will allow you to space things out. You would have to perform multiple passes though. I will have to play with that, so I'll report back my findings.

--- 30 days of productivity • COLLAB CHALLENGE WITH @studaxy • Day 26/30 ---

💛 Axy's productive time: 1h 32min

💙 Iris's study time: 2h

Today I did an activity because I was bored. My textbook said that implementing the "finding GCD of numbers by prime factorization method" into a program is hard, and I went "are you challenging me?"

So yeah I spent the day doing that and turns out it was pretty hard lol XD but! I ended up succeeding!

Also, I learned about the Counter module in python, which creates a dictionary of items — the keys being the elements of an iterable passed to it, and the values being the number of occurrences of the key in the iterable. So that was fun :3

BLACK SWAN- ✧˖°BTS Challenge - 𐙚

Main concept: of this challenge is that I have to bring my passions back to life that died long ago

Bit inspired by @zzzzzestforlife 🍾🫶🏻

As in song's lyrics of 'black swan'

"If this can no longer resonate, no longer make my heart vibrate, then like this may be how I die my first death."

[ You can reblog this post and start this challenge by yourself after adding your own goals under the reblogged post of yours... :)) ]

[ Academics:- ᥫ᭡🎐

As to bring back my interest in studies there are some goals of mine and some tips (I am referring myself as 'you' as some external force for myself) 🎀

☆ By the mid of September you must be on track in academics - complete notes and zero backlogs , regular revision ! 📄❕️❕️

☆ 📌 Complete pw modules till December

☆ work on weak chapters🗯 - relation and functions , trigonometry , periodic classification and topic electronic configuration of chapter - 2 of chemistry 💨

☆ listen to podcasts like 'ACADEMIC VALIDATION'🗒and 'YOUR A+ LIFE'📈 while studying mathematics. (As I kinda not get maths yk )

☆ study along with study vloggers - 'STUDY WITH ME' 🩰 because it helps when you find a 'partner' in studying.

☆ Have a mindset that you are not a student but you are a employee working for a greater position in your job or for greater income....🏷 which means position- topper or sum and income - grades ⏳️

☆ while studying physics you should use whiteboard 📇cuz I know it gets boring at times so yea

☆ for chemistry I would say that read books and make pretty pretty notes 🪄 and if you still can't study it then just watch some study vlogs and restart 🎲 (it helps me sometimes)

☆ study computer science chapter of - 'PYTHON' 🖥 whenever you get time as of getting mind off STEM subjects

[ Workout :- ᥫ᭡ 🎳

☆ I know it's not easy getting off bed but just use 1-2-5 minute rule 🎗

-stand up for 1 minute and drink some water

- start off with some stretching next for 2 minutes

- do 4 plank sessions in 5 minutes or any other favourite exercise move of yours

(This is my concept btw) And this will help about 70 percent to actually get you up.🥊

☆ do pilates in case you don't feel like exercising⛳️

☆ do 'lazy' stretching either before sleeping ot after sleeping.🎯

☆ walk minimum 6k steps a day♠️

[ Hobbies/Extra curricular :- ᥫ᭡ 🎱

☆ subscribe/follow to multiple dance pages so you automatically get the urge to dance🪀

☆ watch your idol dancing...it helps🧩

☆ dance atleast twice a week no matter what , even if you have to force it. It will individually get better if you were some day passionate bout it once.👯🏻‍♀️

☆ start writing your incomplete book by visualizing the scenes of the book...may help sometimes🖇

☆ during breaks from studies play basketball even for 5 minutes... put your phone away and walk around with your basketball around you then you will automatically feel the urge.🏀

☆ take part in school activities as much as you can....I get it that there is lot of academic work but it shouldn't stop you from being an all rounder🏆🏅

[ Social :- ᥫ᭡🥂

☆ cut people off...yea exactly CUT THEM OFF !! Lot of people don't really deserve you. You know who those people are.🌬

☆ don't get too comfy with some people. I get it that its your nature but keep that aside rn because it can be pressuring your self respect.🛑

☆ cut off atleast 3 people this year (atleast)💬

☆ don't be too kind to endure every other 'tease' of thiers. No this degrades your self respect and standards✋🏻

☆ if they are constantly mean then cut them off or just give them what they deserve(be the karma).🗣

☆ be as much confident as you can.you know nothing is cringe.... your definition of cringe is limiting you from your potential.🧭

So this is it for this challenge. I will regularly add more goals if needed and keep on updating my process.

You all are free to join :))🍾💐

boring diary / brain dump, day 88 / 2025

Tsukaretaaaaaaa (but that's nothing new)

Didn't go swimming this week yet. Meeting L tomorrow. Extremely confused about which day it is. Still can't eat any food at all. Scaler 3 is out. KV didn't get back to me about the potential music lesson. Should go to Finland next week but I don't think I have the energy, even walking 45 minutes in a day, with breaks, is proving too difficult.

But, I had my first lesson with L about Python today. It's always interesting to someone get into programming for the first time ever. We spent an hour talking about life and the meta of programming. Some variables, some functions, REPL, modules. Simple stuff. But at the same time, very complicated stuff. I always try to use metaphors for things in real life ("function is like a recipe") but it hits limits of the metaphor real fast. I definitely need to work on those, as bad metaphors are more misleading than no metaphor.

Asking for money is harrrdddd though. Genuinely thinking I'll ask about disability status next week, even if it's just a bit of extra money. Just can't imagine asking 40 euro an hour from someone who is half my age and works for near minimum wage.

Studying code calmly and avoiding a burnout. Day 1

If you saw a list of tasks that I said I would do until 23:59 on Sunday, you realized that was a lot for 3 days.

And guess what, he almost had a burnout of his own doing? Myself IEEJIJEIJIE

Yesterday, learning with my elders and colleagues, I understood that I wanted to do a lot of things and almost had my third burnout just to show the recruiter what I can do if I pass the process I want.

BUT it won't do me any good to have a github full of repositories, if I have a burnout and I don't want to touch the code and it gets worse if I'm in a work process because then I'm going to miss a hell of a chance because in the past I've done more than that I could.

SO today Monday I set myself small goals.

[ ] Finish the 1 module Javascript course

[ ] Take the Introduction to computer science with python (1 and 2)

[ ] Object orientation with python

[ ] Project 1 final with Html, css and bootstrap + a bootstrap course individual

I changed plans and that lightened the load. Now I think I can handle it and not freak out.

I will try to make daily updates. I want to be proud of myself in the future when I look at all this bullshit bounout, frustration, etc. And I also share it here for the sake of ego/vanity and wanting to be heard/seen. Which is fine, as long as it's not hurting anyone.

(I don't need any advice comments about ego and vanity. I already have someone to teach me about and I deal very well with my shadows, thank you.)

I wish you a great week, drink water, sunbathe if possible and don't give up.

Project Euler #2

Welcome back to my series on Project Euler problems. HackerRank Lets get into it.

Links:

Project Euler: https://projecteuler.net/problem=2 HackerRank: https://www.hackerrank.com/contests/projecteuler/challenges/euler002

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1,2,3,5,8,13,21,34,55,89,… By considering the terms in the Fibonacci sequence whose values do not exceed N, find the sum of the even-valued terms.

So first thing to note is just how odds and evens work. This starts with 1 and 2 so Odd + Even = Odd, then the next term would just be Even + Odd = Odd. It isn't until the 3rd addition that we get Odd + Odd = Even. After that this cycle will repeat.

So really what this is asking for is, starting at index 2, what is the sum of every 3rd term less than N.

F(2) + F(5) + ... + F(3k + 2)

(Where F(N) is the Nth Fibonacci number)

Now, computing Fibonacci numbers notoriously sucks to do, with the naive way of doing it causing you to compute from just F(20) would require computing F(3) like hundreds if not thousands of times over. So the best way to do it is to create either a hash or a cache to store it. I'm going to be utilizing something built into Python, "lru_cache" from the "functools" module. It'll just store the answers for me so I don't have to recompute what F(10) is thousands of times.

Here's my HackerRank code:

import sys from functools import lru_cache @lru_cache def fibonacci(N: int) -> int: if N < 0: return 0 if N <= 1: return 1 return fibonacci(N-1) + fibonacci(N-2) t = int(input().strip()) for a0 in range(t): n = int(input().strip()) x = 2 f = fibonacci(x) total = 0 while f <= n: total += f x += 3 f = fibonacci(x) print(total)

So as you can see, I just start at 2 and keep incrementing by fibonacci number by 3 each time. Then the loop will stop when my fibonacci number exceeds N.

And that's all tests passed! Onto the next one!

Natural Text to Speech (python)

Microsoft Edge has very good, natural-sounding Text to Speech voices used in its "Read Aloud" feature. You can utilize these voices using python and a module called edge-tts (edge text to speech) to generate audio files of whatever text you like, including subtitles (for free).

Install python if you haven't already

Use pip to install edge-tts in your favorite command line

Run the CLI commands or create a new .py file. I suggest starting with this basic audio generation example.

Replace the TEXT variable contents with your string of choice. I recommend creating separate .txt files then reading them with the program, which allows you to cleanly scale your program to generate multiple files at once. (Imagine crawling your Obsidian vault to generate audio versions of all of your files!)

Choose your voice. You can use the Read Aloud feature in Edge to try out the different available voices (their quality varies). Their programatic voice names are found here. Note that not all voices are available, depending on your region, and trying to use one out of your region will throw an error. Read the footnotes. I'm still early in testing the different voices, but if you want to start on the right foot, Ava, or "en-US-AvaMultilingualNeural" is very good.

If you run the above example, it will generate a file called test.mp3 in the directory of the .py file. It's definitely performant. I ran a ~10k word file and it took a couple of minutes to generate (~23 MB with a running length of 1 hour and 3 minutes).

Have fun!

Added voice samples for the two I like the most, Ava and Brian multilingual.

Python Day 2

Today I am starting off with exercise 13. Exercise 13 introduces the concepts of variables, modules, and argv.

[ID: Exercise 13 code. It imports the argv module from sys, then uses argv to create 4 variables, script, first, second, and third. Next print() is used to print out the different variables /ID]

When calling the program I was confused as to why I got the error of too many variables. Looking into this I found that the first variable of 'argv' is always going to be the script. I then fixed that and added in script as the first variable.

Next for the study drill I wrote a new variable and updated the code to print the retrieved information.

Alrighty then - onto exercise 14. Exercise 14 is about practicing prompts and variables.

In the study drills I updated the script with a new prompt and print statement.

Exercise 15 is a simple program that prints out the contents of a file. An important thing to note is to always close the file when doing things like this!

Exercise 16 practices making a copy of a file and then updating it with 3 lines from user input.

I ended up running into the issue where it was saying that it couldn't read the file. I ended up finding out that .read() starts from the cursor position - and if the cursor is at the end of the file from writing it you will not have your file printed.

Exercise 17 is practicing copying files over and was relatively simple.

Matrix Breakout: 2 Morpheus

Hello everyone, it's been a while. :)

Haven't been posting much recently as I haven't really done anything noteworthy- I've just been working on methodologies for different types of penetration tests, nothing interesting enough to write about!

However, I have my methodologies largely covered now and so I'll have the time to do things again. There are a few things I want to look into, particularly binary exploit development and OS level security vulnerabilities, but as a bit of a breather I decided to root Morpheus from VulnHub.

It is rated as medium to hard, however I don't feel there's any real difficulty to it at all.

Initial Foothold

Run the standard nmap scans and 3 open ports will be discovered:

Port 22: SSH

Port 80: HTTP

Port 31337: Elite

I began with the web server listening at port 80.

The landing page is the only page offered- directory enumeration isn't possible as requests to pages just time out. However, there is the hint to "Follow the White Rabbit", along with an image of a rabbit on the page. Inspecting the image of the rabbit led to a hint in the image name- p0rt_31337.png. Would never have rooted this machine if I'd known how unrealistic and CTF-like it was. *sigh*

The above is the landing page of the web server listening at port 31337, along with the page's source code. There's a commented out paragraph with a base64 encoded string inside.

The string as it is cannot be decoded, however the part beyond the plus sign can be- it decodes to 'Cypher.matrix'.

This is a file on the web server at port 31337 and visiting it triggers a download. Open the file in a text editor and see this voodoo:

Upon seeing the ciphertext, I was immediately reminded of JSFuck. However, it seemed to include additional characters. It took me a little while of looking around before I came across this cipher identifier.

I'd never heard of Brainfuck, but I was confident this was going to be the in-use encryption cipher due to the similarity in name to JSFuck. So, I brainfucked the cipher and voila, plaintext. :P

Here, we are given a username and a majority of the password for accessing SSH apart from the last two character that were 'forgotten'.

I used this as an excuse to use some Python- it's been a while and it was a simple script to create. I used the itertools and string modules.

The script generates a password file with the base password 'k1ll0r' along with every possible 2-character combination appended. I simply piped the output into a text file and then ran hydra.

The password is eventually revealed to be 'k1ll0r7n'. Surely enough this grants access to SSH; we are put into an rbash shell with no other shells immediately available. It didn't take me long to discover how to bypass this- I searched 'rbash escape' and came across this helpful cheatsheet from PSJoshi. Surely enough, the first suggested command worked:

The t flag is used to force tty allocation, needed for programs that require user input. The "bash --noprofile" argument will cause bash to be run; it will be in the exec channel rather than the shell channel, thus the need to force tty allocation.

Privilege Escalation

With access to Bash commands now, it is revealed that we have sudo access to everything, making privilege escalation trivial- the same rbash shell is created, but this time bash is directly available.

Thoughts

I did enjoy working on Morpheus- the CTF element of it was fun, and I've never came across rbash before so that was new.

However, it certainly did not live up to the given rating of medium to hard. I'm honestly not sure why it was given such a high rating as the decoding and decryption elements are trivial to overcome if you have a foundational knowledge of hacking and there is alot of information on bypassing rbash.

It also wasn't realistic in any way, really, and the skills required are not going to be quite as relevant in real-world penetration testing (except from the decoding element!)

Good afternoon TUMBLR - March 23th - 2024

''Mr. Plant has owed me a shoe since July 5, 1971."

January 1998 - October 1999 - NLNG - TSKJ Port Harcourt Project (Nigeria).

Part 3.

SWIMMING SUIT I hadn't brought a swimsuit from Italy, and since we spent Sunday in one of the hotel pools in the area, I decided to buy one. I told the driver to take me to a location where I could find one, he stopped the Land Rover in front of a small shop along Aba Road. There were different types and colors of swimsuits inside, in the end I opted for one in red and blue. Before the shopkeeper placed it in the usual supermarket plastic bag, I wanted to take one last look - and here's the ''surprise'': IT WAS 2nd HAND!! But the most incredible thing was that they had put it up for sale with ''clear signals'' of those who had used it before!!! I told the sales man: at least wash it? Naaa…… I left with a mixture of fury and disbelief: I couldn't belive to what my eyes have seen.

SOKU PROJECT SITE

Niger river - On the way to Soku.

As mentioned elsewhere, the Soku Gas Plant was a project that SAIPEM Nigeria was executing in parallel to our TSKJ project. The site was located about 2 hours by speed boat from Port Harcourt, in the middle of the Niger River Delta. All around there was a dense rainforest, so to avoid cutting down thousands of trees it was decided that the plant would be built on an artificial island in the middle of the river. A Spanish company specialized in dredging and construction of artificial islands (called reclaimed land) was commissioned and within 6 months a 1.5 km by 800 meter platform was ready to begin work. A camp was built by importing portacabins from SAIPEM NORWAY (yes, you read that right). The reasons behind SAIPEM Procurement was:

''If they are good for the cold of Norway, they will also be good for the tropical forest of Nigeria''. Carlo Sgorbani arrival to Port Harcourt. Sgorbani was also an ''old'' SAIPEM guy. I met him during the Bir Rebaa project in Algeria. I then found it again in Abu Dhabi for the Taweela aWater Project, where during the last part of the project he assumed the position of Site Manager (And immediately left our compound to rent a villa at Hilton hotel). An early one morning I went to Branch Office and met Sgorbani who was still under shock due the night flight from Paris.

Ohh...I cant believe to my eyes! How come you're here Carlo?

And he, with the perpetual cigarette in his hand: well… I should be the Site Manager of the Soku Gas Plant project…

Soku Gas Plant?? But… are you sure of what you say? I'm quite sure there are any Hilton villas in Soku….... well, come on… you can't always go for luxury… and then you'll see that the ex-Norway containers won't be so uncomfortable!

He didn't reply.

SAIPEM Club SAIPEM has always cared about the ''welfare'' of its employees located in the most sh****hole remote and difficult areas of the planet. Therefore the Management decided to install a clubhouse inside the Soku compound. As soon as the Worry project structure was made available, it was transported by barge to Soku. It consisted of different container modules, and inside it had a billiard room, ping pong, TV room, bar with tables where can play cards in the evening. Behind the bar counter, above the shelves that held the bottles of liquor, a long python skin had been fixed. And this will cause several problems.

PYTHON STRIKE The morning after the club inauguration, Sgorbani and all the other colleagues were woken up by strange moans and screams coming from inside the camp. They immediately rushed to the front of the club and found themselves in front of dozens of people lying on the ground crying, wriggling and sprinkling sand on their heads. Local people were screaming like:

Our Lord is dead…you killed our Lord our Lord is dead…you have killed our God....... All the expatriates present could not understand what was going on before their eyes. Sgorbani called the local PRO, who revealed the burden:

''Sir – he said – these people are telling that you from SAIPEM captured and killed their Lord, and then after having slaughtered him you hung his skin in your club, offending his memory even more – now they expect years of disgrace if nothing is done to remedy this tragedy."

But…but…All of this is inconceivable – replied Sgorbani – the python skin was hung on the wall of the bar when the structure was in Warry, months ago, not here……….

I know, Sir – said the PRO – but these people say that this was why they hadn't seen their Lord for months: he had migrated to Warry, someone from SAIPEM captured him and made him a trophy.

Sgorbani and all other expats know whether to laugh or get angry at what they had heard and what was happening in front of them - however the Site Manager understood that laughing at the matter could generate further and serious problems - so he asked the PRO:

Ok… okay… so what should we do?

Sir – said the PRO – I spoke with their Chief and he says that the only solution to this serious matter is to call a Great Medicine Man who lives in Calabar (about 200 km from Soku) Only he will be able to exorcise the bad influences caused to what SAIPEM people did. But first of all we need to remove the python skin off the bar wall, Sir.

Ok – replied Sgorbani – we'll do it right away, but in the meantime we have to get back to work!

No Sir, until everything is resolved, work cannot resume.

Sgorbani was about to fly into a rage, but was able to contain himself - he ordered the PRO to proceed as quickly as possible with the call of this ''medicine man'' - that he should come immediately, SAIPEM would spare no expense, and would do everything needed made available, starting from the speed boat. Two days of great tension passed in the camp and on the artificial island. Time seemed suspended, waiting for the arrival of the sorcerer who would resolve the drama. An eerie silence loomed over everything and everyone, when construction activities usually filled the place with noise. In just two days (a great achievement considering that it was happening in Nigeria) the ''Great Medicine Man of Calabar'' arrived in great pomp, dressed in traditional clothes, covered by a bright apple-green cloak, with a headdress of peacock feathers and studded with precious stones (nobody knew if true or fake…).

Between two wings of the crowd who knelt as he passed on the way from the docking pier to the club, the sorcerer distributed blessings with his inlaid staff. No one, except the faithful, was allowed inside the club, where, after a brief ceremony, the python skin was peeled off the wall and carefully carried outside by at least six weeping people. The skin was carried as if in procession to the pier, where a previously prepared canoe transported it across the river to the vicinity of the village where the local tribe lived. A pit had been dug there which, covered with a white sheet, welcomed the python's skin. Once the skin was wrapped, the burial proceeded, accompanied by songs, blessings and mysterious formulas recited by the Great Medicine Man, who every now and then drew water from a drum with a palm leaf and sprinkled the grave. Once filled with earth, flowers and tree branches were planted on the tomb, and the area was marked off with stones. The funeral was over, and the sorcerer moved on to collect the money from SAIPEM PRO - the cost of the entire "ceremony was over 20,000 dollars. The next day, work at site could finally resume.

ATTACK on SOKU COMPOUND Perhaps the python affair had been a sort of ''dress rehearsal'' to see the type of response that SAIPEM would have given to an emergency. The fact is that a few weeks passed, and a new big problem arose for Sgorbani and the SAIPEM expatriates on Soku project. It was an August hot morning, when they woke up with a noise caused by rifle and stick blows that an handful of ''rebels'' were giving to their dormitory containers who had come from Norway. After a few minutes, all the expatriates were gathered in front of the offices, and when asked by the one who seemed to be in charge "where the Chief was", the answer was that he was in his office. (Sgorbani used to get up very early). Some rebels entered the offices, and to make it clear that they had serious intentions, they fired a couple of rifle shots which fortunately did not hit Sgorbani, but lodged in the wall behind his head. He too was pushed into the square in front of the offices, and made to lie on his stomach like everyone else. The rebels claimed to have taken possession of the artificial island of SOKU and the site, to put an end to the indiscriminate exploitation of the River State's resources. They wanted money, hiring of local staff, salary increases for those already working with SAIPEM, construction of a school and a hospital in the adjacent community. These intentions would be followed by an ultimatum, after which if the requests were not accepted by the local governments and the top management of SAIPEM, they would begin to eliminate a hostage every 2 hours. While all this was happening, the Nigerian Army Security forces had surrounded the artificial island. A long-distance dialogue then began between the Major who led the military and the guy who professed to be the leader of the rebels. The military's strategy immediately appeared clear:

''First free the hostages and then we will sit down for negotiation'' - this was the message delivered to the attackers. Who naturally refused, demanding at least the delivery of a large sum of cash, the arrival of the local Governor, who should have handed himself over to them, to unblock the situation. In the meantime, time passed, and the time set for the expiry of the ultimatum approached, and the hostages were still on the ground with their hands behind their heads. The tension mounted as the hours passed, and when there were only a few minutes left before the ultimatum expired, suddenly the Security forces attacked the Rebels! Taken by surprise, many of them tried to escape, others took some of the hostages by force to shield themselves from the military fire. For a few minutes there was total chaos: shots, shouts, the rebels trying to reach some canoes hidden among the branches on the river bank, to escape capture. The clashes lasted a few minutes, and soon everything was silent, only a few sporadic bursts could be heard from the automatic weapons with which the Task Force eliminated the remaining resistance. Some rebels were captured and immediately knocked to the ground with rifle butts. Most of the hostages had fled to the dormitory containers and locked themselves inside. Once order was restored, the Major asked to speak to Sgorbani.

Do you have a couple of empty containers?

Yes, of course – replied the Site Manager

Have them taken to an open, sunny area. Zaccagnini had the order carried out, and after an hour the SAIPEM crane deposited two empty containers in an open area on the island. The Major then ordered his men to let the captured rebels enter the containers. When the operation was concluded, the containers were closed with heavy padlocks, and the Major set up guards. Then he said aloud:

''No one must go near the containers, this scum must remain awaiting the decisions of the Military Tribunal of Port Harcourt''.
