Sigamos con la #Hidrovía
Acá vimos su relevancia para la economía y lo caro e inconveniente del contrato firmado y ampliado por gobiernos peronistas.
Pero por suerte en Abril 2021 vence ese contrato y se puede volver a licitar.
Si @alferdez quiere, claro.
Antes permítanme recordarles lo particular de nuestra #Hidrovía.
Por año ingresan 4400 buques, la mayoría hasta el Gran Rosario. En pocos lugares del mundo un buque oceánico ingresa 600km tierra adentro!!
Eso es posible por la naturaleza (ríos anchos) pero también por el dragado
Es decir, tenemos la suerte de tener condiciones naturales. Qué no darían muchos países del mundo por tener nuestros ríos! Y esa barranca rosarina que reduce el costo de elevación! 🥰
Pero para prosperar en un mundo globalizado hay que ayudar a la Naturaleza con infraestructura.

It was strange that @NITDANigeria required immediate compliance with its #NDPR, whereas EU had a 2yr period for #GDPR. Not surprising, many organisations aren't compliant and citizens aren't aware of their rights under NDPR- @SolomonOkedara

#SMWLagos2020
@TheLodt
Private citizens whose privacy and other info-related rights could be violated ate a critical factor in enforcement. This is a key reason for a period of sensitization prior to implementation of #NDPR - @SolomonOkedara

Talking about the culture of factuality and Veracity, lack of a national ID system allows Nigerians play fast and loose with information, thus affecting data quality-- Emmanuel Agha (Innovectives Ltd) at @TheLodt's #BigData panel yesterday.

Although a #fintech entrepreneur myself, I've noted violations of regulations & standards on customer information request. E.g. there're Nigerian apps which do not allow you onboard until location info is disclosed, which is wrong- Emmanuel Agha #BigData

Of the 5 'Vs' - Volume, Variety, Velocity, Veracity & Value - the most important is Value. What you can do with your info is the main gist of #BigData

@dejitoye
#BigData assumes data in 'gazillions' of bytes. Nigeria hasn't arrived at that scale in data Volume yet, especially in externally generated Variety. H/ever, organisations should also plan to extract Value from internal Data- Prof. David West @LBSNigeria #SMWLagos2020
@TheLodt
Because of limited volume in externally generated data, the secondary market for #BigData is not yet a thing in Nigeria. Also, weak culture of factuality affects Veracity, and dearth of talent in data mining affects Value- Prof. David-West @LBSNigeria #SMWLagos2020

Why mid-sized companies are behind the #datascience curve: A thread—
Mid-sized companies are behind in terms of being data-driven when compared to startups and large entities. There are several reasons for this which puts them at a disadvantage.
1/ The average age of a mid-sized company is c years. X years older than the average startup and large entities such as Facebook or Apple. Overall, their workforce is older as well which translates into greater domain knowledge and also little technical capability.
2/ There is often a greater majority of non-technical works which places a heavy burden on the few technical workers often leading to burnout, limitations and ultimately churn.

Disappearing subsidies are driving #innovation across decentralised generation. New ways of trading and sharing local electricity are coming @NewAngliaEnergy @exeterepg @Comm1nrg @Regen_insight @EnergyREV_UK @EnergySysCat @NatureEnergyJnl @energycities @Bankfieldbecky
Extending the definition of 'self' consumption to neighbourhoods and communities can really improve the viability of decentralised generation. This #p2p model is one way, but we think that micro trades can make local energy projects too 'markets' focussed. I.e. not fun 😑

1/7 With all the Warren, Eastern Metis and Chumash #pretendian stories flitting about, there isn't much opportunity to speak about the core issues of #AmerindigenousDisempowerment I hope my colleague forgives me using her video for my own purposes.
2/7 1) Amerindigenous groups are divided, as they have been since 1492. But they are united by ancestry and genomic evolution. 2) Amerindigenous groups are divided by colonial mindsets / language (Spanish & English, Puritans & Catholics, Segrationalist vs Aggregationalist Racism)
3/7 3) Divided by Affinity to whiteness and belief that we've lost the "If you can't beat them, join them mentality " (flag worship, military service, religion) 4) Divided by intra-Amerindigenous grudges over actions that were products of Colonial war and alliances.

As we close this year and think about the decade ahead, nothing has impacted us more than technology. Arguably, social media platforms have become the central nervous system of our communication worldwide.
It’s so important that we understand how these platforms that were created to connect us are being weaponized against us. We need to understand how our data is being monetized, how micro-targeting for political ads works, who has our information and how they are using it.
We’re coming into 2020 with tons of new information to keep the conversation going. Thank you to everyone who has watched the film and created awareness in your communities.

Puede o no gustarnos el #KPOP, pero el #BigData tiene una definición precisa. Lo que hemos visto hoy por parte del Gobierno de Chile es una tergiversación de un concepto. Igual o peor que cuando todos los políticos hablaban de Web 2.0. 1/7
La definición de Big Data más amplia se refiere a la naturaleza de los datos. Para que los datos (data) sean considerados "grandes datos" (big data) deben cumplir con las 3V: Volumen, Variedad y Velocidad. 2/7
Ejemplo sumamente claro de Big Data: Datos astronómicos. En Chile los radiotelescopios registran mucha información, a gran velocidad y además es información variada respecto de estrellas y planetas. Para saber más de eso siga a @jayvains. 3/7

A thread on this interesting piece by Hagiu & Wright on the data advantage. hbr.org/2020/01/when-d… @theplatformguy #bigdata #antitrust 1/10
The piece makes 2 key points: (1) there is a data advantage only under some conditions & (2) the data-enabled network effect is less powerful than the standard network effect 2/10
My views: the first point is uncontroversial. The second point is not necessarily true in all circumstances, and anyway it doesn't necessarily matter when discussing the data-enabled network effect 3/10

Our latest paper fresh out in @ATHjournal! We asked: "If we used an #AI algorithm to group individuals based on similar blood profile of 44 #lipid measurements, could we improve coronary #heartdisease risk prediction?" Turns out: no.

Thread! 🚨 (1/13)

atherosclerosis-journal.com/article/S0021-…
We looked to see if we could detect subgroups in the population that would have a) similar blood profiles across 14 lipoprotein subclasses and b) possible differences in CHD risk. The algorithm we use is called a self-organising map (SOM)

See: academic.oup.com/ije/article-ab… (2/13)
SOM is a tool for multivariate subgrouping. Essentially the user puts in variables and the algorithm groups individuals based on similarity of these inputs. Here's a rough emoji-schematic of how this applies to population cohorts (3/13)

This is an exceptionally important article about @google and health care data being provided by @Ascensionorg, without patient or doctor knowledge. So do we, as a society care – what protections are there? @ChrisMurphyCT @SenBlumenthal @rosadelauro wsj.com/articles/googl… @WSJ
@Google @Ascensionorg @ChrisMurphyCT @SenBlumenthal @rosadelauro @WSJ Why was the project begun in secret? Especially given #privacy issues? 'Google began Project Nightingale in secret last year w/St. Louis-based Ascension, a Catholic chain of 2,600 hospitals, doctors’ offices and other facilities, w/data sharing accelerating since summer.’ @WSJ
@Google @Ascensionorg @ChrisMurphyCT @SenBlumenthal @rosadelauro @WSJ According to @WSJ: "Neither patients nor doctors have been notified. At least 150 Google employees already have access to much of the data on tens of millions of patients, according to person familiar w/the matter and the documents.” Do why not notify everyone before you start?

We really need to talk about #history, dear Data-will-safe-the-future-folks.

This is a ridiculous take and stunningly disconnected from all the brilliant debates on history of data-science / history of #bigdata in the last years. #histstm

theguardian.com/technology/201…
There was this in 2017, a great Osiris issue on #Datahistories, asking about the histories of data and data-sets and reminding everyone to have a second look at the question, if big data is the answer. journals.uchicago.edu/toc/osiris/201…
Or one could look at this issue in HSNS, where de Chadarevian & Porter ( and all other authors) where doing an excellent job of 'scrutinizing the data world' hsns.ucpress.edu/content/48/5

One of the unsung triumphs of the Trump Admin is the application of #BigData to detecting fraud & crime.
I suspect that is what happened here after a 22-year crime spree against the military acquisition system comes to an end.
#ButNothingsHappening
Seems our alleged criminal spent 22-years winning bids to provide parts & supplies to the US military by being the low bidder. Of course he was the low bidder because his companies didn't exist & didn't manufacture the parts.
He just bought them from China & other places...
Then sent the substandard parts & the military paid up prior to testing if the parts met the standards of the contracts. When they didn't, they would reject the parts, but he would close up the shell companies when they came to collect. FOR 22 YEARS!

OK. I promised a thread about the paper and promises must be kept.
Let's use this thread to talk about #DNAdatastorage in general and finish up with our work and some thoughts about the future of the field.
1/10
Why use DNA to store data?
As the burden of the #BigData era on data storage infrastructure is becoming too heavy we need to explore alternatives.
DNA was optimized as an information carrier by billions of years of evolution. It's dense, stable, and energetically efficient.
2/10
Back in 2012 we saw two important studies demonstrating MB scale data storage on synthetic DNA. @geochurch was the first with an elegant straight forward approach. @Nick_Goldman followed with a more robust encoding.
Since, others has shown encoding/technological improvements
