New UK bill can fight fresh wave of online racist abuse Expert comment NCapeling 21 July 2021

The Euros final and Grand Prix put online abuse once more in the spotlight. The UK’s Online Safety Bill provides a strong framework for tackling the problem.

The ugly online abuse targeted at members of the England football team following the Euros final, and then at Lewis Hamilton after the British Grand Prix, was not only hateful to the individuals concerned, but divisive for the UK more broadly.

More needs to be done to regulate online platforms to avoid the spread of such abuse at scale. Online platforms are making increasing efforts to ‘self-regulate’ in order to tackle online abuse. Over the past year, Facebook and Twitter have strengthened their policies on hateful speech and conduct, such as Facebook’s policy banning Holocaust denial. Both have become more vigilant at deplatforming those who violate their terms of service, such as Donald Trump, and at removing online abuse using a combination of machines and humans.

Twitter announced in the 24 hours following the Euros final that it had removed more than 1,000 tweets, and permanently suspended several accounts, for violating its rules. But inevitably not all abusive posts are picked up given the scale of the issue and, once the post has been seen, arguably the damage is done.

Platforms have also partnered with NGOs on initiatives to counter hate speech and have launched initiatives to tackle the rise in coordinated inauthentic behaviour and information operations that seek to sow distrust and division. But while these efforts are all laudable, they are not enough.

The root of the problem is not the content but a business model in which platforms’ revenue from advertising is directly linked to engagement. This encourages the use of ‘recommender’ algorithms which amplify divisive content by microtargeting users based on previous behaviour, as seen not just with racist abuse but also other toxic content such as anti-vaccination campaigns. Abusers can also remain anonymous, giving them protection from consequences.

Creating a legal duty of care

The UK government’s Online Safety Bill, published in May 2021, aims to tackle harmful content online by placing a duty of care on online platforms to keep users safe and imposing obligations tailored to the size, functionality, and features of the service.

Social media companies will be expected to comply with their duties by carrying out risk assessments for specified categories of harm, guided by codes of practice published by the independent regulator, OFCOM. The bill gives OFCOM the power to fine platforms up to £18 million or ten per cent of global turnover, whichever is higher, for failure to comply.

Following the Euros final, the UK government spoke of referring some racist messages and conduct online to the police. But only a small proportion of it can be prosecuted given the scale of the abuse and the fact only a minority constitutes criminal activity. The majority is ‘lawful but harmful’ content – toxic and dangerous but not technically falling foul of any law.

When addressing ‘lawful but harmful’ material, it is crucial that regulation negotiates the tension between tackling the abuse and preserving freedom of expression. The scale at which such expression can spread online is key here – freedom of speech should not automatically mean freedom of reach. But it is equally important that regulation does not have a chilling effect on free speech, as with the creeping digital authoritarianism in much of the world.

The Online Safety Bill’s co-regulatory approach aims to address these tensions by requiring platforms within the scope of the bill to specify in their terms and conditions how they deal with content on their services that is legal but harmful to adults, and by giving the regulator powers to police how platforms enforce them. Platforms such as Facebook and Twitter may already have strong policies on hate speech – now there will be a regulator to hold them to account.

Devil is in the detail

How successful OFCOM is in doing so will depend on the precise powers bestowed on it in the bill, and how OFCOM chooses to use them. It’s still early days - the bill will be scrutinized this autumn by a committee of MPs before being introduced to parliament. This committee stage will provide an opportunity for consideration of how the bill may need to evolve to get to grips with online abuse.

These latest two divisive and toxic episodes in UK sport are only likely to increase pressure from the public, parliament, and politicians for the bill to reserve robust powers for OFCOM in this area. If companies do not improve at dealing with online abuse, then OFCOM should have the power to force platforms to take more robust action, including by conducting an audit of platforms’ algorithms, enabling it to establish the extent to which their ‘recommender’ settings play a part in spreading hateful content.

Currently, the bill’s definition of harm is confined to harm to individuals, and the government has stated it does not intend this bill to tackle harm to society more broadly. But if racist abuse of individuals provokes racist attacks more widely, as has happened, the regulator should be able to take that wider context into account in its investigation and response.

Responses to the draft bill so far indicate challenges ahead. Some argue the bill does not go far enough to tackle online abuse, especially on the issue of users’ anonymity, while others fear the bill goes too far in stifling freedom of expression, labelling it a recipe for censorship.

Parliamentary scrutiny will need to take into account issues of identity, trust, and authenticity in social networks. While some call for a ban on the cloak of anonymity behind which racist abusers can hide online, anonymity does have benefits for those in vulnerable groups trying to expose hate.

An alternative approach gaining attention is each citizen being designated a secure digital identity, which would both provide users with greater control over what they can see online and enable social media platforms to verify specific accounts. Instituted with appropriate privacy and security safeguards, a secure digital ID would have benefits beyond social media, particularly in an online COVID-19 era.

The online public square is global so countries other than the UK and international organizations must also take measures. It is encouraging to see synergies between the UK’s Online Safety Bill and the EU’s Digital Services Act, published in draft form in December 2020, which also adopts a risk-based, co-regulatory approach to tackling harmful online content. And the UK is using its G7 presidency to work with allies to forge a more coherent response to internet regulation at the international level, at least among democratic states.

Addressing the scourge of online hate speech is challenging so the UK’s Online Safety Bill will not satisfy everyone. But it can give the public, parliament, and politicians a structure to debate these crucial issues and, ultimately, achieve more effective ways of tackling them.

Kip Thorne, Rainer Weiss, Barry Barish and Ronald Drever | Smithsonian Magazine’s 2016 American Ingenuity Award Winners for Physical Sciences In February, physicists announced the first-ever detection of gravitational waves—a phenomenon Albert Einstein predicted back in 1915. The faint reverberation, from two merging black holes 1.3 billion light-years ago, registered in the two giant detectors that make up the Laser Interferometer Gravitational-Wave Observatory, or LIGO. It took decades for LIGO’s founders—Weiss, of MIT, and Thorne and Drever, of Cal Tech—to amass the necessary funding and brainpower. Barish, a particle physicist at CalTech, became LIGO’s director and expanded its work to include more than 1,000 researchers worldwide. Their revolutionary achievement opens the way for a new understanding of the universe, perhaps even a glimpse of the Big Bang.

Hi! I've made some 1-point waveform "markers" that I want to overlay in my plots to aid visualization (with the added advantage, w.r.t. normal Viva markers, that they update location automatically upon refreshing simulation data).

For example, the plot below shows an spectrum along with two of these markers, which I create with the function "singlePointWave", and the Assembler output definitions also as shown below.

The problem is: as currently created and defined, Assembler is unable to plot these elements. I can send their expressions to the calculator and plotting works from there, BUT ONLY after first enabling the "Allow Any Units" in the target Viva subwindow.

Thus, I suspect Assembler is failing to plot my markers because they "lack" other information like axes units and so on. How could I add whatever is missing, so that these markers can plot automatically from Assembler?

Thanks in advance for any help!

Jorge.

P.S. I also don't know why, but nothing works without those "ymax()" in the output definitions--I suspect they are somehow converting the arguments to the right data type expected by singlePointWave(). Ideas how to fix that are also welcome! ^^

procedure( singlePointWave(xVal yVal)
    let( (xVect yVect wave)
        xVect = drCreateVec('double list(xVal));
        yVect = drCreateVec('double list(yVal));
        wave = drCreateWaveform(xVect yVect);
    );
);

Hi Cadence, 

I use simvision 20.09-s007 but my computer screen resolution is very high. As a result, the texts are too small. 

In ~/.simvision/Xdefaults I changed that number to 16, from 12. But the signal names in the waveform traces don't reflect the change. 

Simvision*Font: -adobe-helvetica-medium-r-normal--16-*-*-*-*-*-*-*

Other .font changes seem to reflect on the simvision correctly, except the signal names. 

How do I fix that? I dont mind a single variable to change all the texts fonts to 16. 

Thank you!

PS: I found the answer with another post. I change Preference/Waveform/Display/Signal Height. 

I'm currently trying to explore the verilog simulation option in cadence.

One thing that comes to my mind that if there exists a way in cadence workflow to dump selected register/wire's waveform during the simulation. 

Are there any additional tools needed apart from xcelium, is there a tutorial or specific training course for this aspect. I glance through Xcelium Simulator Course Version 22.09, but it seems not having related context. 

I know in Synopsys's workflow, it can be realized using verdi & fsdb in the command line as follows:

if (inst.CTRL_STATE==STATE_START_TO_DUMP)

$fsdbDumpvars(0, inst_1.reg_0);

end

Thanks in advance!

hi,

     I save the waveform file of the oscilloscope as CSV file format.

     Now, I need to use this waveform file as the source of the low-pass filter .

     I searched and read the PSPICE help documents, and did not find any  methods. 

     How to realize it?

     Are there any reference documents or examples?

Hello Everybody

Recently, I want to design a high output Power Amplifier at 2.4GHz using TSMC 1P6M CMOS Bulk Process. I use its nmos_rf_25_6t transistor model to determine the approximate mosfet size

I use the most common Common-Source Differential Amplifier topology with neutralizing capacitor to improve its stability and power gain performance

Because I want to output large power, the size of mosfet is very large, the gate width is about 2mm, when I perform harmonic balance analysis, everything is alright, the OP1dB is about 28dBm (0.63Watt)

But When I perform Transient simulation, the magnitude of voltage and current waveform at the saturation point is too small, for voltgae, Vpeaking is about 50mV, for current, Ipeaking is about 5mA

I assume some reasons: the bsim4 model is not complete/ the virtuoso version is wrong (My virtuoso version is IC6.1.7-64b.500.21)/the spectre version is wrong (spectre version is 15.1.0 32bit)/the MMSIM version is wrong/Transient Simulation setting is wrong (the algorithm is select gear2only, but when I select other, like: trap, the results have no difference), the maxstep I set 5ps, minstep I set 2ps to improve simulation speed, I think this step is much smaller than the fundamental period (1/2.4e9≈416ps)

I have no idea how to solve this problem, please help me! Thank you very very much!

Hi,

Do anyone know if it's possible in simvision waveform viewer to see a timestamp of where uvm_errors/$errors occurred in a simulation via post-processing? 

Cheers,

Antonio

Hello,

First, I had something working that broke in the past few versions that I've been meaning to get working again. There was some setting I recall in the GUI that allowed me to have inputs be placed in the waveform viewer with yellow traces, and output signals with orange traces to match the name colors. How can I set this to happen in the .simvisionrc file?

Second, I would like to add something to my .simvisionrc file to go through foreach signal and depending on key locations based on the signal's Path.Name (mainly the model and design areas) such that if the path contains "mon", then to auto-set the trace and name colors to something such as cyan. I'd like to have loops for various key areas of the design to color-code the signals.

Third, I am interested if there is a possibility of coloring names/traces foregound colors to based on which position they are in the waveform viewer to make banding, ideally such that every three (or whatever) are one color (or a color mutation, adding some gray to signals colorized by the auto-coloring mentioned already, etc) that allows for the signal names/traces to be colorized along with the built-in optional black/gray background banding.

Thanks in advance
